Joanne slices a large banana bread into pieces 16 There are 6 adults and 6 children who get a piece of banana bread. The rest of the pieces will be donated to the homeless. What fraction of the banana bread will be​ donated?

Answers

The most appropriate choice for fraction will be given by

Fraction of banana bread will be donated to the homeless is [tex]\frac{1}{4}[/tex]

What is a fraction?

Suppose there is a collection of objects and some part of the objects are taken from the collection. The part which has been taken is called fraction. In other words, part of a whole is called fraction.

The upper part of the fraction is called numerator and the lower part of the fraction is called denominator.

Here,

Total number of banana breads 16

Number of adults who got banana bread = 6

Number of Children who got banana bread = 6

Total number of children and adult who got banana bread = 6 + 6 = 12

Number of banana breads given to the homeless = 16 - 12 = 4

Fraction of banana bread given to the homeless = [tex]\frac{4}{16}[/tex]

                                                                                 = [tex]\frac{1}{4}[/tex]

Answers

The equation of the line is y = -400x + 800

What are linear equations?

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

How to determine the equation that represents the amount of grain?

The given parameters are

Initial number of gallon, c = 800

Constant rate, m = -400 gallons per hour

This means that

Slope = -400

y-intercept = 800

A linear equation is represented as

y = slope * x + y-intercept

i.e.

y = mx + c

So, we have

y = -400x + 800

Hence. the equation of the amount of grain is y = -400x + 800

Mayerlin is deciding between two different movie streaming sites to subscribe to. Plan A costs $34 per month plus $2 per movie watched. Plan B costs $8 per month plus $3 per movie watched. Let AA represent the monthly cost of Plan A if Mayerlin watches xx per month, and let BB represent the monthly cost of Plan B if Mayerlin watches xx movies per month. Write an equation for each situation, in terms of x,x, and determine the number of monthly movies watched, x,x, that would make the two plans have an equal monthly cost.

Answers

Considering the definition of an equation and the way to solve it, the number of monthly movies watched that would make the two plans have an equal monthly cost is 26.

Definition of equation

An equation is an algebraic equality in which there are unknowns with unknown value. The unknown represents the number, if any, that makes the equality true. This unknown number is the solution of the equation.

This is, the solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:

When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.

Number of monthly movies watched

Being "x" the number of monthly movies watched, you know that:

Plan A costs $34 per month plus $2 per movie watched. → A= 34 + 2xPlan B costs $8 per month plus $3 per movie watched. → B= 8 + 3x

If the two plans have an equal monthly cost, the equation in this case is:

A= B

34 + 2x= 8 + 3x

Solving:

34 - 8= 3x - 2x

26= x

Finally, 26 monthly movies watched would make the two plans have an equal monthly cost.

These angles are called vertical angles or angles opposite to each other during the intersection of two lines.

Vertical angles are equal to each other, so we can set the expressions equal to each other and solve for x.

Solve for x9x - 4 = 8x + 7              -> Subtract 8xx - 4 = 7                        -> Add 4x = 11

Step-by-step explanation:o convert the decimal 9.57 to a fraction, just follow these steps:

Step 1: Write down the number as a fraction of one:

9.57 = 9.57/ 1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 2 numbers after the decimal point, we multiply both numerator and denominator by 100. So,

(1 × 100)

= 9 57/ 100

the number of women graduating from​ 4-yr colleges in a particular country grew from ​1930, when 48780 women earned a​ bachelor's degree, to ​2003, when approximately 756000 women received such a degree. find an exponential function that fits the​ data, and the exponential growth rate.

Answers

The exponential function which shows the exponential growth rate of graduating women is: A(t) = A₀e∧(0.037t).

What is defined as the Growth Function?When we need to start writing a growth function, we use three separate components. The first component is the starting population, the second is the growth rate, and also the third is the time elapsed. By combining all three, we can create a growth equation that will assist us in determining the growth rate if we are provided with the final population as well as the time elapsed.

The following equation can be used to calculate an exponential function again for number of women graduating from four-year colleges in t years after 1930:

A(t) = A₀e∧(rt)

In which A₀ is the starting point and r is the exponential growth rate expressed as a decimal.

In 1930, 48780 women received a bachelor's degree.

This implies that;

A₀ = 48780

In 2004, approximately 756000  people

The year 2003 is 73 years after 1930, that also means

Using the equation as an example:

A(t) = A₀e∧(rt)

Put the values;

756000 = 48780 e∧(73r)

e∧(73r) = 756000/ 48780

e∧(73r) = 15.49

Taking log both side;

73r = ㏑ 15.49

r = 2.7/7

r = 0.037

The function becomes;

A(t) = A₀e∧(0.037t)

Thus, the exponential function which shows the exponential growth rate of graduating women is: A(t) = A₀e∧(0.037t).
