Answer:
Choice 3
Step-by-step explanation:
The reading rate of Sam is 0.75 pages/minute.
i.e 30 pages/40 minutes
The reading rate of Bill is 0.5 pages/minute
The reading rate of Francine is 0.72 pages/minute
The reading rate of Leroy is 0.75 pages/minute which is the same as Sam's.
Answer:
a = 4
Step-by-step explanation:
y = 2x + 1 ......(1)
Going through y - y1 = m(x - x1)
m is slope and it is 2
y1 = 9 and x1 = a
y - 9 = 2(x - a)
y - 9 = 2x - 2a
y = 2x - 2a + 9 ........(2)
Equating (1) and (2)
2x + 1 = 2x - 2a + 9
Collecting like terms
2x - 2x + 2a = 9 - 1
2a = 8
a = 8/2
a = 4
Answer:
The other dimension of the sandbox must be (4x+3).
Hope this helps! Have a good day!
Equation of a circle is:
<span>(x−h<span>)2</span>+(y−k<span>)2</span>=<span>r2</span></span>
h is the x-coordinate of the center and k is the y-coordinate of the center. Even though the formula has minus signs, those are positive numbers. If there were plus signs in there, the numbers h and k would actually be negative. Now since you're centered at the origin, that means h and k are 0, so you'd just have this:
<span><span>x2</span>+<span>y2</span>=<span>r2</span></span><span>
Now since your radius is 7, just square it and replace r^2 woth that value :)</span>
Answer:
12.68
Step-by-step explanation:
76 degrees /2 = 38
Half the width of 15m forms the lower side of the triangle: 7.5 m
sin(38) = 7.5/h
=12.1820
12.18+.5
12.68
