Answer:
The area is 22.5 units
The perimeter is 24.3 units
Step-by-step explanation:
The formula for the area of a triangle is A=bh(1/2)
So, base*height (5*9) is 45. Divide that by 2, and you get 22.5.
To find the perimeter, it looks like the triangle is a right triangle. To solve for that, use the Pythagorean theorem formula: a2 + b2 = c2.
5^2+9^2=c^2
25+81=106=c^2
Find the square root of 106
10.2956301
If your teacher usually asks to round, round.
I'll just round to the tenths place. 10.3
Add all the sides: 5+9+10.3
You get 24.3
A is the quickest way to do the problem.
Answer: y = (1/7) x - 2
Step-by-step explanation:
The slope-intercept form of an equation is y = mx + b, where m is the slope and b is the y-intercept.
The slope of an equation is the change in y over the change in x.
We can see from the image that every time the line increases by 1 in the rise (y), it increases by 7 in the run (x).
Therefore, the slope is 1/7.
The y-intercept of a line is the point at which it intercepts the y-axis.
From the image, we can see that it intersects at the point (0,-2)
Therefore, the slope-intercept form is y = (1/7) x - 2
Answer:
248
Step-by-step explanation:
Divide 62 by 2 to get 31. Each distance on the map should be multiplied by this number. So if it's 8 on the map, its 8 x 31 in real life. 8 x 31 = 248
