the quotient of n and 6
ASAP I need an answer today will give 100 points and mark brainliest PLSSSSSSSSS :)
Answer:
The quotient of n and 6 is n/6, as quotient means divide.
for example, if it was "the quotient of 24 and 6", it would be 24/6, which is 4.
Which form do you prefer when finding the vertex of a quadratic function, vertex or standard? Why?
Johanna buys two poster frames that have the same area, but different shapes. One is a rectangular frame with a width of 40 inches and a length of 30 inches. The other frame is square. What a poster with dimensions of 36 inches X 36 inches fit in the square frame?
Answer:
No, the poster would not fit in the frame
Step-by-step explanation:
A rectangle is a quadrilateral (has 4 sides and 4 angles) with two pair of opposite and equal sides.
A square is a quadrilateral in which all sides are equal.
Given that the rectangular frame has a width of 40 inches and a length of 30 inches. The area of the rectangular frame is:
Area of rectangular frame = length * breadth = 40 inches * 30 inches = 1200 in²
Since the square frame has the same area as the rectangular frame, hence:
Area of square frame = length * length
length² = 1200
length = √1200 = 34.64
Therefore the dimensions of the square frame is 34.64 inches by 34.64 inches.
Hence a poster with dimensions of 36 inches X 36 inches cannot fit in the square frame.
Sonja wants to find the mass of her parakeet. What unit would be best to measure the bird’s mass?
Answer:
Died speciman prior would be best to measure the bird’s mass.The length (also bill-to-tail length) of a bird is usually measured from dead specimens prior to their being skinned for preservation. The measurement is made by laying the bird on its back and flattening out the head and neck gently and measuring between the tip of the bill and the tip of the tail.
A coffee shop offers coffee either iced or hot in sizes small, medium, and large. The flavor options are vanilla,
hazelnut, and caramel. If you received a coffee at random, what is the probability you would receive a large,
iced, hazelnut coffee?
Answer:
1/18
Step-by-step explanation:
There are 2 x 3 x 3 = 18 combinations of coffee. Only one is large, iced and
hazelnut
So, the probability is 1/18
A chair rental company charges $100 for delivery plus $3 per chair.
Write an explicit function for the total cost, T(c), of renting c number of
chairs.
Answer:
T(c) = 100 + 3*c
Step-by-step explanation:
cost = fee + cost per chair * number of chairs
T(c) = 100 + 3*c
Answer:
T ( c)= $ 100 + $ 3 c
Step-by-step explanation:
Given that :-
Fee for delivery = $ 100Cost per chair = $ 3No. of chair = cTo Find :-
Total cost T( c) of renting c no. of chairs.Solution :-
Total Cost, T ( c) = Fee + cost per chair × no. of chairs.
T ( c) = $ 100 + $ 3 × c
T ( c) = $ 100 + $ 3 c
Tenemos 2 garrafas una al 20% y otra al 30%. Cual es su capacidad de las garrafas si tenemos 12 litros de agua
Answer:
Cada garrafa tiene una capacidad de 24 litros.
Step-by-step explanation:
Tenemos dos garrafas, definamos V como el volumen que cada garrafa tiene.
Sabemos que una de las garrafas tiene el 20%, entonces el volumen de agua que tiene esta garrafa es:
(20%/100%)*V
Y la otra garrafa tiene el 30%, entonces esta garrafa tiene:
(30%/100%)*V
El volumen total de agua es la suma de esos dos volúmenes, que nos da:
(20%/100%)*V + (30%/100%)*V
Y sabemos que tenemos 12 L de agua, entonces podemos escribir la ecuación:
12 L = (20%/100%)*V + (30%/100%)*V
Ahora podemos resolver esto para V.
12L = 0.2*V + 0.3*V
12L = 0.5*V
12L/0.5 = V
24L = V
Cada garrafa tiene una capacidad de 24 litros.
Which of the following expressions are equivalent?
1. 5(a + 3)
2. 5a + 15
3. 3(2a + 5)
Answer:
1 and 2 are equivalent
For 1 , use distributive property. Distribute 5 to a and 3. 5 x a = 5a, and 5 x 3 = 15. Therefore, 5a + 15. This is why 1 is equivalent to number 2.

What are the solutions to the quadratic equation below?
4x^2 + 28x + 49 = 5
Answer:
C
Step-by-step explanation:
Answer:
C.
[tex]x=\frac{-7±\sqrt{5 } }{2}[/tex]
Step-by-step explanation:
4x² + 28x + 49 = 5
4x² + 28x + 49 - 5 = 0
4x² + 28x + 44 = 0
4(x² + 7x + 11) = 0
4(x² + 7x + 11) ÷ 4 = 0 ÷ 4
x² + 7x + 11 = 0
[tex]x=\frac{-b±\sqrt{b^{2}-4ac } }{2a}[/tex]
Ignore the A before the ±. It wouldn't let me type it correctly.
a = 1
b = 7
c = 11
[tex]x=\frac{-7±\sqrt{7^{2}-4((1)(11)) } }{2(1)}[/tex]
[tex]x=\frac{-7±\sqrt{49-4((1)(11)) } }{2(1)}[/tex]
[tex]x=\frac{-7±\sqrt{49-44 } }{2(1)}[/tex]
[tex]x=\frac{-7±\sqrt{5 } }{2(1)}[/tex]
[tex]x=\frac{-7±\sqrt{5 } }{2}[/tex]

Find the area of the circle.
Use 3.14 for pi
Answer: 153.94
Step-by-step explanation: Formula for area of a circle: pi * r^2
First find the radius by dividing the diameter by 2: 14/2 = 7
Then plug the radius, 7, and pi, 3.14, into the formula:
(3.14) * (7^2) = 153.94 inches squared

Answer:
3rd one down is the answer
Answer:
Well let's count how many 65's there are, there are 3
So there needs to be 3 dots on the data plot on top of the section, 65.
Let's exclude some answers, D and B since they don't have 3 hovering over the 65(since there are three 65's).
Let's count how many 67's there are, there are 4.
We need to get rid of any answers that are more than 4 or less than 4 that are hovering over the section of 67. There are no answers to get rid of, let's move onto the next number, 68! There are four 68's. Let's also get rid of any answers that have more than 4 or less than 4 on the section above 68 since we're looking at that number. C is our answer!
Eleisha is standing facing East. She turns in a clockwise direction and is now facing West. Through how many degrees did Eleisha turn.
Answer:
180 degrees
Step-by-step explanation:
East and west are two opposite directrions along the same line.
The angle is 180 degrees.
Answer: 180°
Step-by-step explanation: The directions on a compass would look something like this; (Refer to the image.)
A full circle is 360°. Half of 360 is 180. You would have to make a clockwise rotation by 180° to face West. Think of this picture as a clock or a circle.

Could anyone offer a step by step on how to solve this problem?
Answer:
[tex]m\angle 1 = 40^\circ[/tex]
Step-by-step explanation:
First, notice that the two lines are parallel as indicated by the arrow.
Therefore, by the Alternate Interior Angles Theorem:
[tex]\angle 1\cong \angle 2[/tex]
So:
[tex]m\angle 1 = m\angle 2[/tex]
Substitute:
[tex](2x+20)=(3x+10)[/tex]
Solve for x. Subtract 2x from both sides:
[tex]20=x+10[/tex]
And subtract 10 from both sides:
[tex]x=10[/tex]
We know that:
[tex]m\angle 1 = 2x+20[/tex]
Substitute. Hence:
[tex]m\angle 1 =2(10)+20=40^\circ[/tex]

How many positive whole numbers less than or equal to 360 are divisible by 2 or 3, but are not divisible by 18?
Answer:
You can do this through trial and error.
The answer is 260.
Step-by-step explanation:
Off the bat, we know all even numbers are multiples of 2 so 180 numbers to be precise. Now we find how many even Numbers are divisible by 18 so all factors of 18 should be satisfactory so 18, 36 etc. there are 20 of those so 180 - 20 = 160
now multiples of 3. 360 dived by 3 is 120 - 20 =100, 100+160 = 260

In triangle HIJ, N is the centroid. If HK = 10, find KI.
Given:
In triangle HIJ, N is the centroid and [tex]HK=10[/tex].
To find:
The value of KI.
Solution:
In a triangle, the centroid of the triangle is the intersection of its medians.
Median of a triangle from a vertex divides the opposite side into two equal parts.
It is given that, N is the centroid. It means JK, HL and IM are the medians of the triangle HIJ.
Since JK is a median of the triangle HIJ, therefore it divides the opposite side IH into two equal parts.
[tex]KI=HK[/tex]
[tex]KI=10[/tex]
Therefore, the value of KI is 10 units.

Answer:
✅On average Albany gets 20.967 inches rain pee year and Zachary gets 25.153 inches rain per year.
✅On average, it rains more in Zachary in a year.
Step-by-step explanation:
Mean annual rainfall on average = total amount of rainfall for the period of years ÷ 10
✔️Mean Annual rainfall for Albany (in.):
= (22.82 + 19.83 + 28.40 + 23.35 + 30.78 + 21.34 + 11.20 + 17.04 + 18.63 + 16.28) ÷ 10
= 20.967
✔️Mean Annual rainfall for Zachary (in.):
= (26.41 + 23.54 + 30.02 + 26.35 + 34.24 + 25.74 + 18.98 + 21.26 + 23.61 + 21.38) ÷ 10
= 25.153
✅Therefore, on average Albany gets 20.967 inches rain pee year and Zachary gets 25.153 inches rain per year.
✅On average, it rains more in Zachary in a year.

12x+24x +18 = 36x +24 -6
Combining like terms
36x+18 = 36x +18
Subtracting 36x from each side
18 = 18
This is always true so it does not matter what x is, the left had side will equal the right hand side
