Jaxon must sell at least 49 rolls of wrapping paper to support the robotics club fundraiser. He has already sold 24 rolls of wrapping paper. Which inequality best represents the number of rolls of wrapping paper Jaxon still needs to sell
Answer:
x≥25
Step-by-step explanation:
Step one:
given data
Jaxon must sell at least 49 rolls of wrapping paper to support the robotics club fundraiser
We are told that he has already sold 24 rolls of wrapping paper.
Step two:
let x be the number of rolls remaining to be sold,
hence,
x≥49-24
x≥25
Therefore the inequality for the situation is x≥25
which reads that x must be greater than or equal to 25

3х – 10 = 16
Answer:
x=26/3
Step-by-step explanation:
3x-10=16
add 10 to both sides
3x=16+10
simplify
3x=26
divide both sides by 3
x=26/3

Given:
[tex]\cos^4 \alpha+\sin^4\alpha=\dfrac{1}{4}(3+\cos 4 \alpha)[/tex]
To prove:
The given statement.
Proof:
We have,
[tex]\cos^4 \alpha+\sin^4\alpha=\dfrac{1}{4}(3+\cos 4 \alpha)[/tex]
[tex]LHS=\cos^4 \alpha+\sin^4\alpha[/tex]
[tex]LHS=(\cos^2 \alpha)^2+(\sin^2 \alpha)^2[/tex]
[tex]LHS=(\cos^2 \alpha+\sin^2\alpha)^2-2\sin ^2\alpha\cos^2 \alpha[/tex] [tex][\because a^2+b^2=(a+b)^2-2ab][/tex]
[tex]LHS=(1)^2-2(1-\cos^2 \alpha)\cos^2 \alpha [/tex] [tex][\because \cos^2 \alpha+\sin^2\alpha=1][/tex]
[tex]LHS=1-2\cos^2 \alpha+2\cos^4 \alpha [/tex]
Now,
[tex]RHS=\dfrac{1}{4}(3+\cos 4 \alpha)[/tex]
[tex]RHS=\dfrac{1}{4}[3+(2\cos^2 2\alpha-1)][/tex] [tex][\because \cos 2\theta=2\cos^2\theta -1][/tex]
[tex]RHS=\dfrac{1}{4}[2+2\cos^2 2\alpha][/tex]
[tex]RHS=\dfrac{1}{4}[2+2(2\cos^2 \alpha-1)^2][/tex] [tex][\because \cos 2\theta=2\cos^2\theta -1][/tex]
[tex]RHS=\dfrac{1}{4}[2+2(4\cos^4 \alpha-4\cos \alpha+1)][/tex] [tex][\because (a-b)^2=a^2-2ab+b^2][/tex]
[tex]RHS=\dfrac{1}{4}[2+8\cos^4 \alpha-8\cos \alpha+2][/tex]
[tex]RHS=\dfrac{1}{4}[4+8\cos^4 \alpha-8\cos \alpha][/tex]
[tex]RHS=1+2\cos^4 \alpha-2\cos \alpha[/tex]
[tex]RHS=1-2\cos^2 \alpha+2\cos^4 \alpha [/tex]
[tex]LHS=RHS[/tex]
Hence proved.

B- y= -x-4
y= 2x-2
C- y= x+4
y= -2x-4
D- y= -x+4
y= 2x-4
Answer:
C
Step-by-step explanation:
First of all, we can see for both of the slopes, the Y intercept is both -4, and +4. Now that we know that information, we can go on to "mx" or the slope. now since we've narrowed down the answers, we have C and D left. Now in C, the x for "x+4" doesn't specifically say the value. Now for the equation below x+4 (for C) shows -2x-4, which does show the value of X, which is correct, because it shows in the graph that there's -2x. Now on D, they put the negative symbol on X, which doesn't say the value, but there's no negative in "2x-4" for 2x. and there's no slope that goes through positive 2. Therefore it would be C.

coral invested $500 in an account that earns simple interest at the rate of %5.5 each year. Assuming coral does not invest anymore money it will take how many years for coral to have %720 in her account?
Answer:
The number of years it will take coral to have $720 in her account is 8 years
Step-by-step explanation:
The principal amount coral invested, P = $500
The simple interest rate earned per year, r = 5.5%
The amount in coral account after t years, A = $720
The formula for simple interest is given as follows;
[tex]Simple \ Interest, \ SI = \dfrac{Principal, P \times Rate, r \times Time, t}{100}[/tex]
The formula for amount, A = SI + P
Therefore, we have;
[tex]A = \dfrac{P \times r \times t}{100} + P[/tex]
[tex]720 = \dfrac{500 \times 5.5 \times t}{100} + 500[/tex]
[tex]720 - 500 = \dfrac{500 \times 5.5 \times t}{100}[/tex]
[tex]220 = \dfrac{500 \times 5.5 \times t}{100}[/tex]
22000 = 500 × 5.5 × t
t = 22000/(500 × 5.5) = 8
The number of years, t, it will take coral to have $720 in her account = 8 years.
An online clothing company sells custom sweatshirts. The company charges $ for shipping plus $ for each sweatshirt. Write a linear function rule that models the total cost y (in dollars) for any number of sweatshirts x.
Complete question :
An online clothing company sells custom sweatshirts. The company charges $4.99 for shipping plus $7.50 for each sweatshirt. Write a linear function rule that models the total cost y (in dollars) for any number of sweatshirts x.
Answer:
y = 7.50x + 4.99
Step-by-step explanation:
Given that :
Shipping fee = 4.99
Cost per shirt = 7.50
Writing the relation in the form of a linear equation :
General form of a linear function :
y = mx + c
Where m = slope ; c = intercept
The total cost of ordering x sweatshirts :
y = (cost per sweatshirt * number ordered) + shipping fee
y = 7.50x + 4.99
Answer:
the answer is $7.99

Write an explicit formula that represents the sequence defined by the following recursive formula
HELP IM TIMED
Answer:
The explicit formula is a[tex]_{n}[/tex] = 5 - 6n
Step-by-step explanation:
The explicit formula of the arithmetic sequence of the recursive formula
a[tex]_{1}[/tex] = first term; a[tex]_{n}[/tex] = a[tex]_{n-1}[/tex] + d is a[tex]_{n}[/tex] = a + (n - 1)d, where
a is the first termd is the common difference between each two consecutive termsn is the position of the number∵ The recursive formula is a[tex]_{1}[/tex] = -1 and a[tex]_{n}[/tex] = a[tex]_{n-1}[/tex] - 6
→ Compare it with the formula above
∴ a = -1 ⇒ 1st term
∴ d = -6 ⇒ common difference
→ Substitute them in the form of the explicit formula
∵ a[tex]_{n}[/tex] = -1 + (n - 1)(-6)
∴ a[tex]_{n}[/tex] = -1 + (-6)(n) - (-6)(1)
∴ a[tex]_{n}[/tex] = -1 + -6n - (-6)
∴ a[tex]_{n}[/tex] = -1 - 6n + 6
→ Add the like term
∴ a[tex]_{n}[/tex] = 5 - 6n
∴ The explicit formula is a[tex]_{n}[/tex] = 5 - 6n

Recall that in football, touchdowns are worth 7 points each (including the extra point), and field goals are worth 3 points each. List all of the different ways a football team could score 63 points, if they make at least one touchdown and at least one field goal.
Answer:
The different ways a football team cold score 63 points are by having;
1) 3 touchdowns and 14 field goals
2) 6 touchdowns and 7 field goals
Step-by-step explanation:
The given parameters are;
The worth of each touchdown = 7 point
The worth of each field goal = 3 points
The number of touch down ≥ 1
The number of field goals ≥ 1
Let x represent the number of touchdowns and let y represent the number of field goals, we have;
7·x + 3·y = 63...(1)
x + y ≥ 2...(1)
Making y the subject of the equation, 7·x + 3·y = 63, gives;
3·y = 63 - 7·x
y = 21 - (7/3)·x
Making y the subject of the inequality, x + y ≥ 2, gives;
y ≥ 2 - x
From the attached graph created with Microsoft Excel, we have the points where x ≥ 1, that have a whole number value of y ≥ 0 as follows;
1) When x = 3, y = 14 gives 7×3 + 3×14 = 63
2) When x = 6, y = 7 gives 7×6 + 3×7 = 63
Therefore, the different ways a football team cold score 63 points are;
1) 3 touchdowns and 14 field goals
2) 6 touchdowns and 7 field goals.
Answer:
63 points
1) 3 touchdowns and 14 field goals
2) 6 touchdowns and 7 field goals

Answer:
The correct Option is Option A
Account B because the principal of Account B is $300 and the principal for Account A is $150
Step-by-step explanation:
Interest earned from Account A = $ 4.50
Interest earned from Account B = $22.50
Time t = 18 months
Interest rate for Account A = 2%
Interest rate for Account B = 5%
We need to find which account has greater principal
The formula used to calculate principal is: [tex]Interest=Principal\times r \times t[/tex]
where r is rate and t is time
Finding Principal for Account A:
Interest earned from Account A = $ 4.50
Time t = 18 months = 1.5 years
Interest rate for Account A = 2% = 0.02
Putting values and finding Principal
[tex]Interest=Principal\times r \times t\\4.50=Principal\times0.02\times1.5\\Principal=\frac{4.50}{0.02\times1.5} \\Principal=\frac{4.50}{0.03} \\Principal=150[/tex]
So, The Principal Amount for Account A = $150
Finding Principal for Account B:
Interest earned from Account B = $ 22.50
Time t = 18 months = 1.5 years
Interest rate for Account A = 5% = 0.05
Putting values and finding Principal
[tex]Interest=Principal\times r \times t\\22.50=Principal\times0.05\times1.5\\Principal=\frac{22.50}{0.05\times1.5} \\Principal=\frac{22.50}{0.075} \\Principal=300[/tex]
So, The Principal Amount for Account B = $300
So, the correct Option is Option A
Account B because the principal of Account B is $300 and the principal for Account A is $150
So like tell me the answer I think it’s like either 3 or 6a^9 but I’m not sure
I'm not sure what you mean by 3 or 6a^9, since there are only variables in the photo, but we can try breaking it down.
Let's start with the bottom,
a^2 * a^3 would be a^5 because for exponents you add the exponents of what's multiplied (product rule)
Then using the quotient rule, where you subtract the exponents, a^5/a^5 = a^(5-5)
And anything to the 0th power is 1, so your answer should be 1
Hope that helps!
