1. 10
2. 5√2 in
1. The ratio for a 30-60-90 triangle is x:x√3:2x
x is the shortest leg so 2*x =2*5 = 10
2. the ratio of a 45-45-90 triangle is x:x:x√2
x is one leg so x * √2 = 5*√2 = 5√2
Well, all we have to do to figure out if Ms. Lee’s offer is reasonable is multiply the unit price ($18) by 7
18 x 7 = 126
Since she offered $146, she could actually purchase 8 pennants for $144
Therefore, her answer wouldn’t be reasonable
Hope this helps you

The answer is A -0.7
-2(n) + 1.8 simplifies to:
-2n + 1.8 = 3.2
- 1.8 -1.8
-2n = 1.4
n = -7
Answer:
5 of the 7 boxes are 8 inches in height
Step-by-step explanation:
Mathematically;
1 ft = 12 inches
So, 5 ft will measure 5 * 12 = 60 inches
So from what we have ,
We want to combine 8 and 10 inches to give 60 inches total
Let the number of 10 inches be x and the number of 8 inches be y
Mathematically;
x + y = 7 •••••(i)
10x + 8y = 60 ••••(ii)
From equation i, x = 7-y
Put this in equation ii
10(7-y) + 8y = 60
70-10y + 8y = 60
70-60 = 10y-8y
2y = 10
y = 10/2
y = 5
