I'll do the first problem to get you started.

Triangle SRT is a right triangle with the 90 degree angle located at angle RST. This is because segment SR is an altitude of the triangle. Altitudes of a triangle go from a vertex to the opposite side, and they are perpendicular to the opposite side.

The acute angles of right triangle SRT add up to 90 degrees. They are complementary angles.

(angle SRT) + (angle STR) = 90

(4x-8) + (6x+13) = 90 .... substitution

10x + 5 = 90

10x + 5 - 5 = 90 - 5 .... subtract 5 from both sides

10x = 85

10x/10 = 85/10 .... divide both sides by 10

x = 8.5

Therefore the answer is choice A) x = 8.5

How many multiples of 4 are natural<br> numbers less than or equal to 10?
zheka24 [161]

Answer:

2, there'd be more, but natural numbers are like, whole numbers, integers basically except they're like non-negative integers. Enough ranting. So 4 and 8 would be the numbers because they are mulitplied by 4,1, and 2.

Since 4 cant go into 10 completely without a decimal, there'd only be 2 multiples.

Confusing explanation, but i think my answer is correct. (or is it, dun dun dun!)

Have a good day~

If the 5 of them weigh 1/4 of a ton
then 1 of them weigh x

5/1 = 1/4//x Do you see what happens? Just by writing down the givens you get a proportion. It will work better for you if you change the 1/4 to 0.25

5/1 = 0.25/x Now it looks like an ordinary proportion. Cross multiply
5x = 0.25*1 divide by 5
x = 0.25/5
x = 0.05 tons. We better change this to pounds.

1 ton = 2000 pounds
0.05 ton = x

1/0.05 = 2000/x Cross multiply
x = 2000 * 0.05
x = 100 pounds.
