Jane is is charge of making a banner for the basketball game this Saturday. She measures how long the banner is before painting

RSB [31]

Answer:

The measurement which Jane finds to be 10 meters is the length of the banner.

Step-by-step explanation:

The measurement of 10 meters which Jane found after measuring how long the banner is before painting is the LENGTH of the banner.

This is clear from the unit of what she finds (meters). It only indicates the measurement of one part of the banner, even though a banner has two parts, the length and width.

It is possible to find the AREA, or PERIMETER, or LENGTH.

But what she finds is the LENGTH of the banner. If it was Area or Perimeter, the unit would have been square meters.

A sum of $9, 000 paid into a bank account for two months (61 days) to attract simple interest will produce $9, 020 at the and of

Juliette [100K]

Answer:

Rate of interest will be 1.33 %

Return on this investment = $=\frac{9020-9000}{9000}=0.222$ %

Step-by-step explanation:

We have given principle amount P = $9000

Time = 61 days = $\frac{61}{365}=0.167\ years$

We have to find the rate of interest

Total amount produce at the end of term = $9020

So interest = $9020 - $9000 = $20

We know that simple interest $=\frac{principle\ amount\times rate\times\ time}{100}$

$20=\frac{9000\times rate\times\\ 0.167}{100}$

$rate=1.33$ %

Return on this investment = $=\frac{9020-9000}{9000}=0.222$ %

Which measure is equivalent to 2.5<br>A) 2.5 mL<br>B) 250 mL<br>C) 2500 mL<br>D) 25000 mL

Molodets [167]

Answer: option C) 2,500 ml (under the assumptions shown below)
Explanation:

This is a conversion of units, but you missed the unit of the question.

What is it?

It seems it should be 2.5 liters.

So, I am going to explain you how to deal with this problem, assuming you have to find the measure equivalent to 2.5 liters.

All the choices are in mililiters (ml).

Then, you use the conversion factor 1 liter = 1000 ml

With that you do:

2.5 liter × 1000 ml / liter = 2,500 ml

And that is the choice C).

A company distributes college logo sweatshirts and sells them for $50 each. The total cost function is linear, and the total cos

mart [117]

Answer:

The total revenue equation is TR=50Q

The total cost equation TC=2304+14Q

Equilibrium quantity is 64

Step-by-step explanation:

The total cost function can be written TC=a+bQ, where TC is the total cost ,a fixed cost ,b is the variable cost per unit and Q the quantity produced

Revenue function can be given TR=P*Q, where TR is total revenue,P is the price per unit and Q quantity sold

since P is $50

TR=50P

when TC=$3564,

3564=a+90Q equation 1

when TC=$5944

5944=a+260bequation 2

Solving simultaneously,we subtract equation 1 from 2

5944=a+260b

3564=a+90b

2380=170b

b=2380/170

b=$14

We substitute for b in any of the equations

3564=a+(14*90)

3564=a+1260

a=3564-1260

a=2304

Hence the total cost equation is

TC=2304+14Q

At equilibrium TC =TR

50P=2304+14Q

50P-14Q=2304

36Q=2304

Q=64
