Side b =1,4

side c =3,4

hope that helps

side c =3,4

hope that helps

Let C be the number of cars and T the number of trucks:

C + T =24

but C = 2T

2T + T = 24

3 T =24 band T =8 so C=16

C + T =24

but C = 2T

2T + T = 24

3 T =24 band T =8 so C=16

QUESTION POSTED AT 17/10/2019 - 09:20 AM

We want to use the Pythagorean theorem to find the missing length of the right triangle described in the word problem.

The Pythagorean Theorem is a^2 + b^2 = c^2, where a and b are the side lengths of the right triangle, and c is the hypotenuse.

If we know the lengths of two sides of a triangle, we can always find the length of the third side using this formula.

We're given the lengths of one of the sides (12) and the hypotenuse (20). We plug these numbers into our equation and then solve for x.

(x represents the how high the ladder reaches)

x^2 + 12^2 = 20^2

x^2 + 144 = 400

x^2 + 144 - 144 + 400 - 144

x^2 = 256

Now, find the square root of each side of the parenthesis.

√x^2 = √256

x = 16.

The answer is 16.

If there's anything you don't understand, I would highly recommend going to the website Khan Academy and watch his videos regarding it, he explains things much better than I ever could.

Hope this helps!!

-1,000-994=6

-1,000 divided by 7=142.86

-142x7=994

-1,000-994=6

QUESTION POSTED AT 17/10/2019 - 09:14 AM

If you have 1000 pencils and you divide by 7 teachers, you would have 142 pencils divided evenly. Then you would take the 142 pencils and multiply by 7 which will give you a total of 994 pencils that went to the teachers in total. So the remaining pencils would be 1000 minus 994 and the total left over will be 6 pencils. I hope this helps.

QUESTION POSTED AT 17/10/2019 - 09:10 AM

It is a case of a **direct variation.**

**Direct variation--**

Two variables x and y are said to be in direct variation if there exist a constant k such that:

i.e. with the increase/decrease in one variable the other variable also increases/decreases.

**Inverse variation--**

Two variables x and y are said to be in inverse variation if there exist a constant k such that:

i.e. with the increase in one variable the other decreases and vice-versa.

Here the independent variable is: Number of gallons used.

and the dependent variable is: Total cost to fill a car gas tank.

As we know that as the number of gallons used increases the total cost also increases and it increases by some constant k.

Since, the cost of per gallons is some fixed.

Part1

there are 360° in a circle (clock), and thus if we check how many degrees in a clock with 60minutes, then it'd be 360/60, or 6° per minute

now, the clock went from 3:35 to 3:55, 20 minutes, how many degree is that? 6*20
