HOBBIES Tawa wants to increase her rock collection by a power of three this year and
then increase it again by a power of two next year. If she has 2 rocks now, how many
rocks will she have after the second year?

To obtain y - x from x - y, add 2y - 2x to x - y which simplifies to y - x.

To transform x - y into y - x, we need to add something that effectively swaps x and y while also changing the sign of both variables. This is a classic example of using the property that A - B is the same as A + (-B). Applying this to our expression, if we add 2y to x - y, we'll get x + y. But, we need y - x, not x + y. So, we need to subtract x twice. Once to cancel out the original x, and a second time to create the negative x in the desired expression. Essentially, we add -2x to our new expression, x + y. So, the final answer is (x - y) + 2y - 2x, which simplifies to y - x.

Answer:

[tex]k = - \frac{3}{2}[/tex]

Step-by-step explanation:

If y varies directly with x, then from the relation of direct variation we can write y ∝ x

Now, converting the variation relation to equation relation,

⇒ y = kx  ........... (1) {Where k is the constant of variation}

Now, given that at y = - 3, x = 2 and this solution will satisfy the equation (1).

Hence, - 3 = 2k

⇒ [tex]k = - \frac{3}{2}[/tex] (Answer)

Final answer:

To show that 2/3 divided by 3/4 equals 8/9, we multiply 2/3 by the reciprocal of 3/4, which is 4/3, yielding the answer 8/9. This illustrates that division by a fraction involves multiplying by its reciprocal.

Explanation:

To explain how the model shows that 2/3 ÷ 3/4 = 8/9, we need to understand division of fractions and the concept of reciprocals. Division of fractions is the same as multiplying by the reciprocal of the divisor. The reciprocal of 3/4 is 4/3. Therefore, to divide 2/3 by 3/4, we multiply 2/3 by 4/3:

(2/3) × (4/3) = 8/9

This demonstrates that dividing by a fraction is equivalent to multiplying by its reciprocal. We can also use familiar scenarios to rationalize the answer. For instance, we know that half of one half (1/2 × 1/2) equals one quarter (1/4) and this helps us understand the process - we are scaling a number by another when we multiply fractions.

When discussing multiplication and division of fractions, it is useful to remember that these operations are fundamentally linked; division is essentially multiplication by a reciprocal. Hence, dividing 2/3 by 3/4 is the same as multiplying 2/3 by the reciprocal of 3/4, which is 4/3, resulting in 8/9.

Answer:

Andre is taller.

Step-by-step explanation:

I assume Andre's height is 1.7 m.

Let's convert Andre's height to cm.

1 m = 100 cm

1.7 m = 1.7 * 1 m = 1.7 * 100 cm = 170 cm

Andre is 170 cm tall. Diego is 165 cm tall.

Since 170 cm > 165 cm, Andre is taller.

1.7 m = 170 cm

170 cm > 165 cm

Andre > Diego

Answer:

A) y=-3/2x+5/2

Step-by-step explanation:

y=mx+b

6x+4y=10

4y=10-6x

4y=-6x+10

y=-6/4x+10/4

simplify

y=-3/2x+5/2

The equation 6x + 4y = 10 written in slope-intercept form is y = -3/2x + 5/2.

The equation Y = mx + b exists in the slope-intercept form of the equation of a straight line. In the equation y = mx + b, m exists the slope of the line and b exists the intercept. X and y describe the distance of the line from the x-axis and y-axis, respectively. The value of b exists equivalent to y when x = 0, and m indicates how steep the line exists.

Let the equation be, 6x + 4y = 10

Simplifying the above equation we get

4y = 10 - 6x

4y = -6x + 10

y=-6/4x + 10/4

simplify

y = -3/2x + 5/2.

Therefore, the correct answer is option A. y= -3/2x + 5/2.

r^9- r^3

answer:

r^6

Which expression is equivalent to [tex]r^9/r^3[/tex] ?  The correct answer is b) [tex]r^6[/tex].

To simplify the expression [tex]r^9/r^3[/tex], we need to apply the rule of exponents. When dividing two terms with the same base, you can subtract the exponents.

In this case, both [tex]r^9[/tex] and [tex]r^3[/tex] have the same base 'r', so we subtract the exponent of [tex]r^3[/tex] from the exponent of [tex]r^9[/tex].

[tex]r^9/r^3[/tex] = [tex]r^{9-3}[/tex] = [tex]r^6[/tex].

In this problem, we are given the expression [tex]r^9/r^3[/tex] and we need to find an equivalent expression for it. To do that, let's understand the rules of exponents.

In general, when you have a term raised to a certain power and you divide it by the same term raised to a different power, you can simplify it by subtracting the exponents. For example, [tex]a^m / a^n = a^{m-n}[/tex].

Now, looking at our expression, [tex]r^9/r^3[/tex], we notice that both terms have the same base 'r'. According to the rule mentioned above, we can simplify the expression by subtracting the exponent of r3 from the exponent of [tex]r^9[/tex].

[tex]r^9/r^3[/tex] = [tex]r^{9-3}[/tex] = [tex]r^6[/tex].

So, the expression [tex]r^9/r^3[/tex] is equivalent to [tex]r^6[/tex]. This means that when you have a term raised to the power of 9 and you divide it by the same term raised to the power of 3, the result is the term raised to the power of 6.

In conclusion, the correct answer is b) [tex]r^6[/tex], as it represents the equivalent expression to [tex]r^9/r^3[/tex] after applying the rules of exponents.

Answer:

The value of g'(10)=[tex]\frac{(-1)}{16}[/tex]

Step-by-step explanation:

Given function is f(x)=[tex]\frac{4}{x} + 2[/tex]

Take f(x)=y

y=[tex]\frac{4}{x} + 2[/tex]

Subtract 2 from both side.

y-2=[tex]\frac{4}{x}[/tex]

x=[tex]\frac{4}{y-2}[/tex]

The inverse of f(x) is written as [tex] \frac{4}{y-2}[/tex]

It is said as g is inverse of f

g(y)=\frac{4}{y-2}[/tex]

g(y)=[tex]\frac{4}{y-2}[/tex]

g(10)=[tex]\frac{4}{10-2}[/tex]

g(10)=[tex]\frac{1}{2}[/tex]

Differentiating both sides we get,

g'(y)=[tex]\frac{4(-1)}{(y-2)^{2}}+0[/tex]

g'(y)=[tex]\frac{(-4)}{(y-2)^{2}}[/tex]

Final answer:

To find out how much was spent on fresh flowers, 10% of the monthly budget of $5,000 was calculated, resulting in $500 spent on fresh flowers.

Explanation:

If the monthly budget for the front of the house is $5,000, and you spent 10% of the budget on fresh flowers, you can calculate the amount spent on fresh flowers by finding 10% of $5,000. To do this, you simply multiply the total budget by the percentage (expressed as a decimal).

To express 10% as a decimal, you divide 10 by 100, which gives 0.10. Next, multiply the monthly budget by this decimal:

0.10 × $5,000 = $500

Therefore, you spent $500 on fresh flowers.

Given that  

Annual membership fee of store where Mrs. William shops = $30

Cost of one fruit basket which Mrs. William as gifts for her co-workers = $15

Total amount spent by Mrs. William = $150

Given that "b" represents number of basket purchased

Equation which models the above scenario is as follows

15b+ 30=105   ------ (1)

Where b represents number of fruit basket purchased by Mrs. William

Need to calculate number of fruit basket purchased by Mrs. William

For which we need to solve equation (1) for b  

On solving we get

15b+ 30 = 105    

On Subtracting 30 from both sides we get

15b + 30 – 30 = 105 – 30

=> 15b = 75

On dividing both sides by 15 we get  

[tex]\begin{array}{l}{\frac{15 b}{15}=\frac{75}{15}} \\\\ {=>b=5}\end{array}[/tex]

- Multiply all terms of the equation by 4 to cancel the denominator

 of the 2nd term in the left hand side

∵ The equation is [tex]4(2x) +4 (\frac{1-x}{4})=4(3)[/tex]

∴ 8x + (1 - x) = 12

∴ 8x + 1 - x = 12

- Add like terms

∴ (8x - x) + 1 = 12

∴ 7x + 1 = 12

- Subtract 1 from both sides

∴ 7x = 11

- Divide both sides by 7

∴ [tex]x=\frac{11}{7}[/tex]

Answer:

Neil had a better free throw rate.

Step-by-step explanation:

This is because Neil Shot less, but made more.

I hope this helps you!

Final answer:

Neil had a better free throw percentage at approximately 62.87% compared to Avid's 60.07% by calculating the number of successful throws divided by the total attempts and multiplying by 100.

Explanation:

The question involves comparing the free throw rates of two basketball players to determine who had a better free throw percentage. To find the free throw percentage, we divide the number of successful free throws by the total number of attempts and then multiply by 100.

For Neil:

(215 free throws ÷ 342 attempts) × 100 = ~62.87%

For Avid:

(358 free throws ÷ 596 attempts) × 100 = ~60.07%

Neil had a better free throw percentage than Avid as 62.87% is higher than 60.07%.
