Answer:
scale factor: 1.16
perimeters: 21.84 ft and 25.36 ft
Answer:
10c = 20
5c = 5
Step-by-step explanation:
Let x be the number of 10c coins; let y be the number of 5c coins. The total is $2.25, so the amount of 10c and 5c coins will add to that. Simita has 25 coins, so x and y, the number of coins, will have to add to 25. Hence, solve the simultaneous equation.
10x + 5y = 225 (1) - times by 0
x + y = 25 (2) - times by 5
10x + 5y = 225 (1)
5x + 5y = 125 (2)
Then, take equation 2 away from equation 1.
5x = 100
x = 20
Substitute x back into the original equation.
x + y = 25
20 + y = 25
y = 5
<span> 2(lh + lw + wh) = 96
lh + lw + wh = 48
l(h + w) + wh = 48
3(3 + 4) + 12
Length = 3
Width = 3
Height = 4

Step-by-step explanation:
let
(-7,-8) =(x1, y1)
and (-6,7)=(x2, y2)
by the formula
d=√(y2-y1) ²+(x2-x1) ²
=√(7+8)²+(-6+7)²
=√15²+1²
= √225+1
= √226
Answer: 20%
Step-by-step explanation:
First determine how many times 25 fits in 125. It’s 5 right. Now turn that into a percent. That leading to 20%
