To finish a project, you need to paint the lateral surfaces of a cube with side length 2.5 inches. Find the area that you need to paint.

Answers

Answer 1

Answer:

[tex]25 in^2[/tex]

Step-by-step explanation:

We want to find the lateral surface area of the cube.

The lateral surface area of a cube is given as:

[tex]A = 4a^2[/tex]

where a = length of side of the cube

Therefore, given that the length of the side of the cube is 2.5 inches, the area you need to paint is:

[tex]A = 4 * 2.5^2\\A = 25 in^2[/tex]

At a particular restaurant, each onion ring has 70 calories and each slider has 200 calories. A combination meal with onion rings and sliders is shown to have 1020 total calories and twice as many onion rings as there are sliders. Write a system of equations that could be used to determine the number of onion rings in the combination meal and the number of sliders in the combination meal. Define the variables that you use to write the system.

Answers

Step-by-step explanation:

r = onion rings amount

s = sliders amount

system of equations

2s = r

r(70) + s(200) = 1020

(for deltamath)

This question is based on the system of equations. Therefore, the system  of equations 2s = r and r(70) + s(200) = 1020 are  that could be used to determine the number of onion rings in the combination meal and the number of sliders in the combination meal.

Given:

At a particular restaurant, each onion ring has 70 calories and each slider has 200 calories. A combination meal with onion rings and sliders is shown to have 1020 total calories and twice as many onion rings as there are sliders.

According to the question,

Let the amount of onion rings be r and the amount of sliders be s.

Now, it is provided in question that, amount of sliders is twice as the onion rings. In mathematically expressed as,

⇒ 2s = r is the first system of equation.

Then, it is also give that, each onion ring has 70 calories and each slider has 200 calories. A combination meal with onion rings and sliders is shown to have 1020 total calories. This representing as,

⇒ r(70) + s(200) = 1020 is the second system of equation.

Therefore, the system  of equations 2s = r and r(70) + s(200) = 1020 are  that could be used to determine the number of onion rings in the combination meal and the number of sliders in the combination meal.

A. 28.26
B. 56.52
C. 63.58
D. 14.13

Answers

Answer:

A

Step-by-step explanation:

The formula for circumference is C = 2[tex]\pi[/tex]r. When plugging in these values, 2 x 3.14 x 4.5 is equal to 28.26.

Circumference of her garden is 28.26 m. So, Option 'A' is the correct answer to the following question.

Circumference based problem:

What information do we have?

Radius of circular garden = 4.5 m

Circumference of her garden = circumference of circle

So,

Circumference of her garden = 2πr

Circumference of her garden = 2(3.14)(4.5)

Circumference of her garden = 28.26 m

Whats the distance between the points (-9,2) and (-4,2)?
A. 5
B. 13
C. 7
D. 2

Answers

Answer:

Distance between the points (-9,2) and (-4,2):

D = sqrt[(-9 - -4)^2 + (2 - 2)^2] = 5

=> Option A is correct

Answer:

B.13

Step-by-step explanation:

In order to solve the distance between two points you need the distance formula which is -> Distance = √  (x1 - x2)^2 + (y1 - y2)^2  

-9 would be x1 and -4 would be x2(so the first numbers of both sets)

Then 2 would be y1 the other 2 would be y2(in this question they both have the same Ys)

You plug in the numbers to the formula.

Which would be:

Distance = √  (-9-4)^2 + (2-2 )^2

Start solving the first part and you will get this:-9-4=-13.Now that the inside is solved,you do the rest,you multiply what you got with the exponent.√(-13)^2=√169.

Then do the second part which is more simple.2-2=0 and when you multiply anything with a 0 is still 0 so when multiplied with the exponent,it stays the same.

You get left with the same answer of √169 and you just have to square root that which is 13.To check your answer,multiple 13*13 which you should get 169.:) Hopefully this was helpful and you understood everything I meant.

What value of a makes the equation true

Answers

Answer:

The correct answer is -2.

Step-by-step explanation:

it is -2 because if you replaced -2 with a you would have -2 minus 1.5 which is -0.5. -0.5 multiplied by 3 gets you -1.5.

Answer:

Step-by-step explanation:

3(a + 1.5) = -1.5

3a + 3*1.5 = -1.5

3a + 4.5 = -1.5

Subtract 4.5 from both sides

3a + 4.5 - 4.5 = -1.5 - 4.5

3a +0 = - 6.0

3a = - 6

Divide both sides by 3

3a/3 = -6/3

a = -2

Which represents the inverse of the function f(x)=4x?

Answers

Answer:

[tex]h(x) = \frac{1}{4}x[/tex]

Step-by-step explanation:

Suppose h is the inverse of f then

f(x) = y ⇔ h(y) = x

f(x) = y ⇔ 4x = y ⇔ x = y/4

and since x = h(y) then h(y) = y/4

then we can write :

[tex]h(x) = \frac{x}{4}[/tex]

Which is a solution to 2x + 1 = 21?

Answers

Answer:

x = 10 is your answer

- Explain -

Step 1: subtract 1 from both sides (subtraction of equality)

which will give us:

2x = 21 - 1

which equals to

2x = 20

Step 2: Divide both sides by 2

which is

2x/2 = 20/2

2/2 = 1 and 20/2 = 10

Therefore the answer is x = 10

44 is equal to 8 times a number minus 4. what is the number?

Answers

Answer:

6

Step-by-step explanation:

Let "a number" = x

44 = 8x - 4

Simplify. Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First add 4 to both sides:

44 (+4) = 8x - 4 (+4)

44 + 4 = 8x

48 = 8x

Isolate the variable, x. Divide 8 from both sides:

(48)/8 = (8x)/8

x = 48/8

x = 6
