Answer:

4777.28 N

Step-by-step explanation:

The gravitational force down the slope is given by the formula;

(mass *g * sin θ )  

where;

θ is the angle of inclination of the slope

g is the gravitational pull

We plug in the given values into the above expression;

(4,000 x 9.8 x sin 7) = 4777.28 N.  

The frictional force must equal to 4777.28 N (pointing up the slope).

devlian [24]

Answer: 299

Given

Family removes one-third of tress in June as much as they dd in July

They remove twice the number of July in august

Suppose they removed x trees in July

for June it is, \frac{x}{3}

for August, it is 2x

If they removed less than 1000 tress in 3 months

\Rightarrow \dfrac{x}{3}+x+2x

So, maximum number of tress removed in July is 299

The lizards in the show eats about 200 crickets per week.About how many crickets do they eat each day.
bogdanovich [222]

Since there are 7 days in a week, you divide 200 and 7 to get 28.57.

You must also round to the nearest integer, so the lizards in the shows eat about 29 crickets each day.
