Distance traveled by Robert = 292 miles
Time taken by Robert to cover this distance = 4 hours.
Now converting miles in feet.
1 mile = 5280 feet
so, 292 feet = 292 * 5280 = 1541760 feet
Now converting 4 hours in seconds.
1 hour = 3600 seconds
so, 4 hours have 3600 * 4 = 14400 seconds.
Now the question says, we have to find the speed in feet per second

equals,

= 107.067 feet per second
-3(y+2)^2-5+6y
-3(y^2+4y+4)-5+6y
-3y^2-12y-12-5+6y
-3y^2-6y-17
First, we are going to find the sum of their age. To do that we are going to add the age of Eli, the age Freda, and the age of <span>Geoff:
</span>

The combined age of Eli, Freda, and Geoff is 40, so the denominator of each ratio will be 40.
Next, we are going to multiply the ratio between the age of the person and their combined age by <span>£800:
For Eli: </span>
For Freda:
For Geoff: 
<span>
We can conclude that
Eli will get </span>
£180,
Freda will get £260, and
Geoff will get <span>
£360.</span>
Answer:
<h2>√512 by √512 </h2>
Step-by-step explanation:
Length the length and breadth of the rectangle be x and y.
Area of the rectangle A = Length * breadth
Perimeter P = 2(Length + Breadth)
A = xy and P = 2(x+y)
If the area of the rectangle is 512m², then 512 = xy
x = 512/y
Substituting x = 512/y into the formula for calculating the perimeter;
P = 2(512/y + y)
P = 1024/y + 2y
To get the value of y, we will set dP/dy to zero and solve.
dP/dy = -1024y⁻² + 2
-1024y⁻² + 2 = 0
-1024y⁻² = -2
512y⁻² = 1
y⁻² = 1/512
1/y² = 1/512
y² = 512
y = √512 m
On testing for minimum, we must know that the perimeter is at the minimum when y = √512
From xy = 512
x(√512) = 512
x = 512/√512
On rationalizing, x = 512/√512 * √512 /√512
x = 512√512 /512
x = √512 m
Hence, the dimensions of a rectangle is √512 m by √512 m
Answer:
The value of the 3 is 30,000,000.
Step-by-step explanation:
From the digit at the right, you go multiplying each element by 10 powered to a counter that starts at zero and increases at every digit. So:
Our counter is i
i = 0;
v(7) is the value of the 7

i = 1;
v(5) is the value of the 5

i = 2;
v(1) is the value of the 1

i = 3;
v(5) is the value of the 5

i = 4;
v(9) is the value of the 9

i = 5;
v(6) is the value of the 6

i = 6;
v(8) is the value of the 8

i = 7;
v(3) is the value of the 3

The value of the 3 is 30,000,000.
