Adam’s house is 2 centimeters from Juan’s house on a map. If each centimeter on the map represents 6 kilometers, how far apart are the two houses?

Answer:

x=30°

Step-by-step explanation:

To find the value of x we need atleast 2 other angles, and we do we have one  70, but we need to get another angle from the info given outside the triangle,

Notice, the angle beside 100 can be found by simply subtracting 180-100

(since angles are on a straight line [Supplementary angles]

So, the angle is 80

Now, we know that the angles inside a triangle add up to 180

So basically, to find x:

70+80+x = 180

150+x = 180

x = 180-150

x=30°

Hoep this helps!

The ratio of students who study French to students who don't is 4 : 11

Ratio shows the relationship that exists between two or more numbers. It displays the number of times a value is contained in another value

The fraction of students that study a language = 2/3

fraction of students that study French = ×

Fraction of students that do not study French = 1 -

The ratio ;

÷

×

= 4 : 11

Answer: 4:11

Step-by-step explanation:

Given : Fraction of students study a language

Let x be the number of students in the school.

Then , No. of students study a language

Fraction of students who study a language study French  

No. of of students who study a language study French  

No. of students study French =

Then, the number of students do not study French =

Now, the ratio of student who study French to students who do not study French:-

Hence, the required answer =  4:11
