Answer:

2 hours to write the story.

1/3 of an hour remaining to complete the story.

20 minutes remaining.

(Read the explanation for further details.)

Step-by-step explanation:

1.Based on the given information, set up an equation;

(1 2/3) hours ; (5/6) story

Convert to improper fractions;

(1 2/3) ; (5/6)

(5/3) ; (5/6)

2. Solve;

(5/3) ; (5/6)

divide both sides by (5/6)

(5/3) ; (5/6)

/(5/6)   /(5/6)

Dividing a fraction is the same as multiplying by its reciprocal

(5/3)/(5/6) ; (5/3)/(5/3)

(5/3)*(6/5) ; (5/3)*(3/5)

2 ; 1

2 hours; 1 story

3. Solve for the time remaining;

Subtract the amount of time elapsed from that total amount of time

total time - time used

2 hours - 1 2/3 hours

Convert to improper fractions

2 - 5/3

1/3 hour

Convert to minutes

20 minutes

Answer:

The graphs below show the cost y of buying x pounds of fruit. One graph shows the cost of buying x pounds of peaches, and the other shows the cost of buying x pounds of plums.

Which kind of fruit costs more per pound? Explain.

Bananas cost less per pound than peaches or plums. Draw a line alongside the other graphs that might represent the cost y of buying x pounds of bananas.

IM Commentary

This task allows students to reason about the relative costs per pound of the two fruits without actually knowing what the costs are. Students who find this difficult may add a scale to the graph and reason about the meanings of the ordered pairs. Comparing the two approaches in a class discussion can be a profitable way to help students make sense of slope.

Solutions

Solution: Slope as Unit Rate

The graph that represents the cost of x pounds of peaches is steeper, so it must have a larger slope. The slope can be interpreted as the unit rate; in this case it tells you the cost of a single pound of fruit.

Since the slope for the peach graph is greater than the slope of the plum graph, the cost of a pound of peaches is greater than the cost of a pound of plums.

For b, students should realize that the cost per pound of bananas will be represented by a slope that is less than either of the other two, and draw a line through the origin labeled "Bananas" and lying below both of the other graphs.

Solution: Adding a scale to the graph

Students who prefer to work with specific numbers can approach this problem by sketching in a scale on the x-axis and y-axis. For example, if they decided that a pound of peaches might cost a dollar, then they might plot the point (1,1) on the line labeled "Peaches", then fill out the rest of the scale accordingly. They could then read off the cost of a pound of plums and see that it is less than for peaches.

For the second question, they could choose any price per pound b for bananas that is less than the one they read off for plums, and then draw a line from the origin through the point (b, 1), and label it "Bananas".

Answer:

Step-by-step explanation:

1. Write the question.

g(n) = n² + 2; Find g(3)​

2. Find and input the numbers into the equation

g(3) =  3² + 2

3² = 9

3. Solve the equation

g(3) = 3² + 2

= 9 + 2

= 11

The answer is 11.

Answer:

No, because the expression s/4 - 16. In the word formed she times 4 and the letter, she should have to dived it.

Step-by-step explanation:

No, because the expression s/4 - 16. In the word formed she times 4 and the letter, she should have to dived it.

Answer:

No, Jerome’s scenario does not match the expression. The term s

4

means the number of songs is divided by four, but the scenario uses the word ‘times,’ which means multiplication. The scenario should say ‘16 fewer than one-fourth the number of songs.

The value of the ratio  1/2: 3  is 1/6

A ratio is a comparison of two things or two quantities. It is the relative size of two quantities expressed as the quotient of one divided by the other.

We need to find the value of 1/2 : 3

This can be written as 1/2 : 3/1

On further simplification, this can be wriiten as

1/2 x 1/3

which is equal to 1/6

This can be written in the form of ratio as 1 : 6

Therefore, the value of the ratio 1/2: 3  is 1/6

Answer:

The correct linear equation is;

f(x) = 10x + 8

Step-by-step explanation:

To choose the correct linear function, we just need to take a specific point, then substitute in each of the equations given to get the one right

The correct one will be the one in which when the x-value is substituted, we will get the y-value

Let us pick (1,18)

Let us begin testing;

A. f(x) = 10x + 8

f(1) = 10(1) + 8 = 10 + 8 = 18

Let us use another point to test this

The second point is (1.5,23)

f(1.5) = 10(1.5) + 8

= 15 + 8 = 23

Answer:

The equation that represents the total cost in dollars is C = 100p + 300

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

∵ Avery must pay a daily fixed cost to  rent the building and equipment

∴ There is a fixed amount b

∵ She pays a cost per phone produced for  materials and labor

∴ There is a rate m

∵ C represents the total cost of producing p phones in dollars

→ Form the linear equation for the situation

∴ The equation is C = m p + b

∵ The labor and materials cost $100 for each phone

∴ m = 100

→ Substitute it in the equation above

∴ C = 100p + b

∵ The cost of producing 3 phones in a day would be $600

∴ p = 3 and C = 600

→ Substitute them in the equation above to find b

∵ 600 = 100(3) + b

∴ 600 = 300 + b

→ Subtract 300 from both sides to find b

∵ 600 - 300 = 300 - 300 + b

∴ 300 = b

→ Substitute it in the equation

∴ C = 100p + 300

∴ The equation that represents the total cost in dollars is C = 100p + 300

Answer:

Step-by-step explanation:

Given the expression a = 3/b

as the denominator of the of the expression b increases the value of the output is known to be decreasing. if the value of b now goes so large to become an infinite, value then the value of a will goes to zero as shown;

If b = ∞

a = 3/∞

a = 0

Note that for any constant value a, the ratio a/∞ will always tends to zero

Answer:

The perimeter of triangle XYZ is 54 cm

Step-by-step explanation:

∵ Δ ABC is similar to Δ XYZ

∵ The longest side in Δ XYZ is 25.2 cm

→ That means its corresponding side in Δ ABC is the longest side

∵ AB = 18 cm, BC = 30 cm, CA = 42 cm

∴ The longest side in Δ ABC is CA

∴ CA is the corresponding side of the side of length 25.2 cm

∴ The ratio of similarity = [tex]\frac{25.2}{42}[/tex] = 0.6 ⇒ (r)

∵ The perimeter of Δ ABC = AB + BC + CA

∴ The perimeter of Δ ABC = 18 + 30 + 42

∴ The perimeter of Δ ABC = 90 cm

→ Use the 2nd fact above

∵ P of Δ XYZ = r × P of Δ ABC

∵ r = 0.6 and P of Δ ABC = 90

∴ The perimeter of Δ XYZ = 0.6 × 90

∴ The perimeter of Δ XYZ = 54 cm

x^4 - 6x^2 - 27

Let u = x^2

We know that x^4 = (x^2)^2.

u^2 - 6u - 27

(u - 9)(u + 3)

Now, back-substitite for u.

(x^2 - 9)(x^2 + 3)

The RIGHT SIDE FACTOR is the difference of two squares.

So, x^2 - 9 becomes (x - 3)(x + 3).

(x - 3)(x + 3)^2

Done.
