Ryan's take-home pay is $2,500 each month. The amount for gas is $125. Calculate the percentage Ryan uses on gas from his take-home pay. please help!! O^O

Answers

Answer: 5%

Step-by-step explanation:

Since Ryan's take-home pay is $2,500 each month and the amount for gas is $125.

The percentage that Ryan uses on gas from his take-home pay will be:

= Amount used on gas / Take home pay × 100

= 125/2500 × 100

= 1/20 × 100

= 5%

He used 5% on gas.

can someone please double check this for me?​

Answers

Answer:

False

True

False

True

Step-by-step explanation:

The 4th option should be correct because the y-intercept on A is greater than the one in B,

A: y = -1/3x + 0 (usually when the y-intercept ain't appearing it means it's 0).

B: y = -1/3 - 2

As we know 0 is greater than -2 because it's closer to being a positive number, so 0 is not positive or negative; 0 is greater than any negative number but smaller than any positive numer so,

0 > -2.

Therefore the last option is true.

Hi there!

[tex]\large\boxed{h = \frac{15x}{y}}[/tex]

Recall the volume of a pyramid is:

V = 1/3(bh)

We are given the volume and side length of the base. Find the area of the base:

A = s²

A = (5xy²)² = 25x²y⁴

Plug in the solved for base:

125x³y³ = 1/3(25x²y⁴)h

To isolate for h, begin by multiplying both sides by 3:

375x³y³ = (25x²y⁴)h

Divide both sides by 25x²y⁴. Use the following exponent property:

xᵃ / xᵇ = xᵃ⁻ᵇ

Thus:

375x³y³ / 25x²4⁴ = 15x/y.

The height must be equal to:

A triangle has angle measures of 47 degrees and 92 degrees. What is the measure of the third angle?

Answers

Answer:

The missing angle is 41 degrees

Step-by-step explanation:

First of all, a triangle is measured at 180 degrees in total

To find the missing measurement for the third angle, add the 47 and 92 degrees together which would equal 139 degrees.

47+92=139 degrees

Next just subtract 139 from 180 to get your answer.

180-139=41 degrees

The answer is 41 degrees

The total surface area of a cylinder with height 5 in. is given by the function g(x) = 2πx2 + 10πx, where x is the radius, and the function f(x) = 10πx gives the surface area of the side of the cylinder. Which combined function gives the total surface area of the two bases of the cylinder? A. f + g B. f – g C. g – f D. f · g

Answers

Answer:

C. g - f

Step-by-step explanation:

Total surface area of a cylinder with height 5 is:

A = 2πrh + 2πr² = 10πr + 2πr²

If we substitute r with x, we get:

g(x) - full surface areaf(x) - surface area

Total surface area of two bases:

g - f = 2πx² + 10πx - 10πx = 2πx²
