Answer:
okay so the first one ull need to kno pemdas so start with the perenthesis (5^2-10) and then the exponent 2^3 and multyply thats by 5 and what ever answer u got in the perenthisis u divide by what u got with the second side of the problem
Step-by-step explanation:
if u need more help ill tutor u on it :)
Volume of a cone can be found using the equation 1/3 π r² h (or π r² h / 3)
r = 11
h = 4.5
π ≈ 3.14
(1/3) (3.14) (11²) (4.5) =
(1/3) (3.14) (121) (4.5) =
(1/3) (3.14) (544.5) =
(1/3) (1709.73) = 569.91
569.91 rounded to the nearest tenth is 569.9 so your answer would be 569.9 in³
Answer:
220ft^2
Step-by-step explanation:
In red: 12ft - 10ft = 2ft and there 2 sides so 2ft / 2 = 1ft
In blue: 18ft - 12ft = 6ft
The missing area in dark blue: 6ft x 1ft = 6 / 2 = 3
total rectangle area: 12ft x 18ft = 216
216 - (3 + 3) = 216 - 6 = 200 subtract 6, we added that area in
Answer: a. You must pay $11.19 for the item.
b.The price you would expect to pay would be $36.59
Step-by-step explanation:
Hi, for first the question you need to calculate the 30 percent of the price of the item, and then subtract that result to the original price.
So: $15.99 × 0,30 = $4.797
$15.99 - $4.797 = $11.19
You must pay $11.19 for the item.
It´s a similar resolution, first you calculate the 40 percent of the retail price, and then subtract that result to the retail price.
So:
$60.99 × 0,40= $24.396
$60.99 - $24.396 = $36.59
The price you would expect to pay would be $36.59
