Let the length be l
Then,
l *(l-3)= 88
l²-3l =88
l²-3l-88=0
l²-11l +8l -88 =0
l(l-11) + 8(l-11) =0
(l+8)(l-11)=0
As, l can't be negative, length=11cm and width=(l-3)=11-3 =8 cm
The answer is B. It is shifted up by 6*1.5-2-2 with is 9-2-2=5.
Answer:
Step-by-step explanation:
As C and D are both at y = -9, the line below V₂ is vertical and located at
x = ½(22 + (-2) = 10
The line between V₁ and V₂ will contain the point halfway between B and D.
x = ½(14 + (-2)) = 6
y = ½(7 + (-9)) = -1
(6, -1)
The slope of the line between V₁ and V₂ is the same as between V₁ and our just found midpoint between B and D
m = (5 - (-1)) / (0 - 6) = -1
so the line equation is
y = -x + 5
Which intersects x = 10 at
y = -10 + 5 = -5
V₂ = (10, -5)
The distance between V₂ and B, C, and D is
d = √((14 - 10)² + (7 - (-5))²) = √160
The distance between V₁ and B, A, and D is
d = √((-10 - 0)² + (15 - 5)²) = √200
As √200 > √160, the dump should be located at V₁ or at least √200 away from any two of the points
BEST estimate of this amount is
. Correct option A. 2 x 10^7 .
<u>Step-by-step explanation:</u>
Here we have , Hoover Dam spans the Colorado River on the Nevada-Arizona state line. For its construction, the federal government purchased 21,670,000 pounds of gates and valves. We need to find BEST estimate of this amount . Let's find out:
21,670,000 pounds
⇒ 21,670,000 pounds
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Now, Rounding of 2.167 we get 2 ,So
⇒ 
Hence , BEST estimate of this amount is
. Correct option A. 2 x 10^7 .
Answer:
x = 92
Step-by-step explanation:
The segment of measure 46 joins the midpoints of 2 sides of the triangle and is one half the measure of the third side, thus
x = 2 × 46 = 92
