She can read 216 words per minute, because 72 times 1/3 is equal to 216.
There are several ways you can go about solving this. The easiest way is to graph it with desmos. But I'll show you how to do it algebraically.
So what it means when it says the point of intersection is what is the ordered pairs.
Well we can do this using substitution since that might be easier
So since y = 2 - 0.5x we can substitute it into x - 2y = 8
That gets us:
x - 2(2 - 0.5x) = 8
Next distribute the -2:
x -4 + x = 8
Combine like terms and solve for x!
2x = 12
x = 6
Now substitute x into any of our y = 2 - 0.5x so we get
y = 2 - 0.5(6)
y = -1
So our answer is (6,-1)
The side across from the right angle
The area of the sector in the circle can be calculated using the formula:
A = <span>π r</span>² θ / 360
where r is the radius and θ is the area subtended by sector. So,
A = π (10)² (37/360)
The answer is the first option.
Answer:
L = 62.5cm; B = 30cm
Step-by-step explanation:
P = 2 (L+W): L=25cm; W=12cm
=2 (25+12)
=50+24
P = 74cm
For a congruent rectangle with P = 185cm
A: 74 = 2 (25 + 12)
B: 185 = 2( ? + ?)
Since A/B are congruent;
185/75 = 2.5
B = 2 (2.5* (25 + 12)
= 2 ( 62.5 + 30)
= 125 + 60
= 185
Hence, B: L = 62.5cm; B = 30cm
185cm = 2 (62.5 + 30)
