Mavis drives = 634 miles.

Mavis visits her grandmother 4 times.

That means, she drives 634 miles each time when she visits her mother.

One time round trip Mavis's house to her gramdmother in philadelphia = 634 miles.

If she visited 4 times, we can multiply one round trip distance by 4 or we can just add that distance four times.

Let us try it by multiplying 4 by 634 .

If we multiply 4 by 634, we get 2536.

Therefore, 2536 miles Mavis drives if she visits her grandmother 4 times.

Solve the right triangle shown in the figure BC = 1.6in< A=48.8 C =90
yKpoI14uk [10]
Drawing a diagram to represent the information you've given, the only angle we are missing is B.  We can find that by subtracting the two we're given from 180:
180 - 90 - 48.8 = 41.2
<em>m</em>∠<em>B</em> = 41.2°.
We can use the angles and the one side we're given to find the remaining sides.  Since we do not know the length of the hypotenuse, AB, we cannot use sine or cosine.  We must use tangent (the ratio for tangent is opposite/adjacent):
\tan 41.2 = \frac{x}{1.6}
Multiply both sides by 1.6:
1.6 \tan 41.2 = x&#10;\\ 3.67 = x
This is the length of side AC, which is opposite to angle B.
To find the length of AB we can use the Pythagorean Theorem:
(1.6)^2+(3.67)^2=c^2&#10;\\ 2.56+13.4689=c^2&#10;\\ 16.0289=c^2&#10;\\ \sqrt{16.0289} = \sqrt{c^2}&#10;\\ 4=c
The length of side AC, the hypotenuse, is 4 inches.

What is the solution to -41-2x + 6 = -24?
xeze [42]

Hello!

-41 - 2x + 6 = -24 <=>

<=> -35 - 2x = -24 <=>

<=> -2x = -24 + 35 <=>

<=> -2x = 11 <=>

<=> x = -11/2 or -5.5

Good luck! :)

For the question: "My quadrilateral has a pair of equal sides and a pair of parallel sides, what special type my quadrilateral m
Effectus [21]

Answer:

Step-by-step explanation:

It must be a trapezoid because a trapezoid has at least one set of parallel sides.  Sides of equal length don't mean anything really unless we know hose sides are parallel.  I will say sometimes I hear trapezoids ONLY have two parallel sides, while the other two are not, while in other places as long as two are parallel it is a trapezoid.  It looks like for this question it is using the definition that at least two parallel sides makes it a trapezoid.

it can be an isosceles trapezoid since it is a type of trapezoid,  same with right trapezoid.  Basically any special kind of trapezoid

parallelogram because it can have two pairs of parallel lines and have thos parallel sides be equal.  So this also means it can be all kinds of parallelograms.  

Do you have a list to choose from?  because most I pull up don't include right trapezoid at least.

This leaves kite as the only kind of quadrilateral to look at yet, and it specifies no parallel sides. bt your shape need at least one set of them, so it cannot be a kite.

The number of potholes in any given 1-mile stretch of freeway pavement in Pennsylvania has a Normal distribution. This distribut
Iteru [2.4K]

Answer:

83.85% of 1-mile long roadways with potholes numbering between 22 and 58

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 49

Standard deviation = 9

Using the Empirical Rule, what is the approximate percentage of 1-mile long roadways with potholes numbering between 22 and 58?

22 = 49 - 3*9

So 22 is three standard deviations below the mean.

Since the normal distribution is symmetric, 50% of the measures are below the mean and 50% are above the mean.

Of those 50% which are below the mean, 99.7% of those are within 3 standard deviations of the mean, that is, greater than 22.

58 = 49 + 9

So 58 is one standard deviation of the mean.

Of those which are above the mean, 68% are within 1 standard deviation of the mean, that is, lesser than 58.

Then

0.997*0.5 + 0.68*0.5 = 0.8385 = 83.85%

83.85% of 1-mile long roadways with potholes numbering between 22 and 58
