Step-by-step explanation:

I am not allowed to answer more than 3 questions. So I will do the first 3.

15a. i) (2/3) = 4/9

ii) (2/3) = 8/27

iii) (2/3) = 16/81

b. The product is small because you are finding the fraction of a fraction.

16. Compared to the factors, the product is less than each fraction. This is because, as stated above, you are trying to find a fraction (a part of the whole) of another fraction. When you multiply a whole number by a fraction, the whole number decreases. The same applies to a fraction.

17a. 0.4 × 0.3 = 0.12

b. 0.4 = 4/10 = 2/5

0.3 = 3/10

3/10 × 2/5 = 6/50

Which equation justifies why 93-3√9?

Simora [160]

Considering the conversion from exponent to radical, the equation that justifies why the expression $9^{\frac{1}{3}} = \sqrt[3]{9}$ is correct is.

$(9^{\frac{1}{3}})^{3} = 9^{\frac{3}{3}} = 9$

<h3>How is the conversion from exponent to radical realized?</h3>

The conversion of rational exponents to radical notation is modeled by:

$a^{\frac{n}{m}} = \sqrt[m]{a^n}$

In this problem, the expression is:

$9^{\frac{1}{3}} = \sqrt[3]{9}$

And the equation that shows that this is correct is:

$(9^{\frac{1}{3}})^{3} = 9^{\frac{3}{3}} = 9$

Please answer the attached question by selecting of the the given answers.

hichkok12 [17]

Answer:

Step-by-step explanation:

Given that Q varies inversely as the square of p then the equation relating them is

Q = $\frac{k}{p^2}$ ← k is the constant of variation

To find k use the condition Q = 36 when p = 7

k = Qp² = 36 × 7² = 36 × 49 = 1764

Q = $\frac{1764}{p^2}$ ← equation of variation

When p = 6, then

Q = $\frac{1764}{6^2}$ = $\frac{1764}{36}$ = 49 → C

Find the circumference of 20yd

Svetradugi [14.3K]

I'm guessing you want to know the circumference of a circle with a 20 yard radius or circumference?

circumference = 2 * PI * radius = 2 * PI * 20 = 125.66

circumference = PI * diameter = PI * 20 = 62.83

Identify the independent and dependent quantities and their units.David rode his bike to the park. After staying at the park for

Nitella [24]

when the time is between 0 and 15 minutes, the distance depends on the time on a relation: d =(1/10)t

when the time is between 15 and 40 minutes, the distance is independent of the time, it is fixed d = 1.5 miles

when the time is between 40 and 50 minutes, the distance depends on the time on the relation: d = 1.5 + (1/10)(t - 40)
