Here is your answer:

$\frac{7}{30} + \frac{9}{20}$
Find common denominator:
$30 \times 20 = 60 /20 \times 30 = 60$
Common denominator is 60:
$\frac{7}{30} + \frac{9}{20} = \frac{140}{60} + \frac{270}{60}$
$140 + 270 = 410$
$= \frac{410}{60}$
$\frac{410}{60} \div 2 = \frac{205}{30} \div 5 = \frac{41}{6}$
= $\frac{41}{6} or 6\frac{5}{6}$

Hope this helps!

Answer:

A) 2

Step-by-step explanation:

Start off with the given information. The question states that the x-int. is 4, so you should recognize that there is a point at (4,0). Plug the point into the equation.

k(4) + 2(0) + 8 = 0

Now simplify the equation.

4k + 0 + 8 = 0

Isolate the variable, make sure it's on its own side.

4k = 8

Now get the k by itself to solve the equation. Divide both sides by 4.

k = 2

R=x^2/y <br> x=3.8 times 10^5 <br> y=5.9 times 10^4 <br> work out the value of r

Answer:

2.4×10^6

Step-by-step explanation:

Put the numbers where the variables are and do the arithmetic. You can enter the numbers in scientific notation into your (scientific) calculator and have it show you the result in the same format.

r = (3.8×10^5)^2/(5.9×10^4) . . . . . denominator parentheses are required

Please note that in the above expression, parentheses are required around the denominator number. This is because it is a product of two numbers. In your pocket calculator or spreadsheet, you can enter that value as a single number (not a product). Parentheses are not required when you can do that.

r = (3.8²/5.9)×10^(5·2-4) ≈ 2.4×10^6

___

The "exact" value is a repeating decimal with a long repeat. We have rounded to 2 significant digits here because the input numbers have that number of significant digits.
