The answer is B) n+6. Simply because penny is 6 inches taller than Claire, which means you would have to add 6 inches to Claire's height to reveal penny's height. Also n represents Claire height which makes the expression easier to figure out.
So to add fractions they need to have a common denominator, which in this case is 24. then multiply 1 by 4 and 5 by 3 because whatever you multiply the denominator by you need to do the same to the numerator, which will get you 4/24+15/24 then you add across the numerators and you get 19/24
Answer:
The number of vocalist sang on the end of the 10th day is 6138 vocalist.
Step-by-step explanation:
Given:
Number of vocalist needed on the first day = 6
Each day after that, the number of vocalists needed doubles
To Find:
The total number of vocalist found on the 10th day = ?
Solution:
By using the geometric series
Where
a is the first term
r is the ratio
n is the number of terms
On substituting the values
That is
The first day = 6 vocalist
Second day = 12 vocalist
third day =24 vocalist
Fourth day =48 vocal list
Fifth day = 96 vocalist
Sixth day = 192 vocalist
Seventh day = 384 vocalist
eight day = 768 vocalist
Ninth day = 1536 vocalist
Tenth day = 3072 vocalist
So
6+12+24+48+96+192+384+768+1536+3072 = 6138 vocalist sang in total on the end of tenth day.
Answer:
Kate finished the race in 52 seconds
Alexia finished the race in 58 seconds
Trina finished the race in 49 seconds
Step-by-step explanation:
From this work problem we can set up these series of equations:
First we need to create only one variable in the first equation in order to solve it, so we can substitute in the other equations into the first one. That would look like this
Then we can simplify this
Now that we solve for Kate's time, we can use the other 2 equations to find the times of Alexia and Trina
Using the equation for Alexia's time and plugging in Kate's time gives us
Using the equation for Trina's time and plugging in Kate's time give us
