What's 0.46% of 80 equal to ?

Answers

'is' in mathematics means equal
'of' in mathematics means multiplication

0.46% can also be written as 0.46/100

$x = (0.46)/(100) * 80\n\nx = (0.46)/(10) * 8\n\nx = 0.046 * 8\n\n\boxed{\bf{x = 0.368}}$

0.46% of 80 is equal to 0.368

Convert percentage into decimal: 0.46%/100 = 0.0046

Multiply the decimal by 80: 0.0046 × 80 = 0.368 <-- our answer.

The endpoints of the diameter of a circle are (-7,3) and (5,1) . What is the center of the circle

Answers

Answer:

The center is the point $(-1,2)$

Step-by-step explanation:

we know that

The center of the circle is equal to the midpoint of the endpoints of the diameter

The formula to calculate the midpoint between two points is equal to

$M((x1+x2)/(2),(y1+y2)/(2))$

substitute the values

$M((-7+5)/(2),(3+1)/(2))$

$M((-2)/(2),(4)/(2))$

$M(-1,2)$

therefore

The center is the point $(-1,2)$

NEED ANSWER AS SOON AS POSSIBLE

Answers

So, as you should know the volume of a cylinder is ( pi x r^2 x h ) and since it has a diameter and not the radius you would cut it in half therefore the radius is 4. 8/2=4 4*4= 16 16*14=224 224*3.14= 703.36 So, therefore your answer would be A. Hope this helps!
