Answer:
She made a profit of 1,335 cedis
Step-by-step explanation:
Here, we want to calculate the profit made
Profit is selling price - cost price
Her cost price is 65 credits
For her selling price;
she sells 3 for 20 cedis
So the price she sold 210 will be;
(210 * 20)/3 = 1,400 cedis
So the profit made is;
1,400-65 = 1,335 cedis

in 2010 an item cost $200. The price increase by 1.5% each year. How much wil it cost in 2030?
Round
your
answer to the nearest cent.
Step-by-step explanation:
Let P be price after t year . From the formula of compounding
P = 9 (1.015)^t
Taking log to the base e on both sides
ln P = ln 9 + t ln 1.015
= (2.197 + .0149t )
P = e^{(2.197+.0149t)}

A small company has one color printer and one black-and-white printer, each printing at different rates. The color printer, working for 5 minutes and the black-and-white printer working, working for 3 minutes, print a total of 70 pages. When the black-and-white printer works for 6 minutes and the color printer works for 9 minutes, they print a total of 135 pages. This is modeled by the situation below, where b is the number of pages per minute of the black-and-white printer and c is the number of pages per minute of the color printer 3b + 5c = 70 and 6b + 9c = 135 How many pages per minute does the black-and white printer print?
Answer:
The black-and white printer print can print 15 pages per minute.
Step-by-step explanation:
The given modeled equations are
3b + 5c = 70...(i)
6b + 9c = 135...(ii)
where b is the number of pages per minute of the black-and-white printer and c is the number of pages per minute of the color printer.
From equation (i), we have
[tex]3b=70-5c \\\\\Rightarrow b = \frac {70-5c}{3} \cdots(iii)[/tex]
Now, substitute the value of b in equation (ii), we have
[tex]6\times \frac {70-5c}{3}+9c=135 \\\\\Rightarrow 2(70-5c)+9c=135 \\\\\Rightarrow 140 - 10c+9c=135 \\\\\Rightarrow -c=135-140=-5 \\\\\Rightarrow c=5x^{2}[/tex]
By using equation (iii), we have
[tex]b = \frac {70-5\times5}{3}=\frac{45}{3}=15[/tex]
Hence, the black-and white printer print can print 15 pages per minute.
The black-and-white printer can print 15 pages per minute.
Given equations:
[tex]3b+5c=70[/tex] ........(i)
[tex]6b+9c=135[/tex] ........(ii)
Where b is the number of pages per minute of the black-and-white printer and c is the number of pages per minute of the color printer.
Solve the system of equations by substitution method
From (ii)
[tex]6b=135-9c\\b=\frac{135-9c}{6}[/tex] ........(iii)
Put the value of b in (i), we get
[tex]3(\frac{135-9c}{6} )+5c=70\\\frac{135-9c}{2} +5c=70\\135-9c+10c=140\\c=5[/tex]
put c = 5 in (iii)
[tex]b=\frac{135-9(5)}{6} =\frac{90}{6} =15[/tex]
Therefore, The black-and-white printer can print 15 pages per minute.

Answer:
x = 0
Step-by-step explanation:
If one were to fold this figure in half over the line x = 0, then one would end up with a single figure, with no overhang. Hence x = 0 is the line of symmetry. Note; x = 0, can also be called the y-axis.
Answer:
Option D) x = 0
Step-by-step explanation:
Axis of symmetry is a line that divides an object into two equal halves, thereby creating a mirror-like reflection of either side of the object. Here we see that the object's Axis of symmetry is the line x =0
The line x = 0,1,2,3,4,5,..... and so on are all vertical lines and
The line y=0,1,2,3,4,5,..... and so on are all horizontal lines
In this this case the line x = 0 is the Axis of symmetry which divides the object in two equal halves.

c The rectangle is 3 times as long as it is wide.
Construct and solve an equation to find the longest side length
of the rectangle.
Answer:
To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. Then find the answer.

5.1 is 102% of what number?
Answer:
it is 5
Step-by-step explanation:
102% x 5 =5.1
if you times each answer with you percentage you get the answer
Using the principle of percentage approximation, the value of the number, n is 5
Let the number = n
We then write the expression thus :
(102/100) × n = 5.1
1.02n = 5.1
n = 5.1 / 1.02
n = 5
Therefore, the number, n in which 102% gives a value of 5.1 is 5

Answer:
These are similar triangles.
By changing the length of the base of the corresponding triangle, the 3 interior angles of this triangle remain equal to the original
Therefore, if these triangles are similar, their corresponding sides must give equal ratios to each other:
This means that BF/FE = BC/CD=FC/ED
The total length of line segment BD=BC+CD; BC=6, CD=42; BD=6+42, BD=48
BE=BF+FE; BE=9+?
if BF/FE=BC/CD then 9/BE=6/42; 6/42=3/21 or 1/7. 9/BE=1/7; 1/7=9/BE
1x9=9, 7x9=63
63=BE
Step-by-step explanation:
Answer:BE is equal to 72.
Step-by-step explanation: They are similar triangles. We know CD and BC. So we can find the comparison between the two. And we see that BC x 7 = CD. So the same will be said for BF and FE. We have BF is equal to 9. So 9 x 7 = 63. However, now we need to add the two together in order to get BE. Because BF + FE = BE. So 9 + 63 = 72

A rectangle and an equilateral triangle have the same perimeter. The perimeter of the rectangle is 6 ( 1 2 x + 5 ) inches. The perimeter of the triangle is 4 ( x − 2 ) inches. What is the perimeter of each figure?
Answer:
-328/34
Step-by-step explanation:
Here,
Perimeter of rectangle = 6(12x+5)
Perimeter of equilateral triangle = 4(x-2)
Since they are equal, 6(12x+5) = 4(x-2)
or, 72x + 30 = 4x - 8
or, 68x = -38
or, x= -38/68 or -19/34
Now,
Area of triangle ( or rectangle whichever you prefer)
= 4* -19/34 - 8
= -76/34 - 8
= - 328/34

ill give brainliest
Answer:
c - 4.3 > 16
(hope this helps)
The inequality representing a number c minus 4.3 is no less than 16 is c - 4.3 > 16.
What is inequality?The relationship between two values that are not equal is described by inequalities. Equal does not necessarily mean unequal. The "not equal symbol" is typically used to denote that two values are not equal.
As the condition is suggesting c - 4.3 is no less than 16 means it is greater than 16,
So, c - 4.3 > 16
Therefore, the inequality representing a number c minus 4.3 is no less than 16 is c - 4.3 > 16.
