Answer:
3,36 in^2
Step-by-step explanation:
The geometric shape shown in image is called a trapezoid
to calculate the area of a trapezoid we use the following formula:
1/2*(a+b)*h (a and b are bases, h: height)
bases are 1.3 and 3.5 and height is 1.4
1/2(1.3 + 3.5)*(1.4) = 3,36 the area is stated in square units so the answer is
3,36 in^2
The answer of 799/4 is equal 1
Answer:
X/12
Step-by-step explanation:
X - whole drywall
X/4 -quarters
X/4/3=X/12 fraction of a whole sheet is each of these small pieces
Answer:
37 children
Step-by-step explanation:
to find how many students there were you are going to divide 888 by 24 so there are 37 children. that is one way another way is to draw it as a fraction so have it like this 888/24
Answer:
18.55
Step-by-step explanation:
Step One
Find AC
<em><u>Formula</u></em>
a^2 + b^2 = c^2
<em><u>Givens</u></em>
<em><u>Solution</u></em>
- AC^2 = 70^2 + 50^2 Substitute into Pythagoras
- AC^2 = 4900 + 2500 Expand
- AC^2 = 7400 combine
- AC = sqrt(7400) Take the square root of both sides.
- AC = 86.02
Step Two
Find FC
<em><u>Givens</u></em>
- <BCF = 30o Given
- BC = 50 Given
- FC = Find
<em><u>Formula</u></em>
Tan(30) = FC/50
<em><u>Solution</u></em>
FC = 50 * tan(30)
FC = 28.87
Step Three
Find <FAC
FC = 28.87
AC = 86.02
Tan(<FAC) = FC / AC
Tan(<FAC) = 28.87/86.02
Tan(<FAC) = 0.33558
<FAC = Tan-1(0.33558)
<FAC = 18.55 which is just about what you got.
