Answer:
A
Step-by-step explanation:
To find the answer all you have to do is multiply each of the percentages by 3000.
57% clay
.57 × 3000 = 1,710 lb
39% silt
.39 × 3000 = 1,170 lb
4% sand
.04 × 3000 = 120 lb
Check your answer by adding the weights together. They should add up to 3000.
1710 + 1170 + 120 = 3000
It checks!
12.5 times 4. That is what you do
Answer:
Gregoire is correct; the diameter is a chord that passes through the center of the sphere.
Step-by-step explanation:
A sphere is a geometrical shape formed from a circle. Some of its parts are: diameter, center, radius circumference, etc.
The center of a sphere is a point at its middle. The diameter is a straight line, e.g a chord, that is drawn from one point on the circumference of a sphere to another point and passes through its center. While radius is a line that is from the center of the sphere to a point on its circumference.
A diameter is twice of a radius, so that:
Radius =
⇒ Diameter = 2 × Radius
Therefore with respect to the question, Gregoire is correct because a diameter is a chord that passes through the center of the sphere.
I am pretty sure it is 162. I hope this helped
