CAN ANYBODY HELP ME OUT
bija089 [108]

Answer:

Correct option is

b. If two sides and one included angle are equal in triangles PQS and PRS, then their corresponding sides are also equal.

Step-by-step explanation:

Here, we are given the line RQ, which is divided in two equal parts by a line PS which is perpendicular to RQ.

The foot S of PS is on the line RQ.

First of all, let us do a construction here.

Join the point R with P and P with Q.

Please refer to the attached image.

Now, let us consider the triangles  PQS and PRS:

  • Side QS = RS (as given)
  • \angle PSR = \angle PSQ = 90^\circ
  • Side PS = PS (Common side in both the triangles)

Now, Two sides and the angle included between the two triangles are equal.

So by SAS congruence we can say that \triangle PRS \cong \triangle PQS

Therefore, the corresponding sides will also be equal.

RP = QP

RP is the distance between R and P.

QP is the distance between Q and P.

Hence, to prove that P is equidistant from R and Q, we have proved that:

b. If two sides and one included angle are equal in triangles PQS and PRS, then their corresponding sides are also equal.

Xavier is testing different types of planting soil to determine which type is most effective in growing blueberry bushes. He pur
vladimir1956 [14]

Answer:

He did not control for lurking variables and their impacts on the results of his experiment. Amount of sunlight and water received are two outside variables(or confounding variables) that may impact the growth of his plants and influence the results. He needs to apply the same amount of sunlight and water to each plant within a different planting soil in order to rule out the influence of those two variables and test the sole effect of the soil brand on the plant growth. Otherwise, it would be hard to determine whether his plant growth was because of the soil brand or the different amounts of sunlight and water received

Select the points that are solutions to the system of inequalities. Select all that apply
Nana76 [90]

Answer:

(-10, 10) and (0,10).

Step-by-step explanation:

For a point to be a solution to the system of inequalities, you will need to see which of the points falls into the shaded area.

When we test out each of the points, we can see that only:

(-10, 10) and (0,10) fall into the blue-shaded area.

A penguin walks south it completes the first 1/3 mile in 1/5 hour and continues walking at the same rate. What is the penguins s
vitfil [10]

Answer:

1.67miles/hour

Step-by-step explanation:

Speed of the penguin = Distance/Time taken

Given

Distance = 1/3 mile

Time = 1/5 hour

Substitute the given data into the speed formula;

Speed = (1/3)/(1/5)

Speed = 1/3 * 5/1

Speed = 5/3

Speed = 1.67miles/hour

Hence the penguin speed in mi/hr is 1.67mi/hr
