The area of the figure is
square units.
Which is equivalent to 5(a + 6)?
1. a+30
2. 5a-30
3. 5a+6
4. 5a+30
Answer: the answer is number four.
Step-by-step explanation:
because when you take five multiply by A (5*a) you will get 5a and when you take five multiply by six (5*6) you will get 30 and there is positive sign so the plus (+) stays the same and your will be (5a+30) that is your answer. good luck.What is the best way to describe |-2| On a number line

solve the equation -3 + 1/2n = 1/2 (-n + 14) in two different ways.
Answer:
Step-by-step explanation:
-3 + 1/2n = 1/2 (-n + 14)
distribute
-3 + 1/2n = -1/2n + 7
-1/2n
cancel out -1/2n
-3 = n + 7
-10 = n
subtract 7
n = -10

Two Social Security numbers (see Exercise 8.12) match zeros if a digit of one number is zero iff the corresponding digit of the other is also zero. In other words, the zeros in the two numbers appear in exactly the same position. For example, the Social Security numbers 120-90-1109 and 430-20-5402 have matching zeros.
Prove: Given a collection of 513 Social Security numbers, there must be two that match zeros.
Answer:
Proved
Step-by-step explanation:
From the given parameters, we have:
[tex]n = 9[/tex] i.e. the length of each security numbers
[tex]r = 2[/tex] i.e. 2 security numbers
Required
In 513 security numbers, 2 must have matching zeros
To do this, we make use of Pigeonhole principle.
First, we calculate the number of all security numbers not having matching zeros.
Each of the 9 digits can be selected in 2 ways.
2 ways implies that each digit is either 0 or not
So, total selection is:
[tex]Total = 2^9[/tex]
[tex]Total = 512[/tex]
Apply Pigeonhole principle
The principle states that: suppose there are n items in m containers, where [tex]n>m[/tex], then there is at least one container that contains more than 1 item.
This means that if there are 512 security number without matching zeros, then there is 1 (i.e. 512 + 1) with matching zeros.
[tex]512 + 1 = 513[/tex]

Find the total surface area of the
following cylinder:
r = 5 cm
5 cm
SA = [ ? ]n cm2
Leave your answer in terms of t.
Enter the number that goes in the green box.
Answer:
100Step-by-step explanation:
Given ,
Radius of the cylinder = 5 cm
Height of the cylinder = 5 cm
Therefore,
Total surface area of the cylinder
[tex] = 2\pi r(r + h)[/tex]
[tex] = 2\pi \times 5(5 + 5) {cm}^{2} [/tex]
[tex] = 10\pi \times 10 {cm}^{2} [/tex]
[tex] = 100\pi {cm}^{2} [/tex]
Hence,
The required value to put in the green box is 100(Ans)
Based on the components of the given vectors match each vector subtraction with graph of the resulting vector
Answer: graph 1 —> u-v
graph 2—> u-w
graph 3—> w-v
graph 4—> v-u
*Look at both pictures to make sure this is for your specific question
Step-by-step explanation: I got this right on Edmentum
Graph 1 represents the vector u - v, graph 2 represents the vector u - w, graph 3 represents the vector w - v, and graph 4 represents the vector v - u.
What a is vector?It is defined as the quantity that has magnitude as well as direction also the vector always follows the sum triangle law.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have vectors u, v, and w given in the picture:
u = <-2, -7>
v = <3, -4>
w = <5, 1>
= u - v
= <-2, -7> - <3, -4>
= <-5, -3>
= u - w
= <-2, -7> - <5, 1>
= <-7, -8>
= w - v
= <5, 1> - <3, -4>
= <2, 5>
= v - u
= <3, -4> - <-2, -7>
= <5, 3>
Thus, graph 1 represents the vector u - v, graph 2 represents the vector u - w, graph 3 represents the vector w - v, and graph 4 represents the vector v - u.

Given: ()=5−2. Find: (+2)
Answer: The value of [tex]g(a+2)=5a-8[/tex].
Step-by-step explanation:
We are given that,
[tex]g(x)=5x-2[/tex] ...(i)
To find: [tex]g(a+2)[/tex]
Substitute [tex]x=a+2[/tex] in (i), we get
[tex]g(a+2)=5(a+2)-2\\\\g(a+2)=5a+10-2\\\\g(a+2)=5a+8[/tex]
Therefore, the value of [tex]g(a+2)=5a-8[/tex].

You are planning on applying to the Knirhsdaeh institute as a psychology counselor. They hire millions of psychologists around the world. You know the standard deviation for the salaries is $13 k. To find the average, you sample 23 random employees and get an average salary of $81 k. Find an 98% confidence interval for the true average salary of Knirhsdaeh employees.
Answer:
The 98% of the confidence interval for the true average salary of Knirhsdaeh employees as a psychology counselor
(75.4206, 86.5794)
Step-by-step explanation:
Step(i):-
Given that the mean of the sample = $81 k
Given that the size of the sample 'n' = 23
Given that the standard deviation for the salaries is $13 k
Step(ii):-
98% of the confidence interval for the true average salary of Knirhsdaeh employees is determined by
[tex](x^{-} - t_{0.02} \frac{S.D}{\sqrt{n} } , x^{-} + t_{0.02} \frac{S.D}{\sqrt{n} })[/tex]
Degrees of freedom = n-1 = 23-1 =22
[tex]t_{0.02} = 2.5083[/tex]
[tex](81 - 2.0583 \frac{13}{\sqrt{23} } , 81 + 2.0583 \frac{13}{\sqrt{23} } )[/tex]
( 81 - 5.57940 , 81 + 5.57940)
(75.4206, 86.5794)
Final answer:-
The 98% of the confidence interval for the true average salary of Knirhsdaeh employees as a psychology counselor
(75.4206, 86.5794)

At the book fair, Vald spends all of his money on new books. Pamela spends
2/3 as much as Vald. Eli spends 4/3 as much as Vald. Who spent the most?
The least?
Step-by-step explanation:
Lets take Vald spends $100 on the book fair which are all the money he had.
Pamela Spends 2/3 as much as Vald
Pamela Spends 2/3 x 100 = $66.67
Eli Spends 4/3 as much as Vald
Eli spends 4/3 x 100 = $133.33
From here, we can see Eli Spends the most and Pamela Spends the least.
Determine the surface area of the rectangular prism.
Answer:
The answer is 220 cm^2
Step-by-step explanation:
Formula of a rectangular prism: 2 (lw + lh + wh)
2 (lw + lh + wh)
2 (10 x 4 + 10 x 5 + 4 x 5)
2 (40 + 50 + 20)
2 (110)
= 220 cm^2

23. In the figure, A, B, E and C are points on the circle.
AE is the diameter of the circle and AD is the height
of ABC.
Given that CAD = 18°, find BAE.
9514 1404 393
Answer:
18°
Step-by-step explanation:
Angle ACD is the complement of the 18° angle shown, 72°. Arc AB is double that measure, so is 144°. Arc BE is the supplement to that, so is 36°. This is the arc subtended by inscribed angle BAE. That inscribed angle is half the measure of arc BE, so is 36°/2 = 18°.
angle BAE = 18°
