Answer:
1.12 × 10^-3
Step-by-step explanation:
The computation of the width of the photograph is as follows:
As we know that
Area of the rectangle = length × width
33 ÷ 20 square inches = 1475 inches × width
So, the width is
= Length ÷ area
= 1475 inches ÷ (33 ÷ 20 square inches)
= 1.12 × 10^-3
Answer:
x is equal to 6
Step-by-step explanation:
in a circle the perpendicular from centre to any chord bisects the chord into 2 equal parts.
Answer:
138 is closest to the Lateral surface which is 113.097
Step-by-step explanation:
Okay, Tommy runs in a positive y direction at 3mph, and his position can be expressed as:
T=3t
Then Zach starts running two hours later at 4mph and his position can be expressed as:
Z=4(t-2)=4t-8
The distance between Tommy and Zach can be expressed as the hypotenuse length of a right triangle with the distances for Tommy and Zach being the lengths of the sides...
d^2=T^2+Z^2
d^2=(3t)^2+(4t-8)^2
d^2=9t^2+16t^2-64t+64
d^2=25t^2-64t+64, and we want to know when they are 8 miles apart
25t^2-64t+64=8^2
25t^2-64t+64=64
25t^2-64t=0
25t(t-2.56)=0
So 2.56 hours after Tommy started running they will be 8 miles apart.
To be clear though, this is the time Tommy spent running, or the time that elapsed since Tommy started running. Zach has only been running for 0.56 hours. So if they are looking for the time Zach ran it is 0.56 not 2.56 hours.
Step-by-step explanation:
here's what you need to do solve all of those problems and see if it's correct and then whichever one is correct is the one that equals X
