Salma's company makes solid metal balls for various industrial uses. A customer wants lead balls that have a diameter of 6 in. If Salma must make 80 of these balls, how much lead will she need?
HEELPP ME PLLEASEE
Answer:
Total volume of 80 balls = 2,263.2 inch³
Step-by-step explanation:
Given:
Diameter of lead ball = 6 inch
Number of ball need = 80
Find:
Total volume of 80 balls
Computation:
Radius of lead ball = Diameter / 2
Radius of lead ball = 6 / 2
Radius of lead ball = 3 inch
Volume of lead ball = πr²
Volume of lead ball = (22/7)(3)²
Volume of lead ball = (22/7)(9)
Volume of lead ball = 28.29 inch³ (Approx.)
Total volume of 80 balls = 80 x Volume of lead ball
Total volume of 80 balls = 80 x 28.29
Total volume of 80 balls = 2,263.2 inch³
Find the midpoint of the line segment joining points A and B. A(2,-7); B(2,3) The midpoint of the line segment is (Type an ordered pair.)
The midpoint of a line segment is the point that is exactly halfway between the two endpoints. To find the midpoint of the line segment joining points A(2,-7) and B(2,3), we can use the midpoint formula:
Midpoint = [(x1 + x2) / 2, (y1 + y2) / 2]
where (x1, y1) and (x2, y2) are the coordinates of the two endpoints.
Substituting the values for A and B, we get:
Midpoint = [(2 + 2) / 2, (-7 + 3) / 2]
Midpoint = [4 / 2, -4 / 2]
Midpoint = [2, -2]
Therefore, the midpoint of the line segment joining points A and B is (2, -2).

all answer options.
The equation of the line passing through two points (0, 0) and (4, -2) is y = -x/2
What is an equation of the line?The general equation of a line in two variables of the first degree is represented as Ax + By +C = 0, A, B ≠ 0 where A, B and C are constants which belong to real numbers.
Given is a line passing through two points (0, 0) and (4, -2), we need to find the equation of the line,
We know that the equation of the line, passing through two points (x₁, y₁) and (x₂, y₂), is given by:
y-y₁ = y₂-y₁ / x₂-x₁ (x-x₁)
Here, (x₁, y₁) and (x₂, y₂) are (0, 0) and (4, -2), putting the values to finding the equation,
y-0 = -2-0 / 4-0 (x-0)
y = -1/2(x)
y = -x/2
Hence, the equation of the line passing through two points (0, 0) and (4, -2) is y = -x/2

Answer:
14. 53.1°
16. 253.7°
Step-by-step explanation:
14. The measure of angle L can be found from the cosine relation:
Cos = Adjacent/Hypotenuse
cos(L) = 9/15 = 3/5
L = arccos(3/5) = 53.1° . . . arc MK
__
16. Arc MK is half of arc JK, so that arc is 106.3°. The long arc JPK is the difference between 360° and the measure of the short arc JK.
360° -106.3° = 253.7° . . . arc JPK

Answer:
1/8", 1/4", 3/8", 5/8", 3/4", 12"
Step-by-step explanation:
First, make all of the fractions have similar denominators. We'll use eighths.
1/4 = 2/8
3/4 = 6/8
The rest are either whole numbers or already have a denominator of 8.
2/8, 6/8, 12, 1/8, 3/8, 5/8.
Rearrange.
1/8, 2/8, 3/8, 5/8, 6/8, 12.
Now we take the fractions we converted, and change them back to their original form. Then we'll have the answer.
1/8, 1/4, 3/8, 5/8, 3/4, 12.

What is the area in square inches of the shaded area? Use 3.14 for π and round your answer to the nearest whole number.
Answer:
Area of shaded region=2 ×3.14×R -2×3.14×r(where R is lager radius and r is smaller radius.)
Therefore area of shaded region=2×3.14×12 -2×3.14×8

Answer:

Step-by-step explanation:
Let's figure out the change in x (the 'run') and the change in y (the 'rise'). Going from the first point to the second, we see that x increases by 3 and y stays the same. Therefore we know that the line is a horizontal one with zero slope.

Help me please ASAP
Answer:
m<2 = 70degrees
m<3 = 70degrees
m<4 = 110degrees
m<5 = 110degrees
m<6 = 70degrees
m<7 = 70degrees
m<8 = 110degrees
Step-by-step explanation:
A line has the angles of 180 degrees so if m<1 is 110 then m<2 must be 70degrees. Then m<4 is opposite side of m<1 so it has to be the same number of degrees and the same for m<3 is the opposite side of m<2.

Answer:
36°
Step-by-step explanation:
From the question,
The sum of the exterior angle of a polygon = 360
From the diagram. the polygon is Decagon
Note: A Decagon is a polygon with 10 sides.
number of sides = 10 .
The exterior angle of a regular polygon = sum of the exterior angle/number of sides.
Exterior angle = 360/10
Exterior angle = 36°
Hence the measure the single extrior angle = 36°

A glass prism on a chandelier is 80 millimeters long. A base of the prism is an equilateral triangle with side lengths of 9 millimeters and a height of about 5.8 millimeters. What is the approximate surface area of the prism?
Let's find the area of the equilateral triangle first:
There are two triangles - one on each end. So we multiply our previous expression by 2.
Each rectangle is 75 millimeters long and 9 millimeters wide: 75*9 mm^2.
We have 3 rectangles each the same size so we multiply 75*9 by 3.
75*9*3 = 2025
2025 + 70.2 = 2095.2
