Answer:

13km

Step-by-step explanation:

Given data

Time= 8 days

Speed= 2 1/6 kilometers per day = 13/6 kilometers per day

Distance= ??

We know that

Speed= distance/time

therefore, Distance= speed*time

substitute

Distance= 13/6*8

Distance= 104/8

Distance= 13 km

Hence the crew did 13km

Find the equation of the line<br> passing through the points (5, 2)<br> and (10, 6).<br> y =<br> Xt
Natalka [10]

Answer:

y=4/5x-2

Step-by-step explanation:

here are the given points: (5,2) and (10,6)

First, let's find the slope, which is found with the equation (y2-y1)/(x2-x1)

so let's label the points

x1=5

y1=2

x2=10

y2=6

now we can substitute into the equation

m=(6-2)/(10-5)

subtract

m=4/5

so that means the slope is 4/5

Now, let's use point slope form, which is y-y1=m(x-x1) (m is the slope)

so let's substitute the numbers we know from earlier into the equation

y-2=4/5(x-5)

do distributive prop.

y-2=4/5x-4

add 2 to both sides

y=4/5x-2

hope this helps!

a crane cable can support a maximum load of 15,000 kg. if a bucket has a mass of 2,000 kg and gravel has a mass of 1,500 kg for
Brut [27]
2000 + 1500g ≤ 15000
1500g ≤ 15000 - 2000
1500g ≤ 13000
g ≤ 13000/1500
g ≤ 8 2/3

Therefore, the crane can safely lift a maximum of 8 2/3 cubic meters of gravel.

The probability of drawing a black marble from a bag is 1/2, and the probability of drawing a white marble from the same bag is
s344n2d4d5 [400]
<span>W = event where white marble is drawn 
B = event where black marble is drawn 

The two events W and B are independent. This is because the marble taken out on the first draw is put back into the bag. Since W and B are independent, we can use this rule 

P(W and B) = P(w)*P(B) 


Use the rule to get 

P(W and B) = P(W)*P(B)
P(W and B) = (1/2)*(1/4)
P(W and B) = (1*1)/(2*4)

P(W and B) = 1/8 

1/8 is equivalent to 0.125. Use long division or a calculator 

0.125 = 12.5% </span>
