Answer:

170 ft^2

Step-by-step explanation:

The surface area of a square prism is 2 times the base area + 4 times the area of a lateral face.

S=2(25)+4(30)

S=50+120

S=170

A study of 218 students at a major state university suggests a link between time spent on social networking websites and grade p

zheka24 [161]

Answer:

a) The study suggests a negative correlation because the study shows that as time spent on social networking websites Increases, grade point average tends to decrease.

b) While it is possible that there is a cause and effect relationship, it is not necessarily the case.

Step-by-step explanation:

Since the study submitted that, students who rarely never used social networking websites had higher grade point averages than students who use social networking websites. It implies a negative relationship. Thus, the option given above is the correct answer.

Similarly, the study might imply some cause and effect relationship but it is not necessarily to be the case. <em>That is, low grade point could result into more time with social networking website. </em><em>This is not necessary to be TRUE!</em>

Consecutive integers are 1,2,3,4 and so on. Consecutive even integers are 2,4,6,8 and so on. The sum of an integer and twice the

antiseptic1488 [7]

the numbers are x=58 & x+2=60 , i.e. 58 and 60 .

<u>Step-by-step explanation:</u>

Here we have , Consecutive integers are 1,2,3,4 and so on. Consecutive even integers are 2,4,6,8 and so on. The sum of an integer and twice the next consecutive even integer is 178. We need to Write and solve an equation to find the two integers. Let's find out:

Let the integer be x , and the next consecutive even integer be x+2 .Now , According to question , The sum of an integer and twice the next consecutive even integer is 178 i.e.

⇒ $x + 2(x+2)=178$

⇒ $x + 2x+4=178$

⇒ $3x+4=178$

⇒ $3x=174$

⇒ $\frac{3x}{3}=\frac{174}{3}$

⇒ $x=58$

Therefore , the numbers are x=58 & x+2=60 , i.e. 58 and 60 .
