Answer:
6
Step-by-step explanation:
fred has 2 peanut butter and 3 jelly
type 1 peanut butter can go with all three types of jelly = 3 pb&js where ther is one constant peanutbutter and 3 different jellys
type 2 peanut butter can go with all three jellies = 3 pb&js where there is one constant peanutbutter and 3 different jellies
3+3=6
there are 6 peanut butter and jelly sandwhiches he could make.
you can also just multiply the numbers (2x3=6)
Final answer:
Fred can make 6 different peanut butter and jelly sandwiches by multiplying the number of peanut butter types by the number of jelly types (2 types of peanut butter × 3 types of jelly). The type of bread does not affect the count as there's only one type.
Explanation:
To determine how many different peanut butter and jelly sandwiches Fred can make, we need to consider all possible combinations of peanut butter, jelly, and bread. Since Fred has two types of peanut butter, three types of jelly, and one type of bread, the number of different sandwich combinations can be calculated using the Counting Principle. This principle states that if there are n ways to do one thing, and m ways to do another, then there are n × m ways to do both.
In Fred's case, for every type of peanut butter, he can choose from three different types of jelly. So, for two types of peanut butter, we have:
2 types of peanut butter × 3 types of jelly = 6 combinations
Since there's only one type of bread, it doesn't change the number of combinations.
Therefore, Fred can make 6 different peanut butter and jelly sandwiches.

Two rectangular adjacent rooms share a wall 1‘ x 1‘ tiles cover the floor of each room describe how the greatest possible length of the adjoining wall is related to the total number of tiles in each room
Answer:
Consider two adjacent rectangular rooms having Length=L, and, Breadth = B
Now Suppose the wall which is in between two rooms has a height or length =H.
Breadth of wall = B [ if the wall doesn't exceed the breadth of room]
Considering two rooms to be identical,
Area of each room= L × B square unit
Area of each tile = 1×1=1 square unit
Number of tiles required= L B ÷ 1= LB tiles( product of length and breadth of room is number of tiles required)
Suppose if,LB= N
B= N/L .................(1)
Area of wall(W) = B×H= B H square unit
B =W/H ......................(2)
Equating (1) and (2)
⇒N/L = W/ H
⇒H =[tex]\frac{WL}{N}[/tex]
⇒H =[tex]\frac{WL}{LB}[/tex]
⇒H = W/B
⇒ H =[tex]\frac {\text{ Area of Wall}}{\text{Breadth of room or wall}}[/tex]

A student works no more than 25 hours each week at a part-time job. Write an inequality that represents how many hours the student can work each day. (how do you solve this)
Given that a student works no more than 25 hours per week, and that work is performed every day of a 7-day week, the maximum number of hours they can work per day is approximately 3.57, making it fair to say they can work up to 3 hours each day. This scenario can be represented by the inequality h ≤ 3.
Explanation:To answer your question, we need to find an inequality that represents how many hours the student can work each day given they work no more than 25 hours every week.
If we assume a typical week encompasses 7 days, and the student works every day of the week, then we should distribute the maximum hours worked per week over these seven days.
This results in 25 hours ÷ 7 days ≈ 3.57 hours/day. However, since you can't work a fraction of an hour, the student can work up to 3 hours a day.
The inequality representing this scenario would be h ≤ 3, where 'h' represents the number of hours the student can work each day.

A function is defined as {(0, 1), (2, 3), (5, 8), (7, 2)}. Isaac is asked to create one more ordered pair for the function. Which ordered pair can he add to the set to keep it a function? please help.
1) (0, 2)
2) (1, 3)
3) (5, 3)
4) (7, 0)
Correct answer is option(2).
Isaac can add the ordered pair (1, 3) to the set to keep it a function.
A function is a relation where each input (or domain element) is associated with exactly one output (or range element).
This means that in the set of ordered pairs representing a function, no two pairs can have the same first element (input) but different second elements (outputs).
Given the function defined as : {(0,1),(2,3),(5,8),(7,2)},
we need to add one more ordered pair without violating the property that each input maps to exactly one output.
Let's examine each option:
1.) (0, 2) : This pair has the same first element as (0, 1). Adding (0, 2) would imply that the input 0 maps to both 1 and 2, which is not allowed in a function because each input must map to exactly one output.
2.) (1, 3) : This pair has a first element of 1, which is not present in the original set of ordered pairs. Therefore, adding (1, 3) does not create any conflicts. The input 1 is not repeated, so each input still maps to exactly one output. This maintains the function property.
3.) (5, 3) : This pair has the same first element as (5, 8). Adding (5, 3) would imply that the input 5 maps to both 8 and 3, which violates the definition of a function.
4.) (7, 0) : This pair has the same first element as (7, 2). Adding (7, 0) would imply that the input 7 maps to both 2 and 0, which also violates the definition of a function.
Therfore , Only the pair (1,3) can be added to the set without violating the function property. This pair introduces a new input that does not conflict with the existing inputs in the set.

x + 9 = 18 + -2x
x+9=18+-2x
divide 2x from both sides
which makes it 3x+9=18
subtract 9 from the 18
which is 3x=9
divide 3 from both sides
which gives you x=3
x+9=18+(-2x) add the 2x to the x and you should get 3x+9=18. Then you would subtract the 9 from the 18 and should get 3x=9. Then just divide the 9 by the 3 and get x=3 which is your answer. Hope this helps!
lin measured the diameter of a circle in two different directions. Measuring vertically, she got 3.5 cm, and measuring horizontally, she got 3.6 cm. Explain sone possible reasons why these measurements differ.
Answer:
Diameter of circle while measuring vertically=3.5 cm
Diameter of circle while measuring Horizontally=3.6 cm
As you have not written by which instrument from geometry box you have measured the length of diameter.
1. By Scale i.e ruler 2. By Divider Or 3. By mere Observation i.e by comparing length
1.If you have done measurement by simply observation there are maximum possibility of having error.
2. Then if you have measured these lengths by scale or ruler there is very less chances of getting error in measurement of length because sometimes divison in scale varies i.e if a point lies between 4.5 to 4.6 we can't say exactly whether it is 4.5 or 4.6.
3. So it is better to compare line segments by Divider.There is no chances of getting error.
Most probably you have measured Diameter by ruler, Due to that you have faced the problem.
Answer:
The possible reasons are shown below:
The shape is not a perfect circle as it is difficult to draw a perfect circle.Measurements could be rounded, not exact.It may be possible that the thickness of the circle affected the measurement.The length of vertical measurement is small, so may be she did't measure across the widest part when she is measuring vertically.Step-by-step explanation:
Consider the provided information.

BRAINLIEST ANSWER!! The product of 3, and a number increased by seven, is -36. Translate the equation, then solve.
Product is multiplication.
Let the number = x
3 *( X+7) = -36
Use distributive property:
3x +21 = -36
Subtract 21 from each side:
3x = -57
Divide both sides by 3:
x = -57 /3
x = -19
Check: 3 * (-19 +7) = 3 * -12 = -36

One of the fastest recorded speeds of the elephant is 6.9 m/s. Approximately, what is this speed in kilometers per hour? [1 kilometer = 1,000 meters] [1 hour = 60 minutes = 3,600 seconds]
To answer this question, we know that 1km equals 1000m
and 1 hour is equal to 60 minutes. In the same way 1 minute equals 60 sec onds
So we have to change the units of elephant speed to km per hour.
For this we do the following procedure:
1) we multiply 6.9 m / s by the conversion factor from meters to kilometers (1 km / 1000m)
[tex]6.9 \frac{m}{s} *\frac{1 km}{1000 m}=0.0069\frac{km}{s} \\[/tex]
2) The result obtained is multiplied by the conversion factor from seconds to minutes (60s / 1min)
[tex]0.0069 \frac{km}{s} *\frac{60 s}{1 min}=0.414 \frac{km}{min}\\[/tex]
3) The result obtained is multiplied by the conversion factor from minutes to hours (60min / 1hr)
[tex]0.414\frac{km}{min}*\frac{60 min}{1 h}= 24.84\frac{km}{h} \\[/tex]
The answer is 24.84 km / h
You can skip step 2) multiplying 0.0069 km / s by the conversion factor from seconds to hours (3600 s / 1h)
