Which of the ratios below has a unit rate of 40? Select all that apply.
A) 60:20
B) 5:180
C) 120:3
D) 480:12
E) 80:2
Answer:
C, D, E
Step-by-step explanation:
To find the unit rate, divide the first value by the second one
After doing this, only answer choices C, D, and E have a unit rate of 40.
120/3 = 40
480/12 = 40
80/2 = 40
So, the answer is C, D, and E
A hummingbird flaps its wings 8,400 times in 120 seconds. how many times can it flap its wings in 35 seconds?
Answer:
2450 times per minute (if my math is correct)
Step-by-step explanation:
A hummingbird should flap it's wings 2100 times in 30 seconds and 350 times in 5 seconds if you use a table. 2100+350=2450
Answer:
Step-by-step explanation: 8,400 divided by 35.

Evaluate the following expression for m=9
Answer:
That is 4
Step-by-step explanation: First you need to substitute 9 in for m. Then multiply 4 x 9 to get 36. Then the square root of 36 is 6. Lastly 6-2 equals 4.

If a«b a = 18 when b = 3, then find a when b = 5
I need help asap
Answer:
a = 30
Step-by-step explanation:
Given the following data;
a = 18
b = 3
This is a direct proportion question.
Therefore, a is directly proportional to b.
Mathematically, a = kb
First of all we would find the constant, k;
k = a/b
k = 18/3
k = 6
Now to find the value of a when b = 5
a = kb
a = 6*5
a = 30

Rafael and Roger played tennis against each other 30 times. Each of the times they played, either Rafael won or Roger won.
The ratio of the number of times Rafael won to the number of times Roger won is 7:3
(a) Work out the number of times Rafael won.
Answer:
Rafael won 21 times.
Step-by-step explanation:
Add 7 + 3 together = 10
30 divided by 10 = 3
3 x 7 = 21

16% of the town's population are above the age of 65. If there are 320 residents are over the age of 65, approximately what is the town's total population?
Answer:
the total population is 2,000
Step-by-step explanation:
so if we double 16 we get 32% and we have 640 residents then we ad 8% which gets us to an even number of 40% and therefor we add half the 16% to our 640 to get 800 and this is sounding complicated but stick with me. now that we have 40% of the population is 800 people then 80% is 1,600 then we add half or 20% and get 100% is 2,000 people

Question 2 (5 points)
Find the greatest common factor of 48xy3z, 24x2y3z, and 56x2yz.
A) 16xyz
B) 8xyz
C) 8xyz
D) XyZ
Answer:
The greatest common factor is 8xyz
Step-by-step explanation:
To find the greatest common factor of an expression involving numbers and variables, we find each greatest common factor separately.
Numbers:
48, 24 and 56.
We find the greatest common factor factoring them simultaneously while all can be factored by the same number. The GCF is the multiplication of the factors. So
48 - 24 - 56|2
24 - 12 - 28|2
12 - 6 - 14|2
6 - 3 - 7|
They cant be factored by the same factors anymore, so the numeric GCF is 8.
Variables:
For each variable, the GCF will be the lowest exponent.
Variable x: We have exponents 1, 2 and 2. So the GCF is [tex]x^1 = x[/tex]
Variable y: We have exponents 3, 3 and 1. So the GCF is [tex]y^1 = y[/tex]
Variable z: We have exponents 1, 1 and 1. So the GCF is [tex]z^1 = z[/tex]
The greatest common factor is:
[tex]8*x*y*z = 8xyz[/tex]
Answer:
8xyz
Step-by-step explanation:

In a crate of 30 eggs, 6 were broken. What percentage of eggs are
Score
(i) broken? (ii) not broken?
Step-by-step explanation:
(i) broken eggs
(6÷30) * 100% = 20%
(ii) not broken
solution 1: 100%-20% = 80%
solution 2:
[tex] \frac{30 - 6}{30} \times 100\% = 80\%[/tex]
