Answer:

Points A, B, and Cform a triangle. Complete the statements to prove that the sum of the interior angles of AABC is 180°.

Statement

Reason

Points A, B, and C form a triangle.

given

Let DE be a line passing through B and parallel to AC. definition of parallel lines

23 – 25 and 21 - 24

m21 = m 24 and 23 = m25

m24+ m2 2 + 25 = 180°

mZ1 + Z2 + m23 = 180°

On a coordinate plane, a line goes through (negative 3, 2) and (0, 1). A point is at (3, 4). What is the equation of the line th

Novay_Z [31]

Answer:

$y=3x-5$

Step-by-step explanation:

step 1

Find the slope of the given line

we have

(-3,2) and (0,1)

The slope m is

$m=(1-2)/(0+3)=-1/3$

step 2

Find the slope of the line perpendicular to the given line

Remember that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of its slopes is -1)

The slope is

$m=3$

step 3

Find the equation of the line in point slope form

we have

$m=3$

$point(3,4)$

$y-4=3(x-3)$ ----> equation in point slope form

Convert to slope intercept form

$y=3x-9+4$

$y=3x-5$

3/10 divided by -1/3

Snezhnost [94]

Answer:

-9/10

Step-by-step explanation:

Find the LCM of 10 and 3: 30
Alter the numerators to fit the denominators: 3 × 3 = 9, -1 × 10 = -10
Re-write the fractions: 9/30 ÷ -10/30
9/30 ÷ -10/30 = 9/30 × -30/10
9/30 × -30/10 = -270/300
$-\frac{270}{300} = -\frac{9}{10}$

I hope this helps!

miskamm [114]

The fish box is 6 * 6 * 4 = 144 cubic square inches

144 = one box so divide 3456 by 144 to see how many boxes will go into the aquarium

3456 / 144 = 24
24 boxes of fish food could fit in the aquarium
