"Calculate the square root of 10 (√ 10) to 4 decimal places.<span>Find the perfect square number closer to 10. 32 = 9 and 42 = 16, so take 3.Divide 10 by 3. 10÷3 = 3.33 (you can round off the answer)Average 3.33 and 3. ( 3.33 + 3)÷2 = 3.1667."

First, construct two equations.
Then, equal the two equations to each other like this -
x will be the years.
Type A. Type B
3x + 15 = 4x + 10
- 15. - 15
3x = 4x - 5
-4x. -4x
-x = -5
-x/-1 = -5/-1
x = 5
Check:
3(5) + 15 = 4(5) + 10
15 + 15 = 20 + 10
30 = 30
Therefore, the trees will be the same height in 5 years.
Answer:
Roll a six-sided die five times. The numbers 1 to 4 represent a make,
and numbers 5 and 6 represent a miss. (Correct)
Spin a spinner with three equal sections five times. On the spinner,
one section represents a miss and two sections represent a make. (Incorrect)
Generate a set of five numbers using a number generator with the numbers
0 to 9.The numbers 0 to 7 represent a make, and 8 and 9 represent a miss. (Correct)
Generate a set of five numbers using a number generator with the numbers
0 to 5.The numbers 0 to 3 represent a make, and 4 and 5 represent a miss. (Incorrect)
Spin a spinner with five equal sections five times. On the spinner, four sections represent a make and one section represents a miss. (Correct)
Step-by-step explanation:
You have 2 points with the same x value of 2 and 2 points with the same y value of 4.
You now need 2 points with the same x value of 4 ( you are given 1) and 2 y values of 1 ( you are given 1.
The missing point would need to be (4,1)
The width would be x2-x1 = 4-2 = 2 units
The length would be y2-y1 = 4-1 = 3 units
Area = 3x 2 = 6 square units
