Answer:
A. 11160 cubes B. 1395cm^3
Step-by-step explanation:
Volume= length x width x height
Its easiest to solve B. first and use it to solve A.
B. 7.5 x 12 x 15.5 = 1395cm^3 (volume of prism)
A. .5 x .5 x .5 = 1/8cm^3 (which is the volume of the cube)
1395 ÷ 1/8 = 11160
Answer:
<u>The correct answer is A. 14 x + 6 y = 10. Negative 14 x minus 35 y = 77</u>
Step-by-step explanation:
Let's find out the constants to eliminate the x terms
7 x + 3 y = 5
2 x + 5 y = negative 11
Let's multiply the first equation by 2 and the second one by -7, this way:
2 * (7 x + 3 y = 5)
-7 * (2 x + 5 y = negative 11)
14x + 6y = 10
-14x - 35y = 77
<u>The correct answer is A. 14 x + 6 y = 10. Negative 14 x minus 35 y = 77</u>
For this case we have the following expression:
From here, we must clear the value of a.
We then have the following steps:
Place the terms that depend on a on the same side of the equation:
Do common factor "a":
Clear the value of "a" by dividing the factor within the parenthesis:
Answer:
The clear expression for "a" is given by:
Answer:
y < 3
Step-by-step explanation:
Let slant height be s
Height = 38yd. = h
Side = 42yd. = a
S² = h² + (a/2)²
= 38² + 21²
= 1444 + 441
= 1885
S = √1885
S = 43.42yd.
Lateral area = 1/2 × 4a × s
= 2 × 42 × 43.42
= 3646.99
= 3647 yd.²
