Answer:

Quotient given:

\frac{6-3 \sqrt[3]{6} }{ \sqrt[3]{9} }

Answer:

2 \sqrt[3]{3} - \sqrt[3]{18}

Explanation:

1) Rationalize by multiplying numerator and denominator by         \sqrt[3]{9}

2)

\frac{6-3 \sqrt[3]{6} }{ \sqrt[3]{9} } \frac{\sqrt[3]{9}}{\sqrt[3]{9}}

3) Due the operations

\frac{6 \sqrt[3]{3}-3 \sqrt[3]{6.3}}{ \sqrt[3]{27} }

\frac{6 \sqrt[3]{3}-3 \sqrt[3]{6.3}}{ 3 }=2 \sqrt[3]{3} - \sqrt[3]{18}

Time taken by the car to cover 260 km is 2.6 hrs

Step-by-step explanation:

Speed = Distance/Time = 150/1.5 = 100 km/hr

Time = Distance/Speed = 260/100 = 2.6 hrs

2 x 7 x 7 or in exponential form, 2 x 7². 98 turns into 2 times 49, then 49 turns into 7 times 7.

The prime factorization of 98 is equal to 2 x 7².

The prime factorization of 98 involves breaking it down into prime numbers that multiply together to give the original number, 98.

The process for finding the prime factors of 98 is as follows:

Start with the smallest prime number, 2.

Since 98 is an even number, it is divisible by 2. So, divide 98 by 2 to get 49.

Now, 49 is not divisible by 2, so we try the next prime number, which is 3.

Since 49 is not divisible by 3 either, we move to the next prime number, 5, and so on until we reach 7, which does divide 49.

Divide 49 by 7 to get 7. So, 49 is 7 multiplied by 7, both of which are prime numbers.

Putting it all together, the prime factorization of 98 is 2 × 7 × 7 or 2 × 7².

Answer:

that's easy just with your number line put then to least to greatest

Solution:

Given that we have to factor -3y - 18

Use the distributive property,

a(b + c) = ab + bc

From given,

-3y - 18

Factor out the greatest common factor of 3 and 18

The factors of 3 are: 1, 3

The factors of 18 are: 1, 2, 3, 6, 9, 18

Then the greatest common factor is 3

Factot out 3 from given expression

-3y - 18 = 3( - y - 6)

Or else we can rewrite as,

-3y - 18 = -3(y + 6)

Thus the given expression is factored

Answer: 1.3 meters taller. so 103 cm.

Step-by-step explanation:

Answer:

103cm

Step-by-step explanation:

From the question given, we obtained the following data:

Height of the boy = 97cm

Height of the elder brother = 2m

First let us convert the height of the elder brother to cm. This is illustrated below:

1m = 100cm

2m = 2 x 100 = 200cm

So, the elder brother is 200cm tall. To know how much taller the elder brother is than the boy, subtract the height of the boy from that of the elder bother' as shown below:

200 — 97 = 103cm

Therefore, the elder brother is 103cm taller than the boy

The total number of books based on the given percentage will be 20 including 15 paperback books.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

Suppose Mr. Sanchez bought a total of x number of books.

75% of x = (75/100)x

This is the paperback thus,

(75/100)x = 15

x = 1500/75 = 20

Thus, the number of total books = 20 including 15 paperback books.

Hence "The total number of books based on the given percentage will be 20 including 15 paperback books".

Answer:80 pie

Step-by-step explanation:

90 in terms of pi is [tex]\frac{\pi}{2}[/tex] .

Step-by-step explanation:

We know that ,

We have to convert 90 in terms of pi i.e. degree to radians:

⇒ [tex](90)\frac{\pi }{180}[/tex]

⇒ [tex]\frac{90 }{180}(\pi)[/tex]

⇒ [tex]\frac{1 }{2}(\pi)[/tex]

⇒ [tex]\frac{\pi}{2}[/tex]

Therefore, 90 in terms of pi is [tex]\frac{\pi}{2}[/tex] .

The height of an object off the ground h after t seconds is [tex]h(t)=-16t^2+128t[/tex] and the rate of change of h is 192.

Given data:

The average rate of change of a function over an interval [a,b] is given by the formula:

[tex]R=\frac{f(b)-f(a)}{b-a}[/tex]

Now, the function [tex]h(t)=-16t^2+128t[/tex] represents the height of an object off the ground at time t seconds. We are asked to find the average rate of change of h over the interval [4,8].

So, the value of a = 4 and b = 8.

[tex]h(8)=-16(8)^2+128(8)[/tex]

[tex]h(4)=-16(4)^2+128(4)[/tex]

On simplifying the equation:

[tex]R=\frac{h(8)-h(4)}{8-4}[/tex]

[tex]R=\frac{768}{4}[/tex]

[tex]R=192[/tex]

Hence, the average rate of change of h over the interval is 192 feet per second.

#SPJ12

The average rate of change of h over the interval [4,8] is -64 feet per second. This is found by substituting the values of a = 4 and b = 8 into the equation h(t) = -16t² + 128t and into the formula for average rate of change.

To find the average rate of change of h over the interval [4, 8], we use the formula for the average rate of change: (h(b) - h(a)) / (b - a). Here, a = 4 and b = 8.

First, calculate h(a) and h(b) using the given equation h(t) = -16t² + 128t:

Substitute h(a) and h(b) into the formula to get:
(0 - 256) / (8 - 4) =-256/4 = -64.

So, the average rate of change of h over the interval [4, 8] is -64 feet per second.

Answer:

[tex] {f}^{ - 1} (x) = 3 {x}^{2} - 3[/tex]

Step-by-step explanation:

We want to find the inverse of

[tex] y = \sqrt[3]{ \frac{x}{3} + 1} [/tex]

We interchange x and y to get:

[tex]x= \sqrt[3]{ \frac{y}{3} + 1} [/tex]

We solve for y;

[tex] {x}^{2} = \frac{y}{3} + 1[/tex]

Multiply through by 3

[tex]3 {x}^{2} = y + 3[/tex]

Subtract 1 from both sides:

[tex]y = 3 {x}^{2} - 3[/tex]

Therefore the inverse is

[tex] {f}^{ - 1} (x) = 3 {x}^{2} - 3[/tex]

Step-by-step explanation:

Width of the rectangle is 4 units

Step-by-step explanation:

Area of the rectangle = length × width

⇒ 20 = x (x + 1)

⇒ 20 = x² + x

⇒ x² + x - 20 = 0

⇒ x² + 5x - 4x - 20 = 0 (Using Product Sum rule to factorize)

⇒ x(x + 5) - 4(x + 5) = 0

⇒ (x + 5)(x - 4) = 0

⇒ x = -5, 4 (negative value is neglected)

x = 4

Final answer:

The solution reveals that the width of the rectangle is 4 units.

Explanation:

The student is asking to find the width of the rectangle when the length is given as the sum of the width and 1 unit, and the area of the rectangle is 20 square units.

To solve this, we can set up an equation using the area formula for a rectangle, A = length * width, where the area (A) is 20 square units.

Let's denote the width as w units.

Then the length can be expressed as w + 1 units. Substituting these expressions into the area formula gives us:

20 = w * (w + 1)

Expanding the right side, we get:

20 = w² + w

This is a quadratic equation, which we can solve by setting it equal to zero:

w² + w - 20 = 0

Factoring the quadratic equation, we find:

(w + 5)(w - 4) = 0

Therefore, w could be -5 or +4. Since a width cannot be negative, the only reasonable solution is w = 4 units.

Thus, the width of the rectangle is 4 units.

Step-by-step explanation:

The radius of the circle is approximately 7.5 cm, and the corresponding area is approximately 56.25π cm², as calculated using the formulas for circumference and area. Here option C is correct.

1: Find the radius using the circumference formula

We know the circumference C = 157 cm.

We also know the formula for circumference of a circle: C = 2πr, where r is the radius.

Rearranging the formula to solve for r, we get: r = C / (2π).

Substituting C with 157, we get: r = 157 / (2π) ≈ 7.5 cm.

2: Calculate the area using the area formula

Now that we know the radius, we can use the formula for the area of a circle: A = πr², where A is the area.

Substituting r with 7.5, we get: A = π * (7.5)² ≈ 56.25π cm².

Therefore, the area of the circle is 56.25π cm². Here option C is correct.
