alexdok [17]

Instead of subtracting 6 from 12 then dividing they added 6 to 12 & ended up with 18. 18 by 2 is 9.

I wish to have $10,000 at the end of 8 yers in a bank offering a simple interest rate of 7.5% per year. How much should I deposi

kolezko [41]

Answer:

You have to invest $6,250

Step-by-step explanation:

very simple applying the simple interest formula which is

$A = P (1 + rt)$

Given data

A, final amount = $10,000

P, initial principal balance= ?

r, annual interest rate = 7.5%

t, time (in years)= 8 years

we can substitute our given data to find the principal needed.

$10000= P(1+0.075*8)\\\10000= P(1.6)\\\$

Divide both sides by 1.6 we have

$P= \frac{10000}{1.6} \\\P= 6250$

P= $6,250

Explain how to find the surface area of a can of fruit with a height of 80 mm and a diameter of 60 mm. Give the area in your exp

8_murik_8 [283]

Answer:

$S=6600\pi \text{ mm}^2$

$S\approx 20724 \text{ mm}^2$

Step-by-step explanation:

A can of fruit is geometrically a cylinder.

We are talking about the surface area of a cylinder:

$S=2\pi rh+2\pi r^2$

$\pi \approx 3.14$

$r: \text{radius}$

$h: \text{height}$

Factoring, we have:

$S=2\pi r (h+r)$

Calculating the surface area of the can of fruit:

$S=2\pi (30) (80+30)$

$S=2\pi (30) (110)$

$S=6600\pi$

$S\approx 20724 \text{ mm}^2$

4m≥m+9>-9+4m Please answer urgent

Vsevolod [243]

Next time, please include the instructions.

This inequality could be broken into two parts:

4m $\geq$ m + 9 AND m + 9 > -9 + 4m

Focus first on the inequality m + 9 > -9 + 4m. subtract m from both sides, obtaining:

9 > -9 + 3m. Next, add 9 to both sides, obtaining: 18>3m, or m<6

Last step: Determine whether the inequality 4m≥m+9 is true if m<6.
