Mathematics
1 answer:
dangina [55]3 years ago
8 0

Answer:

In bold.

Step-by-step explanation:

6/6 = 9/a

So a = 9.

6/c = a/4.5

6/c = 9/4.5 = 2

So c = 3.

By similar triangles:

d/5 = 6/ (6+6+3)

d/5 = 6/15 = 2/5

So d = 2.

Also by similar triangles

b/5 = 12/15 = 4/5

So b = 4.

Does x+y=1 have an x-intercept of (1,0) and y intercept of (0,1)?
aivan3 [116]

Answer:

Yes

Step-by-step explanation:

To find the y intercept of this formula, you first need to convert it into slope intercept form.

x+y=1

y=-x+1

Here, the slope is negative 1 and the y intercept is (0,1). If you imagine the line with a slope of negative 1, it will indeed cross the x axis at (1,0). Hope this helps!

Write a function numberofpennies() that returns the total number of pennies given a number of dollars and (optionally) a number
ElenaW [278]
What language are you writing this in? C? Javascript? Java? Are you allow to have parameters? 
The general idea should be the same. Since 1 dollar  = 100 pennies, we should write something like...

Java:
public static double numberofpennies(double dollars, double penny) {         
           double sum = 0;                  

           // The amount of pennies that dollar represents       
           double converted = dollars * 100.0;                  

           sum = converted + penny;
         
           return sum;   
}
Note: You should probably place this question under the category computer and technology instead of math. Also, this is just an example of what you could possibly write. What parameters you are allowed to use, what type (double? int? etc?) of pennies are you allowed to return, etc. depends on how you write it.
