Word problem: 40% of the Ipads have built-in wifi. If there are 400 Ipads, how
many have built-in wifi?

Given:

The diagram.

To find:

(a) [tex]m\angle SQT[/tex]

(b) [tex]m\angle QRW[/tex]

(c) [tex]m\angle PRV[/tex]

Solution:

(a)

If two lines intersect each other at a point, then the vertically opposite angles are equal.

[tex]m\angle SQT = m\angle PQR[/tex]          (Vertically opposite angles)

[tex]m\angle SQT = 36^\circ[/tex]

Therefore, the measure of angle SQT is 36 degrees.

(b)

If a transversal line intersect two parallel lines, then the alternate interior angles are equal.

[tex]m\angle QRW = m\angle PQR[/tex]       (Alternate interior angles)

[tex]m\angle QRW = 36^\circ[/tex]

Therefore, the measure of angle QRW is 36 degrees.

(c)

It is given that the angles PRV and angle PRQ are congruent.

Let the measures of angle PRV and angle PRQ are x degrees.

[tex]m\angle PRV+m\angle PRQ+m\angle PQR=180^\circ[/tex]      (Adjacent interior angles are supplementary)

[tex]x+x+36^\circ=180^\circ[/tex]

[tex]2x=180^\circ -36^\circ[/tex]

[tex]2x=144^\circ[/tex]

Divide both sides by 2.

[tex]x=\dfrac{144^\circ}{2}[/tex]

[tex]x=72^\circ[/tex]

Therefore, the measure of angle PRV is 72 degrees.

Step-by-step explanation:

Answer:

Y = 16a + 12b

Step-by-step explanation:

Given:

Cost of each neckless = $16

Cost of each bracelet = $12

Find:

Equation for the following state

Computation:

Assume;

Number of neckless sale in a month = a

Number of bracelet sale in a month = b

Total amount she earn = Y

So,

Total amount she earn = (Cost of each neckless)(Number of neckless sale in a month) + (Cost of each bracelet)(Number of bracelet sale in a month)

Y = (16)(a) + (12)(b)

Y = 16a + 12b

Answer:

This question has incorrect answers but the answer that they are looking for is: 24 hours

Step-by-step explanation:

The average is the total hours divided by the number of weeks

So far Emily has 6 hours for the first 3 weeks, x is the number of hours she needs to work in the 4th week.  

(6+x)/4=10

6+x = 40

x = 34

All the answers they gave are wrong because they did not account for the 4th week while taking averages.

Answer:

D

Step-by-step explanation:

in order to get the process of solving the equation, we need to solve it.

our goal to solve the equation 6x-19=77 is to isolate the variable onto one side, and have the numbers (value of x) on the other

we have the equation:

6x-19=77

first, we can get rid of -19 on the left side and leave 6x on that side by adding 19 to both sides (-19+19=0).

The reason why we're adding 19 to both sides is because if we do something to one side, we have to do it to the other side to make sure the value of the equation stays the same.

6x-19= 77

   +19  +19

_________

6x=96

now, we do have the variables on one side and the numbers on another side, but we aren't done yet, as we want the value of x by itself

divide by 6 on both sides

x=16 (because 6x/6=1x, or x. 96/6=16).

the option of D shows the same method I did and has the correct answer as well.

This is what was given for D:

6x-19=77

6x-19+19=77+19

6x=96

6x/6=96/6

x=16

(same thing I did)

So D is the correct answer.

Hope this helps!

The construction is missing, so i have attached it.

Answer:

Use the incenter to determine the center to construct the circle.

Step-by-step explanation:

From the attached image, we can see that the 3 bisector of the three interior angles in the triangle intersect at a point. This point is known as the incentre of the triangle.

Now, to draw an inscribed circle inside the triangle, we will draw a perpendicular line from the incentre to any of the 3 sides and we will use the incentre as centre to draw the circle to touch each of the 3 perpendicular points.

Answer:

The answer is D. 8/17

Step-by-step explanation:

We know, sin= opposite/hypotenuse

So as Θ is referring to Angle L

∴ sin Θ = 8/17

The total distance that Jacob and his dad hiked from their campsite to the top of the mountain is approximately 7,105.92 feet.

To calculate the total distance Jacob and his dad hiked from their campsite to the top of the mountain, we need to consider the width of the base of the mountain and the height of the mountain.

Given:

Base width of the mountain: 2,600 feet

Since the mountain is pretty much isosceles, we can assume that the height of the mountain is equal to the length of the two equal sides of the triangle formed.

To find the height of the mountain, we can use the Pythagorean theorem.

Let's assume the height of the mountain is 'h' feet.

Using the Pythagorean theorem, we have:

[tex](2,600/2)^2 + h^2 = 2,600^2[/tex]

Simplifying the equation:

[tex]1,300^2 + h^2 = 2,600^2\\1,690,000 + h^2 = 6,760,000[/tex]

[tex]h^2 = 6,760,000 - 1,690,000\\h^2 = 5,070,000[/tex]

Taking the square root of both sides:

h = sqrt(5,070,000)

h ≈ 2,252.96 feet

Now we can calculate the total distance they hiked from their campsite to the top of the mountain by considering the base width and the height of the mountain.

Total distance = Base width + 2 × Height

Total distance = 2,600 + 2 × 2,252.96

Total distance ≈ 2,600 + 4,505.92

Total distance ≈ 7,105.92 feet

Therefore, the total distance that Jacob and his dad hiked from their campsite to the top of the mountain is approximately 7,105.92 feet.

Step-by-step explanation:

Ah...right triangle trig. Gotta love this stuff (you better, because it never goes away!). We need to remember SohCahToa which tells us that the sin of an angle is equal to the side opposite the angle over the hypotenuse; the cos of an angle is equal to the side adjacent to the angle over the hypotenuse; the tan of an angle is equal to the side opposite the angle over the side adjacent the angle. x is the side across from our given angle, while 7 is the side adjacent. That means that we will use the tangent ratio to solve.

Step-by-step explanation:

Angle A in triangle ABC is approximately 76 degrees. So, correct option is A.

In a right triangle, the side opposite the right angle is called the hypotenuse, and the other two sides are called the legs. Let's consider triangle ABC, where angle B is the right angle, AC is the hypotenuse, and BC is one of the legs.

We are given that AC = 33 and BC = 32. To find angle A, we can use trigonometric ratios. In this case, we can use the sine function.

The sine of angle A is defined as the ratio of the length of the side opposite angle A (BC) to the length of the hypotenuse (AC):

sin(A) = BC / AC

Substituting the given values, we have:

sin(A) = 32 / 33

Using the inverse sine function (sin⁻¹), we can find the value of angle A:

A = sin⁻¹(32 / 33)

Using a calculator, we find that angle A is approximately 75.85 degrees. Rounding off to the nearest angle we get 76 degrees.

Therefore, angle A in triangle ABC is approximately 76 degrees. So, correct option is A.

Answer: 24 in2

Step-by-step explanation:

The square pyramid has a surface area of 24 square miles.

The area or region that an object’s surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has. There are numerous shapes and dimensions in geometry, including spheres, cubes, cuboids, cones, cylinders, etc. Each form has its own volume and surface area.

The surface area of a square pyramid is given by the formula:

[tex]S = L^2 + 2L\sqrt{((L/2)^2 + H^2)[/tex]

where L is the length of the base, H is the height of the pyramid, and S is the surface area.

Given L = 2 mi and slant height = 5 mi, we need to find H.

Using the Pythagorean theorem, we can find H as follows:

[tex]H^2 = (slant\ height)^2 - (1/2 L)^2\\\\H^2 = 25 - 1\\\\\H^2 = 24\\\\H = \sqrt{24[/tex]

Now, we can plug in the values of L and H into the formula for surface area:

[tex]S = L^2 + 2L\sqrt{((L/2)^2 + H^2)} \\\\S = 2^2 + 2(2)\sqrt{((2/2)^2 + (\sqrt{24})^2)}\\\\S = 4 + 4\sqrt{(1 + 24)}\\\\S = 4 + 4\sqrt{25}\\\\S = 4 + 4(5)\\\\S = 24[/tex]

Therefore, the surface area of the square pyramid is 24 square miles.
