7 0

Answer:

0.0000302

Step-by-step explanation:

When 10 is to the power of a negative number, "move" the decimal dot left.

10⁻⁵ means to "move" the decimal 5 times to the left.

1. Write a bunch of extra 0's for the coefficient. (The coefficient is 3.02).

0000003 . 02

2. Count 5 place values over.

00←0←0←0←0←3 . 02

3. Put the decimal behind the digit.

00 . 0000302

4. Get rid of the 0s that you don't need. You only need one 0 left of the decimal.

0.0000302           <= Final answer

Parents wish to have 160,000 available for a​ child's education. If the child is now 8 years​ old, how much money must be set as
Ray Of Light [21]

Answer:

$118,791.2985

Step-by-step explanation:

Given that,

A = 160,000

T = 18 - 8 = 10 years

Rate = 3%

since it is semi annual, n = 2

A = P ( 1 + R/2) ∧ 2T

160000 = P ( 1 + 3/2*100) ∧ 2 * 10

160000 = P ( 1 + 3/200) ∧20

160000 = P( 1 + 0.015) ∧20

160000 = P(1.015)∧20

P= 160000/ (1.015)∧20

P = 160000/ 1.3469

= $118,791.2985

Any help please I appreciate it thank you
Natali5045456 [20]

Answer:

20 feet

Step-by-step explanation:

Parimeter is how far you would walk if you made a lap around the shape, walking on the edge lines like a balance beam.

To find perimeter, we need to add up all the sides.

Because it's a square each side has the same length.

There are 4 sides.

5 x 4 = 20

or 5 + 5 + 5 + 5 = 20

The perimeter is 20 feet
