Find EF in the trapezoid. How can I solve for this?

Mathematics
1 answer:
devlian [24]3 years ago
6 0

Answer:

Ef=52

Step-by-step explanation:

By the mids segment theorem if a line sgement has endpoints on the midpoints of 2 sides of a triangle then it is half the size of the third side.

That means

2(4x+8)=9x-5

8x+16=9x+5

11=x

Then plug it back in to EF

4(11)+8

44+8

52

11 is 40% of whst number
SOVA2 [1]
11 is 40% of 27.5

Change the percentage to a decimal by dividing it over 100:
\frac{40}{100} = 0.4

Divide 11 over 0.4:
\frac{11}{0.4} = 27.5

The price that a company charged for a computer accessory is given by the equation 100-x^2 where x is the number of accessories
Setler79 [48]

Answer:

1.45 million accessories

Step-by-step explanation:

we need to write an algebraic equation

y = (100 - 10x^2)x - 10x

y represents the profit

x represents the # of accesories produced in millions

I used 10 because that's the cost of making each accessory

100-x^2=consumer price

x-10x= accessory-cost to make all the accessories

we know that 2 million accessories make 100 million

so the number of accessories that approximately make 100 should be around 2 million

in the options 1.45 is given which is close to 2

even though 3.45 is closer than two you would go beyond a 100 million profit which isn't what you want

if the options weren't given you would have to use all values from 1-2 as "x"

hope this helps!

The length of a rectangle is 5yd longer than its width. If the perimeter of the rectangle is 54yd , find its length and width.
Sladkaya [172]

Answer:

L = w + 5

P = 2(L+w) = 42

L + w = 21

w+5 + w = 21

2w + 5 = 21

2w = 16

w = 8 ft

L = w+5 = 13 ft.

Rectangle is 13 ft by 8 ft

Area = 13(8) = 104 ft2

Check: P = 2(L+w) = 2(13+8) = 2(21) = 42 ft
