Answer:

The ratio is 1:35 and the equivalent fraction is 2/70.

Step-by-step explanation:

It is given that, there is 1 principal to every 35 teachers.

It means that the ratio of principal to teachers is 1:35.

It can be also written as 1:35=\dfrac{1}{35}

For equivalent fraction multiply both numerator and denominator by 2. So,

\dfrac{1}{35}=\dfrac{1\times 2}{35\times 2}\\\\=\dfrac{2}{70}

Hence, the ratio is 1:35 and the equivalent fraction is 2/70.

Calculate the value of b.<br>(b-15)<br>3b°<br>(2b + 45°<br>Diagram not drawn accurately​
e-lub [12.9K]

Answer:

b = 30

Step-by-step explanation:

The sum of the 2 angles above the line will equal the angle below the line

3b + b - 15 = 2b + 45

4b - 15 = 2b + 45 ( subtract 2b from both sides )

2b - 15 = 45 ( add 15 to both sides )

2b = 60 ( divide both sides by 2 )

b = 30

Look at this graph:
kvasek [131]

Answer:

The slope is 4 or 4/1.

Step-by-step explanation:

Since these are all in numbers evenly divisible by 10, we can go ahead and make this easier by dividing everything by 10. When we do this, we can see a point crossing an intersection at (3,1), or if you left it, (30, 10). Next, we can see another point crossing another intersection at (4,5) or (40, 50). Since we have two points that are easy for us to subtract, we can use the slope formula. The formula is as follows: y2-y1 / x2-x1. We can pick which of these we want to be 1 or 2, but whichever one we pick has to be 1 or two on both the top on the bottom. for example, I did (50-10) / (40-30). That gets us 40/10. If you divided by ten in the first place, you would get 4/1. From there, if you have the bigger answer, you need to simplify to simply 4. The shorter answer doesn't need to be simplified because we already simplified. I hope this helps!

Together teammates pedro and ricky got 2685 base hits last season. Pedro had 277 more than ricky. How many hits did each player
Ksju [112]
Let x be the number of base hits Ricky got. With this representation, the number of base hits Pedro got is x + 277. The sum of their number of hits is equal to 2685. The equation that best represent the scenario is,
                                   x + x + 277 = 2685
The value of x is 1204. Therefore, Ricky got 1204 and Pedro got 1481.
