Answer:

(b) 1:9

Step-by-step explanation:

(b) x*y : kx*ky, so 1:k² with k=3 is 1:9

(c) Assuming the rectangles get a z dimension, the volumes would have a ratio of xyz : xkykzk = xyz : xyzk³ = 1 : k³. With k=2 that is 1:8. But the z was never introduced so this is a bit inconclusive.

Question NEEDS ANSWERING

labwork [276]

The numeric value of the given expression is as follows:

121/900.

<h3>Numeric value of expression</h3>

The expression is defined as follows:

$\left(-\frac{1}{3} + 0.6\left(-\frac{1}{2}\right) + 1\right)^2$

The parenthesis take precedence. If there are more than one parenthesis, the inside one takes precedence.

The fraction equivalent of 0.6 is of 3/5, hence:

$\left(-\frac{1}{3} + \frac{3}{5}\left(-\frac{1}{2}\right) + 1\right)^2$

Solving the internal parenthesis, the expression is:

$\left(-\frac{1}{3} - \frac{3}{10} + 1\right)^2$

The least common multiple of 3, 10 and 1 is of 30, hence:

$\left(-\frac{1}{3} - \frac{3}{10} + 1\right)^2 = \left(\frac{-10 - 9 + 30}{30}\right)^2 = \left(\frac{11}{30}\right)^2$

To find the square of the fraction, we find the square of the numerator and the denominator, hence the numeric value of the expression is:

121/900.

<h3>Missing information</h3>

The expression is:

$\left(-\frac{1}{3} + 0.6\left(-\frac{1}{2}\right) + 1\right)^2$

Helpp me pleaseeeeee

Answer:

On-time Buses: 75%

Running late Buses: 13.46%

Step-by-step explanation:

Part 1: Solve for the probability of Jerry owning an "on-time" bus

Of the 48 buses that run on time, Jerry owns 36 of them. Therefore, the probability of a bus running on time being owned by Jerry will be solved with the ratio of 36 buses to 48 buses.

This is represented by the fraction 36/48.
Simplifying this fraction will give us 3/4.
Convert to a decimal and then multiply by 100 to get a percentage - 75%.

Part 2: Solve for the probability of Jerry owning a "running late" bus

Of the 52 buses that run late, Jerry owns 7 of them. Therefore, the probability of a bus running late & being owned by Jerry will be solved with the ratio of 7 buses to 52 buses.

This is represented by the fraction 7/52.
Simplifying this fraction will give us 7/52 (cannot be simplified).
Convert to a decimal and then multiply by 100 to get a percentage - 13.46%.

Name all sets square root of 27 belongs to please help me quick !

lesantik [10]

Details about all sets square root of 27 is given below.

Step-by-step explanation:

1. Square Root of 27

To an accuracy of at least . 01%, the square root of 27 is 5.196.

2. 27 = 33 = 32 * 3

sqrt(27) = sqrt(32 * 3)

= 3*sqrt(3)

sqrt(3) can't be expressed as the ratio of integers and when written as a decimal it does not terminate, so it is irrational.

Thus sqrt(27) is itself irrational.

3. Simplest form of √27

27 is not a perfect square so it does it have an exact square root.

√27 is an irrational number, but it can be written in surd form:

√27=√3×3×3.

=3√3.

4. Is 27 a perfect square number? A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 27 is about 5.196. Thus, the square root of 27 is not an integer, and therefore 27 is not a square number.

5. The number 27 can be evenly divided by 1, 3, 9 and 27, with no remainder. Since 27 cannot be divided by just 1 and 27, it is a composite number.

6. 27. All terminating decimal numbers are rational.All irrational numbers are real.

7. For 27 to be an integer, 27 has to be a whole number. Furthermore, for 27 to be an integer, you should be able to write 27 without a fractional or decimal component. 27 is a whole number that can be written without a fractional component, thus 27 is an integer.
