Clara is growing her hair out and wants it to be no longer than 15 cm but more than 11 cm. Her hair is 7 cm right now and grows
DedPeter [7]

Answer:

16, 32

Step-by-step explanation:

We need to solve for t in this compound inequality. Let's do that!

11 < 7 + 0.25t ≤ 15

4 < 0.25t ≤ 8

16 < t ≤ 32

Therefore, we know that it will take Clara more than 16 weeks and up to and including 32 weeks to grow out her hair.

At a special sale, all pens are sold at one price and all pencils at another price.If 3 pens and 2 pencils are sold for 47 cents
mezya [45]
3 pen + 2 pencil = .47
2 pen + 3 pencil = .38

 2(3pen + 2 pencil = .47)
-3(2pen + 3 pencil = .38)

 6 pen + 4 pencil = .94
-6 pen - 9 pencil = -1.14
            - 5 pencil = -.2
                 pencil = .04

3pen + 2(.04) = .47
3pen + .08 = .47
3 pen + .08 - .08 = .47 -.08
3 pen = .39
pen = .13

Pen = 13 cents and pencil = 4 cents

Jackson deposited $5000 at 3.8% interest compound continuously when he was 18 years old. How much will be in the account when he
weeeeeb [17]

Answer:

$11535.60

Step-by-step explanation:

We have been given that Jackson deposited $5000 at 3.8% interest compound continuously when he was 18 years old.

To find the amount that Jackson will earn when he is 40 years old, we will use compound interest formula.

A=P\cdot e^{rT}

A= Amount after T years.

P= Principal amount.

e= Mathematical constant e.

r= Interest rate (in decimal form).

T=  Time in years.

Let us convert our given interest rate into decimal form.

3.8\text{ percent}=\frac{3.8}{100}=0.038

Upon substituting our given values in above formula we will get,

A=5000\cdot e^{(0.038\times (40-18))}    

A=5000\cdot e^{(0.038\times 22)}

A=5000\cdot e^{0.836}

A=5000\cdot 2.307120015126555      

A=11535.600075632775\approx 11535.60

Therefore, Jackson will have $11535.60 in his account when he is 40 years old.
