I would make the equation have both of your variables on the same side:
0.1x+y=1
Then I would use the cover-up method and say that
x-intercept= 10
y-intercept= 1
*Cover-Up Method: If you were finding the X-intercept, you would just ignore the y variable and divide your whole number by x.
In this case the whole number is 1. 1/0.1=10
Vice Versa with finding the Y-intercept
Answer:
a) 910
b) 828100
c) 144320
Step-by-step explanation:
a. ∑y
This is the sum of all values of y. So
b. (∑y)^2
This is the square of the sum, so the square of 910, that we found in the previous item.
910² = 828100
c. ∑y^2
This is the sum of the squares of each amount spent. So
Step-by-step explanation:
the volume of a cube is
side³.
since the volume is 27 m³, the individual side lengths are then the cubic root of 27 = 3 m.
the surface area is 6 squares of 3×3 = 9m², so in total
9 × 6 = 54 m²
we are given with 70 grams and is said that 48 grams is taken away. This is equal to 22 grams. To find the mass percentage, we divide the remaining mass and divide by the total mass. The remaining 22 grams is equal to 22/70 * 100 percent equal to 31.43 percent.
240 plz like my awnser it would mean alot
