Answer:

Step-by-step explanation:

6) In rectangle, diagonals are equal.

KM = LN

6x + 16 = 49

6x = 49 - 16

6x = 33

x = 33/6

x = 5.5

7) 2x + 4 = 5x - 11

2x - 5x = -11 -4

-3x = -15

x = -15/-3

x = 5

In rhombus,diagonals make two congruent triangles

So, ∠ACD = ∠ACB

8) In Rectangle, diagonals are equal and bisect each other

x + 10 = 3x - 18

x - 3x = -18 -10

-2x = -28

x = -28/-2

x = 14

9) a + 36 = 180 { sum of co interior angles is 180}

a = 180 - 36 = 144

a = 144

113 + b = 180 { sum of co interior angles is 180}

b = 180 - 113

b = 67

What is the midpoint of the line segment with endpoints (-2, -2) and (4,6)?

IRINA_888 [86]

Answer:

(1,2)

Step-by-step explanation:

To find the midpoint, add the x coordinates and divide by 2

(-2+4)/2 = 2/2 =1

add the y coordinates and divide by 2

(-2+6)/2 = 4/2 = 2

The midpoint is

(1,2)

Find the coordinates of the other endpoint of the<br> midpoint (-6,23), endpoint (-4.19)

choli [55]

Answer:

(-8 , 27)

Step-by-step explanation:

$(-6,23)= (x ,y )\\\\(-4 ,19)=(x_1,y_1)\\\\x = \frac{x_1+x_2}{2}\\ \\-6 = \frac{-4+x_2}{2}\\ \\-12 =-4+x_2\\\\-12+4 =x_2\\-8=x_2\\\\y = \frac{y_1+y_2}{2}\\ \\23 = \frac{19+y_2}{2} \\\\46 =19+y_2\\\\46-19=y_2\\27=y_2$

fran swims at a speed of 2.6mph in stillwater the river flows at a speed of 0.4mph how long will it take her to swim 4.4mi upstr

yawa3891 [41]

Her speed will be affected by the speed of the river therefore her speed upstream will be 2.6-0.4 mph and her speed downstream will be 2.6+0.4mph
Therefore upstream it will take 4.4/2.2=2 hours
And downstream it will take 4.4/3=1.47 hours (3sf)

Solve the problem.

dimulka [17.4K]

Answer:

For this problem we can use the following proportional rule:

$\frac{73 mi}{25 gal}= \frac{x}{75 gal}$

Where x represent the number of miles that we can travel with 75 gallons. For this case we can use this proportional rule since by definition $D=vt$ . If we solve for x we got:

$x =75 gal (\frac{73 mi}{25 gal}) =219mi$

And the best answer would be:

219 mi
