Jazmin is completing an art project. She has two pieces of construction paper. The first piece is 4 4 4444 inches wide and the second piece is 3 3 3333 inches wide. Jazmin wants to cut the paper into strips that are equal in width and are as wide as possible. How wide should Jazmin cut each strip?

Answers

Answer:

Each strip should 11 inches wide.

Step-by-step explanation:

We are told that Jazmin has two pieces of construction paper. The first piece is 44 inches wide and the second piece is 33 inches wide. Jazmin wants to cut the paper into strips that are equal in width and are as wide as possible.

To find the greatest possible width of each strip we will find GCF of 44 and 33.

Factors of 44 are: 1, 2, 4, 11, 22, 44.

Factors of 33 are: 1, 3,11, 33.

We can see that 11 is the greatest common factor of 44 and 33 as 11*4=44 and 11*3=33, therefore, Jasmine should cut each strip 11 inches wide.

An airplane flies 105 miles in 1/2 hour. How far can it fly in 1 and 1/4 hours at the same rate of speed?

Answers

First, let's figure out how many miles the plane can fly in 1/4 hour. Since this is half of 1/2 hour, it can fly half of 105 miles, which is 52.5 miles. Next, we need to know how many miles it can fly in one hour. Since it flies 105 miles in 1/2 hour, it flies twice that (210) miles in one hour. So then in 1 and 1/4 hours, it flies 210+52.5 miles.

how to make a percentage a fraction and a decimal

Answers

Say you have 14 out of 100.  To make that into a fraction, you simply put the first number (as long as it says over or out of) on top and the second on bottom.  You can also make that into a decimal, which would be .14 which is also equal to 14%.

Final answer:

To convert a percentage to a fraction, write it with a denominator of 100 and simplify. To make it a decimal, divide by 100. Convert a decimal to a percentage by multiplying by 100, and to a fraction by writing it with the place value as the denominator.

Explanation:

To convert a percentage to a fraction, you express the percentage value as a fraction with a denominator of 100. For instance, to convert 25% to a fraction, you write it as 25/100, which can be simplified to 1/4. When converting a percentage to a decimal, you divide the percentage value by 100. So, 25% as a decimal is 0.25.

To convert a decimal to a percentage, you multiply the decimal by 100 and add the percent symbol (%). For example, the decimal 0.83 would be 83% when converted to a percentage. To make a decimal a fraction, you express it in terms of its place value as a denominator and simplify if possible. For example, 0.83 can be expressed as 83/100 as a fraction.

Calculating percent composition involves using the part-total relationship. If you know the fractional score, you multiply it by 100 to find the percentage score. For instance, if you get 96 out of 100 on a test, you calculate the percentage composition by dividing 96 by 100 to get 0.96, then multiply by 100 to get 96%.

At 5 a.m., the temperature at an airport was −9.4°F . Six hours later, the temperature was 2.8°F . Which expression represents the total temperature change over the six hours?

Answers

Let x = the number of hours since 5 a.m.
Let y = temperature, °F

Let the total temperature change be modeled by the expression
y =  ax + b

At 5 a.m., x = 0 and y = -9.4°F. Therefore
b = -9.4

When x = 6 hours, y = 2.8°F. Therefore
6a + b = 2.8
6a - 9.4 = 2.8
6a = 12.2
a = 2.0333

The expression is
y = 2.0333x - 9.4

Answer:
y = 2.0333x - 9.4
where
x = hours since 5 a.m.
y = temperature, °F

Answer:

|2.8 - (-9.4)|

Step-by-step explanation:

The correct answer is |2.8 - (-9.4)|.

A variable is the letter used as a placeholder for an unknown value, playing a pivotal role in mathematical reasoning and problem-solving processes.

A placeholder for an unknown value in mathematics, algebra, and other fields is typically represented by a variable. Variables are symbols, often letters like x, y, or z, used to denote unspecified or changing quantities.

They serve as placeholders for values that can vary or are yet to be determined within a given context. In algebraic equations, variables enable the representation of relationships between quantities, facilitating problem-solving and mathematical modeling.

By assigning specific values to variables, equations can be solved, functions can be evaluated, and patterns can be analyzed. Variables are fundamental in various mathematical concepts, including equations, inequalities, functions, and formulas, allowing for flexible and dynamic representations of mathematical relationships.

Mia played in two softball games one afternoon. the first game lasted 42 minutes the second game lasted 5/3 times longer than the first game. how long did Mia's second game last?

Answers

1st game was 42 minutes....2nd game was 5/3 times longer....so we multiply

5/3 * 42 = (5 * 42)/3 = 210/3 = 70 minutes....so the 2nd game was 70 minutes or 1 hr and 10 minutes
42 x 5/3= 70
70min= 1hr 10min

A student applies for a summer internship at different companies. Given this student's previous work experience and grades, there is a chance of getting an internship offer at any company. Getting an offer from one company does not affect getting an offer from another company. What is the probability this student will receive or more offers?

Answers

Given that a student applies for a summer internship at 5 different companies. Given this student's previous work experience and grades, there is a 40% chance of getting an internship offer at any company. Getting an offer from one company does not affect getting an offer from another company.

What is the probability this student will receive 2 or more offers? (Round to 3 decimal places.)

This situation describes a binomial distribution with the probability of success = 40% = 0.4 and the number of trials = 5.

P(2 or more offers) = P(2) + P(3) + P(4) + P(5) = 1 - [P(0) + P(1)]

The binomial probability is given by

[tex]\bold{P(x)=\ ^nC_xp^x(1-p)^{(n-x)}} \\ \\ \bold{P(0)}=\ ^5C_0(0.4)^0(1-0.4)^{(5-0)} \\ \\ =1\times1\times(0.6)^5=0.07776 \\ \\ \bold{P(1)}=\ ^5C_1(0.4)^1(1-0.4)^{(5-1)} \\ \\ =5\times0.4\times(0.6)^4=2\times0.1296 \\ \\ =0.2592 \\ \\ \bold{P(0)+P(1)}=0.07776 + 0.2592=0.33696 \\ \\ \bold{\therefore P(2\ or\ more\ offers)}=1-[P(0)+P(1)] \\ \\ =1-0.33696=0.66304[/tex]

Therefore, the probability this student will receive 2 or more offers is 0.663 to 3 decimal places.

how would i solve |-9x|=64

Answers

|-9x| = 64
-9x will become 9x

9x = 64
x = 64/9

the high school lunch menu repeats every 6 school days the middle school lunch menu reapeat every 8 school days on march 5th both school served chicken wraps what is the next calendar date on which both schools will serve chicken wraps

Answers

Hey! Hope that I can help.

To do this, I circled all the dates on the attached calendar, with red = middle and blue = high. The 6th of March in 2018 is when both schools will have chicken wraps again.
Final answer:

To find the next date both schools will serve chicken wraps, we find the least common multiple of the days their menus repeat, which is 24 days. We then count 18 school days (excluding weekends) from March 5th.

Explanation:

This question is about finding the least common multiple (LCM) of 6 and 8, which are the days that the lunch menus repeat for the high and middle schools respectively. The LCM of 6 and 8 is 24. This means that both schools will serve chicken wraps every 24 school days.

Assuming that March 5th falls on a school day, and that the school operates from Monday to Friday with the weekends off, we subtract weekends from this period. In a span of 24 weekdays, there are usually around 6 weekend days (3 weekends). So, from March 5th, we count 18 school days forward (24 days minus 6 weekend days). The result gives us the next day both schools serve chicken wraps.

Which expression represents this word phrase? seven less than the quotient of x and 9 x−7 9 x÷ 9 7 (x÷9)−7 (9÷x)−7

Answers

The expression that represents 'seven less than the quotient of x and 9' is written as (x / 9) - 7, translating the operations of division and subtraction from the word phrase to algebra.

The word phrase 'seven less than the quotient of x and 9' translates to an algebraic expression by identifying the key terms: 'quotient' refers to division, while 'less than' indicates subtraction.

Specifically, the quotient of x and 9 is expressed as (x \/ 9), and to represent 'seven less than' this quotient, we subtract 7 from it. Thus, the corresponding mathematical expression is (x \/ 9) - 7.

2p=kx-t how do you solve for x

Answers

isolate x on one side of the equation. divide by k.
2p over k =x-t
add t
(2p/k)+t = x.
hope this helps and have a wonderful day!
Final answer:

To solve for 'x' in the equation 2p=kx-t, you would first need to isolate 'x' on one side of the equation. Add 't' to both sides to get 2p + t = kx, then divide through by 'k' to solve for 'x'. Hence, x = (2p + t) / k.

Explanation:

To solve the equation 2p=kx-t for x, you would first need to isolate x on one side of the equation. This can be done by adding 't' to both sides of the equation, which results in 2p + t = kx.

Then, to isolate 'x', you would divide both sides of the equation by 'k'. So, the solution for x would be x = (2p + t) / k.

This rearrangement allows you to solve for x in terms of p, t, and k. This is an exercise in algebra, with the goal of isolating the variable you are attempting to solve for, in this case, x.
