☆ Emily has $16 more

Step-by-step explanation:

FOR JAXON:

You want to calculate the interest on $600 at 2.5% interest per year after 3 year(s).

The formula we'll use for this is the simple interest formula, or:

Where:

P is the principal amount, $600.00.

r is the interest rate, 2.5% per year, or in decimal form, 2.5/100=0.025.

t is the time involved, 3....year(s) time periods.

So, t is 3....year time periods.

To find the simple interest, we multiply 600 × 0.025 × 3 to get that:

The interest is: $45.00

Usually now, the interest is added onto the principal to figure some new amount after 3 year(s),

or 600.00 + 45.00 = 645.00.

Jaxon will have $645 after he closes his account.

FOR EMILY

You want to calculate the interest on $600 at 5.1% interest per year after 2 year(s).

The formula we'll use for this is the simple interest formula, or:

Where:

P is the principal amount, $600.00.

r is the interest rate, 5.1% per year, or in decimal form, 5.1/100=0.051.

t is the time involved, 2....year(s) time periods.

So, t is 2....year time periods.

To find the simple interest, we multiply 600 × 0.051 × 2 to get that:

The interest is: $61.20

Usually now, the interest is added onto the principal to figure some new amount after 2 year(s),

or 600.00 + 61.20 = 661.20.

Emily will have $661 when she closes her account.

☆ Therefore, Emily will have $16 more than Jaxon.

I would really appreciate if you would mark me brainliest!!

I hope you have a good day!!! ☆ :D

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AC =16 and DC=5 what is the length of BC in the simplest ra

Nana76 [90]

The length of BC is $4 \sqrt{5}$ .

Solution:

Given ABC is a right triangle.

AC is the hypotenuse and BD is the altitude.

AB and BC are legs of the triangle ABC.

AC = 16 and DC = 5

Leg rule of geometric mean theorem:

$\frac{\text { hypotenuse }}{\text { leg }}=\frac{\text { leg }}{\text { part }}$

$\Rightarrow \frac{AC}{BC}=\frac{BC}{DC}$

$\Rightarrow \frac{16}{x}=\frac{x}{5}$

Do cross multiplication.

$\Rightarrow 16\times 5 = x\times x$

$\Rightarrow 80= x^2$

$\Rightarrow 16\times 5= x^2$

Taking square root on both sides.

$\Rightarrow \sqrt{16\times 5} = \sqrt{x^2}$

$\Rightarrow \sqrt{4^2\times 5} = \sqrt{x^2}$

square and square roots get canceled, we get

$\Rightarrow 4\sqrt{ 5} = x$

The length of BC is $4 \sqrt{5}$ .

Marco sews pillow and comforter sets. Each set has 2 pillows and 1 comforter. He uses 0.75 yards of material for each pillow and

Aliun [14]

Answer:

He would need 58 yards of material.

Step-by-step explanation:

If there are 4 sets of pillows and comfoters, that means there are 8 pillows and 4 comfoters.

If each pillow uses 0.75 yards of material, 8x0.75= 6

If each comfoters uses 13 yards of material, 4x13= 52

6+52= 58 yards of material.
