What is the midpoint of the segment shown below?
aleksandr82 [10.1K]

Answer:

Mid\ points = (\frac{5}{2} , \frac{7}{2}).

Step-by-step explanation:

Given : End points of line are (3, 5) and  ( 2 , 2) .

To find : What is the midpoint of the line .

Solution : We have given

End  points(3, 5) and  ( 2 , 2) .

Mid\ points = (\frac{x_{1}+x_{2}}{2} , \frac{y_{1}+y_{2}}{2}) .

Here ,

x_{1} = 3.\\x_{2} = 2.\\y_{1} = 5.\\y_{2} = 2.

The plug the values in given formula.

Mid\ points = (\frac{3+ 2}{2} , \frac{ 5+2}{2})

Mid\ points = (\frac{5}{2} , \frac{7}{2}).

Therefore, D).Mid\ points = (\frac{5}{2} , \frac{7}{2}).

BaLLatris [955]

Answer:

The maximum size of the smaller jars is 6 liters

Step-by-step explanation:

Container 1=174 liters of oil

Container 2=258 liters of oil

Same pours the entire content of container one and container 2 into the same number of smaller jars

The maximum size of the smaller jar can be found by finding the highest common factor of 174 and 258

Factors of 174=1,2,3,6,29

Factors of 258=1,2,3,6,43

Common factors of 174 and 258=1,2,3 and 6

Highest common factor=6

Therefore,

The maximum size of the smaller jars is 6 liters

Solve picture question. Mathematics.

Cross multiplication!
\frac{7}{8} = \frac{x}{24}
7 × 24 = 8x
168 = 8x

Divide both sides by 8 to isolate x

\frac{168}{8} = \frac{8x}{8}
8 and 8 cancels out

21 = x
