3/4 times 60 = 45
45 mph is the answer
<span>Actually, every square is a rectangle, since the angles in a square
are always right angles. That's more than saying that a square can be
a rectangle; it is one.
</span><span>
And since squares are rectangles, you know that some rectangles are
squares--namely, the squares are!
</span>
<span>We teach children "this is a
rectangle, that is a square. The rectangle's sides are different
lengths". But when you grow up, it's important to think of the square
as a SPECIAL rectangle, because it is all that a rectangle is, and
more.

A square is still a rectangle, but it's not just a rectangle, it's a (pedigreed) square.
In summary, yes a rectangle can be a square.
Hope this helped :)
Given:
The figure of a circle.
Measure of arc = 176°
Measure of angle = (27x+7)°
To find:
The value of x.
Solution:
We know that the measure of central angle is equal to measure corresponding intercepted arc and the measure of central angle is twice of the measure of subtended angle on that arc.
So, the measure of arc is twice of measure of subtended angle on that arc.
Now,
Therefore, the value of x is 3.
Let's say x = full price tickets
Let's say y = student tickets
We can write two equations:
From "585 tickets were sold" we can make the equation:
x + y = 585
And from "Full-price ticket is $2.50 and student ticket is $1.75 and total receipts is $1,217.25"...we can make the equation:
2.50x + 1.75y = 1,217.25
So now we can use substitution to find our answer...since we only have to find how many student tickets...we will solve the first equation for x so we can plug that into the 2nd equation to solve for y.
x + y = 585
x + y - y = 585 - y
x = 585 - y
Now we plug that into our 2nd equation: 2.50 (585 - y) + 1.75y = 1217.25
Distribute your 2.50
1462.5 - 2.50y + 1.75y = 1217.25
Add the y's: 1462.5 - 0.75y = 1217.25
Subtract 1462.5 from both sides:
1462.5 - 0.75y - 1462.5= 1217.25 - 1462.5
-0.75y = -245.25
Divide both sides by -0.75:
y = -245.25/-0.75
y = 327
There were 327 student tickets :)
