Determine the mass of a solid steel ball that has a diameter of 10 cm. The density of pure steel is 8.09 g/cm3
Answer:
The mass of the steel ball is 4,235.9 gr
Step-by-step explanation:
Density
The density ρ of a substance is a measure of its mass per unit volume:
[tex]\displaystyle \rho=\frac{m}{V}[/tex]
If the density and the volume are given, the mass can be calculated by solving the above formula for m:
[tex]m=\rho.V[/tex]
We know the density of pure steel ρ=8.09 gr/cm3 and the diameter of a solid steel ball d=10 cm.
We need to calculate the volume of the sphere:
The volume of a sphere of radius r is given by:
[tex]\displaystyle V=\frac{4}{3}\cdot \pi\cdot r^3[/tex]
The radius is half the diameter: r= 10/2 = 5 cm. Thus:
[tex]\displaystyle V=\frac{4}{3}\cdot \pi\cdot 5^3[/tex]
Calculating:
[tex]V=523.6\ cm^3[/tex]
The mass is:
[tex]m=8.09 gr/cm^3 \cdot 523.6\ cm^3[/tex]
m=4,235.9 gr
The mass of the steel ball is 4,235.9 gr

Tony wants to build a fence around his rectangular garden that has
dimensions 20 ft by 35 ft. His fence posts need to be placed 5 ft apart.
How many posts will Tony need to buy?
posts
Answer:
22
Step-by-step explanation:
The side of the rectangle that is 20 feet divide it by 5
[tex]\dfrac{20}{5}=4[/tex]
Now we add one to this as the fence post each required in each 5 feet section.
The same is the case for the opposite side.
So, the number of fence posts for the 20 feet sides is [tex]5+5=10[/tex]
Now for the 35 feet side
[tex]\dfrac{35}{5}=7[/tex]
Remove 1 fence post from the ends as that fence post will be covered by the ones on the 20 feet side.
So, new posts on the 35 ft side is 6.
So, the number of fence posts for the 20 feet sides is [tex]6+6=12[/tex]
Total number of posts is [tex]10+12=22[/tex]
Meg has a can that contains 80% orange juice and the rest water. The can has 1 liter of water.
Part A: Write an equation using one variable that can be used to find the total number of liters of orange juice and water in the can. Define the variable used in the equation. (5 points)
Part B: How many liters of orange juice are present in the can? Show your work. (5 points)
help
Answer:
1w+4o=5
Step-by-step explanation:
w=water o=orange juice there is 4 liters of orange juice
Answer:
80% juice : 20% water
x : 1 liter
80 ÷ 20 = 4
1 liter x 4 = 4 liter
x = 4
Part a = x÷4 or x/4
Part b = 4 liter

Emily works at a fast food outlet. Every week she splits her wages between savings and spending money in the ratio of 2:7 Last week she earned £144. What was Emily’s split between savings and spending money?
Answer:
His savings be $32 and spendings be $112.
Step-by-step explanation:
Let her savings and spending be 2x and 7x.
Total earning is equal to the sum of savings and spending.
ATQ,
2x+7x=144
9x=144
x = 16
Savings = 2x = 2(16) = $32
Spendings = 7x = 7(16) = $112
Hence, his savings be $32 and spendings be $112.
is 0.012 less then 0.12 or greater then
Answer: Greater than
Step-by-step explanation: 0.012 is 12 hundreths
0.12 is 12 tenths
Write an equation through the point (4,8) that is parallel to y=5x-9
Answer:
Y=5x - 12
Step-by-step explanation:
Take a point as (x,y) on the (4,8) line,
The slope of equation is 5,
[tex] \frac{y - 8}{x - 4} = 5[/tex]
Y-8 =5x-20
Y= 5x - 12

Derek wants to order some roses online. Florist A charges $4.75 per blue
rose plus $40 delivery charge. Florist B charges $5.15 per red rose plus $25
delivery charge. If Florist B increases the cost per rose to $5.20, for what
number of roses is it less expensive to order from Florist A? From Florist B?
Step-by-step explanation:
let the total charge be y
and the number of rose be x
Florist A charges
y=40+4.75x---------1
Florist B charges
y=25+5.2x--------2
to solve for the number of roses we need to equate 1 and 2
40+4.75x=25+5.2x
40-25=5.2x-4.75x
15=0.45x
x=15/0.45
x=33.33
The number of roses that will be less expensive to order from A is 33.33
Answer:
Step-by-step explanation:
33.33

Why are unit prices important?
Unit price matters because retailers and manufacturers have different sized packages, such as regular and family-sized cereal. Looking at the unit price gives you a consistent tool by which to determine which package is cheaper—although discounts often happen with larger amounts, bigger doesn't always mean you'll save.

i’m not sure what the answer is to
-40 = 10 – 10s
Answer:
s = 5
Step-by-step explanation:
-40 = 10 - 10s
-10 -10
-50 = -10s
/-10 /-10
s = 5
Answer:
s=5
Step-by-step explanation:
Well first, to isolate x, we need to subtract 10 on both sides.
-40=10-10s
-10 -10
-50=-10s
Now, we can divide 10 on both sides to solve for s.
-50=-10s
/-10 /-10
5=s
