Answer:
141.46 mi/h
Step-by-step explanation:
d = rt
r = d/t = (2440.2 mi)/(17.25 h) ≈ 141.46 mi/h
The woman's average speed was about 141.46 mph.
Answer:
0.45 / ![\frac{9}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B20%7D)
Step-by-step explanation:
![(-\frac{1}{2} )(\frac{3}{5} )+\frac{3}{2} -\frac{3}{5} (\frac{5}{4} )](https://tex.z-dn.net/?f=%28-%5Cfrac%7B1%7D%7B2%7D%20%29%28%5Cfrac%7B3%7D%7B5%7D%20%29%2B%5Cfrac%7B3%7D%7B2%7D%20-%5Cfrac%7B3%7D%7B5%7D%20%28%5Cfrac%7B5%7D%7B4%7D%20%29)
![=\frac{9}{20} / 0.45](https://tex.z-dn.net/?f=%3D%5Cfrac%7B9%7D%7B20%7D%20%2F%200.45)
3, because if it only makes 10 cupcakes, you need to triple it (i.e. 10*3=30); (Assuming it was 1 cup oil) 3 cups vegetable oil; 3 cups flour; the difference is 2 teaspoons; (Assuming it was 1 teaspoon salt) the difference is 2 teaspoons; It would make sense to round the bananas because "medium-sized bananas" depends on your personal opinion, which means it's already rounded and further rounding wouldn't hurt as long as you're careful.
Answer:
<h2><u>
10</u></h2><h2><u>
4</u></h2>
Step-by-step explanation:
To determine how much a decimal was multiplied, you need to find how many places the decimal moved.
In this case we can see the decimal moved once. How many times the decimal moved can be represented by the zeros in the number. So 10 = 1
100 = 2 1,000 = 3 and it keeps going.
So since the decimal moved 1 time, the answer to question one is 10
Now question 2.
Both 8.4 ÷ 2.1 and 84 ÷ 21 will give the exact same answer. It is just easier to solve. So solve which one is easier for you. I did 84 ÷ 21.
84 ÷ 21 = 4
We can verify our answer by multiplying the the divisor by the quotient
21 * 4 = 84
So 4 is the answer to question 2
