I don’t know this one question

Answers

Answer 1

Answer:

v = 13

Step-by-step explanation:

because they are supplementary angles they add up to 180

add them

and put them equal to 180

9v + 3 + 60 = 180

combine like terms

9v + 63 = 180

now subtract 63 to both sides

9v = 117

divide 9 to both sides

v = 13

that is your answer

The student activities office has four students who work part-time on a work-study program. Three of the students work
17 hours per week, 19 hours per week, and 16 hours per week. The office policy is that the average number of hours
students work per week in the student activities office is less than 17.5 hours. What is the restriction for the number of
hours that the fourth student can work?

Answers

Answer:

less than 18 hours

Step-by-step explanation:

You want the restriction on the fourth value such that the average of it and 17, 19, and 16 will be less than 17.5.

Average value

The average of a set of numbers is their sum, divided by the number of numbers. The average of the four students' hours will be ...

(17 +19 +16 +h)/4 < 17.5 . . . . . . restriction on average hours

Solution

Multiplying by 4 gives ...

52 +h < 70

h < 18 . . . . . . . . subtract 52

The fourth student can work less than 18 hours.

Suppose you had d dollars in your bank account. You spent $14 but have at least $48 left. How much money did you have initially? Write and solve an inequality that represents this situation.

Answers

The inequality that represents this situation is d - 14 >= 48 and the solution is d >= 62

How to write and solve an inequality that represents this situation.

The given parameters are:

Initial amount = d

Spent = 14

Amount left = at least 48

The above means that

d - 14 = at least 48

at least 48 means greater than or equal to 48

So, we have

d - 14 >= 48

Add 14 to both sides

d >= 62

Hence, the inequality that represents this situation is d - 14 >= 48 and the solution is d >= 62

Answers

Based on the temperature readings, the average recorded temperature in the 20 days was 10.15°

What was the average temperature?

The average temperature can be found by adding all the temperatures and then dividing by the number of temperatures taken which is 20.

The average is therefore:

= 24° + (−10°) + 9° + 18° + 23° + 27° + 8° + 17° + 3° + 7° + ( −2°) + (−6°) + 2° + (−9°) + (−8°) + 21° + 25° + 15° + 10° + 29°) / 20

= 203 / 20

= 10.15°

The amount of water a bag of salt can treat is 47, 250 cubic feet

How to determine the volume

The formula for volume of a rectangle is expressed as;

Volume = length × width × height

From the information given, we have the following parameters;

Length = 25 yardsWidth = 14 yardsHeight = 5 yards

Substitute the values into the formula

Volume = 25 × 14 × 5

Find the product

Volume = 1750 cubic yards

Covertoing cubic yard to cubic feet

I cubic yard = 27 cubic foot

1750 yards = x

x = 27 × 1750

x = 47, 250 cubic feet

Thus, the amount of water a bag of salt can treat is 47, 250 cubic feet

The graph of the function f(x) = –(x + 6)(x + 2) is shown below.

On a coordinate plane, a parabola opens down. It goes through (negative 6, 0), has a vertex at (negative 4, 4), and goes through (negative 2, 0).

Which statement about the function is true?

The function is increasing for all real values of x where
x < –4.
The function is increasing for all real values of x where
–6 < x < –2.
The function is decreasing for all real values of x where
x < –6 and where x > –2.
The function is decreasing for all real values of x where
x < –4.

Answers

The correct statement about the given function is: The function is increasing for all real values of x where x < –4.

In this question, we have been given the graph of the function

f(x) = -(x + 6)(x + 2)

According to description of the graph of given function f(x), the graph of function is a parabola and on a coordinate plane, a parabola opens down.

Also, the parabola goes through (-6, 0), has a vertex at (-4, 4), and goes through (-2, 0).

We need to find to the correct statement about the function.

f(x) = -(x + 6)(x + 2)

The function is increasing until it reaches the vertex x = -4.

The function will decrease after the vertex, so after x = -4 function decreases.

increasing: -∞ < x < -4

decreasing : -4 < x < ∞

Therefore, the correct statement about the given function is: The function is increasing for all real values of x where x < –4.

What is the 19th term of the sequence:

gn=gn−1⋅(−12) if g17=162
the sixth term is ______

Answers

This is an arithmetic sequence

The nth term of an arithmetic sequence is Tn = a + (n-1)d

a is the first term.

n is the number of terms

d is the common difference

Given that 19th term of the sequence is:

gn=gn−1⋅(−12) if g17=162

Suppose a=12

Then,

The 17th term g17=a+(n-1)d

= 12+(17-1)d

'n' means number of terms

12+(17-1)d=162 because g17=162

12+16d=162

16d=162-12

Subtract the values,

We can write,

16d=150

d=150/16

Divide the values,

We can write,

d=25

To get the sixth term g6

g6=12+(6-1)d

=12+5d

Replace with d value in above equation,

Then, g6=12+5(25)

g6=12+125

g6=137

So, the sixth term is g6=137.

Your answer should be 90 degrees for angle one. For angle two, 58 and angle three 32.

Step-by-step explanation:

This is because they are supplementary angles! I hope this helps. Xx

Answer: ∠1 = 90°

Step-by-step explanation:

∠1 = ∠4

∠2 = ∠5

∠3 = ∠6

reason = vertically opposite angle

∠1 = 90°

∠2 = 58°

∠3 = 32°

checking :

total angles = 360°

360° = ∠1 + ∠2 + ∠3 + ∠4 + ∠5 + ∠6

360° = 90° + 58° + 32° + 90° + 58° + 32°

360° = 360°
