Answer:
You can buy 6 buckets
Step-by-step explanation:
30=-12+3x
-12. -12
18=3x
divide by 3
you can buy 6 buckets
The answer is c. Because 4.5 * 2 is 9 then you add 0.5 so the answer is 9.5
Remark
This is a very interesting question. Draw a line from the origin to where the upper right vertex of the square touches the line. That line has the property that the its equation is y = x. So the "solution" to the point of intersection is the solution of the two equations.
y = x (1)
3x + 4y = 12 (2)
Put x in for y in equation 2
3x + 4x = 12
7x = 12
x = 12/7
x = 1.714
y = 1.714
Problem A
<em><u>x intercept</u></em>
The x intercept occurs when y = 0
3x + 4(0) = 12
3x = 12 Divide by 3
x = 12/3
x = 4
the x intercept = (4,0)
<em><u>y intercept</u></em>
The y intercept occurs when x =0
3(0) + 4y = 12
4y = 12
y = 12/4
y = 3
y intercept = (0,3)
Problem B
x and y both equal 1.714 so they are also the length of the square's side.
Problem C
See solution above. x =y is the key fact.
x = y = 1.714
Left side is 22.
22 x 10 = 220
(20 - 6) x 12 = 168
6 x 20 = 120
220 + 168 + 120 = 508
Thank you very much.
The minute hand when moving is swiping a sector
The arc length is given 23.5 inch the angle swiped is 52 degree
we have to find radius
length of arc = 2pi r( theta )/360
23.5 = 2* 3.14 * r ( 52/360)
23.5 = r(0.907)
r= 23.5/ 0.907
r=25.90 inches Answer
