Answer:

3 hours

Step-by-step explanation:

Xavier can paint the average house in 4 hours

This means that in 1 hour, Xavier paints 1/4 of the house

Mohamad can do it in 12 hours

That means in 1 hour, Mohamad paints 1/12 of the house

Hence,

Together the amount of the house they can paint in 1 hour is

1/4 + 1/12

The Least common denominator is 12

(3 × 1 + 1 × 1)/1#

= 3 + 1/12

= 4/12

= 1/3

Together they can paint 1/3 of the house

The number of hours, that it would take to paint a house if they both worked together is

= 1/3 = 1

Cross Multiply

= 3 × 1

= 3 hours

Answer:

Csc(0)=24/27 and Tan(0)= 24/7

Step-by-step explanation:

We know that secant is the inverse of cos. So that Sec(x) = Cos^-1(x)= hypotenuse/adjacent. We now know that 25 is hypotenuse and 7 is the length of side adjacent to angle theta.

Given this information we can find the length of side opposite to theta, which has length 24.

Now we know:

Hypotenuse=27

Adjacent=7

Opposite=24

Csc is inverse of sin, so that scs=sin^-1=hypotenuse/opposite=27/24

and tan=opposite/adjacent=24/7

Answer:

x = 30

Step-by-step explanation:

Okay the triangle should add up to 180.

The square represents a right angle = 90°

So just do this

60° + 90° + x = 180 (collect like terms)

150° + x  = 180 (subtract 150 on both sides)

x = 30

Hope this helps ya!

Answer:

x = 30

Step-by-step explanation:

the trinagle has an angle of 180.

and the trainage has a 90°  next to the 60

So

60° + 90° + x = 180 (there are term)

150° + x  = 180

subtract 150 on both sides

150 - 150  180-150 =  x = 30

I'm pretty sure it's C. Both.

Answer:

only table A is a function

Table B has two inputes with the same outpute so it is impossible to be a function. but two of the same inputes can have different outputs

Step 1: We start by writing the equation of the line in slope-intercept form by solving for b.

[tex]-5 = 3(-1) + b\\\\-5 = -3 + b\\\\-2 = b\\[/tex]

Step 2: Now we set up the equation of the line in slope-intercept form.

[tex]y = 3x - 2[/tex]

Step 3: We can now convert the above equation from slope-intercept form to standard form.

[tex]y = 3x - 2\\\\-3x + y = -2\\\\-3x + y + 2 = 0[/tex]

The equation of the line in standard form is: D: -3x + y + 2 = 0.

Answer:

Think about it this way:

triangle KDI is supplementary to EHK. SO if we find the angles of KDI we can do the same for EHK. Additionally, the m<H in the triangle HKF is 90 degrees and since it is supplementary to EHK then the measure of h in EHK is also 90 degrees. So m<h is 90. All three angles will equal to 180 since the interior angles of any triangle equal 180°

Now, lets find the measures of KDI so we can solve for the measure of K in the triangle EHK

D in KDI is 19 degrees and the square on I in KDI indicates its a 90 degree angle. Those add up to 109 degreess meaning measure of k must equal 71 degrees (180=109=71) since the interior angles of any triangle equal 180. Therefor in the triangle EHK, h is 90, and k is 71 degrees by vertical angles theorem. 90 and 71 add up to 161 degrees meaning angle E is going to be equal to 19 (180-161=19). this, therefore means 17x-7=19

solve:

17x-7=19

17x=26

x=26/17

x=1 9/17

You can write it as a decimal, improper fraction or mixed number.

Answer:

  y = (-7/3)x +3

Step-by-step explanation:

The line has a negative slope (eliminating choices B and C) that is steeper than a line with a slope of -1, The only answer choice with a negative slope less than -1 is choice D.

__

The slope is the coefficient of x. It is "rise"/"run". Here, the line goes through grid points (0, 3) and (3, -4), so drops 7 units (rise=-7) for each 3 units to the right (run=3). Then the slope is rise/run = -7/3.

The line crosses the y-axis at y=3, so the slope-intercept equation is ...

  y = mx + b . . . . . . . . slope = m; y-intercept = b

  y = (-7/3)x +3

Answer:

7.854

Step-by-step explanation:

Answer:

-2.125

Step-by-step explanation:

Answer:

Step-by-step explanation:

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the table attached,

Two points lying on the graph are (1, 12) and (2, 24).

Slope of the line will be,

m = [tex]\frac{24-12}{2-1}[/tex]

Slope = 12

Since equation of a line passing through a point (x', y') and slope 'm' is,

y - y' = m(x - x')

Therefore, equation of the line passing through (1, 12) and slope 12 will be,

y - 12 = 12(x - 1)

y = 12x - 12 + 12

y = 12x

By comparing this equation with the equation,

y = mx + b

where 'b' = y-intercept = 0

Since, y-intercept is zero, table will represent the proportional relation between x and y.

Proportional or non proportional → Proportional

Answer:

8/3 or 2.666666..........

Step-by-step explanation:

20% = 2/3

100 / 20 = 5

so it will take 5 * 2/3 or (10/3) to paint the whole house

but use had used 2/5

so the  Answer is (10/3) - (2/5) = 8/3

Answer:

16

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

Divide by 22.5 to find the number of sides n

n = [tex]\frac{360}{22.5}[/tex] = 16

It an be concluded tat the regular polygon has 16 sides

A regular polygon is a polygon with equal angles and equal sides.

The sum of exterior angles of a regular polygon is 360°

According to the given data

One exterior angle of a regular polygon measures 22.5 °

Let us consider that the regular polygon has "n" sides

So from the exterior angle sum property of the regular polygon we can write that

[tex]\rm n \times 22.5\textdegree = 360 \textdegree\\ n = 360\textdegree /22.5\textdegree \\n = 16[/tex]

So it an be concluded tat the regular polygon has 16 sides
