How many 1/12 make a quarter?
Answer:
3
Step-by-step explanation:
3/12 = .25
.25 = a quarter
plz mark brainliest ! :)
Answer:
3
Step-by-step explanation:
Let the number of 1/12 that make a quarter be x.
x * 1/12 = 1/4
Multiply both sides by 12.
x * 1/12 * 12 = 1/4 * 12
x = 3

m =
Answer:
3/5
Step-by-step explanation:
As we move (right) from the first point to the second, we see x (the run) increasing by 10 and y (the rise) by 6. Thus, the slope of the line shown in the diagram is
m = rise / run = 6/10 = 3/5
Lonnie plans to join the gym. He must pay a $35 membership fee. He will
then pay $5 each month. What is the slope?
Answer:
5
Step-by-step explanation:
The slope will be the constant amount that the cost increases by each month.
In this situation, 5 is the slope, because he has to pay $5 each month.
35 is not the slope, and is instead the y intercept. This is because this is the cost at 0 months, since it is the membership fee.
So, the correct answer is 5.

hence c. Patrick Mahomes is right.
Volunteers for a human performance study were randomly divided into two groups. The first group had their flexibility measured in the morning after a short meditation session while the second group had their flexibility measured in the afternoon with no previous meditation session. The flexibility scores of the two groups were compared. This experiment was not double-blind because:
a. some of the volunteers stretched before they went to the study location.
b. volunteers were allowed to keep their eyes open while having their flexibility measured.
c. volunteers were randomized into the two groups.
d. the volunteers knew whether they had meditated before having their flexibility measured.
Answer:
C
Have a wonderful day!
The experiment was not double-blind because volunteers were randomized into the two groups. The correct option is c.
What is a double-blind experiment?A type of clinical experiment where neither the research team nor the subjects are aware of the treatment or intervention they are receiving until the trial is complete. As a result, the study's findings are less likely to be skewed.
Because neither the participant nor the clinician is aware of who has received what treatment, double-blind studies are regarded as the most trustworthy sort of research. This is done in an effort to lessen bias and the placebo effect.
Both the researchers and the test subjects must be uninformed of who is receiving the treatment and who is receiving a placebo in a double-blind trial.
Therefore, the correct option is c. volunteers were randomized into the two groups.

Which of the following functions represent exponential growth?
Which of the following functions represent exponential decay?
9514 1404 393
Answer:
1. a, b, c - represent growth
2. b, c, d - represent decay
Step-by-step explanation:
If increasing x results in a larger value, the function represents growth. If it results in a smaller value, the function represents decay.
__
To answer these questions, you can look at the base and the exponent. When we say "exponent" here, we mean the coefficient of the exponent variable. There are four possibilities:
growth:
exponent positive, base > 1exponent negative, base < 1decay:
exponent positive, base < 1exponent negative, base > 1__
Growth questions:
1.77^x -- growth
1.5^(x/2) -- growth
0.5^(-x) -- growth (= 2^x)
e^(-t) -- decay (e ≈ 2.718)
Decay questions:
1.7^x -- growth
1.7^(-2x) -- decay
(1/3)^x -- decay (= 3^(-x))
2^(-x) -- decay
The price of an Item has been reduced by 70%. The original price was $90. What is the price of the item now?
Answer:
The price of the item is $27.

Answer:
x = 19
Step-by-step explanation:
Since, both the triangles (small and large) given in the picture are similar,
Their corresponding sides will be in the same ratio.
By applying this property,
[tex]\frac{20}{36}= \frac{30}{30+(x+5)}[/tex]
[tex]\frac{5}{9}= \frac{30}{x+35}[/tex]
5(x + 35) = 9 × 30
5x + 175 = 270
5x = 270 - 175
5x = 95
x = [tex]\frac{95}{5}[/tex]
x = 19
Jack did 3/5 of the problems on his weekend homework before Sunday. On Sunday, he solved 1/3 of what was left and the last 4 problems. How many problems were assigned for the weekend?
Answer:
15 problems were assigned for the weekend.
Step-by-step explanation:
Let x denote the number of problems assigned for the weekend.
Before Sunday, he did 3/5 of the problems, so he is left with (1-3/5)x = 2/5 x of the problems.
On Sunday, he solved 1/3 of what was left of the problems, so he is left with (1 - 1/3)(2/5 x) = (2/3) * (2/5) x = 4/15 x problems.
4/15 x equals 4 because those were the last remaining problems, so we can solve for x:
[tex]\frac{4}{15}x=4\\x = 4 \cdot \frac{15}{4} = 15[/tex]
So 15 problems were assigned for the weekend.
