starting at home, nadia traveled uphill to the grocery store for 30 minutes at just 4 mph. she then traveled back home along the

ankoles [38]

Distance from home to store = 4 * 0.5 = 2 miles.
Time taken to return home = (2/12) * 60 =10 minutes.
Total distance traveled = 2 * 2 = 4 miles.
Total time taken = 30 + 10 = 40 minutes.
Average speed for entire trip = total distance / total time in hours.
$Average\ speed=\frac{4}{\frac{40}{60}}=\frac{4\times60}{60}=6\ mph$

Mamont248 [21]

Answer:

Step-by-step explanation:

50 + 12.50h = 143.75....where h = # of hrs

12.50h = 143.75 - 50

12.50h = 93.75

h = 93.75 / 12.50

h = 7.5 (or 7 1/2) hrs <====

How to do questions 19 and 20

Alexeev081 [22]

Answer & Step-by-step explanation:

Using the information given in the question we can form the following 3 equations (in the order of the first 3 sentences)

w = 2h (twice the price)

t = h - 4 ($4 less)

3w + 2h + 5t = 136 (total purchasing and cost)

We can solve all 3 equations for h first, by substituting the first two equations, into the third equations w and t

3(2h) + 2h + 5(h-4) = 136

Simplify

6h + 2h + 5h - 20 = 136

13h = 136 + 20

13h = 156

h = 156/13

h = $12

Using this information, we can solve for w and t

w = 2h

w = 2(12)

w = $24

And finally

t = h - 4

t = 12 - 4

t = $8

Share 800 in the ratio 9:7.

bulgar [2K]

<u>Answer:</u>

The numerator '9's share is 450 and the denominator '7's share is 350.

<u>Step-by-step explanation:</u>

<u>Step-1: Add the ratios:</u>

9 + 7
16

<u>Step-2: Divide 800 by the sum of the ratios:</u>

800 ÷ 16
=> 50

<u>Step-3: Multiply 50 with each ratio:</u>

9 x 50 = 450
7 x 50 = 350

Hence, <u>the numerator '9's share is 450 and the denominator '7's share is 350.</u>

Hoped this helped.
