Answer:

138

Step-by-step explanation:

We know that there are at least 3 short sleeved shirts and there are at least 7 long sleeved shirts. And we know it's in that ratio. So the best way to start this is to divide 460 by 7+3 to get the single unit amount of both shirts.

46 is the single unit amount. So 46 * 3 will get us our short sleeved shirts:

46 * 3 = 138

To check our answer, we'll take 460-138 and divide that by 7 to see if we get 46:

322/7 = 46

So the answer is correct!

frutty [35]

Answer:

$m=20n$

Step-by-step explanation:

Let

$A(5,100),B(10,200)$

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$slope=\frac{m2-m1}{n2-n1}$

substitute the values

$slope=\frac{200-100}{10-5}=20$

step 2

Find the equation of the line into slope-point

$m-m1=slope(n-n1)$

with the slope and the point A

$m-100=20(n-5)$

$m=20n-100+100$

$m=20n$

Naomi has earned $54 mowing lawns

lyudmila [28]

Answer:

8 dollar/hr

Step-by-step explanation:

she worked 2 1/2 hrs yesterday and 4 1/4 hrs today

2 1/2 + 4/14

2+4 is 6

and 1/2+1/4 multiply 2 to both numerator and denominator of 1/2 so that the denominator of both fraction is like

it will now become 2/4+1/4 which equals 3/4

This means that she worked total of 6 3/4 hour in all yesterday and today

she is paid 54 dollar

we will need to divide 6 3/4 or written as 6.75 by 54 to find how much she earns per hour

and that would be 8

so she earns 8 dollar per hour.

babymother [125]

Answer:

On average, the project takes 4 weeks to complete.

Step-by-step explanation:

We have these following probabilities:

25% probability that the activity takes 2 weeks.

50% probability that the activity takes 4 weeks.

25% probability that the activity takes 6 weeks.

How long does the project now take to complete (on average)

We multiply each duration by it's probability.

0.25*2 + 0.5*4 + 0.25*6 = 4

On average, the project takes 4 weeks to complete.
