B.) infinite solutions.

The reason I say this is because there is an arrow pointing down past the number line meaning that the number line never ends.

Hope this helps.

Someone helpp !! I don’t understand this at all

Naddika [18.5K]

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!!

Let second number be x.

First number= 6x

Third number= 3x

According to question,

6x+x+3x=121

or, 10x=121

or,x=121/10=12.1

PLEASE HELP 20 POINTS IF YOU HELP AND WILL BE MRAKED BRAINLEST!!!!!!!!!!!!!!!!The two-way table below shows the number of studen

Yuliya22 [10]

Your answer is the last option, 6.

We can work this out by looking for the total of people that like tennis in the table, and subtracting it from the total amount of people that like baseball.

This gives us a total of 46 people that like baseball, subtract 40 people that like tennis, and 46 - 40 = 6.

I hope this helps!
