The value of n in the equation is 1
Step-by-step explanation:
The equation is [tex]-\frac{1}{2}[/tex] (2n + 4) + 6 = -9 + 4(2n + 1)
At first we must do that:
1. Open the brackets in both sides
2. Add like terms
3. Solve to find n
L.H.S:
∵ [tex]-\frac{1}{2}[/tex] (2n + 4) + 6 = -n - 2 + 6
∴ [tex]-\frac{1}{2}[/tex] (2n + 4) + 6 = -n + 4
R.H.S:
∵ -9 + 4(2n + 1) = -9 + 8n + 4
∴ -9 + 4(2n + 1) = 8n - 5
∴ -n + 4 = 8n - 5
- Add 5 to both sides
∴ -n + 9 = 8n
- Add n to both sides
∴ 9 = 9n
- Divide both sides by 9
∴ n = 1
The value of n in the equation is 1

Step-by-step explanation:
Connor is stuck in a traffic jam on a single-lane road. The traffic report tells him the traffic jam stretches for 5.5 miles. If Connor assumes each car is about 12.5 feet long, which calculation is most reasonable for Connor to use to find about how many cars are stuck in the traffic jam?
Connor can reasonably estimate that about 2323 cars are stuck in the traffic jam.
To find about how many cars are stuck in the traffic jam, Connor can divide the total length of the traffic jam by the length of each car.
Given:
- Length of traffic jam: 5.5 miles
- Length of each car: 12.5 feet
First, let's convert the length of the traffic jam from miles to feet since the length of each car is given in feet.
1 mile = 5280 feet
So, the length of the traffic jam in feet is:
[tex]\[ 5.5 \text{ miles} \times 5280 \text{ feet/mile} = 29040 \text{ feet} \][/tex]
Now, Connor can divide the total length of the traffic jam by the length of each car to find about how many cars are stuck:
[tex]\[ \frac{29040 \text{ feet}}{12.5 \text{ feet/car}} \approx 2323 \text{ cars} \][/tex]

As a smart consumer, you are always on the lookout for sales, coupons, and rebates. While shopping for new clothes, you notice that one particular brand of shirts is on sale for 20% off the original price. You also have a coupon for $10 off a $40 purchase. Coupons are applied after the 20% discount is taken. If each shirt originally costs $17.99, how many shirts would you need to buy to be able to use your coupon? Show your work
You’d have to buy 3 shirts, with the 20% off the shirts would come out to $14.39. So $14.39 x 3 = $43.17. Now with the $10 off a $40 purchase your total cost would be $33.17.
Answer:
You'd have to buy 3 shirts in order to use your coupon.
Step-by-step explanation:
Each shirt originally costs $17.99
One particular brand of shirts is on sale for 20% off the original price.
$17.99*0.2= $3.60 (amount taken off for each shirt)
Now subtract $3.60 from $17.99.
$17.99 - $3.60 = $14.39 (per shirt)
40 / 14.39 = 2.779 (round to 3)
You'd have to buy 3 shirts in order to use your coupon.
$14.39 * 3 = $43.17, in order to get $10 off you'd need to spend at least $40

Kieran has $45.00 to purchase supplies to paint the top of a square wooden platform for the school play. The paint roller costs $9.75, and the paint is $17.00 per can. If one can of paint covers approximately 375 square feet, what is the maximum possible length, in feet, of
one side of the wooden platform to the nearest tenth of a foot?
F. 27.3
G. 27.4
H. 27.5
J. 28.0
K. 28.1
Answer:
Option G. 27.4 ft
Step-by-step explanation:
step 1
Calculate the maximum number of cans of paint Kieran can buy with $45
Let
x -----> the number of cans of paint
we know that
The number of cans of paints multiplied by it cost plus the cost of a rooler paint must be less than or equal to $45
so
[tex]9.75+17.00x \leq 45[/tex]
Solve the inequality for x
Subtract 9.75 both sides
[tex]17.00x \leq 45-9.75[/tex]
[tex]17.00x \leq 35.25[/tex]
Divide by 17 both sides
[tex]x \leq 2.07\ cans[/tex]
so
The maximum number of cans that Kieran can purchase is 2 cans
step 2
Find the maximum area covered with 2 cans of paint
we know that
One can of paint covers approximately 375 square feet
therefore
To find out the area covered with 2 cans multiply 375 by 2
[tex]375(2)=750\ ft^2[/tex]
step 3
Find the maximum possible length side of the wooden platform
we know that
The wooden platform is in the shape of a square
so
The area of a square is
[tex]A=b^{2}[/tex]
where
b is the length side of the square
we have
[tex]A=750\ ft^2[/tex]
substitute and solve for b
[tex]750=b^{2}[/tex]
square root both sides
[tex]b=27.4\ ft[/tex]
Suppose 0 is an angle in the standard position whose terminal side is in Quadrant 1 and sin 0= 84/85. Find the exact values of the five remaining trigonometric functions of 0

Part 3) [tex]cot(\theta)=\frac{13}{84}[/tex]
Part 4) [tex]sec(\theta)=\frac{85}{13}[/tex]
Part 5) [tex]csc(\theta)=\frac{85}{84}[/tex]
Step-by-step explanation:
we know that
Angle [tex]\theta[/tex] lie on Quadrant I
so
[tex]sin(\theta)[/tex] is positive
[tex]cos(\theta)[/tex] is positive
[tex]tan(\theta)[/tex] is positive
[tex]cot(\theta)[/tex] is positive
[tex]sec(\theta)[/tex] is positive
[tex]csc(\theta)[/tex] is positive
step 1
Find the value of [tex]cos(\theta)[/tex]
we have
[tex]sin(\theta)=\frac{84}{85}[/tex]
we know that
[tex]sin^2(\theta)+cos^2(\theta)=1[/tex]
substitute
[tex](\frac{84}{85})^2+cos^2(\theta)=1[/tex]
[tex](\frac{7,056}{7,225})+cos^2(\theta)=1[/tex]
[tex]cos^2(\theta)=1-(\frac{7,056}{7,225})[/tex]
[tex]cos^2(\theta)=(\frac{169}{7,225})[/tex]
[tex]cos(\theta)=(\frac{13}{85})[/tex]
step 2
Find the value of [tex]tan(\theta)[/tex]
we know that
[tex]tan(\theta)=\frac{sin(\theta)}{cos(\theta)}[/tex]
we have
[tex]sin(\theta)=\frac{84}{85}[/tex]
[tex]cos(\theta)=(\frac{13}{85})[/tex]
substitute
[tex]tan(\theta)=\frac{(84/85)}{(13/85)}[/tex]
[tex]tan(\theta)=\frac{84}{13}[/tex]
step 3
Find the value of [tex]cot(\theta)[/tex]
we know that
[tex]cot(\theta)=\frac{1}{tan(\theta)}[/tex]
we have
[tex]tan(\theta)=\frac{84}{13}[/tex]
therefore
[tex]cot(\theta)=\frac{13}{84}[/tex]
step 4
Find the value of [tex]sec(\theta)[/tex]
we know that
[tex]sec(\theta)=\frac{1}{cos(\theta)}[/tex]
we have
[tex]cos(\theta)=(\frac{13}{85})[/tex]
therefore
[tex]sec(\theta)=\frac{85}{13}[/tex]
step 5
Find the value of [tex]csc(\theta)[/tex]
we know that
[tex]csc(\theta)=\frac{1}{sin(\theta)}[/tex]
we have
[tex]sin(\theta)=\frac{84}{85}[/tex]
therefore
[tex]csc(\theta)=\frac{85}{84}[/tex]
13/16 as a decimal rounded to the nearest tenth
The decimal equivalent of the fraction 13/16 is 0.8125. However, when you round this to the nearest tenth as the question specifies, you get 0.8.

13/16 as a decimal rounded to the nearest tenth is 0.8.
To convert the fraction 13/16 to a decimal and round it to the nearest tenth, we can follow these steps:
First, divide 13 by 16. When you do this, you get 0.8125 because 13 ÷ 16 = 0.8125.Next, we round 0.8125 to the nearest tenth. To do this, look at the hundredths place (which is the second digit after the decimal point). Here, it’s 1. Since this digit is less than 5, we round down, keeping the tenths place the same.Therefore, 0.8125 rounded to the nearest tenth is 0.8.Explain how you can use multiplication to find the quotient 3/5 ÷ 3/15 then evaluate

Manuel took 2 2/5
hours to clean the den. He took 1 1/3
hours to clean the bathroom. How much longer did it take Manuelt
clean the den?
It took Manuel approximately 1.07 hours longer to clean the den compared to the bathroom. This was calculated by converting the mixed numbers to improper fractions and subtracting.
Explanation:In this problem, we are comparing the time it took Manuel to clean the den and bathroom. To do this, we need to subtract. Firstly, you need to convert the mixed numbers, 2 2/5 hours and 1 1/3 hours, into improper fractions for ease. This would be 12/5 hours and 4/3 hours respectively. Now we subtract 4/3 from 12/5. You can use the least common denominator (LCD) to make this easier: 12/5 (which is 2.4 in decimal) minus 4/3 (which is 1.33 in decimal) equals approximately 1.07 hours. It means Manuel took 1.07 hours(approximately) longer to clean the den compared to the bathroom.

Find the nth term of this number sequence
1, 10, 19, 28, ...
Pls help
Answer:
9n - 8
Step-by-step explanation:
The sequence is arithmetic since the difference between consecutive terms is common
d = 10 - 1 = 19 - 10 = 28 - 19 = 9
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 1 and d = 9, thus
[tex]a_{n}[/tex] = 1 + 9(n - 1) = 1 + 9n - 9 = 9n - 8, hence
[tex]a_{n}[/tex] = 9n - 8
We are required to find the nth term of the sequence 1, 10, 19, 28,....
The nth term of the sequence 1, 10, 19, 28, is 9n - 8
Given:
1, 10, 19, 28,
First term, a = 1
Common difference, d = difference between consecutive terms
10 - 1 = 9
19 - 10 = 9
28 - 19 = 9
nth term = a + (n - 1)d
nth term = 1 + (n - 1)9
= 1 + 9n - 9
= 9n - 8
Therefore, nth term of the sequence 1, 10, 19, 28, is 9n - 8
