Leon had 84 paper clips. He gave 3 4 of them to Joe. Joe gave 2 7 of what he received to Justin. How many paper clips did Justin get?
Please explain it in a statement way!

Answers

Given:

Leon had 84 paper clips.

He gave [tex]\dfrac{3}{4}[/tex] of them to Joe.

Joe gave [tex]\dfrac{2}{7}[/tex] of what he received to Justin.

To find:

How many paper clips did Justin get?

Solution:

Leon had 84 paper clips and he gave [tex]\dfrac{3}{4}[/tex] of them to Joe.

Number of paper clips Joe has = [tex]\dfrac{3}{4}\times 84[/tex]

                                                    = [tex]63[/tex]

Joe gave [tex]\dfrac{2}{7}[/tex] of what he received to Justin.

Number of paper clips Justin has = [tex]\dfrac{2}{7}\times 63[/tex]

                                                       = [tex]18[/tex]

Therefore, Justin has 18 paper clips.

Step-by-step explanation:

$10.75-$8.25=$2.50

$3.50-$2.25=$1.25

$2.50+$1.25=$3.75

As only one-time fee, we cancel out it, then only add on the per-month fee, which is $1.25 every month.

Answer:

H = .298

Step-by-step explanation:

First lets plug in 1.5 for R and  16 for Surface area to get the following

2*pi*1.5^2+2*pi*h = 16  We are solving for H or height

Lets simplify this out a bit to get

16 = 14.13+6.28h

Subtract 14.13 from both sides

1.87 = 6.28h

h= .298

To check our answer lets plug the height into the equation

2*pi*1.5^2+2*pi*.298 = 16

Yes the height or H is .298

To check your answer just plug back what you got before into the equation

(32.5:100)*250 =

(32.5*250):100 =

8125:100 = 81.25

Answer:

1) 9.9

2) 81.25

Step-by-step explanation:

1)

22% = 0.22

45(0.22) = 9.9

2)

32.5% = 0.325

250(0.325) = 81.25

There are 360 seals. Of them are 9/20 are pups. The rest are adult seals . How many pups are the beach .

Answers

Answer:

162 pups are on the beach

Step-by-step explanation:

9/20 of 360

The key word "of" tells us to multiply

Variable x = number of pups

9/20 × x/360

Cross multiply

9 × 360 = 20 × x

3,240 = 20x

Divide both sides by 20

162 = x

Check our work:

9/20 = 162/360

Cross multiply

9 × 360 = 20 × 162

3,240 = 3,240

•A is correct because if you drew the linear line for function A, it would intercept with B on point (1,4) which is also a point for function B.
•B is incorrect because y-intercept in A=1 and B=3, that’s not in common
•C is incorrect because the slope in A=1/3 and B=1, that’s not in common

Applying the formula given above

N=Noe^rt

No = 2.62 million

r = 3.5% = 0.035

t = 2010 - 2004 = 6 years

N = 2.62 × e^6 × 0.035
