Answer:
4[tex]\pi[/tex]
Step-by-step explanation:
A = [tex]\pi[/tex][tex]r^{2}[/tex]
A = 4[tex]\pi[/tex] [tex]cm^{2}[/tex]
4[tex]\pi[/tex] =
4 = [tex]r^{2}[/tex]
2 = r
C = 2[tex]\pi[/tex]r
C = 2(2)[tex]\pi[/tex]
C = 4[tex]\pi[/tex]
Pencils cost $.10 and erasers cost $0.25. steve bought 5 more pencils than erasers. he spent a total of $1.55. how many erasers did steve buy?
Answer:
Let x be the number of pencils Steve bought.
Let y be the number of erasers Steve bought.
x=y+5
0.1x + 0.25y = 1.55
Solving the system, our answer is: (8, 3)
So, she bought 3 erasers.

When y=48, x=4.2. If the value of y varies directly with x, what is the value of y when the value of x is 10.6?
Answer:
y = 121.14
Step-by-step explanation:
For this, we will need to start by cross multiplying.
(4.2 * y) = (48 * 10.6)
4.2y = 508.8
to isolate the varible, we need to divide both sides by 4.2
y = 121.14
Use the Triangle Inequality Property to determine whether a triangle can be formed with the given side lengths. 4 m, 8 m, 9 m *
Answer:
Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene, isosceles, equilateral and so on.
The triangle inequality property states that the sum of any two sides of a triangle must be greater than the third side. If a, b and c are the sides of a triangle then:
a + b > c; a + c > b; b + c > a
Given a triangle with side length 4 m, 8 m, 9 m:
4m + 8m = 12m > 9m
4m + 9m = 13m > 8m
8m + 9m = 17m > 4m
Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m.

if the simple interest on 2000 for 4 years is 4000 then what is the interest rate
Answer:
Principal = Rs 2000
Time = 4 years
Interest = Rs 400
Now, Interest= Principal×Rate×Time/100
400= 2000×R×4/100
R= 400×100/2000×4

Which of the following is the product of the rational expressions shown
below?
2/x • 3/2x - 5
Answer:
Step-by-step explanation:
6/ 2x2-5x
The product of the rational expression 2/x(3/2 x-5) is 3-10/x.
What is expression?Expression is combination of numbers, fraction, symbols , coefficients, indeterminants or determinants. It shows a relationship between variables. It is mostly not found in equal to form.
How to find product?We have been given an expression 2/x(3/2 x-5) and we have to find the product of the expressions.
Product=2/x*3/2 x-2/x*5
To find the product of the expression, we have to multiply numerators with numerators and denominators with denominators and then perform the division part.
=6x/2x-10/x
=3-10/x
Hence the product of the rational expression 2/x(3/2 x-5) is 3-10/x.

what is pi and how invented it??
Answer:
Step-by-step explanation:
The Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for π. The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
Answer:
π is a mathematical constant. Its commonly used value is 3.14. There is a expanded value for π. It appears in many formulas in all areas of mathematics and physics. In maths, it is commonly used for solving of circles and spheres.
The π was invented by Archimedes of Syracuse. He was one of the greatest mathematicians of the ancient world.

A fruit seller brought 120 oranges for rs 500 and spent rs 60 for parking them into 10 boxes each containing a dozen oranges. If he sold a dozen of oranges for rs 58.8, find the profit percentage I know the answer it is 5% but I need the explanation for it in picture format it is also ok but in neat handwriting pls help
Answer:
First, we know that he spent rs500 plus rs60 in the whole process, then the total cost is:
C = rs500 + rs60 = rs560
Now he sells the oranges in packs of 12, then if he has 120 oranges, the total number of packs that he can sell is:
120/12 = 10
So he has 10 packs of 12 oranges.
And he sells each one for rs58.8
Then if he sells the 10 packs, the total revenue is:
R = 10*(rs58.8) = rs588
The profit is the difference between the revenue and the cost, here the profit is:
P = R - C = rs588 - rs560 = rs28
And the profit percentage is calculated as follows:
(P/C)*100%
Where P = profit and C = cost, then we have:
(rs28/rs560)*100% = 5%

how do you know when the square root of a positive integer is simplified
Answer: Simplifying a square root just means factoring out any perfect squares from the radicand, moving them to the left of the radical symbol, and leaving the other factor inside the radical symbol.

A central angle 0, in a circle of radius 4 ft intercepts an arc length of 50 ft.
Calculate the radian measure of 0.
Given:
The central angle = [tex]\theta[/tex]
Radius of the circle = 4 ft
Intercepted arc length = 50ft
To find:
The value of [tex]\theta [/tex] in radian measure.
Solution:
The formula for arc length is
[tex]s=r\theta[/tex]
where, r is radius and [tex]\theta [/tex] is the central angle in radians.
Putting s=50 and r=4, we get
[tex]50=4\theta[/tex]
Divide both sides by 4.
[tex]\dfrac{50}{4}=\theta[/tex]
[tex]12.5=\theta[/tex]
Therefore, the value of [tex]\theta [/tex] is 12.5 radians.

Answer:
the plane flies 396,000yd in 30 min
Step-by-step explanation:
450 / 2 = 225
1 mile = 1,760

Plz mark as brainliest if this helped! Have a nice day!!!
-Lil_G
Step-by-step explanation:
450 miles = 1hour = 60mins
X miles = 30mins
cross multiply
450 × 30 = 60 × X
13500 = 60X
divide through by 60
225 = X
therefore, X = 225miles
now
1 mile= 1760 yards
225 miles = X
cross multiply
X = 1760 ×225
X = 396000 yards
