Using the net, we see that the square pyramid breaks down to 4 equivalent triangles and a square. We can use this formula to solve for the surface area:
Sa=A(square)+4*A(triangle)
The formula for the area of a square is
A=l*w
A=7*7
A=49mm²
The formula for the area of a triangle is:
A=1/2b*h
A=1/2*7*12.2
A=42.7mm²
Now that we have the individual areas of the shapes, we can solve for the surface area.
Sa=A(square)+4*A(triangle)
Sa=49mm²+4*42.7mm²
Sa=49mm²+170.8mm²
Sa=219.8mm²
Answer=219.8mm²
ANSWER=A
Answer:
B. Negative
Step-by-step explanation:
So first, we want to locate the variable.
y (x/y) = (y/1) (x/y)
= (xy/y)
= x
The y/y cancels out and now we know we need to find the sign of x. Because x is to the left of 0, it's negative. Anything to the left decreases and anything to the left of 0 is (-).
Answer: d and b i think
Step-by-step explanation:
Answer:
And we want to find this probability: . If we use the bayes rule we have this:
And if we solve we got:
And replacing we got:
Step-by-step explanation:
For this case we define the following notation:
A= A student will take loans to pay for their undergraduate education
B|A= A student will go to graduate school given that the student took loans to pay for their undergraduate education
And we have the following probabilities:
And we want to find this probability: . If we use the bayes rule we have this:
And if we solve we got:
And replacing we got:
