Gideon has a rectangular garden with an area of 19.6 square feet. If the length of the garden is 4.3 feet, what is the length of
Allushta [10]

The length of the diagonal of the garden with 19.6 square feet and 4.3 length is : 6.3 feet

<h3>What is a rectangle?</h3>

A rectangle is a quadrilateral with four sides and four vertices  each of angle 90°.

Analysis:

Area of rectangle: 19.6 square feet

length of one side = 4.3 feet

width of one side = Area/length = 19.6/4.3 = 4.6 feet

the diagonal and width and length of a rectangle for a right angle triangle.

To find the diagonal, we use Pythagoras theorem

(diagonal)^{2} = (length)^{2} + (width)^{2}

(diagonal)^{2} = (4.3)^{2} + (4.6)^{2}

(diagonal)^{2} = 39.7

diagonal = \sqrt{39.7} = 6.3 feet

in conclusion, the diagonal of the rectangular garden is 6.3 feet

The temperature fell from 0Degrees Fahrenheit to 6 and three-fifthsDegrees Fahrenheit below 0Degrees Fahrenheit in 2 and one-fif
stepan [7]

Answer:

B) -3                                 (Sorry if its overwhelming)

Explanation:

First, we have the given information of the weather over a <em>2</em> and <em>1/5</em> <em>span</em>

And we are asked to find the change per hour

We can first start by finding the <em>change</em> for 2 and 1/5 hours:

- Subtract the first amount by the second amount.

= (-6 3/5) - 0

= (-6 3/5) + 0

= -6 3/5

Now that we have the change for <em>2 and 1/5 hours</em> we must find the <em>change</em> per hour:

- Divide the given dividend by the given divisor

= -6 3/5 ÷ 2 1/5

= -3

Hence, the temperature <em>change per hour</em> over a 2 1/5 hour span is -3° per hour

What is the equation of a line parallel to y=(3)/(4)x-5 and passes through (12,-2)?
Vika [28.1K]

A parallel line has the same slope as the original line. So in this case the slope of the line is also 3/4. Now how do we know if it intersects the point? We need to adjust the y intercept.



Currently, we know the equation of the line is y= 3/4 x + b, where b is the thing we are looking for. We also have a point, which supplies the x and y. Plug that in and solve for b

-2 = (3/4)*(12) + b

You'll get b= -11

So the equation of the parallel line intersecting the point given is y= 3/4x -11.

I am assuming that the slope is 3/4 based on the way you formatted the original equation, but it's the same steps if the slope is different.

Which two sets of events are most likely independent?
Bumek [7]

Answer:

A and C

Step-by-step explanation:

Two events, A and B, are independent if the fact that A occurs does not affect the probability of B occurring.

Options B and D give events which are most likely to be dependent, because if a driver texts while driving affects the possibility that the driver can get into the accident and if a woman lives in Alaska affects she can have a heavy winter coat.

Options A and C are two sets of most likely independent events, because the girl's singing does not affect on her wish to become a lawyer and a man's hair doesn't depend on where his father lives.
