Answer:
-2
Step-by-step explanation:
If triangle ABC has the following angle measurements, what is the set-up to solve for x?
∠A= 4x - 17
∠B= 3x + 8
∠C= x + 13
4x - 17 + 3x + 8 + x + 13 = 180
4x - 17 = 3x + 8 + x + 13
4x - 17 - 3x + 8 - x + 13 = 180
4x - 17 - 3x + 8 - x + 13 = 180
Answer:
A
Step-by-step explanation:
The answer is the first one. We've used that in previous questions.
B is wrong. It needs to be equal to something (180 in this case). B is also saying that the first angle is = to the sum of the other two. Not so.
C is wrong. the third angle's x term has to be plus.
D has the same problem.

16.8 is 10% of what number? Someone help TWT
Answer:
168
Step-by-step explanation:
16.8 = 10%
x = 100%
To get to 100%, you have to multiply 10 by ten and 16.8 by 10. Like this:
16.8 = 10% original equation
16.8 (10) = 10% (10) * both sides by 10
168 = 100% simplify

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. In a particular region of a national park, there are currently 330 deer, and the population is increasing at an annual rate of 11% a. Write an exponential function to model the deer population in terms of the number of years from now. B. Explain what each value in the model represents . . Predict the number of deer that will be in the region after five years. Show your work.
Answer:
Formula : V = I (1 + R)^T , Deers after 5 years ≈ 556
Step-by-step explanation:
Exponential formula for final value 'v' - for initial value 'i' at growth rate 'r' for a period of time 't'
V = I (1 + R)^T
As per given deer case, I = 330 & R = 11% = 0.11
V = 330 ( 1 + 0.11 )^t
Predicted deers after 5 years, V = 330 (1.11)^5
330 x 1.685 = 556.05

Jonas runs A store that sells guinea pigs he wants to ensure that he has more than 1 pound of dry food for every five guinea pigs he has in the store he currently has 8 pounds of dry food and wants to know how many guinea pigs can he have in the store right and solve the inequality to solve the problem what is the solution to the inequality
Answer:
x ≤ 40
Step-by-step explanation:
Pounds of food : number of guinea pigs
1 pound : 5 guinea pigs
8 pounds : x guinea pigs
Where,
x = number of guinea pigs at 8 pounds of food
Inequality:
1 : 5 ≤ 8 : x
1/5 ≤ 8/x

Answer:
C) 18 square units
Step-by-step explanation:
There are many ways to go about solving this. You could divide it into two triangles with a middle section. But it might be easier just to count the squares:
whole squares = 12
half squares = 4 (which equals 2)
3/4 square = 4
1/4 squares = 4
(add the 3/4 and 1/4 squares to equal 4)
12+2+4=18

Given the set of test scores: 42, 72, 74, 78, 80, 80, 85, 88, 92. If the outlier is removed, which statement is true? Select all that apply.
Choose all that apply:
The standard deviation decreases.
The mean increases.
The median decreases.
The range increases.
Answer:
Standard deviation decreases and mean increases
Step-by-step explanation:
The test scores are:
42, 72, 74, 78, 80, 80, 85, 88, 92
Mean = (42 + 72 + 74 + 78 + 80 + 80 + 85 + 88 + 92)/9 = 76.77
Median is 5th term which is 80
Range is highest score - lowest score = 92 - 42 = 50
Standard deviation from an online calculator gives 13.69
Now,we want to know what happens to those values when the outlier is removed. The outlier in this case is 42 because it is not consistent with other scores which range from 72 - 92.
Thus,the new set of scores are;
72, 74, 78, 80, 80, 85, 88, 92
New Mean = (72 + 74 + 78 + 80 + 80 + 85 + 88 + 92)/8 = 81.125
New Median will be the average of the 4th and 5th term which is (80 + 80)/2 = 80
New Range = 92 - 72 = 20
New Standard deviation from an online calculator gives 6.39
From the comparison above when the outlier is removed, we can say that;
- Mean increases
- remains the same
- Range decreases
- standard deviation decreases

#surfacearea
Answer:
773 or 278.5 (if it only wants the sides the pic shows)
Step-by-step explanation:
13*5=65
65/2=32.5 (since it is a triangle you by 2)
12*9=108
108/2=54
15*20=300 (it is a square so you leave it)
you do it on the other sides that you can't see in the pic.
Add all the numbers together: 32.5+32.5+54+54+300+300 or 32.5(2)+56(2)+300(2)=773

Graham graphs the following system of equations to determine its solution.
2x + 4y = 12
2x - y = 2
What is the correct solution?
Enter your answer by filling in the boxes.
(__,__)
ASAP plz
Answer: (2,2)
Step-by-step explanation:
I'm going to use substitution to solve this:
First, I use the second equation to solve for y in terms of x.
2x - y = 2
-y = 2 - 2x
y = 2x - 2
Then, I plug the value for y into the first equation:
2x + 4y = 12
2x + 4(2x - 2) = 12
2x + 8x - 8 = 12
10x - 8 = 12
10x = 20
x = 2
Now that we have x, we can plug it into either equation (I used the first) to get the value for y:
2x + 4y = 12
2(2) + 4y = 12
4 + 4y = 12
4y = 8
y = 2
We get the point (2,2) as a solution.
Note: This is the point where both lines intersect.
After solving the equation, the value of for the points x and y are (2, 2).
What is an equation?Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
As per the given equation in the question,
2x + 4y = 12 (i) and
2x - y = 2 (ii)
Solve the value for y,
5y = 10
y = 10/5
y = 2
Substitute y=2 in equation (i)
2x + 4(2) = 12
2x = 12 - 8
x = 4/2
x = 2
Therefore, the point is (2, 2).

It is given that set W = { x, y, z).
What is the subset of set W?
Answer:
Please check the explanation.
Step-by-step explanation:
Given the set W = {x, y, z}
If there are n elements in a set, then are 2ⁿ subsets.
As there are 3 elements in a set, then are 2³ or 8 subsets.
so
W = {x, y, z} has 8 subsets.
They are:
∅, {x}, {y}, {x}, {x, y}, {x, z}, {y, z}, and {x, y, z}
Please note that any subset of the set W = {x, y, z} contains all the elements which are also the elements of the set W = {x, y, z}what’s the difference between point A (3,4) and B (-1,4) on a coordinate plane?
