I need help please show work.

I will get in 2:16.

Now it is given that I clock out or I got out when the time was 1 hour 46 minutes.

And I have 30 minutes to go in.

So after 30 minutes, the time will be :

   1 hour +  46 minutes

+                 30  minutes  

   1 hour  +  76 minutes

Now we know that 60 minutes = 1 hour

So the time will be 2 hours and 16 minutes.

Therefore, the time at which I will get in after 30 minutes is 2:16

Answer:  There are 13 children.

Step-by-step explanation:

1. Let's call x the number of children in the classroom. We know that each child received 4 oranges, except 5 of them.

2. There were 32 oranges in total.

3. We can write this problem as an equation that represents the number of oranges distributed, as follows:

[tex]4(x-5)=32[/tex]

4. Now we solve the equation to find the value of x:

[tex]x-5=\frac{32}{4}[/tex]

[tex]x-5=8[/tex]

[tex]x=13[/tex]

5. There are 13 children in the classroom. 8 of them received oranges and the rest did not.

Answer:

error in summing terms in x

Step-by-step explanation:

x + 3x + 5x = 180 ( collect like terms on left )

9x = 180 ← ( 9x not 8x )

divide both sides by 9

x = 20

Alma made a calculation error in solving for the angles with a ratio of 1:3:5. The correct values for x, which is the smallest angle, should be 20 degrees with the middle and largest angles being 60 degrees and 100 degrees respectively.

Alma is attempting to solve for the measures of angles in a triangle with a ratio of 1:3:5. However, there seems to be a mistake in her calculation. To correct it, we start with her equation x + 3x + 5x = 180, which represents the fact that the sum of the angles in a triangle is always 180 degrees (Theorem 20).

Combining like terms we do have 9x = 180. Solving for x gives us x = 20.

Therefore, the measure of the smallest angle is 20 degrees, the middle angle is 60 degrees, and the largest angle is 100 degrees.

The sales tax that should be paid in dollars on the new price is $22

Order of Operations in Mathematics follow this following rule :

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.

Let us tackle the problem !

Given:

Initial Price = $550

Sales Tax = 3%

Percentage of Price Increase = 33¹/₃ %

Unknown:

Final Sales Tax = ?

Solution:

[tex]\texttt{Final Price} = \texttt{Initial Price} \times (100\% + \texttt{Percentage of Price Increase} )[/tex]

[tex]\texttt{Final Price} = \$550 \times (100\% + 33\frac{1}{3}\% )[/tex]

[tex]\texttt{Final Price} = \$550 \times (100\% + \frac{100}{3}\% )[/tex]

[tex]\texttt{Final Price} = \$550 \times (\frac{300}{3}\% + \frac{100}{3}\% )[/tex]

[tex]\texttt{Final Price} = \$550 \times (\frac{400}{3}\%)[/tex]

[tex]\texttt{Final Price} = \$550 \times (\frac{4}{3})[/tex]

Answer:

D. The graph contains the point (4, -10)

Step-by-step explanation:    

We have been given an equation of a function: [tex]y=4x-10[/tex]. We are asked to find which of the given statements are not true about our given function.

A. The slope of the line can be written as 4/1.  

We can see from our given equation that slope is 4 we can write 4 as 4/1 as it will not change value of 4, therefore, option A is true.

B. The graph crosses the y-axis 10 units below the origin.  

Since we know that b represents y-intercept, where line crosses y-axis. y-intercept for our given equation is -10, which means that our given line crosses y-axis at -10 (10 units below the origin), therefore, option B is true.

C. The line has a constant rate of change.

We can see that slope of line is 4 which means with each increase in x, y will increase by 4 units, which remains constant, therefore, option C is true indeed.

D. The graph contains the point (4, -10)

Since we know that y-intercept is -10, which occurs at x equals 0, therefore, the graph does not contain the point (4,-10) and option D is not true.

Answer:

3000 gallons of 12 percent is required

Step-by-step explanation:

We can use the formula

percentage * amount + percentage * amount =  percentage*total amount

We have 9 percent and 15 percent wine that we are mixing to get 12 percent wine.

We are adding g gallons and 3000 gallons to get a total of (g+3000) gallons

Substituting this information in

.09 *g + .15 * 3000 = .12 (g+3000)

Distribute

.09g +450 = .12g+360

Subtract .9g from each side

.09g-.09g +450 = .12g-0.09g+360

450 = .03g + 360

Subtract 360 from each side

450-360 = .03g

90 =.03g

Divide each side by .03

90/.03 = .03g/03

3000 = g

Answer:

Eight

Step-by-step explanation:

We have two conditions:

(1)           C + D  = 12

(2)      2C + 3D = 32          Subtract D from each side of Equation (1)

                    C = 12 - D     Multiply both sides by 5

2(12 – D) + 3D = 32          Remove parentheses

24 – 2D + 3D = 32          Combine like terms

           24 + D = 32           Subtract D from each side

                   D = 8

Answer:

coordinate of point A is (a,b)

coordinate of point C is (2c,d)

slope of AD and BC =[tex]\frac{b}{a-c}[/tex]

Step-by-step explanation:

According to midpoint formula

If we have points P [tex](x_{1} ,y_{1} )[/tex] and Q [tex](x_{2} ,y_{2} )[/tex]

then the coordinate (x,y) of mid point of line PQ is given by

[tex]x=\frac{x_{1} +x_{2} }{2}[/tex] and [tex]y=\frac{y_{1} +y_{2} }{2}[/tex]

now from the given diagram A is the mid point of line joining  R(0,0) and S(2a,2b)

Using midpoint formula, coordinates of point A is given by

[tex]x=\frac{0+2a}{2}= a[/tex] and [tex]y=\frac{0+2b}{2} =b[/tex]

so we have

coordinate of point A is (a,b)

Also C is the midpoint of line joining T (2c,2d) and V(2c,0)

coordinate of point C is given by

[tex]x= \frac{2c+2c}{2} =2c[/tex] and [tex]y=\frac{2d+0}{2} =d[/tex]

so we have

coordinate of point C is (2c,d)

it is given that coordinate of point B is (a+c, b+d) and coordinate of D is (c,0)

If we have points P [tex](x_{1} ,y_{1} )[/tex] and Q [tex](x_{2} ,y_{2} )[/tex]

then the slope of PQ =[tex]\frac{y_{2} -y_{1} }{x_{2}-x_{1}  }[/tex]

hence slope of AD= [tex]\frac{0-b }{c-a} [/tex]

                                 =[tex]\frac{-b}{c-a}[/tex]

                                  =[tex]\frac{-b}{-(a-c)}[/tex]

                                  =[tex]\frac{b}{a-c}[/tex]

and slope of BC  =[tex]\frac{d-(b+d)}{2c-(a+c)}[/tex]

                            =[tex]\frac{d-b-d}{2c-a-c}[/tex]

                             =[tex]\frac{-b}{c-a}[/tex]

                              =[tex]\frac{b}{a-c}[/tex]

so we have

slope of AD and BC =[tex]\frac{b}{a-c}[/tex]

Answer:

Co-ordinates of A are ( a, b )

Co-ordinates of C are ( 2c, d )

Slope of line segments AD and BC is [tex]\frac{-b}{c-a}[/tex]

Step-by-step explanation:

We know that, the co-ordinates of the mid-point of a line segment having end points (x,y) and [tex](x_{1} , y_{1} )[/tex] is [tex](\frac{x+x_{1} }{2} , \frac{y+y_{1} }{2} )[/tex]

Now as 'A' is the mid-point of the line segment RS having end points (0,0) and (2a,2b).

The co-ordinates of A will be ( [tex]\frac{0+2a}{2}[/tex], [tex]\frac{0+2a}{2}[/tex] ) i.e [tex]( a, b )[/tex]

Now as 'C' is the mid-point of the line segment TV having end points (2c,2d) and (2c,0).

The co-ordinates of C will be ( [tex]\frac{2c+2c}{2}[/tex], [tex]\frac{2d+0}{2}[/tex] ) i.e. [tex]( \frac{4c}{2} , \frac{2d}{2})[/tex] i.e. [tex]( 2c, d )[/tex].

Further, we need to find the slope of line segments AD and BC.

AD has end points [tex]( a, b )[/tex] and [tex]( c, 0 )[/tex]. Then the slope of AD will be [tex]\frac{0-b}{c-a}[/tex] i.e [tex]\frac{-b}{c-a}[/tex]

Similarly, BC has end points [tex]( a+c, b+d )[/tex] and [tex]( 2c, d )[/tex]. Then the slope of BC will be [tex]\frac{d-b-d}{2c-a-c}[/tex] i.e [tex]\frac{-b}{c-a}[/tex]

Hence, the slope of AD and BC is [tex]\frac{-b}{c-a}[/tex].

Answer:

Answer:  3240 = 2^3×3^4×5

Factor the following integer:

3240

The last digit of 3240 is 0, which means it is even. Therefore 3240 is divisible by 2:

3240 = 2 1620:

3240 = 2×1620

The last digit of 1620 is 0, which means it is even. Therefore 1620 is divisible by 2:

1620 = 2 810:

3240 = 2×2×810

The last digit of 810 is 0, which means it is even. Therefore 810 is divisible by 2:

810 = 2 405:

3240 = 2×2×2×405

405 is not divisible by 2 since 405 is odd and 2 is even:

3240 = 2×2×2×405 (405 is not divisible by 2)

The sum of the digits of 405 is 4 + 0 + 5 = 9, which is divisible by 3. This means 405 is divisible by 3:

405 = 3 135:

3240 = 2×2×2×3×135 (135 is not divisible by 2 since 405 is not)

The sum of the digits of 135 is 1 + 3 + 5 = 9, which is divisible by 3. This means 135 is divisible by 3:

135 = 3 45:

3240 = 2×2×2×3×3×45 (45 is not divisible by 2 since 135 is not)

The sum of the digits of 45 is 4 + 5 = 9, which is divisible by 3. This means 45 is divisible by 3:

45 = 3 15:

3240 = 2×2×2×3×3×3×15 (15 is not divisible by 2 since 45 is not)

The sum of the digits of 15 is 1 + 5 = 6, which is divisible by 3. This means 15 is divisible by 3:

15 = 3 5:

3240 = 2×2×2×3×3×3×3×5 (5 is not divisible by 2 since 15 is not)

Divide 3 into 5:

| 1 | (quotient)

3 | 5 |  

- | 3 |  

| 2 | (remainder)

5 is not divisible by 3:

3240 = 2×2×2×3×3×3×3×5 (5 is not divisible by 2 or 3)

No primes less than 5 divide into it. Therefore 5 is prime:

3240 = 2×2×2×3×3×3×3×5

There are 3 copies of 2, 4 copies of 3 and 1 copy of 5 in the product:

Answer:  3240 = 2^3×3^4×5

3,240 =

Answer:

If he sells $2500 worth of merchandise, his salary is $800.

Step-by-step explanation:

You can find a function that gives you his salary as a function of the sales.

You have two points: (100, 500) and (700, 575).

y = mx + b

m = (575 - 500)/(700 - 100) = 75/600 = 0.125

Now use point (100, 500) to find b.

y = mx + b

500 = 0.125(100) + b

500 = 12.5 + b

b = 487.5

y = 0.125x + 487.5

If he sells $2500, then x = 2500.

y = 0.125x + 487.5

y = 0.125(2500) + 487.5

y = 800

If he sells $2500 worth of merchandise, his salary is $800.

The units digit of 23^23 is 7. This is found using the power cycle of 3 (the units digit of the base number), which is 3, 9, 7, 1 and the remainder when the exponent 23 is divided by the length of this power cycle (4).

To find the units digit of 2323, one needs to understand a pattern in power cycles. For any number, the units digit will repeat in a certain cycle when the number is raised to higher powers. For number 3, every fourth power goes back to the value 1. Thus, the cycle for the number 3 is 3, 9, 7, 1.
