Answer:
We want to simplify:
(3 + 1/4)*(3/5)
The first step is to write the first term as a single rational number.
We know that:
3*1 = 3
and 4/4 = 1
then:
3*1 = 3*(4/4) = (3*4)/4 = 12/4
We do this because we want to have the same denominator in both numbers, so we can directly add them.
Then we get:
(3 + 1/4)*(3/5) = (12/4 + 1/4)*(3/5) = (13/4)*(3/5)
And remember that in the multiplication of rational numbers the numerator are multiplied together and the same for the denominators, then we get:
(13/4)*(3/5) = (13*3)/(4*5)
If we solve the multiplications we get:
(13*3)/(4*5) = (39/20)
Now, we can notice that in the numerator we have two prime numbers, 13 and 3.
And in the denominators, we have a 4 (which is equal to 2*2) and a 5.
So the prime numbers in the numerator and the denominator are all different, this means that we can not simplify it furthermore.
Then we have:
(3 + 1/4)*(3/5) = (39/20)
Answer:
The mean number of cookies was 33.5
Step-by-step explanation:
Add the values of the terms and divide by the number of terms.
So...
26 + 38 + 45 + 25 = 134
134 ÷ 4 = 33.5
Answer:
1) 24.2 = x 2) 27.8 = x
Step-by-step explanation:
1) Find the cos 21 degrees
cos 21 = x/26 Simplify
0.93 = x/26 Multiply 0.93 and 26
24.2 = x
2) Find the sin 33 degrees
sin 33 = 15/x Simplify
0.54 = 15/x Divide both sides by 0.54
27.8 = x

The answer is D
Have you ever heard of rise over run rise/run
Y/x. Well in this case the run is One with a rise of four
6,000 because its in the thousandth and so since its a six in the thousandths its 6,000 remember the comma
