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

Step-by-step explanation:
Answer:
Slope: 4
Y-intercept: -5
Equation: y=4x-5
Step-by-step explanation:
Slope formula:
So let's use the ordered pairs (1, -1) and (2,3) from the table (it doesnt matter which ones you choose) and plug the numbers in to the formula:
Which is equal to:
Which is equal to 4. So the slope is 4.
To find the y-intercept, substitute the slope and an ordered pair into the slope-intercept equation, y=mx+b. So let's use (1,-1).
-1=4(1)+b
= -1=4+b
= -1-4=4-4+b
= -5=b
So the y-intercept is -5.
Then for the equation, you just plug in the slope and the y-intercept into y=mx+b, which would be:
y=4x-5
Answer:
21 cent per card
Step-by-step explanation:
5.25 / 25 = .21
because 25 can be divided into the first 2 numbers
Part A:
To determine the amount of money in Euros that the team will get, we use the original amount given, the proper dimensional analysis and the conversion factor. For this item,
(£135) x (€1 / £0.72) = €187.5
<em>ANSWER: €187.5</em>
Part B:
Convert first the given length of the arena's stage in centimeters by using the conversion factor, 1 m = 100 cm
(8 meters) x (100 cm/1 m) = 800 cm
Since, both sides will be occupied by 130-cm speaker,
remaining length = 800 - 2(130 cm)
remaining length = 540 cm
<em>ANSWER: 540 cm or 5.4 m</em>
