Answer:
Charles: 17 points
Adam: 25 points
Bethany: 30 points
Answer:
Adam scored 25 points.
Bethany scored 30 points.
Charles scored 17 points.
Step-by-step explanation:
A = Adam, B = Bethany, C = Charles
What we know:
C + 8 = A
A + 5 = B
A + B + C = 72
Charles:
C + 8 + 5 = B
C + (C + 8) + (C + 13) = 72
72 - 8 - 13 = 51
51/3 = 17
Charles scored 17 points.
Bethany:
17 + 13 = 30
Bethany scored 30 points.
Adam:
17 + 8 = 25
Adam scored 25 points.

Carmen creates the ratio table below based on one 8-ounce serving of juice
How many total calories will 4 servings of juice contain?
A) 420
B) 520
C) 650
D) 780
Answers
Answer:
B
Step-by-step explanation:
The pattern is adding 130, or multiply the servings by 130.
so if 3x=390, you would divide both sides by 3 and get 130.
This means that x=130
Now plug in 4x=?
You would get 4*130=?
if you do the math through multiplication you would get 520

What is the inverse of function f? f(x)=10/9r+11
Answers
[tex]f(x) = \frac{10}{9}x + 11 \\ [/tex]
So :
[tex]y = \frac{10}{9}x + 11 \\ [/tex]
Subtract the sides of the equation minus 11
[tex]y - 11 = \frac{10}{9}x \\ [/tex]
Multiply the sides of the equation by 9
[tex]9(y - 11) = 10x[/tex]
[tex]9y - 99 = 10x[/tex]
Divided the sides of the equation by 10
[tex] \frac{9y - 99}{10} = x \\ [/tex]
So :
[tex] {f}^{ - 1}(x) = \frac{9x - 99}{10} \\ [/tex]

Which expression is equivalent to cos(103°)cos(54°) – sin(103°)sin(54°)?
sin(49°)
cos(49°)
sin(157°)
cos(157°)
Answers
Answer:
D - cos(157)
Step-by-step explanation:
Cos sum angle identity
cos(A+B) = cosAcosB - sinAsinB
103+54=157
The correct answer to the question is Cos 157
There are two ways to solve this question:
Method 1:Evaluate: Cos103Cos54 – Sine103Sine54
This can be obtained as follow:
Cos103Cos54 – Sine103Sine54
= –0.1322 – 0.7883
= –0.9205Next, we shall evaluate each option given in the question to see which will be equivalent to –0.9205. This is illustrated below:
Sine 49 = 0.7547
Cos 49 = 0.6561
Sine 157 = 0.3907
Cos 157 = –0.9205From the above evaluation, we can see that Cos 157 is equivalent to Cos103Cos54 – Sine103Sine54
Thus, Cos 157 is the correct answer to the question.
Method 2Again, we can apply the addition formula from trigonometry.
Cos (A – B) = CosACosB + SineASineB
Cos (A + B) = CosACosB – SineASineB
Sine (A + B) = SineACosB + SineBCosA
Sine (A – B) = SineACosB – SineBCosA
Comparing
Cos103Cos54 – Sine103Sine54 with the formula given above, it is very clear that:
Cos103Cos54 – Sine103Sine54 = Cos(103 + 54)Cos103Cos54 – Sine103Sine54 = Cos 157
Recall:
Cos103Cos54 – Sine103Sine54 = –0.9205
Cos 157 = –0.9205
Therefore, Cos 157 remains the correct answer to the question.

How does 8 × 2 1 3 compare to 8? A) Less than 8 because you are multiplying by number less than 1. B) Greater than 8 because you are multiplying by a number less than 1. C) Less than 8 because you are multiplying by a number greater than 1. D) Greater than 8 because you are multiplying by a number greater than 1.
Answers
Answer:
Greater than 8 because you are multiplying by a number greater than 1.
Step-by-step explanation:
When 8 is multiple by another number, say x, the product is;
I) less than 8 if x<1
ii) equal to 8 if x=1
iii) greater than 8 if x> 1
Since 213 is greater than 1,then the product of 8 × 2 1 3 is greater than 8.

In the diagram shown below, Points M, N and P are collinear. If MN = 3x-9, NP = x+1 and MP= 6x-22, solve for the value of X (Answer notation: x=__)
Answers
Answer:
The value of x is 7
Step-by-step explanation:
M, N and P are collinear means they lie on the same line.
Mathematically;
MP = MN + NP
Thus;
6x-22 = 3x -9 + x + 1
6x-22 = 4x -8
6x -4x = -8 + 22
2x = 14
x = 14/2
x = 7

c. should have solved the equation a + 18 = -17
d. correctly substituted and evaluated the polynomial)
Answers
Answer:
Step-by-step explanation:
Correct steps to find the value of 'a' should be,
Braulio's synthetic division should be,
-1 | 1 5 a -3 11
-1 -4 (4 - a) (a - 1)
1 4 (a - 4) (1 - a) (a + 10)
Here remainder is (a + 10).
So (a + 10) = 17 ⇒ a = 7
Braulio Incorrectly found a value of 'a' because he should have used (-1) instead of 1.
Zahra's calculation by remainder theorem should be,
p(x) = x⁴ + 5x³ + ax² - 3x + 11
p(-1) = (-1)⁴ + 5(-1)³ + a(-1)² - 3(-1) + 11
= 1 - 5 + a + 3 + 11
= (a + 10)
Since, remainder of the solution is 17,
(a + 10) = 17 ⇒ a = 7
Zahra incorrectly found the value of 'a' because she incorrectly solved the powers to (-1).
Answer: incorrectly, should have used -1 instead of 1
incorrectly, incorrectly applied the powers to -1
