Mr. K was able to spot quite a few window washers on the skyscrapers there. He asked them how long it took to wash windows on such a building. They said that each person could wash 50 windows in 1 hour.
(How long would it take the 3 workers to wash all 1000 windows on one of the skyscrapers?)

Answers

Answer 1

Answer:

6.7 hours

Step-by-step explanation:

If one can do 50 then three can do 150.

So 1000÷150=6.66666666666

If a rectangular cross-section with coordinates at (1, 1), (1, 4), (3, 4) and (3, 1) is rotated about the line y = 1, what will be the resulting three-dimensional object?

Answers

Answer:

cylinder

Step-by-step explanation:

Answer

cylinder!!

Step-by-step explanation:

so the points "(1, 1), (1, 4), (3, 4) and (3, 1)" they are all positive so this makes this easier tbh so it looks like this once u put them on a grah

.        .

.        .

its a rectangle then it says to rotate on y = 1 which u look at the graph u just put this rectangle on its side like this

.               .

.               .

so then look at the answer options

A.) Cone

B.)Cylinder

C.)Sphere

D.)Pyramid

so it CANT be A bc 1 its a rectangle and if it was a cone it would have 3 points, not 4, bc it would be a triangle

It can be B bc on a graph it will be 2D and a Cylinder has 4 points on a graph(in 2D) which the problem is telling you to make something 2D into something 3D...and is a rectangle in 2D

It CANT be a C bc in 2D it would be a circle and straight up, a square isnt a circle, and the points on the problem is a square ant there would be so many points to put down if it was a circle

It CANT be a D bc once again this would be a triangle and that would have 3 points, or maybe 5(if your looking overhead of the Pyramid where u can see all 4 corners, like a square then the middle point) so a square has all equal sides, rectagle does not, it has 2 and 2 equal sides. 2 sides being small and paralell, and 2 long sides being parallel.

:) have a good day

btw answer is

cylinder!!

What is 12 - 33/4 equal in fraction form?

Answers

Answer:

3. 3/4

hope this helps

The expression 12 - (33/4) is equal to 15/4.

To express 12 - (33/4) as a fraction, we need to find a common denominator for the subtraction. The common denominator should be a multiple of 4, which is the denominator of (33/4).

We can rewrite 12 as an equivalent fraction with a denominator of 4:

12 = 48/4.

Now, we can rewrite the expression as:

48/4 - 33/4.

Since the denominators are the same, we can subtract the numerators directly:

(48 - 33) / 4 = 15/4.

Therefore, 12 - (33/4) is equal to 15/4.

In fraction form, the result is 15/4. This means that when we subtract 33/4 from 12, the answer can be represented as the fraction 15/4.

Graph the function y = 6 – 2x. Click the intercepts to show the coordinates.

Answers

Answer:

Step-by-step explanation:

Let's find and use the intercepts.  They speed up graphing of lines.

y-intercept:  In y = 6 – 2x, let x = 0.  Then y = 6, and the y-intercept is (0, 6).

x-intercept:  In y = 6 – 2x, let y = 0.  Then 2x = 6, and x = 3.  The x-intercept is therefore (3, 0).

Plot these two points and then draw a line through both.


Finding angle measures between intersecting lines

Answers

Answer:

x = 47°

Step-by-step explanation:

From the picture attached,

CPD is a straight line.

Therefore, ∠CPB and ∠DPB is a linear pair of angles.

And linear pair of angles are supplementary.

By the property of linear pair of angles,

m∠CPB + m∠DPB = 180°

133 + x = 180

x = 180 - 133

x = 47°

The two triangular prisms shown are similar. What is the volume of the larger prism? 36 m2 36 m3 144 m2 144 m3

Answers

Answer:

144 m^3

Step-by-step explanation:

Please find attached the image of the prisms

Volume of a triangular prism = area of the base x height  of the prism

Area of the base = 1/2 ( base x height)

the two prisms are similar, thus, the dimensions of the bigger rectangle can be gotten from the ratio of the base of the smaller and bigger triangle

ratio of their dimensions = 6 / 1.5 = 4

the dimensions of the bigger triangle is 4 times that of the smaller triangle

height of the base of the prism = 1.5 x 4 = 6

Height of the prism = 2 x 4 = 8

Area of the base of the prism = (1/2) x 6 x 6 = 18 m^2

Volume of the prism = 18 x 8 = 144 m^3

hopefully this makes sense.

The rotated triangle by 180° counterclockwise about the origin is [tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]

How to rotate the triangle?

The coordinates of the triangle are given as:

[tex]\left[\begin{array}{ccc}0&-3&5\\0&1&2\end{array}\right][/tex]

The rotation is given as:

180° counterclockwise about the origin.

The rule of 180° counterclockwise about the origin is:

(x,y) ⇒ (-x,-y)

Using the above rule, we have:

[tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]

Hence, the rotated triangle is [tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]
