A(2.5, 5.1), B(3, 4.7)

M(\frac{2.5+3}{2}, \frac{5.1+4.7}{2})

M(\frac{5.5}{2}, \frac{9.8}{2})

\boxed{M(2.75, 4.9)}

I need help with this:)

First, find the area of the triangle. The height is 9 and the base is 33. So, multiply the base times height, which is 297. Now, divide 297 by 2. This equals 148.5. Secondly, find the area of the rectangle. Multiply the length times the width. 38•20= 760. Now, add the areas of the two shapes. 148.5+760= 908.5. So, 908.5 is your final answer. :) 
Hope this helps!

Please i don't understand set theory in mathematics
nordsb [41]

Set theory is the mathematical theory of well-determined collections, called sets, of objects that are called members, or elements, of the set. ... The axioms of set theory imply the existence of a set-theoretic universe so rich that all mathematical objects can be construed as sets

For example, if A = {1, 2, 3} and B = {1, 2, 3, 4, 5} then A Í B (Í means is a subset of). If A = {1, 2, 4, 8}, then n(A) = 4. This is because n(A) means the number of members in set A. The universal set is the set of all sets.

Word problem: If 1 yard equals 3 inches, how many inches are in 18 yards?
Mariulka [41]

Answer:

54 inches

Explanation:

From the question, we have that:

1 yard = 3 inches

We are to find the equivalent value of 18 yards in inches. This can be expressed as:

18 yards = x

where x is the unknown value.

Get the value of x by dividing both equations:

\frac{1}{18}=\frac{3}{x}

Cross multiply

\begin{gathered} 1\times x=3\times18 \\  \\ x=54 \end{gathered}

This shows that there are 54 inches in 18 yards

What is mL <br> 38<br> 69<br> 73<br> 90
Ulleksa [173]

The size of Angle L should be the same as Angle C if the triangles are congruent (or at least similar) Since Angle C = 69o, then Angle L also = 69o. You should be very careful in accepting this assumption because looks can deceive. However if the assumption of congruency is not true, there is no way to solve the problem. L = 69o.

When a point lies on the x-axis, what do you know about its y-coordinate? When a point lies on the y-axis, what do you know abou
malfutka [58]
When a point lies on the x-axis, y = 0, the coordinates are ( x , 0 ).
When a point lies on the y-axis, x = 0, the coordinates are ( 0, y ).
