Answer: Its very simple to solve slopes
Step-by-step explanation:
All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.
Answer:
5 11/12
Step-by-step explanation:
First convert the mixed number into an improper fraction: 31/6
Find a common denominator:
18/24 and 124/24
124/24+ 18/24 is 142/24 and that is the same as 5 11/12
Hopefully this helps and you can have a lovely day!
Let's find the area of each shape that makes up the prism. Let's first start with the triangles.
There are two identical triangles on both ends of the prisms. They have a height of 12 and a base 18. Let's find the area of both of the triangles.
12×18=216
216 is the area of both triangles. Each triangle has an area of 108 though.
Let's find the area of the two rectangles.
There are two identical rectangles that are 30 m by 15 m. Let's find the area of both.
30×15=450×2=900
So, the area of both rectangles together is 900.
Let's find the area of the rectangle that acts as the base in the picture.
There's only one and it's 30 m by 18 m.
30×18=540
Let's add everything together.
540+900+216
1440+216
1656
So, the surface area is 1656 m².
Answer:
-3
Step-by-step explanation:
f(x)= x²+3x-1
f(-1)= (-1)²+3(-1)-1
= 1-3-1
= -2-1
= -3
