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

Answer:

C. 1458 cubic units

Step-by-step explanation:

one cubes side length is 9. The only side that changes is the length since the size is doubled so instead of it 9 it would be 18.

V= L × W × H

= 18 × 9 × 9

= 1,458

hope this helped youuu

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.

Answer:

y = 1.37

Step-by-step explanation:

30y = 41.10

divide both sides of the equation by 30

30y/30 = 41.10/30

y = 41.10/30

y = 1.37

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

Answer:

x = -4

Step-by-step explanation:

Move all terms that don't contain  x  to the right side and solve.

Answer:

The x intercept is -6.

Step-by-step explanation:

12 - 24 = 12

-3xc = 12

-3/12 = -6

x = -6.

Answer:

[0,12]

Step-by-step explanation:

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

Answer:

The length of EG is 58 units

Step-by-step explanation:

The midpoint of a segment divides it into two equal part

Let us use this rule to solve our question

∵ E, F, and G are collinear points

∵ Point F is the midpoint of segment EG

→ That means F divides EG into 2 equal segments EF and FG

∴ EF = FG

∵ EF = 5x + 9

∵ FG = 3x + 17

→ Equate them

∴ 5x + 9 = 3x + 17

→ Subtract 3x from both sides

∵ 5x - 3x + 9 = 3x - 3x + 17

∴ 2x + 9 = 17

→ Subtract 9 from both sides

∴ 2x + 9 - 9 = 17 - 9

∴ 2x = 8

→ Divide both sides by 2 to find x

∵ [tex]\frac{2x}{2}=\frac{8}{2}[/tex]

∴ x = 4

→ Substitute x by 4 in EF and FG to find their lengths

∵ EF = 5(4) + 9 = 20 + 9 = 29

∵ FG = 3(4) + 17 = 12 = 17 = 29

∵ EG = EF + FG

∴ EG = 29 + 29 = 58

∴ The length of EG is 58 units

Step-by-step explanation:

Given that :

Motorcycle driver travels 15kph faster than a bicycle rider

Motorcycle covers 60km in 2 hours less than the time it takes bicycle rider to travel the same distance ;

Let bicycle rider's speed = r kph

Motorcycle driver's speed = (15 + r) kph

TIME it takes bicycle rider to cover a distance of 60km = t hours

TIME it takes motorcycle driver to cover a distance of 60km = (t - 2) hours
