If an item costs $45 and we must pay 6% sales tax, how much will we pay for the item?
Gennadij [26K]

$47.70

$45 with 6% sales tax

6%=.06

To find total amount multiply by 1.06 or multiply by .06 and that is tax amount and then add it to the $45

$45*.06=2.70 amount of tax

$45*1.06=47.70 total amount paid

Any questions feel free to ask. Have a great day!

A ball is tossed between three friends. The first toss is 8.6 feet, the second is 5.8 feet, and the third toss is 7.5 feet, whic
algol13

Answer:

The angles are 79.45, 59.02 and 41.53 degrees to the nearest hundredth.

Step-by-step explanation:

We have a triangle with sides of length 8.6, 5.8 and 7.5 feet.

Using the Cosine Rule to find the measure of the angle opposite the side of length 8.6 feet:

cos X =  (8.6^2 - 5.8^2 - 7.5^2) / ( -2*5.8*7.5)

=  0.18310

X =  79.45 degrees.

We can now find another angle using the sine rule:

8.6 / sin 79.45 =  7.5/ sin Y

sin Y = (7.5 * sin 79.45) / 8.6

Y = 59.02 degrees

So the third angle = 180 - 79.45 - 59.02

= 41.53 degrees.

Y’all i’m stuck help me

<h3>Answer: Choice E</h3>

======================================================

Explanation:

Think of 25 as 25/1 and 5 as 5/1

Choice E is really saying \frac{25}{1} \div \frac{5}{1} which becomes \frac{25}{1} \times \frac{1}{5}. Note the second fraction flips and we change to a multiplication sign.

------------

Or you could think of it like this:

25 \times \frac{1}{5} = \frac{25}{1} \times \frac{1}{5} = \frac{25*1}{1*5} = \frac{25}{5} = 25 \div 5

to help see why the answer is E.
