3.) yes
4.) yes
5.) yes
Answer 2

Answer:

1. correct

2. not correct

3.correct

4.correct

5. not correct

6. correct

Step-by-step explanation:

P(parenthesis) E(exponents) M(multiplication) D(division) A(addition) S(subtraction)

You first solve what is in the parenthesis (if there is any) than make your way down this list IN ORDER until you hit subtraction.

1.

[tex](8+7)/3=5\\\\(15)/3=5\\5=5[/tex]

2.

(4 × 5) − 3 = 8

Parenthesis first

(20)-3=8

subtract

17=8

3.

(4 × 5) − 3 = 17

Do what is in parenthesis first

(20)-3=17

subtract

17=17

4.

14 − 7 × 2 = 0

Multiply 7*2 first

14-14=0

subtract

0=0

5.

14 − 7 × 2 = 14

Multiply 7*2 first

14-14=14

subtract

0=14

6.

12 + (7 + 9) = 28

Parenthesis first

12+(16)=28

Add

28=28

Holden is trying to determine the velocity of his race car. He went 20 meters east, turned around, and went 40 meters west. His car was 20 meters from the starting line. This took 5 seconds.

What is the car’s average velocity?

4 m/s east
4 m/s west
12 m/s west
12 m/s east

Answers

Answer:

4 m/s west

Step-by-step explanation:

Because he went only 20 meters east and then went 40 meters west, he would be going west. Then when you divide the displacement, which you get by subtracting the 2 numbers, by 5 seconds, you get 4 m/s. I'm sorry if I'm wrong.

answe is four m west

Given a circle with measures of (C, d, and r) and a circle with measures of (C', d', and r'), find r' if C/C' = 0.25 and d = 6.0.

Answers

Answer:

12, r' is 12

Step-by-step explanation:

c/c' = 0.25, so c' is 4 times as much as c, the second circle is 4 times  bigger than the first. So r' is 4r, we know that d = 6, and r is 1/2 of d, so r = 3, r' is 4r, so r' is 12

Answers

3 would be 53. Since the lines are parallel the angles will be the same

4 would be 47 because of outer exterior angles

Answer:

so basically these angles in the first pictures would be the same so it would equal 53 degrees and in the second picture they would also be the same so 47 degrees. is the angles dont look the same then youd subtract the number you have from 180 and that would equal up too the next angle but if your angles look like the same they will be.

2 over 1 is just 2.

Answer:

I think the answer(s) are m = -3 and/or m = 1.5 because they both hit the lines.

(sorry if I'm wrong or this wasn't helpful)

Step-by-step explanation:

Three ways to find the slope of a line:

1. You may have two points  ( x 1 , y 1 )  and  ( x 2 , y 2 )  (often one or both of these points may be intercepts of the  x  and/or  y  axes). The slope is given by the equation  

          y 2 − y 1 [tex]\frac{}{}[/tex]

m  =  --------------                   (<- that's supposed to be a fraction btw)

          x 2 − x 1

2. You may have a linear equation that is either in the form or can be manipulated into the form

y  =  m x + b .

In this case the slope is  m  (the coefficient of  x ).

3. If the line is a tangent to another function, you may have (or be able to determine) the slope of the tangent as the derivative of the function. Normally in this case the derivative is a function expressed in terms of  x  and you need to substitute the value of  x  into this function for the required location.
