Answer:
430.5
Step-by-step explanation:
1. We assume, that the number 525 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 525 is 100%, so we can write it down as 525=100%.
4. We know, that x is 82% of the output value, so we can write it down as x=82%.
5. Now we have two simple equations:
1) 525=100%
2) x=82%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
525/x=100%/82%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 82% of 525
525/x=100/82
(525/x)*x=(100/82)*x - we multiply both sides of the equation by x
525=1.219512195122*x - we divide both sides of the equation by (1.219512195122) to get x
525/1.219512195122=x
430.5=x
x=430.5
now we have:
82% of 525=430.5
Answer:
Step-by-step explanation:
Use the point-slope formula.
y - y_1 = m(x - x_1) you have : x_1 =1 and y_1 =2
m the slope m= -2 (same slope for the line : 2x+y-1=0 because this lines are parallel and you can write y=-2x-1
an equation for this line is : y-2 = -2(x-1)
Answer:
33,493.3 cm³
Step-by-step explanation:
Volume of a sphere of radius r = V = (4/3)πr³
Here the radius is 20 cm. Therefore, V = (4/3)(3.14)(20 cm)³ = 33,493.3 cm³
The volume of this sphere, to the nearest tenth, is 33,493.3 cm³

Answer:
First angle = 50, second angle = 26 and the third angle = 104 degrees.
Largest angle is 104 degrees.
Step-by-step explanation:
Let the second angle be x degrees, the the first will be x + 24 and the third is
4x degrees.
x + x+ 24 + 4x = 180
6x = 180 - 24
6x = 156
x = 26
so the other 2 angles are 26 + 24 = 50 and 4*26 = 104 degrees.
