Answer: OPTION D
Step-by-step explanation:
The formula for calculate the surface area of a rectangular prism is:
Where w is the width, h is the height and l is the length.
You can see in the figure attached that:
l=3.4ft
w=3ft
h=4.1ft
Therefore, when you substitute these values into the formula you obtain that the surface area is:
Answer:
mean = 11.66666
median = 11
Step-by-step explanation:
To find the mean, add up all the numbers, then divide by how many numbers
mean = (15+9+13+18+9+6) / 6 = 70/6 = 11 .6666666
To find the median, put the numbers from smallest to largest. then take the middle number. Since there is an even number, take the two middle numbers and average them
6,9,9,13,15,18
The two middle numbers are 9 and 13
(9+13)/2 = 22/2 = 11
Answer:
Step-by-step explanation:
We want to write the equation of a line that passes through (5, 6) and (-1, 4).
First, let's find our slope. We can use the slope formula:
Let's let (5, 6) be (x₁, y₁) and let's let (-1, 4) be (x₂, y₂). So, our slope is:
Subtract:
Reduce:
So, our slope is 1/3.
Now, we can use the point-slope form, which is:
For consistency, let's let (5, 6) be (x₁, y₁). We will also substitute 1/3 for m. So:
Distribute:
Add 6 to both sides:
Add:
And we're done!
Answer:
Answer:
B only
Step-by-step explanation:
In A and in C, only the angles of
one triangle are congruent to the
corresponding angles of the other
triangle. That proves similar triangles but
not necessarily congruent triangles.
Definition of congruent triangles:
Two triangle are congruent if all angles
of one triangle are congruent to all
corresponding angles of the other
triangle and all sides of one triangle are
congruent to all corresponding sides of
the other triangle.
That happens only with the triangles in B.
Answer: B only
