what is the area of a 3 and a quarter inch circle?
Answer:
33.2in²Step-by-step explanation:
to find area we have to find redious first sor=d/2therefore
[tex]r = \frac{3 \frac{1}{4} }{2} [/tex]
[tex]r = \frac{ \frac{13}{2} }{2} [/tex]
[tex]r = \frac{13}{2} \div 2[/tex]
[tex]r = \frac{13}{4} [/tex]
[tex]area \: of \: a \: circle \: = \pi {r}^{2} [/tex]
[tex] = \pi (\frac{13}{4} ) ^{2} i {n}^{2} [/tex]
[tex] = \pi \times \frac{169}{16} {in}^{2} [/tex]
[tex] = \frac{169\pi}{16} i {n}^{2} [/tex]
[tex] = 33.2 \: i {n}^{2} [/tex]
n+5/-3=2
To solve this equation for n the first step is to multiply by −3 on both sides. Why is the first step multiplication and NOT addition? (one sentence response)
Answer:
The first step is multiplication because 5/-3 is a fraction and to make the equation more easier to solve for n, multiplying by -3 will get rid of the fraction.

Write your answer using a percent sign (%).
Answer:
50%
Step-by-step explanation:
45 is half of 90. A percent is out of 100. So when you split 100 in half, it equals 50. The answer is 50%. Glad I could help!
Answer:
50% of the students voted for the athlete.

Answer:
x = 20y = 10Step-by-step explanation:
The angle marks show that ΔRST is isosceles, so RT = RS. They also show ΔRTU to be equilateral, so UT = RT.
UT = RS
x -5 = 15
x = 20 . . . . . . add 5

ΔRTU is equilateral, so ∠RTU is 60°. The angle marked 3y° is complementary to that.

Energy and mass are related by the formula
E = mc².
m is the mass of the object
c is the speed of light
Solve the equation for the mass of the object, m.
Answer:
m=E/c².
Step-by-step explanation:
Transposing the formula
E=mc²
we divide both sides by c² then cancel out where necessary so m would stand alone
E/c²=mc²/c²
cancelling c² on the right hand side, equation becomes
m= E/c²

MOTIVATION
Most geometry so far has involved triangles and quadrilaterals, which are formed by intervals on lines, and we turn now to the geometry of circles. Lines and circles are the most elementary figures of geometry − a line is the locus of a point moving in a constant direction, and a circle is the locus of a point moving at a constant distance from some fixed point − and all our constructions are done by drawing lines with a straight edge and circles with compasses. Tangents are introduced in this module, and later tangents become the basis of differentiation in calculus.
The theorems of circle geometry are not intuitively obvious to the student, in fact most people are quite surprised by the results when they first see them. They clearly need to be proven carefully, and the cleverness of the methods of proof developed in earlier modules is clearly displayed in this module. The logic becomes more involved − division into cases is often required, and results from different parts of previous geometry modules are often brought together within the one proof. Students traditionally learn a greater respect and appreciation of the methods of mathematics from their study of this imaginative geometric material.
The theoretical importance of circles is reflected in the amazing number and variety of situations in science where circles are used to model physical phenomena. Circles are the first approximation to the orbits of planets and of their moons, to the movement of electrons in an atom, to the motion of a vehicle around a curve in the road, and to the shapes of cyclones and galaxies. Spheres and cylinders are the first approximation of the shape of planets and stars, of the trunks of trees, of an exploding fireball, and of a drop of water, and of manufactured objects such as wires, pipes, ball-bearings, balloons, pies and wheels.
a) The series of transformations to map Circle A onto Circle B is likely a translation. b) The series of transformations to map Circle C onto Circle A is a translation, rotation, and scaling.
a. To map Circle A onto Circle B, we must determine the transformation sequence. We can scale, rotate, and translate.
Translation: An object is translated horizontally or vertically without affecting shape or orientation. To match Circle B, Circle A appears to need to be shifted right and up.
Rotation: An object rotates around a fixed point. Rotation may not be needed since Circle A and Circle B appear to be aligned.
Scaling: An object is resized by scaling. Since Circle A and Circle B are the same size, scaling doesn't seem necessary.
Thus, Circle A-to-Circle B transformations are likely translations.
b. Again, we must determine the transformation sequence to transfer Circle C onto Circle A. Translation: Based on their relative positions, Circle C needs to be shifted left and down to match Circle A.
Rotation: To align Circles A and C, they must be rotated.
Scaling: Circle A is larger than Circle C, hence Circle C should be scaled down.
Thus, translating, rotating, and scaling map Circle C onto Circle A.

73 divided by the difference between 12 and 7
Answer:
14.6
Step-by-step explanation:
difference: 12-7=5
division: 73/5=14.6
The 73 divided by the difference between 12 and 7 is equal to 14.6.
To properly calculate 73 divided by the difference between 12 and 7, we follow these steps:
Calculate the difference between 12 and 7:
12 - 7 = 5
Divide 73 by the difference obtained:
73 ÷ 5 = 14.6
Therefore, 73 divided by the difference between 12 and 7 is equal to 14.6. This means that if we take the value 73 and divide it by the difference between 12 and 7, the quotient will be 14.6. The difference between 12 and 7 is 5, and when we divide 73 by 5, we obtain 14.6. It is important to note that the result is a decimal value, specifically 14.6.

s=t+ 5 45 + 2t = 110
The amount of ribbon needed for a square poster will be 20.
And, The amount of ribbon needed for a triangular poster will be 15.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The system of equation are;
⇒ s = t + 5
⇒ 45 + 2t = 110
Now,
Since, The system of equation are;
⇒ s = t + 5 ..(i)
⇒ 4s + 2t = 110 ..(ii)
Solve equation (ii) for t as;
⇒ 45 + 2t = 110
⇒ 4s + 2t - 4s = 110 - 4s
⇒ 2t = 110 - 4s
⇒ t = 55 - 2s
Substitute above value in equation (i), we get;
⇒ s = t + 5
⇒ s = 55 - 2s + 5
⇒ s + 2s = 60
⇒ 3s = 60
⇒ s = 20
And, ⇒ t = 55 - 2s
⇒ t = 55 - 2 x 20
⇒ t = 55 - 40
⇒ t = 15
Thus, The amount of ribbon needed for a square poster will be 20.
And, The amount of ribbon needed for a triangular poster will be 15.
