Flura [38]

Answer:

Angle, $\theta=70.4^{\circ}$

Step-by-step explanation:

We have, an A-frame house is 45 feet high and 32 feet wide. It is required to find the measure of the angle that the roof makes with the floor.

The attached figure shows the A frame. Let $\theta$ is the angle that the roof makes with the floor. So,

$\tan\theta=\dfrac{45}{16}\\\\\tan\theta=2.81\\\\\theta=\tan^{-1}(2.81)\\\\\theta=70.4^{\circ}$

So, the angle of 70.4 degrees is the angle that the roof makes with the floor.

Helping my daughter with ratio table homework. I do not understand the concept of the tables. Here is one of her questions that

Lisa [10]

First you divide $4000 by 160 to see how much each book costs. Then you multiply 2 times the cost for each book and subtract that from $4000.

$4000/160= $25
$25=1 book
So if the store gives away 2 books that's $50 dollars. $4000-$50 equals 3,950

The plate is rotated 90° about the origin in the counterclockwise direction. In the rotated trapezoid, what are the coordinates

Crazy boy [7]

You haven't provided the coordinates of the original trapezium, therefore, I can only help with the concept.

From the givens, we can know that the rotation was 90° counter-clockwise about the origin.

<u>The rule for this rotation is:</u>

(x , y) ..............> (-y , x)

This means that to get the points of the rotated image, negate the y-value then exchange it with the x-value

<u>Examples:</u>

(1 , 3) rotated 90° counter-clockwise about the origin will give (-3 , 1)

(-2 , 4) rotated 90° counter-clockwise about the origin will give (-4 , -2)

(1 , -2) rotated 90° counter-clockwise about the origin will give (2 , 1)

(-3 , -5) rotated 90° counter-clockwise about the origin will give (5 , -3)

Hope this helps :)

Standard automobile license plates in a country display 2 digits, followed by 2 letters, followed by 3 digits. How many differen

fomenos

Answer:

There are 1,892,800,000 different standard plates that are possible in this system

Step-by-step explanation:

The plates follow the following format:

D - D - L - L - L - D - D - D

For each digit there are 10 possible outcomes, and for each letter there are 26 possible outcomes.

So, there are

10*10*26*26*28*10*10*10 = 1,892,800,000

different standard plates that are possible in this system
