The time practiced in the 12 days is an illustration of proportions

The given parameters are:

Days = 12

Proportion = 3/4

So, the number of hours is:

Hours = Days * Proportion

This gives

Hours = 12 *3/4

Hours = 9

Hence, she practices a total of 9 hours in the 12 days

There are 60 minutes in an hour.

So, we have:

Minutes = 9 * 60

Minutes = 540

Hence, she practices a total of 540 minutes in the 12 days

Answer:

Erik uses 8 centimeters of tape to wrap each present.

Step-by-step explanation:

16 centimeters can wrap 2 presents.
24 centimeters can wrap 3 presents.
Add both amounts of tape together to find the total amount of tape used.  Then add the number of presents wrapped together.
16 + 24 = 40 centimeters
2 + 3 = 5 presents
40/5

In order to find how much tape wraps one present, divide both the top and bottom by the denominator (5)
40/5 = 8 centimeters
5/5 = 1 present

Erik uses 8 centimeters of tape to wrap each present.

The total cost of the carpet purchased by the company for its reception is  $767.20.

The first step is to determine the total square feet of carpet that would be bought: 1.40 x 68.5 = 95.9 square feet

Now, determine the total cost of the carpet. This can be known by multiplyig the cost per square foot by the total amount of carpet needed.

95.9 x 8 = $767.20

Answer:

[tex]59 + 30c \leq 125[/tex]

2 rooms

Step-by-step explanation:

Given

[tex]Base\ Amount = \$59[/tex]

[tex]Additional = \$30[/tex] per carpet

[tex]Customer\ Budget = \$125[/tex]

Required

Write an inequality to determine the situation

Represent the number of carpets with c

First, we need to determine an expression for the cleaner's charges:

This is:

[tex]59 + 30 * c[/tex]

[tex]59 + 30c[/tex]

Since the customer's budget do not exceed $125.

This implies that the cleaner's charges must be less than or equal to the budget.

So, we have:

[tex]59 + 30c \leq 125[/tex]

Solving further: [Collect Like Terms]

[tex]30c \leq 125 - 59\\[/tex]

[tex]30c \leq 66[/tex]

Divide through by 30

[tex]c \leq 66/30[/tex]

[tex]c \leq 2.2[/tex]

Since number of rooms can't be fraction;

The maximum number of rooms the customer can afford is 2

No sé exactamente de qué se trata el ejercicio, hay muchas respuestas posibles

Step-by-step explanation:

Step-by-step explanation:

That is, the event A ∪ B will occur if either A or B occurs. In Example 4.1(a), if A = {g} is the event that the child is a girl and B = {b} is the event that it is a boy, then A ∪ B = {g, b}.

Associative law: (E ∪ F)∪G = E ∪ (F ∪ G)

Distributive law: (E∪F)G=EG∪FG

Commutative law: E ∪ F = F ∪ E

Answer: Below

Step-by-step explanation:

Using the information, we can see that they all refer to Elena as a marker for how much they walked, directly or indirectly.

Let's use E for Elena, J for Jada, and L for Lin.

E + 4 = J

E + 6 = L

E = E

We know they all walked a total of 37 miles.

J + L + E = 37

(E + 4) + (E + 6) + E = 37

Simplify.

3E + 10 = 37

3E = 27

E = 9

Using E is 9, we find that:

Elena walked 9 miles

Lin walked 15 miles

Jana walked 13 miles

13 + 15 + 9 = 37, so our answer checks out.

We know that:

Add 4 both sides

Changing "Jada + Jada + Jada" to "3(Jada)"

Subtracting 2 both sides:

Divide 3 both sides:

Substituting the miles Jada walked into the equation "Jada = 4 + Elena"

Subtract 4 both sides:

Substituting the miles Jada walked into the equation "Lin = 2 + Jada"

Answer: [tex]3\frac{7}{10}[/tex] or [tex]\frac{37}{10}[/tex]

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below. Follow these steps I made for you.

Step 1: Convert [tex]8\frac{4}{5}[/tex] to an improper fraction. Use this rule: [tex]a\frac{b}{c} = \frac{ac + b}{c}[/tex].

[tex]\frac{8 * 5 + 4}{5} - 5\frac{1}{10}[/tex]

Step 2: Simplify 8 × 5 to 40.

[tex]\frac{40 + 4}{5} - 5\frac{1}{10}[/tex]

Step 3: Simplify 40 + 4 to 44.

[tex]\frac{44}{5} - 5\frac{1}{10}[/tex]

Step 4: Convert [tex]5\frac{1}{10}[/tex] to an improper fraction. Use this rule [tex]a\frac{b}{c} = \frac{ac + b}{c}[/tex].

[tex]\frac{44}{5} - \frac{50 * 10 + 1}{10}[/tex]

Step 5: Simplify 5 × 10 to 50.

[tex]\frac{44}{5} - \frac{50 + 1}{10}[/tex]

Step 6: Simplify 50 + 1 to 51.

[tex]\frac{44}{5} - \frac{51}{10}[/tex]

Step 7: Find the Least Common Denominator (LCD) of [tex]\frac{44}{5}, \frac{51}{10}[/tex]. In other words, find the Least Common Multiple (LCM) of 5, 10.

LCD = 10

Step 8: Make the denominators the same as the LCD.

[tex]\frac{44 * 2}{5 * 2} - \frac{51}{10}[/tex]

Step 9: Simplify. Denominators are now the same.

[tex]\frac{88}{10} - \frac{51}{10}[/tex]

Step 10: Join the denominators.

[tex]\frac{88- 51}{10}[/tex]

Step 11: Simplify.

[tex]\frac{37}{10}[/tex]

Step 12: Convert to a mixed fraction.

Answer: Use the distance formula to find the length of each side, and then add the lengths.

Step-by-step explanation:

To find the perimeter of this quadrilateral with known vertices: Use the distance formula to find the length of each side, and then add the lengths.

The distance between two points is the length of the line joining the two points. Distance is a numerical or occasionally qualitative measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria.

Here, we have,

Mathematically, the distance between points on a coordinate plane is given by this formula:

Formula: distance= √(x_2-x_1)²+(y_2-y_1)²

Where:

x and y are the vertices (points) on a coordinate plane.

Therefore, when the distance formula has been used to determine the length of of each side of the quadrilateral. You should then add the lengths of each side together.

Ratio is [tex]2\dfrac{1}{4}:6\dfrac{3}{4}[/tex]

To find:

Convert this ratio to a unit rate.

Solution:

We have,

[tex]2\dfrac{1}{4}:6\dfrac{3}{4}=\dfrac{2\times 4+1}{4}:\dfrac{6\times 4+3}{4}[/tex]

[tex]2\dfrac{1}{4}:6\dfrac{3}{4}=\dfrac{8+1}{4}:\dfrac{24+3}{4}[/tex]

[tex]2\dfrac{1}{4}:6\dfrac{3}{4}=\dfrac{9}{4}:\dfrac{27}{4}[/tex]

[tex]2\dfrac{1}{4}:6\dfrac{3}{4}=\dfrac{\dfrac{9}{4}}{\dfrac{27}{4}}[/tex]

[tex]2\dfrac{1}{4}:6\dfrac{3}{4}=\dfrac{9}{27}[/tex]

[tex]2\dfrac{1}{4}:6\dfrac{3}{4}=\dfrac{1}{3}[/tex]

[tex]2\dfrac{1}{4}:6\dfrac{3}{4}=0.333...[/tex]

[tex]2\dfrac{1}{4}:6\dfrac{3}{4}\approx 0.33[/tex]

Therefore, the unit rate is about 0.33.

I guess, the flower bed is a true rectangle, right ?

so, then, the perimeter of that rectangle is

2×length + 2×width = 2×78 + 2×60 = 156 + 120 = 276 in.

1 ft = 12 in

276 in = 23 ft

she can only buy a bundle of 40 ft.

that means she will have

40 - 23 = 17 ft left.
