Draw a figure strategy a snail is at t bottom of a 10 ft wall. Each day it climbs up 3 ft. Each night it slides down back 1 ft.

antiseptic1488 [7]

The snail will reach the top of the wall by day 5.

(3ft-1ft)x = 10ft
2x = 10
2x / 2 = 10/2
x = 5 days.

The snail will reach the top of the wall on the 5th day.

11=    d5
10= d5
9=    d4
8=    d4 d5
7= d3
6= d3 d4
5=    d2
4= d2 d3
3= d1
2=    d1 d2
1=
0= d1

3. The simple interest on $6,000 for 4 years is $1,680. *

Nana76 [90]

Substituting the numbers into the simple interest formula, we get
I=. p r t
1,680=(3000)(r)(8). Multiplying
1,680= 24,000r Divide both sides by 24,000
0.07= r
So, the percentage is (0.07)(100)= 7%...

Well, Anita, I am glad to help out... Don't forget to rate my answer:)

Find the area of this semi-circle with diameter, d = 58cm. Give your answer rounded to 2 DP.

Anastasy [175]

Answer:

The area of the semi-circle

A = 1320.37 cm²

Step-by-step explanation:

Explanation:-

Given the diameter of the circle 'd' = 58cm

The radius of the circle 'd' = 2r

$r = \frac{d}{2} = \frac{58}{2} = 29$

The area of the semi-circle

$A = \frac{1}{2} \pi r^{2}$

$A = \frac{1}{2} (3.14) ((29))^{2}$

A = 1320.37 cm²

Kenneth loaned $1,200 to his niece to buy a computer. Two years later, she paid him back the $1,200 along with an interest of $9

insens350 [35]

Answer:

The annual interest rate was 4%

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Loan to Kenneth's niece to buy a computer = US$ 1,200

Duration of the loan = 2 years

Niece paid back to Kenneth = US$ 1,296

Annual interest rate = x%

2. Let's find the annual interest rate after 2 years, using the following formula:

FV = PV * (1 + x)

PV = Loan to Kenneth's niece to buy a computer = US$ 1,200

FV = Niece paid back to Kenneth = US$ 1,296

rate (r) = x

Replacing with the real values:

1,296 = 1,200 * (1 + x)

1.296/1.200 = (1 + x) (Dividing by 1,200 at both sides)

1.08 = 1 + x

1.08 - 1 = x (Subtracting 1 at both sides)

0.08 = x

This is the interest rate for two years, for finding the annual interest rate we divide it by 2, this way:

0.08 / 2 = 0.04 * 100 = 4%
