Answer:

BC = 4.8
ED = 1.1
DF = 1.6

Step-by-step explanation:

Since angles A and E correspond, as well as angles C and F, we can say ...

ΔABC ~ ΔEDF

Then the ratio of side lengths of ΔABC to those of ΔEDF is ...

AC/EF = 6/2 = 3

That means ...

ED/AB = 1/3

ED = AB·(1/3) = 3.3·(1/3) = 1.1

For the remaining sides, we have the relation

3·DF = BC

3·(BC -3.2) = BC

2BC - 9.6 = 0 . . . eliminate parentheses, subtract length BC

BC -4.8 = 0 . . . . . divide by 2

BC = 4.8 . . . . . . . . add 4.8

DF = BC·(1/3) = 1.6

The unknown side lengths are BC = 4.8, DE = 1.1, DF = 1.6.

An artist wants to make alabaster pyramids using a block of alabaster with a volume of 576 cubic inches. She plans to make each

marta [7]

Answer:

144 pyramids

Step-by-step explanation:

The volume of a pyramid = 1/3*base area * height

Given: Base area = 3 sq.inches

Height = 4 inches

Volume of each pyramid = 1/3*3*4

= 4 cube inches.

To find the number pyramids can the artist make from block of alabaster artist, we need to divide 576 by 4.

= 576/4

= 144

Therefore, the artist can make 144 pyramids.

Thank you.

elixir [45]

Answer:

$\frac{1}{5}$

Step-by-step explanation:

Assuming a total of ten students were asked, $\frac{2}{10}$ chose football and $\frac{8}{10}$ chose other sports. $\frac{2}{10}$ simplified is $\frac{1}{5}$ , so that's the experimental chance that the next student favors football.

Which of these is an example of a literal equation?

RSB [31]

<u>ANSWER</u>

$ax-by=k$ is an example of literal equation.

<u>EXPLANATION</u>

A literal equation is an equation in which letters or variables are used to represent real values.

A literal equation consists of at least two letters or variables.

The first option consists of two variables but it is not an equation. It is just an expression.

The second option is not a literal equation because it consists of only one variable. This is just a linear equation in one variable. But a literal equation should have at least two variables or letters.

As for the third option, it does not even contain a variable or letter.
