Answer:
Below
Step-by-step explanation:
Use the formula 2πr^2 + 2πrh to find the Surface area of a cylinder
A = 2π(11)^2 + 2π(11)(11)
= 1520.53084....
Rounding to the nearest 10th
= 1520.5 in^2
Hope this helps!
<em>x</em> = amount invested at 8 %. Then 23 000 - <em>x</em> = amount invested at 9 %
Annual income (<em>I</em>) = interest at 8 % + interest at 9 %
<em>I</em> = 0.08<em>x</em> + 0.09(23 000 – <em>x</em>)
<em>I</em> = 0.08<em>x</em> + 2070 – 0.09<em>x</em>
<em>I</em> = 2070 – 0.01<em>x</em>
Single solution.
They have different slopes and must therefore have 1 solution.
Answer: Omar can make 14 whole dumplings.
Step-by-step explanation: Make 2 3/4 an improper fraction. To do this, multiply 2 by the denominator, 4. From this, you get 8. Then add 8 to the numerator, which is 3, and you get 11. Keep the denominator and you'll have 11/4.
To divide fractions, you make 3/16 its reciprocal by basically flipping the fraction so that the numerator becomes the denominator and vise versa, making it 16/3. Then multiply 11/4 and 16/3. 11 x 16 is 176; 4 x 3 is 12. The result is 176/12. Simplify by dividing the numerator and denominator by 4. Your resulting answer should be 44/3. Simplify even further by simple division. Your final answer should be 14 2/3. Discard the 2/3 because Omar needs to make whole dumplings. So the answer is 14.
I believe the answer to question 2 is the first option, and the answer to question 3 is the last option
