Arianna drove 180 miles in 3 hours. If she continued at the same rate, how long would it take to travel 960 miles?
Answer: 16 hours
Step-by-step explanation: If 180 miles was completed in 3 hours, it means 60 miles was completed in 1 hour (180 ÷ 3 = 60.) Now we just do 960 ÷ 60 and we get 16 hours of time at a constant speed, assuming no further alterations were made to accelerations.
If my problem was helpful, please mark it as Brainliest. It helps me earn reputation and ranks!
Arianna can travel 960 mi in 16 hours.
What is speed?Speed is defined as the rate of change of position of an object in any direction.
Given that, Arianna drove 180 miles in 3 hours.
As we know, Speed is the ratio of distance to the time in which the distance was covered.
Speed = distance/time
Ariana's speed = 180/3 = 60 mi/hr
Therefore, time taken by her to travel 960 mi = 960/60 = 16 hr.
Hence, Arianna can travel 960 mi in 16 hours.

2 2/3 * 2 2/3 = how many thirds as a fraction
Answer:
[tex]21 \frac{1}{3}[/tex] fit into the product
Step-by-step explanation:
so you want to convert [tex]2 \frac{2}{3}[/tex] into a fraction by multiplying 2 by 3 and adding it to the 2. This will give you (3 * 2) = 6 => 6+2=8 which is the numerator. So the fraction becomes [tex]\frac{8}{3}[/tex] and since the two fractions are equal they both become this. So now you have [tex]\frac{8}{3} * \frac{8}{3}[/tex] which can be calculated by multiplying the numerators and denominators. This gives you [tex]\frac{8*8}{3*3} = \frac{64}{9}[/tex]. Now this just gives you the product but the question is asking you how many one thirds is the product. This is essentially saying how many 1/3 fit into the product or in other words what is the product divided by 1/3. This gives you the equation [tex]\frac{64}{9} \div \frac{1}{3}[/tex] which can be calculated by changing the sign to multiplication and flipping the second fraction (1/3 => 3/1) This gives you the equation [tex]\frac{64}{9} * \frac{3}{1} = \frac{64 * 3}{3 * 3} = \frac{64}{3}[/tex]. I rewrote the 9 as 3 * 3 in the equation so you can see that we can just cancel out the 3. Since if have a number and multiply it by "x" and divide by "x" you just have the original number. So now you have 64/3 which simplifies to [tex]21 \frac{1}{3}[/tex]

Abbey Co. issued a credit memo for $2,500 for merchandise returned that originally cost $1,800. Gomez Co. paid the invoice within the discount period. What is the amount of gross profit earned by Abbey Co. on the above transactions?
Answer:
The amount of gross profit earned by Abbey Co. on the above transactions is $7,554.00
Step-by-step explanation:
What is the gross profit of Abbey Co?
Note that after sales of goods of $29,300 whose cost is $20,510 to Gomez Co, Gomez returned goods whose selling price is $2,500 and cost originally $1,800 to Abbey Co.
The implication of such goods returned is that $2,500 would be deducted from selling price and $1,800 would be deducted from cost of goods sold.
selling price=$29,300-$2,500
selling price=$26,800.00
cost of goods sold=$20,510-$1,800
cost of goods sold=$18,710.00
Note again that Gomez paid the invoice within the discount period, which means that net sales is the selling price of $26,800.00 minus 2% discount(2/15 means a discount of 2% is available if credit sales is settled in cash within the first 15 days of making sales0
net sales=$26,800.00*(1-2%)
net sales=$26,264.00
The gross profit is net sales minus the cost of goods sold
gross profit= $26,264.00-$18,710.00
gross profit=$7,554.00

What is an angle measure?An angle is formed when two lines or rays meet at a single point. The common point is referred to as the vertex. The length of the angle formed when two rays or arms intersect at a common vertex is known as an angle measure in geometry.
Angles and sides in relation to one another:
The biggest side and angle of any triangle are in opposition to one another.
The smallest side and angle in every triangle are on opposing sides.
The middle side and middle angle are always in opposition to one another in triangles.
When we extend vertex A further to the left of vertex B,
we increase the side length of AB.
As the length AB increases, the measure of opposite angle increases.
Let C be the angle opposite to AB.
Therefore, as the length AB increases, the measure of C increases.

Which statement does not describe the data set?
A. It has a range of 17.
B. It is symmetric.
C. It has a median of 12.
D. It has a mode of 12.
Answer: Choice A) It has a range of 17
Reason:
The smallest value is 8 and the largest is 14. The range is the distance between these min and max
range = max - min = 14 - 8 = 6
So the range is 6 instead of 17.
The range of a data set is the difference between maximum and minimum thus the range of the given data set 8, 10, 10, 12, 12, 12, 12, 14, 14,16 is 8 so option (A) does not describe the data set.
What are the mode and median?Mode is the highest frequency number while the median is the middle value of a data set after writing in either an increasing or decreasing manner.
For example;
Set { 1,2,2,3,4,5,6} here mode is 2 and median is 3.
As per the given data set.
8, 10, 10, 12, 12, 12, 12, 14, 14,16
The range = maximum - minimum
Range = 16 - 8 = 8
The median of the data set is 12.
The mode is the highest frequency thus 12 is the mode of the data set.
Hence "The range of a data set is the difference between maximum and minimum thus the range of the given data set 8, 10, 10, 12, 12, 12, 12, 14, 14,16 is 8".

Step-by-step explanation:
1 week is 3 rats
( w × 3 ) + 4
hope this helps
Answer:
P(w) = 3w+4
Step-by-step explanation:
For a Linear Equation , it takes the Form y = mx + c
where c is the Constant which is y-value at x=0
and the m is the Slope which is the change in y-value for a 1-unit change in x-value
So for our Question
y-value is represented by P(w) , Number of Rats
x-value is represented by w , Number of Weeks
So the Constant (c) is the P(w) at w=0 which is 4
and the Slope is the Change in P(w) value as w changes by 1 unit , which from week 0 to week 1 , P(w) changed from 4 to 7 , so the Change =7-4=3
Then the Slope m = 3
So the Linear Equation will be P = mw+c
Then P(w) = 3w+4

The length of one side of a triangle is 2 feet less than three times the length of its second side. The length of the third side is 3/4 of the sun of the lengths of the first two sides. Find the lengths of all three sides if the permitter of the triangle is 17.5 feet.
Using a system of equations, it is found that the lengths of the sides of the triangle are given as follows:
5.29 feet, 2.43 feet, 5.79 feet.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are the lengths, that are x, y and z.
The length of one side of a triangle is 2 feet less than three times the length of its second side, hence:
x = 3y - 2.
The length of the third side is 3/4 of the sun of the lengths of the first two sides, hence:
z = 0.75(x + y).
Find the lengths of all three sides if the perimeter of the triangle is 17.5 feet, hence:
x + y + z = 17.5.
3y + 2 + y + 0.75(3y - 2 + y) = 17.5
4y + 0.75(4y - 2) = 15.5.
7y = 17
y = 2.43 feet.
Hence:
x = 3y - 2 = 3 x 2.43 - 2 = 5.29 feet.z = 0.75(x + y) = 0.75(5.29 + 2.43) = 5.79 feet.More can be learned about a system of equations at https://brainly.com/question/24342899

How to write the formula of this function?Mathematically, the standard equation of a cosine function is given by:
y = Acos(Bx - C) + D
Where:
A is the amplitude.B = 2π/P.P is the period.C is the phase shift.D is the center line (midline).For the amplitude, we have:
A = maxline - midline
A = 10 - 4
Amplitude, A = 6.
Since the maxline to the midpoint is euqal to π/4, we have:
¼ × P = π/4
4P = 4π
P = π
For the value of B, we have:
B = 2π/P
B = 2π/π
B = 2.
Since there isn't any phase shift, the value of C is equal to zero (0) and D is equal to 4.
Next, we would substitute the parameters into the cosine function:

Evaluate: a) n!/(n-3)!
b) P(6,4)/4!
Step-by-step explanation:
a).
n! is
[tex]n(n - 1)(n - 2)(n - 3)(n - 4).........(1)[/tex]
(n-3)! is
[tex](n - 3)(n - 4)(n - 5)..........(1)[/tex]
If we divide the two, everything behind (n-3) will just cancel out so we would be left with only
[tex](n)(n - 1)(n - 2)[/tex]
So the answer to a is
[tex]n(n - 1)(n - 2)[/tex]
b
Permutations formula of P(6,4) is
6!/(6-4)!, or 6!/2!.
[tex] \frac{6 \times 5 \times 4 \times 3 \times 2 \times 1}{2 \times 1} = 360[/tex]
Then we divide by 4!
[tex] \frac{360}{4 \times 3 \times 2 \times 1} = 15[/tex]

A
Step-by-step explanation:
Complex roots of quadratic functions occur when the discriminant is negative.
Discriminant
[tex]b^2-4ac\quad\textsf{when}\:\:ax^2+bx+c=0[/tex]
Evaluate the discriminant of each of the given equations.
[tex]\textsf{A.} \quad 3x^2+2=0[/tex]
[tex]\implies a=3, \quad b=0, \quad c=2[/tex]
[tex]\implies b^2-4ac=0^2-4(3)(2)=-24[/tex]
As -24 < 0 the equation will have complex roots.
[tex]\textsf{B.} \quad 2x^2+1=7x[/tex]
[tex]\implies 2x^2-7x+1=0[/tex]
[tex]\implies a=2, \quad b=-7, \quad c=1[/tex]
[tex]\implies b^2-4ac= (-7)^2-4(2)(1)=41[/tex]
As 41 > 0 the equation does not have complex roots.
[tex]\textsf{C.} \quad 3x^2-1=6x[/tex]
[tex]\implies 3x^2-6x-1=0[/tex]
[tex]\implies a=3, \quad b=-6, \quad c=-1[/tex]
[tex]\implies b^2-4ac=(-6)^2-4(3)(-1)=48[/tex]
As 48 > 0 the equation does not have complex roots.
[tex]\textsf{D.} \quad 2x^2-1=5x[/tex]
[tex]\implies 2x^2-5x-1=0[/tex]
[tex]\implies a=2, \quad b=-5, \quad c=-1[/tex]
[tex]\implies b^2-4ac=(-5)^2-4(2)(-1)=33[/tex]
As 33 > 0 the equation does not have complex roots.

Hello
Answer:
Look at the picture.
The solution to the given proportion (x-1)/5 = (x-1)/2 is equal to x = 1.
To solve the proportion (x-1)/5 = (x-1)/2, we need to find the value of x that satisfies the equation. Cross-multiplication is a common method used to solve proportions.
First, cross-multiply the equation:
2(x - 1) = 5(x - 1)
Now, distribute the values on both sides:
2x - 2 = 5x - 5
Next, isolate the variable x on one side of the equation. Let's move all terms containing x to the left side of the equation by subtracting 2x from both sides:
2x - 2 - 2x = 5x - 5 - 2x
-2 = 3x - 5
Now, let's move the constant term (-5) to the other side of the equation by adding 5 to both sides:
-2 + 5 = 3x - 5 + 5
3 = 3x
Finally, to find the value of x, divide both sides by 3:
3/3 = 3x/3
1 = x

8x + 20y = 20
14x + 35y = k
For the above system of equations to be consistent, k must equal
Answer:
35
Step-by-step explanation:
The equations will be "consistent" when they describe lines that are not parallel.
SlopesThe slope of a line whose equation is written in this form is the opposite of the ratio of the y-coefficient to the x-coefficient:
line 1 slope = -8/20 = -2/5
line 2 slope = -14/35 = -2/5
These lines have the same slope, so will be parallel unless they have the same y-intercept.
Y-interceptThe y-intercept of each line is the ratio of the constant to the y-coefficient:
line 1 y-intercept = 20/20 = 1
line 2 y-intercept = k/35
We want these lines to have the same y-intercept so that they are not inconsistent. This requires ...
k/35 = 1
k = 35
For the equations to be consistent, we must have k = 35.

Additional comment
Linear equations are generally categorized as "consistent" or "inconsistent," and "dependent" or "independent."
Equations are "inconsistent" if there are no values of the variables that satisfy all of the equations. They are "dependent" if they describe exactly the same relation between the variables. "Consistent" equations may be "dependent" (describing the same line, as here), or "independent" (describing lines with different slopes.)
