Answer:

<em>40 miles per hour. </em>

Step-by-step explanation:

\frac{1}{4} ÷ 22.5 = \frac{1}{4} × \frac{2}{45} = \frac{1}{90} mile per second

\frac{1}{90} × 3600 = <em>40 miles per hour.</em>

A.

You have to convert 22.5 seconds to hours

1st you have to go from seconds -> minutes:
22.5 seconds x 1min / 60secs = 0.375mins

2nd go from minutes to hours:
0.375mins x 1hr / 60minutes = 0.00625hours

Since it is miles per hour, miles would go on top and hours (or seconds in this this case) would go on the bottom.

To find miles per hour:

(1/4) miles / 0.00625 hours = 40 miles per hour.

Therefore, hyena runs 40 miles per hour.

Product in standard form (explain)<br> (3+6i)(4+9i)
ololo11 [35]
First you have to factor (aka, multiply) your binomial (which is what you have written) usually it helps to organize your thinking, and help tell what you need to multiply, to use the binomial chicken(or crab claw, what ever you want to call it) which basically you draw two arches, one arch connecting the 3 and 4, and then the other the 3 and 9i. on the opposite side (depending on wheater you connected then from the top or bottom) you connect (with an arch) the 6i and the four, and then the 6i to the 9i.

so now you multiply each piece you've connected:
3 x 4= 12
3 x 9i= 27i 
6i x 4= 24i
6i x 9i= 54i^2 

after  you've done this you can move on to  putting it into standard form, which just means you put things in descending order, depending on how many exponents the x (or in this case i) has.
your largest exponent is 54i^2, so that's first in out equation, next 27i, and 24i (you can combine these because they are like term) which equals 51i, after that you just add the 12 on the end, so the final equation looks like this:

54i^2+51i+12

What is the equation of a line perpendicular to y= 3/4x +12 that passes through (12, 3)
ycow [4]

Answer:

y=-4/3x-9

 

=

−

4

3

x

−

9

Step-by-step explanation:

First we need to get the slope of the perpendicular line

The slope of a perpendicular line is equal to the negative inverse of the slope of the given line

y

=

m

x

+

b

y

=

3

x

−

⇒

m

m

⇒

m

'

=

−

1

3

4

⇒

m

'

=

−

4

3

Now that we have the slope, we need to find the y-intercept.

To find the y-intercept, we need to plug-in values of  

x

and  

y

that the line passes through

y

Therefore, the equation of the line is

Parallelogram ABCD has the angle measures shown. Can you conclude that it is a rhombus, a rectangle, or a square? Explain.
Hoochie [10]

Answer:

The correct option is parallelogram ABCD is a rhombus, because the diagonal bisects two angles

Step-by-step explanation:

In triangle ABD:

∠B = ∠D

Thus AB=AC by the property of opposite sides of equal angles are equal

In triangle CBD

∠B = ∠D

Thus CB=CD  by the property of opposite sides of equal angles are equal

Thus all four sides of quadrilateral ABCD are equal  

And diagonal BD bisects the angles  

So, it is a rhombus

Therefore the correct option is  parallelogram ABCD is a rhombus, because the diagonal bisects two angles....
