Jordan got an 81% .

how to figure out mean: 66,79,81,82 .

Add 79 and 81, which is 160/2=80%
You'll so be able to figure this out, because Jordans percent grade has to be lower than 82, and higher than 79. Therefore, you'll have to come up with a number that is higher than 79, but lower than 81. and first you have to come up with a number that will equal to 160 when you add it by 79. so, 160-79 = 81% which is also known as Jordan's grade. therefore the answer is, 81% dot Hope this helped!!

The answer would be 93% because first we need to do the reverse of how to find the mean... 80 * 4 = 320 and so we just have to subtract the grades from 320... 320 - 79 - 66 - 82 = 93... Thus Jordan's grade was 93

Taylor plans to use $2100 to open a savings account with an annual interest rate of 1.85%. How much more interest will he earn o

Ymorist [56]

Taylor will earn $21 more in compounded interest than in simple interest.

Given:
Principal = 2100
interest rate = 1.85%
term = 8 years

Simple Interest = Principal * interest rate * term
= 2100 * 1.85% * 8
= 310.80

Compounded Interest = Principal * (1+r)^t
= 2100 * 1.0185⁸
= 2100 * 1.158
= 2431.80

Interest from Compounded Interest : 2431.80 - 2100 = 331.80

Simple Interest = 310.80
Compounded Interest = 331.80

331.80 - 310.80 = 21

Answer:

The height of the other book is 2 3/4 inches.

Step-by-step explanation:

From the information,we get:

Two stacks of books together are = 7 1/2 inches tall.

One stack is given,that is = 4 3/4 inches.

To Find:

The height of the other.

Solution:

Let us assume that the other height of the book be x.

Then the equation will be:

$4\cfrac{3}{4} + x = 7\cfrac{1}{2}$

Solve for x to get the other book's height.

Convert the mixed fractions to fractions:

$\implies \: \cfrac{19}{4 } + x = \cfrac{15}{2}$

Subtract 19/4 from both sides:

$\implies \: x + \cfrac{19}{4} - \cfrac{19}{4} = \cfrac{15}{2} - \cfrac{19}{4}$

$\implies \: x = \cfrac{11}{4} =\boxed{ 2 \cfrac{3}{4} \rm \: inches}$

Hence, we can conclude that:

The height of the other book is 2 3/4 inches.

Maddy is carrying a 555 liter jug of sports drink that weighs 7.5\text{ kg}7.5 kg7, point, 5, start text, space, k, g, end text.

Lelu [443]

Answer:

w/2 = 7.5/5

3kg

Step-by-step explanation:

Remaining question below:

Which proportion could Maddy use to model this situation?

a. w/2 = 7.5/5

b. w/7.5 = 5/2

Solve the proportion to determine the weight of a 2 liter jug.

_____kg

5 liters jug of sport drink weighs 7.5kg

2 liters jug of sport drink will weigh x kg

Find w

Ratio of weight to volume

7.5kg : 5liters=7.5/5

wkg : 2 liters=w/2

Equates the ratio

7.5 / 5 = w / 2

Cross product

7.5*2=5*w

15=5w

Divide both sides by 5

3=w

w=3kg

Therefore, weight of the 2liters jug of sport drink is 3kg
