All we need to do is multiply.

6 miles * 28 days = 168 total miles ran in 28 days.

Therefore, the answer is 168 miles

Best of Luck!

Annie writes the numbers 1 through 10 on note cards. She flips the cards over so she cannot see the number and selects three car

Kay [80]

<h2>The probability that Annie has selected the cards numbered 1, 2, and 3 is $(\frac{1}{720} )$ </h2>

Step-by-step explanation:

Here, the total number of cards in the set = 10

The cards are numbered as 1,2,3,4,5,...., 10

P(Any event E) = $\frac{\textrm{Total favorable events}}{\textrm{Total number of events}}$

P(picking a card with number 1) = $\frac{\textrm{Total cards with number 1 on it}}{\textrm{Total cards}} = (\frac{1}{10})$

Now when the first card is picked, the number of cards left = 10 - 1 = 9

P(picking a card with number 2) = $\frac{\textrm{Total cards with number 2 on it}}{\textrm{Total cards}} = (\frac{1}{9})$

Similarly, P(picking a card with number 3) = $\frac{\textrm{Total cards with number 3 on it}}{\textrm{Total cards}} = (\frac{1}{8})$

So, the total probability that she has selected card with number 1, 2 and 3

= $(\frac{1}{10} ) \times (\frac{1}{9} ) \times (\frac{1}{8} ) = (\frac{1}{720} )$

Hence, the probability that she has selected the cards numbered 1, 2, and 3 is $(\frac{1}{720} )$

Can someone plsss help me with the circled question tysm if u doo :((

nika2105 [10]

Answer:

4×sqrt(5) inches

Step-by-step explanation:

Pythagorean theorem states that (for right triangles) if you square each shorter side and add those together, you will get the sum of the longest side (hypotenuse) squared.

This is commonly written as:

a^2 + b^2 = c^2, where c is the hypotenuse.

((For right triangles this will always be opposite the 90° angle.))

Since you know one of the shorter sides and the hypotenuse, rewrite the equation as such:

c^2 - b^2 = a^2, where a is the unknown length

This goes to:

sqrt(c^2 - b^2) = a

sqrt((12in)^2 - (8in)^2) = a

sqrt(144sqin - 64sqin) = sqrt(80sqin) = a

This simplifies to:

sqrt(16sqin)×sqrt(5sqin) = 4in×sqrt(5sqin) = a

Help! Write the equation of the line parallel to the given line that passes through the given point in slope intercept form! *ig

Kay [80]

First let's get the equation 2x - y = -4 into slope intercept form. To do this first subtract 2x to both sides:

2x - 2x - y = -4 - 2x

0 - y = -4 - 2x

-y = -4 - 2x

Y still isn't completely isolated, it still has the negative attached to it. To get rid of the negative divide both sides by -1

-y / -1 = (-4 - 2x) / -1

y = 4 + 2x

y = 2x + 4

slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

For a line that is parallel to y = 2x + 4 and passes through point (2, 5) you will need to have the same slope (2)

This is the formula we know so far for the line parallel to y = 2x + 4:

y = 2x + b

Now we must find b

To do that you must plug in the point the line goes through ( 2, 5) in the x and y of the equation.

5 = 2(2) + b

5 = 4 + b

Now solve for b by subtracting 4 to both sides

1 = b

y = 2x + 1

^^^This line is parallel to 2x - y = -4 and goes through the point (2, 5)

Hope this helped!
