A golf ball has a diameter of 42.67 millimeters and a mass of 45.93 grams.what is the number of grams per cubic millimeter of the material used to make the golf ball?
The density of golf ball is 0.000113 gm/mm³
What is volume ?
Volume is a three dimensional space occupy by the body of particular shape such as here :
volume (V) of sphere with radius r : 4πr³/3
it is given that :
golf ball has a diameter d of = 42.67 millimeters
r = d/2 = 21.33 mm
golf ball has a mass m of = 45.93 grams
First, let us find the volume of the golf ball can be determined using the formula:
V = 4πr³/3
Substituting r = 21.33mm, we get;
V = 4π(21.33)³/3
V = 40650 mm³
Now, to find the number of grams per cubic millimeter of the material used to make the golf ball we find the density of golf ball :
ρ = m/V
ρ = 45.93/40650
ρ = 0.000113 gm/mm³
Therefore, the density of golf ball is 0.000113 gm/mm³

Answer:
C, which is 340!
Step-by-step explanation:
Split the polygon into two rectangles to make it easier (see the attachment below), and calculate the areas of both rectangles. Then add the areas of the two rectangles, 264+76=340. So the answer is 340 square units, or C. Hope this helped!! :)
The area of polygon = 340 square units.
How to estimate the area of the polygon?Area of rectangle = Length [tex]\times[/tex] [tex]\tmes[/tex]breadth
Area of rectangle (side A) = 19 [tex]\times[/tex] 4 = 76
Area of rectangle (Side B) = 24 [tex]\times[/tex] 14 = 264
To estimate the area of the polygon, add both of the equations then we get
Area of the polygon
= Area of a rectangle (side A) + Area of a rectangle (Side B)
= 76 + 264
Area of the polygon = 340 square units.
Therefore, the correct answer is option C. 340 square units.

how much work is done when you lift an object that weighs 150 N to a height of 5 meters
Answer:
Work done = 150 x 5 = 750 J
Step-by-step explanation:
Work done is the measure of energy transferred to an object when a force is added causing the object to move a distance in the direction of the force.
The equation for work done is force time the distance and is measured in Joules. Therefore the formula is W = F x D
work done (W) is measured in joules (J)
force (F) is measured in newtons (N)
distance (d) is in the same direction as the force and is measured in
metres (m)
W = F x D
w = 150 x 5
W = 750 J

What is the equation of a circle with center (-4, 7) and radius 6?
Answer:
(x +4)^2 + (y-7)^2 = 36
Step-by-step explanation:
The equation of a circle is of the form
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x- -4)^2 + (y-7)^2 = 6^2
(x +4)^2 + (y-7)^2 = 36
Solve for y.

Y=
Answer:
y=2
Step-by-step explanation:
3 = (y+7)/3
Multiply each side by 3
3*3 = (y+7)/3 *3
3*3 = y+7
9 = y+7
Subtract 7 from each side
9-7 = y+7-7
2 =y
Answer:
2 = y
Step-by-step explanation:
3 = y + 7 ÷ 3
multiply both side of equation by 3
3 × 3 = y + 7 ÷ 3 / 3
9 = y + 7
subtract 7 from both side
9 - 7 = y + 7 - 7

6. Find JL.
Please and thank you. 5x-16=3x+4
Answer:
JL = 68
Step-by-step explanation:
JM = ML
Hence, 3x + 4 = 5x - 16
Subtract 3x from both sides
4 = 2x - 16
Add 16 to both sides
20 = 2x
Divide both sides by 2
10 = x
Now we want to find JL
Note that JL = JM + ML
JM = 3x + 4 and x = 10
Substitute 10 for x
3(10) + 4
Multiply
30 + 4
Add
JM = 34
Because JM = ML
We simply multiply 34 times 2 to find the length of JL
34 * 2 = 68
JL = 68

Step-by-step explanation:
Hello!
To find f(-7) you simply plug the value, -7, into the function.
This will get you:
f(-7) = 4(-7)^2 - 4(-7)
Remember that the square of a negative number is a positive! Also, remember to use the order of operations (PEMDAS)!
This will get you:
f(-7) = 4(49) - 4(-7)
f(-7) = 196 - (-28)
f(-7) = 224

increase amount = $70 - $40
=$30
increase percent = increase amount /original amount *100%
=30/40 *100%
=3000/40
=75%
to find decrease percent

find the gradient and y intercept of 3x+4y=5
Answer:
gradient = - [tex]\frac{3}{4}[/tex] , y- intercept = [tex]\frac{5}{4}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + 4y = 5 ( subtract 3x from both sides )
4y = - 3x + 5 ( divide terms by 4 )
y = - [tex]\frac{3}{4}[/tex] x + [tex]\frac{5}{4}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{3}{4}[/tex] and y- intercept c = [tex]\frac{5}{4}[/tex]
