Five out of every nine pencils are yellow. You can make a fraction for this:
You have 45 pencils. To find the amount of yellow pencils, multiply the fraction by 45. First set up the equation:
Make 45 as a fraction so that you'll be multiplying fractions together. It will also make it easier.
To write a whole number as a fraction, <em>ALWAYS</em> make the whole number the denominator and 1 as the numerator.
Here is the "new equation":
Multiply. You multiply the numerators and denominators together.
That means <u>25</u> pencils are yellow
Answer:
A = 187.5L - L^2
So,
g(l) = 187.5l - l^2
Step-by-step explanation:
The perimeter of a rectangle is given by:
P = 2(L + B)
Where P = perimeter
L = Length
B = Width
Making B the subject of formula, we have;
B = P/2 - L ......1
The area of a rectangle is:
A = L × B ........2
Substituting equation 1 to 2.
A = L × (P/2 - L)
A = LP/2 - L^2 .......3
Given that the perimeter P = 375 inches
A = L(375)/2 - L^2
A = 187.5L - L^2
So,
g(l) = 187.5l - l^2
Answer:
Perimeter = sum of length of all sides = 8 + 3 + 10 + 11 = 32
Area = (base1 + base2) x height/2 = (3 + 11) x 7/2 = 49
Hope this helps!
