Jerry planted a pine tree that was 5 feet tall and a maple tree that was 10 feet tall. The pine tree grew 3 feet taller per year

stich3 [128]

The initial length of the pine tree=5 feet.

Groth rate of pine tree =3 feet/year.

The initial length of the pine tree =10 feet.

Groth rate of the maple tree =2 feet/year.

After x years, the height of the pine tree= 5+3x feet and

after x years, the height of the maple tree= 10+2x feet.

The inequality for which, after x year, the pine tree is taller than the maple tree is

$5+3x>10+2x$

$\Rightarrow x>5$ .

The inequality for which, the pine tree is at least as tall as the maple tree is $5+3x\geq10+2x$ .

$\Rightarrow x\geq 5$ .

Again, after 3x years, the height of the pine tree= 5+3(3x)=5+9x feet and

after 2x years, the height of the maple tree= 10+2(2x)=10+4x feet.

The inequality for which, after 3x years, the pine tree is taller than the maple tree was after 2x years is

$5+9x>10+4x$

$\Rightarrow 5x>5$

$\Rightarrow x>1.$

The inequality for which, the pine tree is at least as tall as the maple tree is $5+9x\geq10+4x$ .

$\Rightarrow 5x\geq5$

$\Rightarrow x\geq 1.$

Gavin deposited $516 into a special savings account that earns 6.25% interest after 1 year. If Gavin doesn’t deposit any money i

tiny-mole [99]

Answer:

The amount of interest earned after a year is $32.25

Step-by-step explanation:

In this question, we are asked to calculate the amount of interest generated by depositing a sum into an account.

To calculate the interest earned, we use the simple interest formula.

Mathematically;

I = PRT/100

where I is the interest earned

R is the rate which is 6.25% according to the question

T is the time taken which is 1 year

P is the amount of money deposited also know. as the principal which is $516

Plugging these values we have

I = (516 * 6.25 * 1)/100 = $32.25
