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
Answer:
- a) $56000
- b) DA = 2, GA = 10
Step-by-step explanation:
<u>Given</u>
- DA = A + B ⇒ $3000
- GA = A + 2B ⇒ $5000
- Number of A = 12
- Number of B = 22
<u>We can see from the equations that</u>
- GA - DA = B ⇒ $2000 and
- A = $1000 and B = $2000 in terms of profit
<u>So greater use of unit B brings greater profit. We don't want any unit is left over, so get this equation.</u>
Is the equation set to indicate use of the units A and B
<u>Solving we get </u>
<u>It this case all the units are used and profit is maximum</u>
- 2*$3000 + 10*$5000 = $56000
- Number of DA = 2
- Number of GA = 10
Answer:
$1,250
Step-by-step explanation:
You can find the answer using the following formula:
i = Prn
i= interest= $400
P= principal
r= rate of interest=0.04
t= time periods= 8
You can replace the values you have in the formula and then, isolate P:
400= P*0.04*8
400=P*0.32
P= 400/0.32
P= 1250
According to this, the answer is that Anna borrowed $1,250.
Answer: 8 units^2
Step-by-step explanation:
Since both length and width are cut in half by the overlap the new width and lenghth become 8/2=4 and 4/2=2 so 4 and 2
So find area=lxw so 4*2=8
Well, you would do 5+3 which is 8. Then divide 160 and 8. The answer is 20. So now multiply 3 and 20. the answer is 60. Now multiply 5 and 20. the answer is 100. 100+60 is 160. So that checks out. As a result, the 5 would be the boys so the 5 and 20 are 100. So there are 100 boys in the grade.
100 boys
