Step-by-step explanation:
since the ratio of children to adult is 2:7,
2+7 = 9
number of children would be
(2 × 2700)/9 = 600 children in the crowd
number of adults would be
(7 × 2700)/9 = 2100 adults in the crowd
So, if a ticket costs £8 per adults, total cash made from adult
= 8 × 2100 = £16800
if a ticket costs £(8 - 3) per children, total cash made from children
= 5 × 600 = £3000
total money made = £(16800 + 3000)
= £19800

The rate of change is equal to the slope of a line. Given any 2 points on a line and you can calculate the slope (rate of change) of that line. The formula for rate of change is given by Δy/Δx which equals (y2-y1)/(x2-x1). Therefore, using the points given in the question and simply input them into our formula, we get ((4)-(3))/((-2)-(0)) = -1/2
Answer:
25.35
Step-by-step explanation:
25.2+25.3+25.8+25.1. /. 4
= 25.35
Answer:
An inverse variation is something of the shape:
y = k/x.
Knowing that the point (5, 10) is included in this equation, we can obtain the value of k.
10 = k/5.
10*5 = k
k = 50
Then our inverse variation is:
y = 50/x.
Now we can give any value of x in order to find another point that is included in the variation, for example, if x = 5
y(5) = 50/5 = 10
then the point (5, 10) does also belong to the inverse variation.
if x = 50
y(50) = 50/50 = 1.
then the point (50, 1) does also belong to the inverse variation.
