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
Answer:
a) Angle XBC = 55° because it is a corresponding angle to 55°
b) angle BXC = 70°
Step-by-step explanation:
ΔXBC is an isosceles triangle because XB = XC
∠XCB = ∠XBC because ΔXBC is an isosceles triangle
∠BXC = 180° - 55° - 55° = 70° because the sum of all the interior angles of a triangle - 180°
<span>The side of the patio that is 12 feet is equal to 144 inches. 144 inches divided by 8 inches for each stone tells you that you can fit 18 stones along this edge. The side of the patio that is 14 feet is equal to 168 inches. 168 divided by 8 is 21, telling you that 21 stones fit along this edge. By multiplying the number of stones on each edge, you can find the total number of stones needed. 21 times 18 equals 378 stones to pave the whole patio.</span>
