Elan Coil [88]3 years ago

The 3rd questions answer is: In order to solve this, you need to add 20% of the $7.50 TO the $7.50.
First, multiply 0.20 x $7.50 = $1.50
Then, add the $1.50 to the original $7.50 because the price is increasing by 20%, so the new price of the ticket is $9.00. (I got this answer because someone else asked this question on BRAINLY and this was an answer, it’s correct btw)

Answer:

  1. 3x + 5
  2. x² + 3x + 2
  3. $9

Step-by-step explanation:

3. The price was $7.50

Increasing by 20%,

20% of $7.50 is 7.50 × 20/100

= 750/100 × 20/100

= 75/10 × 2/10

= 15/2 × 1/5

= 3/2 × 1

= 3/2

Increasing by 20% = $7.50 + 3/2

750/100 + 5/2

75/10 + 5/2

75/10 + 15/10 = (75+15)/10 = 90/10 = $9

HOPE THIS HELPS YOU

Multiply. Your answer should be a monomial in standard form. {(-t^7)(-t^5)}
allochka39001 [22]

Answer:

t^12

Step-by-step explanation:

Because both multiplicands are negative, their product will be positive.  Both multiplicands are to the same base:  t.

Therefore, the product is t^(7 + 5), or t^12.

A man comes into a store and steals $100 from the register without the owner knowledge. Comes back and buys $70 worth of stuff a
Naya [18.7K]

There are many real world complications to this problem. However, if we're just looking at the surface, he lost $100 worth of currency and goods.

Think about it this way: The owner had $100 in cash and $70 in goods. The man takes the 100 and leaves. Owner now has just the goods. Man comes back replaces the 100. He now grabs the goods ($70) and the change ($30) 70 + 30 = 100.

The owner lost $100 in both goods and currency.

REAL WORLD APPLICATION:

The owner would not have lost this much money. Most stores pay a wholesale price rather than paying per unit at retail value. The $70 worth of goods would not have cost the store $70 to purchase.

Example: Your local GameStop may have many copies of Madden for sale but, surely they did not pay $60 per Madden disc, the retail value for a new game. They paid one set price and were given a number of units to sell at their store for that price. When the math is done on it, you would see that they paid less than that per unit. Otherwise, they would have no incentive to be in business... in fact, there would be no business at all, they would just be a middle man for no reason; they'd make no money on the exchange.

So the real world answer would be no one would be able to know how much money the owner lost other than the owner and his accountant/financial advisor.

Given that log_{a}(3) = 0.477 and
kipiarov [429]

Given:

\log_{a}(3) = 0.477,\log_{a}(5) = 0.699

To find:

The value of \log_{a}(0.6).

Solution:

We need to find the value of:

\log_{a}(0.6)

It can be written as

\log_{a}(0.6)=\log_a\left(\dfrac{6}{10}\right)

\log_{a}(0.6)=\log_a\left(\dfrac{3}{5}\right)

By using the property of logarithm, we get

\log_{a}(0.6)=\log_a(3)-\log_a(5)        [\because \log \dfrac{a}{b}=\log a-\log b]

\log_{a}(0.6)=\log_a(3)-\log_a(5)

On substituting the given values, we get

\log_{a}(0.6)=0.477-0.699

\log_{a}(0.6)=-0.222

Therefore, the values of \log_a(0.6) is -0.222.
