Answer:

Alexis will wash 14 windows in 1 hour.

Step-by-step explanation:

We are given the following information in the question.

Number of windows washed = 10\displaystyle\frac{1}{2}

Time taken to wash the windows = \displaystyle\frac{3}{4} \text{ hours}

We have to find:

Number of windows washed in 1 hour=

Formula:

\text{Windows washed in 1 hour} = \displaystyle\frac{\text{Total windows washed}}{\text{Time taken to wash windows}}=\frac{10\frac{1}{2}}{\frac{3}{4}}\\\\=\frac{21\times 4}{3\times 2} = 14

Thus, Alexis will wash 14 windows in 1 hour.

The sum of the lengths of any two sides of a triangle must be greater than the third side. If a triangle has one side that is 18
kogti [31]

Answer: One side could be 18 and the other side will be 33.

Step-by-step explanation:

  • Side #1 = 18
  • Side #2 = 2x - 3
  • Side #3 = x

<u>One way of setting up the inequality is: Side #2 + Side #3 > Side #1</u>

<u />2x-3+x>18\\3x-3>18\\3x>18+3\\3x>21\\x>7

<u>Another way of setting up the inequality is: Side #1 + Side #3 > Side #2</u>

<u />18+x>2x-3\\18+3>2x-x\\x<u />

<u>Final way of setting up the inequality is: Side #1 + Side #2 > Side #3</u>

<u />18+2x-3>x\\15>x-2x\\15>-x\\x>-15<em />

<em>Therefore, we have the range for our value of x, which is between 7 and 21. Any possible value between works. Negative measurements are rejected. One of the sides would equal the x-value, while the other side would equal the value of 2x-3.</em>

PLEASE HELP! (04.02 MC) Write an equation of a line parallel to line EF in slope-intercept form that passes through the point (2
Tanya [424]

Answer:

  C.  y = -2/3x +22/3

Step-by-step explanation:

You can choose the correct answer by realizing that the line must have a y-intercept greater than 6. The given point is (2, 6) and the line goes up and to the left from there. The y-intercept is obviously more than 6.

The only reasonable answer choice is ...

  y = -2/3x +22/3 . . . . . a y-intercept of 7 1/3

_____

There are a lot of ways to work problems like these. One is to write the equation of the line, then match that to the answer choices.

Another is to eliminate all the "impossible" answer choices, then choose the appropriate one from what's left. (The given line has a negative slope, eliminating choices A and B.)

I like to use the simplest method that will determine the correct answer. Here, that involves reading and understanding the question to obtain some idea of where the desired line must appear on the graph.

Of course, it helps to know that "slope-intercept form" is ...

  y = mx +b . . . . . . m represents the slope; b is the y-intercept

A hiker walks up and down a hill. The hill’s cross section can be modeled by the function y = – 3/4|x – 300| + 400 where x and y
Mkey [24]

Find the vertex by either graphing ( See attached picture) or setting the value in the absolute value bracket to 0:

Vertex is (300,400)

Because it is symmetrical, find the length of one side and double ot for total distance.

Using the distance formula shown on the attached picture.
