Answer: Rhombus
=====================================================
Explanation:
The tickmarks show that all four sides are the same length. Therefore, this figure is a rhombus. It is not a square because the angle would need to be 90 degrees. We can say it is a non-square rhombus, or a rhombus that isn't a square. It is also not a rectangle either because all rectangles have each angle at 90 degrees.
sum of the series:
13, 16, 19, ..., 301
how many numbers are in this series?
Answer:
97
Step-by-step explanation:
13,16,19,...,301
a=13
d=16-13=3
l=a+(n-1)d
301=13+(n-1)3
301-13=(n-1)3
(n-1)3=288
n-1=288/3=96
n=96+1=97

Is this correct
16-2t=5t+9
Answer: yes it is t={1}
PREMISES
16–2t=5t+9
CALCULATIONS
16–2t=5t+9
(16–9)-(2t-2t)=5t+2t+(9–9)
7–0=7t+0
7t=7
7t/7=7/7
t=1/1
t=
1
PROOF
If t=1, then the equations
16–2t=5t+9
16–2(1)=5(1)+9
16–2=5+9 and

Algebra
Domain is the set of x-values that can be inputted into function f(x)Step-by-step explanation:
According to the graph, we see that our x-values span from -4 to 4. Since both are closed dots, they are inclusive in the domain:
[-4, -4] or -4 ≤ x ≤ 4
Please find the domain and range!
Answer:
Domain: {-2, -3, 6, 8, 10}
Range: {-5, 1, 7, 9}
Step-by-step explanation:
Given:
{(6, -5), (-2, 9), (-3, 1), (10, 7), (8, 9)}
✔️Domain:
This includes all the set of the x-values that are in the relation. This includes, 6, -2, -3, 10, and 8.
Thus, the domain can be represented as:
{-2, -3, 6, 8, 10}
✔️Range:
This includes all corresponding y-values in the relation. They are, -5, 1, 7, and 9.
Range can be represented as:

A small company has one color printer and one black-and-white printer, each printing at different rates. The color printer, working for 5 minutes and the black-and-white printer working, working for 3 minutes, print a total of 70 pages. When the black-and-white printer works for 6 minutes and the color printer works for 9 minutes, they print a total of 135 pages. This is modeled by the situation below, where b is the number of pages per minute of the black-and-white printer and c is the number of pages per minute of the color printer 3b + 5c = 70 and 6b + 9c = 135 How many pages per minute does the black-and white printer print?
Answer:
The black-and white printer print can print 15 pages per minute.
Step-by-step explanation:
The given modeled equations are
3b + 5c = 70...(i)
6b + 9c = 135...(ii)
where b is the number of pages per minute of the black-and-white printer and c is the number of pages per minute of the color printer.
From equation (i), we have
[tex]3b=70-5c \\\\\Rightarrow b = \frac {70-5c}{3} \cdots(iii)[/tex]
Now, substitute the value of b in equation (ii), we have
[tex]6\times \frac {70-5c}{3}+9c=135 \\\\\Rightarrow 2(70-5c)+9c=135 \\\\\Rightarrow 140 - 10c+9c=135 \\\\\Rightarrow -c=135-140=-5 \\\\\Rightarrow c=5x^{2}[/tex]
By using equation (iii), we have
[tex]b = \frac {70-5\times5}{3}=\frac{45}{3}=15[/tex]
Hence, the black-and white printer print can print 15 pages per minute.
The black-and-white printer can print 15 pages per minute.
Given equations:
[tex]3b+5c=70[/tex] ........(i)
[tex]6b+9c=135[/tex] ........(ii)
Where b is the number of pages per minute of the black-and-white printer and c is the number of pages per minute of the color printer.
Solve the system of equations by substitution method
From (ii)
[tex]6b=135-9c\\b=\frac{135-9c}{6}[/tex] ........(iii)
Put the value of b in (i), we get
[tex]3(\frac{135-9c}{6} )+5c=70\\\frac{135-9c}{2} +5c=70\\135-9c+10c=140\\c=5[/tex]
put c = 5 in (iii)
[tex]b=\frac{135-9(5)}{6} =\frac{90}{6} =15[/tex]
Therefore, The black-and-white printer can print 15 pages per minute.

First of all, try to understand the questions then try to make a pair of linear equations. After that make the coefficients of x or y equal in both RFD equations by multiplying them by suitable values then add or subtract them ,in such a way which will terminate any one of the variables. Then find the value of left variable. After that just put the value you have found just now In any of the equations and you'll really get the value of the second variable too.
Jacqueline spent 33.50 to rent a bicycle. The bike rental facility charged $4 per hour and a processing fee of $1.50. For how many hours, x , did jacqueline rent the bicycle
Answer:
8 hours
Step-by-step explanation:
Given that:
Money spent by Jacqueline to rent a bicycle = $33.50
Per hour charges for the bicycle for renting the bicycle = $4
Processing fee charged for renting the bicycle = $1.50
To find:
The number of hours, [tex]x[/tex] for which Jacqueline rented the bicycle.
Solution:
Charges for 1 hour = $4
Charges for [tex]x[/tex] hours = $[tex]4x[/tex]
Processing fee = $1.50
Total fee charged for renting the bicycle is nothing but the sum of processing fee and the charges for [tex]x[/tex] hours charged by the bike rental facility.
Total money spent = Processing Fee + Charges for [tex]x[/tex] hours
Total money spent = 1.50 + 4[tex]x[/tex] = 33.50
[tex]\Rightarrow 4x = 32\\\Rightarrow x = \bold{8\ hours}[/tex]
So, Jacqueline rented the bicycle for 8 hours.

X^2+4x+20=12x-5
Solve this equation
Answer:
4 + (or -) 3i
Step-by-step explanation:
Hi!
Alright, so we're going to move all of the variables and constants to one side. Then, using the quadratic formula, we'll find the answer.
1. Move 12x-5 to the left side of the equation by
a. Subtracting 12x from both sides
b. adding 5 to both sides.
1: x^2+4x+20-12x+5
2. Group the common terms
x^2+4x-12x+20+5 --> x^2-8x+25
3. Look at the problem. We can't factor this.
Explanation for why this isn't factorable (you can skip this)
(1) 25 is positive, so its two factors will both be either positive or negative. We're looking for a negative 8, so let's go with negative.
(2) Factors of 25: 1 & 25, 5 &5
Seeing the problem? Ya, none of the factors of 25 sum to eight. So, instead, we're going to use the quadratic formula.
4. So, the quadratic formula: [tex]\frac{-b+-\sqrt{b^2-4ac} }{2a}[/tex]
Our equation is x^2-8x+25=0
a is the constant in front of the x^2
b is the constant in front of the x
c is the term without any x values
so, a=1, b=-8, and c= 25
Into equation:
[tex]\frac{8+-\sqrt{64-4(1)(25)} }{2a}[/tex]=[tex]\frac{8+-\sqrt{64-100} }{2}[/tex]=[tex]\frac{8+-\sqrt{-36} }{2}[/tex]
8/2 = 4
sqrt(-36) = 6i
6i/2 = 3i (remember, we still have the two in the denominator)
4 + (or -) 3i
Answer:
[tex]x=4+ 3\mathbf{i}[/tex]
[tex]x=4- 3\mathbf{i}[/tex]
Step-by-step explanation:
Solve:
[tex]x^2+4x+20=12x-5[/tex]
Move everything to the left side:
[tex]x^2+4x+20-12x+5=0[/tex]
Simplify:
[tex]x^2-8x+25=0[/tex]
Apply the solver formula:
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
Where a=1, b=-8, c=25. Thus:
[tex]\displaystyle x=\frac{8\pm \sqrt{(-8)^2-4(1)(25)}}{2*1}[/tex]
[tex]\displaystyle x=\frac{8\pm \sqrt{64-100}}{2}[/tex]
[tex]\displaystyle x=\frac{8\pm \sqrt{-36}}{2}[/tex]
The solutions are complex numbers:
[tex]\displaystyle x=\frac{8\pm 6\mathbf{i}}{2}[/tex]
Simplifying:
[tex]x=4\pm 3\mathbf{i}[/tex]
Two solutions are found:
[tex]x=4+ 3\mathbf{i}[/tex]
[tex]x=4- 3\mathbf{i}[/tex]

Would you rather go with the deal : 25% off of the $40 for christmas wrapping paper or the deal for 50% off of the $62 for christmas wrapping
Answer:
50% off of the $62 for christmas wrapping is the better deal
Step-by-step explanation:
Let us compare the prices after the discount
25% off of the $40 for christmas wrapping paper
=25/100*40
=0.25*40
=$10
The new price is
40-10=$30
50% off of the $62 for christmas wrapping
50/100*62
0.5*62
=$31
The new price is

there are 3,681 students at west school. Three grades attend this school. There are the same number of students in each grade. How many students are in each grade.
Answer:
1,227
Step-by-step explanation:
3,000 divided by 3 is 1,000
600 divided by 3 is 200
80 divided by 3 is 26 r2
1 + r2 =3
and 3 divided by 3 is 1
1,000 + 200 + 26 + 1 = 1,227

A telephone company offers two different types of billing. The first choice is to pay $10.00 per month plus $0.09 per MB of data. The second choice is to pay $16.00 per month plus $0.07 per MB of data.
How many MB of data would you have to use in one month in order for both plans to cost the same amount? Explain how you determined your answer.
Answer:
0.09x +10 is the first choice
0.07x +16 is the second choice (set the two data plans equal to each other)
0.09x +10 = 0.07x +16 (subtract 0.07x from both sides)
0.02x +10 = 16 (subtract 10 from both sides)
0.02x = 6 (divide both sides b 0.02 to isolate x)
x= 300 MB of data (the answer)
