Answer:
120√6
Step-by-step explanation:
Simplify the 5√8 to 2√2
simplify the √18 to 3√2
so it would be √3 * 2√2 * 5 * 2√2 * 3√2
when a square root of an expression is multiplied by itself:
√3 * 2 * 2* 5 * 2 * 3√2
so as we calculate it, 2 * 2* 5 * 2 * 3 = 120 and √2 * √3 = 6
we know that
so
1) the expression is equal in numbers to
2) the expression is equal in numbers to
therefore
and have the same value
seconds. What is its unit rate of speed?
Answer:
The speed at which the satellite travel is 6.80 miles per second
Step-by-step explanation:
Given as :
The distance cover by satellites = 29 miles
Or, The distance cover by satellites = miles
The Time taken by satellite to travel with this speed = 4 sec
Or, The Time taken by satellite to travel with this speed = seconds
Let the Speed with which the satellite travel = s miles per second
Now, As we know
Speed =
Or, s =
or, s =
∴ s = 6.80 mps
So, speed = s = 6.80 miles per second
Hence The speed at which the satellite travel is 6.80 miles per second Anwser
Answer:
The kids is 5.50 adult is 7..50
Step-by-step explanation:
we create an equation
2x + 3y =31.50
and
1x + 5y=35.00
1x is just x so we subtract 5y from both sides
x= 35.00-5y
fill x with 35.00-5y
2(35.00 - 5y) + 3y = 31.50
70.00 - 10y +3y = 31.50
-10y + 3y = -38.50
-7y=-38.50
-7y/-7= -38.50/-7
y=5.50
