Answer:

1)  \sqrt{106}

2) \sqrt{187

3) x=30

4) x= -4/3

Step-by-step explanation:

Use the Pythagorean theorem to find the missing angle.

In the formula, the c is the length of hypotenuse, so

c=\sqrt{9^2+5^2} \\c=\sqrt{106}

3^2+b^2=14^2\\b^2=196-9\\b=\sqrt{187}

20*9=6x

180=6x

x=30

4(3x+2)=6x

12x+8=6x

6x=-8

x= -4/3

In the diagram below DE is the midsegment of AABC.<br> Find the length of DE and BC.
baherus [9]

Answer:

DE = 5

BC = 10

Step-by-step explanation:

ΔAED is a right triangle with legs of 4 and 6/2 = 3

Use the Pythagorean theorem to find DE

4^{2}  + 3^{2} = DE^{2}

16 + 6 = 25 = DE^{2}

DE = 5

The midsegment of a triangle is 1/2 the length of the corresponding side.

Therefore, BC = 2 DE = 2(5) = 10 = BC

Find an equation of the line that contains the point (-1,3) and is parallel to the line x+3y=6.
Bas_tet [7]

Answer:

Step-by-step explanation:

3y = -x + 6

y = -1/3x + 2

y - 3 = -1/3(x + 1)

y - 3 = -1/3x - 1/3

y - 9/3 = -1/3x - 1/3

y = -1/3x + 8/3

Answer:

960 ounces in 1 day

(Sorry for a late response, I just logged on)

Step-by-step explanation:

Most of that information is negligable (not important) besides 8 ounces in 12 minutes.

so an hour is 60 minutes, if we multiply both parts of the problem by 5 we get

40 ounces in 1 hour

a day is 24 hours, so if we multiply both sides by 24 well get our answer

960 ounces a day
