D.62.8 cm, because C = 207
Answer:
The answer is D. 62.8
Step-by-step explanation:
I used this formula.
Circumference = 2πr
GEOMETRY Holly can make an open-topped box out of a square piece of cardboard by cutting 3-inch squares from the corners and folding up the sides to meet. The volume of the resulting box is V = 3x^ 2 – 36x + 108, where x is the original length and width of the cardboard.
Factor the polynomial expression from the volume equation.
HINT: look for a GCF first!
Answer:
[tex]V(x)=3(x-6)(x-6)[/tex]
Step-by-step explanation:
Polynomial Factoring
The volume of a cardboard box is expressed as:
[tex]V(x)=3x^2-36x+108[/tex]
It's required to factor that expression.
First, factor out 3:
[tex]V(x)=3(x^2-12x+36)[/tex]
The expression in parentheses is a perfect square:
[tex]\boxed{V(x)=3(x-6)(x-6)}[/tex]

Solve the simultaneous equations by substitution
8x – 3y = 5
3y = 2x + 1
Answer:
x = 1
y = 1
Step-by-step explanation:
this should be your answer
Answer:
(1, 1 )
Step-by-step explanation:
Given the 2 equations
8x - 3y = 5 → (1)
3y = 2x + 1 → (2)
Substitute y = 2x + 1 into (1)
8x - (2x + 1) = 5
8x - 2x - 1 = 5
6x - 1 = 5 ( add 1 to both sides )
6x = 6 ( divide both sides by 6 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for y
Substituting into (2)
3y = 2(1) + 1 = 2 + 1 = 3 ( divide both sides by 3 )
y = 1
solution is (1, 1 )

lf p+q/s=9, q/p =4, and square q=6, what is the value of s?
Answer:
s=5
Step-by-step explanation:
The third equation implies that q=36.
Substitute for q in the second equation to get
36/p=4
Now solve for p
p/36=1/4
p=36/4=9
Solve the first equation for s.
s/(p+q)=1/9
s=(p+q)/9
Now substitute for q and p in this equation.
s=(9+36)/9=45/9=5

If 8x - 5y = -8 is a true equation, what would be the value of -5y + 8x?
Answer:
Answer:
The value of -5y + 8x would be 8.
Step-by-step explanation:
The new equation is just the original equation but multiplied by -1 to make the symbols different. By following this rule, -8 would turn into just 8.

Lin's sister has a checking account. If the account balance ever falls below zero, the bank charges her a fee of $5.95 per day. Today, the balance in Lin's sister's account is -$2.67. In 14 days, Lin's sister will be paid $430 and will deposit it into her checking account. If there are no other transactions besides this deposit and the daily fee, will Lin continue to be charged $5.95 each day after this deposit is made? Explain or show your reasoning.
Answer: No, the bank will not keep charging her the $5.95 after the deposit is made.
Step-by-step explanation:
Today, Lin's sister's balance is -$2.67
She gets charged $5.95 per day.
There are 14 days until she can charge some money in the bank account, so the bank will charge $5.92 14 times
So her balance after 14 days will be:
Balance = -$2.67 - $5.95*14 = -$85.97
When she charges the $430 in the account, her balance will be:
Balance = -$85.97 + $430 = $344.03
So now she has a positive balance, which means that the bank does not charge her anymore.
what is the amount of pieces in each color
Answer:
brown = 12
yellow = 30
orange = 36
Step-by-step explanation:
let 'b' = # brown
let '18+b' = # yellow
let '3b' = #orange
add them together and set equal to 78
b + 18 + b + 3b = 78
5b + 18 = 78
5b = 60
b = 12
y = 12 + 18 = 30
o = 3(12) = 36
12 + 30 + 36 = 78

Neelam's daily income is ₹ 800. Her daily savings amount is ₹100. What is the ratio of her SAVINGS to her EXPENDITURE? a. 1 : 2 b. 1 : 7 c. 1 : 6 d. 1 : 5
Given:
Neelam's daily income is ₹800.
Her daily savings amount is ₹100.
To find:
The ratio of her SAVINGS to her EXPENDITURE.
Solution:
We have,
Income = ₹800
Saving = ₹100
Expenditure = Income - Saving
= ₹800 - ₹100
= ₹700
We need to find the ratio of her SAVINGS to her EXPENDITURE.
[tex]Ratio=\dfrac{Savings}{Expenditure}[/tex]
[tex]Ratio=\dfrac{100}{700}[/tex]
[tex]Ratio=\dfrac{1}{7}[/tex]
[tex]Ratio=1:7[/tex]
Therefore, the correct option is b.

Find the 6th term 9 18 36
Answer:
I think the answer is 288.
Step-by-step explanation:
The rule seems to be multiplying the past number by 2. So, 9*2=18 and 18*2=36. If we continued that rule we would then get 72, 144, and the sixth term is then 288.
hope this helps :D
Answer:
Step-by-step explanation:
This is a geometric sequence because any term divided by the previous term is a constant called the common ratio. r=36/18=18/9=2 A geometric sequence is expressed as
[tex]a_n=ar^{n-1},\text{ where a=initial term, r=common ratio, n=term number}\\ \\ a_n=9(2^{n-1})\\ \\ a_6=9(2^5)\\ \\ a_6=288[/tex]
