<span>1/5
This is a matter of elimination. So let's figure out how many of each display there is.
30% of 150 = 0.30 * 150 = 45 displays about electricity.
2/5 * 150 = 0.40 * 150 = 60 displays about renewable energy
1/10 * 150 = 150/10 = 15 displays about gas.
The rest of the displays are about nuclear power. So
150 - 45 - 60 - 15 = 30 displays about nuclear power. Since we want a fraction, we get 30/150
But 30/150 isn't in it's simplest form. The largest number that will evenly divide both 30 and 150 is 30. So divide both the numerator and denominator by 30
(30/30)/(150/30) = 1/5
So 1/5 of the displays are about nuclear power.</span>
Answer:
b = 125
Step-by-step explanation:
Given a varies directly as
then the equation relating them is
a = k
← k is the constant of variation
To find k use the condition a = 3 , b = 64 , then
3 = k
= 4k ( divide both sides by 4 )
= k
a =
← equation of variation
When a =
, then
=
( multiply both sides by 4 to clear the fractions )
15 = 3
( divide both sides by 3 )
5 =
, then
b = 5³ = 125
Well, since the area is 504. ANd the width is 14.
You do 504 divided by 14. Which is 36.
The poster is 36 centimeters.
The equation is 504/14=x
x=36

Answer:
x = 5
y = 46
z = 88
Step-by-step explanation:
x is opposite one of the equal base angles. The other side is marked 5. Therefore x = 5
y is opposite one of the equal sides. It is an angle. It is equal to the other base angle whose measurement is given. y = 46
y + 46 + z = 180 All triangles have 180 degrees. y = 46 (above)
46 + 46 + z = 180
92 + z = 180 Subtract 92
z = 180 - 92
z = 88
