Answer:
2+8×6÷3-6 = 2+48÷3-6 = 2+16-6 = 12
Answer:
14
Step-by-step explanation:
if it's 2 teachers for every 45 students, I assume you would divide 315 by 45 which would give you 7 groups of 45. now for every group you would require 2 teachers. and 2 times 7 is 14.
Answer:
<h3>A (-4,3)</h3>
Step-by-step explanation:
THe formula for calculating midpoint is expressed as;
M(X, Y) = {(x1+x2/2), y1+y2/2}
Given
Midpoint = (2, 5)
K = (8, 7)
Required
Coordinate of M
X = x1+x2/2
2 = 8+x2/2
4 = 8+x2
x2 = 4-8
x2 = -4
Similarly;
Y = y1+y2/2
5 = 7+y2/2
10 = 7+y2
y2 = 10-7
y2 = 3
Hence the coordidates of M is at (-4,3)
I will only answer 1, 4, and 5 for you.
#1.
2pm = 10 feet, 6pm = 2 feet
You would subtract so 6 - 2 = 4 hours
10 - 2 = 8 hours
The water went down 8 feet in 4 hours
Then you'd find how many feet it went down in an hour, which you'd divide
8/4 = 2 feet
The constant rate of the water would be 2 feet/hour
#4.
Jazz = 43 inches tall, 18 months later Jazz = 52 inches tall
Again, you'd subtract just like we did in #1.
52 - 43 = 9 inches
Then you'd divide 9 inches into the 18 months
9/18 = 0.5
So Jaz grew 0.5 inches.
#5
For this question, all you have to do is look at the graph. You see those points? Look at the numbers on the side, you will see that they increase by 10 each time. So there's your answer! Toby biked 10 miles per week.
1,3,9,27,81 are the number factor of 81.
