Answer:

[tex]\boxed{V = 1436.8 cm^3}[/tex]

Step-by-step explanation:

Volume of sphere = [tex]\frac{4}{3} \pi r^3[/tex]

Where r = 7 cm

Volume of Sphere = [tex]\frac{4}{3} (3.14)(7)^3[/tex]

V = [tex]\frac{4}{3} (3.14)(343)[/tex]

V = 4310/3

V = 1436.8 cm³

Answer:

Solution,

Radius= 7 cm

Volume of sphere:

[tex] \frac{4}{3} \pi \: {r}^{3} \\ = \frac{4}{3} \times 3.14 \times {7}^{3} \\ = \frac{4}{3} \times 3.14 \times 343 \\ = 1436.8 \: {cm}^{3} [/tex]

Answer:

x = 2

Step-by-step explanation:

2x - 3 = 9 - 4x

2x + 4x - 3 = 9

2x + 4x = 9 + 3

6x = 9 + 3

6x = 12

x = 2

Hope this helped! :)

Answer:

2

Step-by-step explanation:

You start of with the equation 2x-3 = 9-4x

Then you bring -4x to the left side, making it 6x-3 = 9

Take the -3 to the right, 6x = 12

Lastly divide 12 by 6

Answer: 0.20

Step-by-step explanation:

As per given :

P(student enrolled in a math class ) = 65% = 0.65

P( student enrolled in a science class) = 43%= 0.43

P( student enrolled in both ) = 13% = 0.13

Formula of conditional probability :

[tex]P(A|B)=\dfrac{P(A\text{ and }B)}{P(B)}[/tex]

Using the above formula,

The probability that the student is enrolled in a science class given that he is enrolled in maths class :

[tex]P(\text{science}|\text{math})=\dfrac{P(\text{science and maths})}{P(\text{math})}\\\\=\dfrac{0.13}{0.65}\\\\=\dfrac{13}{65}\\\\=\dfrac{1}{5}=0.20[/tex]

Hence, the probability that the student is also enrolled in a science class =  0.20 .

Answer:

EH = 3.31

Step-by-step explanation:

We have been given a right angle triangle EKL. As KH has been given as the altitude (perpendicular) of the right angled triangle, and K is the right angle, we can say that EK is tthe base of the triangle and EH is the only side lleft, which is the hypotenuse of the triangle.

Where,

EK = Base = 3

KH = perpendicular altitude

EH = Hypotenuse

m<K = 90

m<E = 25

We know that

cosθ = Base/ Hypotenuse

cos 25 = 3/ EH

EH = 3/cos25

EH = 3.31

Perpendicular alitutude can also be calculated by using the formula for tanθ.

Answer:

A decrease of 9.2% is 1 - 0.092 = 0.908. 0.908 * 721.45 = 655.08.

Answer:

721.45 x 9.2% = 721.45 x 0.092 = 66.37

so 66.37 is the discount

721.45 - 66.37 = 655.08

So 655.08 is the discounted price

655.08 is the answer

Answer:

[tex]y = 20.7[/tex]

Step-by-step explanation:

Given

The figure above

Required

Calculate the y component

Represent the y component with y, the resultant vector with s and the angle with [tex]\theta[/tex]

The y component of a vector (as it is, in this case) is calculated as thus;

[tex]sin\theta = \frac{y}{s}[/tex]

[tex]Where\ \theta = 15\\ s = 80[/tex]

Substituting these values in the equation

[tex]sin\theta = \frac{y}{s}[/tex] becomes

[tex]sin\ 15= \frac{y}{80}[/tex]

Multiply both sides by 80

[tex]80 * sin\ 15= \frac{y}{80} * 80[/tex]

[tex]80 * sin\ 15= y[/tex]

[tex]80 * 0.2588190451= y[/tex]

[tex]20.705523608 = y[/tex]

[tex]y = 20.705523608[/tex]

[tex]y = 20.7[/tex] (Approximated)

The table to represent a linear function with a rate of change of +5

So, m = 13 + 5 = 18

a = 18

The slope-intercept pattern of the linear function equation. As a result, it is written as f(x) = mx + b, where m denotes the slope and b the line's y-intercept.

The graph in the table shows a linear function.

The linear function's general equation is written as y = ax+b, where a is the slope and b is a constant.

Finding the linear function's equation by using the first and third points from the table

at x = 3  ⇒ y = 13   and   at x = 5 ⇒ y = 23

13 = 3a+b → (1)

23 = 5a+b → (2)

solve (1) and (2) to find a and b

So,  a = 5  and b = -2

∴ y = 5x - 2

After that by substitution with x = 4 int the equation of y

∴ y = 5*4-2 = 18

m= 18

Thus, option C is correct.

#SPJ7

Answer:

13.896 kg

Step-by-step explanation:

You can find the mass of the bar by first finding the volume.

V = BH

where B = area of the base (the trapezium), and

H = height (distance trapezium between bases)

The area of a trapezium is

A = (b1 + b2)h/2

where b1 and b2 are the lengths of the bases of the trapezium (the parallel sides), and

h = the altitude of the trapezium (distance between the bases of the trapezium)

V = (b1 + b2)h/2 * H

V = (12 cm + 6 cm)(5 cm)/2 * 16 cm

V = 720 cm^3

The volume of the bar is 720 cm^3.

Now we use the density and the volume to find the mass.

density = mass/volume

mass = density * volume

mass = 19.3 g/cm^3 * 720 cm^3

mass = 13,896 g

Now we convert grams into kilograms.

1 kg = 1000 g

mass = 13,896 g * (1 kg)/(1000 g)

mass = 13.896 kg

Answer: 1.3896 kg

Answer:

y=437

Step-by-step explanation:

Move all terms not containing  y  to the right side of the equation.

Add  226  to both sides of the equation.

y/23=−207+226

Add  −207  and  226.

y/23=19

Multiply both sides of the equation by  23.

23⋅y/23=23⋅19

Simplify both sides of the equation.

Cancel the common factor of  23.

cancel out the common factors

23⋅y23=23⋅19

Rewrite the expression.

y=23⋅19

Multiply  23  by  19.

Answer: [tex](x+10)^2+119=0[/tex]

Step-by-step explanation:

For a quadratic equation, the vertex form is given by : [tex]y=a(x-h)^2+k[/tex], where (h, k) is the vertex.

The given quadratic equation: [tex]x^2 + 20x + 28 = 9[/tex]

Subtract 9 from both sides

[tex]=x^2+20x+19=0[/tex]

compare this to [tex]x^2+bx=c[/tex], and add [tex](\frac{b}{2})^2[/tex] both sides

b= 20

[tex]x^2+20+100+19=-100[/tex]   [(b/2)²=20/2=10]

[tex]\Rightarrow\ x^2+2(x)(10)+10^2+119=0[/tex]

[tex]\Rightarrow\ (x+10)^2+119=0\ \ \ [\because\ (a+b)^2=a^2+b^2+2ab][/tex]

Answer:

A) ∠9 = ∠10 = ∠11 = ∠12  = 90°

∠2 = ∠3 = ∠5 = ∠8 = 135°

∠1 = ∠4 = ∠6 = ∠7 = 45°

B) 1. ∠4 and ∠1 -> vertical angles

2. ∠7 and ∠5 -> supplementary

3. ∠9 and ∠10 -> supplementary

Step-by-step explanation:

Data

The following are vertical angles, so they are congruent:

∠1 ≅ ∠4

∠3 ≅ ∠2

∠11 ≅ ∠9

∠10 ≅ ∠12

∠7 ≅ ∠6

∠5 ≅ ∠8

From here and data, it is deduced that

∠11 ≅ ∠9 ≅ ∠10 ≅ ∠12

From the picture, the addition of them is equal to 360°, then:

∠11 + ∠9 + ∠10 + ∠12 = 360°

4*∠11 = 360°

∠11 = 360°/4

∠11 = 90° = ∠10 = ∠9 = ∠12

∠2 and ∠4 are supplementary, then:

∠2 + ∠4 = 180°

∠2 = 180° - 45°

∠2 = 135°

∠7 and ∠5 are supplementary, then:

∠7 + ∠5 = 180°

∠7 = 180° - 135°

∠7 = 45°

Bob's home will worth $296,779.25 after 12 years.

Equation used is [tex]FV = $175,000( 1 + 4.5/100)^(12)\\[/tex]

Step-by-step explanation:

Current value of Bob's house =[tex]FV = $175,000( 1 + 4.5/100)^12\\FV = $175,000( (100+ 4.5)/100)^12\\FV = $175,000( (104.5)/100)^12\\FV = $296,779.25[/tex]

market is improving at 4.5% annually.

This, means that the value of house gets appreciated by 4.5% each year from its previous year value.

This is a problem of compound interest formula

[tex]FV = PV(1+r/100)^n[/tex]

where PV is the present value of any thing

FV is the future value

r is the annual rate of interest

t is the time in number of year for which rate is applicable.

_____________________________________

Given

PV = $175,000.

r = 4.5%

t = 12 years

Value after 12 year will be given by

[tex]FV = $175,000( 1 + 4.5/100)^(12)\\FV = $175,000( (100+ 4.5)/100)^(12)\\FV = $175,000( (104.5)/100)^(12)\\FV = $296,779.25[/tex]

Thus, Bob's home will worth $296,779.25 after 12 years.

Answer:

Step-by-step explanation:

In this sense "area" refers to a geographical area in which people may or may not live; any "population" refers to the group of people living in a specific area.  We might discuss the "population" of the "Los Angeles area," which refers to people living within the geographic boundaries of the City of Los Angeles.

"Urban" characterizes a given area where the land is thickly settled with human residents (as opposed to open, commercial or rural land).  Most of the area within the boundaries of "Los Angeles" are "urban."

"Density" refers to "population density," defined as the number of people per square mile (or other measure of area); as an example we might refer to the population density of the City of Los Angeles, and that reasure might be in the area of "246,000 residents per square mile."

Answer:

The correct option is A

A) y = (1/5)x + 6

Step-by-step explanation:

The equation of the first cut shown in the graph is:

y = (1/5)x - 1

We know that a general form of linear equation is given as:

y = mx + c

Comparing both equations, we get that the slope m = 1/5

As the second cut is parallel to the first cut, it will have the same slope, that is m = 1/5

Substitute it in the general linear equation

y = mx + c

y = (1/5)x + c

We know that this equation passes through the point (0,6), substitute it in  the above equation>

6 = (1/5)(0) + c

c = 6

The equation for second cut be found by using m = 1/5 and c = 6

y = mx + c

y = (1/5)x + 6
