First, we need to understand that these two triangles are
similar.
we know this because their lines (the arrows) prove they are the same direction. A similar triangle does
NOT mean they are proportional,
they are just similar by ratio.
Lets call the triangle on the left ABC and the triangle on the right A'B'C'.
I will attach an image of the labels.
Because they are similar triangles, angle A is the same as angle A'. Angle B is the same as angle B', angle C is the same as angle C'.
Based on that information, we know xº is = 65º. We know that the interior angles add up to 180º. So for triangle A'B'C', we can do 180º-40º-65º which is 70º. This means angle C' is 70º.
Now the important part is getting yº. A line is 180º. That means that 180º-70º=yº which is 110º.
If you do not understand anything, please let me know and I will try to teach you.

What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In item a, the arrow is 2/10 of the way from 60 to 70, hence the number is:
60 + 0.2(70 - 60) = 60 + 2 = 62.
In item b, the arrow is 8/10 of the way from 8 to 9, hence the number is:
8 + 0.8(9 - 8) = 8.8.
In item c, the arrow is 3/10 of the way from 2.5 to 3.5, hence the number is:
2.5 + 0.3(3.5 - 2.5) = 2.8.

Answers
The null hypothesis is that the proportions are 0.30, 0.20, 0.20, 0.20, 0.10 and the alternative hypothesis is that the proportions are not as given above.
How to illustrate the information?It should be noted that the null hypothesis is the theory that states that there is no statistical relationship between the variables.
In this case, the Chi square test can be run to get the desired information. Therefore, X² was gotten as 19.597. The degree of freedom is 4 and the p value is 0.0006 from the distribution table.
In this case, the critical value of 0.006 is less than the 0.05. Therefore, we need to reject the null hypothesis.
This implies that there's evidence that the distribution doesn't correlate with what we've.

If f(x) = x2 – 2x and g(x) = 6x + 4, for which value of x does (f + g)(x) = 0?
Answers
hi
f(x) = x² -2x
g(x) = 6x+4
(f+g) (x) = x²-2x +6x+4 = x²+4x +4 = (x+2)² = (x+2) (x+2)
(f+g) (x) = 0 means = (x+2) (x+2) = 0
so x+2 = 0
x = -2
(f+g) (x) = 0 for x = -2
The x-intercept of a line is 2 and the y-intercept is 4. Explain how to use this information to write the equation of the line.
Answers
Answer:
y = -2x + 4
Step-by-step explanation:
The x-intercept would be the point (2,0) and the y intercept would have the point (0,4). Once we know two points we can write the equation in the line intercept for of y = mx + b.
We need to find the slope and the y intercept. The slope is the steepness of the line and it is the change in y over the change in x.
The ordered pairs are written in the form of (x, y). From our two points, we will subtract the y's to find the top number of our fraction.
0 - 4 = -4 that is the numerator (top number) of our slope. We do the same with the two x numbers that we have been given.
2 - 0 = 2 This is our numerator (or bottom number of our slope)
Our slope is -4 /2 to simplify, we divide the top and bottom number by 2 to get -2 / or just -2
Now that we have the slope we need to find the y-intercept. We can use either of our original two points and our slope to determine the y-intercept. It does not matter if you use the point (2,0) or (0,4). I will use (2,0) and the slope of -2
y = mx + b
0 = -2(2) + b
0 = -4 + b add 4 to both sides of the equation
4 = b
Now that we have the slope and the y-intercept, we can write the equation
y = mx + b
y = -2x + 4

Compute the monthly payments for each add-on interest loan. The amount of the loan is $1150. The annual interest rate is 6%. The term of the loan is 4 years.
Answers
The monthly payments for each add-on interest loan will be $29.71.
Given Information and Formula Used
Principal Amount, P = $1150
Rate of Interest, R = 6%
Duration of loan in years, T = 4
The formula for simple interest is given as,
I = (P × R × T)/100
Calculating the Add-On Interest For Each Month
Interest, I = (P × R × T)/100
Substituting the values of P, R, and T in the above formula, we get,
I = $ (1150 × 6 × 4)/100
I = $ 27600/100
I = $276
Calculating the Total Monthly Payment With Interest
Amount of add-on interest loan, A = P + I
A = $1150 + $276
A = $1,426
Monthly payment with interest = A/(4×12)
= $ 1426/48
= $29.71
Hence, the monthly payments for each add-on interest loan would be $29.71.
