Answer:
35
Step-by-step explanation:
Make equations, l = w+5 and 2l + 2w = 150
Substitute w+5 into 2l + 2w = 150
Simplify to get 4w + 10 = 150
Subtract 10 from both sides to get 4w = 140
Divide both sides by 4 and you get 35 as width
Answer:
Radius = 8.575 cm
Step-by-step explanation:
Formula for volume of a pyramid is;
V_p = ½Ah
Where A is area of base and h is height
Also, formula for volume of cone is given as;
V_c = ⅓πr²h
Now, we are told that V_p = V_c and that h is the same for both shapes.
Thus ;
½Ah = ⅓πr²h
h will cancel out to give;
½A = ⅓πr²
Cross multiply to give;
3A/2π = r²
Base area of pyramid is given as 154 cm². Thus;
(3 × 154)/2π = r²
r = √((3 × 154)/2π
r = 8.575 cm
100+30=130
100+40=140
online price is 130% or original
superstore price is 140% or original
the difference bewteen them is 140-130=10% of the original price
A. 1.3 times 160=208=online
1.4 times 160=224=superstore
B. difference is 224-208=16=10% of 160
it is 10% of the original price
A. online=$208
superstore=$224
B. $16, this is 10% of the original price
Three consecutive odd integers: n, n + 2, and n + 4
n + (n + 2) + (n + 4) = 165
3n + 6 = 165
3n + 6 - 6 = 165 - 6
3n = 159
3n / 3 = 159 / 3
n = 53
So the first number is n, or 53.
The second number is n + 2, or 55.
The third number is n + 4, or 57.
