Answer:

∠AB=9

Step-by-step explanation:

the pyagrothyes therom= $a^{2}$ + $b^{2}$ = $c^{2}$

to find ∠AB we need to find the height of the triangle.

replace the variables:

$a^{2}$ + $6^{2}$ = $9^{2}$

= $9^{2}$ - $6^{2}$ = $a^{2}$

simplify:

81-36= $\sqrt{45}$

now we solve for ∠AB

replace the variables:

$6^{2}$ + $\sqrt{45}$ = $c^{2}$

simplify:

36+45= $\sqrt{81}$

$\sqrt{81}$ =9

I hope this helps you!!

have a nice day!!

JulsSmile [24]

We know that there is a total of 900 cells, and 37 of the samples 60 are red. 900/60 is our unit rate of 15. 37 times 15 is 555. We will see 555 red blood cells in all of the cells.

555 is our answer.

Suppose that there are two types of tickets to a show: advance and same-day. Advance tickets cost $30 and same-day tickets cost

Tju [1.3M]

The advance tickets were 35 in number and the same day ticket will be 30 in number.

<h3>What will be the number of tickets?</h3>

To find out the number of the tickets sold we will give some notations so the notations are as follows:-

A= Cost of advance tickets=$30

S= cost of same-day ticket-=15

$N_A=$ Number of the advance tickets

$N_S=$ Number of same-day tickets.

The equations made by the given data will be:-

$30N_A+15N_S=1500\\\\\\N_A+N_S=65$

By solving the above equations:-

$N_S=30\ \ \ \ \ \ N_A=35$

Hence the advance tickets were 35 in number and the same day ticket will be 30 in number.

Select all the common denominators for

Vitek1552 [10]

Answer:

B, E

Step-by-step explanation:

There are a few ways to check for common denominator.

Here is one method

Take the 4 and 10 and see if both numbers will go into the numbers evenly. If they do, it is a common denominator

Will 4 and 10 divide evenly into 10 ?

4 will not go into 10 evenly

10 is not a common denominator.

Will 4 and 10 divide evenly into 20?

4 will go into 20 evenly. 20 /4 = 5

10 will go into 20 evenly 20 / 10 = 2

So 20 is a common denominator

Will 4 and 10 divide evenly into 24?

4 will go into 24 evenly 24 / 4 = 6

10 will not go into 24 evenly

24 is not a common denominator

Will 4 and 10 divide evenly into 32?

4 will go into 32 evenly 32 / 4 = 8

10 will not go into 32 evenly

32 is not a common denominator

Will 4 and 10 divide evenly into 40?

4 will go into 40 evenly 40/4 = 10

10 will go into 40 evenly 40 / 10 = 4

40 is a common denominator
