75 x 15= 1,125
1,125/100=11.25
75-11.25= 63.75
Answer:

Step-by-step explanation:
So we want to make x the subject of the formula:

First, distribute the left side:

Combine all the terms with x with it on one side. To do this, first subtract bx from both sides. The right side cancels:

Remove the -ab from the left. Add ab to both sides. The left side cancels:

Now, distribute out the x from the left side:

Divide both sides by (a-b). The left side cancels:

Therefore:

Answer:
V = 21145.01 mm³
Step-by-step explanation:
Given that:
The radius of the gumball = 30 mm
The radius of the spherical hollow-core = 28 mm
Consider the radius of the gumball to be
and the radius of the spherical hollow-core to be
. Then;
The volume of the gumball can be determined by using the formula of a sphere.


V = 21145.01 mm³
Answer:
reflex angle
Step-by-step explanation:
Acute is less than 90
Right = 90
Obtuse is greater than 90 and less than 180
Straight is 180
Reflex is greater than 180 and less than 360
This is greater than 90 and less than 180 so it is a reflex angle
