Nilda owes $250 to a friend but has been earning $25 per week to catch up and start saving. Karla has saved $200 and has been sa
Nana76 [90]

Answer:

22 and a half weeks

Step-by-step explanation:

We are told that Nilda owes $250 and has been earning $25 per week to catch up and start saving.

Also, Karla has saved $200 and has been saving an extra $5 per week to slowly build her savings.

Let the number of weeks they save for be represented as x.

Therefore, for them to have the same amount of money after x weeks,

25x - 250 = 200 + 5x

The left hand side represents Nilda's situation (250 is being deducted because she owes $250) while the right hand side represents Karla's situation (the 200 is added because she already owns $200).

Solving for x:

25x - 250 = 200 + 5x

Collecting like terms:

25x - 5x = 250 + 200

20x = 450

x = 450 / 20 = 22.5 weeks

Hence, they would both need to save for 22 and a half weeks to have the same amount of money.

The height of the cylinder is 18 meters and the volume of the cylinder is 4,374 cubic meters. What is the area of the base of th
Mrac [35]

Answer:

242.76m^2

Step-by-step explanation:

Given data

Height=18m

Volume=4,374m^3

We know that the expression for the volume of a cylinder is

V=πr^2h

substitute

4374=3.142*r^2*18

4374=56.556*r^2

4374/56.556=r^2

77.339=r^2

r=√77.339

r= 8.79m

But the area of a circle is expressed as

A= πr^2

A=3.142*8.79^2

A=3.142*77.2641

A=242.76m^2

Hence the area of the base is 242.76m^2

Solve each system using substitution.<br> 4. y = 1/x + 4<br> x-y=8
liubo4ka [24]

Answer:

y=\frac{33}{8}

Step-by-step explanation:

y=\frac{1}{8} +4

Use the slope-intercept form to find the slope and y-intercept.

Slope:  

0

y-intercept:  

\frac{33}{8}

To get the answer i used a graph

then i tried just evaluating the equation

Reduce the expression, if possible, by cancelling the common factors.

y=\frac{33}{8}

I got the same answer so i believe this should be your Answer

<u>Hope this helps</u>
