Answer:
W = 69.5 L = 109.5
Step-by-step explanation:
L = 3W-99
Perimeter = 2L + 2W
358 = 2(3W-99) + 2W
358 = 6W-198 + 2W
358 = 8W-198
556 = 8W
69.5 = W
- 358 = 2L+2W
- 358 = 2L + 2(69.5)
- 358 = 2L + 139
- 219 = 2L
- L = 109.5
First you find the square root of 16, which is 4. Then multiply 4 by 20, which is 80. Therefore, your answer is 80.
Answer:
see explanation
Step-by-step explanation:
given a parabola in standard form : y = ax² + bx + c : a ≠ 0
• If a > 0 then parabola opens up
• If a < 0 then parabola opens down
given y = 4x² - 8x + 8 ← in standard form
with a = 4, b = - 8 and c = 8
here a > 0 then parabola opens up
Answer:
B. 8sqrt(2)
Step-by-step explanation:
The legs of an isosceles right triangle are congruent and measure 45 deg. The right angle measures 90 deg. The ratio of the lengths of the sides of a 45-45-90 deg triangle is 1 : 1 : sqrt(2).
Since the hypotenuse measures 8, then the legs measure 8/sqrt(2)
8/sqrt(2) * sqrt(2)/sqrt(2) = 8sqrt(2)/2 = 4sqrt(2)
Answer: B. 8sqrt(2)
3/14 = 1 day
___ = 5 days
Multiply 3/14 by 5:
3/14 * 5 = 15/14
The answer is A.
