Answer:
a. parallel b. neither c. neither d. perpendicular
Step-by-step explanation:
Find the gradient of the line in the graph
Choose 2 coordinates, I choose (0,1) and (3,3)
Use the formula
(y2 - y1)/(x2 - x1)
(3 - 1) / (3 - 0)
2/3
Gradient of a parallel line is the same
Gradient of a perpendicular line formula m1m2 = -1
(2/3)m2 = -1
m2 = -3/2
The gradient of the perpendicular line will be -3/2
The gradient of the parallel line will be 2/3
Any other gradient will be neither parallel nor perpendicular.
Answer: 57 boys
Step-by-step explanation: Lets break it down right
14th from the top with 10 girls in front which means 3 boys are in front and since there are twice as many girls as boys there are 60 girls and 30 boys so 3 boys are ahead which leaves 57 boys below him
$1495 ÷ 1.15 (that's 115%)
= $1300
there's your wholesale price.
we can check it to make sure it's correct:
$1300 × 1.15 = $1495
Answer:
$1551 needed to cover the costs and 141 shirts will be sold.
Step-by-step explanation:
If a shirt costs $10 and the council is selling the shirt for $1 more ($11), after selling 141 shirts, they would have made a profit of $1*141=$141. Since there is also a setup fee of $141, the profit would actually be $0. This is when the costs are covered.
C = 10s + 141 (C is cost and s in no. of shirts sold)
s = 141
C = 141*10 + 141 = 1551
Hope this helps!
