The circumference of a circle is 25 m. What is the area, in square meters?
Express your answer in terms of .
The area of a circle given its circumference is 49.48 m^2.
The circumference of a circle is 25 m.
Step-by-step:
Use the formula for circumference: Circumference = 2πr, where r is the radius.
Given Circumference = 25 m, then find the radius using the formula: 25 = 2πr.
Calculate the radius: r = 25 / (2π).
Once you find the radius, use the formula for the area of a circle:
Area = πr^2
= π * 25/2π * 25/2π
= 625/(4 * 3.14)
= 49.48 m^2
Therefore, the area of the circle is approximately 49.48 m^2.

Find the polynomial M if 2x^2− 1/3 ax+by−M=0.
Find the polynomial B if 3x^2y− 1/3 xy^3+cy+B=0.
The Y for the second equation is not an exponent.
Thank You
Answer:
M = 2x² - (ax/3) + by
B = - 3x²y + (xy³/3) - cy
Step-by-step explanation:
Equation 1 is
2x² - (1/3)ax + by - M = 0
M = 2x² - (ax/3) + by
Equation 2
3x²y - (1/3)xy³ + cy + B = 0
B = - 3x²y + (xy³/3) - cy

pen needs to be rectangular in shape however it will be built along a river side of the pen that does not need to be fenced. The farmer has a total of 700 feet of fence to build the pen. Determine the dimensions that will maximize area of the pen
Answer: The dimensions that will maximize area of the pen are 350 ft by 175 ft
Step-by-step explanation: The farmer has a total of 700 feet of fence for a rectangular pen which is in effect the perimeter. However, one side is by the river and would not need to be fenced. Hence we can determine that the perimeter would cover three sides only.
This means the sides would be in the ratio of 2 : 1 : 1
Hence, one side would be 2/4 and the other two sides would be 1/4 each
For the whole 700 meters of fencing, the sides can be calcualted as follows;
Length = 2/4 x 700
Length = 350
Width = 1/4 x 700
Width = 175
Therefore, with the length of fence available, the dimensions for the rectangular pen would be
Length = 350 ft
Width = 175 ft

Find the Center and Radius in the equation (x+3)2+(y+4)2=25
Answer:
(- 3, - 4 ) and r = 5
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + 3)² + (y + 4)² = 25 ← is in standard form
(x - (- 3))² + (y - (- 4))² = 5²
with centre = (- 3, - 4) and r = 5

Jack is a software salesman. His base salary is $1200, and he makes an
additional $50 for every copy of software he sells.
Let P represent his total pay (in dollars), and let N represent the number of
copies of software he sells.
a) Write an equation relating P to N.
b) Use the equation from part a to find his total pay if he sells 24 copies of
software.
Answer:
Step-by-step explanation:
a) Jack's additional income = N * 50 = $ 50N
P = 1200 + 50N
b) N = 24 copies
P = 1200 + 50*24
= 1200 + 1200
P = $ 2400

For the high school basketball game, it costs $8 for every 4 tickets.
Complete the table below showing the cost and the number of tickets.
Answer:
there is no graph
Step-by-step explanation:
$8 16 24 32 40 48 56 64 72 80
---------------------------------------------------------------------------
4 8 12 16 20 24 28 32 36 40
Final answer:
The question is about calculating the costs associated with purchasing tickets, given a known rate of $8 for every 4 tickets. Using the formula cost equals 2 times the number of tickets, one can calculate the total cost for any number of tickets, maintaining a direct proportionality.
Explanation:
Finding Costs Based on Ticket Quantities
To determine the cost for a varying number of tickets given the rate of $8 for every 4 tickets, we can set up a proportional relationship where the cost (C) is related to the number of tickets (T) by the constant of proportionality 8/4, or 2. Therefore, C = 2T, which means that the cost is simply twice the number of tickets because 8 dollars are charged for every 4 tickets.
We can fill out the table using the formula C = 2T, where C represents the total cost and T represents the number of tickets:
For 4 tickets: C = 2(4) = $8
For 8 tickets (twice the initial quantity): C = 2(8) = $16
And so on, for each additional set of 4 tickets, we add another $8 to the cost.
If we were to complete the hypothetical table, for each additional 4 tickets, we would add $8 to the total cost, maintaining this direct proportionality.

While solving an equation for x lewis is left with the equation 2=4. Explain why lewis can be certain that the equation does not have a solution
Answer: You do not have x alone on one side, therefore, you can be certain the equation has no solution!!
Step-by-step explanation: In order for the equation to have a solution it must look like this:
x= and some number
Final answer:
Lewis can be certain there is no solution to the equation because ending up with '2=4' is a contradiction, and two distinct constants cannot be equal.
Explanation:
When solving an equation, if you simplify all the expressions and end up with a statement such as 2=4, this indicates that the equation does not have a solution. This situation is also known as a contradiction because 2 and 4 are distinct constants and cannot be equal. A step-by-step approach might include starting from the original equation, performing algebraic manipulations, and then arriving at an absurd conclusion, which tells us the equation has no solution.
In contrast, when solving quadratic equations, such as x² = 4, you might get valid solutions like √4=±2, which indicate a solution set of {-2, 2}. However, if your result contradicts a fundamental truth, like the equality 2=4, it's clear that the equation has no feasible solution within the realm of real numbers.

Liu wants to decorate some cakes with shapes.
She has 140 shapes.
Each shape is a star or a heart.
The ratio of the number of stars : to hearts is 4:3.
She wants to put 5 stars and 4 hearts on each cake.
How many cakes can Liu decorate?
Show full working to support your answer.
Answer:
15 cakes can be decorated.
Step-by-step explanation:
Given:
Total number of shapes Liu has = 140
Ratio of shape of stars and hearts = 4 : 3
According to the question:
Each cake have 5 stars and 4 hearts.
Let the number of starts be "4x" and number of hearts be "3x" from the ratio.
Now,
⇒ [tex]4x+3x=140[/tex]
⇒ [tex]7x=140[/tex]
⇒ [tex]x=\frac{140}{7}[/tex]
⇒ [tex]x=20[/tex]
Number of stars = [tex]4x =4(20) =80[/tex]
Number of hearts = [tex]3x=3(20)=60[/tex]
Each cake have 5 stars and 4 hearts .
How many cakes can be decorated with 80 stars.
⇒ No.of cakes = Total number of stars / 5
⇒ [tex]C=\frac{80}{5}[/tex]
⇒ [tex]C=16[/tex]
How many cakes can be decorated with 60 hearts.
⇒ [tex]C=\frac{60}{4}[/tex]
⇒ [tex]C=15[/tex]
But both shapes are in combination so only 15 cakes can be decorated with the combination of 5 stars and 4 hearts.
Liu can decorate 15 cakes and only.
Final answer:
Liu can decorate 15 cakes with the 140 shapes she has, given the ratio of stars to hearts and the number of each she wants to put on each cake.
Explanation:
Liu wants to decorate cakes with a total of 140 shapes, where the ratio of the number of stars to hearts is 4:3. To find out how many shapes there are of each type, we first need to determine how many groups of 4 stars and 3 hearts are in 140 shapes.
Total ratio parts = 4 (stars) + 3 (hearts) = 7 parts.
Total groups of shapes = 140 shapes ÷ 7 parts per group = 20 groups.
So, there are 20 groups of stars and 20 groups of hearts. Now, we need to find out how many of each shape there are:
Stars = 20 groups × 4 stars/group = 80 stars
Hearts = 20 groups × 3 hearts/group = 60 hearts
Liu wants to put 5 stars and 4 hearts on each cake. The number of cakes she can decorate is limited by the shape she has the least of, which is the hearts. Now, let's calculate:
Cakes decorated with hearts = 60 hearts ÷ 4 hearts/cake = 15 cakes
Therefore, Liu can decorate 15 cakes with 5 stars and 4 hearts each, since the hearts will run out after 15 cakes.

For the triangle shown, describe which sides are the legs and which are the hypotenuse. Explain how you know.
Answer:
legs: a and b
hypotenuse: c
Step-by-step explanation:
The legs of a right triangle are the two sides that intersect to determine the right angle. The remaining side is called the hypotenuse.
Answer:
a and b are the legs, and c is the hypotenuse
Step-by-step explanation:
The legs of a right triangle are always the sides that form the right angle. Looking at the picture, we see that at one corner of the triangle, there's a little square. Remember that this little square always denotes an angle with degree 90, which means this is the right angle. Then, since sides a and b form this angle, we know that a and b are the legs.
Another thing to remember is that the hypotenuse of a right triangle is the side that lies opposite to the right angle. Here, you can see that side c lies opposite to the right angle, so we know it's the hypotenuse.
Hope this helps!
