Find a measure of angle 8.

Answers

Answer 1

Answer: Angle 7 and 5 are vertical angles, so they're equal. Angles 7 and 8 are supplementary, so they have to add up to 180. 2x + 15 + 3x = 180 Solve for x, then plug it into the expression for angle 7 to get you answer

A cylinder is full at 471 cm³ and has a radius of 5 cm. It currently contains 314 cm³ of water.What is the difference between the height of the water in the full cylinder and the height when 314 cm³ of water remains in the cylinder?”

Use 3.14 to approximate pi.

Answers

The answer is 2 cm

Step 1. Calculate the height of full cylinder (h1 = ?)
Step 2. Calculate the height of cylinder that contains 314 cm³ of water (h2 = ?)
Step 3. Find the difference between the height of the water in the full cylinder and the height when 314 cm³ of water (h1 - h2 = ?)

The volume (V) of the cylinder with radius r and height h is:
V = π * r² * h
So, h = V / (π * r²)

Step 1.
h1 = ?

V1 = 471 cm³
r = 5 cm
π = 3.14

h1 = V1 / (π * r²)
h1 = 471 / (3.14 * 5²)
h1 = 471 / (3.14 * 25)
h1 = 471 / 78.5
h1 = 6 cm

Step 2.
h2 = ?

V2 = 314 cm³
r = 5 cm
π = 3.14

h2 = V2 / (π * r²)
h2 = 314 / (3.14 * 5²)
h2 = 314 / (3.14 * 25)
h2 = 314 / 78.5
h2 = 4 cm

Step 3.
h1 - h2 = 6 - 4 = 2 cm

Answer: The answer is 2

Step-by-step explanation:

Luis made 80% of what he made last week.If he made 72$ this week,how much did he make last week

Answers

Let

x--------> the amount in dollars that Luis make last week

we know that

$80\% =(80)/(100)=0.80$

$0.80x=72\$$ ------> equation that represent the situation

solve for x

Divide by $0.80$ both sides

$0.80x/0.80=72\$/0.80$

$x=72\$/0.80$

$x=90\$$

therefore

the answer is

$90\$$

Answer:

He made $90 last week

Step-by-step explanation:

Since we are told that Louis made 80% of what he made last week and since Louise made $72 this week, to get how much he made this week, we will follow the step below:

let x be the amount he made last week

80% of x = $72

80% × x = $72

$(80x)/(100)$ = $72

the fraction 80x/100 can be reduced to 4x/5. Hence;

$(4x)/(5)$ = $72

Multiply both-side of the equation by 5

$(4x)/(5)$ x 5 = $72 x 5

4x =360

Divide both-side of the equation by 4 to get the value of x

$(4x)/(4) = (360)/(4)$

On the left-hand side of the equation 4 will cancel-out 4 while on the right-hand side of the equation 360 will be divided by 4

x = $90

Therefore he made $90 last week

Nine less than six times a number is -15

Answers

The equation for the given phrase is 6x-9=-15 and the solution for the obtained equation is -1.

The given phrase is "nine less than six times a number is -15."

Let the unknown number be x.

Here, six times a number = 6x

The product is less than 9, that is

6x-9

Nine less than six times a number is -15, so the equation is

6x-9=-15

Now, the solution is

6x=-15+9

6x=-6

x=-6/6

x=-1

Therefore, the equation for the given phrase is 6x-9=-15 and the solution for the obtained equation is -1.

Hello!

6 - 9 × y = -15

When "less than" is used you switch the number before it the number after it. While it seems like it would be 9 -6, its actually 6-9

6 - 9 is -3, you can multiply 3 by 5, to get 15. So your answer would be 5

Hope this helps!

A recipe for 8 servinfs of pudding clls for 2 cups of milk.How many gallons of milk are needed to make enough pudding for 64 servings

Answers

In order to solve this, we first need to know what the ratio of servings of pudding to cups of milk is. We can see that 8 servings of pudding requires 2 cups of milk, so the ratio is 8/2, which can be reduced to 4/1. This means that for every 4 servings of pudding, we will be adding 1 cup of milk. So all we need to do to find out how many cups would be needed for 64 servings of pudding, we simply need to divide by 4.

64 / 4 = 16

So for 64 servings of pudding, we will need 16 cups of milk. But that's not what the question wants to know, it wants to know how many gallons of milk it would need.

In order to find that out, we have to know how many cups there are in one gallon. There are 2 cups in one pint, there are 2 pints in a quart, and there are 4 quarts in a gallon, so we just have to multiply those numbers, and we get 4 * 2 * 2 = 8 * 2 = 16

There are 16 cups in one gallon, therefore, 64 servings of pudding will require 1 gallon of milk.
Hope that helped! =)
