Answer:
33.33
Step-by-step explanation:
We have, 90% × x = 30
or, 90 / 100 × x = 30
Multiplying both sides by 100 and dividing both sides by 90,
we have x = 30 × 100 / 90
x = 33.33
If you are using a calculator, simply enter 30×100÷90, which will give you the answer.

Together, Matthew and Daniel have 67 DVDs. Matthew’s collection has 3 times as many DVDs as Daniel’s collection. Which equation can be used to determine the number of DVDs in Daniel’s collection?
A. 3x - x = 67
B. x + x = 67
C. 3x + x = 67
D. 3x = 67
Answer:
C. 3x + x = 67
Step-by-step explanation:
Means Mathew has 3 units and Daniel has 1 unit.
There's 4 units in total.
4x = 67
3x + x = 67
3x is Mathew's DVDs
x is Daniel's DVDs
According to his GPS, it will take Lanny 1 hour to travel 40 miles. Which expression shows how to determine the speed in miles per hour?
40 miles ÷ 1 hour
1 hour ÷ 40 miles
1 mile ÷ 40 hours
40 hours ÷ 1 mile
Answer:
40 ÷ 1
Step-by-step explanation:
Speed = Distance : Time
Speed = 40 ÷ 1
You are renting a car that charges a $30 fee plus 40 cents a mile. The rate of change is $30.
True or False?
Hi there!
»»————- ★ ————-««
I believe your answer is:
False.
0.40 is the rate of change.
»»————- ★ ————-««
Here’s why:
As mentioned in the scenario, the car company charges a $30 fee which is flat. The '30' is the base for the total cost. The car company also charges 40 cents for every mile driven. This means that the company would charge a 40 cents for a mile driven. 40 cents would be the rate of change, not $30.⸻⸻⸻⸻
Side Note:
An equation that represents the situation could be:
[tex]C = 0.40m + 30[/tex]
'C' is the total cost for renting the car.
'm' is the number of miles the car is driven.
⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Leon is buying a bicycle. The regular price of the bicycle is x dollars. The bicycle is on sale for 20% off. He has to pay 5% sales tax on the sale price of the bicycle.
To represent his total cost, Leon writes the expression shown. 1.05(x – 0.2x). Which expression also represents Leon’s total cost?
Answer:
B. 0.84
Step-by-step explanation:
Hope this helps
total cost= 1.05(x-0.2x)
= 1.05 (0.8x) = 0.84x
Answer:
B
Step-by-step explanation:
1.05(x - 0.2x) = 1.05x - .21x
1.05x - .21x = .84x
Expand and combine like terms.
(4b^2+3)(4b^2-3)
Answer:
16b^4-9
Step-by-step explanation:
Factoring gives us 16b^4+12b^2-12^2-9. Simplifying gives us the answer which is 16b^4-9
Answer:
[tex]16b^4-9[/tex]
Step-by-step explanation:
When multiplying binomials, we can use a method called FOIL (First-Outside-Inside-Last).
For [tex](t_1+t_2)(t_3+t_4)[/tex], let:
[tex]t_1\implies \text{First Term},\\t_2\implies \text{Second Term},\\t_3\implies \text{Third Term},\\t_4\implies \text{Fourth Term}[/tex]
In the FOIL method, the steps go:
[tex]\text{\textbf{F}irst: Multiply the first and third terms (first term of each binomial)},\\\text{\textbf{O}utside: Multiply the first and fourth terms},\\\text{\textbf{I}nside: Multiply the second and third terms},\\\text{\textbf{L}ast: Multiply the second and fourth terms (last term of each binomial) }[/tex]
Given [tex](4b^2+3)(4b^2-3)[/tex], we have:
[tex]\text{First: }4b^2\cdot 4b^2,\\\text{Outside: }4b^2\cdot -3,\\\text{Inside: }3\cdot 4b^2,\\\text{Last: }3\cdot -3,\\\rightarrow 16b^4-12b^2+12b^2-9[/tex]
Combine like terms:
[tex]\boxed{16b^4-9}[/tex]
Find the missing dimensions
Answer:
short base: 6 yards
long base: 8 yards
Step-by-step explanation:
Our understanding of your figure is shown below.
The question says the "shortest side" and the "width" have the same dimension. If the "width" is a reference to "height 6 yards", then it seems the "shortest side" is 6 yards. Since the slant sides are longer than the height, the "shortest side" is also the "short base."
The short base is 6 yards.
__
The long base overhangs the short base by 1 yard on either end, so it is a total of 2 yards longer than the short base. It it 6+2 = 8 yards long.
The long base is 8 yards.
Hope this is correct, if not then feel free to let me know. I'm sorry in advance if it is incorrect.

If a Car can drive 35 miles on 7 gallons of gas, how many miles can it travel on 2 gallons of gas (assuming miles per gallon is proportional)? Give and explain your answer.
Answer:
10 miles
Step-by-step explanation:
35/7 is 5 so therefore if you do 5+5+5+5+5+5+5 is 35
so that means 2 gallons which is 10

Step-by-step explanation:
There are 8 lines from 1 to 2, so plotting 1 1/2 (or 1.5) is right in between. I'm not sure how to add the picture back into the explanation, but I will try my best to explain. You want to plot your point for 1 1/2 4 lines after the 1. For the 2 1/4, you want to plot your point on the second line from the 2. Let me know if it doesn't make sense!
Answer: See the attached image below
1 1/2 is located at the exact midpoint between 1 and 2.
2 1/4 is located 2 tickmarks to the right of 2.
===================================================
Explanation:
Think of 1/2 as 4/8
The number 1 1/2 is the same as 1 4/8
So we start at 1 and move 4 tickmarks to the right to get at the exact midpoint (note there are 8 tickmarked spaces between any two whole numbers).
This places us exactly at the midpoint between 1 and 2.
-----------------
To plot 2 1/4, we will effectively plot 2 2/8 since 1/4 = 2/8
We start at 2 and then move 2 tickmarks to the right to arrive at 2 2/8

Look at the two patterns below: Pattern A: Starts from 9 and follows the rule "add 8" Pattern B: Starts from 9 and follows the rule "add 2" Select the statement that is true. The terms in Pattern A are 4 times the corresponding terms in Pattern B The terms in Pattern B are one fourth the corresponding terms in Pattern A. The first five terms in Pattern A are 0, 9, 17, 26, 35. The first five terms in Pattern B are 9, 11, 13, 15, 17.
Answer:
It should be the last statement.
Step-by-step explanation:
For statements 1 and 2, the amount added on is 4 times the other / 1/4 the other. Statement 3 isn't true because Pattern A starts with 9.
