here, we have.

given that,

Figure VWYX is a kite.

Sides V W and W Y are congruent, and sides V X and Y X are congruent.

Angles V and Y are right angles.

Angle W is (18 x minus 2) degrees and angle X is (12 x + 2) degrees.

The total of angles in any quadrilateral is 360°.

Angles V and Y are 90° each,

so the total of W and X must be 180°.

we have,

 (18x -2) +(12x +2) = 180

 30x = 180

 x = 180/30

    = 6

The value of x is 6.

Stefan sells Jin a bicycle for ​$115 and a helmet for ​$16. The total cost for Jin is ​%110 of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend​ originally? How much money did he make by selling the bicycle and helmet to​ Jin?

Answers

Answer:

The answer is below

Step-by-step explanation:

a)

Amount Stefan sold the bicycle and helmet to Jin = cost of bicycle + cost of helmet = $115 + $16 = $131

This amount that Jin bought both bicycle and helmet is 110% of what Stefan spent originally to buy the bike and helmet.

Let x = what Stefan spent originally to buy the bike and helmet = original price. Hence:

110% of x = $131

(110 / 100) * x = 131

1.1x = 131

x = $119.09

b)

Hence the profit made from selling the bike = $131 - $119.09 = $11.91

I REALLY NEED HELP!!!!!!!!!!!!

Answers

Answer: 64 centimeters squared.

Step-by-step explanation: This shape is a parallelogram. And the area of a parallelogram is just the base multiplied by the height. Here, the base is 10 cm and the height is 7 cm. So you might think the the area is just 70 centimeters squared. But here's the catch. There is a rectangular region in this parallelogram that is not shaded. But you can still easily solve this problem. All you need to do is find the area of that rectangular region and you already know the length and the width of this region. And, remember, the area of a rectangle is just the length and the width multiplied. So here, the area of that rectangular region is just 2 cm multiplied by 3 cm. Which will give you 6 centimeters squared. Now, all that's left to do is subtract the area of that rectangular region, 6 centimeters squared, from the total area of the parallelogram, 70 centimeters squared. And that should give you 64 centimeters squared as your final answer. I really hope this makes sense and is helpful.

a. The ratio between the lengths of two
pieces of lumber is 2:3. The longer piece is
21 ft long. How long is the shorter piece?




Help me please

Answers

Answer:

14 feet

Step-by-step explanation:

Let the shorter piece have length x.

Since the ratio is 2:3 and the longer piece is 21 feet long, we can write that as 2:3 = x:21.

Writing it as fractions, we get 2/3 = x/21 —(multiply by 21)—> x = 21*2/3 = 7*2 = 14 feet.

Thus, the shorter piece is 14 feet.

I hope this helps! :)

the shorter piece is 14ft long

Step-by-step explanation:

let the shorter piece be x

longer piece will be x:21

ratio of two pieces= 2:3

2:3=x:21

2/3=X/21

then cross multiply

21×2=3x

42/3=3x/3

X=14

2:3=14:21

Fred is making a fruit salad. The ratio of cups of peaches to cups of cherries is 2 to 3. How many cups of peaches will Fred need to make 60 cups of fruit salad? PLEASE GIVE A STEP BY STEP WAY TO FIND THE SOLUTION

Answers

Answer:

24 cups

Step-by-step explanation:

To find the amount of peaches in a fruit salad, you would multiply the cups of salad by 2/5 because 2 cups of peaches are dedicated to the fruit salad for every 3 cups of cherries, having the peaches make up 2 out of every 5 cups or 2/5. So the equation would be 60=0.4x, with x being the cups of peaches.

Answer:

40 Cups

Step-by-step explanation:

The number we want is 2/3 of 60. We need to multiply 2/3 by 60 which is 40. 40/60 is the new ratio of peaches to cherries, which is still 2/3. This way, we know we did it correctly.

To find:

The slope and its interpretation.

Solution:

Consider any two points from the table, i.e., (0,6) and (1,7).

The slope is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{7-6}{1-0}[/tex]

[tex]m=\dfrac{1}{1}[/tex]

Therefore, the slope is 1 and it represent that the number of tents made are increasing by 1 units in each hour.

A hiker travels at 2.8 miles per hour at a heading of N49°W from a ranger station. After 4 hours, how far north and how far west is the hike from the ranger station?

Answers

Answer:

Step-by-step explanation:

The diagram showing the pictorial view is attached below.

From the image, the distance of the hiker traveled which is denoted by "h" can be determined as follows:

h = 2.8 mi/hr × 4 hr

h = 11.2 mi

Using the trigonometric function;

The distance of how  far North is the hike from the ranger station can be determined by using the function of Sin θ

[tex]Sin \theta = \dfrac{opposite}{hypotenuse}[/tex]

[tex]Sin(41^0) = \dfrac{x}{11.2}[/tex]

x = Sin 41 (11.2)

x = 0.6561(11.2)

x = 7.34832

x ≅ 7.35 miles

The distance of how far west the hike from the ranger station is calculated by using:

[tex]cos \theta = \dfrac{adjacent}{hypotenuse}[/tex]

[tex]cos (41^0)= \dfrac{y}{11.2}[/tex]

y = 0.7547 × (11.2)

y = 8.45 miles

AB =

Answers

Answer:

The length of AB is 48 centimeters.

Step-by-step explanation:

According to the given information, AC is the hypotenuse of the right triangle, since it is opposed to a right angle (angle B). BC is the leg adjacent to angle B, whereas AB is the leg opposed to angle C. Then, we can find the length of AB by the following trigonometric identity:

[tex]\sin C = \frac{AB}{AC}[/tex] (1)

If we know that [tex]AC = 96\,cm[/tex] and [tex]C = 30^{\circ}[/tex], then the length of [tex]AB[/tex] is:

[tex]AB = AC\cdot \sin C[/tex]

[tex]AB = (96\,cm) \cdot \sin 30^{\circ}[/tex]

[tex]AB = 48\,cm[/tex]

The length of AB is 48 centimeters.
