Answer:
920000 or 9.2 x 10⁵
Step-by-step explanation:
Given:
It takes the sun 2.3 x 10⁸ years to orbit the milky wayIt takes Pluto 2.5 x 10² years to orbit the sunGiven this we want to find :
How many times pluto orbits the sun over the time span that the sun makes one orbit around the milky wayTo get this we must divide the time it takes Pluto to orbit the sun by the amount of time it takes the sun to orbit the milky way
In other words our answer = 2.3 x 10⁸ / 2.5 x 10² = 920000
We can then convert the outputted number into scientific notation
In doing so we get 9.2 x 10⁵
Its important to note that the coefficient (9.2) must have 2 significant figures as the given numbers do.
All we did to convert to scientific notation is add a decimal in between the two sig figs and multiply (9.2) by 10 to the power of how many decimal places we moved over to get to 9.2. Here we moved the decimal point 5 places from 920000. to get to 9.2 therefore the answer in scientific notation would be 9.2 x 10⁵
(You can easily calculate this by plugging this into a calculator)
SUN
2.3 • 10^8= 230000000
PLUTO
2.5 • 10^2 = 250
DIVIDE SUN BY PLUTO
230000000/250 = 920000 Answer

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Answers
Answer:
Step-by-step explanation:
Let's start by finding the sum of the list of nine numbers, which we can then use to find the value of the remaining two numbers in the list:
Sum of the nine numbers = mean * number of numbers = 17 * 9 = 153
Let the three modes be a, b, and c. Since they are modes, each of them must appear at least twice in the list.
Let's assume that the numbers in the list are arranged in non-decreasing order. Then we have:
a ≤ b ≤ c
Since a, b, and c are modes, each of them must appear at least twice in the list. We have three cases to consider:
Case 1: Each of a, b, and c appears exactly twice in the list.
In this case, the remaining three numbers in the list are:
x1 = a + 4
x2 = b + 1
x3 = c - 8
We know that x1, x2, and x3 are distinct and not modes of the list. Therefore, they must be among the six numbers in the list that are not equal to a, b, or c. Let's call these numbers d, e, and f, where:
d ≤ e ≤ f
Then we have:
a + b + c + x1 + x2 + x3 + d + e + f = 153
3(a + b + c) + 3(d + e + f) = 153 + x1 + x2 + x3
Since x1, x2, and x3 are distinct and not modes of the list, we have:
x1 > c
x2 > b
x3 < c
Therefore, we can write:
x1 = c + k1
x2 = b + k2
x3 = a + k3
where k1, k2, and k3 are positive integers.
Substituting these expressions into the equation above, we get:
3(a + b + c) + 3(d + e + f) = 153 + a + b + c + k1 + k2 + k3
Simplifying, we get:
2(a + b + c) + 3(d + e + f) = 153 + k1 + k2 + k3
Since k1, k2, and k3 are positive integers, the right-hand side of this equation is at least 3. Therefore, we have:
2(a + b + c) + 3(d + e + f) ≥ 156
We want to find the value of 3(a + b + c), so let's isolate this term:
3(a + b + c) = 2(a + b + c) + (a + b + c)
Since the left-hand side is three times the sum of a, b, and c, and the right-hand side involves the sum of a, b, c, d, e, and f, we need to express d, e, and f in terms of a, b, and c.
From the inequality a ≤ b ≤ c, we have:
a + k3 ≤ b + k2 ≤ c + k1
Adding 4 to the first inequality, we get:
a + k3 + 4 ≤ b + k2 + 4 ≤ c + k1 + 4
Adding -8 to the second inequality, we get:
a + k3 + 4 ≤ c + k1 - 4 ≤ b + k2
Therefore, we can choose d = a + k3 + 4, e = c + k1 - 4, and f = b + k2. Then

Answer:
H. 95°
Step-by-step explanation:
m∠BGC is 10° smaller than m∠CGD, which means that m∠BGC is x° - 10°
m∠DGE is 25° more than m∠EGF, which means that m∠DGE is x° + 25°
The sum of all angles in a placement like this will always equal 360°
So we put all the measures of all angles on one side of thee equation and set it equal to 360*
x° + x° - 10° + 2x° + 25° + 2x° + 3x° + 30° = 360°
After combining like terms we get 9x° + 45° = 360°
After some algebra we get x = 35°
Now at the start we said that m∠DGE is x + 25°
Plug in 35° for x and we get 35° + 25°
The final answer is m∠DGE = 95°

what is the median weight of the mice ?

⇔ 0.71 , 0.66 , 0.63 , 0.73 , 0.70 , 0.68 , 0.66 , 0.66 ⇔
Answers
Answer: 0.66
Step-by-step explanation:
The median is the MIDDLE NUMBER of a group of numbers.
Grouping the mice weights in order from least to greatest can help solve the problem quickly.
-> 0.63, 0.66, 0.66, 0.66, 0.68, 0.7, 0.71, and 0.73.
After that, you cross out each of the numbers starting with 0.63 and 0.73 going toward the middle, to get the odd one out, which is 0.66.
So, 0.66 is the median weight of the mice.
answer : the median is 0.67
0.71 , 0.66 , 0.63 , 0.73 , 0.70 , 0.68 , 0.66 , 0.66
first you would arrange it from least to greatest :
0.63, 0.66, 0.66, 0.66, 0.68, 0.7, 0.71, 0.73
Since you have an even set of numbers you take the two numbers in the middle and find out which number is exactly in between those, so in this case it would be 0.67

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answers
Answer:
6
Step-by-step explanation:
18-2.5+7 there s your helllppppppppppp
New base = 18 x 2/5 = 7.2 feet
New height = 7 x 2/5 = 2.8 feet
Therefore, the dimensions of the new deck are 7.2 feet for the base and 2.8 feet for the height.
Part B: To find the area of the original deck, we can use the formula for the area of a triangle, which is:
Area = (1/2) x base x height
Area = (1/2) x 18 x 7 = 63 square feet
To find the area of the new deck, we can use the same formula and plug in the new dimensions:
Area = (1/2) x 7.2 x 2.8 = 11.88 square feet
Therefore, the area of the original deck is 63 square feet and the area of the new deck is 11.88 square feet.
Part C: The ratio of the areas is:
63/11.88 = 5.303
The scale factor is:
2/5 = 0.4
To compare the ratio of the areas to the scale factor, we can divide the ratio of the areas by the scale factor:
5.303/0.4 = 13.2575
Therefore, the ratio of the areas is 13.2575 times the scale factor.

Barbara runs a lemonade stand to raise money for Barton Children's Hospital. Last weekend, she made 8 liters of lemonade to sell. Saturday was rainy, so she only sold 8 glasses. The weather was better on Sunday, so she sold 24 glasses. If each glass holds 200 milliliters, how many liters of lemonade does Barbara have left?
PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!
Answers
Answer:
1.6 liters of lemonade
Step-by-step explanation:
There are 1000 milliliters in one liter so she made 8000 milliliters of lemonade
Next we have to figure out how many milliliters of lemonade she sold each day:
Saturday: 200 milliliters of lemonade in a glass * 8 glasses = 1600 milliliters of lemonade sold
Sunday: 200 milliliters of lemonade in a glass * 24 glasses = 4800 milliliters of lemonade sold
1600 + 4800 = 6400 total milliliters of lemonade sold
Since there are 1000 milliliters in one liter, we have to divide 6400 by 1000:
6400 ÷ 1000 = 6.4 liters
Lastly, we have to subtract 6.4 from 8:
8 - 6.4 = 1.6 liters of lemonade

In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
Answers
Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.
Step-by-step explanation:
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.

Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units
the perimeter is 194.6 units
