We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal. If we subtract the same number from both sides of an equation, both sides will remain equal. or
A two-step equation is an algebraic equation that takes you two steps to solve. You've solved the equation when you get the variable by itself, with no numbers in front of it, on one side of the equal sign.

Every morning, Jim goes for a morning walk. His normal walking speed is 3 1/2 km per hour, and he walks a total distance of 10 km every day. How much time does he take to cover one km?
Hint 1 Notice the unit of Speed.
Hint 2 Can you figure out the distance covered in one hour
Answers
Answer:
Jim's walking speed = 312kmph
covered distance = 10km
time taken for one hour = ?
we know that: Distance =speed × time
=>Time = Distance/speed
=> Time = 10/312=5/156 hours
= Time = (5×60)/156=300/156=75/39=1.9 minutes

Answers
Answer:
19 cm³
Step-by-step explanation:
The figure cam be decomposed into two cuboid.
✔️Dimension of cuboid 1:
L = 2 cm
W = 1 cm
H = 8 - 3 = 5 cm
Volume = L * W * H
Volume = 2*1*5 = 10 cm³
✔️Dimension of cuboid 2:
L = 3 cm
W = 1 cm
H = 3 cm
Volume = L*W*H = 3*1*3
Volume = 9 cm³
✅Volume of the irregular figure = 10 + 9 = 19 cm³
If lines r and s are parallel, what would be the measurement of angle 6 if angle 1 was 2x+4 and angle 2 was 6x+8?
Answers
Answer: 134
Step-by-step explanation:
Angle 1 and 2 are supplementary and Angle 2 is congruent to Angle 6
Thus, first solve for x
8x+12=180
x = 21
Then solve for angle 2 which is congruent to angle 6
6(21) + 8 = 134

Find the area of this figure around your answer to the nearest 100. use 3.14 to approximate 3.14 as pi
Answers
Answer:
Area = 49.12 ft²
Step-by-step explanation:
The area of the figure = area of triangle + area of half of a circle
= ½*bh + ½(πr²)
b = 6 ft
h = 8 ft
r = ½ of 8 ft = 4 ft
π = 3.14
Plug in the values
Area of the figure = ½*6*8 + ½(3.14*4²)
Area = 24 + 25.12
Area = 49.12 ft²
Answer:
49.12

American League baseball teams play their games with the designated hitter rule, meaning that pitchers do not bat. The league believes that replacing the pitcher, traditionally a weak hitter, with another player in the batting order produces more runs and generates more interest among fans. Below are the average numbers of runs score in American League and National League stadiums for the first half of the 2001 season. **American:** 11.1, 10.8, 10.8, 10.3, 10.3, 10.1,10.0, 9.5, 9.4, 9.3, 9.2, 9.2, 9.0, 8.3 **National:** 14.0, 11.6, 10.4, 10.3, 10.2, 9.5, 9.5, 9.5, 9.5, 9.1, 8.8, 8.4, 8.3, 8.2, 8.1, 7.9 (a) Create two box plots to display this data and comment on what you see. (b) Estimate the mean number of runs scored in American League games with a 95% CI. What concerns do you have about making a similar CI for National League games
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
**American:**
11.1, 10.8, 10.8, 10.3, 10.3, 10.1,10.0, 9.5, 9.4, 9.3, 9.2, 9.2, 9.0, 8.3
**National:**
14.0, 11.6, 10.4, 10.3, 10.2, 9.5, 9.5, 9.5, 9.5, 9.1, 8.8, 8.4, 8.3, 8.2, 8.1, 7.9
Kindly view attached picture for boxplot :
Using the relation :
Mean ± Zcritical * s/sqrt(n)
Zcritical at 95% = 1.96
National league :
Mean = 9.58125
Standard deviation = 1.5
9.58125 - 1.96 * 1.5/4 = 8.84625
9.58125 + 1.96 * 1.5/4 = 10.31625
(8.84625 ; 10.31625)
American League :
Mean = 9.807
Standard deviation = 0.805
9.807 - 1.96 * 0.805/sqrt(14)= 9.3853152
9.807 + 1.96 * 0.805/sqrt(14) = 10.228684
(8.84625 ; 10.31625)

The population of a city has been increasing by 2% annually. In 2000, the population was 315,000. Predict the population of the city in 2020. Round your answer to the nearest thousand.
Answers
Answer:
In 2020 there will be 468,073 people.
Step-by-step explanation:
Giving the following information:
Growth rate (g)= 2% = 0.02
Population 2,000= 315,000
Number of periods (n)= 20 years
To calculate the population in 2020, we need to use the following formula:
FV= PV*(1+g)^n
FV= 315,000*(1.02^20)
FV= 468,073
In 2020 there will be 468,073 people.
