What is the distance between (8, -3) and (4, -7)?

Answer: Volume of a sphere = 4/3 * pi * r^3       r = radius of sphere      pi~ 3.14

Step-by-step explanation: If you use the radius in inches, your result will be in cubic inches (in^3)

The amount of water in cubic inches, that Mya's exercise ball will hold is 904.779 in³.

The volume of a sphere is the volume of space occupied by a sphere.  It is given by the formula:

[tex]\text{Volume of Sphere} = \dfrac{4}{3}\pi r^3[/tex]

As it is given that the diameter of Mya's ball is 12 inches, also we know that the volume of a sphere is given by the formula,

[tex]\text{Volume of Sphere} = \dfrac{4}{3}\pi r^3[/tex]

As we know that the diameter of Mya's ball is 12 inches, therefore, the radius of Mya's ball can be written as,

[tex]\rm Radius = \dfrac{Diameter}{2} = \dfrac{12\ in}{2} = 6\ in.[/tex]

Now, if we substitute the value of the radius of Mya's ball in the formula of the volume of the ball,

[tex]\rm \text{Volume of Ball} = \dfrac{4}{3}\times \pi \times 6^3 = 904.779\ in^3[/tex]

Hence, the amount of water in cubic inches, that Mya's exercise ball will hold is 904.779 in³.

Answer:

-8/5 + 2x = y

Step-by-step explanation:

-8=-10x + 5y

Add 10x to each side

-8+10x=-10x+10x + 5y

-8+10x = 5y

Divide each side by 5

-8/5  + 10x/5 = 5y/5

-8/5 + 2x = y

[tex]\sf\dashrightarrow -8=-10x + 5y [/tex]

[tex]\sf\implies -8=5(2x+y)[/tex]

Answer:

H = 8 + 3t

Step-by-step explanation:

H = height

t = time in months

H = 8 + 3t

H is the height at and given time. 8 is the initial height and since it grows 3 in a month it would be 3 times how ever many months have passed.

For example after 6 months

t = 6

H = 8 + 3 (6)

H = 8 + 18

H = 26in

Answer:

Domain is the set of all x values, the independent quantity, for which the function f(x) exists or is defined.

Step-by-step explanation:

i just graphed it

Answer:

Domain:

[tex]x\in\mathbb{R}[/tex]

Range:

[tex]y\geq -5[/tex]

Step-by-step explanation:

The domain is the span of x-values covered by the graph, and the range is the span of y-values covered by the graph.

From the graph, we can see that the x-values covered by the graph will extend infinitely in both directions. Therefore, the domain of the graph is all real numbers.

We can't write this as an inequality, but we can write:

[tex]x\in\mathbb{R}[/tex]

For the range, we can see from the graph that the lowest y-value is y=-5. The graph doesn't go any lower than that. However, the graph will also cover all values greater than -5. Therefore, the range of the graph is all values greater than or equal to -5. In an inequality, this is:

[tex]y\geq -5[/tex]

3 of the 6 sides that exist on a dice have odd numbers.

Answer:

1/2 probability of getting an odd number

Step-by-step explanation:

Dice have the given outcomes of getting a 1, 2, 3, 4, 5, or 6. Considering that the desired outcomes are only 3 out of 6 of those given outcomes, that leaves us with a 3/6 or 1/2 chance of getting an odd number.

Answer:

Step-by-step explanation:

subtracted it with a scientific calculator and that was the answer

To find the cost of planting grass , we have to find area of the field.

Area of field = Length × Breadth

[tex]{= 300×170}[/tex]

[tex]{=51000 sq. m}[/tex]

Now convert into hectare.

1 hectare = 10000m sq.

51000 / 10000

So area field = 5.1 hectare sq.

Now cost = 5.1 x 0.80 p

Answer:

C

Step-by-step explanation:

the statement (y<1/2x -4) reads "y is LESS than 1/2 x -4."

to fulfil this statement, follow these steps.

1) graph the line 1/2x -4, there will be a yintercept at (0,-4). Also the slope will be increasing (left to right) because 1/2 has no negative sign before it.

2) recognize the inequality sign. In this situation, the solution does NOT INCLUDE THE LINE, rather it includes the area BELOW/LESS THAN the line. If this, < had a line under it, it would mean less than OR equal to.

3) know that if the line is not included, the line will be broken. If the line IS included, which it is not, it would be a solid line.

Answer:

C

Step-by-step explanation:

First, graph the equation:

The y-intercept is -4.

And the slope is 1/2, an upward sloping line.

So, our graph should be either A, B, or C.

D is not correct, so eliminate that.

So, our inequality is:

[tex]y<\frac{1}{2}x-4[/tex]

Note that this inequality is strictly less than. There's no "or equal to" bar. Therefore, our line should be dotted.

Thus, eliminate A and B.

So, C is our answer

Further notes:

The inequality sign means that y is less than the equation. In other words, our shaded region should be below the line.

In C, the shaded area is indeed below the line.

So, C is indeed our answer :)

Answer:

The rate of the plane is 753 km/h while the rate of the wind is 75km/h

Step-by-step explanation:

Here in this question, we are interested in calculating the rate of the plane in still air and the rate of the wind.

Since we do not know these rates, we shall be representing both using variables.

Let’s represent the rate of the plane in still air by x kmph while the rate of the wind be represented by y kmph

Now, for us to calculate the speed of the plane while it travels against the wind, that would be the speed of the plane in still air minus the speed of the wind.

Mathematically, that would be (x-y) kmph

Now the speed of the plane while it travels with the wind would be its speed in still air plus the speed of the wind.

Mathematically, that would be;

(x + y) kmph

From the question;

The plane journeyed 5424 km against the speed in 8 hours, this means that its speed will be 5424/8 = 678 kmph

Thus, that means;

x -y = 678 •••••••(i)

Now, traveling with the wind , its speed will be ;

6624/8 = 828 kmph

Thus;

x + y = 828 kmph •••••••(ii)

So we have two equations to solve simultaneously;

Let’s add both together;

x -y + x + y = 828+ 678

2x = 1,506

x = 1506/2

x = 753 kmph

From ii

x + y = 828

y = 828 - x

y = 828 - 753

y = 75 kmph

Yes

Answer:

$9600.72

Step-by-step explanation:

Area of the field = length × width

Length = 1,021 feet

Width= 725 feet

Area of the field = length × width

= 1,021 feet × 725 feet

= 740,225 square feet

One bag covers 1000 square feet

There are 740,225 square feet

Find the number of bags that will cover the total of 740,225 square feet

Total bags = 740,225 / 10000

=740.225 bags

A bag cost $12.97

Total cost of 740.225 bags= 740.225 × 12.97

= $9600. 71825

Approximately

$9600.72

1101₂ + 1110₂ + 1001₂ = 100100₂

1101₂ = 1×2³ + 1×2² + 0×2¹ + 1×2⁰ = 8 + 4 + 0 + 1 = 13₁₀

1110₂ = 1×2³  + 1×2² + 1×2¹ + 0×2⁰ = 8 +  4 + 2 =  14₁₀

1001₂ = 1×2³ + 0×2² + 0×2¹ + 1×2⁰ = 8 + 1 = 9₁₀

13 + 14 + 9 = 36

36₁₀ =

36 : 2 = 18 + r 0

18 : 2 = 9 + r 0

9 : 2 = 4 + r 1

4 : 2 = 2 + r 0

2 : 2 = 1 + r 0

1 : 2 = 0 + r 1  ↑

= 100100₂
