You buy a $90 item and it is discounted by $18. What is the discount's percentage?
Answer:
Hey the answer is 20%.
Step-by-step explanation:
You multiply the $90 with 20%,
but in order to figure that out you need to:
Calculate the savings: 20% of $90 = $18.
Subtract the savings from the original price to get the sale price: $90 - $18 = $72. You're all set!

what is 2(12) 3/2 in its simpilist form
Answer: 2/12 --> 1/6
3/2 --> 1 1/2
Step-by-step explanation:
2/12 can be simplified by dividing the top by 2 and the bottom by two. 2 is the GCF (greatest common factor) of both 2 and 12.
3/2 is a improper fraction so you have to make it a proper fraction. To do that you get 1 and 1/2. <-- this is for simplest form.
Hope this helped!

What percent is represented by the shaded area?
%
Answer:
70%
Step-by-step explanation:
Each blue line represents 10%. Since there are 7 blue lines, we just multiply 10% by 7 and we get 70%
Answer:
70%
Step-by-step explanation:
7 out of 10 rectangles were filled so that's 7/10. 7/10 also equals 70/100. Therefore it's 70 out of 100 or 70%.

a father is 27 years older than his son. ten years ago he was twice as old as his son. how old is the father
Answer:
thus the father is 64 years and son is 37years
Step-by-step explanation:
Let father be X and son be y
X=27+Y...........(I)
X-10=2(Y-10)
putting the value of X from eqn(I)
27+Y-10=2Y-20
Y+17=2Y-20
17+20=2Y-Y
37=y
X=27+Y
X=64

Vince bought 6 boxes of worms to use as bait while fishing with friends. if each person uses exactly 3/8 of a box of worms, how many people can share the worms?
We are given the following information:
each person uses 3/8 a box
there are 6 boxes
Because each box is , and there are 6 boxes, we know that 1 person is , or .
In order to find how many people can use the 6 boxes, we can divide it by 3 (for each use):
48 / 3 = 16
Therefore, 16 people can share the worms.
how many times larger is 1,000 than 1?
Answer:As 1,000 multiplied by 1 equals 1,000. So, 1000 is thousand times bigger than 1. For instance, 100 is 10 times bigger than 10.

Halp how to factor 4x-2
Answer:
2(2−1)
Step-by-step explanation:
4−2
Grouping
Common factor
4−2
2(2−1)
Solution
2(2−1)
To factor, you do the opposite of what you would in distributive property. You have to find the greatest common factor, or GCF, of 4 and -2.
4 2
------ -------
1 | 4 1 | 2
2 | 2
So the GCF is 2. Now we factor the expression.
4x-2
2(2x-1)

Answer:
[tex]A= 53[/tex]
Step-by-step explanation:
Given
[tex]BC = 9,6[/tex]
[tex]AC = 7.2[/tex]
Required: Angle A
This is calculated using:
[tex]tan\ A = \frac{Opposite}{Hypotenuse}[/tex]
From the attachment;
[tex]Opposite = 9.6[/tex]
[tex]Adjacent = 7.2[/tex]
So:
[tex]tan A =\frac{9.6}{7.2}[/tex]
[tex]tan A =1.333[/tex]
Take arctan of both sides
[tex]A= tan^{-1}(1.333[/tex]
[tex]A= 53[/tex]----- approximated

According to a recent poll, 25% of adults in a certain area have high levels of cholesterol. They report that such elevated levels "could be financially devastating to the regions healthcare system" and are a major concern to health insurance providers. According to recent studies, cholesterol levels in healthy adults from the area average about 260 mg/dL, with a standard deviation of about 35 mg/dL, and are roughly Normally distributed. Assume that the standard deviation of the recent studies is accurate enough to be used as the population standard deviation. If the cholesterol levels of a sample of 49 healthy adults from the region is taken answer parts (a) through (d). A) What is the probability that the mean cholesterol level of the sample will be no more than 210? B) What is the probability that the mean cholesterol level of the sample will be between 205 and 215? C) What is the probability that the mean cholesterol level of the sample will be less than 200?D) What is the probability that the mean cholesterol level of the sample will be greater than 222?
Answer:
The answer is below
Step-by-step explanation:
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\for\ a \ sample(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }\\\\where\ x=raw\ score,\mu=mean, \sigma=standard deviation[/tex]
Given that n = 49, μ = 260 mg/dL, σ = 35 mg/dL
a) For x < 210:
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{210-260}{35/\sqrt{49} } =-10[/tex]
From the normal distribution table, P(x < 210) = P(z < -10) = 0.0001
b) For x > 205:
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{205-260}{35/\sqrt{49} } =-11[/tex]
For x < 215:
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{215-260}{35/\sqrt{49} } =-9[/tex]
P(205 < x < 215) = P(-11 < z < -9) = P(z < -9) - P(z < -11) = 0.0001 - 0.00001 = 0.00009
c) For x < 200:
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{200-260}{35/\sqrt{49} } =-12[/tex]
From the normal distribution table, P(x < 200) = P(z < -12) = 0.00001
d) For x > 222:
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{222-260}{35/\sqrt{49} } =-7.6[/tex]
From the normal distribution table, P(x > 200) = 1 - P(z < -12) = 1 - 0.0001 = 0.9999
