Step-by-step explanation:
in the beginning, she missed 4 questions and received -20 points. it means that each question missed is equal to -5 points.
So, finally, when she missed 1/4 of the four questions, it means that she missed only one question. So, she only received -5 points
In January, a city’s snowfall was 5/8 foot below the historical average. In February, the snowfall was 3/4 foot above the historical average. Was the city’s snowfall in the two-month period above or below the historical average? By how much?
Answer:
The city's snowfall in the two-month period was above the historical average by 1/8 feet
Step-by-step explanation:
Fractions
The question provides the following information: In January, a city’s snowfall was 5/8 feet below the historical average. Let's assume the snowfall level to be positive if it's above the historical average and negative otherwise.
The data from January gives us a snowfall of -5/8 feet because it was below the average.
We also know in February, the snowfall was 3/4 foot above the historical average. Following our predefined convention, the data from February gives us a snowfall of +3/4 feet.
To know if the city's snowfall during the two-month period was above or below the historical average, we just need to add them, signs included.
If the result is negative, the two-month period showed a snowfall below the historical average.
Let's find the sum of
[tex]\displaystyle -\frac{5}{8}+\frac{3}{4}[/tex]
The LCM of 4 and 8 is 8, thus:
[tex]\displaystyle -\frac{5}{8}+\frac{3}{4}=\frac{-5+2*3}{8}=\frac{1}{8}[/tex]
Since this quantity is positive, we can say the city's snowfall in the two-month period was above the historical average by 1/8 feet.
Three friends entered a race around a track. Edward takes 6 minutes to run one lap. Bernie takes 3 minutes to run one lap and it takes Freddie 5 minutes to run one lap. If all three friends begin the race at the same time, how many minutes will it take for all three friends to be at the starting point again?
Answer:
It will take 30 minutes
Step-by-step explanation:
Here, we want to calculate the time it will take for the three friends to be at the starting point again
What we do here is to note the time it will take for each of the three friends to run a lap
That will be 6 , 3 and 5
What we now need to know the time is to find the lowest common multiple of the three amount of time
The lowest common multiple of 6,3 and 5 is 30
So the amount of time it will take the friends to be at the starting point again is 30 minutes

If the temperature at 7:00 am was - 7 degrees C and the temperature rose
8 degrees C during the morning, what was the temperature by noon?
Answer:
Temperature in noon = 1°C
Step-by-step explanation:
Given:
Temperature on 7:00 Am = -7°C
Temperature rose = 8°C
Find:
Temperature in noon
Computation:
Temperature in noon = Temperature on 7:00 Am + Temperature rose
Temperature in noon = -7°C + 8°C
Temperature in noon = 1°C
You have at most $3.65 to make copies for a school project. Each copy costs $0.25. Write and solve an inequality that represents the number of copies you can make.
The equation for the problem is [tex]0.25x[/tex] ≤ [tex]3.65[/tex]
Hope it helps!
You can make the maximum number of copies would be 14.6 which is determined by the inequality 0.25x ≤ 3.65 where x represents the number of copies.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
You have at most $3.65 to make copies for a school project. Each copy costs $0.25 which is given in the question.
As per the given condition, the required inequality would be:
⇒ 0.25x ≤ 3.65
Here x represents the number of copies
⇒ 0.25x ≤ 3.65
Divided by 0.25 both sides of the inequality, and we get
⇒ x ≤ 3.65/0.25
⇒ x ≤ 14.6
Therefore, you can make the maximum number of copies would be 14.6.

The red lines on the diagram show the layout for a running event. Runners will race around the triangle-shaped grassy area. What is the total length of the race course? what is The total distance in km.
Answer:
Total distance = 5.754 km
Step-by-step explanation:
Red lines of the right triangle show the layout of the race course.
Total length of the race course = Perimeter of the triangle
Perimeter of the triangle = Sum of the measures of all three sides
= 1.83 + 1.524 + 2.4
= 5.754 km
Therefore, total distance of the race course is 5.754 km.
Answer:

Step-by-step explanation:
1. Two phone plans offer 500 free minutes per month. Plan A charges $29.99 per month with a charge of $0.45 for each additional minute. Plan B charges $34.99 per month with a charge of $0.40 for each additional minute. 1. Write an inequality to find the number of additional minutes, m, for which Plan A costs more than Plan B for any given month.
Step-by-step explanation:
Plan A costs 100 minutes more than Plan B for the given month.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
Plan A is $29.99 per month plus $0.45 per minute further than the allotted time. Plan B costs $34.99 per month plus $0.40 for each additional minute.
According to the given question, we can write the inequality would be as:
⇒ 29.99 + 0.45m > 34.99 + 0.40m
⇒ 0.45m - 0.40m > 34.99 - 29.99
Apply the subtraction operation, and we get
⇒ 0.05m > 5
⇒ m > 5/0.05
Apply the division operation, and we get
⇒ m > 100 minutes
Therefore, Plan A costs 100 minutes more than Plan B for the given month.

3b+2(b-3)=4 Solve for b.
Answer:
b = 2
Step-by-step explanation:
3b + 2(b - 3) = 4
--distributive property-- 2(b - 3) = 2b - 6
3b + 2b - 6 = 4
(add like terms)
5b - 6 = 4
(add 6 to both sides)
5b = 10
(divide both sides by 5 to get b alone)
b = 2

What is the sine of an angle in a right angle triangle?The sine of an angle is the ratio of the height and the hypotenuse of the triangle.
Given, ∠C = 30°
AB = 16
Therefore, sin ∠C = (AB/AC)
Therefore, sin (30°) = 16/AC
⇒ (1/2) = 16/AC
⇒ AC = 2 × 16

Answer:
that is a negative slope
but dont know how to find the slope sorry
Step-by-step explanation:
[tex]\tt Step-by-step~explanation:[/tex]
Remember: To find the slope, we use the equation Rise/Run.
[tex]\tt Step~1:[/tex]
Let's find the rise first. Rise = How many units it goes up/down We can count down 6 units from the origin. Our rise is - 6.
[tex]\tt Step~2:[/tex]
To find the run. we count left/right. We could count 8 units. Our run is 8.
The slope is negative because it slopes downwards. If the slope is positive, then the line would be rising up.
[tex]\tt Step~3:[/tex]
To find the slope, we use the formula rise/run.
[tex]\tt \frac{-6}{8}=-\frac{3}{4}~or~ -0.75[/tex]

plz help me out! What is the result when x^3 + 6x^2 + 10x + 25 is divided by x+ 5?
Answer:
x² + x + 5
Step-by-step explanation:
Using Synthetic division
- 5 | 1 6 10 25
↓ - 5 - 5 - 25
-----------------------
1 1 5 0 ← remainder
Since the remainder is zero then (x + 5) is a factor of the polynomial
The Quotient = x² + x + 5
Thus
x³ + 6x² + 10x + 25 = (x + 5)(x² + x + 5)
