Probablity=desiredoutcomes/totalpossibleoutcomes
see which ones fit
dimes and quarters are over 9 cents
there are 11+3 or 14 of them
total outcomes=12+9+11+3=35
probablity=14/35=2/5
probablity is 2/5
The number is 12
12 + 4 = 16
4 is a third of 12 and 12 + 4 = 16.
Answer:
The "3y" in the first term is a factor
The "9" in the second term is a coefficient
The "(7 + 2x)" in the first term is a factor
Step-by-step explanation:
Given in the question an expression
3y(7 + 2x) + 9xy - 10
- The coefficients are the numbers that multiply the variables, x and y.
<h3>Example</h3>
6y
6 is coefficient
2.Constants are terms without variables
<h3>Example</h3>
10
3.The factors in a mathematical expression are parts of the expression that are connected with multiplication.
<h3> Example</h3>
(4x+1)(3x+7)
(4x+1) and (3x+7) both are factors
Answer:
Molly will pay $13.20 for the dress
40% of $20 is the discount, $8.00
Step-by-step explanation:
multiply dress cost by % you will pay, then add 10%
$20 x .60 then add 10%
$12 is dress with coupon, and 10% of that is $1.20
$12 + $1.20 is $13.20
Answer:
0.6 liters paint will he need to cover 
Step-by-step explanation:
Direct Variation states that the two quantities are related in such a way that increase in one quantity results in a corresponding increase in the other quantity and vice versa, then such type of a variation is called a direct variation.
i.e 
It is given that the painter uses 1.2 liters of paint to cover 
This is the situation of Direct Variation: As less area cover, less liters of paint.
Let two quantities are x and y;
x represents the area covered by painter
y represents the liters uses by the painter.
Then, the ratio of any two values of y is equal to the corresponding value of x.
i.e,
or
therefore, from the given information we have;
Simplify:
Therefore, 0.5 liters paint required by the painter to cover the area
