Answer:

5/37.

Step-by-step explanation:

Sum:

3/4 + -4/7

= 21/28 - 16/28

= 5/28

Difference:

3/4 -  (-4/7)

= 3/4 + 4/7

= 21/28 + 16/28

= 37/28.

Dividing:

5/28 / 37/28

= 5/28 * 28/37

= 5/37.

Answer:

{(-2, -3), (-3, -2), (2,3), (3, 2)}

Step-by-step explanation:

A function is a set of ordered pairs in which no two pairs have the same first number.

In other words, an x cannot be paired with two y's.

A function takes an x and pairs it with one and only one y.

{(0,0), (0, 2), (2.0), (2, 2)} is not a function because it pairs 0 with both 0 and 2.

{(2,-1), (2, 1), (3,-1), (3, 1)} is not a function because it pairs 2 with both -1 and 1.

{(2, 2), (2, 3), (3, 2), (3, 3)} is not a function because it pairs 2 with both 2 and 3.

Answer:

Height of the cuboid= 2.5 cm

Step-by-step explanation:

Volume of a cuboid = length× width ×height

=> 100=8×5× h

=

[tex]h = \frac{100}{8 \times 5} [/tex]

[tex]h = 2.5[/tex]

height of the cuboid= 2.5 cm

Step-by-step explanation:

The height of a cylinder is twice the radius of its base.

Let the height of the cylinder = 2x

Let the radius of the cylinder = x

By formula, volume of the cylinder = π[tex]r^{2}[/tex] h

here r = x, h = 2x

substituting the values in the equation, we get

volume of the cylinder = π[tex]r^{2}[/tex] h =  π [tex]x^{2}[/tex] (2x)

volume of the cylinder = 2π[tex]x^{3}[/tex]

The expression that represents the volume of the cylinder is 2x³π.

A cylinder is a three-dimensional object that is made up of a two circles that are attached to a rectangle.

Volume of a cylinder = πr²h

2xπx² = 2x³π.

Usually pounds (lb) .About an an average of  20 to 25 pounds (lbs)

Step-by-step explanation:

Since Marvin uses Customary units, and considering the Watermelon.

Pounds,  He could estimate based on average of 20 to 25 pounds.

He could choose another customary units, but it wouldn't be practical and unusual to say a watermelon of 160 quarters, also it would leave all the listeners without parameters.

So, definitely pounds.

Answer:

37

Step-by-step explanation:

To find the side length in the middle is 12. This is because A(12) squared + B(5) squared = C(13) squared.

Now that we know the side length, we can find x. A(35) squared + B(12) squared = C(x) squared.

35*35=1225.

12*12=144.

1225+144=1369

The root of 1369 is 37, so the value of x is 37.

Okay, we are going to solve this backwards!

First, we need to know that the formula for circumference is

c = π × d

d = diameter

π = 3.14

They told us what the circumference is, so let's plug it in

75 = (3.14) × (d)

let's solve for d

[tex]\frac{75}{3.14} = d[/tex]

d = 23.88 inches

We must remeber that the radius is HALF of the diameter, so let's divide the diameter by 2

[tex]\frac{23.88}{2} = 11.94[/tex]

Now, let's round to the nearest whole inch like they suggested

11.94 ≈ 12

The answer is 12 inches!

Answer: "distance from zero on a number line"

Explanation: Absolute value means "distance from zero" on a number line.

Since distance can either be 0 or positive,

absolute value is either 0 or positive.

Absolute value is represented with vertical bars on either side of the number.

An example is shown below, we have the absolute value of -5.

The absolute value of a number is just

the positive version of that number.

So the positive version of -5 is 5.

[tex]\pi (5^{2})(13)+\frac{1}{3} \pi (5^{2})(12)[/tex]

The expression that represents the volume of the composite figure is Pi(5^2)(13) + One-third pi (5^2)(12).

The volume of the composite figure is the sum of the volume of the cone and the volume of the cylinder.

A cone is stacked on top of a cylinder.

They both share a circular base.

The total height of the composite figure is 25.

The height of the cylinder is 13 and the radius is 5.

The expression represents the volume, in cubic units, of the composite figure;

The volume of a cylinder = πr²h

π = 22/7

r = radius = 5

h = height = 13

The volume of a cylinder = π(5²)(13)

The volume of a cone = 1/3(πr²h)

π = 22/7

r = radius

h = height = 25 - 13 = 12

The volume of a cone = (1/3)(π(5²)(12)

The expression represents the volume, in cubic units, of the composite figure is;

= Pi(5^2)(13) + One-third pi (5^2)(12).

Hence, the expression that represents the volume of the composite figure is Pi(5^2)(13) + One-third pi (5^2)(12).

Answer:

The length of the arc is 2.25 units.

Step-by-step explanation:

The circumference of a circle is [tex]2\pi r[/tex], where r is radius of the circle.

Total angle of a circle in degree is 360°.

Length of central angle formula

[tex]\textrm{Arc length}=\frac{2\pi r}{360^\circ}\times \textrm{central angle degree}[/tex]

[tex]\Rightarrow \textrm{Arc length}=\frac{\textrm{circumference}}{360^\circ}\times \textrm{central angle degree}[/tex]

Given that,

A circle has a circumference of 5 units.An arc in the circle has a central angle of 162°.

Then,

[tex]\textrm{Arc length}=\frac{\textrm{circumference}}{360^\circ}\times \textrm{central angle degree}[/tex]

[tex]\textrm{Arc length}=\frac{5}{360^\circ}\times162^\circ[/tex]

                 [tex]=\frac{810}{360}[/tex]

                 [tex]=\frac{9}{4}[/tex]

y = 6|x|

Given:

The diameter of the circle P is 30 cm.

The radius of the circle P is 15 cm.

The measure of ∠RPS is 125°

We need to determine the arc length of QR.

Measure of ∠QPR:

The angles QPR and RPS are linear pairs.

Thus, we have;

[tex]\angle QPR + \angle RPS=180^{\circ}[/tex]

Substituting the values, we have;

[tex]\angle QPR + 125^{\circ}=180^{\circ}[/tex]

          [tex]\angle QPR =55^{\circ}[/tex]

Thus, the measure of ∠QPR is 55°

Arc length of QR:

The arc length of QR can be determined using the formula,

[tex]Arc \ length =(\frac{\theta}{360})2 \pi r[/tex]

Substituting [tex]\theta=55[/tex] and r =15, we get;

[tex]Arc \ length =(\frac{55}{360})2 (3.14)(15)[/tex]

[tex]Arc\ length = \frac{5181}{360}[/tex]

[tex]Arc \ length =14.4 \ cm[/tex]

Thus, the arc length of QR is 14.4 cm.

Hence, Option d is the correct answer.
