Answer:

B (for question 7)

Step-by-step explanation:

To find the slope, we use the equation [tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex].

m = (-4+1)/(7+2) = -3/9 = -1/3

Since B is the only option that would give a slope of -1/3, B must be the answer.

(you can use this same method for question 8)

Answer:

1, 3, 7, 21

Step-by-step explanation:

21/1 = 21

21/3 = 7

21/7 = 3

21/21 = 1

Answer:

Factors of 21 are shown below.

Step-by-step explanation:

Dividing

21 ÷ 3 = 7

21 ÷ 1 = 21

21 ÷ 7 = 3

21 ÷ 21 = 1

Multiplying

3 x 7 = 21

21 x 1 = 21

7 x 3 = 21

1 x 21 = 21

Given:

Dustin wants a new pair of shoes that cost $40.

His mom pays 75% of the cost and dustin pays 25%.

To find:

How much do they each pay?

Solution:

We have,

Total cost of shoes = $40

His mom pays 75% of the cost.

[tex]\text{Mom pays}=\dfrac{75}{100}\times 40[/tex]

[tex]\text{Mom pays}=\dfrac{3}{4}\times 40[/tex]

[tex]\text{Mom pays}=30[/tex]

Dustin pays 25% of the cost.

[tex]\text{Dustin pays}=\dfrac{25}{100}\times 40[/tex]

[tex]\text{Dustin pays}=\dfrac{1}{4}\times 40[/tex]

[tex]\text{Mom pays}=10[/tex]

Therefore, Dustin pays $10 and his mom pays $30.

Answer:

Area = 144 inches2

or

Area = 1 feet2

Steps:

1.5 feet = 18 inches

Area =  l × w

=  8 × 18

=  144 inches2

or

8 inches = 0.66666666666667 feet

Area =  l × w

=  0.66666666666667 × 1.5

=  1 feet2

Answer:

(2,10)

Step-by-step explanation:

so we can substitute the y = 5x into y = 6x - 2

so we would have

5x = 6x - 2

subtract 6x from both sides

-x = -2

remove the negative signs since they're on both sides

x = 2

so now we can substitute x = 2 into y = 5x

so we would get

y = 5(2)

y = 10

So the point will be (2,10)

Check:

y = 6x - 2

10 = 6(2) - 2

10 = 12 - 12

10 = 10

y = 5x

10 = 5(2)

10 = 10

Answer:

(2, 10)

Step-by-step explanation:

substitute the given value of y into the equation (y=5x)

6x-2 =5x

solve for x

"add" the -2 to the other side to leave the x by itself on one side

6x=5x+2

"subtract" the 5x to the other side to combine the x's

6x-5x=2

collect like terms

x=2

so you now have your x to solve  for y

substitute the x into the equation (y=5x)

y=5(2)

simple

y=10

and there you have it!!

Step-by-step explanation:

The triangle is right angled meaning that one of the angles is 90⁰.

90+30+(9x-3)=180 (Angle sum property of a triangle)

120+9x-3=180

9x-3=180-120

9x-3=60

9x=60+3

x=63/9

x=7

The angle will be (9×7)-3=60⁰

Answer: 62

Step-by-step explanation:

First and foremost, we have to calculate the volume of the box which will be:

= 2 2/3 × 3 1/3 × 2 1/3

= 8/3 × 10/3 × 7/3

= 560/27

= 20 20/27

The number of 1/3 inch cubes needed to fill the box will then be:

= 20 20/27 ÷ 1/3

= 560/27 ÷ 1/3

= 560/27 × 3

= 560/9

= 62 2/9

Therefore, 62 boxes can be filled

Answer:

1160 cm^2

Step-by-step explanation:

Surface area=2(lw)+2(hl)+2(hw)

So, surface area=2(15x20)+2(8x15)+2(8x20)

=2(300)+2(120)+2(160)

=600+240+320

surface area=1160 cm^2.

The surface area of the cuboid is 1160 cm²

What is the surface area of cuboid?

The total surface area of the cuboid is given by the formula

Surface Area = 2 ( LH + LW + HW )

where ,

Length of the cuboid = L

Width of the cuboid = W

Height of the cuboid = H

Given data ,

Length of the cuboid L = 15 cm

Width of the cuboid W = 20 cm

Height of the cuboid H = 8 cm

Surface Area of the cuboid = 2 ( LH + LW + HW )

Substituting the values of L , H and W in the equation , we get

Surface Area of the cuboid = 2 ( ( 15 x 8 ) + ( 15 x 20 ) + ( 20 x 8 ) )

So ,

Total surface area of the cuboid = 2 ( 120 + 300 + 160 ) cm²

                                                      = 2 ( 580 ) cm²

                                                      = 1160 cm²

Hence , the Total surface area of the cuboid is 1160 cm²

Answer:

D. x = 18 cm , y = 9

Step-by-step explanation:

With reference angle 60

perpendicular (p) = 9[tex]\sqrt{3}[/tex]

base(b)= y

hypotenuse (h) = x

Then

sin 60 = p/h

[tex]\frac{\sqrt{3} }{2} = \frac{9\sqrt{3} }{x}[/tex]

x = 18

Now

cos 60 = b/h

1/2 = y/18

y = 9
