Answer:hey mate,
To find x u will have to equate it to 360
90+56+68+2x=360
214+2x=360
2x=146
x=73
Hope this helps you...
Step-by-step explanation:
Answer:
a) 5:3
b) 7.5:5.3
Step-by-step explanation:
150min : 90min (1 and a half hour)
10 : 6
5 : 3
150 × 10 mm : 1060 mm
1500 : 1060
750 : 530
7.5 : 5.3
5.47 is the square root of 30.
Answer:
The graph of the function rule will be a line segment connecting (0,2) and (40,22) as shown in the graph below.
Step-by-step explanation:
Given:
The function rule representing the total cost of ride and number of miles traveled is:
Now, the maximum value of 
is 40.
So, the maximum cost of ride is given as:
So, the graph of the given function rule has a domain between 0 and 40 and range is between 2 and 22.
The graph is shown below.
Male to female is 8:5
So
Let's make male = 8x
female = 5x
8x-400/5x-300=8/3
The 8/3 is because that is what the ratio was after some of the students left
multiply by 5x-300 on both sides
8x-400=(5x-300)*(8/3)
multiply by 3 on both sides to remove the denominator
(8x-400)*3=(5x-300)*8
24x-1200=40x-2400
+2400 +2400
24x+1200=40x
-24x -24x
1200=16x
divide by 16
1200/16=16x/16
75=x
Now to find total we do 8x+5x we said male were 8x and female were 5x
8(75)+5(75)
600+375=975 total students
