Step-by-step explanation:
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
So number of rolls would equal:
7
Answer:
Step-by-step explanation:
7 rolls

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

Andrei's grandfather offered to give a gift of 50% of the amount of money he saved in one year. Andrei saved $120 dollars. How much did his grandfather give him as a gift? Mitch chose $180 as the correct answer. How did he get that answer?
Answer:
Mitch divided 120 by 2 to get 60. Then he added 60 to 120 to get 180.
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.

Brandon and Marta are mowing a lawn. for every 4 square feet that Brandon Mow's, Marta mow's 9 square feet. the lawn is 5200 square feet. how much lawn does each person mow?
Answer: 1600 square feet (Brandon)
3600 square feet (Marta)
Step-by-step explanation:
4:9
4+9 =13
5200/13 = 400
400 x 4 = 1600
400 x 9 = 3600
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?
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]
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
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.
