Answer: 7 3/4 - 2/25 = 767/100 = 7 67/100 = 7.67
Step-by-step explanation:
Conversion a mixed number 7 3/4
to a improper fraction: 7 3/4 = 7 3/4 = 7 · 4 + 3/4= 28 + 3/4 = 31/4
To find a new numerator:
a) Multiply the whole number 7 by the denominator 4. Whole number 7 equally 7 * 4/4 = 28/4
b) Add the answer from previous step 28 to the numerator 3. New numerator is 28 + 3 = 31
c) Write a previous answer (new numerator 31) over the denominator 4.
Seven and three quarters is thirty-one quarters
Subtract: 31/4 - 2/25= 31 · 25/4 · 25 - 2 · 4/25 · 4 = 775/100 - 8/100 = 775 - 8/
100 = 767/100
A = 1/2aP
P = number of sides x length of each side
P = 8 x 5.8
P = 46.4
A= 1/2 x 7 x 46.4
A = 162.4
Answer:
1 / 36
Step-by-step explanation:
So there's one number on a cube greater than 5. That is 6.
There is 1 / 6 chance of getting 6 the first time, and another 1 / 6 change for getting 6 the second time.
1 / 6 * 1 / 6 = 1 / 36
Answer: 82
Step-by-step explanation:
We know that ADC is the angle bisector
So BDC and BDA are two equal angles
So 164 divided by the two equal sides gives us 82 on each side
