The temperature in Quebec City was 5 degrees Celsius at 4 pm. By midnight, the temperature dropped 15 degrees. A number line has points negative 20, blank, A, B, 0, 5, C, blank, D. Which point is a representation of the colder midnight temperature in degrees Celsius?
Answer: Point A
Step-by-step explanation:
The temperature at midnight is;
= 5 - 15
= -10°C
Looking at the number line, one can surmise that the scale is in multiples of 5. This means that C is 10, B is -5 and A is -10.
With point A being -10°C, it represents the colder midnight temperature.
Answer:
Point A
Step-by-step explanation:
We know that the temperature dropped 15 degrees, and that it was initially of 5°C. So, by midnight, the temperature will be of -10°C (5-15=-10).
We also know that the distance between points is of 5°C. So, the point that we have to mark is point A, which represents -10°C.

The circumference of a round pillow is 46.8 centimeters. Find the radius of the pillow, in centimeters. Round your
answer to the nearest tenth.
Answer:
7.5 centimeters
Step-by-step explanation:
The circumference is pi times the diameter
46.8/3.14=14.9
The radius is half of the diameter
14.9/2=7.45
7.45 is rounded to 7.5

The bag contained only red marbles and white marbles. If the ratio of red marbles to white marbles was 5 to 4, what fraction of the marbles were white? *Complete the statement by providing the correct response in number form, using / as the fraction symbol.
The fraction of white marbles is
Answer:
The fraction of white marbles is 4/9
Step-by-step explanation:
The fraction of white marbles is 4/9. This is because the ratio provided states that for every 5 red marbles in the bag there are 4 white marbles. Therefore, in a set of 9 total marbles (5+4) we can assume that exactly 4 of those marbles will be white since that is the ratio that has been provided. If there are a total of 18 marbles we can assume that exactly 8 will be white marbles, and so on. Each of which represent the fraction of white marbles in the bag as 4/9

Step-by-step explanation:
Given: -2(v-2)=-3-2v
Distribute -2 at the left side of the equal sign:
-2v+4=-3-2v
Put all like terms in one side:
-2v+2v=-3-4
Combine all like terms:

one number is two more than triple a second number. Their sum is 30. what is the smaller number
Answer:
7
Step-by-step explanation:
We can solve this problem by making an equation.
Let x represent the second number
3x + 2 will be the first number because it is 2 more than triple x
This makes our equation:
3x + 2 + x = 30
Combine like terms
4x + 2 = 30
Subtract 2 from both sides
4x = 28
Divide both sides by 4
x = 7
The smaller number aka the second number is 7

graph the line that passes through( -1,5)perpendicular to a line whose slope is -1/6
Answer:
y - 5 = 6(x+1)
Step-by-step explanation:
if it is perpendicular to a line whose slope is -1/6, the slope of this line is the negative reciprocal which is 6.
y - 5 = 6(x+1)
this is point slope form btw

£50 is divided between Krutika, Natasha & Richard so that Krutika gets twice as much as Natasha, and Natasha gets three times as much as Richard. How much does Krutika get?
Answer:
£30
Step-by-step explanation:
→ Model the situation in terms of x
Richard = x, Natasha = 3x and Krutika = 6x
→ Now put the values into ratio form
6x : 3x : x = 50
→ Collect the x terms
10x = 50
→ Divide both sides by 10 to isolate
x = 5
→ Substitute x = 5 into Krutika
6 × 5 = 30
Answer:
£30
Step-by-step explanation:
Let's break down the information given to help us find how much Krutika gets.
"Natasha gets three times as much as Richard" - We can express the value that Natasha gets as [tex]3r[/tex] in terms of what Richard gets.
"Krutika gets twice as much as Natasha" - We can express this as [tex]2(3r)[/tex] which equals [tex]6r[/tex].
We know that the total money is £50, so we can write the equation:
[tex]r+3r+6r=50[/tex]
[tex]10r = 50[/tex]
[tex]r=5[/tex]
∴ Richard gets £5.
Since the money Krutika gets can be expressed as [tex]6r[/tex]:
[tex]6(5) = 30[/tex]
∴ Krutika gets £30.
Hope this helps :)
A consistent and dependent system of linear equations has how many solutions?
Answer/Step-by-step explanation:
If a system has at least one solution, it is said to be consistent . If a consistent system has exactly one solution, it is independent . If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line.
Gabby is an aspiring country artist. She has a record contract that pays her a base rate of $200 a month and an additional $12 for each album sold. Last month she earned a total of $644. Identify the y-intercept in the equation.
Answer:
From the formula above, you see that your slope would be the $12.
Step-by-step explanation:
So, from this problem the base rate is the y-intercept because it is fixed. The slope of the is the additional fee because it's changing by the number of albums sold. Below is the equation that should have been created using the slope intercept formula.
220 + 12x = 644
You will need the slope intercept form, y = mx + b
m is the slope
b is the y-intercept

Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of the two opposite interior angles.
so in first picture
1 is exterior angle of the triangle
it means that
1=2+3
so is evident that m 1 > m 2
in the second picture
1 is the exterior angle of the triangle
so
1=3+4
but 3=2 as alternate interior angles
definition:The Alternate Interior Angles Theorem states that if two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.
so is evident that m 1 > m 2
Answer:
see explanation
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
(1)
∠ 1 is an exterior angle of the triangle, then
∠ 1 = ∠ 2 + ∠ 3
Thus ∠ 1 must be > ∠ 2
(2)
∠ 3 = ∠ 2 ( alternate angles )
∠ 1 is an exterior angle of the triangle, then
∠ 1 = ∠ 3 + ∠ 4 = ∠ 2 + ∠ 4
Thus ∠ 1 > ∠ 2
convert the decimal number to the base stated
113 to base 6
Answer:
the answer is 341(I think)
113 = 3 • 36 + 5
(That is, 36 = 6² is the largest power of 6 that fits into 113. The next power 6³ = 216 exceeds 113.) Then
113₁₀ = 3 • 6² + 5 • 6⁰ = 305₆

Most staircases in use today have 9−inch treads and 8 12 −inch risers. What is the slope of a staircase with these measurements? Give your answer as a fraction or rounded to four decimal places, if necessary
Answer:
The value is [tex]m = 0.9022[/tex]
Step-by-step explanation:
From the question we are told that
The length of the treads is [tex]a = 9 \ inch[/tex]
The length of the risers is [tex]b = 8.12 \ inch[/tex]
Generally the slope of the staircase is
[tex]m = \frac{b}{a}[/tex]
=> [tex]m = \frac{8.12}{9}[/tex]
=> [tex]m = 0.9022[/tex]

Answer the following question and will mark Brainliest
Answer:
[0, ∞)
Step-by-step explanation:
The domain is the x values in a function. As you can see from the graph, the function touches zero (touching meaning the value zero is bracketed) and goes to infinity (infinity is parenthesis).
If a value is included it is bracketed. If it is not included it is used with parenthesis (infinity cannot be reached to it is used with parenthesis).
A book is marked down by 28 percent from an original price of $19.50. What is the new price?
Step-by-step explanation:
First find 28% of $19.50:
($19.50) / (100) × (28) = $5.46
Now minus the 285 from the original price:
($19.50) - ($5.46) = $14.04
The answer is $14.04
