The distance between any two points is:
d^2=(x2-x1)^2+(y2-y1)^2 so in this case:
d^2=(7-4)^2+(-3-6)^2
d^2=3^2+9^2
d^2=90
d=√90
d=3√10 units
d≈9.49 units (to nearest hundredth of a unit)
Add all 15 students' amounts: 14(68 inches), then add 65. Take the sum and divide it by 15 students, to get the mean. The answer is 67.8
Answer:
81y4 - 16x2, the difference of squares
18+12*4=18+48=66 ft
1st floor is 18ft
next 4 are 12ft
Answer:
12 feet.
Step-by-step explanation:
1 inch = 4 feet.
Multiply 3 by 4.
3×4=12
I multiplied 3 by 4 because 1-inch equals 4 feet, which means if we multiply both terms by 3, you will get 3 inch = 12 feet.
Hope this helps!
