Answer:
Mai
Step-by-step explanation:
To find the rate, you must determine who is going faster per minute. To do this, you must divide the total number of miles by the total number of minutes.
Mai: 5 miles / 15 minutes = 1/3 miles per minute
Jada: 4 miles / 14 minutes = 2/7 miles per minute
Then, use a common denominator to make calculations easier:
Mai: 1/3 * 7/7
Jada: 2/7 * 3/3
You should get:
Mai: 7/21 miles per minute
Jada: 6/21 miles per minute
By looking at this, you can see that Mai is traveling slightly faster, going more miles than Jada per minute.
A unit rate is a ratio that has a denominator of 1. A unit rate is also called a unit ratio. (They mean the same thing.)
\frac{5}{4} and 3:8 and 40\mbox{ to }10 are ratios, but they are not unit ratios.
\frac{1.25}{1} and 0.375:1 and 4\mbox{ to }1 are unit ratios.
Any ratio can be converted into a unit ratio by dividing the numerator and the denominator by the denominator.
Answer: -9
Step-by-step explanation: You are not doing 3(-2) to get -6. That's incorrect. What you are supposed to do is multiply the base which is 3 and then multiply it with -2 so that would 3(3) twice and don't forget the negative in front of the two so that would be -9 as the correct answer. :)
Interest paid by Linda is equal to $4.272 approximately equal to $4.27.
<u>
Solution:
</u>
Given that
Rate of interest on first $200 = 1.8%
Rate of interest on any amount over $200 = 1.2%
Unpaid balance amount of Linda’s credit card bill = $256
Need to calculate interest paid by her on $256.
Unpaid balance = $256
=$200 + 56
Amount over $200 = 56
Interest paid on first $200 = 1.8% of 200
= 0.018 x 200 = $3.6
Interest paid on amount over $200 that is $56 = 1.2% of 56
= 0.012 x 56 = $0.672
So total interest paid on $256 = 3.6 + 0.672 = $4.272.
Hence interest paid by Linda is equal to $4.272 approximately equal to $4.27.
The missing angle is 27° because a triangle equals 180° and 180-119=61 and 61-34= 27.
