Answer:
D. 27 square feet per hour
Step-by-step explanation:
Step 1:
Find the unit rate. Since 18 tiles are per 2/3 of an hour, we can divide 18 by 2 to get 9 tiles layed per third hour.
Step 2:
Multiply the 9 per third of an hour by 3 to find how many are per hour,
square feet per hour
This is called finding the unit rate of a scenario.
The second one! hope this helped :)
Answer:
0.5+8
Step-by-step explanation:
The slope intercept form is mx+b
Mx is the slope
b is the y intercept
The slope formula is y2-y1/x2-x1
2 points to find the slope:
(2,9) (4,10)
10-9=1
4-2=2
1/2=0.5
The y-intercept is the number that goes through the number line when x equals 0. The y intercept is 8.
Answer:
8.18 cubic inches
Step-by-step explanation:
An orange is a sphere so you will use the formula for the volume of a sphere.
V= 4
/3 * π * r^3 r^3= 1.25* 1.25 * 1.25= 1.953
V= 4/3* 3.14 * 1.953 = 8.176=8.18
