Answer:

A

Step-by-step explanation:

The answer is A because...

  • Step one wen need to multiply the conjugate. So we should have 2 square root of 3 square root of 5/ 3 square root of 5 square root of 5
  • Step two-Then we solve the numerator. 2 square root 3 square root 5= 2 square root 15
  • Step three- Now we solve the denominator 3 square root 5 square root 5 which equals 15
  • Finally we place the numerator over the denominator to get 2 square root
  • It will be easier to understand if you see it in picture so I typed it up for you
  • Hope this helped

Hello there!

So, remember that m = the slope, and slope intercept form is represented as y = mx + b. To find the y intercept, place the values of x, y, and the slope into the equation.

The first step, ____ = (____)____ + b should look like 3 = (2/5)10 + b once you plug the values for your x and y values and slope.

The second step, ___ = ____ + b should look like 3 = 4 + b since you should multiply 2/5 x 10.

The final step, -1 = b should look like  since you subtracted 4 from both sides of the equation.

Y = 2/5x - 1 is your final equation. I hope this helps, have a great rest of your day!

Find the area of the figure.<br><br> plz i give brainliest.
Sonja [21]

Answer:

23.5 inches^2

Step-by-step explanation:

Area of triangle = 1/2 * base * height

area = 1/2 * (5+2) * (5+4)

area = 31.5 in^2

Area of rectangle = length * breadth

area = 4 * 2

area = 8 in^2

Area of figure = area of triangle - area of rectangle

area = 31.5 - 8

area =23.5 in^2

PLEASE HELP!!!!!! I need help on this problem
Thepotemich [5.8K]

Answer:

185 minutes.

Step-by-step explanation:

It is possible to model an equation for this, such that

0.10x + 14.80 = 0.08x + 18.50

where x represents the number of minutes.

Then, you solve for x:

0.10x + 14.80 = 0.08x + 18.50 \\ 0.02x = 3.70 \\ x =  \frac{3.70}{ 0.02}  \\ x = 185

Write an equation for the nth term of the arithmetic sequence. Then find a50.<br> 8, 2, -4, - 10,
AlexFokin [52]
Answer: See below

Explanation:

Write an equation for nth term:

a + d(n - 1)

a = 8 (first term)
d = -6 (common difference)

8 - 6(n - 1)
= 8 - 6n + 6
= -6n + 14

Find a 50:

-6(50) + 14
= -300 + 14
= -286

Suppose Riley is interested in the cost of a gallon of gas in her state. She finds the cost of a gallon of regular gas at 61 ran
hichkok12 [17]

Answer:

The standard deviation of the sample is 0.0064.

Step-by-step explanation:

The standard deviation of a sample of length n of a population with standard deviation \sigma is given by the following formula:

s = \frac{\sigma}{\sqrt{n}}

In this problem, we have that:

61 randomly selected gas stations. This means that n = 61

The standard error of the mean is $0.05. This means that \sigma = 0.05.

What is the standard deviation of the sample?

s = \frac{\sigma}{\sqrt{n}} = \frac{0.05}{\sqrt{61}} = 0.0064

The standard deviation of the sample is 0.0064.
