Ellie buys a mobile phone in Spain for €352.50
Her brother jack buys an identical phone in Japan for ¥39856 (Japanese Yen)
Using the exchange rate below:
£1= €1.41
£1= ¥188
A) Decide in which county is the mobile phone cheaper

B) Workout by how much (in £).

Answers

Answer:

A Japan and B £38

Step-by-step explanation:

Spain £1=€1.41

more €352.50

€352.50÷1.41 ×1 = £250

Japan £1= ¥188

more ¥39856

¥39856÷188×1 =£212

A) Japan is cheaper

B) £250-£212=£38

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°.

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.

Does anyone know what the formula is? ​

Answers

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]

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.

Answers

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! :)

total of 73.6 pounds of clay and glass to make the bowls. Each bowl contains how many pounds of glass? If you can show your work that would be awesome

Answers

Easy. You take 73.6 and subtract it by 59.2.
73.6 - 59.2 = 14.4. Explaination: Because there is 59.2 pounds of clay in all of 73.6, you subtract 73.6 by 59.2.

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.
