Answer: 15.75 or 15.73
Step-by-step explanation:
13.48/6=2.2466666667
Round to the nearest hundredth
Then, it will be 2.25
Next, you multiply,
When rounding this is your answer 2.25 x 7 = 15.75
OR
2.2466666667 x 7 = 15.72666667
When rounded it’s 15.73
99,019,900 would be ninety-nine million nineteen thousand and nine hundred hundred
Answer:
D
Step-by-step explanation:
She spent $12 and *$ on two separate things, meaning she spent $20 on both.
So, 12 + 8 = 20.
If she started with 25, we subtract 20 from 25 to get how much she has left.
So, 25 - 20 = y.
Therefore, the answer is D.
Let the original price be x
selling price = $34
discount = 15%
Therefore S.P. = 100-15/100 * x
So, x = 34 * 100/85
= 3400/85
= $40
Still begging? OK. Let's do it with algebra first then put in the numbers.
We're given the Circumference of a circle C, and we want the area A.
The radius is related to the circumference by
C = 2π r
The area is related to the radius by
A = π r²
Solving for r in the first equation,
r = C/(2π)
So the area is
A = π ( C/(2π) )² = πC²/(4π²) = C²/(4π)
---------------------------
OK we're given C=25 1/7 inches, π≈22/7
C = (7×25 + 1)/7 = 176/7 = (22×8)/7
That's a little convenient.
A = C²/4π = ( (22×8)/7 )² / (4 (22/7) ) = (8²/4) (22/7) = (16*22)/7 = 352/7
After those nice numbers they want an approximation. How disappointing.
A = 50.2857142857 sq inches
Answer: 50.29
