The baseball team purchased 22 bats and 50 gloves last year.
Explanation:To solve this problem, let's use a system of equations. Let x represent the number of bats and y represent the number of gloves purchased last year. We can set up the following equations:
20x + 12y = 1040 (equation 1) 25x + 16y = 1350 (equation 2)
We can solve this system of equations by using either the substitution method or the elimination method. Let's use the elimination method:
Multiply equation 1 by 5 and equation 2 by 4 in order to create equal coefficients for x:100x + 60y = 5200 100x + 64y = 5400 Subtract the equations to eliminate x:(100x + 64y) - (100x + 60y) = 5400 - 5200 4y = 200 y = 50
Now we can substitute the value of y back into equation 1 to solve for x:
20x + 12(50) = 1040 20x + 600 = 1040 20x = 440 x = 22
Therefore, the team purchased 22 bats and 50 gloves last year.

A person 6 ft tall casts a shadow 5ft long. at the same time, a nearby tree casts a shadow 31 ft long. find the height of the tree
Therefore, the tree's height is 37.2 feet.
We can use proportions to find the height of the tree based on the shadow it casts and compare it to the height and shadow of a known object (in this case, a person). Given that a person 6 ft tall casts a 5 ft long shadow, we can set up a proportion with the tree's 31 ft long shadow to find its height. The formula we use for this comparison is:
Person's Height / Person's Shadow = Tree's Height / Tree's Shadow
Plugging in the numbers:
6 ft / 5 ft = Tree's Height / 31 ft
Now, we solve for the Tree's Height:
6 ft * (31 ft / 5 ft) = Tree's Height
Tree's Height = 37.2 ft
Therefore, the height of the tree is 37.2 feet.

If it takes six men six days to dig six holes, how long will it take one man to dig half a hole?
It will take 3 days for 1 man to dig half of that complete hole.
What are direct and inverse proportion ?Direct proportion if increase in one quantity also results in increase in another quantity for example price and weight of something.
Inverse proportion is when increase in one quantity results in decrease in another quantity for example time is inversely proportional to (speed when distance is constant.
According to the given question
6 men are working together then it takes them 6 days to dig 6 holes.
∴ Number of men days = 6 days × 6 men = 36 men days
So, in 36 men days 6 holes are dug. Now the men days and the number of holes being dug are in direct proportion with one another.
Hence number of men-days required to dig one hole
= 36/6 men days
= 6 men days
∴ No. of men days required to dig half a hole
= 6/2
= 3 men days
So, It takes 1 man 3 days to dig half a hole.

The first aircraft has 75 more seats than the second aircraft. The third aircraft has 49 fewer seats than the second aircraft. If their total number of seats is 401, find the number of seats for each aircraft.
1st = 75+x
2nd = x
3rd = x-49
401 = 75 +x+ x+ +x-49
401 = 75+3x-49
401 = 3x+26
375=3x
x=375/3 = 125
1st = 125+75 = 200
2nd = 125
3rd = 125-49 = 76
200 + 125 +76 = 401

What is the solution to the compound inequality in interval notation? 2(x+3)>6 or 2x+3≤−7
Answer: The required solution in interval notation is [tex](0,\infty)U(-\infty,-5].[/tex]
Step-by-step explanation: We are given to find the solution to the following compound inequality in interval notation :
[tex]2(x+3)>6~or~2x+3\leq -7~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
To find the solution to (i), we must solve both the parts separately.
The inequality (i) can be solved as follows :
[tex]2(x+3)>6\\\\\Rightarrow x+3>\dfrac{6}{2}\\\\\Rightarrow x+3>3\\\\\Rightarrow x>3-3\\\\\Rightarrow x>0\\\\\Rightarrow x\epsilon (0,\infty)[/tex]
or
[tex]2x+3\leq-7\\\\\Rightarrow 2x\leq-7-3\\\\\Rightarrow 2x\leq -10\\\\\Rightarrow x\leq -\dfrac{10}{2}\\\\\Rightarrow x\leq-5\\\\\Rightarrow x\epsilon(-\infty,-5].[/tex]
Thus, the required solution in interval notation is [tex](0,\infty)U(-\infty,-5].[/tex]

What is the factored form of 6n4 – 24n3 + 18n?
Answer:
Step-by-step explanation:
Notice to facts:
The numbers 6, -4 and 18 have a common factor: 6.In all the terms (n⁴, n³, n) are a factor n.The expression has a common factor 6n. Then,
6n⁴-24n³+18n = 6n(n³-4n²+3).
In order to factor the term n³-4n²+3 we use Ruffini-Horner rule, which gives us that
n³-4n²+3 = (n-1)(n²-3n-3).
Then,
6n⁴-24n³+18n = 6n(n³-4n²+3) = 6n(n-1)(n²-3n-3).

Final answer:
Using the elimination method, we solved the system of linear equations to find that the solution is x = 3 and y = 1/2.
Explanation:
The student is asking us to solve a system of linear equations. The equations given are:
3x + 2y = 10
2x + 3y = 15/2
To solve these equations, we can use either substitution or elimination method. Let's go ahead with the elimination method to find the values of x and y.
Multiply the first equation by 3 and the second equation by 2 to make the coefficients of x the same:
9x + 6y = 30 (multiplying the first equation by 3)
4x + 6y = 15 (multiplying the second equation by 2)
Now, subtract the second equation from the first equation to eliminate y:
9x + 6y - (4x + 6y) = 30 - 15
5x = 15
x = 3
Now plug x=3 into the first original equation:
3(3) + 2y = 10
9 + 2y = 10
2y = 1
y = 1/2
Therefore, the solution to the system of equations is x = 3 and y = 1/2.

A taxi charges $2.50 for the first mile and $0.40 for each mile after that. The expression below shows how to find the total cost, in dollars, of a 20-mile taxi ride. 2.50 + 0.40 (20 - 1) What is the cost of the ride?
Answer:
Step-by-step explanation:
Alright , lets get started.
The first mile charge = [tex]$2.5[/tex]
Total miles taxi covered = [tex]20[/tex]
Subtracting first mile frm the total ride = [tex](20-1)[/tex]
Means the fare will apply on this mile.
So, cost of total ride = [tex]2.5 + 0.4 (20-1)[/tex]
cost of total ride = [tex]2.5+0.4*19[/tex]
cost of total ride = [tex]2.5+7.6[/tex]
cost of total ride = [tex]10.1[/tex]
