Determine the midpoint given 2<br> points.<br> (6,-10), (10,7)?

NISA [10]

Hey there! I'm happy to help!

To find the x-value of the midpoint, you add the x values and divide by 2.

6+10=16

16/2=8

And for the y value, you do the same thing but with the y values.

-10+7=-3

-3/2=-3/2

Therefore, our midpoint is (8,-3/2).

Have a wonderful day! :D

What is the largest flag jake can draw

alexgriva [62]

The ratio of length to width is 3/2. Let's set up equations of ratios using first the 25 cm length of the paper and then the 20 cm width:

3 25 cm
--- = ----------
2 x

Solving for x, 3x = 50 cm, and x =16 2/3 cm. This is possible, since 16 2/3 is less than the paper width 20 cm.

3 20 cm
--- = -----------
2 x

Solving for x: 3x = 40 cm; x = 40/3 cm, or x= 13 1/3 cm. This is possible, but does not make maximum use of the 20 by 30 cm paper.

Answer: the largest flag Jake can draw on the paper given is 20 cm (length) by 16 2/3 cm.

I need the answer to this please help

Brums [2.3K]

Answer:

-1/11

Step-by-step explanation:

$\frac{11x}{12} -\frac{1}{6} =\frac{-1}{4}$ add 1/6 to both sides

$\frac{11x}{12} =\frac{1}{6} -\frac{1}{4}$ make the same denominator 12 on the right side

$\frac{11x}{12} =\frac{1}{6}*\frac{2}{2} -\frac{1}{4}*\frac{3}{3}$ solve

$\frac{11x}{12} =\frac{2}{12} -\frac{3}{12} =\frac{2-3}{12} = \frac{-1}{12}$

$\frac{11x}{12}*12 =\frac{-1}{12} *12$ multiply by 12 both sides

11x= -1 divide by 11

x= -1/11

Take a look at the picture below and follow the rules using the STRATEGY, you need to draw the strategy to get the answer. brain

Aliun [14]

I would say (I am abbreviating square root to sqrt)

1. 4 sqrt(8488) = 4 sqrt(2x2x2122) = 8 sqrt(2122)

2. 3 sqrt(6936) = 3 sqrt(6x34x34) = 102 sqrt (6)

3. 2 sqrt(8648) = 2 sqrt(2x2x2162) = 4 sqrt(2162)

The gas tank is 20% full. At $3.00 per gallon of gas, find the cost to fill the tank. (1 gal = 231 in.3)

rewona [7]

The correct question in the attached figure

we know that

to fill the tank is required--------> 100%-20%--------> 80%
if 20% of the gas tank is-----------------> 288.75 gal
80% --------------------------------------> X gal
X=80*288.75/20--------> X=1155 gal

if 1 gal----------------> cost $3
1155 gal----------> $X
X=1155*3--------> X=$3465

the answer is
the cost to fill the tank is $3465
