m∠R=140 and m∠S=100. Find the m∠T. The diagram is not on the scale.

Answers

Answer:

m<T = 20°

Step-by-step explanation:

m<R = 140°

m<S = 100°

The figure given is a kite. The angles formed where two unequal sides meet are always congruent to each other. This means:

m<S = m<U = 100°

Sum of all interior angles of a quadrilateral = 360°

Therefore:

m<T = 360° - (m<S + m<U + m<R)

m<T = 360° - (100° + 100° + 140°) (substitution)

m<T = 20°

Answer:

2.3×10/10=23/10=2 3/10 is mixed number

so basically, decimal points are tenths, hundredths, thousandths, etc. In this number, we have a digit in the ones place, and the tenths place. Decimals are based of 10. So, 0.3 would equal to 3/10, be it is 3 of 0.1 or 1/10. We cannot simply 3/10 because they only have a common factor of 1. So the final answer would be 2 3/10.

Of those who like to fish, what percent are ages 13-18?

Answers

Answer:

B.) 42.9

Step-by-step explanation:

The percent that we are trying to find out is 12/28

I know this because if you add the 12 and 16 which is the total amount of people given then it leaves us with an amount of 28 people. Since we are trying to find the percent of the number of people who like fish we have to divide the total by 12 (the number of people who like fish)

Anyways 12 divided by 28 = 42.857etc.

If we simplify this then that gives us our answer of B.) 42.9

8(__+__)=8m+8n Please help, ​

Answers

It’s 8 (m+n) = 8m + 8n

Answer: m and n

8(m+n)= 8m + 8n

3n + 8 = 53
I don’t understand how to find the n

Answers

Answer:

n=15

Step-by-step explanation:

subtract 8 from both sides to get 3n=45

divide both sides by 3 to solve for n to get n=15

Answer:

n = 15

Step-by-step explanation:

3n + 8 = 53

the first step we are going to do is combine the like terms by moving the constant (8) to the right and subtracting

3n = 45

next step, we are going to isolate the n by dividing by 3 on both sides of the equation

3n divided by 3 is just n and 45 divided by 3 is 15, so we have our answer
