Answer:
5 : 2
Step-by-step explanation:
Given that:
Number of gumdrops = 420
Number of chocolate bars = 280
Total Number of candies = 700
To find:
The ratio of candies to chocolate bars = ?
Solution:
First of all, let us discuss the method to find the ratio of any two quantities.
Suppose, we need to find the ratio of two numbers and
.
Then to find the ratio , we need to divide p by q and represent it in the simplest form
such that a and b can not be divided further.
Here, to find the ratio of candies to chocolate bar:
Here, we can simplify the fraction by dividing the numerator and denominator by 10 first:
Now, let us divide the numerator and denominator by 14:
So, the ratio is <em>5 : 2</em>
Answer:
70%
Step-by-step explanation:
First, convert 0.3 into a percentage;
To do so, convert it 0.3 into a fraction then multiply by 100;
0.3 into a fraction = 3/10
3/10 into a percentage =
The 10 at the bottom cancels out one zero at the top and you are left with 30.
Therefore percentage in Carlos' monthly savings is = 30%
Next, calculate the percentage NOT put in savings
percentage NOT put in savings = 100% - percentage in savings;
That is ; 100% -30% =70%
Hence, 70% of his income is not put into savings.
Answer:
y = 3x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (2, 2) ← 2 points on the line
m = =
= 3
Note the line crosses the y- axis at (0, - 4) ⇒ c = - 4
y = 3x - 4 ← equation of line
