Simple, take 3 1/2 turn it into a decimal which = 3.50 since
1/2 = 0.5 because 1 divide by 2 = 0.5
Same thing for 1 1/4 = 1.25 since
1/4 = 0.25 because 1 divide by 4 = 0.25
3.50 divide by 1.25 = 2.8 miles one hour.
Answer:
This is NOT a one solution problem.
Step-by-step explanation:
Group all terms with a c in it to the left of the equal sign, and group all numbers to the right of the equal sign.
5.7c-1.5+3.2c=7.8c-1.5+1.1c
5.7c + 3.2c - 7.8c - 1.1c = - 1.5 + 1.5
8.9c - 8.9c = 0
0 = 0
No matter which number you substitute for c, it will always be true. Since you can find infinity of solutions, this is NOT a one solution problem.
Perimeter of the new triangle is 576 ft
Step-by-step explanation:
- Step 1: Given the perimeter of the right triangle = 72 ft. Find new perimeter.
Perimeter of the triangle = sum of the sides = a + b + c = 72
Each side is multiplied by 8, so new sides are 8a, 8b, 8c
⇒ New perimeter = 8a + 8b + 8c = 8(a + b + c) = 8 × 72 = 576 ft
The value is 11.
121^1/24 is actually square of 121^1/12
so x= square of 121 = 11
