!!! HelpWhat Is The Measurement Of Angle A To The Nearest Degree???

Answers

Answer 1

Answer:

51 = A

Step-by-step explanation:

Using the law of sines

sin 95        sin A

------------- = -----------

9                  7

Using cross products

7 sin 95 = 9 sin A

Divide each side by 9

7/9 sin 95 = sin A

Take the inverse sin of each side

sin ^-1 ( 7/9 sin 95) = A

50.78854367= A

To the nearest degree

51 = A

Answer:

42.5 if rounding 43 for B

Step-by-step explanation:

P is the variable so put 100 under it

Then on the first empty fraction put 17/40

Cross multiply

You will get 40p=17x100

So then you multiply 17 by 100

1700

divided both sides by 40

Get the variable alone

Divide 1700 by 40

get 42.5

a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?

Answers

C(7, 4) = 7! / (4!(7-4)!) = (7 * 6 * 5) / (3 * 2 * 1) = 35

and

C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287

Multiply these two combinations since the faculty members and students are selected independently:

Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045

Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
To determine the number of ways to form the committee with 4 faculty members and 5 students, we need to calculate the combinations of faculty members and students separately and then multiply them together.

For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:

C(7, 4) = 7! / (4!(7 - 4)!) = 35.

So, there are 35 ways to select 4 faculty members from the 7 eligible ones.

For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:

C(13, 5) = 13! / (5!(13 - 5)!) = 1287.

Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.

To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:

35 * 1287 = 44,895.

Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.

what is the nth term of this sequence 7, 9, 11, 13

Answers

Answer:

The nth term of the sequence is

5 + 2n

Step-by-step explanation:

The sequence above is an arithmetic sequence

For an nth term in an arithmetic sequence

A(n) = a + ( n - 1)d

where a is the first term

n is the number of terms

d is the common difference

From the question

a = 7

d = 9 - 7 = 2 or 11 - 9 = 2

So the nth term for the sequence is

A(n) = 7 + ( n - 1)2

= 7 + 2n - 2

A(n) = 5 + 2n

How many quadrants plane have a positive x-value?

Answers

Answer:

2

Step-by-step explanation:Quadrant I and Quadrant IV

Two out of the four Quadrant planes have a positive x- value.

The coordinate axis split the plane into four parts called Quadrants or which can also be called Cartesian quadrants. These divided parts of the plane are numbered I, II, III, and IV.

The first quadrant/ quadrant I which lies on the upper axis on the right side of the plane has two positive quadrants, that is one positive x and one positive y because both of them lie in the positive direction of the axis.

The second quadrant/ quadrant II which appears on the upper right side of the plane has one positive and one negative coordinate that is, one positive y and one negative x because the x coordinate lie in the opposite direction of the sign of the numbers.

In quadrant III which lies in the downward direction and the left side of the plane has two negative coordinates both x and y. both the coordinates go towards the opposite direction of the sign convention.

in the last quadrant/ quadrant IV have a positive x- coordinate and one negative y-coordinate. Because the y coordinate goes against the positive sign convention.

Number 1 is 128.52 Number 2 is 18.56

Step-by-step explanation:

Find the area of the partial circle

Diameter is 6 so the radius is 3

A=\(\pi r^{2}\)

A=2*3.14*\(3^{2}\)                                  \(3^{2}\)=9

A= *3.14*9

A=28.26

Now find the area of the rectangle

A=lw

A=6*12

A= 72

Add both of the answers

Answer is 128.52

Number 1

For triangle

A=1/2bh

A=1/2*3*4

A=1/2*12

A=6

Find the area of the circle

Diameter is twice a radius so the radius would be 2

A=\(\pi r^{2}\)

A=3.14*\(2^{2}\)

A=3.14*4

A=12.56 Add it to 6

A=18.56

Mrs. Jones wants to paint the back wall of her classroom light blue. If the dimensions of the wall is 20 feet by 12 feet, how much paint will she need to paint her classroom wall? Round to the nearest tenth if necessary.

Answers

Answer:

The total area of the back classroom wall is (20ft x 12ft) = 240ft²

The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².

Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.

Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

The answer to the question is 0.6 gallons

The percent of people of the people surveyed were satisfied with the car is  the percent of people of the people would buy that type of car again, so we have:  2015 ÷ 3100 × 100% = 65%

ANSWER: 65%

9(4–5x)+2=7(6x–7) plz help!!

Answer:

Step-by-step explanation:

9(4–5x)+2=7(6x–7)

Distribute

36 -45x +2 = 42x-49

Combine like terms

-45x +38 = 42x-49

Add 45x to each side

-45x +38 +45x = 42x+45x-49

38 = 87x-49

Add 49 to each side

38+49 = 87x-49+49

87 = 87x

Divide by 87

87/87 = 87x/87

1 =x

Answer:

\(x=1\)

Step-by-step explanation:

So we have:

\(9(4-5x)+2=7(6x-7)\)

First, distribute the left:

\(36-45x+2=7(6x-7)\)

Now, distribute the right:

\(36-45x+2=42x-49\)

Add the numbers on the left:

\(38-45x=42x-49\)

Add 49 to both sides. The right cancels:"

\(87-45x=42x\)

Add 45 to both sides:

\(87=87x\)

Divide both sides by 87:

\(x=1\)

And we're done!

Jeff spends $2.52 per gallon of gas and buys 14 gallons. Anna spends $2.16 per gallon of gas and buys 15 gallons.

​How much more does Jeff spend than Anna on gas?

Answers

Step-by-step explanation:

Jeff spends $2.52 per gallon and buys 14 gallons, so his total expenditure is:

Total spent by Jeff = $2.52/gallon * 14 gallons = $35.28

Anna spends $2.16 per gallon and buys 15 gallons, so her total expenditure is:

Total spent by Anna = $2.16/gallon * 15 gallons = $32.40

To find the difference in their expenditures, we subtract Anna's total from Jeff's total:

Difference = Total spent by Jeff - Total spent by Anna

Difference = $35.28 - $32.40 = $2.88

Therefore, Jeff spends $2.88 more than Anna on gas.

To calculate how much more Jeff spends than Anna on gas, we need to find the difference between their total expenses.

Jeff's total expense = $2.52/gallon * 14 gallons = $35.28
Anna's total expense = $2.16/gallon * 15 gallons = $32.40

The difference in their expenses is $35.28 - $32.40 = $2.88.

Therefore, Jeff spends $2.88 more than Anna on gas.
