Answer:

e) none of these

Step-by-step explanation:

Side of square = \sqrt{10^{2}+20^{2} }  = \sqrt{100 + 400}  = \sqrt{500} =10\sqrt{5} units\\Area of square =side * side \\= 10\sqrt{5} * 10\sqrt{5} = 10 * 10 * 5 = 500 sq.units\\

What is −300 ÷ (−13) = and how would i write out this problem to solve?
never [62]

Answer:

  23 1/13

Step-by-step explanation:

You have done a pretty good job of writing the problem, negative 300 divided by negative thirteen. It can be translated directly to your favorite calculator (see attachment) for a solution.

If you want to perform the division by hand, the particular method of writing the problem depends on the method of division you want to use. (Several styles are taught these days). Numerous web sites and videos explain <em>long division</em> in all its detail. The second attachment shows an example where a decimal fraction result is obtained. The decimal fraction is an infinite repeating decimal with a 6-digit repeat.

For starters, you would generally convert both numbers to positive numbers, since the result of 300/13 is the same as the result of -300/-13 and positive numbers are easier to deal with.

___

<em>Comment on symbols</em>

(The symbol ÷ generally means the same thing as the symbol /. Both mean "divided by". In some cases, the symbol ÷ is given the meaning "everything to the left of it divided by everything to the right of it." This is often the case when it is used as part of a compound fraction: 3/5÷4/3, for example. The preferred representation of such a division is (3/5)/(4/3), with parentheses clearly identifying numerators and denominators.)

Question Solve for x 3x = x + 8​
Viktor [21]

Answer:

x=4

Step-by-step explanation:

here's our equation: 3x=x+8

Our goal: to isolate x onto one side with nothing else on that side.

x is on both sides; we can subtract x from both sides to make the variables and numbers be on different sides

2x=8

Now we can divide by 2

x=4

Hope this helps! :)

Find the value of x for which the graph of y = 3x^2 - 8x + 7 achieves its minimum y-value.​
gulaghasi [49]

Answer:

<h3>The y value achieves its minimum at x = 4/3</h3>

Step-by-step explanation:

Given the graph of y to be 3x² - 8x + 7, to get the value of x for which the graph function achieves its minimum y value, we need to find its turning point first.

At the turning point, dy/dx = 0

Given y = 3x² - 8x + 7

\frac{dy}{dx} = 6x-8\\ at\ turning\ point\ 6x-8 = 0

6x = 8\\x = \frac{8}{6}\\ x =\frac{4}{3}

The y value achieves its minimum at x = 4/3

Solve for the final amount you need to pay. Chinese foos $120 for delivery. You want to pay 15% tip. How much money total money
gogolik [260]

Answer:

<em>$150</em>

Step-by-step explanation:

Given

Delivery amount = $120

Percent tip on the delivery amount = 15%

Tip amount = 15% * 120

Tip amount = 0.15 * 120 = $30

Total money paid = Delivery amount + Tip

Total money paid  = $120 + $30

Total money paid = $150

<em>hence the total money you will give the delivery boy is $150</em>
