To solve this you would use the pythagorean theorem since the brace is making the frame look like two right triangles. The theorem states that for a triangle with a right angle, A^2+B^2=C^2. A and B are the sides of the frame and C is the brace which is like the hypotenuse of the triangle. It doesn't matter which side is A or B so you can put 6 or 8 in place of either in the equation. 6^2+8^2=C^2. If you simplify this it equals 36+64=C^2, which then simplifies to 100=C^2. Then you take the square root of both sides (what number multiplied by itself = the number you are trying to get, in this case, 100). So then you get C=10 because 10x10=100. So the length of the diagonal brace is 10ft.
Answer:
14 miles per hour
Step-by-step explanation:
The average speed would be the total distance divided by the total time = 35 miles divided by 2.5 hours is 14 miles per hour
Answer:
20
Step-by-step explanation:
area=width×height
=4×5 (because of how many squares there are)
=20
or you could count all the squares but timesing is eaier
Answer: W=20 and L=55
Step-by-step explanation:
2(3w-5)+2(w)=150
6w-10+2w=150
8w-10=150
8w=160
W=20
L= 3(20)-5
=60-5
=55
Step-by-step explanation:
9^8/9^2 ➡ 9^8-2 = 9^6 to divide this expression we subtract the bottom number from the top number
5^2 × 5^3 ➡ 5^2×3 = 5^6 to multiply this expression we multiply the powers
