If the hypotenuse right angle of a triangle is 17 inches long, one of the legs is 15 inches. Find the length of the other leg

Answers

Answer 1

Answer: Use the Pythagorean theorem.
a^2+b^2=c^2

15^2+b^2=17^2

225+b^2=289

Subtract 225 from both sides of the equation and you get:

b^2=64

b=8

We know that for every 5 red bricks there were 2 gray bricks.

The total amount of red bricks and grey bricks in this sample is 7.

5 red bricks + 2 grey bricks = 7 bricks

Now, we divide 175 "total number of bricks used" by 7 "5 red bricks + 2 grey bricks = 7 bricks" and we will get a quotient of 25.

Now we know that 25 bricks is $(1)/(7)$ of the wall. The gray bricks are $(2)/(7)$ so we can multiply 25 by 2 and we will get a product of 50. If 1/7 = 25 grey bricks so 2/7 would be the grey bricks.

175 - 50 = number of red bricks.

Therefore, there were 125 red bricks.

There were 125 bricks knowing that for every 5 bricks there are 2 gray bricks

If 50 is 20% of a value, what is that value?

Answers

the value is 250,
solution:
let the value be 'x'
x×20/100 = 50
20x = 50×100
x = 250

Solve the equation x/4+5/8=3/8

Answers

X/4 +5/8 = 3/8

X/4 = 3/8-5/8

X/4 = (3-5)/8

X/4 = -2/8

Multiply both sides by 4 we get

4x/4 = -8/8

X = -1

c)

−10, 5, −52, 54, ...

d)

3, 6, 12, 24, ...

Answers

Answer: A

Step-by-step explanation: An arithmetic sequence is a pattern in which the same number is repeatedly added or subtracted.

Notice that in the the first sequence shown, we add 4 to reach the next term in the sequence which means this is arithmetic.

The others are not arithmetic because the difference

between the terms does not remain constant.

Tickets to the zoo cost $14 for adults and $10 for children. A group of 12 people went to the zoo, and the tickets cost $140. The system of equations models this situation, where x is the number of adults and y is the number of children.x+y=12
14x+10y=140
How many adults and how many children were in the group?

A.
5 adults and 7 children

B.
6 adults and 6 children

C.
7 adults and 5 children

D.
8 adults and 4 children

Answers

x is the number of adults and y is the number of children.
x + y = 12
14x + 10y = 140
lets multiply the first equation by -10 and then add it to the second equation:
-10x - 10y = -120
14x + 10y = 140
-----------------------
4x + 0 = 20
x = 20/4
x = 5
then substitute in the original equation:
x + y = 12
5 + y = 12
y = 12 - 5
y = 7
therefore there were 5 adults and 7 children
