If the foundation of a new house requires 240 cubic feet of concrete, then how many cubic yards of concrete should be ordered?​

Answer:

Sorry,for the answer it is too difficult brother .

Answer:

6. x° is approximately 21.04°

7. x° is approximately 39.56°

8. x° is approximately 58.03°

9. x° is approximately 72.85°

Step-by-step explanation:

6. In the given right triangle (a triangle with the measure of one of the interior angles equal to 90°, indicated by the small square between two sides) , we have;

The hypotenuse side length = 15

The adjacent side to the given reference angle, x° = 14

By trigonometric ratio, we have;

[tex]cos\angle X = \dfrac{Adjacent\ leg \ length}{Hypotenuse \ length}[/tex]

[tex]\therefore cos(x^{\circ}) = \dfrac{14}{15}[/tex]

To find the value of x°, we make use of the inverse cosine function, arccos found on a scientific calculator, as follows;

x° = arccos(14/15) ≈ 21.04°

x° ≈ 21.04°

7. In the given right triangle, we have;

The length of the opposite side to the given reference angle, x° = 19

The length of the adjacent side to the given reference angle, x° = 23

By trigonometric ratios, we have;

[tex]Tan(\angle X) = \dfrac{Opposite \, side \ length}{Adjacent\, side \ length}[/tex]

[tex]\therefore tan(x^{\circ}) = \dfrac{19}{23}[/tex]

Therefore;

x° = arctan(19/23) ≈ 39.56°

x° ≈ 39.56°

8. In the given right triangle, the adjacent side to the reference angle, x° and the hypotenuse side are given, therefore, we have;

x° = arccos(9/17) ≈ 58.03°

x° ≈ 58.03°

9. The opposite side to the reference angle and the hypotenuse side are given

By trigonometric ratio, we have;

[tex]sin\angle X = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]

[tex]\therefore sin(x^{\circ}) = \dfrac{43}{45}[/tex]

x° = arcsin(43/45) ≈ 72.85°

x° ≈ 72.85°.

Answer:

Step-by-step explanation:

Each football weighs 7/8 of a pound. Let's convert 7/8 to a decimal by dividing its numerator by its denominator. ANSWER: The total weight of the football, in pounds, is 7 lb.

Answer:

area = 50.24 in²

Step-by-step explanation:

radius = 8/2 = 4"

area = πr² = (3.14)(4²) = 50.24 in²

Answer: c

Step-by-step explanation:

Because the total should be at the end plus how much pounds it is so c

Answer:

29.50 degrees to the nearest hundredth.

Step-by-step explanation:

First we can find the measure of < CGB by using the Cosine Rule:

cos <CGB = (11^2 - 5.3^2 - 6.9^2) / (-2 * 5.3 * 6.9)

= -0.61936

So m < CGB = 128.27 degrees.

Now we can find the measure of x by using the Sine Rule:

11 / sin 128.27 = 6.9  / sin x

sin x =  6.9 * sin 128.27 / 11

= 0.49248

x = 29.5035 degrees

Answer:

x is around 29.5

Step-by-step explanation:

Let's just use the law of cosines.

[tex]c^2 = a^2 + b^2 - 2ab\cos\angle (ab)\\\\6.9^2 = 5.3^2 + 11^2 - 2\cdot5.3\cdot11\cdot \cos x^{\circ}\\47.61 = 28.09 + 121 - 116.6\cdot\cos x^{\circ}\\~\\cos x^{\circ} = \frac{149.09 - 47.61}{116.6} = \frac{101.48}{116.6}\\~\\x^{\circ} = \arccos\frac{101.48}{116.6}\\~\\x^{\circ} \approx 29.5^\circ[/tex]

Answer:

The answer is 4

Step-by-step explanation:

The experimental probability will be  [tex]P =\dfrac{1}{8}[/tex]

The experimental probability of an event occurring is the number of times that it occurred when the experiment was conducted as a fraction of the total number of times the experiment was conducted.

The sample will be b= 16

favourable outcomes = 2

As she spends the spinner 16 times

The experimental probability =  2   /   16  =  1   /  8

Answer:

the plot points should be: m - (-1,-5) l - (-1,-8) n - (-3,-9)

Step-by-step explanation:

i'm not the greatest at explaining but i'll give it a shot. When you are doing a reflection of plot point shape, you need to reflect it over/under the x or y axis (hence the name "reflection") If you are reflecting over any of the axis, y or x, you need to first find the plot points of the original image. Then, you move over to that same spot to reflect it. For example, the shape 1,1, 1,2, 2,1 and 2,2. that's a square right? right. i would be a little worried if you didn't know that. anyways, you would then move to those points to reflect on the axis. We'll reflect on the y axis. You would then move it to the -1,1, -1,2, -2,1 and -2,2.

i'm super bad at explaining stuff but i hope this helps !

Step-by-step explanation:

a is .75 shaded in then there are 5 sections in the shaded area

Answer:

D is the correct option.

Step-by-step explanation:

I used the elimination method to solve this. so we can see that there is 100 boxes and we need to 75 to be shaded. only C and D have 75 squares shaded so we can eliminate A and B. now we have to divide by 5. Square C is divided 3 times while square D is divided 5 times, so square D is correct.

Step-by-step explanation:

We can use Pythagorean Theorem to find leg BC.

[tex]AB^2=AC^2+BC^2[/tex]

[tex]24^2=12^2+BC^2[/tex]

[tex]576=144+BC^2[/tex]

[tex]BC^2=432[/tex]

[tex]BC=\sqrt{432}[/tex]

[tex]BC=2\sqrt{108}[/tex]

[tex]BC=4\sqrt{27}[/tex]

[tex]BC=12\sqrt{3}[/tex]

So, the measure of leg BC is 12√3.
