Answer:
8
Step-by-step explanation:
use trig functions
2 sides and 1 angle given
Sides given
- hypotenuse -> x
- opposite side to 30˚ -> 4
Angle
trig function associated with hyp and opp is sin
sin(x) = opp/hyp
substitute
sin 30˚ = 4/x
solve for x
0.5 = 4/x
0.5x = 4
x = 8
Answer:
g
Step-by-step explanation:
I believe the correct given problem is:
“What is 80% in its simplest form as a fraction?”
Take note that you missed to place the percent sign which
is very important.
Now to solve this, 80% when converted to decimal form is
0.80 which means that you have 80 parts per 100 parts. Therefore the fraction
form of this would be 80 / 100.
fraction = 80 / 100
However this fraction is not yet the answer because we
can still simplify this further. First step in simplifying is to divide both
the numerator and denominator by 10 so that we are left with:
8 / 10
Next step is to divide by 2:
4 / 5
Now we can see that we can no longer divide this (numbers
should be whole number). Therefore the simplest form as a fraction is 4/5
Answer:
4/5
Step-by-step explanation:
So, x=width and the width=13+L. The formula for perimeter is 2(L)+2(W) and the total perimeter in this question is 62 feet. That means 2(L)+2(13+L)=62 feet. Solve for L and that's going to be your length. Add the length plus 13 and you'll have the width. Double check the equation by plugging the width and length back into the equation. (Does that help?)
Answer:
28j + 21
Step-by-step explanation:
combine like terms
7(2j+ 3+ 2j)
7(4j+3)
Distribute
7(4j + 3)
=
28j + 21
