Ruben can paint 6 1/2 square meters per hour at the same rate how many square meters can he paint in 2 1/2 hour.?
Answer:
The number of square meters that Ruben can pain in 2 1/2 hours is:
16 1/4m²
Step-by-step explanation:
a) Data and Calculations:
Number of square meters that Ruben can pain in one hour = 6 1/2m²
Therefore, every 1/2 half he can paint 3.25m² or 3 1/4m²
In two hours, he can pain 6 1/2m² * 2 = 13m²
Using the same rate, in 2 1/2 hours, he can pain =xm² (0r 13m² + 3 1/4m²)
x = 6.5 * 2.5
= 16.25
= 16 1/4m²
b) Since Ruben can paint 6 1/2m² in one hour, he can then paint more square meters, multiplied by 2.5 in 2 1/2 hours. This means that he will be doubling the square area he can paint in 2 hours and painting half of the square area in 1/2 hour's time, given his speed.
How many square meters can he paint in 2 1/2 hour is 65/4 square meters
Given:
Square meters per hour= 6 ½
Number of hours =2 ½
Let x represent how many square meters he can paint in 2 1/2 hour
First step is to convert the mixed numbers to improper fractions
6 ½= 13/2
2 ½ = 5/2
Now let determine how many square meters he can paint in 2 1/2 hour
x=(13/2)× (5/2)
x= 16.25 or 65/4
Inconclusion How many square meters can he paint in 2 1/2 hour is 65/4 square meters.

Determine the slope and y-intercept of each graph. Then, write the equation of the graph in slope-intercept form.
Answer:
slope= -2/1
y int= (0,2)
equation= Y= -2/1x+2
Step-by-step explanation:
Answer:
Slope: 1/3x (over one up three)
Y intercept: (0,2)
Equation: y=1/3x+2
Step-by-step explanation:
y=1/3x+2 is the equations...X is always the slope and the 2 is the y.
(0,2) is the Y intercept because that is where it crosses the Y axis.
slope: 1/3x (over one up three)

Steve opens a bank account. The amount, in dollars, in the account x weeks after the account is opened can be modeled by function f. If Steve has $5,000 in the account 20 weeks after the account is opened, which TWO of the following must be true?
The missing options are:
[tex]A.\ f(20) =5,000[/tex]
[tex]B.\ f(5000) = 20[/tex]
C. In the xy plane, point (20, 5,000) is on the graph y = f(x).
D. In the xy plane, point (5,000,20) is on the graph y = f(x)
Answer:
[tex]A.\ f(20) =5,000[/tex]
C. In the xy plane, point (20, 5,000) is on the graph y = f(x).
Step-by-step explanation:
Given
Represent amount with y and weeks with x
So, we have:
x = 20 when y = 5000
Required
Select 2 correct options
A point on a graph can be illustrated using [tex](x,y)[/tex]
So, when x = 20 and y = 5000 ----- given
[tex](x,y)[/tex] implies that:
[tex](x,y) = (20,5000)[/tex]
We got [tex](20,5000)[/tex] by substituting 20 for x and 5000 for y
From the list of given options, the above represented of (x,y) is illustrated in option C
Represent (x,y) as a function, we have:
[tex]y = f(x)[/tex]
Substitute values for x and y
[tex]5000 = f(20)[/tex]
Reorder
[tex]f(20) = 5000[/tex]
The above is illustrated in option A
Hence, A and C answers the question

Pauline Romer has taken a $100000 mortgage loan on her house at an interest rate of 3 percent per year. If the mortgage calls for 20 equal annual payments, what is the amount of each payment?
Answer:
5000
Step-by-step explanation:
Using the mortgage interest principle, the amount of equal payment to be made ls $8000
Mortgage payment = $100000
Interest rate = 3%
The total amount to repayed can be calculated thus :
Mortgage payment × interest rate × timeNumber of annual payments = 20
Total repayment = 100000(1 + (0.03 × 20))
Total repayment = 100000 + 60000 = $160,000
Amount of each payment = $160000 / 20 = $8000
Therefore, the amount to be repayed annually is $8000
