ANSWER

C. 64.29

EXPLANATION

The bigger right triangle is similar to the smaller right triangle, therefore

$\frac{30}{14} = \frac{z}{30}$

Multiply both sides by 30;

$30 \times \frac{30}{14} = \frac{z}{30} \times 30$

Simplify

$z = \frac{900}{14}$

$z = 64.28571429$

We correct to the nearest hundredthth to obtain,

$z = 64.29$

The correct choice is C.

Kailey wrote 8,912,000 in scientific notation as 89.12 times 10 Superscript 5. Which statement best describes Kailey's work? Kai

hodyreva [135]

Answer:

D. Kailey is not correct: $89.12 \times 10^5$ is not written in scientific notation.

Step-by-step explanation:

We have been given that Kailey wrote 8,912,000 in scientific notation as $89.12 \times 10^5$ . We are asked to choose the statement that best describes Kailey's work.

We know that to convert a number into scientific notation, we write the given number as product of two numbers. One factor is a number between 1 and 10, while the 2nd factor is power of 10.

Upon looking at $89.12 \times 10^5$ , we can see that 1st factor is 89.10, which is greater than 10. This means that Kailey did not write 8,912,000 in scientific notation.

Therefore, option D is correct choice.

Nesterboy [21]

Answer:

Solution,

X=8

y=4

Now,

 $\frac{x + 10}{y + 5} \\ = \frac{8 + 10}{4 + 5} \\ = \frac{18}{9} \\ = 2$
