Question 3 options:

y=−2x+5

y=−2x−5

y=2x+5

y=2x−5

Answers

Answer:

y = -2x - 5

Step-by-step explanation:

to get the equation into slope-intercept form, you need to get y by itself and to to that you subtract 2x from the left side and -5 stas negative 5 cuz you didnt do anything to it so it would be y = -2x -5

the answer would be y=-2x-5 since we want to get y by itself, we need to subtract 2x on both sides

Step-by-step explanation:

The pharmacist has a 2.8 L bottle of cough syrup. If she fills a bottle that is 1,200 ml, how many ml of cough syrup does the pharmacist have left?

160 ml
400 ml
1,600 ml
4,000 ml

Answers

Answer: 1,600 ml

Step-by-step explanation:

You can arrive at this answer by subtracting the amount of cough syrup used (1,200 ml) from the initial amount in the bottle (2.8 L, which is 2,800 ml).

2,800 ml - 1,200 ml = 1,600 ml

I hope this helps :)

Answer: 1,600 mL

Step-by-step explanation:

1. convert the 1,200 mL to L, which is 1.2 L.

2. Subtract that value from 2.8 L, equaling 1.6 L

3. Convert the 1.6 L back into mL by multiplying by 1000, which is equivalent to 1600 mL.

Ruben digs a hole at the beach that is 4.8 feet deep. Brian uses the sand Ruben digs up to build a sand castle that is 2.5 feet tall.
Which statement correctly compares the depth of Ruben’s hole and height of Brian’s castle?
A. |–4.8| > |2.5|
B. |–4.8| < |2.5|
C. –4.8 > 2.5
D. |–4.8| < 2.5

Answers

Answer: Hope this helps you!

A. |–4.8| > |2.5|

Step-by-step explanation:

When, you compare the distance between stuff, you always compare the absolute value of each thing. And even this equation does not ask for the distance between stuff, it still does require you to compare it with absolute value. The negative sign is only their because they are digging up the ground and not adding to the ground. However, when comparing it, we want to find what is deeper, so we use absolute value making it both positive to compare it fairly. However, if it asked which one was less deep you will use the negative signs. But based on this situation, you don't need to.

how do i figure this out

Answers

the answer would be 2 years

explanation:

$1= $ 30 P = $500$

p= 3% = 0.03

I = PRT

30 = 500 · 0.03 ·t

Substitute

30 = 15t Multiply.

30/15=15/15

divide both sides by 15.

t=2

Answer :- The amount of time is 2 years.

Step-by-step explanation:
To find the time, we use the simple interest
formula; I=PxRxT / 100

Where I is the interest , P is the principal
amount, R is the rate, T is the time in years
and I is the interest.

From the question given,
interest(1) = $30
principal (p) =$500
Rate (R) = 3%
Time (T) is what we are asked too find.

We can now proceed to substitute the
values into the formula; I=PxRxT / 100

$30 = $500×3xT / 100
Multiply 100 to both-side of the equation
$30x100 =$ 1500T/100 ×100
$3000 = $1500 T
Divide both-side of the equation by $1500
to get the value of T
3000/1500= 1500T/1500
2=T
T= 2 years
Therefore the amount of time is 2 years.

Part B: the square root is 5.5

Question 22

Part A: the square root is between 9 and 10.

Part B: the square root is 9.8

Step-by-step explanation:

First of all, it says you can use a calculator! If you do not know how to, let me know in the comments and I can try to help you out! Read the explanation to understand how to do this.

Question 17

Using a calculator, you get 6.48074069… for your decimal.

Rounding it to the nearest tenth, your answer would be 6.5

Now, to find the two consecutive whole numbers the square root is between…

However, there is another way to do this. Remember that 7x7=49. We know that 49 is greater than 42, so let’s see try out a number smaller than 7! 6x6=36. 42 is between 36 and 49, so the square root is between 6 and 7.

Another way to do this is… we know that the decimal is about 6.5, which is between 6 and 7, since those are the two whole numbers before and after that decimal!

Question 18

Using a calculator, you get 9.380833151… for your decimal.

This rounds to 9.4

The whole numbers surrounding this decimal are 9 and 10.

You can also do this by knowing that 9x9, or 9^2, is 81 and 10x10, or 10^2, is 100, and those are the numbers surround 88.

In non-decimal form (simplified radical), your answer can be 2√22.

Question 19

Using a calculator, you get 7.93725393… for your decimal.

This rounds to 7.9

The whole numbers surrounding this decimal are 7 and 8.

You can also do this by knowing that 7x7, or 7^2, is 49 and 8x8, or 8^2, is 64, and those are the numbers surround 63.

In non-decimal form (simplified radical), your answer can be 3√7.

Question 20

Using a calculator, you get 8.66025403… for your decimal.

This rounds to 8.7

The whole numbers surrounding this decimal are 8 and 9.

You can also do this by knowing that 8x8, or 8^2, is 64 and 9x9, or 9^2, is 81, and those are the numbers surround 75.

In non-decimal form (simplified radical), your answer can be 5√3.

Question 21

Using a calculator, you get 5.47722557… for your decimal.

This rounds to 5.5

The whole numbers surrounding this decimal are 5 and 6.

You can also do this by knowing that 5x5, or 5^2, is 25 and 6x6, or 6^2, is 36, and those are the numbers surround 30.

Question 22

Using a calculator, you get 9.84885780… for your decimal.

This rounds to 9.8

The whole numbers surrounding this decimal are 9 and 10.

You can also do this by knowing that 9x9, or 9^2, is 81 and 10x10, or 10^2, is 100, and those are the numbers surround 97.

Note: the symbol "^" means that the number following that symbol is an exponent. So 2^2 is 2 squared, $2^2$, or 2 to the power of 2.

Hope that helps! <3

ok so here ur supposed to figure out which two perfect squares does the square/rational root fall between… an example of a perfect square is square root of 64, since u multiply 8*8 to get 64… another example is square root of 49 since u multiply 7*7.

it’s a pretty easy topic… i’m sure u will get the hang of it :)

Step-by-step explanation:

10.a jar of 70 candies has the following colors: 28 orange, 7 white, 14 brown, and 21 yellow.what is the probability of randomly drawing a candy that is not brown, replacing it, and then drawing a orange candy?

Answers

The total number of candies in the jar is 70, out of which 14 are brown. Therefore, the number of candies that are not brown is 70 - 14 = 56.

To find the probability of drawing a candy that is not brown, replacing it, and then drawing an orange candy, we can use the multiplication rule of probability. According to this rule, the probability of two independent events occurring together is the product of their individual probabilities.

So, the probability of drawing a candy that is not brown on the first draw is 56/70. After replacing the candy, there are still 70 candies in the jar, so the probability of drawing an orange candy on the second draw is 28/70.

Multiplying these probabilities, we get:

(56/70) x (28/70) = 0.16

Therefore, the probability of randomly drawing a candy that is not brown, replacing it, and then drawing an orange candy is 0.16 or 16%.

so…I need help with this! It would be very helpful if you also put the steps so I can write them down in my notebook so I can know how to solve this in future math questions! Will give brainlist to whoever gets this right ☺️

Okay so you plug in 6.7 to M because that’s how far you are.
You are looking for T because it says seconds after.

Answers

Answer:9/3
It’s 9/3 bc all you have yo do it 3x3 then you add the 1 and that equals 9 and then you keep your denominator.

The number of cups as an improper fraction would be 10/3. You can multiply the whole number (3) by the denominator in the fraction (3) to get the number of 1/3 cups in 3 full cups. This would equal 9, or 9/3. And, since you already had a third of a cup in your total, you would add that to the 9/3 cups. So, you would have 1/3 + 9/3 = 10/3 cups

Question: What is the AREA of this shape
(and pls include steps)

Answers

Step-by-step explanation:

first off: write the formula that you would be using, which in my case would be

A = B x H

the B stands for base, and the H stands for height

the base of the shape would be 14.3 in

while the height is the dotted line in the middle (which would be 14.4 in)

to find the answer you would write it like this:

A = B x H = 14.3in x 14.4in

= (conversion to other form of measurement if necessary)

= 205.92 in

(answer may be wrong as it was calculated with calculator app)

One way to approach this would be by splitting up the shape into the bottom part, being a rectangle, and the top part, being a triangle.

The area formulas for each shape are:

rectangle: A=b*h
triangle: A=(1/2)b*h

First, you can start by noticing that the base for both the triangle and rectangle is given, being 14.3 inches.

Next, you can find the height of
