The individual that has a greater rate of reading is Rhoni.

Rate measures how fast a person is reading a book. Rate is the total pages read per time. Rate is determined by dividing total pages read by the total time spent reading.

Division is the operation used in mathematics that is used to determine the quotient of two or more numbers. It entails grouping a number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations.

Rie's rate = pages read / time

195 / 3 = 65 pages per hour

325 / 5 = 65 pages per hour

Rie's rate is 65 pages per hour. While Rhoni's rate is 75 pages per hour. This means that Rhoni reads faster than Rie.

Jon's bathtub exists rectangular and its base exists 18 ft². The water level rising if Jon is filling the tub at a rate of 0.2 ft³/min is 0.011 ft/min.

A differential equation in mathematics exists an equation that links the derivatives of one or more unknown functions. Applications often involve functions that reflect physical quantities, derivatives that depict the rates at which those values change, and a differential equation that establishes a connection between the three.

If we take a look at a rectangular bathtub, the volume of the bathtub can be expressed as:

Volume (V) = length × breadth × height

where; base = length × breadth = 18ft²

The volume of the rectangular bathtub = 18h ......... (1)

Using differentiation to differentiate 18h with respect to t implicitly, then:

[tex]$\frac{\mathrm{dV}}{\mathrm{dt}}=18 \frac{\mathrm{dh}}{\mathrm{dt}}$$[/tex]

When the rate of rising of the volume is 0.2 ft² / min

[tex]$0.2=18 \frac{\mathrm{dh}}{\mathrm{dt}}$$[/tex]

substitute the values in the above equation, we get

[tex]$\frac{\mathrm{dh}}{\mathrm{dt}}=\frac{1}{18} \times(0.2)$$[/tex]

[tex]$\frac{\mathrm{dh}}{\mathrm{dt}}=0.011 \mathrm{ft} / \mathrm{min}$$[/tex]

Therefore, we can conclude that the rate at which the water level rises if Jon is filling the tub at 0.2 ft³/min exists 0.011 ft/ min.

The improper fraction equivalent of the fraction 2 1/4 is 9/4.

Improper fraction:

Basically, the improper fraction is also the fraction where the numerator is greater than or equal to the denominator.

Given,

Here we have the mixed fraction 2 1/4.

And we have to convert this mixed fraction into improper fraction.

The conversion from mixed fraction to an improper fraction will follow the following formula,

numerator = (denominator × whole number) +  numerator of mixed fraction

Based on the this rule, the numerator of the improper fraction is,

=> numerator = (4 x 2) + 1

=> numerator = 8 + 1

=> numerator = 9

The denominator will remain same.

Therefore, the resulting improper fraction is 9/4.

Given,

sin(40 + 2°) cosec(30 + 5°) = 1

To prove the trigonometry function equal to 1.

Now, According to the question:

We know that

Sin 42° = 0.66913061

Cosec 35° = 1.7434468

sin(40 + 2°) cosec(30 + 5°) = 1

sin 42° × cosec 35° = 1

Plug the values of sin and cosec in above function:

0.66913061 × 1.7434468

= 1.16659

But we take the before decimal value i.e., 1

Hence,  sin(40 + 2°) cosec(30 + 5°) = 1 we proved that by the values.

79 degrees plus X would make 180 degrees, because these two angles make up a straight angle.

So, 79 + X = 180

    -79          -79

         X=101 degrees.

Y is 79 degrees because it is an alternate interior angle to the other 79 degree angle.

Z is 101 degrees because X and Z are corresponding angles, which means they are equal.

If Z is 101 degrees, Y must be 79 degrees because Y and X make up a straight angle.

Answer:

X is 101 degrees. Y is 79 degrees. Z is 101 degrees.

Yes, you are right!

First of all, we will subtract [tex]5[/tex] from each side.

Then we multiply both sides by [tex]4[/tex].

Then add [tex]3[/tex] to each side.

Finally, we divide each side by [tex]2[/tex].

[tex]\boldsymbol{\sf{\cfrac{2x-3}{4}+5=10 }}[/tex]

Multiply the two sides of the equation by 4.

2x - 3+20 = 40

Add −3 and 20 to get 17.

2x+17 = 40

It remains 17 on both sides.

2x = 40−17

Subtract 17 of 40 to get 23.

2x = 23

Divide both sides by 2.

The length of the first piece is 3 inches, and the second and third pieces are each 9 inches

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

Given that a 21-foot beam is to be cut into three pieces so that the second and third pieces are each 3 times the length of the first piece.

We have to determine the length of each piece.

Let x represents the length of the first piece

As per the given condition,

x + 3x + 3x = 21

7x = 21

x = 21 / 7

x = 3

Thus, the first piece is 3 inch

So 2nd piece is 3×3 = 9 inches ( 3 times to first piece )

And 3rd  piece is  3×3 = 9 inches (  3 times to first piece )

Therefore, the length of the first piece is 3 inches, and the second and third pieces are each 9 inches

Answer:

(x - 3) (5x + 1)(x + 1).

Step-by-step explanation:

5x^3 - 9x^2 - 17x - 3

As the first coefficient is 5 and the last -3, so product is -15, we could try if (x-3) is a factor:

By the Factor Theorem, if x-3 is a factor then f(3) = 0.

f(3) = 5(3)^3 - 9(3)^2 - 17(3) - 3

= 135 - 81 - 51 - 3 = 0

So, x - 3 is a factor.

Now divide:

x - 3)5x^3 - 9x^2 - 17x - 3(5x^2 + 6x + 1 <------- Quotient

       5x^3 - 15x^2

                    6x^2 - 17x

                    6x^2 - 18x

                                    x - 3

                                    x - 3

                                     .......

Factoring 5x^2 + 6x + 1:

= (5x + 1)(x + 1)

So, the answer is:

(x - 3) (5x + 1)(x + 1).

The factors of the quadratic equation are found as the 7 and -3/2

For the given question, the quadratic equation is give as;

2x² - 11x - 21 = 0

Find the factors of -21×2 = 42 such that on subtraction it gives -11.

2x² - 14x + 3x - 21 = 0

Take 2x common from the first two terms and 3 from the last two terms.

2x(x - 7) + 3(x - 7) = 0

Take (x - 7) common from the terms.

(x - 7)(2x + 3) = 0

Then,

x - 7 = 0

x = 7

and, 2x + 3 = 0

x = -3/2

Calculating the sine, cosine and tangent of the angle pi/6 (that is, 30°), we have that:

Answer:

Trapezoid

Step-by-step explanation:

The area of this parallelogram is its height (half-height of the trapezoid) times its base (sum of the bases of the trapezoid)

The height of plant will be 7.56cm tall after 2 weeks

The original height of the plant is 6.2cm

The height increases by 11% each week

= 11/100

= 0.11

The increase of the plant in a week

= 0.11 × 6.2

= 0.682

The height of the plant after two weeks can be calculated as follows

= 0.682 + 0.682

= 1.364

= 6.2 + 1.364

= 7.56

Hence the height of the plant after 2 weeks is 7.56cm

B) The total cost to stay for 6 nights is; $165

C) No, 3 night does not cost half as much as the cost for 6 nights due to the addition mandatory cost of $15.

We are told that a pet hotel charges $25 per night to keep a dog. We are also told that there is a mandatory $15 examination fee when the dog arrives there.

A) If the number of nights spent is n, then the function rule here for the total cost  is;

T = 25n + 15

B) We are told that the number of nights is 6 nights. Thus, we will just plug in 6 for n into the total cost equation to get;

T(6) = 25(6) + 15

T(6) = $165

C) The cost of 3 nights would be;

T(3) = 25(3) + 15

T(3) = $90
