Answer:
Im dumb but cant you just be like, I subtracted 146° and 62°?
We will solve this using a system of equations. The first part tells us that building a is 190 feet shorter than building b. Our first equation, then, is b=190+a. The second part tells us that the addition of the two buildings' heights is 1480. So our second equation is a + b = 1480. The first equation is already solved for b, so let's sub that value into the second equation for b: a+(190+a)=1480. 2a + 190 = 1480 and 2a = 1290. That means that building a is 645 feet tall. Building b is 190 feet taller, so b = 190 + 645, which is 835.
Answer:
The value of the given expression is 84.
Step-by-step explanation:
The given expression is
The number 252 can be written as 240+12, because 24 can easily divisible by 3.
The compatible numbers are 240 and 12
Therefore the value of the given expression is 84.
Formula:
V = 1/3 * pi * r^2 * h
Plug in what we know:
V = 1/3 * 3.14 * 3^2 * 4
V = 37.68cm^3
So the volume is 37.68cm^3 which rounds to 37.7cm^3.
Answer:
Hey there!
A congruence transformation maintains the size of the shape.
Thus, a dilation with scale factor 2 is not a congruence transformation.
Let me know if this helps :)
