Answer:
See below
Step-by-step explanation:
It is NOT a RIGHT triangle so you <u>cannot use</u> 1/2 b * h
but you can use Heron's Formula
Area = sqrt( s (s-a)(s-b)(s-c) )
s = semi- perimeter = (3+6+7)/2 = 8
Area = sqrt ( 8 ( 8-3)(8-6)(8-7) ) = sqrt ( 80) = 8.9 cm^2
A. d=45t
b. 112.5 miles. 112.5=45•2.5
The line is 4 units in length.
Answer:
The number is -9.
Step-by-step explanation:
If we let the number be x we have the equation 6x + 7 = -47.
6x + 7 - 7 = -47 - 7
6x = -54
x = 054/6
x = -9.
Answer:
5/6 cups of sugar
Step-by-step explanation:
45 divided by 18 = 2.5
1/3 x 2.5 = 0.83
0.83 = 5/6 cups
