On a road trip, Maura drove at a speed of 60 miles per hour for the first two hours.she then increased her speed by 25%.

1 answer:

6 0

So Maura was driving 60 miles per hour for two hours. That's 60x2 which equals 120 miles in the two hours she's been driving. After two hours she increases her speed by 25%. 25% of 60 is 15, so she is now going 75 miles per hour (Part A). If she continues to drive this way, the equation would be 75xh=d. 75 being how fast she's going and h being the number of hours she's gone. If you multiple those two together it will give you the distance she's gone (Part B). If you substitute the 5 hours from Part C the equation would be 75 miles multiplied by 5 hours. 75x5= 375 miles.

What is the simplified form of StartRoot StartFraction 72 x Superscript 16 Baseline Over 50 x Superscript 36 Baseline EndFractio

aalyn [17]

Answer:

StartFraction 6 Over 5 x Superscript 10 Baseline EndFraction

Step-by-step explanation:

Apparently you want to simplify ...

$\sqrt{\dfrac{72x^{16}}{50x^{36}}}$

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

1/a^b = a^-b

(a^b)^c = a^(bc)

So the expression simplifies as ...

$\sqrt{\dfrac{72x^{16}}{50x^{36}}}=\sqrt{\dfrac{36}{25x^{36-16}}}=\sqrt{\dfrac{36}{25x^{20}}}\\\\\sqrt{\left(\dfrac{6}{5x^{10}}\right)^2}=\boxed{\dfrac{6}{5x^{10}}}$

A campus radio station surveyed 500 students to determine the types of music they like. the survey revealed that 199 like rock,

Ostrovityanka [42]

There are 24 who like both rock and country. There are 8 who like all 3 types, and these eight have been counted under the 24. This means that the number who like rock and country but not jazz is 24 - 8 = 16.
We are given a total of 155 who like country. We subtract the 16 who like both rock and country, and are left with 139 people who like country but not rock. (It does not matter whether they like jazz or not).
The probability is 155 out of the total of 500, so 155/500 = 31/100 = 0.31.

Which is the correct interpretation of the x-intercepts of

stira [4]

Answer:

The x-intercept would be at the point where there are 0 downloads in x days.

Step-by-step explanation:

The x-intercept of a function is the point where the graph of the function crosses the x-axis and the y-coordinate is 0.

That is, the point (x, 0) is the x-intercept of a function.

In this case the data provided is for the number of free downloads using the promo code (f (x), in tens of thousands) and the time since posting (x days).

So, in this case the x-intercept would be at the point where there are 0 downloads in x days.
