Answer: A.
Step-by-step explanation:
Plot the y-intercept (0,-1) and use the slope of 1/4 to find a second point
Answer:
15
Step-by-step explanation:
Let the number of adult tickets be x while children ticket be y. Since the total tickets were 20 then we can form the equation
x+y=20
Making x the subject then x=20-y
Considering the cost of each ticket
15x+10y=225
Substituting x with 20-y then
15(20-y)+10y=225
300-15y+10y=225
Collecting like terms
300-225=15y-10y
75=5y
Y=75/5=15
To find x, we already know that x=20-y hence x=20-15=5
Therefore, children tickets are 15 while adult tickets are 5.
The question only needs us to know the children tickets, y which is 15

Answer:
- 3 large boxes
- 9 small boxes
Step-by-step explanation:
The purchase can be grouped into groups containing one large box and 3 small boxes. Then each group will have 12 +3·6 = 30 granola bars.
Since 90 bars were purchased, the camp bought 90/30 = 3 groups of boxes of bars.
They purchased 3 large boxes and 9 small boxes of bars.
A.
h = 14 ft · sin 30° = 14 ft · 0.5 = 7 ft.
b.
From the bottom of the height to the bottom of the slide:
y² = 14² - 7² = 196 - 49 = 147
y = √147 = 12.12 ft
15 ft - 12.12 ft = 2.88 ft ( from the bottom of the stairs to the bottom of the height )
tan x = 7 / 2.88 = 2.43
∠x = tan^(-1) 2.43
∠x = 67.63° ≈ 68°.
