Answer:

22.5 miles per hour

Step-by-step explanation:

Given system of equations

5(s-w)=900

4(s+w)=900

Set equations equal to each other

5(s-w)=4(s+w)

5s-5w=4s+4w

s-5w=4w

s=9w

Solve for w using the substitution s=9w

4(s+w)=900

4(9w+w)=900

4(10w)=900

40w=900

w=22.5

Therefore, the speed of the wind is 22.5 miles per hour

Answer:

The Area of the composite figure would be 76.26 in^2

Step-by-step explanation:

According to the Figure Given:

Total Horizontal Distance = 14 in

Length = 6 in

To Find :

The Area of the composite figure

Solution:

Firstly we need to find the area of Rectangular part.

So We know that,

[tex]\boxed{ \rm \: Area \: of \: Rectangle = Length×Breadth}[/tex]

Here, Length is 6 in but the breadth is unknown.

To Find out the breadth, we’ll use this formula:

[tex] \boxed{\rm \: Breadth = total \: distance - Radius}[/tex]

According to the Figure, we can see one side of a rectangle and radius of the circle are common, hence,

[tex] \longrightarrow\rm \: Length \: of \: the \: circle = Radius[/tex]

[tex]\longrightarrow \rm \: 6 \: in = radius[/tex]

Hence Radius is 6 in.

So Substitute the value of Total distance and Radius:

[tex] \longrightarrow\rm \: Breadth = 14-6[/tex]

[tex] \longrightarrow\rm \: Breadth = 8 \: in[/tex]

Hence, the Breadth is 8 in.

Then, Substitute the values of Length and Breadth in the formula of Rectangle :

[tex] \longrightarrow\rm \: Area \: of \: Rectangle = 6 \times 8[/tex]

[tex]\longrightarrow \rm \: Area \: of \: Rectangle = 48 \: in {}^{2} [/tex]

Then, We need to find the area of Quarter circle :

We know that,

[tex]\boxed{\rm Area_{(Quarter \; Circle) } = \cfrac{\pi{r} {}^{2} }{4}} [/tex]

Now Substitute their values:

[tex]\longrightarrow\rm Area_{(Quarter \; Circle) } = \cfrac{3.14 \times 6 {}^{2} }{4} [/tex]

Solve it.

[tex]\longrightarrow\rm Area_{(Quarter \; Circle) } = \cfrac{3.14 \times 36}{4} [/tex]

[tex]\longrightarrow\rm Area_{(Quarter \; Circle) } = \cfrac{3.14 \times \cancel{{36} } \: ^{9} }{ \cancel4} [/tex]

[tex]\longrightarrow\rm Area_{(Quarter \; Circle)} =3.14 \times 9[/tex]

[tex]\longrightarrow\rm Area_{(Quarter \; Circle) } = 28.26 \: {in}^{2} [/tex]

Now we can Find out the total Area of composite figure:

We know that,

[tex]\boxed{ \rm \: Area_{(Composite Figure)} =Area_{(rectangle)}+ Area_{ (Quarter Circle)}}[/tex]

So Substitute their values:

[tex]\longrightarrow \rm \: Area_{(Composite Figure)} =48 + 28 .26[/tex]

Solve it.

[tex]\longrightarrow \rm \: Area_{(Composite Figure)} =\boxed{\tt 76.26 \:\rm in {}^{2}} [/tex]

Hence, the area of the composite figure would be 76.26 in² or 76.26 sq. in.

Answer:

x = 4√2

Step-by-step explanation:

x² - 33 = -1            [ change sides ]

x² = -1 + 33          

x² = 32

x = √3   [changing sides, changes power of square, (²) turns square root,√ ]

x = √4 * 4 * 2

x = 4√2   .......final answer.

Answer:

x = 4√2 or x = −4√2

Step-by-step explanation:

Step 1: Add 33 to both sides.

x2 − 33 + 33 = −1 + 33

x2 = 32

Step 2: Take square root.

x = ±√32

x = 4√2 or x = −4√2

Answer:

Step-by-step explanation:

This is the Pythagorean theorem:
[tex]a^{2} +b^{2} =c^{2}[/tex]
The hypotenuse is c so we need to make c the subject:
[tex]c = \sqrt{a^{2}+b^{2} }[/tex]
To do this I simply square rooted both sides.
Now we substitute values given to get the answer of the hypotenuse:
[tex]c = \sqrt{3^{2} + 4^{2} }[/tex]
[tex]c = \sqrt{9+16}[/tex]
[tex]c = \sqrt{25}[/tex]

There are 8 laser beams.

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagorean theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

The length of the laser beams is the addition of the segments AD to segment CB (which are equal).

Using Pythagoras theorem in ECD

ED² = EC² + CD²

ED= √(12² + 35²)

ED = √144 + 1225

ED = 37 unit

Again In Triangle AED

AD² = EA² + ED²

AD=√15² + 37²

AD = 40 unit

Then, there are total of 80 ft of laser beams.

Picture example:

Answer:

A) 2/3, -3/4, 1/2, -1/3

Start by making all of them have the same denominator. They all multiply to 12 easily, so I will use that. Remember that whatever you do to the top you have to do to the bottom, and vice versa.

Multiply 2/3 by 4/4 to get 8/12

Multiply -3/4 by 3/3 to get -9/12

Multiply 1/2 by 6/6 to get 6/12

Multiply -1/3 by 4/4 to get -4/12

Least to greatest (new): -9/12, -4/12, 6/12, 8/12

Least to greatest (old): -3/4, -1/3, 1/2, 2/3 <-------- this is your answer

C) -9/10, -8/9, -4/5, -41/45

Make them have the same denominator. They all multiply to 90, so I'll use that.

Multiply -9/10 by 9/9 to get -81/90

Multiply -8/9 by 10/10 to get -80/90

Multiply -4/5 by 18/18 to get -72/90

Multiply -41/45 by 2/2 to get -82/90

Least to greatest (new): -82/90, -81/90, -80/90, -72/90

Least to greatest (old): -41/45, -9/10, -8/9, -4/5 <-------- this is your answer

E) -3, -2 2/3, -3 1/6, 2 3/4

Make the mixed numbers into improper fractions by multiplying the whole number with the denominator, and then adding the numerator:

-3 ---> -3/1 (this one's easy)

-2 2/3 ---> -8/3

-3 1/6 ---> -19/6

2 3/4 ---> 11/4 (this one is the only positive one, so it will be the greatest)

Same denominator. I'm using 12.

Multiply -3/1 by 12/12 to get -36/12

Multiply -8/3 by 4/4 to get -32/12

Multiply -19/6 by 2/2 to get -38/12

Multiply 11/4 by 3/3 to get 33/12

Least to greatest (new): -38/12, -36/12, -32/12, 33/12

Least to greatest (old): -3 1/6, -3, -2 2/3, 2 3/4 <-------- this is your answer

Answer:

[tex]cos\theta=\frac{3}{5}[/tex]

Step-by-step explanation:

Since [tex]sin\theta=0.8[/tex] is the same as [tex]sin\theta=\frac{4}{5}[/tex] and [tex]sin\theta=\frac{opposite}{hypotenuse}[/tex], then we know that the side opposite to the angle [tex]\theta[/tex] is 4 units and the hypotenuse is 5 units.

Because [tex]cos\theta=\frac{adjacent}{hypotenuse}[/tex], then we have to find the adjacent side to the angle [tex]\theta[/tex] using the Pythagorean Theorem:

[tex]a^2+b^2=c^2\\\\(adjacent)^2+(opposite)^2=(hypotenuse)^2\\\\(adjacent)^2+4^2=5^2\\\\(adjacent)^2+16=25\\\\(adjacent)^2=9\\\\adjacent=3[/tex]

Therefore, since the adjacent side is 3 units, then [tex]cos\theta=\frac{3}{5}[/tex]

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

Explanation:

In a standard deck, there are 52 cards.

If this deck is missing the queen of hearts and 2 of clubs, then we really have 52-2 = 50 cards in the deck.

There are 4 aces and 13 spades. Those values add to 4+13 = 17, but we need to subtract off 1 to account for the ace of spades counted twice. We have 17-1 = 16 cards that are either an ace, a spade, or both.

Or you can think of it like saying 13 spades + 1 ace of hearts + 1 ace of diamonds + 1 ace of clubs = 16 cards total.

-----------------

The event space has A = 16 cards in it, while the sample space has B = 50 cards.

The probability we're after is A/B = 16/50 = 8/25

Carla would have about 795 pictures on May 16th.

A linear equation is in the form:

y = mx + b

where y,x are variables, m is the rate of change and b is the y intercept.

Let y represent the number of pictures after x days.

At April 30th, Carla sees that she has 235 pictures, hence b = 235. Also,  she takes 35 pictures each day, hence m = 35. The equation is:

y = 35x + 235

On May 16th, x = 16 hence:

y = 35(16) + 235 = 795

Explanation:

AB = AX+XB = 8+22 = 30

The ratio of AB to AX is AB/AX = 30/8 = 3.75

AC = AY+YC = 9+33 = 42

The ratio of AC to AY is AC/AY = 42/9 = 4.67 approximately

Since we don't get the same result, this means that the equation AB/AX = AC/AY is not true. The sides are not in proportion with one another, and therefore the triangles aren't similar.

The sides need to be in proportion with one another so we could use the SAS similarity rule.

Considering the SAS similarity theorem, triangles ABC and AXY are not similar triangles.

The SAS Similarity postulate or theorem, states that, when two triangles have two pairs of corresponding sides whose ratios are the same, and also has a pair congruent included angles, then, both triangles are similar.

Triangles ABC and AXY have a pair of congruent included angles, ∠BAC ≅ XAY.

Let's find out if their corresponding sides have equal ratios.

Thus:

AB/AX = 30/8 = 3.75

AC/AY = 42/9 = 4.67

Their ratios are not equal.

Therefore, considering the SAS similarity theorem, triangles ABC and AXY are not similar triangles.

Answer:

The x -intercept is (3, 0)

The y -intercept is (0, - 2)

Step-by-step explanation:

Given equation is: -6x + 9y = -18

To find x - intercept:

Plug y = 0 in the given equation.

-6x + 9(0) = - 18

-6x + 0 = -18

-6x = - 18

x = (-18)/(-6)

x = 3

The x -intercept is (3, 0)

To find y - intercept:

Plug x = 0 in the given equation.

-6(0) + 9y= - 18

0 + 9y = -18

9y = - 18

y = (-18)/(9)

y = - 2

The y -intercept is (0, - 2)
