Answer:
(5r + 6)(5r² + 4)
Step-by-step explanation:
Given
25r³ + 30r² + 20r + 24 ( factor the first/second and third/fourth terms )
= 5r²(5r + 6) + 4(5r + 6) ← factor out (5r + 6) from each term
= (5r + 6)(5r² + 4)

Answer:
(m x 2)+10
Step-by-step explanation:
Answer:
2m+10
Step-by-step explanation:
First you write down 10. Then, you see that the “More than” is there and that indicates that the expression is flipped, but added to the next part of the word problem, which makes it +10. Next you see that it‘s twice Mabel’s height which is 2*m which is then 2m. Then you put the expressions together and get 2m+10. Hope this helps.
There is a bag with 6 marbles. Three marbles are blue, 2 are red and 1 is green. What is the probability that you will randomly select a red marble? A green marble? What is the likelihood of those probabilities? Mike answered: The probability of selecting a red marble is 2 and that is likely. The probability of selecting green is 1 and that is certain. If yes, explain in writing, using appropriate vocabulary, why you agree with him. If no, explain in writing what mistakes Mike has made and justify your reasoning. Be sure to give the correct answers in your justification. Is Mike correct?
(PLEASE HELP THANK YOU)
Answer:
Mike is not correct.
Step-by-step explanation:
The probability is an "out of" statement. meaning out of all 6 marbles if 2 are red how what is the probability of choosing a red marble the answer is 2 out of 6 or 1/3 or 0.3333333etc. For green the probability is 1 out of 6 or 1/6 or 0.16666666etc

A tax of 7% was added on to the cost of a meal. If the tax paid was $1.40, what was the cost of the meal?
Answer:
The cost of meal is: $20
Step-by-step explanation:
Given
Percentage of tax = 7%
Also given that the amount of tax is $1.40
Let x be the price of meal
Then the tax will be 7% of x
It can be written mathematically as:
[tex]1.40 = 7\%\ of\ x[/tex]
We will simply solve this equation to get the price of meal
So,
[tex]1.40 = 0.07*x\\x = \frac{1.40}{0.07}\\x = 20[/tex]
Hence,
The cost of meal is: $20

There are five 6-inch sticks and five 10-inch sticks. These sticks can be attached end-to-end to make longer sticks. For example, you can take two 6-inch sticks and one 10-inch stick to make a 22-inch stick (6 + 6 + 10 = 22).How many different lengths of stick can be made out of at least one of the sticks?

Answer:
All of them are correct except for the last one which is incorrect
Step-by-step explanation:
All you need to substitute the answers given for "r" and see if its less than or equal to 2
- 3.5 [tex]\leq[/tex] 2 Correct (negative numbers are always smaller than a positive number)
- 2 [tex]\leq[/tex] 2 Correct (negative numbers are always smaller than a positive number)
-1 [tex]\leq[/tex] 2 Correct ( negative numbers are always smaller than a positive number)
0 [tex]\leq[/tex] 2 Correct ( 0 has a value much more less than the value of 2)
2 [tex]\leq[/tex] 2 Correct (they both have the same value as "2")
4 [tex]\frac{1}{4}[/tex] [tex]\leq[/tex] 2 Incorrect ( 4 [tex]\frac{1}{4}[/tex] has a much more greater value than 2, therefore this is incorrect)

Trina is 53 3/ 4 inches tall. Jillian is 1 1/ 2 inches taller than Trina and Jane is 1 1 /5 inches taller than Jillian. How tall is Jane?
Answer: Jane is 56 9/20 inches tall
Step-by-step explanation:
Trina 's height = 53 3/4inches
Jiliam height = 1 1/ 2 inches taller than Trina which means
53 3/4inches + 1 1/ 2 inches
Add whole numbers to whole numbers and fractions to fractions
53+ 1 3/4 + 1/2
54 (3+ 2)/4 = 54 5/4 = 54+ 1 1/4 = 55 1/4 cm
Jane is 1 1 /5 inches taller than Jillian which means
55 1/4 cm +1 1 /5 inches
Add whole numbers to whole numbers and fractions to fractions
55 + 1 1/4 + 1/5
56 (5 + 4)/20 = 56 9/20

The diameter of a baseball is approximately 3 inches. What is its volume? Round your answer to the nearest whole number.
A. 9 in^3
B. 13 in^3
C. 113 in^3
D. 14 in^3
Answer:
D Volume = 4/3
If the diameter is 3 inches the radius will be 1.5.
If you plug that in you get
V = 4/3
V=14.137
Step-by-step explanation:
hope this helps have a good day :) ❤
Volume = 14 (rounded to the nearest whole number)
Volume = 4/3 pie r^3
If the diameter is 3 inches the radius will be 1.5.
If you plug that in you get
V = 4/3 pie 1.5^3
V=14.137
So the answer is D. 14 in^3.
What is a volumetric formula?
The basic formula for the area of a rectangle is length x width, but the basic formula for volume is length x width x height. No matter how you refer to the various measurements, the calculation does not change. For example, you can use "depth" instead of "height".

Segmenting each digit in the figure based on its place value :
3 = 100 thousand place = 3 * 100,000 = 300000
2 = ten thousand place = 2 * 10,000 = 20000
0 = thousand place = 0 * 1,000 = 0
7 = hundred place = 7 * 100 = 700
4 = tens place = 4 * 10 = 40
9 = unit place = 9 = 9
(300,000 + 20,000 + 0 + 700 + 40 + 9)
The cell phone price was originally $457. It is now being sold for $318. State the change to the nearest percent
I really need help
Answer:
