Lynn's track team practices for 3 weeks before their first meet. The coach wants them to get in a total of 720 minutes of practice time before the first meet. If the track team meets every Monday, Wednesday, and Friday for 70 minutes, will they have enough practice time before the first meet? Explain.
Answer:
No
Step-by-step explanation:
By the time they meet at their first meet, they would have practiced for 630 minutes total.
70*3=210
If they meet every three days each week for 70 mins each day then I would have to multiply the answer to learn how many minutes they gain each week.
210*3=630
If they have 210 mins per week and they only meet 3 times before the first meet, they will have only met for a total of 630 mins.
Which function graph represents the following scenario?
The number of students per classroom can be represented by the equation y = 22x.
Question 9 options:
Answer:
The third graph
Step-by-step explanation:
We can immediately eliminate the 1st and last graphs because they are decreasing, not increasing. It wouldn't make sense that the more classrooms there are, the fewer students. Y = 22x would be increasing in the graph.
Let's plug some x values into the equation first, to see where our points are at.
Plug 1 into x
Y = 22(1)
Y= 22
(1,22)
Plug 2 into x
Y = 22(2)
Y = 44
(2,44)
Plug 3 into x
Y = 22(3)
Y = 66
(3,66)
Plug 4 into x
Y = 22(4)
Y = 88
(4,88)
The second graph matches the coordinates, so it works, but it isn't a complete function graph. A function graph needs a line drawn through the points. The second graph isn't your answer.
Let's look at the third graph. The coordinates also match up with the graph and it has a line drawn through the points. It's an accurate function graph representing this scenario. Therefore, the third graph is your answer.

Greenwood Company manufactures two products—15,000 units of Product Y and 7,000 units of Product Z. The company uses a plantwide overhead rate based on direct labor-hours. It is considering implementing an activity-based costing (ABC) system that allocates all of its manufacturing overhead to four cost pools. The following additional information is available for the company as a whole and for Products Y and Z:
Activity Cost Pool Activity Measure Estimated Overhead Cost Expected Activity
Machining Machine-hours $ 231,000 11,000 MHs
Machine setups Number of setups $ 180,000 300 setups

Number of products 1 1
Direct labor-hours 9,000 1,000
Product Y would be allocated 20% of the machine setups cost
Product Z would be allocated 80% of the machine setups cost
What is activity-based costing?
Activity-based costing is a costing method where overhead cost of production are allocated based on the cost driver responsible for the overhead rather than using the plantwide overhead rate based on direct labor-hours.
In this case, we need to first of all determine the machine setups cost per per setups, based on the fact there 300 setups for both products Y and Z
machine setup cost per setup=Machine setups cost/Number of setups
Machine setups cost=$180,000
Number of setups=300
machine setup cost per setup=$180,000/300
machine setup cost per setup=$600
Total set up cost for product Y=60*$600=$36000
Total set up cost for product Y as %=$36,000/$180,000=20%
Total set up cost for product Z=240*$600=$144,000

Let us understand the properties of Logarithms. In mathematics Logarithms are the inverse of exponential function. In the simplest case, the logarithm counts the number of times same factor in present in a repeated multiplication.
Logarithm of base 10 is also known as common logarithm.Logarithm of base e is called natural logarithm also written as( [tex]ln[/tex])A logarithm of a number 'x' to a base 'y' is defined as:
[tex]log_y^x=z (y > 0)[/tex]
which represents [tex]y^{z} =x[/tex]
According to the properties of Logarithm :
Product Law: [tex]log (a)+log(b)=log(ab)[/tex]Quotient Law: [tex]log (a)-log(b)=log(\frac{a}{b} )[/tex]Power Law: [tex]alog (x)=log(x)^{a}[/tex]Now let us solve the given problem:
[tex]2 log (x-y)=log x+ log y\\or,log(x-y)^2=log(xy)\\or,log(x^2+2xy+y^2)=log(xy)[/tex]
[tex]or,x^{2} +2xy+y^{2}=xy\\[/tex] ( taking anti-logarithms on both sides)

Now let us use the above equation to solve
Left Hand Side:
[tex]2 log(x+y)\\=log(x+y)^2\\=log(x^{2} +2xy+y^{2} )\\=log(x^2+y^2+2xy)\\=log(xy+2xy+2xy)\\=log(5xy)\\=log(5)+log(x)+log(y)[/tex]

Can someone solve just the c problem
Applying the distributive property, the solution of x for item c is given as follows:
x = (3a - 8 - b)/(a - b).
What is the distributive property?The distributive property is when the outside term multiplies each of the inside terms of an expression.
For example, in this problem:
a(x - 3) = ax - 3a.b(x - 1) = bx - b.Hence the solution for x of the expression is found as follows:
a(x - 3) + 8 = b(x - 1).
ax - 3a + 8 = bx - b
ax - bx = 3a - 8 - b
x(a - b) = 3a - 8 - b

The mixture requires 200 ounces of 40% alloy.
What is defined as the mixture?A mixture is a physical combination of two or more substances that retain their identities and are blended as solutions, suspensions, or colloids.
An alloy is a metallic substance made up of two or more elements that can exist as a compound or a solution. Alloy components are typically items, though carbon, a nonmetal, is a necessary component of steel.x = amount of 40% copper
400 = amount of 70% copper
x + 400 = total amount of copper = amount of 60% copper
Set a correctly weighted mixture of x and 300 equal to the a weighted (x+300), in which the weights are decimal percentages;
40% is 0.4, 70% is 0.7, and60% is 0.60.4x + 0.7(400) = 0.6(x + 400)
Solve for x:

Suppose that you're designing a concrete patio. The patio will have height of 6 inches (1/2 foot) and have a rectangular base with a perimeter of 70 feet. If you have 138 cubic feet of concrete, what are the dimensions of the concrete patio?
The dimensions of the concrete patio should be 23ft x 12ft x 0.5feet.
What are the dimensions of an object?Since a rectangle is two-dimensional, while a cube is three-dimensional, the dimensions of the concrete patio include its length, width, and height or thickness.
Data and Calculations:The quantity of concrete required = 138ft³
The perimeter of the patio = 70 feet
Height = 6 inches or 1/2 foot or 0.5 ft
Perimeter = 2(L + W)
70 = 2(L + W)
L + W = 35 (70/2)
The possibilities for the length and width include 20 and 15, 25 and 10, and lastly, 23 and 12, which are also the two pair factors of 276.
Let L = 23 (the length is always longer than the width)
W = 12 (35 - 23)
Check:
Volume of concrete = 138ft³
Area = 276ft² (138ft³/0.5ft)
Two pair factors of 276 are 92 and 3, 46 and 6, 23 and 12, 2 and 138, and 1 and 276.
Given also that (23 + 12)2 = 70 (perimeter)
The dimensions that meet the two requirements are:
Length = 23 feet
Width = 12 feet
and Height = 0.5 feet
= 23 x 12 x 0.5 = 138

A ball is thrown up on the surface of a moon. It’s height above the lunar surface (in feet) after ‘t’ seconds is given by the formula
h =592t - 16/7t^2
Find the time that the ball reaches its maximum height.
Step-by-step explanation:
we get the points with extreme values as the 0 points of the first derivative of the function.
h'(t) = 592 - 32/7 t = 0
592 = 32/7 t
4144 = 32t
t = 129.5 seconds
so, it will reach its max. height after 129.5 seconds.
The time that the ball reaches its maximum height is 129.5 seconds.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The height above the lunar surface (in feet) after ‘t’ seconds is given by the formula;
⇒ h =592t - 16/7t²
Now,
We have to find the derivative of above formula and equate to zero for the maximum time as;
⇒ h =592t - 16/7t²
⇒ h' =592 - 16/7 × 2t = 0
⇒ 592 - 32/7 t = 0
⇒ 32/7 t = 592
⇒ 32t = 592 × 7
⇒ 32t = 4,144
⇒ t = 4,144/32
⇒ t = 129.5 seconds.
Thus, The time that the ball reaches its maximum height is 129.5 seconds.
