A mechanic has two pieces of sandpaper of different sizes. Each piece is in the shape of a circle. The radius of the larger circle is 4 times the radius of the smaller circle. The area of the larger circle is how many times the area of the smaller circle?
Answer:
16 times
Step-by-step explanation:
difference in area = area of bigger circle / area of smaller circle
Area of a circle = πr²
r = radius
imagine the radius of the smaller circle = 1
Area of circle in terms of π= π
radius of the bigger circle = 4 x 1 = 4
Area of bigger circle in terms of π = π4² = 16 π
16 π / π = 16 times

PLEASE HELP I HAVE TEST!! Find the measure of the arc or angle indicated
Answer:
Step-by-step explanation:
<JKL = 90 ( being inscribed angle in semi circle )
< JKP = 38 ( Inscribed angles on same arc are equal )
So now
<PKL = <JKL - < JKP
= 90 - 38
= 52
FINALLY
ARC PL = 2 * < PKL (Relation between arc and inscribed angle )
ARC PL = 2 * 52
= 104
hope it helps :)
It costs $46 for 8 people to go ice skating how much will it be for 11 people to go show your work please
Answer:
It will cost 63.25
Step-by-step explanation:
We can use a ratio to solve
46 dollars x dollars
--------------- = ---------------
8 people 11 people
Using cross products
46 * 11 = 8x
506 = 8x
Divide each side by 8
506/8 =8x/8
63.25 =x
It will cost 63.25
Answer:
$63.25
Step-by-step explanation:
46/8 = $5.75 each
11 x 5.75 = $63.25

What is the equation of the line that passes through the point (4,-4) and has a
slope of -5/2
Answer:
y = -5/2x + 6
Step-by-step explanation:
y = -5/2x + b
-4 = -5/2(4) + b
-4 = -10 + b
6 = b
y = -5/2x + 6
IS IT A FUNCTION? PLEASE HELP ILL HIVE BRAINLEST! SHOW WORK ‼️‼️
1) (-5,-3)(7,2)(3,8)(5,-3) (3,-8)
Answer:
No, this is not a function. If you place the points, it will not pass the vertical line test. And, in a function, each x-coordinate has to have one y-coordinate. In this problem, there are two x-coordinates of 3, and they both have a different y-coordinate.

All you do is move all the terms not containing x to the right side of the inequailty form: x < 3
what is the answer at this
Answer:
A
Step-by-step explanation:
3x3x3 = 27
The number above the root symbol is the amount of time you have to multiply a number by itself. When we write the square root symbol the 2 is invisible, just like the 1 with a lone variable (x=1x).
In this case it is a cube root
PLZZZZZ HELPPP ILL GIVE BRAINLIEST
Answer:
340
Step-by-step explanation:
Answer:
100-60
Step-by-step explanation:
Used special calculater for this kind of problem.
find the length of x.
Answer:
3.5
Step-by-step explanation:
so this triangle is symmetrical by AA. so x would be symmetrical to 7, and 2.5 is symmetrical to 5.
[tex]\frac{x}{2.5}[/tex] = [tex]\frac{7}{5}[/tex]
x×5=5x
2.5×7=17.5
5x=17.5
x=17.5/5
x=3.5

Pythagrean Theorem is on C
A triangle is formed with side lengths of 7 inches, 24 inches, and 25 inches. Is the triangle a right triangle?
A
The triangle is a right triangle because 2(7)+2(24)=2(25) .
B
The triangle is a right triangle because 7^2+24^2=25^2 .
C
The triangle is not a right triangle because 25^2−24^2=7^2 .
D
The triangle is not a right triangle because 7^2+^25^2=24^2 .
Step-by-step explanation:
The traingle in Question B and A are right traingle because..If you use pythagoras theorem in those two questions,the sum of square of smaller two sides will be equal to the square larger side. Therefore they are rt.triangle. In D the case is opposite. As the sum of square of two smaller sides are comparatively more than larger sidei.e. hypotenuse. So it is not rt. triangle. This is your answer.

Ja’quan was told to go inside one afternoon while he was at summer camp. He heard thunder and saw flashes of lightning. Suddenly, small balls and chunks of ice were falling on the field. Ja’quan checked the thermometer, because he never saw ice fall in South Florida, and noticed that it was 77°F (or 25°C). How was ice able to fall even though the temperature was much warmer than freezing? a) Ja’quan read the thermometer wrong b) He must have observed hail falling from thunder clouds c) It was cold enough to allow solid precipitation to fall d) Children were most likely throwing ice Reasoning (explain your answer using science facts) _________________________________________ _______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Answer:
b
Step-by-step explanation:
hail can occur at temperatures not too cold and not too hot. since he checked his thermometer and it was warm, it is certainly possible that he saw hail

(2x+3x) x 3+15=12x+36
Answer:
Is this what you meant?
(2x + 3x) × (3 + 15) = 12x + 36
(5x) × (18) = 12x + 36
90x = 12x + 36
78x = 36
x = 36 / 78
x = 18 / 39
_____________________
or
3(2x+3x) + 15 = 12x + 36
10x + 15 = 12x + 36
-21 = 2x
2x = -21
x = -21/2
Mario was shopping for a new camera. He found one with an original price of $125.00 and is marked 45% off. Sale tax for the item is 5.2%. What is the final price of the camera, including tax?
Answer:
72.33
Step-by-step explanation:
45 percent of 125 is 56.25 so you subtract that from 125 and get 68.75 and then you do 5.2 percent of 68.75 and get 3.575 which rounds to 3.58 and you add that to 68.75 and get 72.33

What is the equation of the line that passes through point Q and is parallel to line P?
Answer:
[tex]y=\frac{3}{2} x+1[/tex]
Step-by-step explanation:
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Parallel lines always have the same slope (m) and different y-intercepts (b)1) Find the slope of line P
The slope of a line is equal to the [tex]\frac{rise}{run}[/tex], or the number of units the line moves up over the number of units the line moves to the right.
We can see that for line P, for every 2 units it moves to the right, it moves up 3 units.
Therefore, the slope of line P is [tex]\frac{3}{2}[/tex].
Knowing this, the equation of a line parallel to line P would have a slope of [tex]\frac{3}{2}[/tex] as well. Plug this into [tex]y=mx+b[/tex] as m:
[tex]y=\frac{3}{2} x+b[/tex]
2) Plug the given point Q into [tex]y=\frac{3}{2} x+b[/tex] to find the y-intercept (b)
[tex]y=\frac{3}{2} x+b[/tex]
Plug in point Q (2,4)
[tex]4=\frac{3}{2} (2)+b\\4=\frac{6}{2}+b\\4=3+b[/tex]
Subtract 3 from both sides
[tex]4-3=3+b-3\\1=b[/tex]
Therefore, the y-intercept of this line (b) is 1. Plug this back into our original equation:
[tex]y=\frac{3}{2} x+b[/tex]
[tex]y=\frac{3}{2} x+1[/tex]
I hope this helps!
