Answer:
A = 48 ft²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = bh ( b is the base and h the perpendicular height )
here b = 16 and h = 6 , then
A = × 16 × 6 = 8 × 6 = 48 ft²
B:942$
(pi*20^2)/2 is approximately 628.32
628.32*1.5=942.48
it looks like its all right to me
If it's not too late by now, the answer is 19.9
$1.90
Represent the numbers of nickels, dimes and quarters by n, d and q.
Then: d + q = 9, or q = 9 - d.
Also, n + d = 10
Lastly, n + d + q = 15.
Let's substitute 9 - d for q in the equation immediately above:
n + d + (9 - d) = 15, or n + 9 = 15. Then n must be 6.
In summary, Jim has 6 nickels, (10 - 6) dimes and (9 - 4) quarters, or:
6 nickels, 4 dimes and 5 quarters
Thus, he has 5($0.05) + 4($0.10) + 5($0.25), or
$0.25 + $0.40 + $1.25, or $1.90
I'm pretty sure you are only meant to draw a rectangle of 34 I'm not sure tho.
