Answer:
35
Step-by-step explanation:
Since the triangles are similar, we can write a ratio
25 ?
---- = -----
5 7
Using cross products
25*7 = 5 ?
Divide each side by 5
25*7/5 = 5?/5
35 = ?

Answer:
m = 5/6
Step-by-step explanation:
Cross multiply.
1/5 × m = 2/3 × 1/4
1/5 × m = 2/12
1/5 × m = 1/6
m = 5/6
<span>So we want to know how much sand can we store in a cylinder that has height h=5 feet and a radius r=0.5 feet if we need 0.48 ft^3 of sand for a batch of mortar. That is, how many batches of mortair can we make from the sand in the cylinder. So lets first calculate the volume V of the cylinder: V=r^2 * pi * h=3.925 in^3. Now lets divide the volume by 0.48 so we get the unit od sand needed for one batch od mortar: V/0.48= 8.177083. The nearest whole number is 8. </span>
Answer:
Standard numbered cube outcomes are {1, 2, 3, 4, 5, 6}. That makes 6 outcomes, all of them with the same probability to happen. Given that the scenario involves three outcomes with the same probability, one option is to take 1 & 2, 3 & 4 and 5 & 6 as the same result.
