Answer:
C
Step-by-step explanation:
Answer is (1) 160 km in 2 hours and
(2) 16 miles in 12 minutes.
Step by step.
80 km / 1 hour = x km /2 hours
Cross multiply =
x = 160
The second one requires a little more math. Because we are looking at how far in minutes, we change the rate of 80km in 1 hour to 80 km in 60 minutes.
80 km / 60 = x / 12
Cross multiply
12x = 960
Solve for x by dividing both sides by 12
X = 16
I did the math on a print screen to explain the cross multiply.
Answer:
Step-by-step explanation:
Difference in the distance = 50 yards
Difference in speed = 8 - 6 = 2 y/s
<u>Time to cover the gap is:</u>
<u>Sandra will run the distance:</u>
The key word here is "or". If it's an OR question, you add the probabilities together. If it says "and", you multiply them together
As it is an OR question though, you add them.
So:
15 + 5 = 20%
Hi Eli!
--------------------------------------
We Know:
1 1/2 cups of flour.
3/4 cup of white sugar.
1/8 cup of brown sugar.
--------------------------------------
Part A:
I can't use a number line answering this question but you can create one with the steps I tell you.
First find common denominators:
1 1/2 = 3/2 = 12/8
3/4 = 6/8
1/8
Create a number that goes from 0/8 to 12/8, which means put a number with 12, 1/8 plots on it. Then plot 12/8, 6/8, and 1/8 in order in the number line.
Find out the total number of cups used:
12/8 + 6/8 + 1/8 = 19/8
Simplify:
19/8 = 2 3/84
Part A Answer: There are <u>2 3/8 cups</u> used all together.
--------------------------------------
Part B:
Part B Answer: The <u>3 cup bowl</u> would work perfectly.
Why: The reason you would want to choose the 3 cup bowl is because it fits all the ingredients perfectly, the 3 cup bowl is greater than the 2 3/8 cups they used. You can't use 2 cups because it is less than the total cups of ingredients. The 4 bowl you could use but it is too big.

Hope This Helps :)
