Answer: -44

Step-by-step explanation: First you do add -32 to both sides of the equation, then yo add it all together... Hope this helped :)

Answer:

-12+(-32)= -44

Step-by-step explanation:

negative numbers plus a negative number would result in a smaller negative number. So -12 + -32 would be -44.

Answer:

supplementary

Step-by-step explanation:

angles that are over 90° that over all equal to 180° are supplementary. 156° is over 90° and adding 24° is simple math, meaning 156+24=180

Answer:

for each quart of yogurt, there needs to be 3/4 or 0.75 of a cup of sugar.

we know this since the ratio for cups of sugar to quarts of yogurt is 3:4. which means that for each ONE quart of yogurt there needs to be 3/4 or .75 cups of sugar

Answer:

Yes. This relation is a function.

Step-by-step explanation:

Since there is one value of y for every value of x in (−1,4), this relation is a function.

Step-by-step explanation:

f(-2) = 3(-2) - 12

→ -6 - 12 = -18 ans.

hope this helps you !

What is a Ratio?

A contrast, which exists between two particular numbers, is defined as ratio. Our ratio calculator is developed to compute this contrast and find out the relationship between these numbers.

How to Calculate Ratios

In order to keep numbers in direct relation you should first divide or multiply, which depends on your task, them in the ratio. Therefore, a ratio of 8/6 is an equivalent ratio of 4/3: in that particular ratio calculation, you should just multiply 4, as well as 3, by 2.

(10km - 6.3km)

3.7 km further to walk

Answer:

4/15

Step-by-step explanation:

to find out the portion that is shaded we can do the following:

1 - (1/3 + 2/5)

now we want a common denominator, we can use 15:

15/15 - (5/15 + 6/15)  →  15/15 - 11/15

the answer is 4/15

Answer:

7/8

Step-by-step explanation:

1/4 times 2/2 = 2/8. you would have to do this because the only way you can add fractions is if they have the same denominator. so 2/8 + 5/8= 7/8

Answer:

You ate 7/8 of the chocolate bar.

Step-by-step explanation:

First, we need to change 1/4 and 5/8 so that they have the same denominators (bottom numbers).

There's a common multiple of 8.

What you do to the bottom needs to be done to the top.

1 x 8 = 8

1 x 5 = 5

5/8

Your amount of chocolate stays the same.

4 x 2 = 8

1 x 2 = 2

2/8 is how much the sister had,

Finally, add the two fractions together.

2/8 + 5/8 = 7/8

You ate 7/8 of the chocolate bar.

keeping in mind that in a rhombus the diagonals always meet at right-angles, Check the picture below.

Answer:

The vertex is (0,3), and the zeroes are at -1 and -7

Step-by-step explanation:

Since the function is going upward, the vertex is the minimum value

So the vertex is (0,3)

The zeros of a function are where the function touches the x-axis, or when y is 0.

We can find the zeros by making y (or f(x)) 0.

(x+4)^2-9=0

x^2+8x+16-9=0

x^2+8x+7=0

Factoring

(x+1)(x+7)=0

The zeroes are at -1 and -7.

Explanation:

Suppose we define ...

  a(x) = 2x, for 0 ≤ x ≤ 1

  b(x) = x^2, for 0 ≤ x ≤ 1

Then we have the following:

  c(x) = a(x) +b(x) = 2x +x^2, for 0 ≤ x ≤ 1

  S = max(a(x)) = a(1) = 2

  T = max(b(x)) = b(1) = 1

  R = max(c(x)) = c(1) = 2 +1 = 3

This value of R satisfies S + T = R.

We note that for x=p=1, we have S = a(p), T = b(p), and R = c(p). The first attachment illustrates this case.

Suppose we define ...

  a(x) = x, for 0 ≤ x ≤ 1

  b(x) = 1 -x^2, for 0 ≤ x ≤ 1

  c(x) = a(x) +b(x) = x + 1 -x^2, for 0 ≤ x ≤ 1

Then we have the following:

  S = max(a(x)) = a(1) = 1

  T = max(b(x)) = b(0) = 1

  R = max(c(x)) = c(0.5) = 1.25 ≠ 1 + 1 = 2

This value of R does not satisfy S + T = R.

We note that for p, q, r we have S = a(p), T = b(q), R = c(r) and p≠q≠r. The second attachment illustrates this case.

Answer:

4050 cm²

Step-by-step explanation:

This is a question of scale factors:

The radius of the larger circle is 9× that of the smaller circle;

This is the linear scale factor of the enlargement of the smaller to larger circle;

The scale factor of the area pertains to 2 dimensions so the scale factor will be the square of the linear scale factor, which is:
9² = 81

The area of the larger circle is found by the area of the smaller circle multiplied by this number:
50 × 81 = 4050

Answer:

Part A)The amount of water in the tank is changing at -2/3 gallons per minute.

Part B) it will take 7.5 minutes for the tank to drain completely.

Part C) The water tank was completely full 4.5 minutes before Jada arrived.

Step-by-step explanation:

Information fetching:

Tank of water can hold up-to 10 gallons.

When it is active, a drain empties water from the tank at a constant rate.

7 gallons of water present in the tank when Jade first saw

5 gallons of water left after 3 minutes

Part A) At what rate is the amount of water in the tank changing?

As the gallons were decreased from 7 to 5 in three minutes. It means in three minutes, 2 gallons were decreased.

So, gallons per minute change would be -2/3 gallons per minute. Hence, the amount of water in the tank is changing at -2/3 gallons per minute.

Note: negative sign indicates the number of gallons of water are decreasing.

Part B) How many more minutes will it take for the tank to drain completely.

Let 'm' be the number of minutes will it take for the tank to drain completely.

As,

(2/3 gallons per minute) (m minutes) = 5 gallons

So,

   m = 5 (3/2)

     = 15/2

     = 7.5 minutes

So, it will take 7.5 minutes for the tank to drain completely.

Part C) How many minutes before Jada arrived was the water tank completely full

As tank of water can hold up to 10 gallons. So, the tank of water is full when there is 10 gallons of water. So, this is 3 gallons of water more than the total 7 number of gallons at the time when Jada arrived.

As Jada arrived when the tank had left 7 gallons.

Let 'm' be the number of minutes before Jada arrived when the water tank was completely full.

So,

   (2/3) (m) = 3

   m = 3(3/2) = 9/2

       = 4.5 minutes

So, the water tank was completely full 4.5 minutes before Jada arrived.

Good evening!

In this question, we were asked to solve for the sales tax of the laptop that Youlanda bought.

We were given:
- Cost of laptop: $459

- Sales Tax: 7.5%

In order to find the amount Youlanda paid for the sales tax, we would multiply the cost of the laptop ($459) by the sales tax (0.075):

Calculate:
459 × 0.075 = 34.425

Your answer would be: $34.425

Answer:

152−14−8

Step-by-step explanation:

Answer: The product is: 9r-28

Step-by-step explanation:

(5r+2)(3r-4)

5r x 3r = 15r

5r x -4 = -20r

2 x 3r = 6r

2 x -4 = -8

Put it all together:

15r-20+6r-8

Then simplify:

9r-28
