A. 5 minutes
B. 4 minutes
C. 3 minutes
D. 13 minutes

Answers

Answer 1
Answer:

Answer:

A. 5 minutes

Step-by-step explanation:

We can solve this question using proportions

Let x be the number of minutes needed to type 225 words.

8 minutes = 360 words

     x          = 225 words

Cross-multiply

360 × x  =  225× 8

360 x = 1800

Divide both-side of the equation by 360

(360x)/(360)  = (1800)/(360)

(On the left-hand side of the equation, 360 at the numerator  will cancel-out 360 at the denominator, while on the right-hand side of the equation 1800 will be divided by 360)

x= 5 minutes

Therefore, it will take 5 minutes to type 225 words
Answer 2
Answer:

Well, it cant be option B because then it wuld be half the time (180 mins.)

It cant be option D becasue then it would be over 360 mins, seeing that it only took 8 mins to type 360

And it cant be option C beacuse it would be too small, if 4 mins is to small then 3 mins is worse

Your answer would be A 5 minutes it's just a little bit above 4 mins(half)

Solve the literal equation for the given variable. A= bh/2 (bh over 2)
Solve for b. With solution please.

Answers

If I understood your question right, he right equation would be b=2A/h

If A is on the one side of the equation, and bh/2 is on the other side, it means that our goal is to get to the point when b is alone on one side of the equation, doesn't matter which. 

When working with equations like this, always remember that if X is the number that you divide by on one side, when you transfer it to the other side of the 'equal' sign it is going to switch is function and become a multiplier. So, in this case, when we transfer the number two on the other side it is going to become 2xA and we will have left 2 x a=b x h.

To get b alone, as we wanted to, we will transfer h on the other side and it will become the divider, adn we will get the solution: 2A/h=b 

Hope this helps :)

What is the distance between the points (–8, –2) and (–7, –2)? A.
1

B.
6

C.
10

D.
15

Answers

easy, since the y coordinat didn't change, y didn't move
only x moved
we just see how far x moved
-8 to -7
that is 1 distance

or ou could use distance formula

the distance between the points
(x1,y1) ad (x2,y2) is
D=\sqrt{(x2-x1)^(2)+(y2-y1)^(2)}
points are
(-8,-2) and (-7,-2)
D=\sqrt{(-7-(-8))^(2)+(-2-(-2))^(2)}
D=\sqrt{(1)^(2)+(0)^(2)}
D=√(1+0)
D=√(1)
D=1

answe ris A
a=1
