Answer:
Step-by-step explanation:
It is simply the sumation of a triangle and a rectangle minus a half circle.
area triangle + area rectangle - area half circle = Total area
1/2( bh ) + bh - (π (d/2)²) / 2 = Total area
0.5(7)(6) + (10)(7) - (π (7/2)² ) / 2 = Total area cm²
21 + 70 - 19.24 = 71.76 cm²
Answer:
x greater than and equal to -7
Step-by-step explanation:
Parabola touches at -7 and is going straight towards all positive integers
Therefore the domain is all numbers greater than or equal to -7
Answer:
3/4=75%
Step-by-step explanation:
There are 4 sections of the spinner. Any of the 4 could occur. 0 is one part of the 4 making it one fourth. Everything that's not 0 is 3 parts of the spinner meaning it has a probability of 3/4=75%
Sqrt 80n^2 = sqrt 40x2xnxn = sqrt 20x2x2xnxn = sqrt 10x2x2x2xnxn = sqrt 5x2x2x2x2xnxn
Pull out numbers and letters in groups of 2
2x sqrt 5x2x2xnxn
2x2x sqrt 5xnxn
2x2xnx sqrt 5
Multiply the numbers and letters on the outside of the radical
4n x sqrt 5 is the final answer.
First you add up the red and black so see how many she has total.
45 + 60= 105
then if you need to find the probability of the red candies you put
45/ 105
then you can simplify it so it would be 8/21
45+60=105
45/105= 8/21
