i need help, what do i do?

Answer:

19

Step-by-step explanation:

The first thing is recognize that it is a rectangle and two triangles with given bases and heights.

So the first step is finding the area of both triangles, which you can do with the formula for the area of a triangle:

A = (BH)/2

Because the height is two, the area is going to be equal to the base.

The sum of the two triangles is 7.66.

Next you want to find the area of the rectangle, you can do so using the formula:

A = BH

A = 6(2)

The area of the rectangle is 13.

Find the sum of the areas of the three shapes.

3.30 + 4.36 + 12 = 19.66

Answer:

5.75x = f(x)

22.99 + 2.09x = g(x)

Step-by-step explanation:

Divide them into two parts:

Normal drinks and commemorative drinks

- With normal, only $5.75 is related (Only one drink at a time so 5.75x)

- With commemorative, $22.99 and $2.09 are related (A one time fee of $22.99, then a refill of $2.09; so 22.99 + 2.09x)

Answer:

The value  is  [tex]E(X) =  \$ 1.7067 [/tex]

Step-by-step explanation:

From the question we are told that

   The  parameters  are  α = 3, θ = 0.5

    The cost of making a unit on the first day  is  c = $2

    The selling price of a  unit on the first day is  s = $5

    The selling price of a leftover unit on the second day is  v  = $ 1

Generally the profit of a unit on the first day is

        [tex]p_1 = 5 - 2[/tex]

           [tex]p_1 = \$3 [/tex]

The profit of a unit on the second day is

       [tex]p_2 = 1 - 2[/tex]

=>     [tex]p_2 = - \$1 [/tex]

Generally the probability of making profit greater than $ 1 is mathematically represented as

    [tex]P(X >  1 ) = Gamma (X ,\alpha , \theta)[/tex]

=>   [tex]P(X >  1 ) = Gamma (1 ,3 , 0.5)[/tex]

Now from the gamma distribution table  we have that

    [tex]P(X >  1 ) =  0.67668[/tex]

Generally the probability of making profit less than or  equal to  $ 1 is mathematically represented as

       [tex] P(X \le  1 ) = 1 - P(X >  1 )[/tex]

=>     [tex] P(X \le  1 ) = 1 - 0.67668[/tex]

=>     [tex] P(X \le  1 ) = 0.32332[/tex]    

So  the probability of making  $3  is    [tex]P(X >  1 ) =  0.67668[/tex]

and  the probability of making  -$1  is   [tex] P(X \le  1 ) = 0.32332[/tex]  

Generally the value of profit per day is mathematically represented as

      [tex]E(X) =  3 *  P(X >  1 )   +   (-1  *  P(X \le 1 ) )[/tex]

=>     [tex]E(X) =  3 * 0.67668   +   (-1  *  0.32332 )[/tex]

=>     [tex]E(X) =  \$ 1.7067 [/tex]

Answer:

0 slope as it is a horizontal line when you graph it

Step-by-step explanation:

Take 2 points

Slope:-

[tex]\\ \sf\longmapsto \dfrac{-2}{7}=\dfrac{-2}{7}=m[/tex]

Now find equation of line in point slope form

[tex]\\ \sf\longmapsto y=-2/7(x+7)[/tex]

[tex]\\ \sf\longmapsto y=-2/7x-2[/tex]

Put (0,0)

[tex]\\ \tt\Rrightarrow 0=0-2[/tex]

[tex]\\ \tt\Rrightarrow 0\neq -2[/tex]

shaded region is away from origin .

So the inequality is

[tex]\\ \sf\longmapsto y\leqslant -2/7x-2[/tex]

Answer:

Take 2 points

(-7,0)

(0,-2)

Slope:-

Now find equation of line in point slope form

Put (0,0)

shaded region is away from origin .

So the inequality is

this answer is correct i got it right when i used it.

Answer:

y=3x-3

Step-by-step explanation:

since the line must pass through (0,-3), you must have the second number (or y intercept) in the equation be -3. since the slope must be 3 then it will be shown as 3x. put it all together to get y=3x-3. not sure what the -1 is doing there but y=3x-3 passes through (0,-3)

Answer: 75%

Step-by-step explanation:

Part =  52,500,000

Whole = 70,000,000

[tex]\frac{52,500,000}{70,000,000} =\frac{x}{100} \\[/tex]

Solve for x.

[tex]x=\frac{52,500,000*100}{70,000,000}[/tex]

[tex]x=\frac{5,250,000,000}{70,000,000}[/tex]

[tex]x=75[/tex]

Answer:

x=2

Step-by-step explanation:

move the 7 with the 3, now is 7+3=10

5x=10

the five cancel with the five, simplify 10 with 5 and is 2

Answer:

86%

Step-by-step explanation:

86+14=100

Since 100 is a very common percentage number, then 86% of people voted, and 14% did not.

Stephen Talked for 138 minutes.

Step-by-step explanation:

(0.10)m + 10.00 = 23.80         Given

              -10.00   -10.00      

            (0.10)m = 13.80          Subtraction Property of Equality

              /0.10       /0.10        

                      m = 138             Division Property of Equality

Answer: Sunny Horizon Cellular’s phone plan has a monthly fee of $10.00 and charges $0.10 for every minute used. Stephan’s bill for the month was $23.80. If the equation that models this situation is (0.10)m + 10.00 = 23.80, use inverse operations and properties of equality to find the number of minutes Stephan talked during the month.

Stephan talked for ✔ 138 minutes.

Answer:

A.

Step-by-step explanation:

the slope of a line is behind the x in a linear equation.

f(x)=5x-2 is a linear equation

So, the slope of f(x) is 5.

Since A is the only choice with this answer, A is correct.

Answer:

only students who have recess at 12 p.m. or later may go out

Step-by-step explanation:

Let the time after midnight be represented by t, and the temperature be y. Since the temperature increases by 1.2 degrees Fahrenheit each hour, the time taken to reach 32 degrees Fahrenheit can be gotten from:

y = 1.2t + 18

put y = 32

32 = 1.2t + 18

1.2t = 14

t = 14/1.2 = 11.67 hours

Since the recess starts at half hour or hour, hence the recess would start at t = 12 hours, i.e. at 12 p.m.

Hence only students who have recess at 12 p.m. or later may go out
