help me out please <3
ANSWER is Option C
Use 2πr = 2×3.14×6 = 37.68 inches
Formula for the circumference of a circle: C = pi * Diameter
We are given the diameter, 12 inches, so all we have to do is plug in our values.
C = 3.14 * 12
C = 37.68 inches

solve the inequality 28<6x-2
Answer:
5 < x
Step-by-step explanation:
28<6x-2
Add 2 to each side
28+2<6x-2+2
30 < 6x
Divide each side by 6
30/6 < 6x/6
5 < x
Answer:
5 < x OR x > 5
same thing just reversed
Step-by-step explanation:
28 < 6x - 2
28+2 < 6x (- 2 + 2)
30 < 6x
30/6 < 6x/6
5 < x
If 5 + b = 3 and a - b = 7 , then which of the following is true?
2a + b = 8
2a - 2b - 12
a - 2b = 11
2(a - b) = 6
2a plus 6 equl eight i hink so
Answer:
Solve the given system first
5 + b = 3a - b = 7Find b:
b = 3 - 5 = -2Find a:
a - (-2) = 7a = 7 - 1a = 5Verify the options for correctness:
2a + b = 2(5) + (-2) = 10 - 2 = 8, correct2a - 2b = 2(5) - 2(-2) = 10 + 4 = 14, incorrecta - 2b = 5 - 2(-2) = 5 + 4 = 9, incorrect2(a - b) = 2(5 - (-2)) = 2(7) = 14, incorrectLucas writes a numerical expression that has a value of 37. Which of the following expressions did Lucas write?
Answer:
a) 2.5^2+19\times2.5-16.75
Step-by-step explanation:

How do you find the area of a cone?
Surface area of cone = πr(r+√(h2+r2))
where r is the radius of the circular base
h is the height of coneOr
Surface area of cone =πr(r+L)
where L is the slant height of the cone
Answer:
The formula for the area of a cone is 3.14 times the radius times the side

Help please I don't understand.
===========================================================
Explanation:
If XY is tangent to the circle, then the radius ZX would be perpendicular to the tangent XY. In other words, the angle YXZ would be 90 degrees.
Furthermore, it means triangle WXY would be a right triangle.
Effectively, we need to find out if triangle WXY is a right triangle.
Recall that we can use the converse of the pythagorean theorem to find out if a triangle is a right triangle or not.
We have these side lengths of the triangle:
XY = 9.6WX = WZ+ZW = 6.4+6.4 = 12.8YW = 16Let's say a = 9.6, b = 12.8 and c = 16
The order of 'a' and b doesn't matter. All that matters is that c is the longest side.
Plug those values into the pythagorean theorem and simplify each side.
a^2+b^2 = c^2
(9.6)^2 + (12.8)^2 = (16)^2
92.16 + 163.84 = 256
256 = 256
We end up with a true equation, so the first equation is true for those a,b,c values. Hence, we have shown that the triangle is a right triangle, and this concludes that XY is indeed tangent to the circle.

Find the co-ordinates of a point which divides the line joining the points (-3, 9) and (1, -3) internally in the ratio of 3:1. *
a) (1, 1)
b) (0, 0)
c) (1, 2)
d) (2, 2)
The co-ordinates of a point which divides the line joining the points (-3, 9) and (1, -3) internally in the ratio of 3:1 is , (0,0)
What is a line?The equation of a line is a relationship between x and y coordinates.
Section formula for a point which divides line joining points into m:n ratio,
(X,Y) = { (mx₂+nx₁)/m+n , (my₂+ny₁)/m+n }
Given points,
(-3, 9) and (1, -3)
m:n = 3:1
(X,Y) = { (3×1+ 1×-3)/3+1 , (3×-3 + 1×9 )/ 3+1 )
(X,Y) = (0,0)
Hence, the points will be, (0,0)

Dos calles tienen las siguientes longitudes 2 2/5 y 1 3/4 de kilometro cual es la longitud total de ambas
Answer:
La longitud total de ambas calles es [tex]3\frac{23}{20}[/tex]
Step-by-step explanation:
Dos calles tienen las siguientes longitudes: [tex]2\frac{2}{5}[/tex] y [tex]1\frac{3}{4}[/tex] de kilometro. Para calcular la longitud total de ambas calles debes sumar ambas longitudes:
[tex]2\frac{2}{5}+1\frac{3}{4}[/tex]
Para sumar fracciones mixtas, en primer lugar sumas la parte entera:
2+1= 3
Luego se deben sumar las fracciones. Para ello, es necesario encontrar el común denominador. En este caso el común denominador entre 5 y 4 es 20.
Ahora debemos amplificar las fracciones al común denominador. Esto es, se divide por el denominador de cada fracción y el resultado se multiplica por el numerador de la fracción:
[tex]\frac{2}{5}+\frac{3}{4}=\frac{8+15}{20} =\frac{23}{20}[/tex]
Entonces el resultado de la suma es:
[tex]3\frac{23}{20}[/tex]
La longitud total de ambas calles es [tex]3\frac{23}{20}[/tex]
