Answer:

12=0.005×w
the number is 2400

Step-by-step explanation:

An appropriate representation of the problem can be had by using a variable to represent "what number" and then using the math equivalent symbols for the English words. If "what number" is represented by w, then we want to translate ...

0.5% of w is 12 . . . . English

0.005 × w = 12 . . . . . . . matches choice 1

This can be solved by multiplying by 200

200(0.005w) = 200(12)

w = 2400

The number is 2400.

Tommy wished he practiced more before his violin concert. If he had practiced 1 1/2 more hours one week, he would have averaged

Nimfa-mama [501]

Answer:

30.5 hours

Step-by-step explanation:

If he were to average 8 hours PER week for 4 weeks, his total sum would have been:

8 * 4 = 32 hours

But he fell short of it. By how much?

By $1\frac{1}{2}$ hours!

So, he practiced 1 1/2 hours LESS THAN 32 hours, so his practice time is:

$32-1\frac{1}{2}\\=32-1.5\\=30.5\\=30\frac{1}{2}$

So, he practiced 30.5 hours in the 4 weeks

What is the value of x to the nearest tenth? A)7.2 B)4.8 C)12.0 D)9.2

Anika [276]

Answer:

x = 7.2

Step-by-step explanation:

a² + b² = c²

x² + (19.2/2)² = (24/2)²

x² + 9.6² = 12²

Subtract 9.6² from both sides

x² = 12² - 9.6²

x² = 51.84

x = 7.2

Using these coordinates, find the slope. (0, -6), (3, -2)

seropon [69]

Answer:

The slope between the points (0, -6) and (3, -2) will be:

$m=\frac{4}{3}$

Step-by-step explanation:

Given the points

(0, -6)

(3, -2)

The slope between the points (0, -6) and (3, -2) will be:

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(0,\:-6\right),\:\left(x_2,\:y_2\right)=\left(3,\:-2\right)$

$m=\frac{-2-\left(-6\right)}{3-0}$

$m=\frac{4}{3}$

Therefore, the slope between the points (0, -6) and (3, -2) will be:

$m=\frac{4}{3}$
