Answer:
p=1/5t
Step-by-step explanation:
Since t is 100% of the items sold and p is 20% of that, the profit, p is 20% of t, or 1/5t.
Answer:
p = t(0.2)
Step-by-step explanation:
The profit is 20% of the total price. So if you multiply the total price by 0.2, you will get 20% of the total price which is the profit.
Use a product of two binomials to find a polynomial that represents the area of Roberto's plot.
Answer:
First, we know that the area of a rectangle of width W and length L is:
A = W*L
In the case of Roberto's plan, we can see that the length of the whole rectangle is:
L = 1.5ft + x + 1.5ft = 3 ft + x
And the width is:
W = 3ft + x + 3ft = 6ft + x
Then the area of the whole thing is:
A = (3ft + x)*(6ft + x)
This is what we wanted, a product of two polynomials that represents the area of Roberto's plot.
Now if we subtract the white square (is a square of sidelength x, then its area is A = x*x) we will get the area of the border;
The total area of Roberto's borders is:
Area of the border = (3ft + x)*(6ft + x) - x*x
= 3ft*6ft + 3ft*x + x*6ft + x^2 - x^2
= x*9ft + 18ft^2

Which of the following is most likely the next step in the series?
Answer:
its either A, or B
Step-by-step explanation:
hehehhe
Answer:
B
Step-by-step explanation:
The numbers in each of the circle halves are all in the blue side therefore all numbers on the red side would be eliminated. Leaving you with the options of B or C.
Now the Blue side for every pair is facing each other. So C would be eliminated because the red side is facing the start of the second pair ( A.K.A the third circle)
Leaving us with B.

Answer:
The true statements are;
A. The point (0, -3) is on the line
C. The point (-6, -6) is a point on the line
Step-by-step explanation:
The question relates to the finding of the equation of a straight line graph
The x-intercept of the graph is (6, 0) and the graph passes through the point (2, -2)
Therefore, the slope of the graph is m = (-2 - 0)/(2 - 6) = 0.5
The equation of the graph in point and slope form is given as follows;
y - 0 = 0.5 × (x - 6)
∴ y = 0.5·x - 3
Therefore, the equation of the graph in slope and intercept form, y = m·x + c is also y = 0.5·x - 3
A. The y-intercept of the graph is (0, -3), therefore, the point (0, -3) is on the line
B. The equation of the graph, y = 0.5·x - 3, can be written as follows;
8·y = 8 ×0.5·x - 8 × 3 = 4·x - 24
∴ 8·y - 4·x = -24
C. When y = -6, 'x' is given as follows;
y = 0.5·x - 3
-6 = 0.5·x - 3
0.5·x = -6 + 3 = -3
x = -3/0.5 = -6
x = -6
Therefore, when y = -6, x = -6, and (-6, -6) is a point on the line
D. When x = 0, 'y', is given as follows;
y = 0.5·x - 3
When x = 0, y = 0.5 × (0) - 3 = -3
Therefore the point (0, -3) is on the line and the point (0, -4) is not on the line
E. The point (-6, 0) represent an x-intercept of a line graph, however the x-intercept on the given line is (6, 0) and when y = 0 on the line, x = 6
Therefore, the point (-6, 0) is not on the line
F. The equation of the graph is 8·y - 4·x = -24, therefore, - 4·x + 8·y = 24 does not represent the equation of the graph
What is the domain of the function?
X+6
f(x)=(x-7)(x+5)
A all real numbers except 7
Ball real numbers except 5 and -7
Call real numbers except -5 and 7
D all real numbers
The required domain of the function is all real numbers except -5 and 7. Option C is correct.
Given that,
f(x) = (x + 6) /[(x-7)(x+5)]
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
here,
Given function,
f(x) = (x + 6) /[(x-7)(x+5)]
We can put any real number on the number line except 7 and -5, because at these value function gives the value as infinity.
Thus, the required domain of the function is all real numbers except -5 and 7. Option C is correct.

$15,000 at 15% compounded annually for 5 years
A. $28,500.00
0
B. $30,170.36
C. $17.250.00
ОО
D. $26,250.45
Answer:
p=$15000
R=15%
t=5years
compound amount CI=?
Step-by-step explanation:
we have
CI=p(1+R/100)^t=$15000(1+15/100)^5=$15000×1/15^5=$30170.35The total amount of $15,000 at 15% compounded annually for 5 years will be $30,170.36 so option (B) is correct.
What is compound interest?Compound interest is applicable when there will be a change in principle amount after the given time period.
The rate at which compound interest accrues depends on the frequency of compounding.
For instance, if you offer someone $500 at a rate of 10% annually, $500 will be considered your principal sum. After a year, the interest will be $50, making the principle amount $550. Moving forward, the interest will be $550 rather than $500.
Given
Principle amount = $15000
Rate of interest = 15%
The time period T = 5 years.
Compound interest formula
A = P [tex][ 1 + R/100 ]^{T}[/tex]
A = 15000 [tex][ 1 + 15/100 ]^{5}[/tex]
A = $30,170.36 hence, the total amount after 5 year will be $30,170.36.

Is 1 3/23 a rational number
Answer:
Yes
Step-by-step explanation:
In mathematics rational means "ratio like." so a rational number is one that can be written as the ratio of two integers. 1 3/23 can be converted into 26/23, which is a ratio, therefore, 1 3/23 is a rational number.

If 30% of a number is 15, what is 25% of the number?
Answer:
12.5
Step-by-step explanation:
Basically, the number was multiplied by .3 to get 15. So if you do 15/.3 you'll get your original number which is 50. Then you multiply by .25 and get 12.5.

Write the equation of a line with a slope of -7/2 passing through the point 2,-4
Answer:
y = -7/2x+3
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = -7/2 x+b
Substitute the point into the equation
-4 = -7/2(2) +b
-4 = -7+b
Solving for b
-4+7 = -7+b+7
3 = b
The equation is y = -7/2x+3
