Answer:
125
Step-by-step explanation:
In ΔPTO we are given that
∠PTO = 90° (indicated by the right angle)
and ∠TPO = 35°
And we need to find the exterior angle (∠TOB)
If you didn't know this is the rule about exterior angles
Exterior angles of a triangle are equal to the sum of the opposite interior angles of a triangle
So more specifically for this problem
∠TOB = ∠PTO + ∠TPO
Now that we have created an equation we want to plug in the values that we are given
∠TOB = 90 + 35
90 + 35 = 125
Therefore the answer is 125
Alex spent 25% first, so he has now 75%. Then, he spent another 25% of that remaining money, so 25% of 75% is 56.25%. He has $9 left, which means $9 is 56.25% of the money he began with.
Set up a proportion:
9/x = 56.25/100 (9 dollars out of starting money equals to 56.25 per 100)
cross multiply 9 and 100, 56.25 and x
900=56.25x
Isolate the variable by dividing each side by 56.25
x=$16
Volume of a cylinder= πr^2h
=πx3x3x7
=63π cubic units
The answer would be B, 5. Hope this helps!
I might be wrong but I’d say the answer is B). Tim must work at least 6 hrs....
I say this cuz the open circle in an equation and on the graph line represents less than/more than or equal too. In this case (on a graph) it means more than or equal too so letter b makes more sense to me
