Johnny has $100 in the bank and plans to deposit $15 per day. Sal has $250
in the bank and plans to withdraw $10 from the bank each day. How many days
until they have the same amount in the bank?
Answers
Answer:
6 days
Step-by-step explanation:
First we have to write an expression that represents Johnny's and Sal's banking plans.
Johnny: He has an initial value of $100 and that value will increase by $15 every day. So the expression looks like: 15x + 100, where x is the amount of days it's been.
Sal: An initial value of $250 and the value will decrease by $10 everyday. The expression looks like: -10x + 250, where x is the amount of days it's been.
To find how many days they have until they have the same amount of money in the bank, we can set the expressions equal to each other and solve for x:
15x + 100 = -10x + 250
Add 10x to both sides to isolate the x on one side of the equation:
25x + 100 = 250
Subtract 100 from both sides of the equation to isolate 25x:
25x = 150
Divide both sides by 25 to find the value of x:
x = 6
Since x represents the amount of days it's been, x = 6 means that it will take 6 days for their bank accounts to have the same amount of money in them.

A circus audience sits in rows around the performing ring. There are 9 seats in each row. How many rows will need to be set up if 513 people are expected to attend the show?
Answers
Answer:
57 rows
Step-by-step explanation:
Since each row will have a total of 9 seats, then we would simply need to divide the total number of individuals that will attend the show by 9 in order to calculate the number of rows that need to be set up around the performing ring.
513 / 9 = 57 rows
Therefore, we can see that we would need a total of 57 rows of 9 chairs each in order for there to be enough chairs to seat 513 people.
Refer to the various selling prices of various homes in a community that follow the normal distribution with mu (population mean) = $276,000 and sigma (standard deviation – measure of dispersion) = $32,000. Calculate the probability that the next house in the community will sell for between $276,000 and $325,000.
Answers
Answer:
0.43715
Step-by-step explanation:
We solve using z score calculator
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = $276,000
σ is the population standard deviation = 32,000
For x = $276,000
z = 276,000 - 276,000/32000
z = 0
Probability value from Z-Table:
P(x = 276000) = 0.5
For x = $325,000
z = 325,000 - 276,000/32000
z = 1.53125
Probability value from Z-Table:
P(x = 325000) = 0.93715
The probability that the next house in the community will sell for between $276,000 and $325,000 is
P(x = 325000) - P(x = 276000)
= 0.93715 - 0.5
= 0.43715

Is the following sequence arithmetic?
23, -7, -37, -67, ...
True
Or
False
Answers
Answer:
TRUEStep-by-step explanation:
In arithmetic sequence the difference (d) between any pair of next and previous term is the same.
-7-23 = - 30
-37 - (-7) = -37+7 = - 30
-67 - (-37) = -67 +37 = - 30
d = -30
So this is arithmetic sequence.

Answer:
X = 12
Step-by-step explanation:
Since each angle is equivalent to each other, you can write the equation:
(9x-3) = (7x+21)
Then Simplify.
Subtract both sides by 7x
2x-3=21
Add 3 To Both Sides
2x=24
Divide by 2
X = 12
Answer:
9x-3=7x+21
9x=7x+24
2x=24
x=12
Step-by-step explanation:
(9x-3) and (7x+21) are corresponding angles that means that they are congruent. So they equal each other.

Ingrid said, “First, I'll subtract x from both sides so I have x^2-4x=1. Then I can solve by completing the square. If I add 4 to each side, I can rewrite the equation as (x-2)^2=5. Harish said, “I'll isolate the x^2x term by adding 3x to both sides of the equation. Then I'll solve by taking the square root.”
