It would be 80 gallons of water that the dishwasher will use to wash 10 loads of dishes. To figure this out you would need to divide 32 by 4 which would equal 8. You would do this to figure out how many gallons of water a dishwasher needs to wash 1 load of dishes. Then you would multiply 8 times 10 which would equal 80. Hope this helps you!

A group of friends wants to go to the amusement
Zepler [3.9K]

Answer:

The maximum amount of people that can go to the amusement park is 15.

Step-by-step explanation:

First you create an equation to represent the question

8.75+25.75x≤420

You put the less than or equal to sign because 420 is the maximum amount of money.

Now you just solve the equation.

25.75x≤420-8.75

25.75x≤411.25

x≤411.25/25.75

x≤15.9708738

Then you have to round down because you cant have .9 of a person.

So x≤15

Then, Check your solution

8.75+(25.75 x 15)≤420

8.75+386.25≤420

395≤420

That is true. But to make sure that is the maximum add another 25.75

395+25.75≤420

420.75≤420

This is equation is false so, our answer is correct.

The maximum amount of people that can go to the amusement park is 15.

Which point on the x-axis lies on the line that passes through point P and is perpendicular to line MN?
rodikova [14]

1. Points M and N have coordinates (-4,0) and (4,2), respectively.

Then vector \overrightarrow{MN}=(4-(-4),2-0)=(8,2) is perpendicular to the neede line.

2. Write the equation of line that passes through the point P(2,-4) and is perpendicular to vector  \overrightarrow{MN}=(8,2):

8(x-2)+2(y+4)=0,\\8x-16+2y+8=0,\\8x+2y-8=0,\\4x+y-4=0.

3. Find the point on x-axis, that lies on the perpendicular line.

When y=0, then 4x-4=0, x=1 and point (1,0) lies on perpendicular line.

Answer: correct choice is C.

A card is drawn from a deck of 52 cards, what is the probability that it is a number 2?
Rudiy27
The answer in fraction form is exactly 1/13
The approximate answer in decimal form is 0.076923

To get this answer, note how there are four cards that have "2" on them. This is out of 52 total. So we divide the values: 4/52 = 1/13. Don't forget to fully reduce as much as possible. 

To go from 1/13 to 0.076923, you would use a calculator or long division
