Step-by-step explanation:

Distribute:

(6)(8x) + (6)(−2y) + −3

48x + −12y + −3

48x − 12y−3

2.) 32

3.) 14

4.) 16

It's the associative property. One way to remember the associative property is that the numbers don't change, but the location of the numbers change.

Answer:

≈ 33°

Step-by-step explanation:

So, first, you can draw a visual. Refer to the image attached below:

Using this info, you can use trigonometric ratios. Recall that:

tangent = opposite side/adjacent side

sine = opposite side/ hypotenuse

cosine = adjacent side/hypotenuse

You can clearly see that you have an opposite side and a given hypotenuse. This means we'll be using sine.

So:

[tex]sinX = \frac{150}{275}[/tex]

However, we're not trying to find sinX, we're trying to find X.

So we would have to use inverse sine, which would then be:

[tex]X = sin-1 (\frac{150}{275} )[/tex]

Put this into your calculator, and:

X ≈ 33.05573115...

french, history, math

Step-by-step explanation:

Reasoning:

If you look at it you can see that french is 11/12 so french is definitely right

so you can eliminate the third question.

Now history is on both of the two answers that could be right.

Answer:

2(x+3)=15     x=6

Step-by-step explanation:

Answer:

Step-by-step explanation:

ccording to the question

3x + 7x = 350

10x =350

X = 35

Therfore

3x = 35 *3 = 105

7x = 35 *7 = 245

Follow me and mark me as a brainliest

Step-by-step explanation:

let ratio be 3xand7x

now,

3x+7x=350

10x=350

x=350/10

x=35

then,

3x=3×35=105

7x=7×35=245

Step-by-step explanation:

Answer:

B. Y=50x+400

Step-by-step explanation:

Answer:

Below.

Step-by-step explanation:

A linear function contains a variable of the first  degree  only - for example f(x) = 2x - 1 or f(z) = 3z.

So y = x + 5 is linear.

Answer:

The expression for the total cost of the visit to dentist is T = 50 + 100n .

Step-by-step explanation:

As given

The price of a visit to the dentist is $50.

If the dentist fills any cavities, an additional charge of $100 per cavity gets added to the bill.

If the dentist n cavities .

Let us assume that the total cost of the visit to dentist be T.

Than the expression becomes

T = 50 + 100n

Therefore the expression for the total cost of the visit to dentist is T = 50 + 100n .

28 + 2 = 30

Answer:

p = 2

Step-by-step explanation:

28 + p = 30

Subtract 28 from both sides

Answer:

C. Point D

Step-by-step explanation:

Distance between two points

Given two points A(x,y) and B(w,z), the distance between them is:

[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]

If both points have the same y-coordinate (y=z), then

[tex]d = |w - x|[/tex]

Point A has coordinates (-2,3). Point D has coordinates (-3,3). The distance between them is

[tex]d = | -2 - (-3) |[/tex]

Thus the correct choice is

C. Point D

Answer:

Area of the shaded region = 1.92 cm²

Step-by-step explanation:

Area of the shaded region = Area of sector OMN - Area of isosceles triangle OMN

Drop a perpendicular OP from vertex O to opposite side MN.

Perpendicular OP will bisect angle MON.

m∠MOP = 25°

By cosine ratio in triangle OPN,

cos(25°) = [tex]\frac{OP}{ON}[/tex]

OP = ON.cos(25°)  

OP = 6cos(25°)

OP = 5.438 cm

By sine ratio of angle PON,

sin(25) = [tex]\frac{PN}{ON}[/tex]

PN = ON.sin(25)

     = 6sin(25°)

     = 2.536 cm

Since, MN = 2(PN)

MN = 5.071 cm

Area of ΔOMN = [tex]\frac{1}{2}(OP)(MN)[/tex]

                         = [tex]\frac{1}{2}(5.438)(5.071)[/tex]

                         = 13.788 cm²

Area of sector OMN = [tex]\frac{\theta}{360}(\pi r^{2})[/tex]

Here 'θ' is the angle subtended by the arc MN at the center.

Area of sector OMN = [tex]\frac{50}{360}(\pi )(6^{2})[/tex]

                                  = 15.708 cm²

Area of the shaded region = 15.708 - 13.788

                                             = 1.92

                                             ≈ 1.92 cm²

Answer:

Area of the shaded region = Area of sector OMN - Area of isosceles triangle OMN

Drop a perpendicular OP from vertex O to opposite side MN.

Perpendicular OP will bisect angle MON.

m∠MOP = 25°

By cosine ratio in triangle OPN,

cos(25°) = \frac{OP}{ON}ONOP

OP = ON.cos(25°)  

OP = 6cos(25°)

OP = 5.438 cm

By sine ratio of angle PON,

sin(25) = \frac{PN}{ON}ONPN

PN = ON.sin(25)

     = 6sin(25°)

     = 2.536 cm

Since, MN = 2(PN)

MN = 5.071 cm

Area of ΔOMN = \frac{1}{2}(OP)(MN)21(OP)(MN)

                         = \frac{1}{2}(5.438)(5.071)21(5.438)(5.071)

                         = 13.788 cm²

Area of sector OMN = \frac{\theta}{360}(\pi r^{2})360θ(πr2)

Here 'θ' is the angle subtended by the arc MN at the center.

Area of sector OMN = \frac{50}{360}(\pi )(6^{2})36050(π)(62)

                                  = 15.708 cm²

Area of the shaded region = 15.708 - 13.788

                                             = 1.92

                                             ≈ 1.92 cm²
