Answer:
Building A is 660 feet and Building B is 830 feet
Step-by-step explanation:
Let x represent the height of building B.
Since building A is 170 feet shorter than building B, it can be represented by x - 170.
Create an equation and solve for x:
(x) + (x - 170) = 1490
2x - 170 = 1490
2x = 1660
x = 830
So, the height of building B is 830 feet.
Subtract 170 from this to find the height of building A:
830 - 170
= 660
Building A is 660 feet and Building B is 830 feet
The answer is 45 total.
So Tommy is 22 years old while his Father is 45.
45 years of age total, tommy is 23 years younger so 45 - 23 = 22 so tommy is 22 while his father is 45.
Vertex=(0,0)
directrix is x=2.5
or x-2.5=0
so focus S is (-2.5,0)
let P(x,y)be any point on the parabola.
Let M be the foot of perpendicular from P(x,y) on the directrix.
then SP=PM
<h3>The length of rectangle is 12x³ metres .</h3>
As we know that
♦ Area of rectangle = Length × breadth
Substituting known values ,
⇒ 144x⁴ = 12x ( Length )
⇒ 144x⁴ / 12x = Length
⇒ 12x³ = Length
⇒ Length = 12 x³
So, when solving this: you’ll want to consider multiples of 7 and 4.
7,14,21,28
4,8,12,16,20,24,28
If you write four +7’s and seven -4’s, they cancel out. Given that that is 11 digits, do it twice and you have your answer.
Eight +7’s
Fourteen -4’s
