What's the value of x?
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.
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.
For each material listed in the table, find the mass for 1,000 cm3 in grams and kilograms. Then find the weight in pounds. Which material is the densest and which is the least dense? Why do you think this is true?

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.
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.

Write −1.111… as a mixed number in simplest form.
Answer:
-1 ¹/₉
Step-by-step explanation:
Firstly, let:
x = -1.111...
This means:
10x = -11.111...
Then:
10x - x = -11.111... - (-1.111...)
9x = -11.111... + 1.111...
9x = -10
x = -¹⁰/₉
x = -(⁹/₉ + ¹/₉)
x = -1 ¹/₉
solve this for me, please

Only numbers greater than 5 satisfy the inequality.
The answer is a set that only contains numbers greater than 5.
Answer: {6, 8, 10}
The values that satisfies the condition n+5>10 among {2,4,6,8,10} is
{6,8,10}
let check the every value of {2,4,6,8,10} satisfies the condition n+5>10
let n=2
= n+5 = 2+5 = 7
7!>10
so 2 does not satisfies the condition
let n=4
= 4+5 = 9
9!>10
lly 4 does not satisfies the condition
let n= 6
=n+5 = 6+5 = 11
11>10 satisfies the condition
let n= 8
=n+5 = 8+5 = 13
13>10 satisfies the condition
let n= 10
=n+5 = 10+5 = 15
15>10 satisfies the condition
only {6,8,10} satisfies the given condition

400 x 9 = 3600
What's the answer to b = and c =
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
As a nurse, part of your daily duties is to mix medications in the proper proportions for your patients. For one of your regular patients, you always mix Medication A with Medication B in the same proportion. Last week, your patient's doctor indicated that you should mix 120 milligrams of Medication A with 132 milligrams of Medication B. However this week, the doctor said to only use 121 milligrams of Medication B. How many milligrams of Medication A should be mixed this week?

Let x be each roll of blue tickets the student council orders. They ordered 1 roll of 150 golden tickets, and plan to order blue tickets that come in rolls of 200. They plan to order a total number of, 1550 tickets..
The equation to represent this will be,
150 + 200x = 1550
We need to solve for X =
200x = 1400 =
x = 7
