Apartment buildings are required to have a fire extinguisher (extintor de incendios) every 600 feet. If a building has a total of 13,500 feet, how many fire extinguishers are needed?
Given:
Apartment buildings are required to have a fire extinguisher every 600 feet.
Height of building = 13,500 feet
To find:
The number of fire extinguishers are needed.
Solution:
Building needs a fire extinguisher every 600 feet.
Height of building = 13,500 feet
So, required number of fire extinguishers is
[tex]n=\dfrac{\text{Total height of building}}{600}[/tex]
[tex]n=\dfrac{13500}{600}[/tex]
[tex]n=\dfrac{135}{6}[/tex]
[tex]n=22.5[/tex]
Number of fire extinguishers cannot be negative.
[tex]n\approx 23[/tex]
Therefore, 23 number of fire extinguishers are needed.

Answer:
The expression x² + 8x + 7 can be factored out as (x + 7)(x + 1).
Step-by-step explanation:
You can see how this factors by looking at the last term, and the coefficient of the second term. You need to find two numbers that multiply to make seven, and add to make eight.
Because seven is a prime number, this becomes very easy. If this works at all, the numbers must be seven and one.
And lo, if you check, seven and one do indeed add up to be eight, so that's what we need to use. Let's do it:
x² + 8x + 7
= x² + x + 7x + 7
= x(x + 1) + 7(x + 1)
= (x + 7)(x + 1)

y=x²+1
y=0.75x+2
y=0.5x³
Answer:
y=3x - Linear Function
y=4x-1 - Linear Function
y=x²+1 - Non-Linear Function
y=0.75x+2 - Linear Function
y=0.5x³ - Non-Linear Function
(For a function to be linear, both x & y must equal 1.)
If each letter represents a different nonzero digit,what must Y be?
A. 7
B. 6
C. 9
D. 8
Answer:
D
Step-by-step explanation:
With only 4 options, I substituted the possible numbers for Y. When substituting Y for 8, the right hand column wrote:
8 - Z = 4
Another way to think of this is 8 - 4 = 4.
When using 8, Z must equal 4.
Take this information to the left hand column.
8 - Z = Z
We know Z equals 4 so plug this information in. Is it correct?
8 - 4 = 4
This is correct.
Therefore, the answer is 8, or D.

Step-by-step explanation:
Myra gets paid at home for doing extra chores. Last week, she did 5 loads of laundry and 8 loads of dishes, and her parents paid her $18. The week before, she finished 4 loads of laundry and 6 loads of dishes, earning a total of $14. How much does Myra earn for completing each type of chore?
Answer: Laundry = $2
Dishes= $1
Step-by-step explanation:
Let the amount paid for doing laundry be x
Let the amount paid for doing dishes be y.
Based on the information in the question, this can be formed in an equation as:
5x + 8y = 18 ..... i
4x + 6y = 14 ...... ii
Multiply equation i by 4
Multiply equation ii by 5
20x + 32y = 72 ...... iii
20x + 30y = 70 ...... iv
Subtract iv from iii
2y = 2
y = 2/2 = 1
Dishes cost $1
Since 5x + 8y = 18
5x + 8(1) = 18
5x = 18 - 8
5x = 10
x = 2
Laundry cost $2

Which of the following equations best represents the line of best fit for the data in the scatterplot?
Answer:
the answer is b bc the line is positive
Step-by-step explanation:
The equation that best represents the line of best fit is -
y = (1/2)x - 1
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have the line of best fit for the data in the scatterplot.
The line passes through the points -
(0, - 1) and (2, 0).
Then, the slope will be -
m = 1/2
and the [y] - intercept is -1. So the equation that best represents the line of best fit is -
y = (1/2)x - 1
Therefore, the equation that best represents the line of best fit is -
y = (1/2)x - 1

Regular tickets cost 34.50 and vip tickets cost 78.50 a total of 810 tickets were sold, and a total ticket sales were 29,045. The equation 34.50r + 78.50 (810-r)= 29,045 can be used to determine the number of regular tickets r sold to the concert. How many of each type of ticket were sold?
Answer:Number of regular tickets=785
Number of VIP tickets=25
Step-by-step explanation:
Step 1
Cost of Regular tickets=34.50
Costs VIP tickets =78.50
Total tickets sold =810
Cost of both rockets sold=29,045
Using the the given equation that 34.50r + 78.50 (810-r)= 29,045 to determine the number of regular tickets, we have that
Step 2---Solving
34.50r + 78.50 (810-r)= 29,045
34.50+63,585 - 78.50r=29,045
63585-29045=78.50r-34.50r
34,540=44r
r=34540/44
r=785=Number of regular tickets
Number of regular tickets+Number of VIP tickets =810
Number of VIP tickets=810-785=25

Current price = $52
Discount = $65 - $52
Discount = $13
The percentage discount is calculated as:
Discount/Original price × 100
= $13/$65 × 100
= 20%
The percentage discount for the cost of the book is 20%

Mortgage loan of $46,000.00.
Interest rate is 5 percent.
Monthly payment is $269.10.
How much of the first monthly payment is for interest?
Answer: $191.67
Step-by-step explanation:
When paying back mortgages, the monthly payment has two components: an interest payment component and a principal repayment component.
The interest payment component is based on the total amount of debt still to be paid at the time and the principal repayment component is the rest of the payment after the interest has been deducted.
This interest is in a yearly rate so should be combined to a monthly rate as the payments are monthly:
= 5% / 12
= 5/12%
Interest = Mortgage remaining * interest rate
= 46,000 * 5/12%
= $191.67
