Step-by-step explanation:
as any other fully symmetric 3D object, the volume is
base area × height.
the area of a circle is
pi×r²
so, we have in our case
pi×13²×9 = 3.14×169×9 = 4,775.94 cm³
Answer:
Ted pays $47.98 before tax
Step-by-step explanation:
What was the cost of the purchases before the coupon
pole + bait+ shorts
35.99 + 12.99+14.99
63.97
If we take 25% off, we still have to pay (100% -25%) or 75%
take the purchases times 75%
63.97 * .75
47.9775
round to the nearest cent
47.98

√49 - √1
Step-by-step explanation:
Answer:
x<1
Step-by-step explanation:
The answer can be readily calculated using a single variable, x:
Let x = the amount being invested at an annual rate of 10%
Let (8000 - x) = the amount being invested at an annual rate of 12%
The problem is then stated as:
(x * 0.10) + ((8000 - x) * 0.12) = 900
0.10(x) + ((8000 * 0.12) - 0.12(x)) = 900
0.10(x) + 960 - 0.12(x) = 900
0.10(x) - 0.12(x) = 900 - 960
-0.02(x) = -60
-0.02(x) * -100/2 = -60 * -100/2
x = 6000 / 2
x = 3000
Thus, $3,000 is invested at 10% = $300 annually; and $8,000 - $3,000 = $5,000 invested at 12% = $600 annually, which sum to $900 annual investment.
