Answer:
Least common denominator of 2 and 8: 8
5 x 1 = 5
8 x 1 = 8
1 x 4 = 4
2 x 4 = 8
Step-by-step explanation:
5/8 and 1/2 are not equivalent; the wording is weird on this question, it almost makes it sound as if it wants you to make 5/8 and 1/2 equivalent fractions.
I assume it only wants you to set it up so that in part 2 you will be able to easily figure out how much wire Mr. Barber has used total. Which will be 9/8 yards, by the way. Alternatively, 1 1/8 yards.
The equation for the line that passes through the points (2,2) and (4,-2) would be y = -2x + 6.
Hope this Helps!!

Answer:
-90 , 30
Step-by-step explanation:
sina = cos(2a)
= 1 - 2(sina)^2
2(sina)^2 + sina -- 1 = 0
( sina + 1 )( 2sina - 1 ) = 0
sina = -1 or sina = 1/2
=> a = -90 degrees or => a = 30 degrees
Answer:
x = 20,000
p = $40
If the price increase by $1, the demand will decrease by 1000
Step-by-step explanation:
Given:
x = 160 - p
x = number of Robby costumes demanded in thousands
p = price in dollars.
a. How many costumes can be sold at a price of $140?
x = 160 - p
x = 160 - 140
= 20
x = 20,000
20 thousand costumes can be sold at a price of $140
b. What price should be charged if the demand is 120,000 Robby costumes?
x is in thousand
p is in dollars
x = 160 - p
x + p = 160
120 + p = 160
p = 160-120
= 40
p = $40
c. If the price increases by $1.00, by how much does the demand decrease?
x = 160 - p
= 160 - 141
= 19
x= 19,000
If the price increase by $1, the demand will decrease by 1000
