Answers
Answer:
B
Step-by-step explanation:
You would use the formula Length×Width×Height
In this question the length would be 67 in
The height would be 9 in
And the width would be 50 in
The unit of measure is inches
Cubed because this is a 3-dimesional shape
So the answer would be (50×67×9) in³

The equation represents 21 seats and 30 wheels will be given as B.
u + 2b = 30
What is an equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
The owner of a bike shop sells unicycles and bicycles and keeps inventory by counting seats and wheels. One day, she counts 21 seats and 30 wheels.
u is the number of unicycles and b is the number of bicycles.
There are total 21 seats
⇒ u+b=21
unicycle has 1 wheel and bicycle has 2 and total there are 30 wheels
⇒ u+2b=30
Hence,the equation represents 21 seats and 30 wheels will be given as B. u + 2b = 30

Julianna has thirty two pieces of candy in a candy jar. Julianna only has two kinds of candy,
jolly rangers and twix. For every four twix bars, she has two pieces of jolly rangers. How many
pieces of each candy are in the candy jar?
Answers
a. The number of twix bars is 21
b. The number of jolly rangers is 11.
Julianna has thirty two pieces of candy and has four twix bars for every two jolly rangers, we need to find the ratio of candy bars.
What is the ratio of candy bars?Let
x = number of twix bars and y = number of jolly rangers.Since for every four twix bars, she has two pieces of jolly rangers, the ratio of candy bars is
x:y = 4:2 = 2:1
a. Number of twix barsThe number of twix bars is 21
The number of twix bars x = ratio of twix bars/total ratio × total number of candy bars
So, x = 2/(1 + 2) × 32
= 2/3 × 32
= 64/3
= 21.33
≅ 21
So, the number of twix bars is 21
b. Number of jolly rangersThe number of jolly rangers is 11.
The number of jolly rangers y = ratio of jolly rangers/total ratio × total number of candy bars
So, y = 1/(1 + 2) × 32
= 1/3 × 32
= 32/3
= 10.66
≅ 11
So, the number of jolly rangers is 11.

[tex]\implies \sf-\dfrac{4ac}{4a^2}+\dfrac{b^2}{4a^2}=\dfrac{-4ac+b^2}{4a^2}[/tex]
Finally, change the order of the terms in the numerator so that [tex]\sf b^2[/tex] is first:
