Given the formula l = prt, where l = interest earned, P is the principal invested and r is the interest rate. If $245 is the principle invested at an interest rate of 3%, and Paul earned 69.80 interest, how long, t, (in years) was the money invested for?

Answers

Answer 1

Answer:

t= 9.49 years which can be estimated to 9 years

Step-by-step explanation:

Given the formula l = prt,

Where P is the principal=$245

r is the interest rate.=3%,

l = interest earned=$69.80

l = prt

Therefore time, t= I/ pr

t= 69.80/ 245 x 3%

t=69.80/ 245 x 0.03

t= 9.49 years which can be estimated to 9 years

-2x/3 + 11 = 14 please help me its not letting me put stuff I want

Answers

Answer:

x = -4 1/2

Step-by-step explanation:

-2x/3 + 11 = 14

subtract 11 from each side of the equation:

-2x/3 = 3

multiply both sides by 3:

-2x = 9

divide both sides by -2:

x = -4 1/2

HELP ME ASAP BRAINLY :)) How many sides does a polygon have if its total interior angle sum is 4 times its total exterior angle sum?

Answers

Answer:

Step-by-step explanation:

If you are given the interior angle, just subtract that from 180 to get the exterior angle and then use the number of sides = 360 / exterior angle to find the number of sides. it's much easier. the number of sides is equal to 10. the sum of the interior angles is equal to 10 * 144 = 1440 degrees.
10 x 144 so that would be 1440

Answers

Answer:

x = 7

Step-by-step explanation:

Given

3x - 5 = 16 ( add 5 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7

Answer: X= 7

Explanation:
(you need to get x by its self)

Step 1- add the (-5) over to the 16

Because to get rid of a negative or minus sign you need to do the opposite which is addition.

You’ll get: 3x=21

Step 2- divide the 3 off from 21
Because the ‘3x’ is acting as multiplication, and the opposite of multiplication is division

You’ll get: X=21/3
Which is X=7

A designer builders a model of a bicycle the finished model is exactly the same as the original but smaller. The scale factor is 2:15 (A) ratio of height ☑️:☑️ (B)surface area ☑️:☑️ (C)volume ☑️:☑️

Answers

Answer:

a) The ratio of height is 2:15

b) The ratio of surface area is 4:225

c) The ratio of volume is 8:3375

Step-by-step explanation:

The scale factor of model to original is 2 :15

Please remember the concept, when scale factor is a:b

Then ratio of sides would be same a:b

The ratio of surface area is [tex]a^{2} :b^{2}[/tex]

The volume is [tex]a^{3} :b^{3}[/tex]

According to the concept,

The ratio of height is 2:15

The ratio of surface area is [tex]2^{2} :15^{2}[/tex] =4:225

The ratio of volume is [tex]2^{3} :15^{3}[/tex] =8 :3375.
