Answer: [tex]882\ in.^2[/tex]

Step-by-step explanation:

Given

The surface area of the cube is [tex]294\ in.^2[/tex]

Surface area is increased by a scale factor of 3

Enlarged surface area is

[tex]\Rightarrow 294\times 3=882\ in.^2[/tex]

Answer:

1. Adjacent and formed a linear pair

2. Adjacent and formed a linear pair

3. Adjacent

4. Not adjacent

Step-by-step explanation:

In essence, adjacent angles are two angles side by side. Two adjacent angles can form a linear pair when they are created by two lines intersecting. So, in broad terms, they are adjacent on a flat plane (or a straight line), and together they make a 180° angle.

Answer:

I dont know, i'm just doing this to get points. lol

Answer:

x = 28

Step-by-step explanation:

AB= AC

∠B = ∠C    {Angles opposite to equal sides are equal}

∠A + ∠B + ∠C = 180    {angle sum property}

3x + x + 20 + x + 20 = 180 {Combine like terms}

3x +x +x + 20 + 20 = 180

          5x + 40 = 180          {subtract 40 from both sides}

                   5x = 180 - 40

                  5x = 140      {divide both sides by 5}

                    x = 140/5

x = 28

Answer:

A = 60 and B = 30  

Now, A + B = 60 + 30 = 90  

Also, A – B = 60 – 30 = 30  

sin (A + B) = sin 90 = 1  

sin A cos B + cos A sin B = sin 60 cos 30 + cos 60 sin 30

Step-by-step explanation:

Given

Maria goal's is to Jog 17.4 miles

She runs 2.75 miles each day for 7 days

Total distance covered by her in 7 days

[tex]\Rightarrow 2.75\times 7=19.25\ \text{miles}[/tex]

So, she covers more than what she had planned.

Therefore, she is successful in her plan.

The surface area of the composite solid is 165 [tex]feet^2[/tex].

We possess

4 triangles, each measuring 6 feet in height and 5 feet in base

4 rectangles, each measuring 5 feet long and 4 feet wide

1 square has side a = 5 feet.

The formula for a triangle's area is:

[tex]A_T=\frac{1}{2} bh[/tex]

Substitute:

[tex]A_T=\frac{1}{2} 5*6\\A_T=\frac{1}{2} 30\\A_T=15 ft^2[/tex]

Formula for calculating a rectangle's area:

[tex]A_R=lw[/tex]

Substitute:

[tex]A_R=5*4\\A_R=20 ft^2[/tex]

The formula for a square's area is as follows:

[tex]A_s=a^2[/tex]

Substitute:

[tex]A=s=5^2\\A_s=25 ft^2[/tex]

The composite solid's surface area is:

[tex]SA=4A_T+4A_R+A_s[/tex]

Substitute:

[tex]SA=4*15+4*20+25\\SA= 60+80+25\\SA=165 ft^2[/tex]

The composite solid has a surface area of 165 [tex]feet^2[/tex].

Is the answer when y=9

Answer:

Step-by-step explanation:

First do 4 -2 to get 2. Then do 30-15 to get 15. It’s 2:15.

You can also do this on a calculator by doing 4.15-2.30. You get 1.85

Remember that time is only up to 60 So you have to subtract 15 from 85 to get 60. So it’s 2 hours and 15 minutes. Hope this helps!

13 quarts

Step-by-step explanation:

Remember this:

1 mug = 16 oz

1 quart = 32 oz

Find total quarts of coffee.

Setup proportion and solve for x ounces:

[tex]\frac{1 mug}{16 oz} =\frac{26 mugs}{xoz}\\\\x oz=16(26)=416 oz[/tex]

Setup another proportion to solve for x quarts and also use the 416 oz.

[tex]\frac{32oz}{1 qt} =\frac{416oz}{xqt} \\x=\frac{416}{32} = 13 qt[/tex]

Commutative property

Step-by-step explanation:

Answer:

Answer is B: (-sqrt(3/2 , -1/2)

Step-by-step explanation:

First convert radians to degrees

theta = (7pi/6)*(180/pi)

=210 degrees

Cos(210 degrees)= -sqrt3/2

Thats the x coordinate

sin(210 degrees)= -1/2

thats the y coordinate

Answer:

The corresponding point on the unit circle for the radian measure is [tex](\frac{\sqrt{3} }{2},\frac{1}{2})[/tex]

Step-by-step explanation:

What is unit circle?

A unit circle is typically drawn around the origin (0,0) of a X,Y axes with a radius of 1.

What is radian measure?

One radian is the measure of a central angle that intercepts an arc s equal in length to the radius r of the circle.

The radian measure is,

α=[tex]\frac{7\pi }{8}[/tex]

Changing to degree measure,

[tex]\frac{7\pi }{6} *\frac{180}{\pi } \\=210^{o}[/tex]

The measure on the unit circle is,

(cos [tex]\alpha[/tex] , sin [tex]\alpha[/tex])=(cos 210 , sin 210)

                    =[tex](\frac{\sqrt{3} }{2},\frac{1}{2})[/tex]
