AB is parallel to CD. Find the measure of each numbered angle.

Answers

Answer:

#4 angle 1 = 154 degrees

#4 angle 2 = 26 degrees

#5 angle 1 = 97 degrees

#5 angle 2 = 82 degrees

#5 angle 3 = 83 degrees

Step-by-step explanation:

The image displays which angles are the same on line equations like these using color coding.

In order to translate between the green angle and the pink angle you subtract it from 180.

Equation: 180 - angle type 1 = angle type 2

Ex: 180 - 154 = 26

a recipe calls for 5/8 cup of sugar for every 5 teaspoons of vanilla. what is the unit rate in cups per teaspoon?

a) 3 1/8
b) 1/8
c) 8
d) 8/25

Answers

Answer:

b) 1/8

Step-by-step explanation:

5/8 ÷ 5 = 1/8

The unit rate in cups per teaspoon is 1/8 cup of sugar.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

5/8 cup of sugar=5 teaspoons of vanilla.

or, 5 teaspoons of vanilla = 5/8 cup of sugar

So, 1  teaspoon of vanilla = (5/8)/5 cup of sugar

(5/8)/5 = (5/8)*(1/5)

(5/8)/5 =1/8

So, 1 teaspoon of vanilla = 1/8 cup of sugar

Hence, the unit rate in cups per teaspoon is 1/8 cup of sugar.

can you use the term parallelogram to describe a rectangle

Answers

Answer:

Yes. In order for a shape to be qualified as a parallelogram It has to have 4 main properties. Opposite sides are parallel. Opposite sides have to be congruent. The opposite angles are congruent. Consecutive angles are supplementary (adds to 180-degrees). A rectangle qualifies all of these properties for a parallelogram. Opposite sides are parallel which works for a rectangle since they never intersects with the oppposit line. Opposite sides are congruent or equal which is also true becuase when looking at any 2 opposite sides of a rectangle, its always gonna be equal. Opposite angles are congurent which is also true because their all 90 degrees all are equal. And finally consecutive angles add up to 180. Soncsuive int his case basically means the angle next to that angle but we don’t have to worry about that since all angles of a rectangle are 90 and 90+90=180 so it also DOES qualify for a parallelogram.

Anna said that the product of 78⋅112=7278·112=72.


How can you tell that her answer is wrong?

Answers

Answer:

The easiest way I can think of to show someone who is not very mathematically inclined that the calculation is wrong (other than using a scientific calculator) is this:

Explain that one half contains four eighths - you can visualize this very simply with a pie chart.

Then tell Anna that mathematically speaking this translates to the equation:

1/2 = 4 * 1/8

Now, if ONE half is equal to four times ONE eighths, then SEVEN halves is equal to four times SEVEN eighths - basically, you just multiply both sides by 7:

7/2 = 4 * 7/8

Now, compare this to the equation proposed by Anna:

7/2 = 1½ * 7/8

I guess, at this point it will be easy to convince Anna that 1½ is not 4, and therefore her equation is faulty.

-----

Alternatively, if she's sound with fractions you could also tell her that to get from 7/8 to 7/2 you will need a factor which only affects the denominator as the numerator stay the same. The factor that turns 8 into 2 is 1/4 but since this takes place in the denominator we need the reciprocal to turn 1/8 into 1/2 - and the reciprocal of 1/4 is of course 4. At which point we've arrived at the same place of argumentation as before (which is that 4 ≠ 1½).
