Y=mx+b is what I learned and point slope is y-y1=m*x-x1
Answer:
D
Step-by-step explanation:
If x is not equal to zero, then 1/x can be equal to x.
So which is k * 1/x if x =1?
D, because x is the same as 1x, which is equivalent to 1/1 (x).
I may be wrong though please look at other answers and if you have questions then comment
Ratio of men:women in the simplest form is 7:8
Step-by-step explanation:
- Step 1: Given total adults = 150. Number of women = 80. Find the number of men.
Number of men = 150 - 80 = 70
- Step 2: Find the ratio between men and women.
Men:Women = 70:80 = 7:8
Answer:
S.A = 147.35 cm²
Step-by-step explanation:
Surface area of the triangular pyramid = base area + ½(perimeter of base*slant height)
Base area = ½*bh
b = 7 cm
h = 6.1 cm
Base area = ½*7*6.1 = 21.35 cm²
Perimeter of triangular base = 7 + 7 + 7 = 21 cm
slant height = 12 cm
Plug in the values into the equation
S.A = 21.35 + ½(21*12)
S.A = 21.35 + 126
S.A = 147.35 cm²
Answer:
(B)The surface area is equal to the area of its two-dimensional net.
Step-by-step explanation:
The surface area of a 3D object is the sum of the areas of the various sides that make up this figure. Essentially, if you unroll the object into its 2D net, then the area that this net covers will be the surface area.
Think about a cube, for example. It has 6 square sides, so its surface area is the sum of the areas of those squares. If we take the net of the cube, it's also 6 squares, and if we sum those together, we'll get the same answer.
Thus, the answer is B.
