Answer:

Interest earned $151.67

Step-by-step explanation:

To find out the amount of interest earned by simple interest.

Deposit = $7,000

Rate of interest = 6.5%

Time = 120 days

To calculate the  interest of simple interest deposit, we use the formula :

I = Prt

I = Interest of the amount

P = Principal amount

r = Rate of interest ( in decimal )

t = time (in year)

Here we have to calculate the interest for 120 days so t would be 120 ÷ 360

I = 7000 × 0.065 × 120 ÷ 360

I = $151.666  ≈  $151.67

Interest earned $151.67

For the two figures to be similar, the missing length must be 30.

<h3 /><h3>What is the missing length?</h3>

For the two figures to be similar, the dimension of each figures must be proportional to each other.

Let the missing length be x.

Hence,

x/25 = 24/20

We cross multiply

x × 20 = 24 × 25

x × 20 = 600

x = 600/20

x = 30

Therefore, for the two figures to be similar, the missing length must be 30.

⦁ Suppose that the number of bacteria in a dish increases by 50% every four hours. there are 64 bacteria initially. write a func
natta225 [31]
Starting with N = N₀·(1+r)^(t/4)
where N is the number of bacteria at t hours, r is the growth rate, and N₀ is the initial number of bacteria
N₀ = 64
r = 50% = 0.5
So the formula is:
N = 64 · (1+0.5)^(t/4)
N = 64·(1.5)^(t/4)

So after 100 hours,
N = 64 · (1.5)²⁵ = 1.6×10⁶
There are 1.6×10⁶ bacteria at 100 hours.

Write the linear equation in Slope intercept form for a slope of 5/2 and a y- point
strojnjashka [21]

Answer:

Y = (5/2)x + 3

Step-by-step explanation:

First, we need to make a couple of things clear:

A <em>linear equation</em> has no powers, meaning it makes a straight line.

<em>Slope-intercept</em> form is y = mx + b, where m is the slope, x is, well, x, and b is the intercept.

y and x will both remain as variables in our final solution.

That all said, now we just need to plug in what we were given.

Y = (5/2)x + 3, since our slope is 5/2 and our intercept is 3.

Hope this helps! Now anything you plug in as x will tell you the y-value on this specific line.

Find the interest earned if you place $76.43 into an account that pays 21.5% simple interest, and leave it in for 3 years.
o-na [289]

A = $125.73

I = A - P = $49.30

hey!

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 21.5%/100 = 0.215 per year.

Solving our equation:

A = 76.43(1 + (0.215 × 3)) = 125.72735

A = $125.73

The total amount accrued, principal plus interest, from simple interest on a principal of $76.43 at a rate of 21.5% per year for 3 years is $125.73.

hope i helped in some way! keep pushing you got this
