Answer:

x is 100 and y is 40

First make 500 into a number where it can be divisable by 3. 5x40=200

500-200=300, 300 divided by 3 equals 100

pav-90 [236]

Answer:

Step-by-step explanation:

a1 = 51 + (1 -1 ) * 0.8

a1 = 51

a2 = 51 + (2 - 1)*0.8

a2 = 51 + 0.8

a2 = 51.8

a3 = 51 + (3 - 1)*0.8

a3 = 51 + 2*0.8

a3 = 51 + 1.6

a3 = 52.6

a4 = 51 + (4 - 1)*0.8

a4 = 51 + 2.4

a4 = 53.4

gogolik [260]

Answer:

925 marks.

Step-by-step explanation:

AS Biraj had 20 less marks then the 40% pass mark must be 350+20 = 370.

370 is equivalent to 40%

So 100% = 100*370 / 40

= 925 marks.

You are drawing a map. Two cities on the map are 7 inches apart. You know the actual distance between them is 1,750 miles. What

swat32

Answer:

1 inch : 250 miles
1/15,840,000

Step-by-step explanation:

Map scale factors are usually written a couple of different ways. One of them is the number of miles represented by 1 inch. Here, that is ...

1750 mi/(7 in) = 250 mi/in

Written that way, the scale factor is 1 in : 250 miles.

The other way the scale factor can be written is as a unitless ratio. That ratio is ...

$\dfrac{1\,\text{in}}{250\,\text{mi}}\times\dfrac{1\,\text{mi}}{5280\,\text{ft}}\times\dfrac{1\,\text{ft}}{12\,\text{in}}=\dfrac{1}{250\cdot 5280\cdot 12}=\dfrac{1}{15,840,000}$

The map scale factor is 1 in : 250 miles, or 1/15,840,000.

Elena-2011 [213]

Answer:

It will cost $700 to play the entire schedule.

Step-by-step explanation:

Given : $N(x)=x^2-x$

To Find : A softball league has 5 teams, each of which play the others twice. If the league pays $35 per game, how much will it cost to play the entire schedule?

Solution:

Equation for total no. of games when all the teams play each other twice is $N(x)=x^2-x$

Now we are given that A softball league has 5 teams, each of which play the others twice.

So, Substitute x = 5 in the given equation

$N(x)=5^2-5$
