45% as a fraction would just be 45/100 because a fraction is just adding a 100 to make a denominator. (Only in the case of changing a percent to a fraction) If you choose the simplify your answer then the fraction would be <span>9/20</span>.

Answer:
Therefore the length of EC is 6.67 ft.
Step-by-step explanation:
Given:
BC = 12 ft
AC = 6.75 ft
DE = 3ft
DE is parallel to AC.
Angle C is 60°.
Angle A and Angle BDE are both right angles.
Triangle ABC is similar to Triangle DBE.
To Find:
EC = ?
Solution:
Δ ABC ~ Δ DBE ..................Given
If two triangles are similar then their sides are in proportion.
On substituting the given values we get
Now as B - E - C,
..........Addition property
substituting the given values we get
Therefore the length of EC is 6.67 ft.
8 nickels, because 8 (nickels) × 5 (worth) = 40
24 dimes, because 8 × 3 = 24 24 × 10 = 240
240 + 40 = 280
Answer:
2 ½ miles
Explanation:
mph = miles per hour, which means that if robert had run for the full 1 hour, he would have run 3 ⅓ miles.
however, since he only ran for ¾ of an hour, which is equal to 0.75, we can multiply the 3 ⅓ miles by 0.75 to get 2.5 or 2 ½ miles.
i hope this helps! :D
An isosceles triangle is one in which 2 angles have similar
measure while the other one is different. In this case, the 2 vertex angles
have a measure of 42 degrees, therefore the third angle which is equal to (2x +
3) is:
(2x + 3) + 42 + 42 = 180
2x + 3 = 96
<span>x = 46.5°</span>
