Answer 1

Answer:

x = 12

Step-by-step explanation:

An exterior angle of a triangle is equal to the sum of its opposite interior angles in a triangle

∠CBV is an exterior angle and ∠BCD and ∠CDB are ∠CBV's opposite interior angles

This means that ∠BCD + ∠CDB = ∠CBV

If we are given that ∠CBV = 9x - 3, ∠BCD = 5x + 15 and ∠CDB = 30

Then 9x - 3 = 5x + 15 + 30

                    ^ (Note that we just created an equation we can use to solve

                        for x )

We then use the equation we created to solve for x

9x - 3 = 5x + 15 + 30

step 1 combine like terms

30 + 15 = 45

we now have 9x - 3  = 5x + 45

step 2 add 3 to each side

-3 + 3 cancels out

45 + 3 = 48

we now have 9x = 5x + 48

step 3 subtract 5x from each side

9x - 5x = 4x

5x - 5x cancels out

we now have 4x = 48

step 4 divide each side by 4

48 / 4 = 12

4x / 4 = x

we're left with x = 12

Answer 2

Answer:

30+5x+15=9x-3

9x-5x =45+3

4x=48

x =12

What is the radius of this circle of the circumference is 18pi cm?

Answers

Answer:

r=9cm

Step-by-step explanation:

C= 2pi r = 18 pi so

2r =18 so r = 18/2=9

Answer:

[tex]r=9[/tex]

Step-by-step explanation:

The equation to find the circumference of a circle when given the radius is the following,

[tex]C=r(\pi)(r)[/tex]

There (C) represents the circumference, (r) represents the radius, and ([tex]\pi[/tex]) represents the irrational numbers (3.1415...)

Substitute in the given values and backsolve for the radius,

[tex]18(\pi)=2(\pi)(r)[/tex]

Inverse operations,

[tex]18(\pi)=2(\pi)(r)[/tex]

[tex]9=r[/tex]

Answers

The answer is d 48 I just took the test

The interquartile range(IQR) of the recorded weight of ken is calculated as 17 pounds.

What is the interquartile range of a data?

The interquartile range(IQR) = third quartile(Q3) - first quartile(Q1)

The third quartile of in the box plot given is : 56 pounds

The third quartile of the data as represented in the box plot given :

Find the volume of a pyramid with a square base, where the perimeter of the base is
9.9 cm and the height of the pyramid is 8.6 cm. Round your answer to the nearest
tenth of a cubic centimeter.

Answers

The volume of a pyramid with a square base is 17.6 cubic centimeter.

Given the following data;

Perimeter of base = 9.9 cmHeight of pyramid = 8.6 cm

To find the volume of a pyramid with a square base;

Mathematically, the volume of a pyramid with a square base is given by the formula;

[tex]V = A(\frac{h}{3})[/tex]

Where;

V is the volume of a pyramid with a square baseA is the area of the square base.h is the height of the pyramid.

First of all, we would determine the length of sides of the square base from its perimeter;

[tex]Perimeter \ of \ square = 4s\\\\9.9 = 4s\\\\s = \frac{9.9}{4}[/tex]

s = 2.475 cm

Next, we would determine the area of the square;

[tex]Area \ of \ a\ square = s^{2} \\\\Area \ of \ a\ square = 2.475^{2}[/tex]

Area of a square = 6.126 cm

Now, we would use the above value to find the volume of a pyramid with a square base.

Substituting the values into the formula, we have;

[tex]V = 6.126*(\frac{8.6}{3})\\\\V = 6.126*2.867[/tex]

Volume, V = 17.6 cubic centimeter

Therefore, the volume of a pyramid with a square base is 17.6 cubic centimeter

After 4 years eldi will be three times the age he had 10 years ago. Using algebra find the age of eldi

Answers

Suppose that Eldi has x years old now :

x + 4 = 3 × ( x - 10 )

x + 4 = 3x - 30

Add both sides 30

x + 4 + 30 = 3x - 30 + 30

x + 34 = 3x

Subtract both sides x

x - x + 34 = 3x - x

34 = 2x

2x = 34

Divide both sides by 2

2x ÷ 2 =34 ÷ 2

x = 17

_____________________________

Thus Eldi is 17 .

Answers

Answer: what’s the answer ?

Step-by-step explanation:

If each cylinder is 4 feet tall and has a diameter of 1 foot then the amount of sand needed to fill the cylinders is 19 cubic feet.

Given that there are 6 cylindrical posts protecting the equipment

To find tge amount of sand needed for cylinders,

We need to find the volume of each cylinder.

The cylinder is 4 feet tall and has a diameter of 1 foot,

Height is 4 feet

Diameter is 1 foot and radius is 1/2 feet.

Volume of cylinder = πr²h

=3.14×(1/4)(4)

=3.142 cubic feet.

As there are six cylinders.

Multiply 6 with 3.142

Amount of sand needed = 6×3.142

= 18.852 cubic feet.

A radio station broadcasts a signal over an area with a 120-mile diameter. The population density of the area is 100 people per square mile.

How many people are within receiving distance of the broadcast signal?

Use 3.14 for pi.

Answers

Answer:

1,130,400 people

Step-by-step explanation:

Find the area of the broadcasting area, using the circle area formula.

Since the diameter is 120 miles, the radius will be 60 miles.

Use the circle area formula, plug in 60 as r, and plug in 3.14 as pi:

A = [tex]\pi[/tex]r²

A = (3.14)(60²)

A = 11304

So, the area is 11304 square miles

To find how many people are in receiving distance, multiply this by 100, since there are 100 people per square mile.

11304(100)

= 1,130,400

So, 1,130,400 people are within receiving distance of the signal.

Answer:

1,130,400

Answers

1 hour is 60 minutes
Therefore, 1/8 of 60 is 7.5, meaning, 1 litre of water is leaked every 7.5 minutes.
3¾ hours is 60 x 3 + 60/4
= 180 + 15
= 195 minutes
As 3 ¾ hours is 195 minutes and 1 litre is leaked every 7.5 minutes, we have to divide 195 by 7.5.
195/7.5 = 26

Therefore, the garden hose will leak 26 litres in 3 ¾ hours.
