Answers

Answer:

x = 8

z = 15

y = 118°

Step-by-step explanation:

First, we know that these are similar. That means that if we know which angles correspond to each other, those are equal, and the sides that correspond to each other have a common ratio. I went ahead and rotated PQRS so that it visually aligns with WXYZ -- that image is attached. We can do this because similar shapes must have the same angles, so aligning the angles works here. Using that, we can see that, based on the angles, QR matches up with XY, WZ matches up with PS, and so on.

We can then say that there is a common ratio between the corresponding sides.

WZ/PS = XW/PQ = ZY/RS = 9/6 = 12/x = z/10

9/6 simplifies to 3/2, so we have

3/2 = 12/x

multiply both sides by x to no longer have it as a denominator

3 * x / 2 = 12

multiply both sides by 2 and divide both sides by 3 to isolate x

x = 8

3/2 = z / 10

multiply both sides by 10 to isolate z

z = 15

In the corresponding figures, we can see that y matches up with ∠WXY. Thus, the two angles are equal and y = 118°

In a survey of 200 people who visited China, 85% visited the Great Wall. Of those who visited the Great Wall, 30% also visited the Chengdu Panda Center. Of those who did not visit the Great Wall, 80% visited the Panda Center.Enter the correct answers in the boxes to complete the two-way frequency table.

Answers

Based on the percentages given on those who visited the Great Wall, the relative frequencies will show the following?

People who visited Great Wall - 170 people.People who visited the Chengdu Panda Center - 51 people.People who visited Panda Center - 24 people.

How many people visited the Great Wall?

The number of people who went to Great Wall was:

= 200 x 85%

= 170 people

How many people visited the Chengdu Panda Center?

= Number of people who went to Great Wall x 30%

= 170 x 30%

= 51 people

How many people visited Panda Center?

= (1 - 85%) x Number of people surveyed x 80%

= 0.15 x 200 x 80%

eduardo has 4 1/2 yard of rope light. Exactly how many more yard does he need to finish the car's ceiling

Answers

Answer:

2 1/6

Step-by-step explanation:

Because the denominators are different, and there are whole numbers involved, then first make the fractions improper.

4 1/2 -> 9/2

6 2/3 -> 20/3

Next, make the denominators the same by multiplying each fraction by the denominator of the other.

9/2 * 3 = 27/6

20/3 * 2 = 40/6

Then you can subtract the numerators because the denominators are the same:

40/6-27/6= 13/6

Then you can convert to a mixed fraction if need be.

For f(x) = x2 and g(x) = (x - 5)2, in which direction and by how many units should f(x) be shifted to obtain g(x)? (5 points)
O Right 5 units
Up 5 units
Left 5 units
Down 5 units

Answers

Answer:

right 5 units

Step-by-step explanation:

given f(x) then f(x ± a) is a horizontal translation of f(x)

• if + a then a shift of a units left

• if - a then a shift of 5 units right

f(x) → g(x) = (x - 5)² with a = - 5

then f(x) is shifted 5 units right to obtain g(x)

An equilateral triangle (all 3 sides are the same length) sits on top of a square. They both share the side AB

Answers

Answer:

6x +15

Step-by-step explanation:

To solve for the perimeter of the triangle, we need to find the length of each side.

(a +b)² = a² +2ab +b²

Let's factorise the expression for the area of the square:

Area of square

= 4x² +20x +25

= (2x +5)²

Since area of square= side ×side, length of a side of the square is the square root of its area. We are also given that the side of the square is AB.

(AB)²= (2x +5)²

Taking the square root of both sides:

AB= 2x +5

The perimeter is the sum of the lengths of all of its sides.

Perimeter of the triangle

= 3(AB)

= 3(2x +5)

= 6x +15

Answer:

Step-by-step explanation:

What speed will a fan turn if the drive motor is turning at 1250 RPM, the motor pulley is 4 inches in diameter, and the fan pulley is 8 inches in diameter

Answers

The speed the fan will turn is 625 rpm

Linear speed

Since they fan and the pulley ahve the same linear speed v = rω where

r = radius of pulley and ω = angular speed.

Then

r₁ω₁ = r₂ω₂ where

r₁ = radius of fan pulley = 8 in/2 = 4 in, ω₁ = angular speed of fan pulley, r₂ = radius of motor pulley = 4 in/2 = 2 in, ω₂ = angular speed of motor pulley = 1250 rpm

Angular speed of fan pulley

Making ω₁ subject of the formula, we have

ω₁ = r₂ω₂/r₁

Substituting the values of the variables into the equation, we have

ω₁ = r₂ω₂/r₁

ω₁ = 2 in × 1250 rpm/4 in

ω₁ = 1250 rpm/2

ω₁ = 625 rpm

So, the speed the fan will turn is 625 rpm

I don't understand this
the box is in the shape of a cuboid.
height: 60cm
length: 100cm
width: 40cm
Joh wants to fill the box with grit.
A bag of grit costs £2.50
there are 8000cm^3 of grit in a bag.
Joh has £70 to spend on the grit.
Does John have enough money to buy all the grit he needs to fill the box completely?

Answers

We calculate the volume of the cuboid :

60 x 100 x 40 = 240000 cm^3

If every bag has 8000 cm^3 of grit, he will need 240000 : 8000 = 30 bags

Every bag cost £2.50, so he will need £2.50 x 30 = £75

Since he only has £70, he doesn't have enough money to buy the grit.

The length of a rectangle is 5m longer than the width. The perimeter of the rectangle is 82m. Find the length and width of the rectangle.​

Answers

Answer:

length: 23 mwidth: 18 m

Step-by-step explanation:

The given dimensions are related by the perimeter formula for a rectangle.

Let w represent the width in meters. Then (w+5) represents the length. These values can be put into the perimeter formula, which can be solved to find w.

  P = 2(L +W)

  82 = 2((w+5) +w) . . . . fill in for L and W

  41 = 2w +5 . . . . . . . . divide by 2

  36 = 2w . . . . . . . . . subtract 5

  18 = w . . . . . . . . . divide by 2. This is the width.

  w+5 = 18+5 = 23 . . . . find the length

The length of the rectangle is 23 m; the width is 18 m.
