Answer:
23x + 18y = 1446
x + y = 72
Step-by-step explanation:
The bakery made $1446 total. We represent this as the cost of each cake ($23) times the number of cakes sold (x) plus the cost of each dozen cupcakes ($18) times the number of cupcakes sold (y).
Thus, 23x +18y = $1446.
The bakery sold 72 items total. We represent this as the number of cakes sold (x) plus the number of each dozen cupcakes sold (y).
Thus, x + y = 72.
The four angles are congruet. So each angle is 90°.
So the figure is a rectangle. It could be a square but not necessarily. You can consider a square a special case of rectangle.
The four angles of a rectangle are congruent. And the opposite sides are congruent.
The four angles of a square are congruent. The opposite sides are congruent, furthermore the four sides are congruent.
Answer:
(a)
degree is 4
it is binomial
(b)
degree is 2
it is trinomial
(c)
degree is 3
it is monomial
Step-by-step explanation:
(a)
we are given function as
Degree:
we know that degree is highest exponent value
so, degree is 4
Number of terms:
we can see that there are two terms
so, it is binomial
(b)
we are given function as
Degree:
we know that degree is highest exponent value
so, degree is 2
Number of terms:
we can see that there are three terms
so, it is trinomial
(c)
we are given function as
Degree:
we know that degree is highest exponent value
so, degree is 3
Number of terms:
we can see that there are one term
so, it is monomial
Answer: 52
Step-by-step explanation:
You want log √(9/25). Recognizing that √9 = 3 and that √25 = 5, we get
log 3/5, which by rules of logs comes out to log 3 - log 5.
To four decimal places:
log 3 - log 5 = 0.4771 - 0.6990, or -0.2218.
