Answer:

$-\frac{40}{91}$

Step-by-step explanation:

The equation to find the slop of a line using two points that consist of (x,y) is $\frac{y_{2} -y_{1}}{x_{2}-x_{1}}$ . All you do is plug the numbers into the equation you end up with $-\frac{40}{91}$

What is the area of this ^2

Ad libitum [116K]

<h2>Question:- Area of the given diagram</h2>

<h2>Answer :- </h2>

Divide the diagram as shown in attachment.

Now first calculate the area of the rectangle having side 1 and 12

So area = length ×breadth

Area = 1× 12 = 12 unit²

Now find the Area of the remaining triangle with sides 12,13,5 units

$Area = \frac{1}{2} \times base \times height \:$

Now put the value as -> base= 5 and height= 12

$Area = \frac{1}{2} \times base \times height \: \\ Area = \frac{1}{2} \times 5 \times 12 \\ Area = \frac{1}{ \cancel2} \times 5 \times \cancel{12}^{ \: \: 6} \\ Area = 5 \times 6 \\ Area = 30 \: units^{2}$

Now add both areas for your answer

$Area{ \tiny{1}} = 12 {units}^{2} \\ Area{ \tiny2} = 30 {units}^{2} \\ Area{ \tiny{total}} = Area{ \tiny{1}} + Area{ \tiny{2}} \\ Area{ \tiny{total}} = 12 + 30 = 42 {units}^{2}$

Hugh bought some magizines that cost 3.95 each and some books that cost 8.95 each. He spent a total of 47.65.If Hugh bought 3 ma

HACTEHA [7]

Answer:

4 books

Step-by-step explanation:

We are told that: Hugh bought some magazines that cost 3.95 each

Hugh bought 3 magazines.

Hence, total cost of magazines = 3 magazines × 3.95

= 11.85.

Total cost of magazines = 11.85

From the question, we know that, the total amount Hugh spent = 47.65

Hence, The total cost for books =

Total amount spent - Total cost of magazines

= 47.65 - 11.85

= 35.80

Therefore, the total cost of books = 35.80

We are told in the question that the cost of books is 8.95 each or 8.95 per book.

Hence, the number of books that Hugh bought is calculated as :

35.80/8.95

= 4 books

Therefore, Hugh bought 4 books

A small plane flew 240 miles in 2 hours.At that rate how long will it take to travel 600 miles?please so me the work

Furkat [3]

So, in 240 miles can be made by 2 hours.
Do this equation:

240 × 2 = 480 / 4 hours.

You cannot do 3 because it won't fit another 240 miles.

Next, subtract the 480 miles from 600 miles.

600 - 480 = 120

Also, if you would've divided by 2 hours.

240 ÷ 2 = 120 / 1 hour

Add the hours.

4 + 1 = 5 hours

It takes 5 hours to travel 600 miles by the small plane.
