Step-by-step explanation:

5) Corresponding angles are angles that are on the same side of one of two cut lines by a transversal.

Therefore, the corresponding angles are (A,C) and (B,D).

6) Alternate exterior angles are angles which that are on opposite sides of a transversal, but are also equal.

Therefore, the alternate exterior angles are (D,C) and (A,H).

Answer:

5. A, C B, D E, G F, H

6. B, G F, C

Step-by-step explanation:

When two lines are cut by a transversal, corresponding angles are on the same side of the transversal and are both on the same side of the two lines.

Pairs of corresponding angles:

A, C B, D E, G F, H

When two lines are cut by a transversal, alternate interior angles are a pair of angles that are both inside the two lines, are on different sides of the transversal, and are not adjacent.

Pairs of alternate interior angles:

B, G F, C

Theodore needs to mix a 30% alcohol solution with a 50% alcohol solution to create 100 milliliters of a 32% solution. How many m

Goryan [66]

Answer:

50 % alcohol solution = 10 millimetres

30 % alcohol solution = 90 millimetres

Step-by-step explanation:

two equations can be derived from this question

x + y = 100 equation 1

0.3x + 0.5y = 100 x 0.32 = 32

0.3x + 0.5y = 32 equation 2

where :

x = 30% alcohol solution

y = 50% alcohol solution

multiply equation 1 by 0.3

0.3x + 0.3y = 30 equation 3

subtract equation 3 from 2

0.2y = 2

y = 10

substitute for y in equation 1

x + 10 = 100

x = 100 - 10

x = 90

What ks the % of 4 = 2

Fittoniya [83]

Answer:

$50\%$

Step-by-step explanation:

Let x be the percentage then...

$x\%(4)=2$

Start by dividing both sides by 4:

$x\%=\frac{2}{4}$

Simplify the fraction:

$x\%=\frac{1}{2}$

Then, multiply the fraction by 50/50, so we can get a number over 100 (that number would be the percentage). Note we can only multiply it by 50/50 since it is essentially multiplying the fraction by 1.

$x\%=\frac{1}{2}*\frac{50}{50}\\x\%=\frac{50}{100}\\x=50\%$
