Johnny earns $5 per day delivering newspapers. What equation shows how much money m he earns delivering papers for d days?

jeyben [28]

Hello there,

Your correct answer would be C.) m=5d.

The reason is so because 5 and d are going to be multiplied and so sence they would be multiplied this mean's that you will see how much money he earned in (m) days.

Correct answer would be "C.) m=5d"

Hope this helps!

Easy question

Leviafan [203]

$\dfrac{\mathrm dy}{\mathrm dt}=ky\iff\dfrac{\mathrm dy}y=k\,\mathrm dt$

Integrating both sides, we get

$\ln|y|=kt+C$
$\implies y=e^{kt+C}=e^{kt}e^C=Ce^{kt}$

When $t=0$ , we have $y=10000$ , so that

$10000=Ce^{0k}\implies C=10000$

When $t=4$ , we have $y=8000$ , which means

$8000=10000e^{4k}\implies k=\dfrac14\ln\dfrac{8000}{10000}\approx-0.0558$

What is this I have been on it fourever

Yuki888 [10]

Answer:

$\frac{3}{4}$ = $\frac{9}{12}$

Step-by-step explanation:

The values are in proportion if the right side is a multiple of the left side

Consider

$\frac{3}{4}$ × $\frac{3}{3}$

= $\frac{3(3)}{4(3)}$

= $\frac{9}{12}$

Thus $\frac{3}{4}$ and $\frac{9}{12}$ are in proportion

This does not happen for any of the other three.

Evaluate the expression

ruslelena [56]

Answer: 85

Step-by-step explanation:

To solve this problem, we want to use the order of operations, or PEMDAS.

Parenthesis

Exponent

Multiply

Divide

Add

Subtract

To be more specific, you evaluate the expression in the order from top to bottom. To clarify, it is multiply OR divide, depending on which comes first, left to right. This also applies to add OR subtract.

------------------------------------------------------------------------------------------------------------

20÷(5-3)+5²(3) [solve parenthesis]

20÷(2)+5²(3) [solve exponent]

20÷2+25(3) [solve multiply or divide, left to right]

10+75 [solve add or subtract]

85

GIVING BRAINLIESST PPL

You need to split the shape into simpler shapes so you would get a rectangular prism and a triangular prism finding the volume is pretty straightforward the formula is

Volume of a triangular prism = area of base triangle × height

The formula for finding the volume of a rectangular prism is the following: Volume = Length * Height * Width, or V = L * H * W.
After solving for this you would just have to add the 2 shapes volume together tie get the volume of the composite figure
Finding the surface area is also pretty simple since it would only require you to know the formulas

S = 2(lw + lh + wh) to find the surface area of a rectangle or prism

A=12bh is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height.
And by adding the two surface areas of the shapes you can get the surface area of the composite figure but remember to subtract the top face of the rectangular prism and the bottom face of the triangular prism
Hope this helps <3
