Answer:
1.___ b
2.___c
3.___a
4.___d
Step-by-step explanation:
5% of x is =8
5/100 * X= 8
x=8*100/5=800/5=160
12% of x =5
x=41.666 approximately
8% of x=12
x=12*100/8=1200/8=150
5% of x= 12
x=12*100/5=1200/5=240
Answer:
Reduce the expression, if possible, by cancelling the common factors.[(2/3)^2]^3 X (2/3)^2 ÷ (2/3)^8 = 1
Step-by-step explanation:
4/9^3 x (2/3)^2 ÷ (2/3)^8
4/9^3 x 4/9 ÷ (2/3)^8
4/9^3 x 4/9 divided by 256/6561
64/729 x 4/9 divided by 256/6561
= 1
Answer:
15.6 hrs
Step-by-step explanation:
Walker A:
1.25 miles in 2.25 hrs
6/1.25 = 4.8
4.8×2.25 = 10.8
6 miles in 10.8 hrs
Walker B:
2.5 miles in 2 hrs
6/2.5 = 2.4
2.4×2 = 4.8
6 miles in 4.8 hrs
10.8 + 4.8 = 15.6
Answer:
x = sqrt(32)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+ b^2 = c^2
7^2 + x^2 = 9^2
49+x^2 = 81
Subtract 49 from each side
x^2 = 81-49
x^2 =32
Take the square root of each side
sqrt(x^2) = sqrt(32)
x = sqrt(32)
Quadrilateral LMNO is a rhombus ( the diagonals bisect each other ).
The system:
y = 3 x
y + 12 = 6 x
3 x + 12 = 6 x
6 x - 3 x = 12
3 x = 12
x = 12 : 4
x = 4
y = 3 * 4
y = 12
Answer: C ) 12
