~Hello There!~

Anything to a negative power, turns it into 1 over that number.

Therefore 49^{-\frac{1}{2} }  = \frac{1}{49\frac{1}{2} }

Anything to the power of a half, means you have to square root it.

Therefore, the first part is now \frac{1}{7}

When you have a fraction as a power and both numbers are above one:

You must 'root' it by the denominator and put it to the power of the top number.

Therefore, \sqrt[3]{64} = 4

4^{2} = 16

Now we have:

\frac{1}{7} * 16

Simply divide 16 by 7 to get the answer:

2.285714

However, since it is a long number, you can just leave it as \frac{16}{7}

Hope This Helps You!                                                                                      

Good Luck :)                                                                                                      

Have A Great Day ^_^

(a) Write 14 as a decimal.​
Yuliya22 [10]

Answer:

0.14

Step-by-step explanation:

14% describes 14 out of 100. It is written as 14 in the numerator and 100 in the denominator of a fraction. A percent is always written as the number over 100 as a fraction. “Out of 100” refers to the decimal place “hundredths.” 14% is 14 hundredths.

Find X. This is a 40°, 40°, 90° triangle.
sergiy2304 [10]

Answer:

In a 45°−45°−90° triangle, the length of the hypotenuse is √2 times the length of a leg. To see why this is so, note that by the Converse of the Pythagorean Theorem , these values make the triangle a right triangle. Note that an isosceles right triangle must be a 45°−45°−90° triangle.

a snack cart sells lemonade for $2 and hot dogs for $5. the vendor sold 86 items today for a total of $330.which equation is tru
DaniilM [7]
There are two equations in the system of equations in this problem.
Let x = lemonade and y = hot dogs

First equation
x + y = 86
This says that the total sold hot dogs and lemonades add up to 86 sold.

Second equation
2x + 5y = 330
This says that $2 for each lemonade, $5 for each hot dog. The total amount earned is $330.

Only these two equations are true and needed.
