Given:
It is given that surface area must be less than 150 cm².
Solution:
The Maximum Volume With Total Surface Area Less than 150 cm² is shown in the table.
From the table, it can be concluded that for r=3.00 cm and h=4.95 cm the surface area will be less than 150 cm² and the volume will be the maximum.
Calculate the volume.
Hence, the required dimensions are r=3.00 cm and h=4.95 cm.
<span>If dog food costs $2 a pound and Cara buys 9 pounds, her expenditure on dog food is 9 x 2. This makes $18. If she has a total budget of $25 and spends $18 on dog food, she has $7 left over for treats (25 - 18 = 7). At $1 each, she can buy up to 7 treats.</span>
When tow solids of similar shape that is assuming to be a box in this case, having a length ratio of 2:9, we get the ratio of the surface areas equal to the<span>square of the ratio of their edges. This is becaue the surface area is equal to the area of the base (square) which is the square of the side. Answer is B.</span>
After Rob has lost, he will have 120 dollars. We can work this out by
establishing that if Rob had 280 dollars before the final competition,
and the ration at the point was 4 to 7, then this means that Tom must
have had 4/7 of what Rob had, so x=4/7 * 280, x = 4 x 40, x = 160. This
means that Tom had 160 dollars and Rob had 280. Adding this together
they have a combined 440 dollars, but the ratio is now 8:3. There are 11
parts to the ration, due to the fact that 8 and 3 is 11, so we need to
work out one part of the ratio - 440 divided by 11 equals forty. This
means that Tom has 8 multiplied by 40 (320 dollars) and Rob has 40
multiplied by 3, so 120 dollars.
Question
The exchange rate at the post office is £1=€1.17 how many euros will you get for £280
Answer:
<h2>
327.6 €</h2>
Step-by-step explanation:
you can solve with an equation
1£ : 1.17€ = 280£ : x
1 : 1.17 = 280 : x
x = 1.17 * 280 : 1
x = 327.6
-------------------
check
1 : 1.17 = 280 : 327.6
0.85 = 0.85
the answer is good
------------------------------------
or you can simpy solve with a multiplication
280 * 1.17 = 327.6
