squares q,r,t form a right triangle with dimensions as shown in the diagram. what is the area of square Q
Answers
Answer:
The area of square Q is 441 m² ⇒ C
Step-by-step explanation:
Let us use the right triangle to find the side of square Q
∵ The length of the side of square T = 29 m
∴ The length of the hypotenuse of the right triangle = 29 m
∵ The length of the side of square R = 20 m
∴ The length of leg1 of the right triangle = 20 m
∵ (leg1)² + (leg2)² = (hypotenuse)² ⇒ Pyathagoras Theorm
∴ (20)² + (leg2)² = (29)²
∴ 400 + (leg2)² = 841
→ Subtract 400 from both sides
∴ (leg2)² = 441
→ Take √ for both sides
∴ leg2 = 21
∵ Leg2 is the side of the square Q
∴ The length of the side of square Q = 21 m
∵ Area of the square = side × side
∴ Area of square Q = 21 × 21
∴ Area of square Q = 441 m²
∴ The area of square Q is 441 m²

Denise wants to cover a 21.75 square foot wall with weathered wood. If each box of weathered wood contains 1.5 square feet of wood, how many boxes of weathered wood does she need?
Answers
Answer: 15 boxes
Step-by-step explanation:
From the question, we are informed that Denise wants to cover a 21.75 square foot wall with weathered wood and that each box of weathered wood contains 1.5 square feet of wood.
The number of boxes of weathered wood that she need will be calculated by dividing 21.75 square feet by 1.5 square feet. This will be:
= 21.75/1.5
= 14.5
= 15 boxes approximately

z = 77
Step-by-step explanation:
Given
[tex]\frac{z}{7}[/tex] - 9 = 2 ( add 9 to both sides )
[tex]\frac{z}{7}[/tex] = 11 ( multiply both sides by 7 to clear the fraction )
z = 77
z/7=2+9
then simplify.
z/7=11
The last step is to multiply both sides by 7.

Your friend says the solution to 6x + 19x - 3 = 5(5x + 6) is x = 33. Solve 6x + 19x-3 = 5(5x + 6). What was your friend's likely error?
Answers
Answer: Forgot to divide at the end
Step-by-step explanation:
To figure out your friend's error, solve the equation yourself.
Distribute the 5 to get 25x+30Combine like terms in the first equation toget 25x-3=25x+30Add 3 to the other side.When we do this, we realize adding 3 would make it 33. This shows that the friend likely forgot to divide by 25 to completely isolate x, and stopped at that step.

Answer:
n5 + 17
Step-by-step explanation:
They're asking for a pattern.
17 + 5 = 22
22 + 5 = 27
27 + 5 = 32
So it starts at 17 and increases by five each time.
The nth term increases by 5 each time and starts at 17. That means the nth term is multiplied by 5 each time, but you have to add 17 because that's where the pattern starts.
