Answer: the 63rd term is - 176

Step-by-step explanation:

In an arithmetic sequence, consecutive terms differ by a common difference.

The formula for determining the nth term of an arithmetic sequence is expressed as

Tn = a + (n - 1)d

Where

a represents the first term of the sequence.

d represents the common difference.

n represents the number of terms in the sequence.

From the information given,

a = 10

d = 7 - 10 = 4 - 7 = 1 - 4 = - 3

n = 63

We want to determine the value of the 63rd term, T63. Therefore,

T63 = 10 + (63 - 1) × - 3

T63 = 10 - 186 = - 176

11 hours 18 min 36 sec to hours

I'm not really sure about this math but I tried to answer it for you

1)Convert 11 hours to minutes = 660 minutes. 11 hours x 60 mins=660
2)Add the 18 minutes to 660 =678 minutes
3) 678 divided by 60 mins = 11.3 hours, but we still have the 36 seconds remaining so I didn't exactly divide 678 minutes by 60, but I divided 678.36 by 60 which gave me 11.306 hours.

That's it I truly apologise if this is wrong. But if you figure out the right method please show me and others who may have done it this way or another way, so please share. GOOD LUCK.

Statement ∠T and ∠S are complementary ∠S and ∠U are complementary m∠T+m∠S=90 m∠S+m∠U=90 m∠T+m∠S=m∠S+m∠U m∠U=m∠T ∠U≅∠T

Answer:

See Explanation

Step-by-step explanation:

According to the Question,

Given That, ∠T and ∠S are complementary & ∠S and ∠U are complementary

Thus, m∠T + m∠S = 90 ------ Equation 1

& m∠S + m∠U = 90 ------- Equation 2

Now, Subtract Equation 2 From Equation 1, we get

m∠T - m∠U = 0

Thus, m∠T = m∠U

The measure of angle T is equal to angle U.(∠U≅∠T).

Answer: C. 69(0.75)(.0.90)

Step-by-step explanation:

In order to find a discounted price you subtract the discount percentage as a decimal from 1 and multiply the outcome to the original price. For this case, 1-0.25=0.75 and 1-0.1=0.90. So your equation will be 69(0.75)(0.90)
