There is no whole number that is half of 11 but the half number is 5.5
Finding two geometric means between 10 and 125:
a 1 = 10, a 4 = 1250
a 4 = a 1 * q^3
1250 = 10 * q^3
q^3 = 1250 : 10
q^3 = 125
q = 5
a 2 = 10 * 5 = 50
a 3 = 10 * 5² = 10 * 25 = 250
Answer: The two geometric means are: 50 and 250, since 10, 50, 250 , 1250 forms a geometric sequence.
Answer: B & D
Step-by-step explanation:
In this scenario we want to come out with a situation where both sides are in an even playing field, as the equation solves to zero.
If a diver is 35 feet below water (-35) and he comes up to breathe, he goes up 35ft (35) meaning he is at the surface (0).
If Manuel is in debt for 35$ (-35) and then he pays off the 35$ (+35) then he is even (at 0).
If the speed is 26.33 miles per day. Then the number of miles you traveled on the 4 days will be 105.33 miles.
<h3>What is speed?</h3>
The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
The route to an ancient pyramid is 79 miles long.
If you traveled the same amount of time for 3 days.
Then the speed will be
S = 79 / 3
S = 26.33 miles per day
Then the number of miles you traveled on the 4 day will be
26.33 = D / 4
D = 105.33 miles

Answer:
42 + 2n ≥ 80
Step-by-step explanation:
Given,
Naomi's earnings for one day = $ 42,
Also, she earns extra $2 for each CD she sells,
Thus, the extra earning for n CDs = 2n dollars,
So, her total earning for a day if she sells n CDs = ( 42 + 2n ) dollars,
If Naomi wants to earn at least $80 per day,
Her total earning ≥ 80 dollars,
⇒ 42 + 2n ≥ 80
Which is the required inequality.
