What is the speed of a walker who travels 500m in 192s?
Answer:
2.6m/s
Step-by-step explanation:
[tex]s = d \div t \\ \: = 500 \div192 \\ = 2.6ms \\ [/tex]
Answer:
9.375 km/h
Step-by-step explanation:
192 - 3 minutes 12 seconds
500m - 0,5 kilometers
60 x 60 = 3600
3600:192=18.75
500 x 18.75 = 9375
9375 meters - 9.375 kilometers
Match each expression with the equivalent expression.
2(6x + 6)
16x - 8
3(x - 2)
3(4x + 4)
2x + 6
4(x + 3)
Options for ALL:
4x + 12
2(x + 3)
8(2x - 1)
12x + 12
3x - 6
Answer: distributing
2(6x + 6) is 12x + 12
16x - 8 is 8(2x - 1)
3(x - 2) is 3x - 6
3(4x + 4) is 12x + 12
2x + 6 is 2(x + 3)
4(x + 3) is 12x + 12
Step-by-step explanation:
Distribute the number in front of the parenthesis to the numbers inside the parenthesis .
for example: 3(x-2)
3 times x = 3x
3 times -2= -6
answer: 3x - 6

Answer:
8 and 64
Step-by-step explanation:
4/1 = 4
8/2 = 4
32/8 = 4
64/16 = 4
Answer:
1:4
2:8
8:32
16:64
Step-by-step explanation:
The constant of proportionality is 1:4. Whatever number is on the right has to be 4 times greater than the number on the left for it to be proportional. I divided 32 by 4 to get 8 on the first one, and I multiplied 16 by 4 on the second one to get 64.
Hope this helps!
Help I guess? sorry I'm asking a lot of questions today
Answer:
63 houses have been sold this year.
Step-by-step explanation:
There are 81 houses in the community. If 7/9 are sold this year, then all you have to do is multiplication.
In this case, you would multiply 81 by 7/9 to get your answer.
81/1 x 7/9:
Cancel out the 9 and the 81. Then the denominator will be 1 x 1 and the numerator would be 7 x 9. It would be 63 (7x9=63) over 1 (1x1=1) which is just 63. Make sure to include units.
It takes Dennis 3 times as long as Vicki to read the paper each day. If it takes Dennis 36 minutes to read the paper, write and solve an equation to find how long it takes Vicki to read the paper.
Step 1: Define a variable to represent what you are solving for
Let ...
Step 2: Write an equation
Equation:
Step 3: Solve the equation using inverse operations
Solution:
Step 4: Write your answer sentence
Answer:
Answer:
Vicki takes 12 minutes.
Step-by-step explanation:
Call the time that Dennis takes to read; D
The time that Vicki takes to read is; V
As per the question;
Dennis takes 3 times as long as Vicki takes to read a paper, hence the equation formed is;
D = 3V
It is given that Dennis takes 36 minutes to read, hence
36 = 3V
Solve with inverse operations;
36 = 3V
/3 /3
12 = V

A weir is used to measure water flow in a channel. For a rectangular broad crested weir, the flow Q in cubic feet per second is related to the weir length L in feet and height H of the water by Q = 1.6LH3/2. Find the water height for a weir that is 3 feet long and has a flow of 38.4 cubic feet per second.
Answer:Find the water height for a weir that is 3 feet long and has flow of 38.4 cubic feet per second. SOLUTION: Therefore, the water height for the weir is 4 feet.
Answer:
the water height for the weir is 4 feet.

put the fraction in least to greatest 1/5, 5/5 ,4/5
Answer:
1/5, 4/5, 5/5
Step-by-step explanation:
1/5 is 20%
4/5 is 80%
5/5 is 100%
Hey there!
“Put the fraction in least to greatest 1/5, 5/5, and 4/5”
Given numbers:
• 1/5
• 5/5
• 4/5
• We can make this EASIER to solve by converting your given fraction(s) in decimals (and maybe percentages)
• 1/5 = 0.2 = 20%
• 5/5 = 1 = 100%
• 4/5 = 0.80 = 80%
• So now that we got that out of the way, we have your answer
Answer: 1/5 , 4/5 , 5/5 ☑️
Good luck on your assignment and enjoy your day!

Larry’s pet store made $30 before a pipe burst and he had to close early to get it fixed. He realized that he lost Three-fourths of a dollar each hour that the store was closed. If the expression that models this situation is 30 Negative three-fourths x, what is Larry’s profit if the store was closed for 8 hours?
Answer:
$24
Step-by-step explanation:
You will plug in 8 for x :)
30 - (3/4)x
Since he loses 3/4 a dollar for every hour he can't work, (3/4) x 8 = 6. He will lose 6 dollars from this. 30 - 6 = 24.
His final profit is 24.

Write inequalities to represent the situations below.
The vehicle's fuel efficiency is no less than 45 miles per gallon.
Use f to represent the vehicle's fuel efficiency (in miles per gallon).
Martina exercises at least 45 minutes per day.
Use t to represent Martina's amount of exercise (in minutes per day).
Answer:
[tex]f \ge 45[/tex]
[tex]t \ge 45[/tex]
Step-by-step explanation:
Solving (a): No less than 45
In inequalities, no less than means [tex]\ge[/tex]
So, the statement can be represented as:
[tex]f \ge 45[/tex]
Solving (b): At least 45
In inequalities, at least means [tex]\ge[/tex]
So, the statement can be represented as:
[tex]t \ge 45[/tex]
