Step-by-step explanation:
304780 - 167344 = 137436
167344 + 137436 = 304780
Answer:
11.11% (nearest hundredth)
Step-by-step explanation:
<u>Simple interest formula</u>
A = P(1 + rt)
where:
- A = final amount
- P = principal
- r = interest rate (in decimal form)
- t = time (in years)
Given:
- A = $3500
- P = $2800
- t = 2 years 3 months = 2.25 years
Substitute given values into the formula and solve for r:
⇒ 3500 = 2800(1 + 2.25r)
⇒ 3500 = 2800 + 6300r
⇒ 700 = 6300r
⇒ r = 1/9
Convert the interest rate into a percentage:
⇒ r × 100% = 1/9 × 100% = 11.11% (nearest hundredth)
Answer: The ladder is 5.3 m long
Step by step solution
1. Draw out the scenario, ie a right triangle where the hypotenuse is the ladder, the wall is 4.5m and the angle the ladder and the ground makes 58 degree.
2. Soh, Cah, Toa
The wall is opposite, the ground is adjacent, and the ladder is hypotenuse
Sine (58) = 4.5/h
3. Solve for hypotenuse
h * sine (58) = 4.5
h = 4.5/sine (58)
h = ~ 5.3 m

The measure of XW from the given diagram is 9. Since ZY = XW, hence ZY is also 9
Find the diagram of the question attached
From the diagram, ZY = XW
- ZY + YX = ZX
- YX + XW = YW
Subtract both expressions;
ZY - XW = ZX - YW
Since ZY = XW
The equation becomes XW - XW = ZX - YW
ZX - YW = 0
Given the following parameters
ZX = 5x + 17
YW = 10 - 2x
5x + 17 = 10 - 2x
5x + 2x = 10 - 17
7x = -7
x = -1
Get the measure of ZY and XW
XW = YW - YX
XW = 10 - 2x - 3
XW = -2x + 7
XW = -2(-1) + 7
XW = 2 + 7
XW = 9
Hence the measure of XW from the given diagram is 9. Since ZY = XW, hence ZY is also 9
