Answer:
$24.50
Step-by-step explanation:
Since we know that 3 child tickets are $18.50 each, let's find out the total price of the child tickets.
18.50 x 3 = $55.50
Since we don't know the cost of each of the adult tickets, let's call it x.
Now let's make an equation!
55.50 + 2x = 104.50
Now we have to isolate x in order to find out the price of each adult ticket.
Let's subtract 55.50 on both sides
2x = 49
Now let's divide 2 on both sides.
x = $24.50
So the price of an adult ticket is $24.50
CHECK:
55.50 times 2 (24.50) = 104.50
Answer:
Neither.
Step-by-step explanation:
The slope for the first one is 1/4 and the slope for the second one is 4. These are reciprocals, but not opposite reciprocals, meaning they are not perpendicular. An opposite reciprocal means the fraction is flipped (ex. 3/1 to 1/3) and the sign is changed. The line parallel to y=1/4x would be y= -4x.
Answer:
for the first answer your answer was correct, it was the second answer that was wrong. So the first answer is 2 3/4. The second answer would be 81 centimeters because it grew that much.
Step-by-step explanation:
To find the first answer add the starting height and ending height. To find how much it grew convert the total ending height of the tree to cm by multiply by 100, so 275. Then subtract 356 by 275 because you are finding out how much it grew. Take away 275 from 356 and you get 81
Direct variation looks like
y=kx, so
k=y/x
<span>(2, 4) k=4/2=2
(5, 10) k=10/5=2
(7, 14) k=14/7=2
(11, 22) k=22/11=2
Answer:A.k=2.</span>
The equation for the area of a circle is:
A=π*radius squared.
Since radius is half of the diameter.
Diameter/2=radius
Then plug it into the equation.
