Answer:
Step-by-step explanation:
Let x = number of hours to pull weed in a day
Let y = number of hours to now lawn in a day
It takes her an average of 3 hours to pull weeds and an average of 2.5 hours to mow the lawn. She can work no more than 8 hours a day.
This means
3x + 2.5y is lesser than/ equal to 8
She charges $50 to weed and $65 to mow the lawn.
This means she charges
50x +65y
She needs to cover her expenses of $120 to make a profit. This means she needs to earn an amount greater than or equal to $120
50x + 65y greater than or equal to 120
The circles in the figures form a series
The next step in the series is (B)
<h3>How to determine the next step?</h3>
From the figure, we have the following highlights
- The first circle has 2 segments
- The second circle has 4 segments
- The third circle has 5 segments
Using the above pattern, the next circle must have 6 segments
Hence, the next step in the series is (B)

Answer:
216 J
Step-by-step explanation:
The kinetic energy is given by ...
KE = 1/2mv^2
KE = (1/2)(3 kg)(12 m/s)^2 = 216 kg·m²/s² = 216 J
The kinetic energy of the toy is 216 joules.
__
Its potential energy depends on its height.
Answer:
We have a formula for division algorithm a= bq+r (1)
a is the greatest integer between the two given integers
And b is the other integer
q is the quotient
r is the remainder
here we have a=192 and b=7 substituting values in equation (1) we get
192 = 27 *7 + 3 (2)
now substitute quotient from equation (2) in place of a that is a=27 and remainder in place of b that is b =3 in equation as below
27= 9*3 +0
we will proceed till we get remainder zero.
