Answer:
2n +14 = 30 I can use inverse operations and solve for n.
Step-by-step explanation:
twice means 2 so twice a number,n, means 2 times n thus 2n.
sum means add so, 2n + 14
is means equal so 2n + 14 = 30
If you solve it you will find n = 8
10*6=60marbles

Answer:
a) area will be 1/4 of the original
b) 7 cm²
Step-by-step explanation:
<h3>a)</h3>
Consider the equation for the area of a trapezoid:
A = 1/2(b1 +b2)h
Now, halve each of the dimensions:
A' = 1/2((1/2)b1 +(1/2)b2)((1/2)h)
A' = (1/4)(1/2(b1 +b2)h) = 1/4A
The area is multiplied by the square of the scale factor: (1/2)² = 1/4.
__
<h3>b)</h3>
The area of the smaller trapezoid will be ...
A' = 1/4A = (1/4)(28 cm²) = 7 cm²
Answer:
52%
There were 50 Students surveyed
12 girls preferred to work at the senior center
14 boys preferred to work at the senior center
12 + 14 = 26 students prefer to work at the senior center
26 students out of 50 students= 26/50
26/50= 52%
