Answer:

She thought the multiplication symbol was the addition symbol

actual answer: 1.39 x 10^12

Step-by-step explanation:

If it was addition, then she’d be correct;

6.75x10^6 + 0.2x10^6

= (6.75 + 0.2)x10^6

= 6.95x10^6

But really, it was a multiplication, meaning the answer really is;

(6.95x10^6)x(0.2x10^6)

= 1.39 x 10^12

Answer:

While slavery was the major issue separating the North and South, it was not slavery itself that sparked the conflict. The South wanted to secede from the Union, and the North refused. While President Abraham Lincoln personally opposed slavery, he recognized that it was legal under the U.S. Constitution at the time. He also recognized that few in the North were ready to go to war to free the slaves. For Lincoln and the northern majority, preservation of the Union was the foremost goal.

Ilia_Sergeevich [38]

Answer:

AC = \sqrt{89} units²

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse AC is equal to the sum of the squares on the other 2 sides, that is

AC² = AB² + BC² = 5² + 8² = 25 + 64 = 89 ( take square root of both sides )

AC = \sqrt{89} ≈ 9.43 ( to 2 dec. places )

Two friends go out to eat and order the same meal. They pay a 6% sales tax and a 20% tip on their meals. The total bill, includi
vova2212 [387]

Sales tax and tip will increase the price of an item.

The cost of each meal is: $10.89

Let the cost of both meals be x.

A 20% tip means that, the current price is:

Price = x \times (1 + 20\%)

A 6% sales tax on the meal means that, the current price is:

Price = x \times (1 + 20\%) \times (1 + 6\%)

So, we have:

Price = x \times (1 + 0.20) \times (1 + 0.06)

Price = x \times (1.20) \times (1.06)

Price = x \times 1.272

The amount paid is $27.72

So, the equation becomes

27.72= x \times 1.272

Make x the subject

x = \frac{27.72}{1.272}

x = 21.78

So, the cost of each meal is:

Each= \frac{21.78}{2}

Each= 10.89

Hence, the cost of each meal is: $10.89
