Hello can you help me please?)

To determine the fraction of the floor covered, we multiply the fraction of the length covered (3/4) by the fraction of the width covered (3/5), resulting in a covered area of 9/20 of the floor space.

To find the fraction of the floor that has been covered by tile, we need to multiply the fraction of the length covered by the fraction of the width covered. If an area of 3/4 of the length and 3/5 of the width is covered, then we perform the multiplication: (3/4) x (3/5) = 9/20.

This means that the fraction of the floor covered with tile is 9/20. This fraction represents the percentage of the entire floor that is tiled, which in this case indicates that less than half of the room is covered because 9/20 is less than 1/2.

Answer:

y + 6 = (x -3)^2

Step-by-step explanation:

Let's use the general form of the vertex equation of a quadratic:  y - k = a(x - h)^2.

Subst. 10 for y, 7 for x, -6 for k and 3 for h.  Then, 10 + 6 = a(7 - 3)^2, or

16 = a(4)^2, or 16 = a(16).  Thus, a = 1, and the equation of this particular parabola is:

y + 6 = (x -3)^2

Given a quadratic function with a vertex at (3,-6) and a point (7,10), by substituting the values into the equation, we find that another point on the graph is (4,-5).

The vertex form of a quadratic function is [tex]\(y = a(x - h)^2 + k\)[/tex], where (h, k) is the vertex of the parabola. In this case, the vertex is (3, -6), so the equation is [tex]\(y = a(x - 3)^2 - 6\).[/tex]

You're also given a point on the graph, which is (7, 10). You can use this point to find the value of a.

Substitute the point's coordinates into the equation and solve for a:

[tex]\(10 = a(7 - 3)^2 - 6\)[/tex]

[tex]\(10 = a(4^2) - 6\)[/tex]

10 = 16a - 6

Now, isolate a:

16a = 10 + 6

16a = 16

a = 1

Now that you know a = 1, you can use this information to find another point on the graph. Simply plug in a different value for x into the equation. Let's choose x = 4 for example:

[tex]\(y = 1(4 - 3)^2 - 6\)[/tex]

y = 1(1) - 6

y = 1 - 6

y = -5

So, another point on the graph is (4, -5).

Answer:

1.  ∠9 = 115°

2.  ∠10 = 65°

3.  ∠8 = 70°

4.  ∠3 = 70°

5. ∠4 = 110°

6. ∠11 = 70°

7. ∠5 = 65°

8. ∠14 = 115°

Step-by-step explanation:

Given that, two parallel lines and two transversal lines.

also given that, ∠1 = 115°   &    ∠12 = 110°

We know that, straight angle  = 180°

∠1 + ∠2 = 180°

∠2 = 180 - 115

∠2 = 65°

∠2 & ∠5 are vertical angles. So, they are same

∠2 = ∠5

∠5 = 65°

Similarly, ∠1 = ∠6 (vertical angles)

∠6 = 110°

Now given that, ∠12 = 110°

∠11 + ∠12 = 180°

∠11  = 180 -110

∠11 = 70°

∠11  &  ∠16 are vertical angles.

∠11  = 16

∠16 = 70°

∠12   =   ∠15  (vertical angle)

∠15  = 110°

∠4  & 12 are Corresponding Angles

∠12  = ∠4

∠4 = 110°

∠3 = 180 - ∠4 = 180 - 110

∠3 = 70°

∠7 = ∠4   (vertical angle)

∠7 = 110°

∠3 = ∠8 (vertical angle)

∠8 = 70°

∠1 = ∠9    (Corresponding Angles )

∠9 = 115°

∠10 = ∠2  (Corresponding Angles )

∠10 = 65°

∠13 = ∠10  (vertical angle)

∠13 = 65°

∠14 = ∠9  (vertical angle)

∠14 = 115°

9.  ∠7 and ∠2  no relation between them.

10. ∠6 and ∠14  are corresponding angles.

The vertical angles theorem states that vertical angles are congruent to each other. Since angles E and F are vertical angles, this means you can make them equal to each other in an equation.

m∠E = m∠F

17x + 1 = 20x - 14

Subtract 20x from both sides.

-3x + 1 = -14

Subtract 1 from both sides.

-3x = -15

Divide both sides by -3.

x = 5

Substitute 5 for x in m∠F (20x - 14).

20(5) - 14 = 86

m∠F = 86°

DaMontre practiced for 60 minutes after taking a total of 1,870 shots, with an initial 70 shots before practice and 30 shots per minute during practice.

The question asks how long DaMontre practiced basketball if he took a total of 1,870 shots, with a pre-practice session of 70 shots, and during practice, he takes 30 shots a minute.

Step-by-step solution:

First, subtract the extra shots DaMontre took before practice from the total number of shots to find out how many shots were taken during practice. So, 1,870 - 70 = 1,800 shots during practice.

Thus, DaMontre practiced for 60 minutes, which is the answer to the question.

Answer: There is 12% of last semester's college costs was spent on books.

Step-by-step explanation:

Since we have given that

Amount spent at her community college = $2300

Amount spent of that on books = $276

We need to find the percent of last semester's college costs was spent on books is given by

[tex]\dfrac{276}{2300}\times 100\\\\=\dfrac{27600}{23}\\\\=12\%[/tex]

Hence, there is 12% of last semester's college costs was spent on books.

The student spent 12% of last semester's college costs on books.

To find the percentage of last semester's college costs that was spent on books, you can use the following formula:

Percentage = (Part / Whole) * 100

In this case:

The "Part" is the amount spent on books, which is $276.

The "Whole" is the total college cost for last semester, which is $2300.

Percentage = ($276 / $2300) * 100

Percentage = (0.12) * 100

Percentage = 12%

So, the student spent 12% of last semester's college costs on books.

Step-by-step explanation:

assign the amount of weeks to x. then we write the equation 160+3x=195-2x which is 7

The equation that can be used to find the number of weeks it will take them to weigh the same amount is 160 + 3w = 195 - 2w , and it will take them 7 weeks to weigh the same amount.

Let's take w as the weight,

Nick's weight after w weeks: 160 + 3w

Adam's weight after w weeks: 195 - 2w

Since they will weigh the same after w weeks, you can set up the equation:

160 + 3w = 195 - 2w

Now, solve for w:

Combine like terms:

3w + 2w = 195 - 160

5w = 35

Divide both sides by 5 to isolate w:

w = 35 / 5

w = 7

So, it will take them 7 weeks to weigh the same amount.

The equation to determine the weight of each of Carl's checked bags is 2w + 4 = 35. After solving, we find that each checked bag weighs 15.5 kg.

To solve the problem regarding Carl's baggage weight, we set up an equation. Carl has two checked bags of equal weight, let's call the weight of each bag w kilograms. He also has a backpack weighing 4 kg. According to the problem, the total weight of all his baggage is 35 kg. We can represent this situation with the following equation:

2w + 4 = 35

This equation adds the weight of the two checked bags (2w since there are two of them and they are equal in weight) and the 4 kg backpack to get the total weight of 35 kg. To find the weight of each checked bag, we can simply subtract the weight of the backpack from the total weight and then divide by two:

Therefore, the weight of each of Carl's checked bags is 15.5 kg.

35 and a 1/2 weeks

36 weeks to have the full amount needed

Answer:

36th weeks

Step-by-step explanation:

Kelsey has saved $35 to buy a video game worth $390.

She plans to save additional $10 per week.

Let w represents number of week.

Let s represents total saving in w weeks.

Addition saving per week = $10

In w weeks saving  = 10w

Previous saving amount = $35

Total saving in w week, s = 35 + 10w

Expression which represents total saving in w weeks

s = 35 + 10w

Now find number of weeks to save $390

So, put s=390 and solve for w

35 + 10w = 390

        10w = 390 - 35

           w = 355÷10

          w = 35.5

Hence, Kelsey will save $390 in 36th weeks.
