Answer:
C) 4 pencils for each student
D) 8 students per team
Step-by-step explanation:
A unit rate is the number of unit of the first type of a quantity corresponding to one unit of the second type of quantity.
That is, if a and b are two quantities,
Then, unit rate of quantity a = x units of 'a' per 1 unit of 'b' or x units of 'a' for 1 unit of 'b'
By the above statement,
The example of unit rates from the given options are,
4 pencils for each student,
8 students per team
Let j = cost of one jumbo popcorn, and c = cost of one chocolate chip cookie.
Then, based upon the given info, 1j + 2c = $5.
Also, 3j + 5c = $14.50
Let's solve this system of equations using addition/subtraction:
Mult. the first equation by -3, to obtain -3j - 6c = -$15
Now add this result to the 2nd equation:
-3j - 6c = -$15
3j + 5c = $14.50
----------------------
-c = -$0.50, or c = $0.50. Since 3j + 5c = $14.50, subst. $0.50 for c
lets us find j:
3j + 5($0.50) = $14.50, so 3j = $12.00. Thus, j = $4.00.
Jumbo popcorn is $4/bag, and choc. chip cookies $0.50 each.
Answer:
Step-by-step explanation:
y intercept is when x = 0
So, Putting x = 0 in the above function
=> f(0) = 
=> f(0) = 2*1
=> f(0) = 2
So, y-intercept is (0,2)
Answer:
B x = sqrt(48)
Step-by-step explanation:
Half of the bottom side measures 4.
4^2 + x^2 = 8^2
16 + x^2 = 64
x^2 = 48
x = sqrt(48)
Answer: B x = sqrt(48)
