Can Someone Help Please?

Answers

Answer 1

Answer:

a.  90 degrees (given)

b. 270 degrees (360-90)

c. 16π  (Circumference= diameter * π, diameter= 2r= 2(8)=16, so c= 16*π)

d. 4π (That section is a semicircle, so length should be 1/4 the circumference)

e. 12π (This section is 3/4 the circumference)

f. 64π (Area= πr^2, and r^2= 8^2= 64, so 64π)

g. 16π (That section is 1/4 the area)

Answer:

5/8+1/3=6/11

first u add the fraction and u get the answer of 6/11.

Answer:

7/24

Step-by-step explanation:

5/8 = 15/24

1/3 = 8/24

15/24-8/24 = 7/24

The question was what fraction of all the songs are jazz. Therefore you need to find the common denominator which is 24. (8x3 =24).

Next you Multiply 5x3 which equals 15 and then you multiply 1x8 which equals 8. (We do this because you need to multiply your numerator by the same number you multiplied your denominator with)

Finally, you subtract 8/24 from 15/24 which equals 7. (15-8=7 [make sure you keep your denominator 24] )

Therefore your answer is 7/24

Answers

Answer:

27.4

Step-by-step explanation:

First multiply the numerator and denominator by 10

Then write the problem in long division format

Then multiply the quotient digit (2) by the divisor 19

Then subtract 38 from 52

Then bring down the next number of the dividend

Then divide 140 by 19 to get 7

Then multiply the quotient digit (7) by the divisor 19

Then add a decimal point to the solution

Then bring down the next number of the dividend

Then divide 76 by 19 to get 4

Then multiply the quotient digit (4) by the divisor 19

Then subtract 76 from 76
