The distance between City A and City B is 500 miles. A length of 1.8 feet represents this distance on a certain wall map. City C
Ratling [72]

Answer: 800 miles

Step-by-step explanation:

Let the actual distance between City C and City​ D be represented by x.

The information given in the question can be formed into an equation as:

1.8 feet / 2.88 feet = 500 miles / x

Cross multiply

1.8 × x = 500 × 2.88

1.8x = 1440

x = 1440/1.8

x = 800

Therefore, the actual distance between City C and City​ D is 800 miles.

Chloe drew a triangle with side lengths of 30 centimeters, 24 centimeters, and 18 centimeters. Juan drew a triangle with side le
vlada-n [284]

Answer:

A and B

Step-by-step explanation:

Each side in Chloe's triangle is 1.5 times the length of each side in Juan's triangle.  Thus, they are 'similar' by the <u>math </u>definition of that word, by the SSS Rule for Similar Triangles.

That means they are different only in size. So, their angle measures are the same and they are the same shape.

A and B are true.

C is never true, because the sum of all 3 angles in a triangle is always 180°.

D is not true, because they are similar.

Ralph chase invested $85000 at an interest of 10% and $70000 at an interest of 8%

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

Let a represent the amount invested at interest of 10% and b represent the amount invested at 8%, hence:

a + b = 155000    (1)

Also:

0.1a + 0.08b = 14100    (2)

From both equations:

a = 85000, b = 70000

Ralph chase invested $85000 at an interest of 10% and $70000 at an interest of 8%
