Answer: They sold 104 sodas and 52 hotdogs

Step-by-step explanation: If we represent sodas as x and hotdogs as y then x+y=156. There is twice as many sodas as hotdogs so x=2y. We can then substitute x for 2y so the equation would be 2y+y=156 or 3y=156. We divide both by three and get y=52 we plug that back in to the equation x=2y and we get x=104. We then check to make sure it is correct and get 104+52=156 and 104/2=52. Hope this helps.

Answer:

Domain: 0 ≤ x ≤ 22

Step-by-step explanation:

Given

f(x) = 2.5x

Required

Determine the domain of the function

From the question, we understand that the size of the bucket is 55 quarts

This means the maximum of the range is 55.

In other words, the maximum value of f(x) is 55

Substitute 55 for f(x) in f(x) = 2.5x

55 = 2.5x

2.5x = 55

Make x the subject

x = 55/2.5

x = 22

Also, we understand that x represents time and it's impossible to have a negative time.

So, the minimum value x can get is

x = 0

The domain can then be represented as:

Minimum ≤ x ≤ Maximum

This gives:

0 ≤ x ≤ 22

Answer:

Domain: 0 ≤ x ≤ 22

Answer:

1.5 cups of butter

Step-by-step explanation:

3 : 1 <- this is our ratio

divide by 2

1.5 : 0.5 is our new ratio

equation: 1.5 * ? = 4

? = 3 cups of sugar

multiply the ratio by 3

1.5 : 0.5 = 4 : 1.5

we need 1.5 cups of butter for 4.5 cups of sugar

Answer:

8%

Step-by-step explanation:

To find the percent, divide 16 by 200, then multiply it by 100.

(16 / 200) x 100

0.08 x 100

= 8

So, 16 is 8% of 200

Answer:

-12

Step-by-step explanation:

first 4 times 2 is 8

so-   8-4(-5)(-1)

next negative four times negative 5 positive  20

so-  8+20(-1)

20 times negative 1 is -20 plus 8 is -12.

Answer:

Step-by-step explanation:

area of a triangle = 1/2  x  base  x  height

                            = 1/2  x 5  x 8

                            = 20 yd²

The area of the figure is 20 yd²

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

Given that, a figure of triangle with height = 8 yd and base = 5 yd

We know that,

The area of a triangle = 1/2  x  base  x  height

= 1/2  x 5  x 8

= 20 yd²

Hence, The area of the figure is 20 yd²

Answer:

the answer is (0,-1) is a point on the line or maybe not

The rules of operations states that we deal with parentheses first. So, inside the parentheses, we have, 2 times 3. Multiply that. That gives us 6. So now, the equation looks like this:

(6)^2 + 5^2

Now we have to work with the exponents. So, square both numbers.

(6)^2 = 36

5^2 = 25

Now we have:

36 + 25

Now we add. 36 + 25 = 61

61 is your answer.
