Answer:

39 yd^2

Step-by-step explanation:

First, we must divide the shape into quadrilaterals. The best, and easiest, way to do this is to cut along the line in the middle, below the lower 2 yd mark. This will give us a 1 yard by 3 yard rectangle, 4 yard by 8 yard rectangle, and 2 yard by 2 yard square. The next thing to do is to find the area of each location of the backyard using the A = l x w equation. 1 x 3 =  3, 2 x 2 = 4, 4 x 8 = 32. The final step is to add these individual areas, giving us 39 square yards.

We can find the equation that represent the equation of ellipse we can identify by the major axis and minor axis, and center.

An ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called focus adds up to a constant. It is taken from the cone by cutting it at an angle.

We have equation of ellipse:

[tex]\rm \dfrac {y^2}{25}+\dfrac{x^2}{4}=1[/tex]

[tex]\rm \dfrac {y^2}{5^2}+\dfrac{x^2}{2^2}=1[/tex]

Here a = 5, and b = 2

Major axis is 2a = 2(5) = 10

Minor axis is b = 2(2) = 4

Here a graph is not given, if

Thus, we can find the equation that represent the equation of ellipse we can identify by the major axis and minor axis, and center.

Step-by-step explanation:

The statement "*Remember ..." tells you how to identify the functional relations.

In the top diagram, each x-value maps to more than one y-value. Effectively, that means x is repeating (not a function).

In the set of ordered pairs, the value 3 shows up as an x-value more than once. It repeats (not a function).

In the graph, each value of x is shown as corresponding to exactly one value of y. The graph shows y as a function of x.

Answer:

D = √193 units

or

D = 13.892 units

Step-by-step explanation:

Given:

(7, 4) and (-5, -3)

Calculate the distance

Solution:

[tex] \rm \: Distance (D) = \sqrt{( x_{2} - x_{1}) {}^{2} + (y_{2} - y_{1) {}^{2} }} [/tex]

Now, substitute the values given:

[tex] \rm \: D = \sqrt{ \{( - 5) - 7 \}^{2} + \{( - 3) - 4 {}^{} \} {}^{2} } [/tex]

[tex] \rm \: D = \sqrt{ \{12 \}^{2} + \{( - 3) - 4 {}^{} \} {}^{2} } [/tex]

[tex] \rm \: D = \sqrt{ 144 + \{( - 3) - 4 {}^{} \} {}^{2} } [/tex]

[tex]\rm D = \sqrt{144 + \{ 7\}{}^{2} } [/tex]

[tex] \rm \: D = \sqrt{144 + 49} [/tex]

[tex] \boxed{\rm \: D = \sqrt{193}} [/tex]

[tex] \boxed{\rm \: D =13 .892}[/tex]

Thus, Distance between the two given points will be √193 or √13.892 units.

Answer:

[tex]\bf \sqrt{193}[/tex] units or 13.9 units is the distance.

Step-by-step explanation:

Considering the hypothesis tested and the p-value of the test, the correct option is given by:

There is sufficient evidence that there is a difference in mean cholesterol level when using medicine X and medicine Y.

At the null hypothesis, it is tested if there is no difference between the cholesterol levels, that is:

H₀:Hₓ-H

At the alternative hypothesis it is tested if there is a difference, hence:

H₀:Hₓ-H≠0

The p-value is of 0.003 < 0.01, hence we reject the null hypothesis and conclude that there has was a difference, hence the correct option is given by:

There is sufficient evidence that there is a difference in mean cholesterol level when using medicine X and medicine Y.

Answer:

1017.36 m²

Step-by-step explanation:

Info:

Diameter: 36m

π: 3.14

---

If the formula for area of circle is: A = πr², and the radius is 18 (half of 36)

Then to find the area, we just multiply π with 18².

18 x 18 = 324.

324 x 3.14 = 1017.36

The area of the circle is 1017.36 m²

Hi Student!

The first step to most problems is to determine the important information that is provided in the given problem statement.  In this problem we can see that we are given a diameter of a circle which is 36 meters.  Another important thing that we can determine is that the question is asking for us to find the area of the circle using 3.14 for π.

Now that we have collected our important information we can move onto the next step which isn't to find the area yet.  First, we need to determine what the radius of our circle is.

Determine the radius

Now, we can finally plug in our values into the area of a circle equation and solve.  The only thing that we need to find the area is the radius which we determined from the previous step.

Plug in the values

Expand the exponent

Multiply the final two numbers

Therefore, the area of a circle with a diameter of 36 meters is 1017.36 meters squared.

Answer:

Step-by-step explanation:

The equation that he can use to find n, the number of gallons of water he should remove is; (3.52)/(22 - n) = 24/100

Let us first find the amount of ammonia in 22 gallons of 16% ammonia solution.

This gives;

Amount = 16% * 22 gal

Amount = 3.52 gal

Now, the amount of ammonia remains the same after the water evaporates, but the total amount of solution will reduce by the amount of water that evaporates.

Amount of ammonia = 3.52 gal

Amount of water that remains = 22 - n

Desired concentration = 24% = 24/100

Thus, the equation is;

(3.52)/(22 - n) = 24/100

Answer:

30%

Step-by-step explanation:

Do 6,000 minus 2,820 which we get 3,180. The 3 is in 30% so 30 is your answer with the percentage sign.

Answer:

59 degrees

Step-by-step explanation:

180 - 126 = 54

6x-1 + 5x + 17 +54 =180

11x + 70 = 180

11x = 180 -70

11x = 110

x =10

Therefore

6(10) - 1 = 59 degrees
