Use PEMDAS.

P = Parentheses

E = Exponent

M = Multiplication

D = Division

A = Addition

S = Subtraction

This is the order of operations.

For example, let's take the second equation.

36 / 6 + 10 * 66

There are no parentheses or exponents.

So, first we multiply.

36 / 6 + 660

Then we divide.

6 + 660

Then we add.

666

So the equation equals 666.

What is the quotient written in scientific notation? 6 x 10^24 /8 x 10^8

Artist 52 [7]

When you divide 6x10^24 by 8x10^8 you end up with $\frac{6}{8} x10^{16}$

This simplifies to $0.75x10^{16}$

Now this number is not written in scientific notation as it does not have its first digit before the decimal, so we must move the decimal of this one to the right.

To do that you must multiply the number by 10.

This means that the exponet of 10 must decrease by 1.

This makes the answer $7.5x10^{15}$

Find an equation of the line that is perpendicular to the graph of 2x+5y=5 and contains the point of intersection of the graphs

gavmur [86]

Answer:

5(x+1) -2(y-3) = 0

Step-by-step explanation:

For a given line ax+by=c and point (h, k), a perpendicular line through the point can be written as ...

b(x-h) -a(y-k) = 0

A graphing calculator shows the point of intersection of the graphs of the two lines to be (x, y) = (-1, 3), so the line perpendicular to 2x+5y=5 through that point can be written ...

5(x+1) -2(y-3) = 0

_____

In the attached graph, the requested line is shown in black.

A recipe calls for 2 1/2 cups of sugar. You have 2 2/3 cups of sugar. Do you have enough sugar? If not, how much more sugar is n

Karo-lina-s [1.5K]

The difference between the cups of sugar is 1/6, hence you have enough sugar.

<h3>Difference and sum of fractions</h3>

Fractions are written as a ratio of two integers, For instance, a/b is a fraction where a and b are integers.

According to the question, a recipe calls for 2 1/2 cups of sugar. If have 2 2/3 cups of sugar;

Difference of cups of sugar = 2 2/3 - 2 1/2

Convert to improper fraction

Difference = 8/3 - 5/2

Difference = 16-15/6

Difference = 1/6

Since the difference between the cups of sugar is 1/6, hence you have enough sugar.
