Answer:

x = 8

Step-by-step explanation:

do distribution: 4x - 28 + 12 = 16

simplify: 4x - 16 = 16

add 16 to both sides: 4x = 32

divide both sides by 4: x = 8

Let me know if you need me to explain it more, good luck!

27. A 35 foot long tube is cut into two pieces with ratio 4:5 Find the length of the shorter piece.
polet [3.4K]

Answer:

x= 16 ft.

Step-by-step explanation:

Let 'x' and 'y' are the lengths of the two pieces then:

1.) x + y = 36

2.) x : y = 4 : 5 cross multiply

3.) 5x = 4y

by solving the system of equations

x + y = 36

5x = 4y

we find

x = 16 ft

y = 20 ft

A random variable is a function that assigns numerical values to the outcomes of a random experiment. True or false?
Alex787 [66]

Answer:

FALSE

Step-by-step explanation:

A random variable is a variable whose outcome depends on random criteria, such as a lottery game in which any number can be drawn randomly. That way, a randomized experiment will have random results that are not predetermined. For example, if the lottery has 80 numbers, the random variable function can achieve any result, which will depend on random criteria such as the luck of the player.

Look at the picture for the problem
Serjik [45]

Answer:

w = 400

Step-by-step explanation:

2400 = lw

Divide the area by two.

2400 / 2 = 1200

Now this cannot be the answer since the length is longer than the width.

Divide 1200 by two again.

1200 = 600

Notice there are two choices that are the closest:

w = 800

w = 400

The latter choice would be the answer since again, the length is longer than width in terms of measurement
