1 answer:
liberstina [14]3 years ago
5 0

Answer:

a =  5.2 units, c =  11.1 units to the nearest tenth.

m < A = 27 degrees.

Step-by-step explanation:

c / sin 100 = 9 / sin 53

c =  9 * sin 100 / sin 53

c = 11.098.

m <  A = 180 - 153 = 27 degrees.

a / sin 27 = 9 / sin 53

a = 9 * sin 27 / sin 53

a = 5.166.

How do fraction tiles help me subtract unlike fractions?
Leokris [45]

Answer:

Step-by-step explanation:

They let you see how one fraction compares to another for one.  Say you had 2/5 and 3/7 it may be tricky to tell which is bigger, but having the tiles will let you see that 3/7 is slightly bigger.  And there are many many more complicated  examples.  So if you know which is bigger you will know subtracting the smaller one will keep it positive, while if you subtract the larger from the smaller one it will be negative.

Also, you can then find equivalent tiles.  In the example I gave you would be able to see 2/5 = 14/35 and 3/7 = 15/35.  Which are like fractions you can subtract simply.

I already give you the answer for number 19 but can you please explain. And then can you tell me what question number 20 is and
madreJ [45]
So, You know the outer angle, so you need to know the inner angle on <B. so 180-148 is 32. since you know two of the inside angles, and all triangle angles add up to 180 degrees, take 32+83, which is 115, and subtract that from 180, which is 65
Hope this helps!

3. Bob the Builder wants to earn an annual rate of 10% on his investments,
mamaluj [8]

Answer:

He should pay $2,790.7.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time, in years.

After t years, the total amount of money is:

T = E + P

In this question:

Rate of 10%, so I = 0.1.

9 months, so t = \frac{9}{12} = 0.75

How much should he pay for a note that will be worth $3,000 in 9 months?

We have to find P for which T = 3000. So

T = E + P

3000 = E + P

E = 3000 - P

Then

E = P*I*t

3000 - P = P*0.1*0.75

1.075P = 3000

P = \frac{3000}{1.075}

P = 2790.7

He should pay $2,790.7.
