Answer:

2

Step-by-step explanation:

.2 of 12 is 2.4 and you can't have 2.4 of a person so it is 2.

I believe the answer is 60. The reason I think it’s 60 is because if 20 percent of the class is 12 students, and you need 5 sets of 20 to make 100 wouldn’t it be 12x5=60? Hope this helps!

TanA+tanB+tanAtanB=1 If A+B=45 degree​
djyliett [7]

Answer:

See below

Step-by-step explanation:

\tan A+\tan B + \tan A.\tan B = 1\\\\ \implies \: \tan A +  \tan B =  1 -  \tan A.\tan B  \\  \\ \implies \:  \frac{\tan A +  \tan B}{ 1 -  \tan A.\tan B } = 1\\  \\ \implies \:  \tan (A +  B) = 1 \\  \\ \implies \:  \tan (A +  B) =\tan 45 \degree \\  \\ \implies \:  A +  B = 45 \degree \\  \\  thus \: proved

Gain finds a skirt that she likes at the store for $45.99. If the tax rate is 5.8%, how much will the shirt cost in all
Aleks04 [339]

Answer:

$48.66

Step-by-step explanation:

The price of a good is the base cost plus tax. We are given the cost of the skirt, so all we need is the amount of tax. To find it, we multiple the cost of the  skirt by the tax rate:

45.99 * 0.058 = 2.67

We now add the tax to the cost of the skirt:

45.99 + 2.67 = 48.66

As you can see, we are adding the price of the skirt to 5.8% of the skirt's price, so we can also solve the problem by simply multiplying the cost by 1.058 as shown below:

45.99 * 1.058 = 48.66

Edison has a sales job and receives $45,448 as his annual pay, plus commission. His company pays him a commission of 15% on his
11111nata11111 [884]

Answer:

Edison will be paid $15,112 for 3 months

Step-by-step explanation:

Edison receives an annual fixed pay = $45,448.

Monthly pay  = 45,448/12 = $3787.33

3-month salary = $3787.33 *3 = $11.362

Commission = 15%

Total sale = $25,000 for the first 3 months.

Commission amount = 25,000*0.15 = $3750

Therefore, total pay that Edison received during first 3 months= salary + commission

= $11,362 + $3750

= $15,112

Thank you.
