If 4 boxes of apples weigh 75.6 lb, how much do 8.5 boxes of apples weigh?

Elena-2011 [213]

Answer:

160.65 lbs.

Step-by-step explanation:

In order to answer this question, we can find the unit weight of each box. In order to do that, we have to divide the amount of weight of the 4 boxes by 4:

75.6 / 4 = 18.9

So, each box of apples weighs 18.9 lbs. Now, we can multiply this unit weight by 8.5 to get the answer:

18.9 * 8.5 = 160.65

And your answer is 160.65 lbs.

Hope this helps ! :)

Need help ASAP math

givi [52]

Answer:

C

Step-by-step explanation:

We know it's direct variation using the direct variation equation.

$y=kx$

Where k is the constant.

Since 7 times x is the y values, $k=7$

Now we can substitute 7 into k of the direct variation equation.

$y=7x$

A parachutist falls at a speed of about 12 miles per hour. Find this speed in feet per second

padilas [110]

So in 1 hour, the parachutist will fall 12 miles or
12 mi/1hour

convert
1 hour=60 mins
1 min=60 seconds
1 hour=60 times 60 seconds=360 seconds
12 miles per 360 seconds

convert miles to feet
5280 feet per mile
12 miles times 5280=63360 feet

63360/360
do the math and simplify
63360/360=6336/36=176

176 feet per second

The inequality of the graph

fiasKO [112]

Answer:

$\displaystyle y > 4x - 2$

Step-by-step explanation:

Starting from the y-intercept of $\displaystyle [0, -2],$ you do $\displaystyle \frac{rise}{run}$ by either moving four blocks south over one block west or four blocks north over one block east [west and south are negatives]. Next, we have to determine the types of inequality symbols that are suitable for this graph, which will be less than and greater than since this is a dashed line graph. We then use the zero-interval test [test point (0, 0)] to ensure whether we shade the opposite portion [portion that does not contain the origin] or the portion that DOES contain the origin. At this step, we must verify the inequalities as false or true:
