Answer:

see explanation

Step-by-step explanation:

ΔABE and ΔACD are similar hence the ratios of corresponding sides are equal, that is

\frac{AB}{AC} = \frac{AE}{ED} = \frac{BE}{CD}

Using the first pair of ratios then

\frac{20}{5} = 4 = \frac{26}{ED}, hence

4ED = 26 ( divide both sides by 4 )

ED = 6.5 cm

------------------------------------------------------------------

(b)

Similarly

\frac{BE}{18} = 4, hence

BE = 4 × 18 = 72 cm

Is this correct please help!

Answer:

Almost...

The correct answer would be

To find the area of the base, multiply 15 times 16 then divide by 2

Then multiply by 19 to find the volume of the shape

Step-by-step explanation:

The base is a triangle

The area of a triangle = base length times height divided by 2

The triangle has a base length of 16 and a height of 15

So to find the area of the base we multiply 15 times 16 and divide that by 2

The volume of a prism is equal to the area of the base times the length of the prism

The length of the prism is 19 so we would then multiply by 19

If, in 7 years, Susan will be 2 times as old as she was 3 years ago, what is Susan’s present age? PLEAZE EXPLAIN HOW AND DO IT W
belka [17]
Let Susan's present age be x

Now, after 7 years ( her age will become 7 +x then) she'll be 2 as old she was 3 years ago.

Her age 3 years ago must be x-3

Now according to question,

twice Her age 3 years ago = her age after 7 years

now,

2(x-3) = 7+x
2x-6 = 7+x
2x-x =7+6
x = 13
x = 13



Therefore, her age presenr age is 13 years.
