Answer:

d=45.25h

Step-by-step explanation:

This constant motion is represented by:

d=st

Where d is distance, s is speed and t is time.

We know that in 2 hours they travel 90.5 miles, this gives us a speed of:

s=\frac{d}{t}=\frac{90.5}{2}mi/hr=45.25mi/hr

But, the problem is asking for a general expression:

d=st\\d=\frac{90.5}{2}t\\ d=45.25h

Therefore, they travel a distance d in h hours, according to the expression

d=45.25h

Answer:

The correct option is C

Step-by-step explanation:

A: We know that the lower quartile is 144, and the upper quartile is 129.5 is you add them all up it is going to equal 273.3. So we know that A can now be crossed out.

B: We know that the lower quartile is 146, and that means the upper quartile is 136.5. So adding all of these numbers up we ill get 282.5 So now <u>B can be crossed out</u>

C: The lower quartile is 114 and the upper quartile is 129.5 and when we add those two numbers up we are going to get 243.5. So we are going to keep this number

D: For the last one we know the lower quartile is 214 and upper is 129.5, and when we add this we get 343.5. So we can cross this out and<u> the only one we have left is going to be C</u>

<u>Hope this help's</u>

WILL MARK BRAINLIST!!What is the measure of one interior angle in a regular pentagon?
never [62]
The answer is 108°

A regular pentagon has all its five sides equal and all five angles are also equal. Hence, the measure of each interior angle of a regular pentagon is given by the below formula. Measure of each interior angle = [(n – 2) × 180°]/n = 540°/5 = 108°.

Triangle DEF is circumscribed about circle R. Points S, T and U are points of tangency where SD = 4 m and UF = 7 m. What is the
Mama L [17]
The measure off DF is 11.

In a circle inscribed within a triangle, the distance from each vertex of the triangle to the two nearest touchpoints (points of tangency on the circle) are equal.  Since SD=4, DT=4 as well.  Since UF=7, then FT=7.  

DF=DT+TF=4+7=11.
