Answer:
x=1/3
Step-by-step explanation:
(18x+3)^2=81
square root both sides
18x+3=9
subtract 3 from both sides
18x=6
divide 18 on both sides
x=1/3

What is 1/10 equal to
Answer:
in decimal form, it is 0.1 in percent form it is 10%
Step-by-step explanation:
Garvin bought skis that cost $500 at the new store opening. The store gave him 60 days free credit. However, if he does not pay within 60 days they will charge him a 12 percent annual interest rate. How much interest will Garvin pay if he lets the account go for 90 days.
If Garvin lets the account go for 90 days, he will pay approximately $4.11 in interest.
If Garvin lets the account go for 90 days, he will exceed the 60-day free credit period by 30 days. This means he will be charged interest on the outstanding balance for those 30 days.
Since there is no information provided regarding any payments or partial payments made by Garvin within the 60-day period, we can assume that the full $500 is still outstanding.
Using the formula for simple interest:
Interest = Principal x Rate x Time
Principal = $500
Rate = 12% per year = 0.12
Time = 30 days / 365 days (since the rate is an annual rate)
Interest = $500 x 0.12 x (30/365) = $4.11 (rounded to two decimal places)
Therefore, if Garvin lets the account go for 90 days, he will pay approximately $4.11 in interest.

Find the values of x and y.
18.
120°=(2x + y)°
(2x - y)°=140°
Answer:
x = 65, y = - 10
Step-by-step explanation:
Given the 2 equations
2x + y = 120 → (1)
2x - y = 140 → (2)
Adding the 2 equations term by term will eliminate y, that is
4x = 260 ( divide both sides by 4 )
x = 65
Substitute x = 65 into either of the 2 equations and evaluate for y
Substituting into (1)
2(65) + y = 120
130 + y = 120 ( subtract 130 from both sides )
y = - 10

Find the measure of the angle.
I
[tex]4x - 5 = x + 16[/tex]
Subtract the sides of the equation plus 5
[tex]4x = x + 16 + 5[/tex]
[tex]4x = x + 21[/tex]
Subtract the sides of the equation minus x
[tex]3x = 21[/tex]
Divided the sides of the equation by 3
[tex] \frac{3}{3} x = \frac{21}{3} \\ [/tex]
[tex]x = 7[/tex]
So the measure of the angle equals :
[tex]4(7) - 5 = 28 - 5 = 23 [/tex]

Given the speeds of each runner below, determine who runs the fastest. \text{Brooke runs 13 feet per second.} Brooke runs 13 feet per second. \text{Will runs 308 feet in 26 seconds.} Will runs 308 feet in 26 seconds. \text{Ron runs 1 mile in 551 seconds.} Ron runs 1 mile in 551 seconds. \text{Debbie runs 658 feet in 1 minute.} Debbie runs 658 feet in 1 minute.
Answer:
Brooke runs the fastest.
Step-by-step explanation:
Brooke runs 13 feet per second.
Therefore, speed of Broke = 13 feet per sec.
Will runs 308 feet in 26 seconds.
Speed of Will = [tex]\frac{\text{Distance}}{\text{Time taken}}[/tex]
= [tex]\frac{308}{26}[/tex]
= 11.85 feet per second
Ron runs 1 mile in 551 seconds.
1 mile = 5280 feet
Speed of Ron = [tex]\frac{5280}{551}[/tex]
= 9.58 feet per second
Debbie runs 658 feet in 1 minute.
1 minute = 60 seconds
Speed of Debbie = [tex]\frac{658}{60}[/tex]
= 10.97 feet per seconds
Here, speed of Brooke is the maximum.
Therefore, Brooke runs the fastest.

How do I turn something like this: 3x - 2y = -16
Into a slope-intercept form?
(Whoever can explain gets Brainliest) (UwU)
[tex]3x - 2y = - 16[/tex]
Subtract sides -3x
[tex]3x - 3x - 2y = - 3x - 16[/tex]
Simplification
[tex] - 2y = - 3x - 16[/tex]
Negatives simplifies
[tex]2y = 3x + 16[/tex]
Divided sides by 2
[tex] \frac{2y}{2} = \frac{3x + 16}{2} \\ [/tex]
[tex] \frac{2}{2}y = \frac{3}{2}x + \frac{16}{2} \\ [/tex]
Simplification
[tex]y = \frac{3}{2}x + 8 \\ [/tex]
This is the slope-intercept form.

Chris rented truck for one day. There was a base fee of $16.99, and there was an additional charge of 93 cents for each mile
driven. Chris had to pay $227.17 when he returned the truck. For how many miles did he drive the truck?
Answer:
226 miles
Step-by-step explanation:
Sorry this question couldn't be answered sooner, but here is the answer now:
In order to solve this, we must first subtract the total Chris paid by the base fee:
227.17 - 16.99 = 210.18
Then, we divide this number by 0.93:
210.18 / 0.93 = 226
So, Chris drove the truck 226 miles
Hope this helps :)

The exchange rate was £1 = €1.25
Work out the cost of hiring the car in euros (€).
Answer:
The answer is £775 for hiring a car
The required answer would be the cost of hiring the car in euros is €775.
What is the Multiplication operation?In mathematics, Multiplication operations perform Multiplying values on either side of the operator.
For example 4×2 = 8
In August 2008, Eddie hired a car in Italy. The cost of hiring the car was £620
The exchange rate was £1 = €1.25
We have to determine the cost of hiring the car in euros (€).
According to the given question,
For the required solution, we have to multiply the exchange rate by the cost of hiring the car
The cost of hiring the car in euros (€) = 620 × exchange rate
The cost of hiring the car in euros (€) = 620 × €1.25
Apply the multiplication operation to get
The cost of hiring the car in euros (€) = €775
Therefore, the required answer would be the cost of hiring the car in euros is €775.

the ratio is 2:11
Step-by-step explanation:
I already wrote this in a comment, but I'm writing it here because the other person's answer was deleted.

x–2(x+1)+3(x+2)=x–4
(show work too please)
Answer:
x = -12
Step-by-step explanation:
x-2(x+1)+3(x+2) = x-4 (equation)
x-2x+2+3x+6 = x-4 (simplify)
2x+8 = x-4 (combine like terms)
x+8 = -4 (subtract x from both sides)
x = -12 (subtract 8 from both sides)
A cell phone company charges $4 per GB beyond 20GB in a month. The monthly plan is $59.99, and the bill for January is $75.99. How many GB were used in that month?
Answer:
24GB
Step-by-step explanation:
75.99-59.99=16 This is how much extra money was paid.
16/4=4 Divide this by the cost per GB.
20+4=24GB Add the 20GB included in the plan.
Answer:
Step-by-step explanation:
75.99-59.99=16
$16 worth of GB used for that month
which means 16/4=4 GB extra were used that month beyond the 20 GB
so total GB usage for that month is 24 GB

A pyramid of logs has 2 logs in the top row, 4 logs in the second row from the top, 6 logs in the third row from the top, and so on, until there are 200 logs in the bottom row. Is the pattern an arithmetic sequence? Identify a and d. Write the 50th term of the sequence. Find the total number of logs in the first 10 rows.
Answer:
1) Is the pattern an arithmetic sequence?
Yes it is
2)Identify a and d.
a = First term = 2
d = Common difference = 2
3) Write the 50th term of the sequence.
50th term = 100
4) Find the total number of logs in the first 10 rows.
= 1010 logs
Step-by-step explanation:
Is the pattern an arithmetic sequence?
Yes it is
2) Identify a and d.
A pyramid of logs has 2 logs in the top row, 4 logs in the second row from the top, 6 logs in the third row from the top, and so on,
The formula for arithmetic sequence =
an = a+ (n - 1)d
a = First term
d = Common difference
For the above question:
a = 2
d = Second term - First term
= 4 - 2
d = 2
3) Write the 50th term of the sequence.
Using the formula for arithmetic sequence
an = a+ (n - 1)d
a = 2
n = 50
d = 2
a50 = 2 + (50 - 1)2
= 2 + (49)2
= 2 + 98
= 100
The 50th term = 100
4)Find the total number of logs in the first 10 rows.
Sum of first n terms = n/2(a + l)
n = 10
a = first term = 2
We are told that there are 200 logs in the bottom row, hence:
l = last term = 200 logs
Hence,
Sn = 10/2×[ (2 + 200
= 5(202)
= 1010 logs
