Answer: 480

Step-by-step explanation:

Since we know that after two hours Ernie travelled 192 miles, we need to find the miles for one hour. We can find this by dividing the miles by the number of hours travelled so far. 192/2 = 96. We now know that Ernie travels 96 miles an hour. In order to calculate it for 5 hours, we need to times the 96 by 5. 96 * 5 = 480. Ernie travelled 480 miles in 5 hours.

Janelle graphed a line through (−6, 5) that had a slope of −79. What is the y-coordinate of a point on the line that has an x-co

jeyben [28]

Answer:

The value of the y-coordinate is -706

Step-by-step explanation:

The equation of a straight line is;

y = mx + c

where m is slope and c is t-intercept

Given the slope, we can write the equation as;

y = -79x + c

we need to get c

Just put in the x and y values of the given point

X = -6 and y = 5

5 = -79(-6) + c

5 = 474 + c

c = 5-474 = -469

So the complete equation of the line would

be ;

y = -79x - 469

To get the y-coordinate of the point, just insert the x value into the equation;

y = -79(3) - 469

y = -237 - 469 = -706

How do you work out this problem, step by step please I am so lost. Year Average Household Income (before taxes) Food Housing Tr

Hitman42 [59]

Answer:

(a)Food-12%

9b)Transportation-17%

Step-by-step explanation:

In the Year 2000

Average Household Income (before taxes)=$44,649
Amount Spent on Food =$5,158
Amount Spent on Transportation=$7,417

Therefore:

(a)Percentage of the average household income in 2000 was spent on food

$=\dfrac{5158}{44649} \times 100\\\\=11.55\%\\\\\approx 12\% $(to the nearest percent.)$

(b)Percentage of the average household income in 2000 was spent on transportation

$=\dfrac{7,417}{44649} \times 100\\\\=16.6\%\\\\\approx 17\% $(to the nearest percent.)$
