Answer: incorrect,

6r=72

Divide both sides by 6

R=12

Answer:

Brooke's solution is incorrect.

She has to DIVIDE 6 on BOTH sides, not subtract 6 from both sides.

6r = 72

6r/6 = 72/6

r = 12

Answer:

4 inches

Step-by-step explanation:

Jerry built a 2 inch cube to hold his marble collection.

Volume of this cube = 2³ = 8 cubic inches

He wants to build a cube with a volume 8 times larger.

Hence: 8 × 8 in³ = 64 in³

The measurement of each edge is calculated as:

√64 in³ = 4 inches

Answer: See explanation

Step-by-step explanation:

First and foremost, we should not that:

1 yard = 3 feet

We are informed that Wyatt uses 200 feet of rope for each doormat and that he wants to make 25 doormats.

The expression that shows a correct way to find how many yards of rope he needs will be:

= (200 × 25) / 3

= 5000/3

= 1666.67 yards

Answer:

a = 60

Step-by-step explanation:

4 + 6 = 10

6 = a/10

10*6 = 60

6 = 60/4+6

Hope this helps!

Answer:

a=60

Step-by-step explanation:

[tex]6 = \frac{a}{4 + 6} [/tex]

[tex]6 \times 10= \frac{a}{10} \times 10[/tex]

[tex]60 = a \: or \: a = 60[/tex]

Hope this helped you out! no problem.

Answer:

1 hour and 30 minutes

In hours 1.5h, 1 and half an hour

In minutes :

1hour=60 minutes

half an hour=30 minutes

so 60+30=90 minutes

Answer:

10.58 N

Step-by-step explanation:

Let us find component of these forces in x and y direction.

The solution along with diagram can be found in attachment.

We have found resultant in X- direction = 6√3 N

resultant in Y- direction = 2 N

therefore net force resultant force = [tex]\sqrt{(6\sqrt3)^2+2^2}[/tex]

= 10.58 N

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

In order for it to be a function, every input (x values on the left) needs to be paired with only 1 output (y values on the right). Notice that 1 is paired with both 2 and 4.  This means it is not a function, but it is paired with two different values.

Answer:

$601.24

Step-by-step explanation:

623.45 - 50 - 3 + 75 - 7.29 - 36.92 = 601.24

Answer:

451.24

Step-by-step explanation:

first of all, you would subtract 53 from 623.45 then you would subtract 75 from the difference next you would subtract 7.29 from that difference lastly you would subtract 36.92 from that difference to find your answer  

Answer:

12x + 3 + 7x - 13 = 180

Step-by-step explanation:

Q and R are Same Side Interior Angles

If you add any two same side interior angles for a trapezoid, they will equal 180 degrees.

Therefore, 12x + 3 + 7x - 13 = 180 degrees

Answer:

12x + 3 + 7x - 13 = 180

Step-by-step explanation:

The top and bottom sides of the trapezoid are parallel, but the sides are not. This means that the two angles that we are trying to find cannot be equal. In this case, this can only mean that both sides can be combined to complete a 180 degree angle. This can also be determined since they are supplementary angles, or angles that are adjacent to the opposite side of another base.

Answer:

1) x = 20. 8

2) x = 42.3

3) x = 13.0

4) x = 42.1

Step-by-step explanation:

1) Use Sine

(Sine = [tex]\frac{opposite}{hypothenuse}[/tex]) Sine 53 = [tex]\frac{x}{26}[/tex]

(sine of 53 is 0.80) 0.80 = [tex]\frac{x}{26}[/tex]

(multiply 26 on both sides) 0.80 x 26 = [tex]\frac{x}{26}[/tex] x 26

(solve) 20.8 = x

2) Use Tan

(Tan = [tex]\frac{opposite}{adjacent}[/tex]) Tan 78 = [tex]\frac{x}{9}[/tex]

(tan of 78 is 4.70) 4.70 =  [tex]\frac{x}{9}[/tex]

(multiply 9 on both sides) 4.70 x 9 =  [tex]\frac{x}{9}[/tex] x 9

(solve) 42.3 = x

3) Use Cosine

(Cosine = [tex]\frac{adjacent} {hypothenuse}[/tex]) Cos 22 = [tex]\frac{14}{x}[/tex]

(cos of 22 is 0.93) 0.93 = [tex]\frac{14}{x}[/tex]

(multiply 14 on both sides) 0.93 x 14 = [tex]\frac{14}{x}[/tex] x 14

(solve) 13.02 = x

(round to the nearest tenth) 13.02 = 13.0

4) Use tan

(Tan = [tex]\frac{opposite}{adjacent}[/tex]) Tan 39 = [tex]\frac{52}{x}[/tex]

(tan of 39 is 0.809) 0.809 = [tex]\frac{52}{x}[/tex]

(multiply 52 on both sides) 0.809 x 52 = [tex]\frac{52}{x}[/tex] x 52

(solve) 42.068 = x

(round to the nearest tenth) 42.068 = 42.1

[tex]\boxed{imperturbability}[/tex]

Answer:

x = 25

Step-by-step explanation:

75 = (4x - 25)

Since there are no numbers outside of the parentheses, we can remove them.

75 = 4x - 25

Now we can see that we can add 25 to both sides.

100 = 4x

Divide both sides by 4 to isolate x.

25 = x

Check by plugging in the value into the original equation.

75 = 4(25) - 25

75 = 100 - 25

75 = 75

Your answer is correct.

Hope this helps!

Answer:

D. y - 3 = - 12 ( x - 5)

Step-by-step explanation:

Given

Slope (m) = - 12

Point = ( 5 , 3 ) = ( x1 , y1)

Now

Writing in point-slope equation we get

y - y1 = m( x - x1)

y - 3 = - 12 ( x - 5 )

Hope it will help :)❤

Answer:

20/n+10 = 10/n+20 n

multiply both side n,

n (20/n+10) = n(10/n+20 n)

20+10n = 10+20n^2

20+10n -20 = 10+20n^2 -20

10n  = 20n^2 -10

10n  - 10n  = 20n^2 -10 -10n

0 = = 20n^2 -10 -10n

20n^2 -10 -10n = 0

n = 1 or n = -0.5

Answer:

s = 1

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5 , then

sum = 180° × 3 = 540°

sum the interior angles and equate to 540

39s + 129 + 79 + 145 + 148 = 540 , that is

39s + 501 = 540 ( subtract 501 from both sides )

39s = 39 ( divide both sides by 39 )

s = 1
