Step2247 [10]

Answer:

F

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year,

then, solving our equation

I = 5500 × 0.06 × 2.5 = 825

I = $ 825.00

The simple interest accumulated

on a principal of $ 5,500.00

at a rate of 6% per year

for 2.5 years is $ 825.00.

5 is what percentage of 25? I’ll give brainliest:)
lord [1]

Hi there! :)

<h2>20%</h2><h2></h2>

To solve, we can simply divide and multiply by 100 to solve for the percentage:

5 / 25     = 5 ÷ 25 = 1/5 or 0.20

Multiply the decimal by 100 to solve for the percentage:

0.20 × 100 = 20%

A bicycle wheel with the diameter 70cm is making 25 revolutions while travelling. Find the distance covered by the bicycle
Diano4ka-milaya [45]

Answer: 5500cm.

Step-by-step explanation:  

A revolution  corresponds to circumference of the bicycle wheel.

The radius of the circle = 70/2 since two radii makes a diameter.

Therefore r = 35cm

Circumference of a circle =  2πr or πd where π = 3.142 or 22/7

      We now have              =  2 x 22/7 x 35

Therefore 0ne revolution   = 220cm.

Therefore, the distance traveled by making 25 revolution

                                            = 220 x 25

                                            = 22000/4

                                            = 5500cm.

The number of bacteria on a piece of toast triples every
Illusion [34]

Answer:

You begin with 1 bacteria, and after 1 hour it has tripled so you now have 1 x 3=3.

Next hour, it triples again so you now have 1 x 3 x 3=9

You can see the pattern shows that the number of bacteria is multiplying every hour by a factor of 3. An exponent denotes how many times we are multiplying a number by itself, for example: 34 means we are multiplying the number 3 a total of 4 times (3 x 3 x 3 x 3).

Therefore the question is requiring us to triple the number of bacteria every hour for 24 hours, which means we are multiplying by 3 a total of 24 times. This gives us:

n x 324 where n is the number of bacteria you begin with.

Since you begin with 1 bacteria, the solution is 1 x 3 to the power 24 and u will get ur answer
