Which situation could be represented by the equation 15.5=x2?

Julie drove 15.5 miles to the grocery store. Her mother drove from the grocery store back home. What is x, the amount miles each person drove?

It is 15.5 miles to the grocery store from Julie's home. On the way to the store, she decided to take a detour which shortened her distance by half a mile. What is x, the new distance to the grocery store including the detour?

Julie drove 15.5 miles from her home to the grocery store. Julie drives the same path going back home. What is x, the total amount of miles traveled to the grocery store and back home?

Julie went to a grocery store 15.5 miles away. Amanda also went to a grocery store 15.5 miles away. The grocery store was half way in between their houses. What is x, the distance from Julie's home to the grocery store?

Answer:

0 (\(\sqrt{0}\) = 0)

Step-by-step explanation:

If 0^2 = 0 because 0 x 0 = 0, then the reverse function (square root) would result in 0.

Answer:

960in³

Step-by-step explanation:

The formula to find volume is (length * width * height) or (base * height).

1. Multiply the length and width to get 96in².

2. Multiply 96 by the height to get 960in³.

The volume of the cooler is 960in³

Answer:

960

Step-by-step explanation:

if you multiply 12 and 10 you will get 120 then multiply 120 by 8 and you will get 960.

Aristocracy is a form of government in which political power is held by a select few privileged people called aristocrats or nobles. Coming from a Greek word meaning “rule by the best,” aristocrats are considered the most qualified to rule because of their moral and intellectual superiority.

Answer: It is greater than 2

Step-by-step explanation:

Answer:

greater than 2

Step-by-step explanation:

4+7x-2

========================================================

Explanation:

Combine the like terms in choice A to find that:

Therefore, choice A simplifies to 7x-6.

Choice B on the other hand simplifies to 7x+2 since 4-2 = 2.

The expressions 7x-6 and 7x+2 don't match up, which means the answer is either choice A or choice B.

--------------

Let's simplify choice C.

Choice C simplifies to 7x-6 which matches with choice A. In other words, choices A and C are equivalent expressions. We can rule out choice A and go with  choice B   as the final answer.

For the sake of completeness, let's simplify choice D

8x-x-6 = 7x-6

This shows choice D matches with A and C.

Answer:

Its correct.

Step-by-step explanation:

Answer:

300=120/100* number of tickets sold last week.

So last week's number of tickets=300÷(120/100)=300*100/120=30*100/12=5*100/2=5*50=250 tickets

So the answer is 250

Answer:

Mean = 33.7

Median = 34.5

Mode = 34

Range = 33

After adding 26....

mean decreases by 0.7

median decreases by 0.5

mode is 34

range is 33

Step-by-step explanation:

mean = sum of all the data values/number of data values

= (18 + 19 + 20  + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7

To find median arrange the values in increasing order, find the mid value

If the number of data points is even, find the average of the mid 2 data values

Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51

Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5

The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once

Mode = 34

The range is highest - lowest = 51 - 18 = 33

After we add 26, we get the following data set arranged

18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51

we can calculate the stats using the same technique as above

We get the following values

mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33  

median = 34

mode = 34

range = 51-18 = 33

To find the decrease in mean and median subtract from the first set of values

Answer:

x = 9y

3 = 9 × 5

3 = 45

0 = 45 - 3

0 = 42

Step-by-step explanation:

First of all, write the values of x and y respectively. Then do the DMAS. When there is equal to sign between two numbers then you can bring on number to the other side of equal to sign with the sign changed. Then you get your answer

Answer:

When x= 3, then y= 1/3 and When y= 5, then x= 45

Step-by-step explanation:

3 = 9y

3/9 = y

1/3 = y

and

x = 9 * 5

x = 45

Answer:24 x + 16

Explanation:

We use the distributive rule to handle this situation, which says:

a (b + c) = a b + a c and so we have 8(3x+2)= 24x + 16

Answer:

\(50\% = \frac{50}{100} = \frac{1}{2} \)

Answer: 150.7

Step-by-step explanation:

the second 6 rounds up, since it is over 5. so, that makes the 6 round up to a 7. so, your answer is 150.7

Answer:

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

Answer: $88

Step-by-step explanation:

1. Plug in the given data into the formula.

p = 80

r = 0.1 (represents 10%)

t = 1 year

2. Solve for i based on the formula's values

i = (80)(0.1)(1) = 8

Interest earned is $8 but THIS IS NOT THE FINAL ANSWER!

3. Add i (interest) to p (starting amount)

Elena started with $80, so the interest of $8 is added for a final answer of $88 after one year.

Answer:

Just one (2, -3)

The fourth quadrant is the one with negative numbers on the vertical and horizontal sides. Basically, the bottom left.

Answer:

-16, 10, 16, 25, 43

Step-by-step explanation

when you have something in absolute value bars it's always going to be positive so you would make -16 regular 16; and 10 stays 10; 25 stays 25; -16 stays - 16; and then -43 turns into regular 43

Answer:

-16, 10, 16, 25, 43

Step-by-step explanation:

If it has the bars around it and its a negative number  it turns into a posotive
