Answer:
So use pythogoras theorem
a^2=c^2-b^2
a^2 = 20^2-12^2
a^2= 256
a= square root of 256
length is 16 ft
area = l x w
= 16 x 12
Area is 192 square feet
Step-by-step explanation:
8 units to the left and 5 units up.
Just pick any point on the blue triangle and count how many you move to get to that same point on the red triangle.
The last one is the answer.
If the number is no less than 6, that means that it is not any smaller than 6.
That narrows the answer down to x > 6 and x >= 6. The difference between these two choices is that x>6 means that x cannot equal 6, while the last choice is greater than OR equal to 6.
Since we are looking for when the minimum value for x is 6, x >= 6 is the answer.
Answer:
17.99
Step-by-step explanation:
18-0.01=17.99
For this case, the first thing we must do is define variables:
x: students of group 1
y: students of group 2
We now write the system of equations that models the problem:
Solving the system by substitution we have:
Then, the value of y is given by:
Answer:
8 students of group 1
20 students of group 2
