Answer:

My total savings was = $58.33

Step-by-step explanation:

Given:

12% of my savings was = $7.00

To find my total savings.

Solution:

Let the total savings in dollars be = x

12% of the total savings will be  = 12\%\ of\ x

12% of my savings was = $7.00

So, we have:

12\%\ of\ x=7

0.12x=7

Solving for x to get my total savings.

Dividing both sides by 0.12

\frac{0.12x}{0.12}=\frac{7}{0.12}

∴ x=58.33

Thus, my total savings was = $58.33

In the right triangle shown, A= 30° and AB = 8.
zloy xaker [14]

Answer:

BC=4\ units

Step-by-step explanation:

The picture of the question in the attached figure

we know that

sin(30^o)=\frac{BC}{AB} ----> by SOH (opposite side divided by the hypotenuse)

we have

AB=8\ units\\\\sin(30^o)=\frac{1}{2}

solve for BC

BC=sin(30^o)(AB)

substitute the values

BC=(\frac{1}{2})(8)

BC=4\ units

Please help. Thanks <3

The answer would be A.
Deena is correct because that is not a rational number
Irrational numbers are numbers that are crazy and don’t have an end to them. Example would be pi because it goes on forever and ever. But it you have something that is straight to the point like 2.3 or -4/7 these are RATIONAL because they have an end and are “contained”, this goes for numbers that are repeating too.. if you have like 2.3repeating, then this is also rational because you know what the number is, and it is consistent.
I hope this helps explain rational and irrational a little better :)
