A 32-foot ladder leans against a building. The distance between the bottom of the ladder and the base of the building is
8.5 feet. What is the height, in feet, from the ground to the place on the building that the ladder touches? Round your
answer to the nearest tenth.
Answer:14
Step-by-step explanation:
happy 5685757
The height at which the ladder touches the building is required.
The height of building where the ladder touches the building is 30.9 feet.
Pythagoras theorema = Required height
b = Distance between the bottom of the ladder and the base of the building = 8.5 feet
c = Length of ladder = 32 feet
From the Pythagoras theorem we have
[tex]a^2+b^2=c^2\\\Rightarrow a=\sqrt{c^2-b^2}\\\Rightarrow a=\sqrt{32^2-8.5^2}\\\Rightarrow a=30.9\ \text{feet}[/tex]

Pix diameter = Circumference
A group of students stood in a circle to play a game. The circle had a diameter of 22 meters.
Which measurement is closest to the circumference of the circle in meters?
A 34.54 m
B 1,519.76 m
C 379.94 m
D 69.08 m
Answer:
69.08m
Step-by-step explanation:
Circumference of a circle = πd where
d is the diameter of the circle
Given
diameter = 22metres
circumference of the circle = 3.14(22)
circumference of the circle = 69.08m
Hence the circumference of the circle is 69.08m

Simplify the expression to one number using order of operations:
\frac{-8\left(2-6\right)}{2}
2
−8(2−6)
First, let's solve the subtraction (in parentheses):
[tex]\mathsf{\dfrac{-8\left(2-6\right)}{2}}[/tex]
[tex]\mathsf{\dfrac{-8(-4)}{2}}[/tex]
Now, let's solve the multiplication. Remember: in multiplication, two negative numbers will give a positive number:
[tex]\mathsf{\dfrac{-8(-4)}{2}}[/tex]
[tex]\mathsf{\dfrac{32}{2}}[/tex]
Finally, let's solve the division:
[tex]\mathsf{\dfrac{32}{2} = 16}[/tex]
Answer: 16This week, the art museum gave away 1,200 tickets to the Greco exhibit, which was 150 percent as many tickets as it gave away last week. Martin is trying to figure out how many tickets the museum gave away last week. His work is shown below.
Step 1: StartFraction part Over whole EndFraction = StartFraction 150 Over 100 EndFraction = StartFraction question mark Over 1200 EndFraction
Step 2: 100 times 12 = 1200
Step 3: 150 times 12 = 1800
In what step did Martin make a mistake, if any?
Step 1: Martin should have written his ratio as StartFraction 1200 Over question mark EndFraction.
Step 2: Martin should have divided 1200 by 8.
Step 3: Martin should have added 1200 and 150.
Martin did not make any mistakes.

Phyllis invested $13,000, a portion earning a simple interest rate of 5¼% per year and the rest earning a rate of 5% per year. After one year the total interest earned on these investments was $672.50. How much money did she invest at each rate?
Answer:
Phyllis invested $9000 at the rate of 5.25% and $4000 at the rate of 5%.
Step-by-step explanation:
Formula for the simple interest is,
Interest = [tex]\frac{P\times r\times t}{100}[/tex]
Here, P = Principal amount
r = rate of interest
t = Duration of investment
Let Phyllis invested amount (at 5.25% rate of interest) = $x
Therefore, Interest on this amount,
Interest = [tex]\frac{5.25\times x}{100}[/tex]
= $0.0525x
If he invested the rest amount $(13000 - x) at the rate of 5%,
Interest earned on this amount = [tex]\frac{(13000-x)\times 5\times 1}{100}[/tex]
= $(650 - 0.05x)
Interest earned on total amount = $672
Therefore, $0.0525x + $(650 - 0.05x) = $672.5
0.0025x + 650 = 672.5
0.0025x = 22.5
x = $9000
Rest amount = 13000 - 9000
= $4000
Phyllis invested $9000 at the rate of 5.25% and $4000 at the rate of 5%.

Hey there!
2(x + 10)
REMEMBER A VARIABLE BY ITSELF IS UNDERSTOOD AS AN INVISIBLE 1
= 2(1x + 10)
DISTRIBUTE “2” WITHIN PARENTHESES
= 2(1x) + 2(10)
= 2x + 20
Therefore, your answer should be: 2x + 20
Good luck on your assignment and enjoy your day!
