tysm. Have a wonderful day...

Exact Answer:     x = 16/3

Approximate Answer:      x = 5.333

=======================================================

Work Shown:

base = 3x-1

height = x

area of triangle = (base*height)/2

40 = x*(3x-1)/2

40*2 = 3x^2 - x

80 = 3x^2 - x

0 = 3x^2 - x - 80

3x^2 - x - 80 = 0

Now apply the quadratic formula

[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(-1)\pm\sqrt{(-1)^2-4(3)(-80)}}{2(3)}\\\\x = \frac{1\pm\sqrt{961}}{6}\\\\x = \frac{1\pm31}{6}\\\\x = \frac{1+31}{6} \ \text{ or } \ x = \frac{1-31}{6}\\\\x = \frac{32}{6} \ \text{ or } \ x = \frac{-30}{6}\\\\x = \frac{16}{3} \ \text{ or } \ x = -5\\\\x \approx 5.333 \ \text{ or } \ x = -5\\\\[/tex]

A negative height doesn't make sense, so we ignore x = -5

The only solution is x = 16/3 which approximates to x = 5.333

Answer:

Triangle: 63 square units    Rhombus: 56 square units

Step-by-step explanation:

Rhombus formula: Base x Height

4 x 14 = 56

Triangle formula: 1/2 x Base x Height

6 x 21= 126  

126 x 1/2 = 63

Step-by-step explanation:

Area of a rectangle is l*w  l=12 and w=6: 12*6=70

Area of triange A is 1/2*b*h, b=3 and h=6: 1/2*3*6=9

Area of triangle B is 1/2*b*h, b=3 and h=6: 1/2*3*6=9

Area of parallelogram is Area of rectangle- Area of triangle A - Area of triangle B: 70-9-9=52

Answer:

Step-by-step explanation:

We can make this into the equation 25 + x = 4x

we isolate the equation by subtracting x from 4x. (3x)

Therefore, 25 = 3x. Therefore, Hema is 8.

Answer: See explanation

Step-by-step explanation:

Your question isn't complete but I believe that you want to know the number of rides that Katie can take.

Based on the information in the question, we can form an equation. Let the number of rides that Katie can take be represented by x. Therefore,

12 + (1.25 × x) = 50

12 + 1.25x = 50

1.25x = 50 - 12

1.25x = 38

x = 38/1.25

x = 30.4

Therefore, Katie can take at most 30 rides.

Answer: The number of units sold when the manufactures home income equals the manufactures expenses

Step-by-step explanation:

The solution to f(x) = g(x) represent that manufacturer is on break even.

Break-even analysis Break even is the point where the income of a business matches the expenses required to run that business. Also in other words it tell us the point at which you will have enough sales to cover all of the costs involved.

Here as it is given that the income f(x) to its expenses g(x) for x number of units sold is equal.

Therefore, its state will be break even.

Step-by-step explanation:

I=?

P=$7000

R=4% or 0.04

T=9

I=($7000)(0.04)(9)

(7000)(0.04)= 280

280*9= $2520

the interest after nine months is $2520

Step-by-step explanation: As the number of trials gets larger the average of the trials approaches the expected value

Answer:

C. As the number of trials gets larger, the average of the trials approaches the expected value.

Step-by-step explanation:

The statement that is true would be that, as the number of trials gets larger, the average of the trials approaches the expected value. A certain random experiment can have a various number of trials, while the expected value is going to be the average of those trials. The more trials that an experiment has, the more data that can be gathered and the average can be better calculated. This average keeps getting closer and closer to the expected value as more trials are completed and the data keeps repeating certain values.

We can use the Pythagorean Theorem to solve the triangle for x.

[tex]25^2=14^2+x^2[/tex]

[tex]625=196+x^2[/tex]

[tex]x^2=429[/tex]

[tex]x=\sqrt{429}[/tex]

x≈20.7

Answer:Replacing x with -x will reflect a graph across the y-axis. Multiplying x by 3 before the function is applied will compress the graph horizontally. This means the correct choice is D.

Answer:

15 inches

Step-by-step explanation:

Volume of a pyramid = 1/3 x ( length² x height)

4500 = 1/3 x ( length² x height)

height = 1/2 x length

4500 = 1/3 x ( length² x 1/2length)

multiply both sides of the equation by 6

27000 =  ( length² x length)

find the cube root of 27300

length = 30

height = 1/2 x 30 = 15in
