Answer:
The cost of the one word is $30 .
Option (b) i.e is used to determine the total number of words in the ad mr.grant placed.
Step-by-step explanation:
Let us assume that the number of words in the ad be x.
As given
Mr.grant spent $8.40 to place an ad in the newspaper.
This price included one time fee of $6.00 plus $0.08 per word.
Than the equation becomes
8.40 = 6 .00 + 0.08x
Simplify the above
8.4 = 6 + 0.08x
8.4 - 6 = 0.08x
x = $30
Therefore the cost of the one word is $30 .
Option (b) i.e is used to determine the total number of words in the ad mr.grant placed.
Answer:
He reached the top of the tree on the 31st day
Step-by-step explanation:
The total distance for the owl to climb is 93 units.
If the owl climbed 18 units up the tree every day without coming down, the owl would have taken 93/18 days to reach the top of the tree.
However, the owl descends by 15 units every night. This just reduces the overall distance covered at the end of each day's climb.
The net distance covered by the owl after each day is 18-15 units = 3 units of climb. This is the steady distance the owl gains up the three at the end of each day after the ascent and descent.
The time taken for the climb moving at this pace of 3 units per day will be
93 units / 3 units per day = 31 days
Answer:
The multiplicative Inverse of any number except zero, is 1 over the number
Step-by-step explanation:
X + 3y = 7
x = -3y + 7
2x + 4y = 8
2(-3y + 7) + 4y = 8
-6y + 14 + 4y = 8
-6y + 4y = 8 - 14
-2y = - 6
y = -6/-2
y = 3
x + 3y = 7
x + 3(3) = 7
x + 9 = 7
x = 7 - 9
x = -2
solution is (-2,3)
Answer:
Step-by-step explanation:
The arc length is determined by the formula , where s is the arc length, r is the radius, and is the value of the central angle (in radian formatting).
By substituting the values for the radius and the central angle, you can solve for the arc length.
.
The central angle is converted to radian form by multiplying the angle in degrees by the fraction of π/180 - 360° * π/180 = 360π/180 = 2π.
Now, substitute the values and solve for s.
s = (2)(2π)
