Answers

4 times 3 is 12, so A is 12 mph. 1/3 divided by 4 is 1/12, so B is 1/12 mph. 1/2 divided by 3 is 1/6, so C is 1/6 mph. Finally, if 6 is 2/3 of the mph, you’d divide 6 by 2 to get 3, then multiply by 3 to get 9, so D is 9 mph. So A would be the fastest.

Dustin wants a new pair of shoes that cost $40. His mom pays 75% of the cost and dustin pays 25%. How much do they each pay?

Answers

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.

I'm doing a math test, and I don't understand this question. How many 1/3 inch cubes does it take to fill a box with width 2 2/3 inches, length 3 1/3 inches, and height of 2 1/3 inches?

Answers

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

Can someone helps me eith this , i dont get this. ill give a brainlist to the best answer.​

Answers

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!!

hope this helps!!!

which equation is the point-slope equation of the line that passes through the points (-2,-1) and (7,-4)?

Answers

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)

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
