Which is a factor pair of 72?
12,6
14,5
23,4
24, 2
Answer:
12,6
Step-by-step explanation:
The factor pair of 72 is 12 and 6 because, factors are the 2 numbers you multiply together to get the product. In this case, the product is 72. 12x6=72 So therefore, 12 and 6 are the factors of 72. You can figure this out simply by multiplying 12 and 6 together.
The factor pairs of 72 are (1,72), (2,36), (3,24), (4,18), and (6,12).
Explanation:To find the factor pairs of 72, we need to find pairs of numbers that multiply together to give us 72. Let's list all the factors of 72 and check which pairs multiply to give us 72:
1 x 72 = 722 x 36 = 723 x 24 = 724 x 18 = 726 x 12 = 72So, the factor pairs of 72 are (1, 72), (2, 36), (3, 24), (4, 18), and (6, 12).

3 parts: List the ratios for using angle A as the angle of reference reduce when necessary
Sin A= Cos A= Tan A=
Answer:
[tex]\sin{A}=21/29\\\cos{A}=20/29\\\tan{A}=21/20[/tex]
Step-by-step explanation:
The sine of an angle in a right triangle is the ratio of the side across from the angle with the hypotenuse of the triangle (the hypotenuse is the side across from the right angle). In this case, the sine of angle A, shortened to [tex]\sin{A}[/tex], is [tex]21/29[/tex].
Cosine is short for "complementary sine." If the angles A + C = 90, the cosine of A is equal to the sine of C, since A and C are complementary. So [tex]\cos{A}=\sin{C}=20/29[/tex]. Notice that this ratio is the same as the ratio of the side adjacent to angle A (AB), to the hypotenuse.
The tangent is the ratio of the side opposite an angle to the side adjacent to it. Here, [tex]\tan{A}=21/20[/tex]. So, our trig ratios for this angle are
[tex]\sin{A}=21/29\\\cos{A}=20/29\\\tan{A}=21/20[/tex]

The gas tank in Feliz's car is full. Each time he drives to or from work, he uses 1 of a full
tank of gas. Which equation represents the number of times Feliz can drive to or from work
with the gas in his tank?
Answer: number of times feliz can drive to or from work with the gas in his tank is 10 times
Step-by-step explanation:
Let's start by reviewing the slope-intercept formula:
y = mx + b
At the start of the journey, we have a tank that's 5/6 full and have yet to go anywhere. That means that our b is 5/6.
Thus:
y = mx + 5/6
Now, every time he drives to or from work, be loses 1/12 of a full tank.
Thus;
y = -(1/12)x + 5/6
negative because the initial volume of gas is decreasing whenever he goes out.
Now, to get the number of times feliz can drive to or from work with the gas in his tank, y = 0.
Thus,
0 = -(1/12)x + 5/6
Add (1/12)x to both sides to give;
(1/12)x = 5/6
x = 5/6 ÷ 1/12
x = 10

Write and solve an inequality to find the values of x for which the perimeter of the rectangle is less than 120.
A rectangle has a width of x and a length of x plus 4.
Answer:
Inequality : 4x+8 < 120
x<28
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Perimeter of a rectangle (P)= 2 length +2 width
Where:
Width = x
Length = x+4
Replacing with the values given
P = 2 (x+4) + 2x
P = 2x+8+2x
P=4x+8
Since the perimeter of the rectangle must be less than 120:
4x+8 < 120
Solving for x
4x<120-8
4x<112
x<112/4
x<28
Feel free to ask for more if needed or if you did not understand something.
To find the values of x for which the perimeter of a rectangle is less than 120, you would solve the equation 2*(x + (x+4)) < 120. After simplifying and solving, the result is x < 28.
Explanation:In this problem, you are asked to find the values of x for which the perimeter of a rectangle is less than 120. The rectangle has width of x and a length of x plus 4.
The perimeter of a rectangle is defined as 2*(length + width). Plugging the lengths in for our rectangle, we get 2*(x + (x+4)) < 120. Simplifying this inequality gives 2*(2x + 4) < 120
From there, you want to distribute the 2 across the equation, which gives 4x + 8 < 120. Subtract 8 from both sides to get 4x < 112, and then divide both sides by 4 to find x < 28. So, the possible values of x are those less than 28.

If the APR of a savings account is 4.8% and interest is compounded monthly,
what is the approximate APY of the account?
O A. 1.05%
O B. 10.49%
O C. 4.91%
O D. 4%
Answer:
C. 4.91%
Step-by-step explanation:
The effect of frequent compounding is to increase the nominal interest rate by a small factor. For interest rates in a practical range (<20%/year), the effective increase in rate will be approximately half the original interest rate.
ApproximationFor an interest rate of 4.8%, we expect the compounding to increase it by less than 2.4%. The maximum effective rate due to compounding is approximately (4.8%)(1 +2.4%) ≈ 4.91%.
Exact computationFor nominal annual rate r compounded n times per year, the effective annual rate is ...
r' = (1 +r/n)^n -1
For r = 0.048 and n = 12, this becomes ...
r' = (1 +0.048/12)^12 -1 = 1.004^12 -1 ≈ 1.049070208 -1 ≈ 4.91%
__
Additional comment
After you have worked with interest compounding for a bit, you realize compounding increases the effective rate by a small amount. That means the value will be more than 4.8% (eliminating choices A and D), but certainly will not be as high as 10% (eliminating choice B). The only reasonable choice is C, which happens to be the correct one.
Which function is linear?
A). f(x) = |7x| + 2
B). f(x) = 1/7x + 2
C). f(x) = 7x − 2
D). f(x) = |7x| − 2
Answer:
C
Step-by-step explanation:
Option C is the only one that's linear because it follows all of the rules for a line to be linear. To check, use the process of elimination:
A). When x is an absolute value, the line will not be linear because an input will have two outputs.
B). x cannot be in the denominator of a fraction for the line to be linear
D). Once again, x cannot be an absolute value.
*Note: I'm assuming in option B, 7x is in the denominator and 1 is in the numerator. If the fraction is simply 1/7 multiplied by x, it is linear along with C.

Fatima opens an account with 1300 that earns 3.5% interest, compounded monthly. How long will it take the account value to be $2500?
Answer:
The formula to calculate the account value in future (compounded monthly):
A = Principal x (1 + rate/12)^(month)
=> 2500 = 1300 x (1 + (3.5/100)/12)^(month)
=> (1 + 0.00291)^(month) = 2500/1300
=> 1.00291^(month) = 1.923
=> month = log(1.923)/log(1.00291) = 225
=> It will take 225 months to have 2500 dollar in account.
Hope this helps!

You have a rectangular garden that is 10 feet
wide and 15 feet long. You want to increase
the garden so that each side is twice as long
as they are now.
a. What will be the area of the
new garden?
b. Will the area of the new garden be
twice as large as it is now? Explain.
a. If you double both sides, you'll get a rectangle with dimensions 20 feet wide and 30 feet long, therefore the area will be 20 × 30 = 600 feet².
b. The area of the old rectangle was 10 × 15 = 150 feet², so no the area is not twice as large, it is 4 times as large. This is because if the area is base × height, then doubling both of these gets you (2 × base) × (2 × height) = 4 × (base × height).

What is the mean absolute deviation of the data set? 8, 5, 12, 4, 5, 8, 7 1 2 5 7
The mean absolute deviation (MAD) is a measure of the spread of a data set, calculated as the average of the absolute deviations of each data point from the data set's mean. For the given data set, the MAD is approximately 2.42.
The mean absolute deviation (MAD) of a data set is a measure of variability that represents the average difference between each data point and the mean of the data set. To calculate MAD, follow these steps:
Calculate the mean (average) of the data set.Calculate the deviation of each measurement, which is the absolute value of the difference between each measurement and the mean.Sum all the absolute deviations.Divide the sum by the number of data points in the data set to get the MAD.For the data set 8, 5, 12, 4, 5, 8, 7, 1, 2, 5, 7, the mean is 5.8 (sum of all numbers divided by the number of numbers). Here are the deviations from the mean:
|8 - 5.8| = 2.2|5 - 5.8| = 0.8|12 - 5.8| = 6.2|4 - 5.8| = 1.8|5 - 5.8| = 0.8|8 - 5.8| = 2.2|7 - 5.8| = 1.2|1 - 5.8| = 4.8|2 - 5.8| = 3.8|5 - 5.8| = 0.8|7 - 5.8| = 1.2Summing all the absolute deviations gives us 26.6. With 11 data points, the MAD is 26.6 / 11 = 2.42.

An above-ground rainwater tank is rectangular and has a length of 15
feet and a height of 2 feet. It will hold 375 cubic feet of water. What is the
height of the rainwater tank?
Answer:
The width of the tank is 12.5 feet
Step-by-step explanation:
We need to find the width, not height of the rainwater tank, since the height is already given.
The volume of a rectangular prism is given as:
V = L * W * H
where L = length of the tank
W = width of tank
H = height of tank
We have its volume as 375 cubic feet and the length, L, as 15 feet and height, H, as 2 feet.
Therefore, its width is:
375 = 15 * W * 2
375 = 30W
=> W = 375 / 30
W = 12.5 feet
The width of the tank is 12.5 feet.
