3 goes into 15. six does not.

Answer:

9 essay questions.

Step-by-step explanation:

We have been given that ada’s history teacher writes a test for the class with 26 questions. We can represent this information in an equation as:

x+y=26

We are also told that multiple choice worth 3 points each, so total number of points for x questions will be 3x.

As essays worth 8 points each, so total number of points for y questions will be 8y.

Since the test is worth 123 points, so we can represent this information in an equation as:

3x + 8y= 123

Now we will use substitution method to solve system of linear equations.

From equation (1) we will get,

x=26-y

Substituting this value in equation (2) we will get,

3×(26-y)+8y=123

78-3y+8y=123

78+5y=123

Let us subtract 78 from both sides of our equation.

78-78+5y=123-78

5y=45

Let us divide both sides of our equation by 5.

5y/5=45/5

y=9

The value of c is equal to [tex]7\sqrt{2}[/tex]

Data:

To solve this problem, we need to use trigonometric ratio SOHCAHTOA.

Since we have opposite and hypothenuse value, we can use sine angle for this.

[tex]sin \theta = \frac{opposite}{hypothenuse}[/tex]

Let's substitute the values into the formula

[tex]sin45 = \frac{7}{c}\\ c = \frac{7}{sin 45} \\c = 7\sqrt{2}[/tex]

Answer:

  A)  7/5

Step-by-step explanation:

An exponential equation like this can be solved by using logarithms, or by rewriting the bases so they are the same.

  3^(2h-1) = 27^(-h+2)

Using 27 = 3^3, we can write the equation in terms of powers of 3:

  3^(2h-1) = (3^3)^(-h+2)

  3^(2h -1) = 3^(-3h +6)

Equating exponents gives ...

  2h -1 = -3h +6

  5h = 7 . . . . . . . . . add 1+3h

  h = 7/5 . . . . . . . divide by 5

__

Additional comment

When solving this using a graphing calculator, it is often convenient to write the equation in such a way that the solution is an x-intercept. Here, we can do that by subtracting the right-side expression from both sides:

  3^(2h-1) -27^(-h+2) = 0

The solution is h = 1.4 = 7/5.

Answer:

h=7/5

Step-by-step explanation: Why because when you make the calculations it is 0.66ft so it is A

Answer:

Since the box is 20 cm long. I decided that we would need to divide 20 by 2.54. Once you do that you should be able to get 7.87401574803. But that wouldn't be correct unless we round it a bit.

[tex]m=-1[/tex]

Step-by-step explanation:

Given the following question:

Point A = (-8, 5) = (x1, y1)
Point B = (3, -6) = (x2, y2)

To find the answer we have to use the formula to calculate slope or rise over run.

[tex]m=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{-6-5}{3--8} =\frac{-11}{11}[/tex]

Answer:

See below.

Step-by-step explanation:

i) A + B + C

= 4x² + y² - 6xy + 3y² + 12x² + 8xy + 6x² + 8y² + 6xy

= 24x² + 12y² + 8xy

ii) 2A + B - C

= 2(4x² + y² - 6xy) + 3y² + 12x² + 8xy - 6x² - 8y² - 6xy

= 8x² + 2y² - 12xy + 3y² + 12x² + 8xy - 6x² - 8y² - 6xy

Answer:

Measure of ∠WOV = 60°

Complementary angles

Step-by-step explanation:

       The box shows us that is equal to 90°. Angles ∠WOV and ∠WOX are complementary angles because we get 90° when we add them together. Since we are given the measure of ∠WOX we can subtract it from 90° to find the measure of ∠WOV.

90° - 30 ° = 60°

Here is an image of how to solve the inequality:

Answer:

Step-by-step explanation:

Given two points, the equation for the line through them can be found using the slope formula and the slope-intercept form.

The slope formula is ...

  m = (y2 -y1)/(x2 -x1)

  m = (4 -(-4))/(0 -6) = 8/-6 = -4/3 . . . . slope of the line

The y-intercept is 4, given by the second point.

The slope-intercept equation for a line is ...

  y = mx +b . . . . . . line with slope m and y-intercept b

  y = -4/3x +4 . . . . . line with slope -4/3 and y-intercept 4

__

The x-intercept can be found by solving for x when y=0.

  0 = -4/3x +4

  0 = 4x -12 . . . . multiply by -3

  0 = x -3 . . . . . . divide by 4

  3 = x . . . . . . . . subtract 3

The x-intercept is (3, 0).

The line can be graphed by plotting the given points and drawing the line through them.

Answer:

Slope: [tex]-\frac{4}{3}[/tex]

Y int. : (0,4)

X int. : (3,0)

Step-by-step explanation:

Equations to remember:

[tex]y = mx + b\\\\\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

--------------------------------------------

[tex](x_{1}, y_{1}) = (6, -4)\\\\(x_{2}, y_{2}) = (0,4)[/tex]

--------------------------------------------

SLOPE

You want to set up your equation for finding slope like this:

[tex]\frac{4 - (-4)}{0 - 6}[/tex]

4 - (-4) will become 4 + 4. This is because there is a -1 in front of the parenthesis.

A negative number times a negative number will always equal a positive number.

[tex]-\frac{8}{6}[/tex]

when simplified/divided by 2, which is the number you want:

[tex]-\frac{4}{3}[/tex]

This is your slope or your m in y = mx + b

---------------------------------------------------------------

Y INTERCEPT

Use one of your points.

I'll use (0,4) as an example.

Set up your equation like this:

[tex]4 = -\frac{4}{3}(0) + b[/tex]

Since your slope is being multiplied by ZERO, you can just eliminate your mx or slope.

This means that 4 = b!

That's your Y Int, which you'll find was one of the given points, (0,4).

---------------------------------------------------------------

From there, if you use a graph, you should find that your X Int is (3,0).

The value of x when y is 14.4 is 5.

It is given that

y ∝ 1/x

y = k/x....(1)

Where k is a constant of proportionality

The constant of proportionality is the ratio that relates two given values.

When y =6, x=12

Means, 6 = k/12

k = 72

Putting the value of k in equation (1)

y = 72/ x

14.4 = 72/ x

The area of a sector with a central angle of 2π/9 radians and a diameter of 20.6 mm is 37.01 mm²

It is given that

Central angle α= 2π/9

Diameter d= 20.6mm

So, radius r= 10.3mm

The area of a sector with central angle α and radius r is 0.5*r²*α

So, area of given sector = 0.5*10.3² * 2π/9

Area of given sector = 37.01 mm²

Therefore, the area of a sector with a central angle of 2π/9 radians and a diameter of 20.6 mm is 37.01 mm².
