The answers are A and C
PS you should give me the brainliest andswer
Hi
You have two points A ( X;Y) and B ( X ; Y)
slope is : ( Yb -Ya) / (Xb -Xa )
A (1; -8) B ( -5 ; 10)
so : ' (10 - -8 ) / ( -5 - 1) = 18 /-6 = -3
130,000/500=216.
1 hour per 500 gallons.
500 times x =130,000.
500 gallons in 216 hours will complete the drainage.
216-125=135.
It will take 135 more hours to drain the pool.
please make brainliest!
Answer:
Speed = 3.75 miles per hour.
Step-by-step explanation:
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;
<u>Given the following data;</u>
Distance, d = 3/4 miles
Time, t = 1/5 hour
<em>Substituting into the equation, we have;</em>
Speed, S = 3.75mph.
<em>Therefore, Josie's speed is 3.75 miles per hour. </em>
The sum of the measures of the angles of a polygon is given by (<em>n</em> - 2)(180), where <em>n</em> is the number of sides. In this case we would have (9-2)(180)=7(180)=1260. This is the <u>sum</u> of the angles. Since it is a regular nonagon, that means that all sides are congruent and all angles are congruent. Therefore we find the measure of each individual angle by dividing the sum, 1260, by the number of sides, 9. 1260/9=140. <em>x</em> forms a linear pair with one of the interior angles; that means that the interior angle, 140, added to <em>x</em> would give us 180. Therefore we find <em>x</em> by subtracting 180-140. <em>x</em> = 40.
