Answer:

  x ≈ 17.3

Step-by-step explanation:

The triangles are all similar, so the side lengths are proportional.

  short side / hypotenuse = x/30 = 10/x

  x² = 300 . . . . . . cross multiply

  x = 10√3 . . . . . . take square root

  x  ≈ 17.3

An artificial pond is stocked with an initial population of 2,500 fish. The engineers estimate a 24% decline in the fish population over time without restocking or effects of fishing. The following function models the population, where x is the number of years since the pond was made.

f(x) = 2,500(0.76)x



The mathematical range of the function is y > 0. Which statement describes how the reasonable range compares to the mathematical range?

The reasonable range has a minimum value of 2,500.
The reasonable range has a maximum value of 2,500.
The reasonable range has a reasonable minimum that cannot be determined.
The reasonable range has a reasonable maximum that cannot be determined.

Answers

Answer:

B) the reasonable range has a maximum value of 2,500

Step-by-step explanation:

The reasonable range has a maximum value of 2500.

What is mathematical range?

'The Range is the difference between the lowest and highest values.'

According to the given problem,

f(x) = 2500 × [tex]0.76^{x}[/tex]

Number of years = x

⇒ x ≥ 0

⇒ f(x) ≤ 2500 × [tex]0.76^{0}[/tex]

= 2500

Hence, we can conclude, the reasonable range has a maximum value of 2500.

Find each angle measure in the triangle.
3x°
2xº
4xº

Answers

The total measure of angles in a triangle is 180°.

3x° + 2x° + 4x° = 180°

9x° = 180°

x° = 180° ÷ 9

x° = 20

Our 3 angles are:

3(20) = 60°

2(20) = 40°

4(20) = 80°

Done.

Answer:

Step-by-step explanation:

3x+2x+4x=180

9x=180

x=180/9=20

3x=3×20=60°

2x=2×20=40°

4x=4×20=80°

Graph the logarithmic function below by moving the
key point.
y = log₂ (x)
You can only graph integer points

Answers

To graph the logarithmic function y = log₂(x), we can use the key point (1,0) and the fact that the logarithmic function is the inverse of the exponential function y = 2ˣ.

Starting at the key point (1,0), we can move to the right by increasing x by a factor of 2, since log₂(2) = 1. This takes us to the point (2,1). Similarly, we can move to the right by a factor of 2 again to get to the point (4,2), and then to (8,3), (16,4), and so on.

If we instead move to the left from the key point (1,0) by a factor of 2, we get to the point (1/2, -1), since log₂(1/2) = -1. We can continue moving to the left by dividing x by 2 to get to (1/4, -2), (1/8, -3), and so on.

The given graph of y = log₂(x) using only integer points.

The graph is symmetric about the line x=1, since log₂(x) = log₂(1/x) = -log₂(x).

2. Grant works as a salesperson at a seasonal market. During the Christmas season, he
gets a 15 percent commission on every tree he sells. If he sold 12 trees today, with an
average sale price of $35 per tree, what amount of commission will he make?

Answers

Grant will make $63 commission on 12 trees he sold.

Given that, Grant works as a salesperson at a seasonal market. He gets a 15 percent commission on every tree he sells. If he sold 12 trees then we have to calculate the amount of commission he will get if the average sales price of a tree is $35.

So, first we will calculate the amount of commission Grant will get if he sold one tree.

∴ The commission on one tree will be equals to 15 percent on the sales price of a tree i.e., $35.

⇒ 15% of $35

= 15/100 x 35

= 5.25

Therefore, Grant will get $5.25 commission on selling one tree.

He sold 12 trees on that day. So, the total amount of commission he will get on 12 trees will be equal to,

= 12 x 5.25

= 63

Therefore, $63 is the amount of commission Grant will made on the sale of 12 trees.

Step-by-step explanation:

Let there are 2x milk chocolates and 3x dark chocolates.

x = 4

Dark chocolates = 3x

Scientists are preparing two satellites to be launched. The equation y=8200xy=8200x represents the number of miles, yy, that the satellite, Space Explorer B, flies in xx hours. The satellite, Space Explorer A, flies 28800 miles in 24 hours.
How many fewer miles does Space Explorer A travel in one hour than Space Explorer B?

Answers

Answer:

Space Explorer B travels 6800 miles more than Space Explorer A in one hour.

Step-by-step explanation:

Space Explorer A travels 7000 miles less than Space Explorer B in one hour.

What is an equation?

Two or more expressions with an equal sign are defined as an equation.

Given that, Space Explorer A flies 28800 miles in 24 hours.

24 hours = 28800 miles

1 hour = 28800/24 miles

1 hour = 1200 miles

Hence, Space Explorer A travels 1200 miles in 1 hour.

Now, the equation representing the distance, y, traveled by Space Exploral B in x hours is:

y = 8200x

Substitute x = 1:

y = 8200

Therefore, Space Exploral B travels 8200 miles in 1 hour.

The difference between the distance traveled by Space Exploral B and Space Exploral A is:

8200 - 1200

= 7000

Hence, Space Explorer A travels 7000 miles less than Space Explorer B in one hour.

solve the following two equation X+Y=5
X-2Y=2

Answers

Step-by-step explanation:

x=4 and y= 1 because of 4+1=5 and add 2y to both sides

x-2y+2y=2+ 2y

x=2y+2

4-2=2

[tex]\left \{ {{x+y=5} \atop {x-2y=2}} \right.[/tex]

Here we have 2 equations in one system.

System of Equations/Simultaneous Equations are for finding the intercepts of both graphs.

We can solve these Simultaneous Equations in many ways. However, I'll be solving by substitution.

To solve by using substitution, we need to move either x or y to the another side. I'll move x term to another side for the first equation. (We'll substitute the first equation in the second.)

[tex]\left \{ {{y=-x+5} \atop {x-2y=2}} \right.[/tex]

Now we substitute y = -x+5 in x-2y = 2

[tex]x-2(-x+5)=2\\[/tex]

Then distribute -2 in (-x+5) | Note that multiplying the negative will get positive. |

[tex]x-2(-x+5)=2\\x+2x-10=2\\3x=2+10\\3x=12[/tex]

We should get this. When we get this, we move 3 to divide 12 (Opposite when moving to another side so from plus to minus and from multiply to divide.)

[tex]x=4[/tex]

But we are not done yet. We have to find the y-value. After all they are two variables equations.

If we want to find the y-value then we have to substitute x = 4 in any given equations. I'd suggest to substitute in the equation that doesn't have a coefficient with high value.

So I'll be substituting in x + y = 5 instead.

Substitute x = 4 in x + y = 5

[tex]4+y=5\\y=5-4\\y=1[/tex]

Thus, we get both x and y value. Answer in either coordinate point or writing form.

Therefore, the answer is

x = 4 when y = 1 or (4,1)

Both works. Hope this helps.

Step-by-step explanation:

We can just follow the hint.

Amount of discount = $84 - $72

                                 = $12

Percentage of discount = [tex]\frac{12}{84}[/tex] × 100%
