Answer:
(B) $15
Step-by-step explanation:
Big Video: y = 2.49x + 9.99
Main Street: y = 1.79x + 20.49
easiest way to solve would be to graph and find the point of intersection or set 2.49x + 9.99 and 1.79x + 20.49 equal to each other
2.49x + 9.99 = 1.79x + 20.49
subtract 1.79x from each side to get:
.70x + 9.99 = 20.49
subtract 9.99 from each side to get:
.70x = 10.50
divide each side by .70
x = 15
Answer:
54000
Step-by-step explanation:
First, round.
75572=76000
22468=22000
Then solve.
76000-22000=54000
Answer:
She can make 55 bracelets
Step-by-step explanation:
We have the correct question as follows;
Ariel bought a 15 1/6 foot long string, and a 12 1/3 foot long string. If each bracelet requires 1/2 of a foot long string, how many bracelets can Ariel make
we have the solution as follows
Firstly, we need to find the total length of the strings bought
We can get this by adding what was bought
That would be;
15 1/6 + 12 1/3
= 91/6 + 37/3
= (91 + 74)/6 = 27 1/2 ft
From the question, each bracelet requires 1/2 ft long
so the number of 1/2 ft long bracelets we can find will be;
27 1/2 divided by 1/2
= 55/2 * 2/1
= 55
Answer:
Matched pairs design
Step-by-step explanation:
A matched pair design can be used in a case where the same people are being measured in before-and-after comparison. The same set of people are measured for the amount of sleep each night before the administration of the drugs and after the drug administration and this is used to test for a difference.
