Can someone help me understand ratios?Like equivalent ratios? I don't remember learning that when I was in school.It's so I can explain it to my 11 year old son for his homework.
Answers
Answer 1
Answer:
Equal ratios are those that are equal to each other.
Example:-
4/2 = 8/4
Also, ratios compare to values, and there are 3 ways to write a ratio.
4/2 and 4:2 and 4 to 2
Answer 2
Answer:
You can write endless equivalent ratios. How? What you do in the numerator, you do in the denominator.
5m+6+m-18=60That's a linear equation in 'm '. There's only one number that 'm' can be that makes the equation true. The assignment is usually to find out what that number is.
Before we get carried away and confuse ourselves, let's do some work on the left side, and try to make it simpler.
Do you see that ' 5m ' and that ' +m ' ? We can combine them, and write ' 6m '.
Do you see that ' +6 ' and that ' -18 ' ? We can combine those, and write ' -12 '.
Now the equation is much simpler:
6m - 12 = 60
Add 12 to each side:
6m = 72
Divide each side by 6 :
m = 12
5m + 6m - 18 = 60 combine like terms 11m - 18 = 60 subtract from both sides -18 -18
11m = 78 divide 11
m = 7. 0909..... round to.. = 7.1

1. The legs of a right triangle measure 24 feet and 45 feet. what is the length of the hypotenuse?A. 51ft B.69ft C.38.07ft D.8.31ft
2. Which of these cannot represent the lengths of the sides of a right triangle? A.3 ft,4 ft,5 ft B.6 in,8 in,10 in C.16 cm,63 cm,65 cm D.8 m,9 m,10 m
Answers
1.
so remember a^2+b^2=c^2
a and b are the legs c=hypotonuse so a=24 b=45 subsitute 24^2+45^2=c^2 576+2025=c^2 2601=c^2 square root both sides 51=c
the answer is A. 51 ft
2. just subsitute and solve for ones that are not equal (hypotonuse is greater than either legs) A. 3^2+4^2=5^2 9+16=25 25=25 correrct
B. 6,8,10 this is a multiplule of the 3,4,5 previoius so this works as well
C.16^2+63^2+65^2 256+3969=4225 4225=4225 correct
D. 8^2+9^2=10^2 64+81=100 145=100 false
the answer is D
ANSWERS: 1. A, 51 ft 2. D, 8,9,10
The answer is A).51 ft To solve the problem use the Pythagorean Theorem. There are 3 parts to the Pythagorean Theorem. A (squared)+ B (squared) = C(squared). To "square" a number mutiply to itself. A=24 B=45, C is the Hypotenuse, you want to find out C. A is 24, a leg. B is 45, a leg. A squared is 24*24, 576 feet. B squared is 45*45, 2025 feet. To find C (the hypotenuse), add 576+2025 which is 2601 feet. The answer is **2601 feet**. Sometimes they will only give you 1 leg and the hypotenuse and want you to find the 2nd leg answer. An example is if they asked " a right triangle has a 24 ft leg and hypotenuse is 2,601 ft. What is the length of the other leg? Still use Pythagorean Theorem. A is 24 ft, you are looking for B, you know that C is 2601 ft. So it is (24*24) +X squared=2601 ft. Then 2601-576. The answer is 2025, press square root button and it is 45 ft
