Answer:

C

Step-by-step explanation:

x-intercept occurs when y=0.

2x -3y= 8

When y=0,

2x -3(0)= 8

2x= 8

x= 8 ÷2

x= 4

Thus the coordinates is (4,0).

Answer:

BC = 24

Step-by-step explanation:

Since angle B is equal to angle C

AC = AB

3x-15 = x+33

Subtract x from each side

3x-15 -x=x+33-x

2x-15 = 33

Add 15 to each side

2x-15+15 = 33+15

2x = 48

Divide by 2

2x/2 = 48/2

x = 24

We want BC = x

BC = 24

Step-by-step explanation:

The opposite side is the side of the triangle facing the given angle. The adjacent side is the side that the given angle and the right angle lies on. The hypotenuse side is the side facing the right angle. (The hypotenuse side usually looks like a slanted line. Do note that this is not true if your adjacent and hypotenuse side is not horizontal and vertical respectively on the plane of your paper.)

I'll explain a bit more below using the some of the questions.

Q1) The given angle here is 27°.

X is facing the given angle hence it is the opposite side.

The side that is 10 units long is the adjacent side as 27° and the right angle sits on it.

tanθ= opp/adj

tan27°= x/ 10

x= 10(tan 27°)

x= 5.1 units (nearest tenth)

Q3) x is the adjacent side, while the side that is 7 units long is the hypotenuse side.

cosθ= adj/hyp

cos39°= x/7

x= 7(cos39°)

x= 5.4 units (nearest tenth)

Q4) x is the hypotenuse and the opposite side is 8 units long.

sinθ= opp/hyp

sin46°= 8/x

x(sin46°)= 8

x= 8/ sin46°

x= 11.1 units (nearest tenth)

Q5) x is facing the given angle, hence it is the opposite side. The adjacent side is given here, which is 6 units long.

tanθ= opp/adj

tan23°= x/6

x= 6(tan 23°)

x= 2.5 units (nearest tenth)

Feel free to ask if you still do not understand any concepts :)

sinθ= opp/hyp

cosθ= adj/hyp

tanθ= opp/adj

Answer:

17.8

Step-by-step explanation:

First:

put the equation together

(2x+3) * (x+2)=91

Secondly:

condense

parenthisis can be dropped and normal problem solving can be used.

5x+2=91

subtract 2 from either side of the =

this will give you 5x=89

next divide 5 from each side because it is multiplying the x

x=17.8

Answer: A; The prepaid phone plan will have a steeper line and lower y-intercept.

"The prepaid phone plan, whose cost is $0.20 per minute, will means the usage increases as time increases means that this will have a steeper line and lower y-intercept since it has no monthly fee, Contracted phone plan, whose fee is still $0.02 would have a less steep line and a higher y-intercept because the plan requires monthly fee of $50."

Hope this helps

A. The prepaid phone plan will have a steeper line and lower y-intercept.

Grace is comparing plans of cell phone.

A prepaid phone plan costs $0.20 per minute and has no monthly fee.

A contracted phone plan costs $50 per month and $0.20 per minute

Time increases as usage of the prepaid phone increases, which cost $0.20 per minute. So, the line will be steeper. There is no monthly plan in prepaid phone, so lower y-intercept seen in the graph.

The cost of contracted phone is $0.20 per minute, so the line is less steeper. Again, contracted phone has monthly plan of $50 per month, so the y intercept will be higher.

Can not represent as a function. since some output have more than one input

The sample space S of a random experiment is defined as the set of all possible outcomes of an experiment. In a random experiment, the outcomes, also known as sample points, are mutually

No, because various numbers of students complete different sizes of homework, the number of students who finish their homework cannot be expressed as a function of the size of the assignment.

Khaled, for instance, was assigned a size 8 assignment twice, and on each occasion, a different amount of pupils finished it (24 and 21). There should only be one output for each input in a function, yet in this situation, some inputs have more than one output.

Answer:

∠F=56.5⁰

Step-by-step explanation:

It forms a right angled triangle.

The base of the triangle is given as 7.7 feet

The perpendicular of the triangle is given as 5.1 feet.

Find ∠E where

tan∠E=perpendicular/base

tan∠E=7.7/5.1

∠E=33.518

Find ∠F by substracting ∠G and ∠E from 180,

∠F=180-90-33.518

∠F=56.482

Round off to nearest tenth

∠F=56.5

Answer & Step-by-step explanation:

The equation for slope-intercept form is y=mx+b

In order to solve this problem, we can just solve the equation to find y.

y - 6 = 5(x - 2)

Distribute 5 to (x - 2)

y - 6 = 5x - 10

Add 6 to both sides of the equation.

y = 5x - 4

So, the slope of the line is 5.

The required slope of the line m = 5

What is the slope of the line represented by the equation y-6 = 5(x - 2)

line, is curve showing the shortest distance between 2 points.

Given line y-6 = 5(x - 2)
standard equation of line = [tex]y-y_1=m(x-x_1)[/tex]
compare the standard equation of line with standard equation
m=5

Thus, The required slope of the line m = 5

area of rectangle = 7 × 11 = 77 cm²

area of circle = πr² = π × 2² = 4π cm²

Thus

area of shaded region = 77 - 4π ≈ 64.43 cm² ( to nearest hundredth )

Answer:

Volume of the box = [tex]2244inches^{3}[/tex]

Step-by-step explanation:

Given

Number of reams in one stack = 4

Number of stacks in the box = 3

Dimensions of a ream = 8.5 inches, 11 inches and 2 inches respectively

To find

Volume of one ream = Length × Breadth × Height

                                   = 8.5 × 11 × 2

                                   = [tex]187 in^{3}[/tex]

Volume of all the four reams in one stack = 187 × 4

                                                                      = [tex]748in^{3}[/tex]

Volume of all the three stacks in the box = 748 × 3

                                                                    = [tex]2244in^{3}[/tex]

∴ Volume of the box = [tex]2244inches^{3}[/tex]

Answer:

C. (8, 4)

Step-by-step explanation:

I graphed it

Answer:

(8,4)

Step-by-step explanation:

4x + 7y= 60

- 4x + 7y= -4

Add the two equations together to eliminate x

4x + 7y= 60

- 4x + 7y= -4

-----------------------

  14y = 56

Divide each side by 14

14y/14 = 56/14

y = 4

Now find x

4x +7y = 60

4x +7(4) = 60

4x+28 = 60

Subtract 28 from each side

4x = 60-28

4x= 32

Divide by 4

4x/4 = 32/4

x =8

Step-by-step explanation:

inner region

A=πr^2

A=π*6^2

A=π*36cm^2

A=113.09cm^2

shaded region(outer)

A=πr^2

A=π*9^2

A=π*81cm^2

A=254.46cm^2

Area of shaded region=254.46cm^2-113.09cm^2

=141.37cm^2

Mark brianliest if my answer suit your question

Radius of the outer circle = 9cm

Area of a circle = πr²

= π×9×9

= 254.34cm²

Radius of the inner circle = 6cm

Area of a circle = πr²

= π×6×6

=113.04cm²

Therefore, area of the shaded region = 254.34-113.04

=141.30cm²
