What's the answer to b = and c =

Answers

Answer:
b = 21°
c = 159°

Step-by-step explanation:

To solve for B we have to know that the opposite angle is the same. So 21° is the same as angle b.

To solve for C we have to know that a line adds up to 180°. So 21° plus c = 180

To find this we do 180 - 21 = 159.

I hope this helps you :D

Answer:

B = 21

C = 159

Step-by-step explanation:

As we are given 21 degrees as one of the angles, we can also notice that both lines are straight, so they are both adding up to an angle of 180 each.

To find C, we can use this equation:

C + 21 = 180

C = 180-21

C = 159

To find B, we can use this equation:

B + C = 180

Plug in C:

B + 159 = 180

B = 180-159

B = 21

A company has recently been hiring new employees. Today the company has 32% more employees than it did a year ago. If there are currently 29,700 employees, how many employees did the company have a year ago?

Answers

the company a  year ago had "x" employees, which oddly enough is the 100%.

now, today they have 32% more  than that, well, 100% + 32% = 132%, and we know that's 29,700 employees

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x & 100\\ 29700& 132 \end{array} \implies \cfrac{x}{29700}~~=~~\cfrac{100}{132} \\\\\\ \cfrac{ x }{ 29700 } ~~=~~ \cfrac{ 25 }{ 33 }\implies 33x=742500\implies x=\cfrac{742500}{33}\implies x=22500[/tex]

Answers

Answer:

x = 62

Step-by-step explanation:

Recall the properties of parallel lines with transversals. Vertical angles are congruent so the angle across from 118° is also 118°.

Recall the consecutive interior angles theorem. If two angles are on the same side of the transversal and are between the two parallel lines, then their measures add up to 180°. 180° - 118° = 62°.

Therefore, x = 62.

Figure ABCD is shown on the coordinate plane. Suppose a graphic designer wants to dilate the figure so that the resulting image has a smaller area than figure ABCD. Describe a way the designer can achieve this type of dilation.

Answers

Answer:

Step-by-step explanation:

If the dilated image is smaller than the original, then 0<k<1.

Meaning the scale factor is less than one, but greater than zero.

You would mulitply each coordinate by this scale factor - to obtain the coordinates of the dilated figure.

Let's choose   [tex]\frac{1}2}[/tex].

In the original figure Point A = (-4,3) dilating by [tex]\frac{1}{2}[/tex] results in A' being (-2, 1.5).  When you multiply each cooordinate (-4,3) by one half.

Applying the scale factor of one half to the other coordinates - yields these results.

Point B (4,3) becomes Point B' (2, 1.5)

Point C (-4,-4) becomes Point C' (-2,-2).

Point D (4, -4) becomes Point D' (2,-2)

Answer:

K will equal something more than 0 and less than 1.

Explanation:

Multiply each side length by the same factor, a number between 0 and 1.

The materials listed in the table below are called elements. They are substances that are found in nature. Some are metals, like aluminum, copper, iron, lead, silver, tin, and nickel. Some are gasses, such as hydrogen and oxygen.

We use all of these elements in everyday life. Pennies were originally copper, quarters were silver, and nickels were made of nickel. Most soda cans are aluminum. Water is made of hydrogen and oxygen, and we breathe oxygen. Salt is mostly made of sodium.

So, think about these materials and how heavy they would feel if you had a cubic centimeter of each one.
