Answer:

Step-by-step explanation:

Triangle is an example of a polygon with three sides. The types of triangle we have are the equilateral, isosceles, scalene and right angled triangle.

An equilateral triangle is a triangle that has all its 3 sides and angles equal.

An isosceles triangle is a triangle that has two of its sides and angles equal.

A scalene triangle is a triangle that has none of its sides and angles to be equal.

According to the question, we are given a triangle of lengths 9, 10 and 130. It is seen that all the length of each sides of the triangle is different, this makes it a scalene triangle.

What is the value of x in the equation 1/3x − 2/3 =− 18?

Klio2033 [76]

Answer:

x = -52

Step-by-step explanation:

$\frac{1}{3}x-\frac{2}{3}=-18$

Let us solve for x.

$\frac{1}{3}x=-18+\frac{2}{3}$

$\frac{1}{3}x=-\frac{18*3}{1*3} +\frac{2}{3}$

$\frac{1}{3}x=-\frac{54}{3} +\frac{2}{3}$

$\frac{1}{3}x=\frac{-54+2}{3}$

$\frac{1}{3}x=\frac{-52}{3}$

Use cross multiplication to find the value of x.

$\frac{1x}{3}=\frac{-52}{3}$

$3*1x=3*-52$

$3x=-156$

Divide both sides by 3.

x = - 52

Alex paid $4.40 for 2.5 pounds of walnuts . What is the cost of one pound of walnut

igomit [66]

Answer:

Therefore, the price would be 1.76 per pound of the walnut.

Step-by-step explanation:

To calculate the price per pound of the walnut, we just have to divide that price that Ava paid for the given amount of walnuts. We calculate as follows:

Price per pound = 4.40 / 2.50 pounds of walnuts

Price per found = 1.76 / pound of walnut

- Varun drove to work this morning. It took

babymother [125]

Answer:

See attached graph

Step-by-step explanation:

The graph of distance from home as a function of time starts at the origin of coordinates (0,0) since at time zero minutes Varun is at home.

Then we represent his driving at constant speed (although it has not been specified in the problem) as a line with positive slope equal to his speed, that goes on for the first five minutes. After that, he reaches the traffic light that keeps him at the same distance from home for three minutes (notice the line representing the distance covered is flat from minute 5 to minute 8, while he is not moving).

Then he starts moving again (we assume at the same speed as before - so the line representing his position is again a line with positive slope and with the SAME inclination as that which represents the first 5 minutes of his trip.

The line ends at minute 15 which is the time it took him to get to work.
