Answer:
1.56
Step-by-step explanation:
156 divided by 100
Answer:
1.56
Step-by-step explanation:
To convert a percentage to a decimal, you must divide the number by 100 because percentages are out of 100. 156 percent can also be written as 156/100 which you can simplify to 1.56.
every 30 seconds, Joan places a correct puzzle piece. How long would it take her to complete a 3000 piece puzzle?
Answer:
it will take her 90000 seconds to complete 3000 piece of puzzle
Step-by-step explanation:
every 30 seconds, a correct puzzle piece , meaning 1 piece
how long would it take her to complete a 3000 piece puzzle
so let x = how long it would take her to complete a 3000 piece puzzle
so if 30 seconds = 1 piece
x seconds = 3000 piece
x = 90000 seconds
A bathtub holds 80 gallons of water. Water drains out of the tub at a rate of 2 gallons every thirty seconds. At this rate, how many minutes will it take a full bathtub to drain completely?
Given :
A bathtub holds 80 gallons of water.
Water drains out of the tub at a rate of 2 gallons every thirty seconds.
To Find :
How many minutes will it take a full bathtub to drain completely.
Solution :
We know, 30 seconds = 0.5 minute.
Rate of water flow per minute is given by :
[tex]R = \dfrac{2}{0.5}=4 \ gallons/min[/tex]
Let, bathtub will completely drain in x minutes.
So, 4x = 80
x = 80/4
x = 20 minutes
Hence, this is the required solution.

Identify the slope of the following line y = - 2x + 7
Pleasee
Answer:
-2 or -2/1
Step-by-step explanation:
Since the equation is in y = mx + b form with m equaling the slope, we can see that -2 is in m's place, so -2 is the slope.

Yes, sameMs. W has 400 followers on Twitter and is gaining 75 followers each day. Mrs. Hill has 1,000 followers on Twitter, but is losing 25 followers a day. How many days will it take them to have the same number of followers?
Answer:
It takes 6 days.
Step-by-step explanation:
First, you have to form expressions for both of them in terms of x. Let x be the number of days :
Ms. W = 400 + 75x
Mrs. Hill = 1000 - 25x
Next, you have to compare it as we want to find out how many days in takes for them to have the same number of followers :
400 + 75x = 1000 - 25x
75x + 25x = 1000 - 400
100x = 600
x = 6
7 + y = 5(2y – 1) + 3y
Answer:
y = 1
Step-by-step explanation:
Given
7 + y = 5(2y - 1) + 3y ← distribute and simplify right side
7 + y = 10y - 5 + 3y
7 + y = 13y - 5 ( subtract y from both sides )
7 = 12y - 5 ( add 5 to both sides )
12 = 12y ( divide both sides by 12 )
1 = y
The population of Latvia in 1989 was 2 700 000. In 1994 it was 2 500 000. Calculate the percentage decrease in the population between 1989 and 1994
Answer:
7.4%
Step-by-step explanation:
Given parameters:
Population of Latvia in 1989 = 2700000
Population of Latvia in 1994 = 2500000
Unknown:
Percentage decrease in population = ?
Solution:
The change in population;
Change in population = 2700000-2500000 = 200000
Percentage decrease = [tex]\frac{Population change }{Population in 1989} x 100[/tex]
Percentage decrease = [tex]\frac{200000}{2700000}[/tex] x 100 = 7.4% decrease

Which of the following equations is correct? select three that apply
A) 0.12 = 4/33
B) 0.4 = 2/5
C) 0.54 = 6/11
D) 0.7 = 7/9
E) 0.83 = 5/6
F) 0.91 = 41/45
Answer:b,e,f
Step-by-step explanation:
The correct equations are:
B) 0.4 = 2/5
D) 0.7 = 7/9
E) 0.83 = 5/6
To determine which of the following equations is correct, we need to compare each decimal value to its equivalent fraction. Here are the correct equations:
B) 0.4 = 2/5
D) 0.7 = 7/9
E) 0.83 = 5/6
B) 0.4 is equivalent to 2/5 because 0.4 means 4 tenths, and 2/5 also represents 4 tenths (2 parts out of 5).
D) 0.7 is equivalent to 7/9 because 0.7 means 7 tenths, and 7/9 also represents 7 tenths (7 parts out of 9).
E) 0.83 is equivalent to 5/6 because 0.83 means 83 hundredths, and 5/6 also represents 83 hundredths (5 parts out of 6).
The remaining options (A, C, and F) are not correct as their decimal values do not match their corresponding fractions.

A gym charges $8.75 for each swimming class and a one-time registration fee of $12.50. A student paid a total of $56.25. How many swim classes did the student take?
Answer:
He took 5 swimming classes.
Step-by-step explanation:
The problem states that the student paid a total of $56.25 for the classes and also the one-time registration fee. To find the number of classes, we should first subtract the one-time registration fee from the total.
$56.25 - $12.50 = $43.75
Now that we know he spent a total of $43.75 on the classes without the registration fee, we can divide that number by the cost of one class ($8.75) to calculate the total number of classes he took.
43.75 / 8.75 = 5

An airplane is preparing to land at an airport. It is 41,300 feet above the ground and is descending at the rate of 3,100 feet per minute. At the same airport, another airplane is taking off and will ascend at the rate of 2,800 feet per minute. When will the two airplanes be at the same altitude and what will that altitude be? Use pencil and paper. Use two other methods to solve the problem. Explain which methods are easier to use and which are more difficult to use for the situation.
9514 1404 393
Answer:
after 7 minutes19,600 feetStep-by-step explanation:
Here's the "pencil and paper" solution:
The two altitude equations are ...
y = 41300 -3100xy = 2800xThey can be solved by setting the expressions for y equal to each other.
2800x = 41300 -3100x
5900x = 41300
x = 41300/5900 = 7
y = 2800·7 = 19600
The planes will both be at 19,600 feet after 7 minutes.

Attached are solutions from a graphing calculator, and from a calculator app that is able to solve systems of equations.
I find the graphing calculator the easiest to use. I can enter equations using a keyboard, and the solution is displayed in a form that can be copied and pasted.
The calculator app on my phone requires equation entry using a small on-screen keyboard, with multiple key hits required to access some functions. (y is obtained by hitting the x key twice, for example.)
The "pencil and paper" solution is not so difficult, but requires a certain amount of writing (or good short-term memory). The solutions for x and y require separate calculations, whereas the other methods give both x and y at the same time.
In 1974 a mother was 6 times as old as her daughter. If the mother turned 50 in the year 2000, in what year was the mother double her daughter’s age?
This is in the topic of linear equations and please provide an explanation. (The working out)
Answer:
1990
Step-by-step explanation:
Since the mother was 50 years old in 2000, she was 50 - (2000-1974) = 50 - 26 = 24 years old in 1974.
Hence, the daughter was 24/6 = 4 years old in 1974.
In "x" years after 1974, the daughter will be 4+x years old, while the mother will be 24+x years old.
We need to find "x" from the equation
2(4 + x) = 24+x.
8 + 2x = 24 + x,
x = 24 - 8 = 16.
1974 + 16 = 1990.
Answer In 1990 the mother doubles her daughter's age
Check In 1990 mother's age is/was 24 + 16 = 40 years.
In 1990 the daughter's age is/was 4 + 16 = 20 years.

Nina can type 124 words in 4 minutes.at this rate how many words can nina type in an hour
Answer:
1,860
Step-by-step explanation:
FIRST:
we divide 124 by 4 because in 4 minutes he can type 124 words, and we need to figure out how many he can type in a minute.
124 divided by 4 is 31. (they can type 31 wpm)
NEXT: now we know they can type 31 wpm, we need to multiply that number by 60 because there are 60 minutes in an hour.
31 x 60 = 1,860
therefore, they can type 1860 words per hour
