There are **60 students **that** prefer soccer**

The first step is to determine the percentage of** students** that **prefer soccer **The percentage of students that **prefer** **soccer** = 100 - (53% + 26% + 15% ) = 6%

6% of the students surveyed prefer **soccer **

Number of** students** that **prefer soccer **= (percentage of students that prefer soccer / 100) x total number of students surveyed

If grapes are 92% water and raisins are 20% water by weight, then how much did a quantity of raisins, which currently weighs 10 pounds, weigh when all the raisins were grapes

10 lbs of raisins contains 20% water by weight, so they contain

0.20 × (10 lbs) = 2 lbs

of water. This means the non-water portion of the raisins weighs 8 lbs. This weight stays the same throughout the drying process.

As grapes, they had a total weight of

8 lbs + *w*

where *w* is the water weight, and *w* happens to be 92% of this total weight. So

*w* = 0.92 × (8 + *w*)

Solve for *w* :

*w* = 7.36 + 0.92*w*

0.08*w* = 7.36

*w* = 92

Then the total weight of the grapes before they dried out is **100 lbs**.

The length of a rectangle is 15 cm and the width is 8 cm which is the perimeter of the rectangle

Answer:

46

Step-by-step explanation:

Perimeter = 2(15 + 8)

Perimeter = 46

46

Step-by-step explanation:

Perimeter = 2(15 + 8)

Perimeter = 46

**Answer:**

46 cm

**Step-by-step explanation:**

To calculate the perimeter of a rectangle, you have to add the length with itself then add the width with itself. After that, you add both of the sums together to get the answer. For this particular question, this is what you have to do.

1.Add the length with itself 15+15=30

2.Add the width with itself 8+8=16

3. Add both sums 30+16=46

In conclusion, the perimeter of the rectangle is 46 centimeters.

Please help explanation if possible

**Answer:**

**Step-by-step explanation:**

Perimeter = 2W + 2L

160 =** ****2**W + **2**L

width = 16 feet less than length

W = L - **16 ** ------------(I)

Finding the dimensions of the court:

2W + 2L = 160

2*(L-16) + 2L = 160 {**from (I) **}

2*L - 2*16 + 2L = 160 {**Distributive property**}

2L - 32 + 2L = 160

2L + 2L - 32 = 160 {**Combine like terms**}

4L - 32 = 160 {**Add 32 to both sides**}

4L = 160 +32

4L = 192 {**Divide both sides by 4**}

L = 192/4

**L = 48**

W = 48 - 16

**W = 32**

360.8

Explanation:

3.28*110

In 110 **meter **dash, there are 360.8 **feet**.

**Simplifying **procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces **diversity **and **variation **that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and **subtraction **are all referred to as **PEMDAS**. The order of the letters in **PEMDAS **informs you what to calculate first, second, third, and so on, until the **computation **is finished, given two or more operations in a single **statement**.

Given that, there are 3.28 **feet **in a **meter**

Since,

in 1 meter there are = 3.28 feet

Thus in 110 meters there are = 3.28 * 110 feet

In 110 meters, there are = 360.8 feet

Therefore, there are 360.8 **feet **in 110 **meters **dash.

22. Juan and Mary each earn $7 an hour at a part time job.

If on a certain day Juan works 34 hours and Mary works

21 hours, what is the total amount of their earnings that day?

**Answer:**

Juan- $238

**Step-by-step explanation:**

if they earn $7 an hour then you would multiply that by how many hours they worked. So 34×7=238 for Juan and 21×7=147 for Mary.

find the HCF

eg. first expression = 4a -8

=4(a-2)

**Answer:**

**Step-by-step explanation:**

ab² + 2a²b + a³ = a(b² + 2ab + a²)

Here variable 'a' is common in all the terms. HCF = a

2) 2ab² = 2 * a * b *b

4a²b = 2 * 2 *a * a * b

6a³ = 2 * 3 * a * a * a

HCF = 2a

2ab² - 4a²b - 6a³ = 2a(b² - 2ab - 3a²)

if (a+3,b-2=b-1,2a-3 then find the value of A and B

x - p = 10

Plugin p = (2/3)x in this equation,

[tex]x -\dfrac{2}{3}x=10\\\\\dfrac{3}{3}x-\dfrac{2}{3}x=10\\\\\dfrac{1}{3}x=10\\[/tex]

x = 30

[tex]p=\dfrac{2}{3}*30\\\\p= 2 * 10[/tex]

p = 20

**Answer:**

30 and 20

**Step-by-step explanation:**

We have an integer p and another [tex]\frac{2}{3}[/tex] p , their difference is 10 , so

p - [tex]\frac{2}{3}[/tex] p = 10 ( multiply through by 3 to clear the fraction )

3p - 2p = 30 , that is

p = 30

and [tex]\frac{2}{3}[/tex] × 30 = 2 × 10 = 20

The 2 integers are 30 and 20

[tex]\frac{4}{\pi}\left[x*\sin^{-1}(x)+\sqrt{1-x^2}\right]-x+C\\\\[/tex]

====================================================

Proof:

Apply the derivative to choice A. The goal is to prove the derivative is equivalent to the given integrand.

[tex]y = \frac{4}{\pi}\left[x*\sin^{-1}(x)+\sqrt{1-x^2}\right]-x+C\\\\\frac{dy}{dx} = \frac{4}{\pi}\left[\sin^{-1}(x)+\frac{x}{\sqrt{1-x^2}}-\frac{x}{\sqrt{1-x^2}}\right]-1\\\\\frac{dy}{dx} = \frac{4}{\pi}\sin^{-1}(x)-1\\\\[/tex]

It's far from obvious, but we can apply a bit of algebra like so

[tex]\frac{dy}{dx} = \frac{4}{\pi}\sin^{-1}(x)-1\\\\\frac{dy}{dx} = \frac{4}{\pi}\sin^{-1}(x)-\frac{\pi}{\pi}\\\\\frac{dy}{dx} = \frac{4\sin^{-1}(x)-\pi}{\pi}\\\\[/tex]

Next, we divide every term by 2. This is so we can replace the pi terms with pi/2

[tex]\frac{dy}{dx} = \frac{4\sin^{-1}(x)-\pi}{\pi}\\\\\frac{dy}{dx} = \frac{2\sin^{-1}(x)-\frac{\pi}{2}}{\frac{\pi}{2}}\\\\[/tex]

We do this to take advantage of the trig identity [tex]\sin^{-1}(x)+\cos^{-1}(x) = \frac{\pi}{2}[/tex]

So we'll be replacing every instance of "pi/2" with the left hand side of that equation just mentioned.

Therefore,

[tex]\frac{dy}{dx} = \frac{2\sin^{-1}(x)-\frac{\pi}{2}}{\frac{\pi}{2}}\\\\\frac{dy}{dx} = \frac{2\sin^{-1}(x)-\left(\sin^{-1}(x)+\cos^{-1}(x)\right)}{\sin^{-1}(x)+\cos^{-1}(x)}\\\\\frac{dy}{dx} = \frac{2\sin^{-1}(x)-\sin^{-1}(x)-\cos^{-1}(x)}{\sin^{-1}(x)+\cos^{-1}(x)}\\\\\frac{dy}{dx} = \frac{\sin^{-1}(x)-\cos^{-1}(x)}{\sin^{-1}(x)+\cos^{-1}(x)}\\\\[/tex]

This shows that differentiating the expression in choice A leads to the given integrand.

If we reverse all of the steps mentioned, then we can show that:

[tex]\displaystyle\frac{dy}{dx} = \frac{\sin^{-1}(x)-\cos^{-1}(x)}{\sin^{-1}(x)+\cos^{-1}(x)}\\\\\\ \int\frac{dy}{dx}dx = \int\frac{\sin^{-1}(x)-\cos^{-1}(x)}{\sin^{-1}(x)+\cos^{-1}(x)}dx\\\\\\y = \frac{4}{\pi}\left[x*\sin^{-1}(x)+\sqrt{1-x^2}\right]-x+C\\\\[/tex]

since integrals and derivatives are tied together through inverse processes (one undoes the other more or less).

A city has a population of 240000 people. Suppose that each year the population grows by 5%. What will the population be after 8 years?

240000 * 1.05^8 = 354589

**Answer:**

**354,589** people.

**Step-by-step explanation:**

Each year the population is 105% times the previous year.

105% = 1.05.

so in 8 years population will be:

240000*(1.05)^8

= 354,589.

If p is true and q is false, the p->q is ____

true.

never

always

sometimes

**Answer:**

never

**Step-by-step explanation:**

p->q means if p is true, then q must also be true

but since q is false, p->q is never true

**Answer: Never**

Explanation:

The notation p -> q refers to a conditional statement.

Conditionals are only false when the first part (p) is true while the second part (q) is false. In other words, the template true --> false ultimately leads to a false statement. Otherwise, the entire thing is true.

In our case, we have something that fits the "true -> false" template, so that's why p -> q is never true when p = true and q = false.
