Analyze the diagram to complete the statements. The m∠MXN is the m∠YZX. The m∠LZX is the m∠ZYX + m∠YXZ. The m∠MYL is 180° − m∠ZY

Xelga [282]

By using the picture that was provided below, you can see that

m<MXN is greater than m<YZX.

Angles m<LZX is equal to m<ZYX + m<YZX and

m<MYL is equal to 180 degrees minus M<ZYX.

I hope this helps! Have a good day

A bookseller bought 80 books at rs 30 each 20 books were stolen and he sold the remaining books at 5% loss find the selling pric

Blizzard [7]

Answer:

rs 38.

Step-by-step explanation:

Total cost of the 80 books = 80*30 = rs 2400.

He had 60 books to sell and made a 5% loss.

Thus his income from these books was 2400 - 0.05*2400 = rs 2280.

So the selling price of each book was 2280 / 60 = rs 38.

What is another way to group the factors (3x2)x5

tia_tia [17]

<u>Answer</u>

3×(2×5)

<u>Explanation</u>

Multiplication of numbers is associative. For example,

(a×b)×c = a×(b×c)

This is also called grouping. We multiply more than 2 numbers by grouping.

For the equation given above, (3x2)x5, it can also be grouped as 3×(2×5).

"You are going to make a trash bin with a square base , vertical sides and no top. If you have 108 ft2 of material available, de

kotykmax [81]

<h2>Dimension of trash bin is 6 ft x 6 ft x 3ft .</h2>

Step-by-step explanation:

Let h be the height of box and a be the side of base square.

We have 108 ft² material.

Surface area of trash bin = 108 ft²

Surface area of trash bin = a² + 4 ah

a² + 4 ah = 108

4ah = 108 - a²

$h=\frac{108-a^2}{4a}$

Volume of trash bin, V = a²h

$V=a^2\times \frac{108-a^2}{4a}=27a-0.25a^3$

At maximum volume differentiation of volume will be zero

$dV=27da-0.25\times 3a^2da\\\\0=27da-0.75a^2da\\\\a^2=36\\\\a=6ft$

Surface area of trash bin = a² + 4 ah = 108

36 + 4 x 6 x h = 108

h = 3 ft

Dimension of trash bin is 6 ft x 6 ft x 3ft .
