1 answer:

6 0

The answer is 5x-59
To get this answer you have to follow pemdas and remember you can’t add variables to non variables, so you just expand the equation
As an example
5x + 6 -2x +7

You would get
13-3x

In the Stone Ridge apartment complex 35% of the apartments have one bedroom if there are 49 one bedroom apartments what is the t

Softa [21]

Answer:

140

Step-by-step explanation:

Given:

In the Stone Ridge apartment complex 35% of the apartments have one bedroom.

If there are 49 one bedroom apartments.

Question asked:

What is the total number of apartments at Stone ridge ?

Solution:

<u>Let total number of apartments at Stone ridge</u> = $x$

Now according to question:

35% of the total apartments having one bedroom = 49

$35\%\ of x = 49$

$\frac{35}{100}\times x = 49$

$\frac{35x}{100} = 49$

By cross multiplication:

$35x = 49\times100\\35x= 4900\\$

By dividing both sides by 35

$\frac{35x}{35} = \frac{4900}{35} \\x = 140$

Therefore, total number of apartments at Stone ridge is 140

The equation y - 3x - 5 = 0 when written in slope-intercept form is:

quester [9]

Answer:

y = 3x + 5

Step-by-step explanation:

The zero seems to be a place holder to mess you up. Just ignore that it doesn't do anything. Add -3x and -5 to the both sides to create y = 3x + 5

The scale of a map is given as 1 : 20000000. Two cities are 6 cm apart on the map. Find the actual distance between them.

larisa [96]

Answer:

<em>The actual distance between the cities is 1,200 Km</em>

Step-by-step explanation:

<u>Scaling </u>

Objects can be represented in a reduced or augmented size by using scaling which is multiplying or dividing real dimensions by a constant factor. We use scaling when representing geographic locations on a map.

We are given the scale on a map as 1:20,000,000.

Two cities are 6 cm on the map. The actual distance is obtained by multiplying:

6 * 20,000,000 = 120,000,000 cm

Divide by 100 to convert to meters and by 1,000 to convert to km 120,000,000/100/1,000=1,200 Km

The actual distance between the cities is 1,200 Km

Using translation concepts, it is found that the transformations to create function d are given as follows:

Horizontal shift right 1 unit.

Vertical shift up 5 units.

Frequency multiplied by 2.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the parent cosine function is given by:

f(x) = cos(x).

The translated function is given by:

d(x) = cos(2x - 1) + 5.

Which means that:

1 was subtracted in the domain, hence the was a horizontal shift right 1 unit.

5 was added in the range, hence there was a vertical shift up 5 units.

There was a multiplication by 2 in the domain, hence the frequency is multiplied by 2.
