Answer:
2. 39 cm
Step-by-step explanation:
Jack is 1.79m
1.79 + 2.8= 4.59 m
4.59-4.2= 0.39m
0.39 m= 39 cm
Answer:
area ≈ 6.3 units²
Step-by-step explanation:
Calculate the area (A ) of the sector as
A = area of circle × fraction of circle
= πr² × 
= π × 4² × 
= 16π × ← cancel 8 and 16 by 8, leaving
A = 2π ≈ 6.3 units² ( to 1 dec. place )
Answer:
1
Step-by-step explanation:
The product of 8 and a number ...with y being the number
34x+95=3(14x+9)
We move all terms to the left:
34x+95-(3(14x+9))=0
We calculate terms in parentheses: -(3(14x+9)), so:
3(14x+9)
We multiply parentheses
42x+27
Back to the equation:
-(42x+27)
We get rid of parentheses
34x-42x-27+95=0
We add all the numbers together, and all the variables
-8x+68=0
We move all terms containing x to the left, all other terms to the right
-8x=-68
x=-68/-8
x=8+1/2
