The correct answer is 4.8 hours
Explanation:
This mathematical problem can be solved by using the rule of three, which involves finding an unknown value by using three related values. The process is shown below:
1. It is known a fully charged battery (100% battery) lasts 16 hours. This can be represented as 100 = 16. But it is not know how much a 30% battery last; this can be represented as 30 = x.
2. Write all the values
100 = 16
30 = x
3. Cross multiply to create an equation and solve the equation
100 x = 48
x = 480 / 100
x = 4.8

A number n is no less than -3. what is the inequality
Answer:
n ≥ -3
Step-by-step explanation:
If n can be no less than -3... then we know that n has to be bigger than or equal to -3.
This could also be said as greater than or equal to -3
Conveniently enough... there is a sign for greater than or equal to and it is ≥

What is angle MNT? Help
Answer: acute
Step-by-step explanation: it is less than 90 degrees so it is less the right angle
120 degrees.
Angle MNT is equal to its opposite angle, (I cant tell you the angle as one of the points is not showing, it uses T and Q)
Remember, all triangles have angles that when added together, equal 180 degrees.
So, add 35 and 25, which is 60.
Now subtract 60 from 180, 120.
Have a great day!

Question: Write a loop that inputs words until the user enters STOP.
Answer:
count = 0
word = input("User Input: ")
while word!="STOP":
count = count+1
print("You entered: "+str(word))
word = input("User Input: ")
print("All done. "+str(count)+" words entered")
Step-by-step explanation:
This line initializes counter variable count to 0
count = 0
This line prompts user for input
word = input("User Input: ")
The following iteration is executed until user enters STOP
while word!="STOP":
This increments counter variable by 1
count = count+1
This prints the word entered by the user
print("You entered: "+str(word))
This line prompts user for another input
word = input("User Input: ")
This prints the number of input by the user
print("All done. "+str(count)+" words entered")
Answer:
c = 0
word = input("Enter a word: ")
while word!="STOP":
c = c+1
print("#" + str(c) + ": You entered "+str(word))
word = input("Please enter the next word: ")
print("All done. "+str(c)+" words entered.")

Answer:
y=30x+55

Step-by-step explanation:
Exponential Decay Function
The exponential function is used to model natural decaying processes, where the change is proportional to the actual quantity.
An exponential decaying function is expressed as:
[tex]C(t)=C_o\cdot(1-r)^t[/tex]
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The element has an initial mass of Mo=970 grams, the decaying rate is r=27.7% = 0.277 per minute.
The equation of the model is:
[tex]M(t)=M_o\cdot(1-r)^t[/tex]
[tex]M(t)=970\cdot(1-0.277)^t[/tex]
Operating:
[tex]M(t)=970\cdot 0.723^t[/tex]
After t=13 minutes the remaining mass is:
[tex]M(13)=970\cdot 0.723^{13}[/tex]
Calculating:
M(13)=14.3 gram

Of the students in Jill's grade, 41 students have a pet and the other 7 students do not. What is the ratio of the number of students who do not have a pet to the total number of students?
Answer:
The answer is 7 : 48.
Step-by-step explanation:
First, you can to calculate how many students are there in Jill's grade by adding the number of students who have pet with the students without pets :
total = 41 + 7 = 48
Next, you have to find the ratio of students without pets to total students :
7 : 48
Answer:
SoluTion :-Total student = Student who have pet + Student who don't have pet
Total Student = 41 + 7
Total Student = 48

A map has a scale of 2 inches : 25 miles. Gabriel uses the map to find the
distance from the zoo to his house. The distance on the map is 5 inches. If
Gabriel bikes at a rate of 12.5 miles per hour, how long will it take him to get to
the zoo?
2 hours. It's extremely simple this is elementary grade, he needs to travel 25 miles and he's going 12.5 miles an hour, 12.5 x 2 = 25 So in 2 hours he reaches his destination.
The time it will take will be 5 hours.
What is ratio?"The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity. Ratios can be classified into two types. One is part to part ratio and the other is part to whole ratio. The part-to-part ratio denotes how two distinct entities or groups are related. For example, the ratio of boys to girls in a class is 12: 15, whereas, the part-to-whole ratio denotes the relationship between a specific group to a whole. For example, out of every 10 people, 5 of them like to read books. Therefore, the part to the whole ratio is 5: 10, which means every 5 people from 10 people like to read books."
The speed of the bike = 12.5 miles/hour
So, the distance will be = [tex]25/2 * 5 = 125/2[/tex]
Time taken = [tex]125/2 * 1/12.5[/tex]
= 5 hours
Hence, the time taken to get to the zoo = 5 hours

Answer:
a. 6
b. 12
c. [tex] y = 6x + 12 [/tex]
Step-by-step explanation:
a. Using two pairs of values given, (0, 12) and (1, 18)
Rate/slope = [tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{18 - 12}{1 - 0} = \frac{6}{1} = 6 [/tex]
Unit rate/slope (m) = 6
b. The starting value is the y-intercept (b). It is the value of of y when x = 0.
From the table, when x = 0, y = 12.
Therefore the starting value (b) would be 12.
c. The equation can be written in slope-intercept form, [tex] y = mx + b [/tex], where,
m = slope/rate = 6
b = starting value/intercept = 12.
Plug in the values into the equation
The equation would be:
✅[tex] y = 6x + 12 [/tex]

A coffee table is shaped like a square and has an area of 22 square feet. Find the length of the side of the table to the nearest tenth of a foot.
Answer:
4.69 feet
Step-by-step explanation:
If the table is a square, all the sides are equal and the area is the length of one side squared. A=l^2
The length must then be the square root of the area. The square root of 22 square feet is 4.6904 feet. Rounded to the nearest tenth, that is 4.69 feet.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of games downloaded = g
Number of songs downloaded = g + 8
Total number of songs and games downloaded = 30
Now,
g + (g + 8) = 30
g + g + 8 = 30
2g + 8 = 30
Subtract 8 on both sides.
2g = 30 - 8
2g = 22
Divide 2 on both sides.
g = 11
The number of games = 11
The number of songs = 11 + 8 = 19
Thus,
The number of games is 11.
The number of songs is 19.
