<span>If we are to express both ratios in their simplest form,
we will have the ratio of Michael’s lemonade is 1:4 and that of Sondra is 1:3.
The denominator that can be used in order to compare the ratios is that which
can be divided by both ratios. For example, we have 12 as a denominator. The
ratios can be expressed as 3/12 and 4/12. Also, the denominator can be 24 such
that the ratios can be expressed as 6/24 and 8/24. </span>
Answer:
Pam is 51.
Jan is 48.
Step-by-step explanation:
Pam is 3 years older than Jan so her age is x + 3 where x is Jan's age. When we add Pam's age and Jan's age, the sum equals 99.
So x + x+3 = 99. Solve for x.
2x+3 = 99
2x=96
x= 48
So Jan is 48 years old. This means Pam is 51.
Answer:
When we have a rectangle of length L and width W, the area is calculated as:
A = W*L
In this case, W = x, and the area is:
A = 2*x
Then we must have L = 2.
We know that the area of the window and the frame (together) is:
a = 2*x^2 + 12*x + 16
The area of the frame alone, will be equal to the difference between the area of both objects (a) and the area of the window alone (A)
area of the frame = a - A
= (2*x^2 + 12*x + 16) - (2*x) = (2*x^2 + 10*x + 16)
This is the area of the frame
the area and circumference ones are correct. a quadrilateral has 4 sides, so that one is incorrect. hope this helps!
