If M ⊥ N and L ∥ M, then _____

joja [24]

Answer:

L ⊥ N

Step-by-step explanation:

Since M and N are perpendicular, and L is parallel to M, anything that's perpendicular to M is also perpendicular to L. In fact, since we have parallel lines, we now have many sets of congruent angles, but the only ones we know the actual measurements of are the right angles from the perpendicular lines.

U.S. Customary unit conversion with mixed number values: One... A cook needs 7 cups of vegetable stock for a soup recipe. How mu

lapo4ka [179]

The pints of vegetable stock the chef needs is $3\frac{1}{2}$ .

<h3>How many pints does he need?</h3>

The first step is to determine the unit of conversion of cups to pints.

1 cup = 0.5 pints

To convert cup to pints, multiply 7 by 0.7

7 x 0.5 = 7/2 = $3\frac{1}{2}$

What does this mean: 70°20'

timurjin [86]

70 degrees, 20 minutes. It's an angle measure in Degrees-Minutes-Seconds(DMS) instead of Decimal Degrees (DDS). DMS is commonly used in engineering, land survey and navigation for ships and planes.

There are 60 seconds in one minute and 60 minutes in one degree.
So 70°20' is = $70\frac{20}{60}deg \approx70.33deg$

Solve by substitution x-y=-11 y+7=-2x

Bess [88]

x - y = - 11 .............( 1 )

y + 7 = - 2x ...............( 2 )

from equation ( 1 )

x - y = - 11

x = -11 + y ...........( 3)

putting x in equation ( 2 )

y + 7 = - 2 x

y + 7 = -2 ( -11 + y ) y + 7 = 22 - 2 y y + 2 y =22 - 7

3 y = 15 y = 15 / 3

putting value of y in equation 3

x = -11+ ( 13 /5 ) x = -33 /3 + 15 / 3 ( l.c.m)

x = -17 / 5

check

x = -11 + y

- 17 / 5 = -11 + 13 / 5

-17 /5 = -17 / 5
