What is the 50th term of the sequence that begins -6,0,6,12
a. 292
b. 288
c. 286
d. 290
Answer:
The 50th term of the sequence that begins with - 6 is 288.
Step-by-step explanation:
Definition of Arithmetic ProgressionAn arithmetic progression, also known as an arithmetic sequence, is a set of numbers in which the difference between successive terms remains constant. The sequence 5, 7, 9, 11, 13, 15,... is, for example, an arithmetic progression with a common difference of 2.
Formula -[tex]$a_{n}=a_{1}+(n-1) d$[/tex]
The given sequence is − 6, 0, 6, 12,It is in arithmetic progression as the common difference between all consecutive numbers is 6.
Let a1 be the first term and d be the common difference.
Therefore, a1 = - 6 and d = 6
For 50th term, a50 = a1 + (n - 1) d
= - 6 + (50 - 1) 6
= - 6 + 49 × 6
= - 6 + 294
= 288
Thus, the 50th term of the sequence is 288.

Round 958.989730738 to the nearest hundred.
Answer:
958.99
Step-by-step explanation:
Assuming you meant "hundredth", for the nearest hundredth term you would need to round up to the 2nd number behind the decimal. The thousandth digit of the number is 9, since 9 is greater than 4, you would need to round up by 1 to get 958.99.

Factor
X^2 + 6x + 9
Please show all work and use a factor tree
Answer:
Step-by-step explanation:
X^2 and 9 are two squares, while 6 can be obtain my multiplying x and 3 by 2.
so this is a square of a binomial
(x+3)^2
or
(x+3)(x+3)
Answer:
(x+3)², if looking for x, X = -3
Step-by-step explanation:
X²+6x+9 is a perfect square as you immediately can see that 3+3 = 6 and 3*3 = 9.
I used the generic rectangle to solve it, 9 into top right corner and then x² onto the bottom left, multiplying eachother to get 9x² which is formed by 3x and 3x multiplied so you would have (x+3) (x+3).

Find the distance between the two points rounding to the nearest tenth (if necessary)
(8,7) and (1,-2)
Answer:
≈ 11.4
Step-by-step explanation:
Calculate the distance using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (8, 7) and (x₂, y₂ ) = (1, - 2)
d = [tex]\sqrt{(1-8)^2+(-2-7)^2}[/tex]
= [tex]\sqrt{(-7)^2+(-9)^2}[/tex]

Which country would be the BEST trading partner for all three countries in the table?
A.
a country with a high demand for oil
B.
a country that specializes in producing oil
C.
a country with a high demand for automobiles
D.
a country that specializes in producing automobiles
Answer:a
Step-by-step explanation:
I’m pretty sure it’s A
The best trading partner for a country depends on complementary resources and needs, and a country that specializes in producing the goods that another country has a high demand for can be a good trading partner.
What is the trading partner?A trading partner is a nation or other organization with which another nation conducts trade, frequently through the exchange of products and services, in the context of international trade. Trading partners can be crucial for a nation's economy since they open up doors to new markets, boost exports, and create chances for expansion.
A good trading partner should have resources and needs that are compatible with those of other nations. A nation that excels in producing oil, for instance, would be a suitable trading partner for nations that have a strong need for oil but may not be able to supply it itself.
Similarly to this, a nation that specializes in manufacturing cars would make an excellent trading partner for nations that have a strong demand for cars but might not be able to create them on their own.
These findings suggest that choices A and C are less likely to be the greatest trading partners for all three countries since they only take into account the requirements of one or two of them.
A country in Option B, which specializes in oil production, might make an excellent trading partner for nations with significant oil demand.
Option D, a nation that specializes in manufacturing cars, might make an excellent trading partner for nations with a high demand for cars.
It is challenging to decide which choice would be the ideal trading partner for all three countries without more details about the unique needs and resources of the nations on the table.

I need to find the cube root of both of these equations. Thanks!
Answer:
3) -1
4) [tex]-\frac{2}{3}[/tex]
Step-by-step explanation:
Taking the cube root of a number is the same as finding what number times itsef three times equals the number under the radical sign.
[tex]\sqrt[3]{-1}[/tex]
[tex]=-1[/tex]
Since (-1) times itself, three times equals (-1).
[tex]\sqrt[3]{-\frac{8}{27}}[/tex]
[tex]=-\frac{2}{3}[/tex]
Since ([tex]-\frac{2}{3}[/tex]) times itself three times equals ([tex]-\frac{2}{3}[/tex]).
Helen made a scale drawing of an office building. A desk, which is 6 feet long in real life, is 2 inches long in the drawing. What scale did Helen use for the drawing
Answer:
1 inch = 3 feet
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
6 /2 = 3
1 in = 3 feet
Andrea used 4 1/3 yards of material to make a dress she has 1 1/4 yards left over how much material did Andrea start with
Answer:
[tex]1\frac{7}{12}\quad[/tex] yards [tex]\left(\mathrm{Decimal:\quad }\:1.58333\dots \right)[/tex]
Step-by-step explanation:
To find how much Andrea started with, subtraction is needed. To subtract, we need to set up fractions;
[tex]4\frac{1}{3}-\frac{11}{4}[/tex]
Convert the mixed number to an improper fraction: [tex]a\frac{b}{c} = \frac{a \cdot c+b }{c}[/tex][tex]4\frac{1}{3}=\frac{4\cdot 3+1}{3}[/tex]
[tex]=\frac{13}{3}[/tex]
[tex]=\frac{13}{3}-\frac{11}{4}[/tex]
Least common multiplier: 3,4 = 12
Adjust fractions based on the LCM
[tex]=\frac{52}{12}-\frac{33}{12}[/tex]
Apply the fraction rule: [tex]\quad \frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}[/tex]
[tex]\frac{52}{12}-\frac{33}{12}=\frac{52-33}{12}[/tex]
[tex]=\frac{52-33}{12}[/tex]
Add the numbers: [tex]52-33=19[/tex]
[tex]=\frac{19}{12}[/tex]
Convert the improper fraction to mixed numbers: [tex]Quotient \frac{Remainder}{Divisor}[/tex][tex]\frac{19}{12}=1\frac{7}{12}[/tex]
[tex]=1\frac{7}{12}[/tex]
Therefore, Andrea started with [tex]1\frac{7}{12}[/tex] yard material.
There are 3 boys for every 4 girls in a classroom. If there are 9 boys, how many girls are in the classroom?
PLEASE HELP!!
Answer:
36 girls in the class
Answer:
12 girls are in the classroom.
Step-by-step explanation:
We find out that the ratio is 3:4 based upon the question.
If there's 9 boys then the ratio is incomplete however you just need complete it based on the information given.
So, 3:4
9:?
9 / 3 = 3
4 x 3 - 12 girls
Thus, there being 12 girls in the classroom.
To check:
9:12;
9 / 3 = 3
12 / = 4
So the ratio still ends up being 3:4 therefore 9:12 is equivalent and correct!

What is the ft and in
Question is ;
Complete question is;
Boston , Massachusetts, and buffalo, New York, are hit by snowstorms that last 3 days . Boston accumulates snow at a rate of 1.5 feet every 36 hours. Buffalo accumulates snow at a rate of 0.01 inches every minute.
Which city accumulates more snow in 3 days? How much more snow?
Answer:
- Boston accumulates more snow in 3 days.
- It accumulates 0.6 ft of snow more than Boston
Step-by-step explanation:
Boston accumulates 1.5 feet of snow every 36 hours.
Number of hours in 3 days = 24 × 3 = 72 hours.
Thus, In 72 hours, Boston would have accumulated; (1.5 × 72)/36 = 3 feet of snow.
Now, Buffalo accumulates 0.01 inches of snow every minute.
In 3 days, number of minutes we have = 60 × 24 × 3 = 4320 minutes
Thus, total snow accumulated in 3 days = 0.01 × 4320/1 = 43.2 inches
Now, let's convert this to ft;
12 inches = 1ft
Thus; 43.2 inches = 43.2 × 1/12 = 3.6ft
Thus, Buffalo accumulates more snow in 3 days.
It accumulates 0.6 ft of snow more than Boston
