Answer:

(3,2.5)

Step-by-step explanation:

Since the coordinates of A is (1,1) and the coordinates of B is (5,4), the x coordinates of C would be in the middle of 1 and 5, which can be solved by doing (1+5)/2=3. Therefore the x coordinate of C is 3. The same goes for the y coordinate so it would be (1+4)/2=2.5. Therefore the coordinates of C are (3,2.5)

A kilogram of seawater contains 1/40 kg of salt. How much salt is there in two buckets of seawater, which contain 500 liters of

never [62]

Two buckets of seawater contain $13\frac{28}{40}$ kg of salt.

Step-by-step explanation:

Amount of salt in 1 kg water = $\frac{1}{40}\ kg$

It is given that;

1 liter = $1\frac{12}{125} = \frac{137}{125}\ kg$

500 liters = $500*\frac{137}{125} = \frac{68500}{125}$

500 liters = 548 kilogram

As,

1 kg of seawater = $\frac{1}{40}\ kg$ of salt

548 kilograms = $\frac{1}{40}*548$

548 kilograms = $13\frac{28}{40}$ kilograms of salt

Two buckets of seawater contain $13\frac{28}{40}$ kg of salt.

mafiozo [28]

Answer:

$16\ minutes$

Step-by-step explanation:

For every $24\ minutes$ of television time of commercials = $6\ minutes$

% of commercials $\=frac{6}{24}\times 100=25\%$

Now when time of television $=1\ hour\ 36\ minutes=60+36=96\ minutes$

$25 \%\ of 96=\frac{25}{100}\times 96=\frac{96}{4}=16\ minutes$

Linear Functions <br> 7g+3g-10+3=43<br> Step by step solution? <br> Thankss!❤️

Ivahew [28]

7g + 3g - 10 + 3 = 43

(first combine likes terms)

10g - 7 = 43

(then add 7 to both sides)

10g - 7 = 43
+7 +7

10g = 50

(then divide by 10 to get what g is equal to)

10g = 50
/10 /10

g = 5
