The top of a ladder is placed against the side of a house. The ladder is 15ft long and the wall is 12ft high. How far from the wall will the base of the ladder be positioned if the top of the ladder meets the top of the wall.
Answer:
9ft
Step-by-step explanation:
The top of a ladder is placed against the side of a house. The ladder is 15ft long and the wall is 12ft high. How far from the wall will the base of the ladder be positioned if the top of the ladder meets the top of the wall.
We solve this question using Pythagoras Theorem
c² = a² + b²
Height of the wall = Opposite side = b = 12ft
Length of the ladder = Hypotenuse = c = 15ft
Distance between the wall and the base of the Ladder = Adjacent = a
Hence:
15² = a² + 12²
a² = 15² - 12²
a = √15² - 12²
a = √81
a = 9 ft
Therefore, the wall will be 9ft from the base of the ladder , if the top of the ladder meets the top of the wall

What is Right Angled Triangle?Right angled triangle are those triangle for which one of the angle is 90 degrees.
Given a right angled triangle ABC.
Given that angle C is right angle.
Side AB is the hypotenuse, AC is the base and BC is the altitude.
Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.
Using the theorem,
(AB)² = (AC)² + (BC)²
(BC)² = (AB)² - (AC)²
= 17² - 8²
= 289 - 64
= 225
BC = √225 = 15 units
Hence the side length of BC is 15 units.

Brian has saved five dollars in dimes quarters and half dollars she finds that she has 30 coins all together and there are four times as many quarters as there are half dollars how many dimes does Brian have
9514 1404 393
Answer:
20 dimes8 quarters2 half-dollarsStep-by-step explanation:
Let d, q, h represent the numbers of dimes, quarters, and halves Brian has. We can write 3 equations in these 3 variables:
10d +25q +50h = 500 . . . . value of the coins, in cents
d + q + h = 30 . . . . . . . . . . . total number of coins
4h = q . . . . . . . . . . . . . . . . . four times as many quarters as halves
Using the last equation to substitute into the other two, we get ...
10d + 150h = 500
d +5h = 30
The second equation can be written as ...
5h = 30 -d
and the first can be written to facilitate substitution:
10d +30(5h) = 500
10d +30(30-d) = 500 . . . . . substitute for 5h
900 -20d = 500 . . . . . . . . . simplify
400 = 20d . . . . . . . . . . . . . add 20d-500 to both sides
d = 20 . . . . . . . . . . . . . . . . divide by 20

What is the percent of change from 500,000 to 800,000?
The values will vary by a percentage of 60%.
What is percentage change?
Finding the difference between two values in a time series, dividing that difference by the initial value, and multiplying by 100 are used to determine the percentage change between the two values.
Given two values 500,000 and 800,000
From the general formula of percentage change
percentage change = (final value - initial value)/ initial value * 100
Percentage change = (800,000 - 500,000)/500,000* 100
Percentage change = 60
Therefore, the percentage change of the given values will be 60%.

Melissa has her own catering service. So far this year her company has generated income of $45,750. If she charges an average of $350 for each catering job, which linear equation could be used to find the company's total (t) income after completeing jobs?
Answer:
t = 350x + 45,750
Step-by-step explanation:
The linear equation that would represent this scenario perfectly would be the following
t = 350x + 45,750
In this equation, the variable x represents the total number of catering jobs that Melissa and her company are completing. This variable gets multiplied by the cost that she charges for each individual job. Finally, the total amount of money that she has already made so far this year is added to that product to give us the total income that she would make for the year after completing the jobs.
