Write a proportion that can be used to find the cost of 10 notebooks if 3 notebooks cost $1.98.

Answers

The solution to the problem is as follows:

For 3 notebooks you pay $1.98 so the ratio is 1:0.66.
For 10 notebooks, then we could scale the ratio and it will become 10:6.60. So they will cost you $6.60.

Three water pipes are used to fill a swimming pool. The 1st pipe alone takes 8 hours to fill the pool, the 2nd pipe alone takes 12 hours to fill the pool, and the 3rd pipe takes 24 hours to fill the pool. If all 3 pipes are opened at the same time, how long will it take all 3 together to fill the pool?

Answers

For 4 h. The first pipe fills the whole pool for 8 hours so from here we see that it fills 1/8 each hour. The second pipe fills it for 12 hours so it fills 1/12 each hour. The third pipe fills it for 24 hours so it fills 1/24 each hour. Now the three of them together fill 1/8 + 1/12 + 1/24 of the pool each hour. That equals: 1st pipe 3/24 of the pool each hour, the 2nd pipe 2/24 of the pool each hour and the 3rd 1/24 each hour. So, the three pipes together fill 3/24 + 2/24 + 1/24 each hour. That's 6/24 of the pool each hour.
1st hour: 6/24
2nd hour: 12/24
3rd hour: 18/24
4th hour: 24/24

The folding chair has different settings that change the angles formed by its parts. Suppose m2 is 34 and m3 is 76. Find m1The diagram is not to scale.
A. 130
B. 110
C. 100
D. 120

Answers

the answer is

first, the sum of angles in triangle is always 180°
so mx + m2 +m3 = 180°, so mx=1800-76-34=70°
but according to the figure m1 + mx=180°, so m1=180-mx=180-70=110°

the m1 = 110°

In ELECTRONICS, the total resistance to the flow of electricity in a circuit is called the impedance, Z. Impedance is represented by a complex number. The total impedance in a series circuit is the sum of individual imepedances. The impedance in one part of a circuit is Z1 = 3 + 4i. In another part of a circuit, the impedance is Z1 = 5 - 2i. What is the total impedance of the circuit?

Answers

Total impedance of circuit is Z1 + Z2

Here it is important that real numbers we sum with real numbers and complex numbers with complex numbers

Let Zs represent total impedance.

Zs = Z1 + Z2 = 3 + 4i + 5 - 2i = 3 + 5 + 4i - 2i = 8 + 2i

Answer is :

8+2i

Final answer:

The total impedance of the circuit is 8 + 2i.

Explanation:

The total impedance in a series circuit is the sum of the individual impedances. To find the total impedance of the circuit, add the real parts and imaginary parts separately. In this case, Z1 = 3 + 4i and Z2 = 5 - 2i. So, the total impedance Zt = (3 + 5) + (4 - 2)i. Simplifying this, Zt = 8 + 2i.

A box has a width 9 inches less than its height and a length 7 inches more than its height.
a. If h is the height of the box, write a polynomial that represents the volume of the box.
b. Use this polynomial to calculate the volume for h = 17 inches.

Answers

So everything in this problem is in terms of height (h). We'll abbreviate width to w and length to l and volume to v

l=h+7
w=h-9

a.
volume is height x width x length

v=h*(h+7)*(h-9)

now we have to multiply these values

h*(h+7)=h^2+7h

(h^2+7h)*(h-9)=h^3-9h^2+7h^2-63h=h^3-2h^2-63h

b.
now we plug in h=17
v=17^3 -2(17)^2 -63(17) = which comes out to 2686

for the parallelogram, if m<2+5x-28 abd m<4=3x-10, find m< 3. ...?

Answers

Final answer:

After finding the value of x by equating m<2 and m<4, we calculate m<4 and then use the property of supplementary angles in a parallelogram to find that m<3 is 163 degrees.

Explanation:

To solve for m<3 in the parallelogram with m<2 = 5x - 28 and m<4 = 3x - 10, we first find the value of x. Given that opposite angles in a parallelogram are equal (m<2 = m<4), we set the two equations equal to each other and solve for x:

5x - 28 = 3x - 10

5x - 3x = 18

2x = 18

x = 9

Now that we have the value of x, we can substitute it into the equation for either angle to find the measure of that angle. Since m<4 = 3x - 10:

m<4 = 3(9) - 10 = 27 - 10 = 17

In a parallelogram, adjacent angles are supplementary, meaning they add up to 180 degrees. Therefore, to find m<3, we subtract m<4 from 180 degrees:

m<3 = 180 - m<4

m<3 = 180 - 17 = 163

Thus, m<3 in the parallelogram is 163 degrees.

Final Answer:

The measure of angle 3 in the parallelogram is [tex]$ m\angle 3 = 2x - 18 $.[/tex]

Explanation:

In a parallelogram, opposite angles are equal. Therefore, we can set up an equation based on the given angle measures:

[tex]\[ m\angle 2 + m\angle 3 = 180^\circ \][/tex]

Substitute the given expressions for[tex]$ m\angle 2 $ and $ m\angle 4 $:[/tex]

[tex]\[ (2 + 5x - 28) + (3x - 10) = 180 \][/tex]

Combine like terms:

[tex]\[ 5x + 3x - 28 - 10 + 2 = 180 \][/tex]

[tex]\[ 8x - 36 = 180 \][/tex]

Add 36 to both sides:

[tex]\[ 8x = 216 \][/tex]

Divide by 8:

[tex]\[ x = 27 \][/tex]

Now that we have the value for x, substitute it into the expression for $ [tex]m\angle 3 $:[/tex]

[tex]\[ m\angle 3 = 2(27) - 18 \][/tex]

[tex]\[ m\angle 3 = 54 - 18 \][/tex]

[tex]\[ m\angle 3 = 36 \][/tex]

Therefore, the measure of angle 3 in the parallelogram is [tex]$ m\angle 3 = 36^\circ $.[/tex]

A. geometric

C. arithmetic

Answers

b: neither arithmetic nor geometric

The given sequence describes the type of sequence that is neither arithmetic nor geometric. which is the correct answer would be an option (B).

What is an arithmetic sequence?

An arithmetic sequence is defined as an arrangement of numbers that is a particular order.

The sequence is given in the question following as:

1, 6, 7, 13, ...

We have to identify the type of given sequence

As per the given question, we have

1, 6, 7, 13, ...

For checking as an arithmetic sequence :

Common difference between 1 and 6 is d = 6 - 1 = 5

Common difference between 6 and 7 is d = 7 - 6 = 1

Since the common difference between consecutive terms is not the same, this means it's not an arithmetic sequence.

For checking as a geometric sequence :

Common ratio between 1 and 6 is r = 6/1 = 6

Common ratio between 6 and 7 is r = 7/6

Since the common ratio between consecutive terms is not the same, this means it's not a geometric sequence

Thus, the given sequence describes the type of sequence that is neither arithmetic nor geometric.

3^x : write in terms of base e and simplify! ...?

Answers

3^x : write in terms of base e would

The given function is exponential. Meanwhile [tex]<b>change of base</b>[/tex] has something to do with logarithms. So we convert the function to logarithm function, change to the required base and convert back to exponential function.

Let

[tex]y = {3}^{x} [/tex]

Writing the above exponential equation as a logarithmic equation, we obtain;

[tex] log_{3}(y) = x[/tex]

We can apply the change of base formula to obtain,

[tex] \frac{ log_{e}(y) }{ log_{e}(3) } = x[/tex]

Or

[tex] \frac{ ln(y) }{ln(3) } = x[/tex]

We can cross multiply to obtain;

[tex] ln(y) = x ln(3) [/tex]

Taking logarithm of both sides to base e, we obtain;

[tex] {e}^{ ln(y) } = {e}^{x ln(3) } [/tex]

This implies that,

[tex]y= {e}^{x ln(3) } [/tex]
But we know that,
[tex]y = {3}^{x} [/tex]
Hence
[tex] {3}^{x} = {e}^{x ln(3)} [/tex]

If 6 is 24% of a number, what is 40% of the same number?

(A) 8
(B) 10
(C) 15
(D) 20

Answers

the answer is 10.the unknown number is 25.

To find 40% of the number where 6 is 24%, we first determine the whole number by dividing 6 by 0.24 to get 25. Then we calculate 40% of 25, which is 10.

If we know that 6 is 24% of a number, we can find the whole number by dividing 6 by 0.24. Once we have the full number, we can calculate 40% of it. Let's do the calculation step by step.

Calculate the whole number using the given percentage: Whole number = 6 / 0.24.

Perform the division to find the whole number: Whole number = 25.

Calculate 40% of the whole number: 40% of 25 = 0.40 * 25.

Perform the multiplication to find 40% of the number: 40% of 25 = 10.

Therefore, 40% of the same number is 10.

"Find the value of the derivative (if it exists) at each indicated extremum. (If an answer does not exist, enter DNE.)
f (x) = cos(πx/2)

Answers

Answer: The derivate is f'(x) = -sin(πx/2)*(π/2)

Step-by-step explanation:

We want the value of the derivate at each point marked:

As you may know, the derivate of cos(x) is equal to -sin(x)

And in our case:

f(x) = cos(πx/2)

f'(x) = -sin(πx/2)*(π/2)

Where the rule used is that the derivate of f(g(x)) is equal to f'(g(x))*g'(x)

Now, as you may see, in both the marked points the curve changes of direction, so the tangent line in that point must be zero, letsinput the values of x in the derivate and see if this is true:

f'(0) = -sin(π*0/2)*(π/2) = -sin(0)*(π/2) = 0

f'(2) = -sin(π*2/2)*(π/2) = -sin(π)*(π/2) = 0

So this makes sense.
