Answer:
<h2>$4.7</h2>
Step-by-step explanation:
step one:
Let the cost be y
to solve for the cost of a movie ticket, we need to solve the expression
y=2.75+0.10x
step two:
given that x is the number of years between 1980-2000
the number of years is 20years
put x= 20 in the expression for the cost we have
y=2.75+0.10(20)
y=2.7+2
y=$4.7
Answer:
2. x + 98 + 50 = 180
3. x = 32°
Step-by-step explanation:
<em>hey there,</em>
< 2. We know that there are 180 degrees in every triangle, and every triangle has only 3 angles. So when you add up those 3 angles, it will ALWAYS equal 180! And since we do not know one of the angles, we will just put the value of that angle as "x" into the equation.
3. Here, you should be able to find x! x = (180-(98+50)) = 32
The final answer is 32 degrees. >

Answer:
Step-by-step explanation:
This shape is called a rectangular prism. The formula for finding the volume of this prism is: 
All you do is plug the values into the formula.
The length is 2m
The width is 1m
the height is 5m
Volume = (2m)(1m)(5m)
Volume =

Answer:
Step-by-step explanation:
The pythagorean theorem goes: a^2 + b^2 = c^2
c is the hypotenuse of the right triangle, the longest side.
This means that by squaring the two shorter sides of an answer choice and seeing if they are equal to the longest side squared we can see if that answer choice contains the sides of a right triangle.
So, for example, lets look at answer choice B. 4.5^2 + 3^2 = 29.25 and 7.5^ = 56.25
29.25 is not equal to 56.25 so B is incorrect.
Doing the same process with answer choice A gets us: 6^2 + 2.5^2 = 42.25 and 6.5^2 = 42.25
This means a^2 + b^2 equals c^2 and answer choice A is our correct answer.
