You've been told fans will be given a free rally towel every 8 games.Also the knicks are going to wear their throwback jerseys every 12 games.If the fans were given a rally towel and the knicks wore their throwback jerseys tonight how many games will it be untill the next time when both happened?
We need to find the lowest common multiple of 8 and 12.
Reminder that the LCM is the lowest number that divides evenly with both of the given numbers.
We can make a chart and see that:
Multiples of 8: 8, 16, 24, 32
Multiples of 12: 12, 24...wait! We have a match with 24!
Therefore, there will be 24 more games until both events will occur.
of 350 male athletes at a high school, some play only basketball, some play on baseball, and some do both. If 250 of the males play basketball, and 120 play both sports, how many of the males play baseball
250 and 120 both adds up to 370 but 350 of the male play sports. So u answer can't be sloved
One hundred male athletes in the school play baseball only. This is determined by subtracting the number of males who play both sports and who play only basketball from the total number of male athletes.
Explanation:The question states there are 350 male athletes in total at the high school. We know that 250 males play basketball and that 120 males play both sports. To figure out the amount of males who play baseball, we first subtract the number of males who play basketball and both sports from the total number of male athletes.
Therefore, the calculation would be as follows:
First, subtract the number of students who play both sports (120) from the number of students who play basketball (250). This gives you the number of students who only play basketball. 250 - 120 = 130. Then subtract the number of students who only play basketball (130) and the number of students who play both sports (120) from the total number of male athletes (350) to get the number of students who only play baseball. 350 - 130 - 120 = 100.
So, there are 100 males that only play baseball according to the given information.

Step-by-step explanation:
it is possible to create a semi regular tessellation using only squares and regular hexagons?
Final answer:
Yes, a semi-regular tessellation can be created using squares and regular hexagons. One example of this is the honeycomb pattern, which consists of hexagons surrounded by squares.
Explanation:
Yes, it is possible to create a semi-regular tessellation using only squares and regular hexagons. A semi-regular tessellation is a pattern that repeats using two or more regular polygons, but with different arrangements around each vertex.
One example of a semi-regular tessellation using squares and regular hexagons is the honeycomb pattern. In this pattern, the squares and hexagons are arranged in such a way that they fill the plane without any gaps or overlaps.
To create the honeycomb pattern, you start by placing a regular hexagon in the center. Then, surround the hexagon with six squares, with each square touching two sides of the hexagon. Finally, place a hexagon on each side of the square, with each hexagon touching two sides of the square and one side of the adjacent hexagon. Repeat this pattern to create a tessellation.

An explicit formula is used to find any term in a sequence by putting in the number of that term in place of the unknown variable.
In order to find the first four terms, we need to plug values, from 1-4, separately in each of the formulas.
For f(n) = 7(n+1) - 11, put values from 1-4 in place of n:
f(1) = 7(1+1) - 11 = 3 ----> First term
f(2) = 7(2+1) - 11 = 10 ----> Second term
f(3) = 7(3+1) - 11 = 17 ----> Third term
f(4) = 7(4+1) - 11 = 24 ----> Fourth term
For f(n) = 65 - 10n, put values from 1-4 in place of n:
f(1) = 65 - 10(1) = 55 ----> First term
f(2) = 65 - 10(2) = 45 ----> Second term
f(3) = 65 - 10(3) = 35 ----> Third term
f(4) = 65 - 10(4) = 25 ----> Fourth term

A fish tank that holds 80 gallons of water is 55 % full. how many gallons are in the tank now?
Answer:
[tex]44\ gallons[/tex]
Step-by-step explanation:
we know that
A fish tank holds [tex]80[/tex] gallons of water
so
By proportion
Find how many gallons represent [tex]55\%[/tex] of the total tank capacity.
[tex]\frac{80}{100}\frac{gallons}{\%} = \frac{x}{55}\frac{gallons}{\%}\\ \\x=55*80/100\\x= 44\ gallons[/tex]
There are 44 gallons of water in the tank. This is calculated by converting the percentage full into a decimal (0.55) and multiplying it by the total capacity of the tank (80 gallons).
Explanation:The question is asking how many gallons are currently in the fish tank that is 55% full and has a total capacity of 80 gallons.
First, you need to convert the percentage of the tank that is full (55%) to a decimal. To do this, you divide the percentage by 100.
So, 55 divided by 100 equals 0.55.
Next, you multiply this decimal by the total capacity of the tank to find out how many gallons are currently in the tank. 0.55 times 80 equals 44. Therefore, there are 44 gallons of water in the fish tank now.

find the slope 3x+5y=29
Answer: [tex]-\frac{3}{5}[/tex]
Step-by-step explanation:
If you solve for y, then it will be in y = mx + b format where m is the slope.
3x + 5y = 29
-3x -3x
5y = -3x + 29
[tex]\frac{5y}{5} = \frac{-3x}{5} + \frac{29}{5}[/tex]
[tex]y = \frac{-3}{5}x + \frac{29}{5}[/tex]
m = [tex]-\frac{3}{5}[/tex]
To find the slope of the line for the equation 3x+5y=29, rewrite it in slope-intercept form y=mx+b. After isolating y, you'll find that the slope m is -3/5.
Explanation:To find the slope of the line represented by the equation 3x + 5y = 29, we need to rewrite the equation in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
First, we solve for y:
Subtract 3x from both sides to get 5y = -3x + 29.Divide every term by 5 to isolate y on one side, resulting in y = -3/5x + 29/5.Now, the equation is in slope-intercept form, and we can easily identify the slope as -3/5. This means there is a decrease of 3 on the vertical axis for every increase of 5 on the horizontal axis. Thus, the slope of the line is -3/5.
Dion is at a basketball game and he wants to buy some hamburgers and drinks. His friend joe brought 2 Hamburgers and 5 drinks for $8.00 and Felicia brought 2 hamburgers and 3 drinks for $6.00. Help Dion determine the cost of one hamburger and one drink
For this one, the best way to do it is write out you formulas, then solve for the first one and see if it works for the second one.
I am going to use h for hamburgers and d for drinks to make it easier.
2h+5d=8
2h+3d=6
So what I did was make the drinks 1, this way you can see if you need to raise it or if the hamburgers could come out even. When you do that here is what it looks like:
2h+5(1)=8
2h+5=8
2h=3
h=1.50
So here is what you have as of now
h= 1.50 and d= 1
now plug that into the next problem
2h+3d=6
2(1.50)+3(1)=6
3+3=6
So that is your answer
Hamburgers are $1.50
and Drinks are $1
Hope this helps!
Hamburgers cost 1.50 each and its 1.00 for each drink
At a school concert,the orchestra plays 8 songs that are 4.25 min long and 3 songs that are twice as long as each of the others.how long is the concert?
Answer: 59.5 minutes.
Step-by-step explanation:
1. You have the following information given in the problem above:
- 8 songs are 4.25 minutes long.
- 3 songs are twice as long as each of the others.
2. Therefore, the total time of 8 songs is:
[tex](8)(4.25min)=34min[/tex]
3. And the total time of the 3 songs is:
[tex](2)(3)(4.25min)=25.5min[/tex]
4. Therefore, you have that the result is:
[tex]34min+25.5min=59.5min[/tex]
The concert is 59.5 minutes long.
Let's break down the problem step-by-step:
The orchestra plays 8 songs that are each 4.25 minutes long.The orchestra also plays 3 songs that are twice as long as each of the 4.25 minute songs.First, we calculate the total time for the 8 songs:8 songs x 4.25 minutes = 34 minutes
Next, we calculate the length of the songs that are twice as long as the 4.25 minute songs:2 x 4.25 minutes = 8.5 minutes per song
We then find the total time for these 3 songs:3 songs x 8.5 minutes = 25.5 minutes
Finally, we add the time for all the songs to get the total duration of the concert:34 minutes + 25.5 minutes = 59.5 minutes
So, the total duration of the concert is 59.5 minutes.
