Answer:
Im not sure about 20 but 22 is 48
Step-by-step explanation:
4×96 =384
384÷8 = 48 orange per classroom
Answer:
There were 172 guests that were children and 278 guests that were adults
Step-by-step explanation:
Step 1: State what is known
It is $25 per adult
It is $12 per child
The made $9014 dollars
There were 450 guests
Step 2: Define equations
25y + 12x = 9014 -----1
x + y = 450 ------------2
Step 3: Rearrange equation 2 for x
x + y = 450
x = 450 - y --------------3
Step 4: Substitute 3 into 1 for y and solve for y
25y + 12(450 - y) = 9014
25y + 5400 - 12y = 9014
13y = 3614
y = 3614/13
y = 278
Step 5: Substitute y = 278 into 3 to solve for x
x = 450 - (278)
x = 172
Therefore 172 children and 278 adults visited the museum
Answer:
y = 
x
Step-by-step explanation:
Given that the quantities vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use either of the 2 given points
Using (12, 9), that is x = 12 when y = 9, then
k = 
= 
=
y = x ← equation of variation
Answer:
15 dollars.
Step-by-step explanation:
That would be 60% of 25
= 25 * 0.6
= 15 dollars.
Answer:
Step-by-step explanation:
The following are the given information:
- The handicapped spot, which is
feet wide and next to the curb. - The other three spots are
feet wide. - There are 4 dividing lines between the spots, and each measures
foot.
The Median D therefore will be a sum of the following:
- The width of the Handicapped Spot
- 3 X The width of the other spots
- 4 X The width of the dividing line
