Given the following equilateral triangle,what is X?

Answer: 300 yards

Step-by-step explanation:

Since b1 is equal to 14 yds and b2 is equal to 26 yds we can plug that into the equation below (in the image).

b1 + b2 = 14 + 26 = 40 yards

Now that we have found (b1 + b2), you can multiply that by h (the height of the trapezoid) which is 15, so we get 40 x 15 = 600.

In a lot of area equations, you will have to divide by two like in the trapezoid equation. Divide our number (600) by 2, so we get 600 ÷ 2 = 300.

300 yds is your final answer.

Hope this helps!

Answer: 901 students are left

Answer:

This is not a function.

Step-by-step explanation:

Note, that set A contains 3 elements that only map to 2 elements in set B.  A function would require that each element of set A to match to only one element of set B.

Since set B contains an element with no mapping to an element in set A, this does not represent a function.

Answer: $263

Step-by-step explanation:

From the question, we are informed that Monday, a restaurant made $545 by selling 110 hamburgers. This means that one hamburger costs:

= $545/110

= $4.955

Therefore, 53 hamburgers will cost:

= 53 × $4.955

= $262.62

= $263 approximately

Answer:

Francis Drake was born in the UK and he's a naval officer

Step-by-step explanation:

Drake is most famously known for his circumnavigation of the world in a single expedition, from 1577 to 1580, and was the first to complete the voyage as captain while leading the expedition throughout the entire circumnavigation. He discovered that Tierra del Fuego, the land south of the Magellan Strait, was not another continent as Europeans believed, but instead a group of islands. This meant that ships could sail between the Atlantic and Pacific oceans around the bottom of South America (later known as the Cape Horn route).

Answer:

The center is ( 5.3, -3.3) and 7 is the radius

Step-by-step explanation:

We can write the equation of a circle as

( x-h)^2 + ( y-k)^2 = r^2

Where ( h,k) is the center and r is the radius

(x - 5.3)^2 + (y + 3.3)^2=49

(x - 5.3)^2 + (y -  -3.3)^2=7^2

The center is ( 5.3, -3.3) and 7 is the radius

Answer:

2830.6875 hours of sleep per year (7.45 should be 7.75)

Step-by-step explanation:

To find your average sleep per year, you need to covert avg hours per day, to days per year.

Note that 45 minutes is not equivalent to .45 hours, but actually .75 hours since there are only 60 minutes in an hour.  ( 45 / 60 == .75 )

Simply, the amount of days per year is 365.25 (to account for leap years).

So perform this calculation:

(7.75 hrs / day ) * ( 365.25 days / year ) == 2830.6875 hrs / year

Meaning, on average you get 2830.6875 hours of sleep per year.

Answer:

The correct option is J.II, III, IV and V only.

Step-by-step explanation:

A rational number are those numbers that can shown in a p/q form or as the ratio of two numbers.

The numbers that cannot be shown as the ratio of two numbers are known as irrational.

Consider each number at a time:

[tex]\sqrt{49} =7\equiv 7:1[/tex]

[tex]0.287=\frac{287}{1000}[/tex]

[tex]\sqrt{\frac{9}{16}}=\frac{3}{4}\equiv 3:4[/tex]

[tex]25\equiv 25:1[/tex]

Thus, the numbers that are rational are II, III, IV and V.

The correct option is J.

Step-by-step explanation:

The wind has a speed of w and a direction α with the vertical.  The x component of that speed is w sin α.  The y component is -w cos α.

In order to stay on the north trajectory AB, the plane must have a horizontal speed of -w sin α.  The plane's speed is v, so using Pythagorean theorem, the y component of the plane's speed is:

v² = (-w sin α)² + vᵧ²

v² = w² sin²α + vᵧ²

vᵧ = √(v² − w² sin²α)

The total vertical speed is therefore √(v² − w² sin²α) − w cos α.

If a is the length of AB, then the time is:

t = a / [√(v² − w² sin²α) − w cos α]

To rationalize the denominator, we multiply by the conjugate.

t = a / [√(v² − w² sin²α) − w cos α] × [√(v² − w² sin²α) + w cos α] / [√(v² − w² sin²α) + w cos α]

t = a [√(v² − w² sin²α) + w cos α] / (v² − w² sin²α − w² cos²α)

t = a [√(v² − w² sin²α) + w cos α] / (v² − w²)

Answer:

[tex] m\angle XVW = 100\degree[/tex]

Step-by-step explanation:

In the first figure, FP is the bisector of [tex] \angle DFE[/tex]

[tex] \therefore m\angle 1 = m\angle 2\\

\therefore 44x + 1 = 46x - 1\\

\therefore 1 + 1 = 46x - 44x\\

\therefore 2 = 2x\\

\therefore \frac{2}{2} = x \\

\huge \red {\boxed {\therefore x = 1}} [/tex]

In the second figure, VP is the bisector of [tex] \angle XVW[/tex]

[tex] \therefore m\angle 1 = m\angle 2\\

\therefore 12x + 2 = 11x +6\\

\therefore 12x - 11x = 6 - 2\\

\therefore x = 4\\

\because m\angle XVW = m\angle1 + m\angle 2\\

\therefore m\angle XVW = 12x + 2 + 11x +6\\

\therefore m\angle XVW = 23x + 8\\

\therefore m\angle XVW = 23\times 4+ 8\\

\therefore m\angle XVW = 92+ 8\\

\huge \purple {\boxed {\therefore m\angle XVW = 100\degree}} \\

Answer:

[tex]P(T\ n\ S) = \frac{1}{14}[/tex]

Step-by-step explanation:

*Missing Part of the Question*

4 stars

5 triangles

3 circles

3 squares

Required

Determine the probability of triangle being first then square being second

[tex]Total = 4 + 5 + 3 + 3[/tex]

[tex]Total = 15[/tex]

Represent the triangle with T and square with S

So, we're solving for P(T n S)

[tex]P(T\ n\ S) = P(T) * P(S)[/tex]

Solving for P(T)

[tex]P(T) = \frac{n(T)}{Total}[/tex]

[tex]P(T) = \frac{5}{15}[/tex]

Solving for P(S)

The question implies a probability without replacement;

Hence Total has now been reduced by 1

Total = 14

[tex]P(S) = \frac{n(S)}{Total}[/tex]

[tex]P(S) = \frac{3}{14}[/tex]

Recall that

[tex]P(T\ n\ S) = P(T) * P(S)[/tex]

[tex]P(T\ n\ S) = \frac{5}{15} * \frac{3}{14}[/tex]

[tex]P(T\ n\ S) = \frac{15}{15 * 14}[/tex]

[tex]P(T\ n\ S) = \frac{1}{14}[/tex]

Hence, the required probability is

[tex]P(T\ n\ S) = \frac{1}{14}[/tex]

Answer:

Answer:

x=4

Step-by-step explanation:

Realize that a function can only have one output, y, for each unique input, x.

2 Methods on finding if something is a function or not.

Do the vertical function test

To use the vertical line test, take a ruler or other straight edge and draw a line parallel to the y-axis for any chosen value of x. If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function.

Plug in points! See if there are more than one outputs for y

====================================================

Explanation:

See the diagram below. We're looking for the area of the shaded region in blue.

This is known as an inscribed circle since the circle is inside the square, touching each side at one point. This circle is as large as possible without spilling outside the square. Think of a balloon that has been inflated as much as possible to fill the room (it touches every wall at a tangent point).

The square has area s^2 = 6^2 = 6*6 = 36 square inches.

The circle has area pi*r^2 = pi*3^2 = 9pi square inches exactly. Note how I cut the diameter (6) in half to get the radius (3).

The blue shaded area is the difference of the square and circle areas, so we have 36 - 9pi as the exact area of the shaded region.

Using your calculator, you should find that 36-9pi = 7.72566611769187 approximately. I'm using my calculator's stored version of pi as opposed to something like pi = 3.14; but you may need to ask your teacher for clarification about what version of pi to use.

When rounding to the nearest tenth, we then get roughly 7.7 square inches as our final answer.

The surface area of the given right cylinder is 252π square units. Therefore, option D is the correct answer.

The surface area of a cylinder refers to the total area that the cylinder's curved surface and circular bases cover. The total surface area of the cylinder includes the area of the 2 bases of the cylinder (each of which is in the shape of a circle) and the area of the curved surface.

Given that, the radius of a cylinder is 6 units and the height of a cylinder is 15 units.

We know that, the total surface area of a cylinder is 2πr(r + h).

Now, the surface area = 2×π×6(6+15)

= 2×π×6×21

= 252π square units

Therefore, option D is the correct answer.

Answer:

The width is 16 cm

Step-by-step explanation:

The perimeter of a rectangle=28 cm

length=8cm

width=?

P=28

=L+W

=8+8=16

=6+6=12

=16+12

=28 cm

Therefore, the width is 6+6=16 cm

Hope it helps you!!

Answer: 12

Step-by-step explanation: the length is 8 cm so, times that by 2 because there are 2 lengths which makes it 16cm. Now you subtract 16 from the 28cm which is 12cm divide this by 2 because there are two widths this equals 6 cm

Therefore; our width is 6 cm

To check if this is right you can add all the values= 8+8+6+6= 28cm
