lunch, Heather eats a jelly sandwich every 5th day and drinks milk every 4th day. If she had a jelly sandwich and milk today, how many days will pass before she will have both again?
The least common multiple of 4 and 5 is 20, so Heather will have both a jelly sandwich and milk again on the 20th day from today.
The question asks us to determine how many days will pass before Heather will again have both a jelly sandwich and milk if she eats a jelly sandwich every 5th day and drinks milk every 4th day. To find when these two events will coincide again, we need to find the least common multiple (LCM) of the two numbers representing the days on which these events occur.
We find that the,
LCM of 4 and 5 is 20.
Therefore, Heather will have both a jelly sandwich and milk on the 20th day from today. This is because 20 is the smallest number that is a multiple of both 4 and 5, which means it is the first day where both schedules will align again.

if the movie theater seats 328 people, what is the maximum amount of money the theater can bring?
328*12= 3936
$3936.00
The total money a theater can bring in is calculated by multiplying the number of seats by the price of a ticket. Without knowing the ticket price, a specific answer cannot be provided.
Explanation:To determine the maximum amount of money the movie theater can bring in, we need to know the price of a single ticket. For example, if each ticket costs $10, then the total amount of money possible would be 328 multiplied by $10 which equates to $3280. However, without knowing the cost of a ticket, we cannot give a specific answer.

Matt is repairing a gate and needs to nail a brace diagonally to strengthen the posts. If the hieght of the post is 48 inches and there is 64 inches between posts, in inches, what should the length of the diagonal brace be on order to fit between the posts?
(a) 80 inches
(b) 42 inches
(c) 15 inches
(4) inches
We have to realize that the height of a post and the horizontal distance between the posts form a right angle. Then the diagonal that joins the highest point of a post and the lowest point of the other post is the hypotenuse of a right triangle. Then we can apply the Pythagorean theorem to calculate the length of this hypotenuse.
According to the Pythagorean theorem H² = P² + D² where H is the hypotenuse (diagonal) and P the height of a post (cathetus) and D the distance between posts (cathetus).
Since we know these values, we can replace them :
H² = (48inches)² + (64inches)² = 2,304inches² + 4,096inches² = 6,400inches²
H = [tex]\sqrt{6400inches^{2}}[/tex] = 80inches
Answer : (a) 80 inches

The length of the diagonal brace should be 80 inches.
Explanation:To find the length of the diagonal brace, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In this case, the height of the post and the length between the two posts are the two sides of the right triangle. We can use the equation 48^2 + 64^2 = c^2, where c represents the length of the diagonal brace. Solving for c gives us c = sqrt(48^2 + 64^2) = 80 inches. Therefore, the length of the diagonal brace should be 80 inches.

Write the equation of the line that passes through the points (-1,2) and (6,3) in slope intercept form
Answer:
[tex]y =\frac{x}{7} +\frac{15}{7}[/tex]
Step-by-step explanation:
Given that the line passes through two points (-1,2) and (6,3)
Slope of the line passing through (x1,y1) and (x2,y2) is
[tex]\frac{y2-y1}{x2-x1}[/tex]
Hence slope of our line =
(3-2)/(6+1) = 1/7
So in slope intercept form the equation would be
y = 1/7 x +C
to find C
Since (-1,2) lies on the line substitute these in the line equation
2 = 1/7(-1)+c
C = 2+1/7 = 15/7
Hence equation in slope intercept form is
[tex]y =\frac{x}{7} +\frac{15}{7}[/tex]
The equation of the line that passes through the points (-1,2) and (6,3) in slope intercept form is y = 1/7x + 15/7.
Explanation:The question is asking for the equation of a line passing through two given points in slope-intercept form. The slope-intercept form of a linear equation is y = mx + b, where m represents the slope of the line and b is the y-intercept.
Firstly, to find the slope (m), you use the formula: m = (y2 - y1)/(x2 - x1). Substituting the given points into this formula: m = (3 - 2) / (6 - (-1)) = 1/7. Thus, the slope of the line is 1/7.
To then find the y-intercept (b), we substitute the slope and one of the points into the equation: 2 = 1/7 * (-1) + b. Solving for b, we find that b = 2 + 1/7 = 15/7.
So, the equation of the line that passes through the points (-1,2) and (6,3) in slope-intercept form is y = 1/7x + 15/7.

Question 2 need to do a ratio table
Answer: It would take Tanya 15 minutes to run 2 kilometers
Answer: 15 minutes
Step-by-step explanation: This is true because:
If Tanya can run 8 kilometers in an hour (60 minutes) and you need to find how long it takes for her to run 2 kilometers there are two ways you can solve this:
#1: You find the unit rate (how long it takes Tanya to run 1 kilometer).
This would be written as 8 kilometers divided by 60 minutes. Once you do that math, you should get 7 1/2 minutes for one kilometer. However, since she is running 2 kilometers, you would multiply 7 1/2 by 2 to get your answer, which is 15 minutes.
#2: You set up a proportion to solve this problem:
This would be written as:
8/60 == 2/x, where the numerator of each fraction is the number of kilometers ran, the denominator is how long it took to run that distance, and x is the amount of minutes it took Tanya to run 2 kilometers. If you cross multiplied, you would get the following equation:
8x=120.
To get x by itself, you would divide both sides by 8; 8x/8 is x, and 120/8 is 15, getting you an answer of x=15, or 15 minutes.

At a butcher shop, Hilda bought 4 17/20 lb of Beef and some pork. She left with 19 24/25 lb of meat. Express the number of pounds of pork she bought using a decimal
so Hilda bought ? lb of pork
SOMEONE HELP ME ON THIS ONE
Hilda bought 15.11 pounds of pork by subtracting the weight of the beef (4.85 pounds) from the total weight of meat she left with (19.96 pounds).
Explanation:To determine how many pounds of pork Hilda bought, we need to subtract the weight of the beef from the total weight of the meat she left with. First, convert the fractions to decimals. The weight of the beef is 4 17/20 pounds, and 17/20 as a decimal is 0.85, so the beef weight is 4.85 pounds.
The total weight of the meat Hilda left with is 19 24/25 pounds, and 24/25 as a decimal is 0.96, so the total weight is 19.96 pounds.
Next, subtract the weight of the beef from the total weight to find the weight of the pork:
19.96 - 4.85 = 15.11 pounds.
Therefore, Hilda bought 15.11 pounds of pork.
Final answer:
Hilda bought 15.11 lb of pork, found by converting the meat weights to decimals and subtracting the weight of the beef from the total weight of meat she left with.
Explanation:
To find out how many pounds of pork Hilda bought, we need to subtract the weight of the beef she bought from the total weight of the meat she left with. First, we convert the amounts of meat to decimal form for easier subtraction.
Hilda bought 4 17/20 lb of beef. To convert this to a decimal, we divide 17 by 20 and then add it to 4:
17 ÷ 20 = 0.85
4 + 0.85 = 4.85 lb of beef.
Hilda left with 19 24/25 lb of meat in total. To convert this to a decimal, we divide 24 by 25 and add it to 19:
24 ÷ 25 = 0.96
19 + 0.96 = 19.96 lb of meat in total.
To find the weight of the pork, we subtract the weight of the beef from the total weight of the meat:
19.96 lb (total meat) - 4.85 lb (beef) = 15.11 lb of pork.
So, Hilda bought 15.11 lb of pork.

To convert a percent to a decimal, you divide by 100.
60% = 0.60
If x is the unknown number, the word is means equal
84 = 0.60 * x
Divide both sides by 0.60
84/0.60 = (0.60/0.60)* x = x
140 = x
x * .60 = 84
x = 84 / .60
x = 140

In the previous video, you compared the two functions below.
f(x) = 1.2t g(x) = 1.2t-5
What did subtracting 5 in the exponent do to the function? Check all that apply.
It shifts the graph of f left 5 units.
It shifts the graph of f right 5 units.
It multiplies all the y-values by 5.
It divides all the y-values by 5.
It multiplies all the y-values by 1.25.
It divides all the y-values by 1.25.
Answer:
It shifts the graph of f right 5 units. It divides all the y-values by 1.25.Step-by-step explanation:
Subtracting 5 in the exponent of the function g(x) = 1.2t-5 shifts the graph of f(x) right 5 units, and it does not affect the y-values of the function.
Explanation:Subtracting 5 in the exponent of the function g(x) = 1.2t-5 shifts the graph of f(x) right 5 units. This is because the exponent determines the horizontal translation of the function. Adding or subtracting a constant value inside the exponent causes the function to shift right or left, respectively.
Furthermore, subtracting 5 in the exponent does not affect the y-values of the function. It only affects the x-values, specifically their positions on the x-axis.
Therefore, the correct statements are:
It shifts the graph of f right 5 units.It does not multiply or divide the y-values by any factor.What is the value of the discrimination for the quadratic equation -3=-x^2+2x
