Question 11
The mean of five numbers is 16.
When two extra numbers are included the mean of the seven numbers is 20.
Find the mean of the two extra numbers.
Answer:
30
Step-by-step explanation:
The mean of 5 numbers is 16 => the sum is 16 x 5 = 80
The mean of 7 numbers is 20 => the sum is 20 x 7 = 140
So, the sum of the 2 extra numbers is 140 - 80 = 60
And the mean will be 60 : 2 = 30

see "additional comment" regarding listing pairs
Step-by-step explanation:
There are a number of ways angles can be identified as congruent. In each case, the converse of the proposition is also true.
opposite angles of a parallelogram are congruentcorresponding angles where a transversal crosses parallel lines are congruentalternate interior angles where a transversal crosses parallel lines are congruentvertical angles are congruentany two angles with the same measure are congruentIn these exercises, pairs of angles need to be examined to see which of these relations may apply.
__
ALeft
ABCD is a parallelogram, so the congruent angles are opposite angles and any that are vertical or corresponding:
∠BAC ≅ ∠BDC ≅ ∠EDF ≅ 110° (3 pairs)
∠ACD ≅ ∠ABD ≅ ∠BDE ≅ ∠CDF ≅ 70° (6 pairs)
Center
∠1 ≅ ∠4 ≅ 66° (1 pair) . . . . vertical angles
∠2 ≅ ∠3 ≅ ∠5 ≅ ∠6 ≅ 57° (6 pairs) . . . . marked with the same measure, and their vertical angles
Right
Assuming that lines appearing to go in the same direction actually do go in the same direction, the only pair of congruent angles in the figure is ...
∠2 ≅ ∠3
__
BLeft
Corresponding angles in congruent triangles are congruent. Here, the congruent triangles are ΔACD ≅ ΔCAB. So, the pairs of congruent angles are ...
∠ACD ≅ ∠CAB (30°)
∠CDA ≅ ∠ABC (90°)
∠DAC ≅ ∠BCA (60°)
Right
The corresponding angles and any vertical angles are congruent. This means all the odd-numbered angles in the figure are congruent, and all the even-numbered angles in the figure are congruent. The marked 72° angles show the "horizontal" segments are parallel by the converse of the corresponding angles theorem.
∠1 ≅ ∠3 ≅ ∠5 (72°) (3 pairs)
∠2 ≅ ∠4 ≅ ∠6 (108°) (3 pairs)

Additional comment
The question asks you to list pairs of congruent angles. When 3 things are congruent, they can be arranged in 3 pairs:
a ≅ b ≅ c ⇒ (a≅b), (a≅c), (b≅c)
Similarly, when 4 things are congruent, they can be arranged in 6 pairs:
a ≅ b ≅ c ≅ d ⇒ (a≅b), (a≅c), (a≅d), (b≅c), (b≅d), (c≅d)
In the above, we have elected not to list all of the pairs, but to list the set of congruences from which pairs can be chosen.
What is the measure of angle C in the following pentagon?
Answer:
122
Step-by-step explanation:
The sum of interior angles of a pentagon is 540. The angles we have are 105, 86, 137, and 90. This means that if you subtract those from 540, you get 122.

Answer:
[tex]c=35r+10[/tex]
Step-by-step explanation:
We need to create a linear equation in the form: c = mr + b
(where m is the slope and b is the y-intercept)
Choose two ordered pairs from the table: (2, 80) and (4, 150)
Let [tex](r_1,c_1)[/tex] = (2, 80)
Let [tex](r_2,c_2)[/tex] = (4, 150)
Calculate the rate of change (slope of linear equation) by dividing the change in c by the change in r:
[tex]\textsf{slope} \ m=\dfrac{c_2-c_1}{r_2-r_1}=\dfrac{150-80}{4-2}=35[/tex]
Now use point-slope form of linear equation to create final equation:
[tex]c-c_1=m(r-r_1)[/tex]
[tex]\implies c-80=35(r-2)[/tex]
[tex]\implies c=35r+10[/tex]

DeShawn is 38 years old and is married with 3 children, ages 2, 4, and 6. He makes $45,000 a year and is planning to retire when he turns 60. From the following three options, DeShawn decides to buy the $900,000 20 year term policy. Given DeShawn’s scenario, assess whether DeShawn made a wise decision. Annual life insurance premium (per 1,000 dollars of face value) for age 38. A 20-year term for male is 15 dollars and 38 cents, and for female is 14 dollars and 88 cents. Whole life: for male is 22 dollars and 40 cents, female is 20 dollars and 4 cents. 20-year endowment: male is 30 dollars and 5 cents and female is 29 dollars and 63 cents. A. DeShawn would be safer buying whole life policy. B. DeShawn would have more money in the long run if he invested in the 20-year endowment. C. DeShawn’s current policy will cover his family for an adequate period of time at his current salary. D. DeShawn’s current policy has too high of a face value and does not cover his family long enough. Please select the best answer from the choices provided A B C D.
Answer is C I took the quiz
The correct answer to Deshawn's decision is; C: DeShawn's current policy will cover his family for an adequate period of time at his current salary.
What is the benefit of the pension Policy?From the scenario in the question about the policy chosen by DeShawn, we can say that DeShawn made a good decision. This is because his current policy will cover his family for an adequate period of time at his current salary.
Now, it must be noted that the premiums are nominal and as such he will earn a good salary which will help to cover all the expenses and premiums.

Is the triangle a right triangle? Justfify.
Answer:
yes; AB ⊥ BC
Step-by-step explanation:
If the triangle is to be a right triangle, the slopes of two sides must be opposite reciprocals. The slope is the ratio of rise to run.
mAB = rise/run = -3/4
mBC = rise/run = 4/3
These slopes, -3/4 and 4/3 are opposite reciprocals (their product is -1), so ...
AB ⊥ BC . . . the triangle is a right triangle

Let f(x)=−2x+3f(x)=-2x+3. Find each of the following:
f(a)=f(a)=
2f(a)=2f(a)=
f(2a)=f(2a)=
f(a+2)=f(a+2)=
f(a)+f(2)=f(a)+f(2)=
Answer:
1. f(a) = -2a + 3
2. 2f(a) = -4a + 6
3. f(2a) = -4a + 3
4. f(a+2) = -2a - 1
5. f(a) + f(2) = -2a + 2
Step-by-step explanation:
for each one, just plug whatever is inside the parentheses inside the equation as x. For example, f(a) = -2(a) + 3. The a replaces all the x's

Ray hired a moving company to help him move to a new apartment. The equation below.
represents the relationship between the number of hours it takes to move (x) and the total cost
to move (y).
- 100 = 240x - 2y
What is the cost per hour?
Answer:
$120/hr
Step-by-step explanation:
if x is hours to move and y is total cost, let's rearrange the equation so that it is easier to understand. I'd say isolate y (total cost) and see what it is equal to:
- 100 = 240x - 2y
2y = 240x + 100
y = 120x + 100
What I see is: Total Cost = 240*(Hours to move) + 100
That tells us that each hour is $120. It also discloses that there appears to be an upfront charge of $100, before any work is done( even at 0 hours). [If the movers come to the apartment, but you've changed your mind, then it still costs $100].
It also tells us that the charge per hour is $120. [If I had a pickup, I'd do it for $100/hour, but my tiny Honda Accord trunk barely holds the spare tire.]
