Answer:
32 yd^2
Step-by-step explanation:
Ignore rounded approximations (i.e. 2.66, 1.33). For all calculations, use fractions and EXACT values.
This prism has 6 surfaces:
- Front: 3 x 2.66 = 8
- Back: 3 x 2.66 = 8
- Top: 3 x 1.33 = 4
- Bottom: 3 x 1.33 = 4
- Side: 1.33 x 2.66 = 4
- Side: 1.33 x 2.66 = 4
Total SA: 8(2) + 4(4) = <u>32 yd^2</u>
Answer:
Answer:1134
Step-by-step explanation: first you do (21×7×2)+(12×10×7) then once you do that you'll get 1134 and that's your answer.
C. The answer is C because the total amount of students is 14, and there are 4 boys, which makes the ratio 4 boys to 14 students in total. 4 and 14 are both divisable by 2, so divide 4 to get 2 and divide 14 to get 7. This leaves you with 2 and 7. The ratio would be 2 boys to 7 total students. Hope this helped
Answer:
Step-by-step explanation:
2 l + 2w = 34 ⇔ l + w = 17 ⇒ l = 17 - w ..... <em>(1)</em>
l w = 66 ..... <em>(2)</em>
<em>(1)</em> ----> <em>(2)</em>
(17 - w) w = 66
w² - 17w + 66 = 0 ⇔ (w - 6)(w - 11) = 0
w = 6 cm
l = 11 cm
