From the calculation below, the number of days it will take region d to catch up with region c is 8 days.
<h3>How do we calculate the number of days from the word problem?</h3>
The number of days it will take region d to catch up with region c can be calculated using the following formula:
c = d + 50y ................... (1)
c = the number of boxes sold by region c = 1,800
d = the number of boxes sold by region d = 1,400
y = number of days it will take region d to catch up = ?
Substituting the relevant values into equation (1) and solving for y, we have:
1,800 = 1,400 + 50y
1,800 - 1,400 = 50y
400 = 50y
y = 400 / 50 = 8

11 and 33 are the numbers.
Answer:
x=-2
Step-by-step explanation:
first, you substitute y=0, then you solve the equation for x
y=x+2
0=x+2
x=-2
Q 16. The energy is 308.7 J.
Q 17. The energy is 896000 J.
Step-by-step explanation:
Q 16. Given,
Mass (m) of the carriage and baby = 1.5 kg
Height (h) = 21 m
To find the energy.
We will find the potential energy as it rests at the top.
Formula
Potential energy = mgh where g be the gravitational force of the earth = 9.8m/s²
So,
Energy = 1.5×9.8×21 J
= 308.7 J.
Hence,
The energy is 308.7 J.
Q 17. Given,
Mass (m) = 1120 kg
Speed (v) = 40 m/s
To find out the energy.
We will find out the kinetic energy as the car is in motion.
Formula
Kinetic energy = 
mv²
So,
Energy = ×1120×40² J
= 896000 J
Hence,
The energy is 896000 J.
You have 1, 2, 3, 4, 5, and 6 on a dice. Only 2 of 6 are the rolls that you want. Therefore, it is 2/6, which simplifies to 1/3.
