Answer:
13 white cars
Step-by-step explanation:
Let us represent:
Number of
Red cars = x
Blue cars = y
White cars = z
Sharon has 23 toy car that are colored red, blue, and white.
x + y + z = 23
x = 4
2 fewer blue cars than red
y - 2 = x
y - 2 = 4
y = 4 + 2
y = 6
Hence,
x + y + z = 23
4 +
Number of white cars is calculated as:
23 - (6 + 4)
23 - 10
= 13 white cars

James needs to choose a cell phone plan. Sprint costs $40 per month and $0.12 per text message. Verizon is only $25 per month, but each text message costs $0.15. Write an equation that could be used to solve for how many texts he would have to send for the Sprint plan to be the same as Verizon.
Answer:
y = 40 + 0.12x
y = 25 + 0.15x
Step-by-step explanation:
Hey Dylan! We're gonna use variable x to represent number of messages sent.
The $40 & $25 dollar payments won't be changed, so they can't have a variable applied to them.
Since it's 12 or 15 cents per text, that's where we wanna put the x.
Since both equations are equal to y, we can set them equal to each other.
40 + 0.12x = 25 + 0.15x
15 = 0.03x
x = 500 messages
Hope this helps! :)

If Jim spins the spinner 16 times, how many times would you predict the spinner to land on blue based on theoretical probability
Answer:
The answer is 4
Step-by-step explanation:
The experimental probability will be [tex]P =\dfrac{1}{8}[/tex]
What is experimental probability?
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

Can someone pls do these quick
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°.

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.

Brad is putting up a 10 foot radius circular flower garden in his yard. He will put plastic along the edge of the flowerbed. How many feet of plastic will Brad need to enclose his flower garden? (round to nearest hundredth) *
Answer:
314.16 ft²
Step-by-step explanation:
The flower garden is circular is shape.
To solve for this question, we have to find the area of the circular flower bed
The formula is given as
= πr²
Hence,
= π × 10²
= 314.15926536 ft²
Approximately = 314.16ft²
Therefore, 314.16ft² of plastic is needed

Answer:
288
Step-by-step explanation:
Does anyone know what the formula is?
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]
Help I need the answer dont send NO FILE only answer if you know it step by step explanation
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 !
