Answer:

Step-by-step explanation:

2/5min=24 sec

5 min=300 sec

total=324 seconds

the water decreased 100-19=81 degrees

81/324=0.25 degrees/second

the change in temperature was 0.25 degrees per second

we will multiply by 60

15 degrees per minute

(x_{m},y_{m} )  = (\frac{X_{A} +X_{B} }{2}  ,\frac{Y_{A} + Y_{B} }{2})

(x_{m},y_{m} )  = (\frac{5-1}{2}  ,\frac{8-4 }{2})

(x_{m},y_{m} )  = (\frac{4}{2}  ,\frac{4 }{2})

(x_{m},y_{m} ) = (2, 2)

Need help with two word problems
dangina [55]

Answer:

E. 18 children are buying their lunches

F. Rock must pay $50 each month

Step-by-step explanation:

E.

To find a percentage you multiply the number by the percentage;

60 x 70%(0.70) = 42 children brought their lunches

But we need the amount <u>buying</u> their lunches so we would subtract 60 by 42;

60 - 42 = 18 buying their lunches

F.

Again, to find the percentage we multiply it by the original;

$800 x $25(0.25) = $200 Rock paid for the down payment on the sofa

Now we need to find how much Rock still needs to pay for the sofa;

$800 - $200 = $600 more needed to pay for the sofa

Lastly, we must find how much Rock will need to pay <u>each month</u> to pay the rest of the $600. There are 12 months in a year, so we divide that by the amount left;

$600 / 12 = $50 needs to be paid each month for a year

leonid [27]
The line goes 3 right for every 1 down, so the gradient is -1/3
The y-intercept is +4, so the equation is actually y=-1/3x+4, so Chris is wrong.
