Option A: 1/3(3.14)(3cm)^2(18cm) is the correct answer

Step-by-step explanation:

Given

Diameter of Cone = d = 6 cm

Radius will be:

r = d/2 = 6/2 = 3 cm

Height of cone = h = 3d = 18 cm

The volume of cone is given by:

[tex]V = \frac{1}{3}\pi r^2h[/tex]

Putting the values

[tex]V = \frac{1}{3} (3.14)(3)^2(18)[/tex]

Hence,

Option A: 1/3(3.14)(3cm)^2(18cm) is the correct answer

Answer:

[tex]5\frac{2}{3}[/tex] miles.

Step-by-step explanation:

Kevin recorded the distances he ran last week in the table attached to this question.

Now, the total number of miles he ran on Monday through Wednesday is the same as the total number of miles he ran on Thursday and Friday.

Hence, {x + (x + 9) + (x + 4)} = {2x + (4x - 2)}

⇒ 3x + 13 = 6x - 2

⇒ 9x = 15

⇒ [tex]x = \frac{15}{9} = \frac{5}{3}[/tex]  

Therefore, he ran on Wednesday = x + 4 = [tex]\frac{5}{3} + 4 = \frac{17}{3} = 5\frac{2}{3}[/tex] miles. (Answer)

Answer: 9 miles

Step-by-step explanation:

x + x + 9 + x +4 = 2x + 4x-2

Collecting like terms

x + x + x +9 + 4 = 2x + 4x -2

Collect like terms

3x +13 = 6x -2

3x - 6x = -2 -13

-3x = -15

Divide both side by -3

x = 5

Therefore ; total number he ran on Wednesday

x + 4

If x = 5

Therefore total number he ran on Wednesday = 5+4

= 9

Answer:

The two integers are -47 and -48.

Step-by-step explanation:

Let the two consecutive integers be [tex]$ (n - 1) $[/tex] and [tex]$ n $[/tex].

Given that their sum is -95.

⇒ (n - 1) + n = - 95

⇒ 2n - 1 = - 95

⇒ 2n = - 94

Dividing by 2 throughout, we get:

n = - 47

⇒ n - 1 = - 47 - 1 = - 48

Therefore, the two integers should be - 47 and - 48.

Answer:

Step-by-step explanation: since X is greater than 3, then X can assume all numbers great than 3.

Answer:

Step-by-step explanation:

x > 3 - we read: all numbers greater than number 3

Therefore:

#1: NOT, because -1 < 3 and -2 < 3

#2: NOT, because all numbers are less than 3

#3: NOT, because 3 is not greater than 3

#4: YES, because all numbers are greater than 3.

Answer:

[tex]4\dfrac{1}{6}\ \text{kilometers per minute}[/tex]

Step-by-step explanation:

The graph shows a proportional relationship between the number of kilometers traveled (y) and the number of minutes spent traveling (x). This graph passes through the point (75,30). This means that in 30 minutes (x = 30), it was traveled 75 kilometers.

To find unit rate, divide the number of kilometers by the number of minutes:

[tex]\dfrac{75}{30}=\dfrac{25}{6}=4\dfrac{1}{6}\ \text{kilometers per minute}[/tex]

Using the cross product property on this proportion gives us the following equation:

20 (2x - 9) = 10 (9)

Use the distributive property and multiply

40x - 180 = 90

Add 180 to both sides

40x = 270

Divide 40 from both sides

x = 270/40

Simplify fraction

x = 27/4

The cross product is a type of multiplication between vectors that results in a vector product. It has the distributive property and is anticommutative.

The cross product is a type of multiplication between vectors that results in a vector product. It is denoted by the symbol A x B and is also known as the vector product.

The cross product has the distributive property, which allows us to distribute a vector across the sum of two other vectors. For example, A x (B + C) = (A x B) + (A x C).

The cross product is anticommutative, meaning that the order in which we multiply two vectors matters. A x B = -B x A.

[tex]g(x) =\frac{1}{x+4}+4[/tex]

OR

[tex]g(x) = \frac{x+5}{x+4}[/tex]

Step-by-step explanation:

The function transformations are defined as:

Shifting function upwards b units

[tex]f(x) => g(x) = f(x)+b[/tex]

Shifting functions to the left b units

[tex]f(x) => g(x) = f(x+b)[/tex]

Given function is:

Shifting the function 4 units to the left will give us:

Now shifting the function 4 units upwards

[tex]g(x) = \frac{1}{x+4} + 4[/tex]

Simplifying

[tex]g(x) = \frac{1+x+4}{x+4}\\= \frac{x+5}{x+4}[/tex]

The new equation will be:

Tax on her normal wage is $ 6755

She can work 176 hours in a year and still remain in the same tax category

Step-by-step explanation:

Becky earns $633.81 for a 40 hour week.

Her normal monthly  wage is $ 633.81 *4 = $ 2535.24

Her annual income is $ 2535.2 *12=  $ 30,422.88

Tax on her annual income is  $30,422.88- $ 20,700= $9722.88

Tax on $ 20,700 is $ 3060

Tax on remaining $ 9722.88 is 0.38*9722.88=  $36,95

Total tax is $ 3060 + $ 3695= $ 6755

She can earn up to ( $ 36,000- $ 30, 423=) $ 5577 to remain in the same tax bracket.

She earns  $633.81/40= $ 15.84 in one hour

She gets twice the wage for the overtime  $ 31. 69

No of hours she can work = $5577/ $ 31.69 = 175.98 almost 176 hours

Answer (2 answers):

x = -2/5,  x = -14/5

Step-by-step explanation:

First step is to try and get the absolute value by itself on one side and everything else that's not inside the absolute value on the other side.

9|5x+8|=54

|5x+8| = 54/9

|5x+8| = 6

Remember how absolute values turn everything positive? For example

|-4|=4, but |4|=4 as well. So we must do the same to our problem by splitting up the absolute equation into two parts.

|5x+8| = 6     and     |-(5x+8)| = 6

now solve the first equation.

(Just remove the absolute value sign and solve it normally)

5x+8 = 6

5x = -2

x = -2/5

Now solve the other equation

-(5x+8) = 6

-5x - 8 = 6

-5x = 14

x = -14/5

[tex]x_{2}[/tex] = 6                                [tex]y_{2}[/tex] = 2

[tex]x_{4}[/tex] = -9                               [tex]y_{4}[/tex] = -6

This shows that that is relationship between the values of x and the values of y.

All the values of x represent the domain and all the values of y represent the range.

Answer:

45 degrees

Step-by-step explanation:

because 2 and 5 are vertical angles they are therefore congruent by definition, 5 is half of one and one is a right angle so measure angle 2 = 45 degrees

Answer:

50

Step-by-step explanation:

The total of all 6 angles make a circle, which equals 360°. Using the information below the figure,

2 * m∠5 = 90°, since 2 * m∠5 = m∠1 and ∠1 is a right angle.

Because ∠1, ∠5, and ∠6 are on one side of line L, they must equal 180°, and if ∠1 equals 90°,

m∠5 + m∠6=90°.

Since 2 * m∠5=m∠1 and m∠1=90°, m∠1 must be 45°. And by Transitive Property, m∠6 also equals 90°.

If the total measure of the angles is 360° and ∠1, ∠5, and ∠6 add up to 180°, ∠2, ∠3, and ∠4 must also add to 180°.

m∠6=m∠3 - 20°. We know that m∠6 is 45°, so we put that into an equation. I am going to use x as the measure of ∠3.

45=x-20  >>>  20+45=x-20+20  >>>  20+45=x  >>>  65=x  >>>  x=m∠3  >>>  m∠3=65

m∠3=m∠4, so m∠3+m∠4=65+65, or 130. And like I said above, ∠2, ∠3, and ∠4 must add to 180°. 180 minus 130 (the measure of ∠3 + ∠4) = 50, which has to be the measure of ∠2
