Answer:
1 7/20
Step-by-step explanation:
So, you added the 15/20 and 12/20 to get 27/20
Then to simplify 27/20 you have to see how many times 27 can go into 20
27 can go into 20 with a remainder of 7 which then will lead you to the answer of 1 7/20 and you can't simplify it anymore.
Hopefully, that helps.

in each linear equation identify the slope (m) and the y-intercept (b)
Answer:
a is D and b is C
Step-by-step explanation:
Slope is always with an x, b is always alone
Hey there!
Please remember that
in slope-intercept form, m is the slope, and b is the y-intercept.Is y=4x-5 written in slope-intercept form (y=mx+b)? Sure! :)
Therefore, the slope, m, is 4, and the y-intercept, b, is -5.
Same with the second equation:
y=2/3-x
or
y=x-2/3
here, the y-intercept, b, is 2/3, and the slope, m, is -1.
Now, what's the equation of the line with a slope of 2 and a y-intercept of -7?
That's right, y=2x-7.
Hope everything is clear.
Let me know if you have any other questions!

Write an expression that represents the height of a tree that began at 6 feet an increases by 2 feet per year. Let y represent the number of years
Answer:
Yes.
Step-by-step explanation:
The expression 2y + 6 could be used to denote the tree's height.
What is an expression?A number, a variable, or a mixture of numbers and variables, along with operation symbols, make up an expression. Two expressions joined by an equal sign form an equation.
Given, the height of a tree that began at 6 feet and increases by 2 feet per year. Let y represent the number of years
Expression = 2y + 6
Since the height of the tree starts at 6 feet thus positive 6 would be constant and it increases by 2 feet every year thus 2 would be the multiple of the variable that is y.
therefore, an Expression that represents the height of the tree would be 2y + 6.

If
f(x) = ax + 6,
where a is a constant, and f(2) = 8, calculate a.
Provide your answer below:
Answer:
1
Step-by-step explanation:
f(x) = a(2) + 6 = 2a + 6
Given f(2) = 8
so 2a + 6 = 8
2a = 8 - 6 = 2
so a = 1

Answer:
105
Step-by-step explanation:
Assuming A^2 + B^2 = C^2:
C^2 = 4 + 3 = 7
So,
C^2 * 15 = 49(15) = 105
Note: Since the relationship between A, B, and C isn't known, it cannot be said for certain that 105 is the answer.
Step-by-step explanation:
there is no C in the first 2 equations. There is no A or B in the last expression. I do not think you can solve this.

The graph of f(x) shown below
Answer:
C
Step-by-step explanation:
the "-" sign can't be true, because that would have turned the whole graph of x² upside-down. but it is not.
so, we need a positive sign for the x term.
and the whole graph is shifted to the right. so the functional value of x of F(x) is now the same that happened "earlier" (for smaller x) with G(x). so, the argument "x" is now reduced (by 3 units, as the graph is shifted right by 3 units) in the calculation compared to the original G(x) calculation.
therefore, the ...(x-3)... expression is right.
so, positive sign and "(x-3)" is only in C.

A piñata is a container filled with candy and is broke by hitting it with a stick. The probability that Amanda will break a piñata on her first his is 0.58. She will continue to hit the piñata until it breaks. If she does not break the piñata on a particular hit, the piñata is weakened and the probability that she will break it on the next hit is 0.14 greater than the probability on the previous hit. For example, if the piñata does not break on the first hit, the probability that it will break on the second hit is 0.72 (found by 0.58 + 0.14 = 0.72). Calculate the probability that Amanda does not break the piñata on the first hit and does break the piñata on the second hit
Answer:
0.3024
Step-by-step explanation:
Given the following :
Probability of breaking pinata on first hit = 0.58;
P(first hit break) = 0.58
P(does not break on first hit) = 1 - p(first hit break) = 1 - 0.58 = 0.42
P(2nd hit break) = p(first hit break) + 0.14 = 0.58 + 0.14 = 0.72
Hence, Calculate the probability that Amanda does not break the piñata on the first hit and does break the piñata on the second hit
P(does not break on first hit) * p(2nd hit break)
0.42 * 0.72 = 0.3024

Step-by-step explanation:
Jerry, Skyler and Kyle were measuring the tank (cylinder) for storing water tower on the hill. Working together Jerry and Skyler
determine the circumference was approximately 295.3 feet. Kyle measured the height to be about 40 feet. What is the potential
volume of the tank? (Round to the nearest tenth)
Answer?
Answer:
277 591.1 ft³
Step-by-step explanation:
First, use the formula for circumference to solve for the diameter.
Circumference = πd
295.3 = πd
295.3/π = d
94 ft = d
Then, divide the diameter by 2 to find the radius.
r = d/2
r = 94/2
r = 47 ft
Now, use the value of the radius with the given height in the formula for volume of a cylinder.
V = πr²h
V = π(47²)(40)
V = 277 591.1 ft³

10. Multi-Step The paleontologist measures the fossils again and finds two errors. Two fossils with a length of 7.9 centimeters instead measure 8.1 and 8.2 centimeters. Which two numbers will have the same number of dots? A) 7.8 and 7.9 (В 8.0 and 8.2 © 7.8 and 8.1 D 7.9 and 8.1
The two numbers on the dot plot that will have the same number of dots would be: B. 8.0 and 8.2.
What is a Dot Plot?A dot plot can be described as a simple form of data visualization that shows the frequency at which each data points in the data set occurs, which are plotted as dots.
The data set of the measures of the fossils taken by the paleontologist include the following data points and the frequency at which they occur and how they are represented on a dot plot:
7.8 - 5 times (5 dots)7.9 - 6 times (6 dots)8.0 - 0 times (0 dot)8.1 - 3 times (3 dots)8.2 - 1 times (1 dot)We are told that the paleontologist found two errors, where a length of two fossils that measure 7.9 are recorded as 8.1 and 8.2.
Therefore, if the correct measures are used to draft a new dot plot, we would have the following data points and number of dots representing the correct frequency of each measures:
7.8 - 5 times (5 dots)7.9 - 8 times (8 dots)8.0 - 0 times (0 dot)8.1 - 2 times (2 dots)8.2 - 0 times (0 dot)Therefore, the two numbers on the dot plot that will have the same number of dots would be: B. 8.0 and 8.2.
