Answer:
14 yards
Step-by-step explanation:
the area of a triangle is 0.5×b×h
so
plug in what you have
0.5×b×3=21
(3x0.5)b=21
1.5b=21
b=21/1.5
b=14
An absolute value equation which could represent the length of a plane is : 12 feets ≥ x ≤ 302 feets
Smallest length of a plane = 12 feets
Longest length of a plane = 302 feets
This means that the minimum length of a plane cannot be below 12 feets and the maximum length of a plane cannot be above 302 feets
Using x as the length of a plane :
To represent as an absolute value ; we use inequality :
Minimum length ≥ x ≤ maximum length
12 feets ≥ x ≤ 302 feets .

Answer:
C
Step-by-step explanation:
Let dimes = d and quarters =q
D + q = 50
D= 50-q
0.10d + 0.25Q = 7.70
Replace d with 50-q:
0.10(50-q) + 0.25q = 7.70
Simplify:
5 -0.10q + 0.25q = 7.70
5 + 0.15q = 7.70
Subtract 5 from both sides:
0.15q = 2.70
Divide both sides by 0.15:
Q = 2.70 / 0.15
Q = 18
D = 50-18 = 32
There are 32 dimes and 18 quarters
