Answer:
Quintic Trinomial (2nd option)
Step-by-step explanation:
We know that this is a quintic polynomial because the degrees add up to 5. If we expand the polynomial, we have 
So, there are 3 terms, which is a trinomial.
a.
f = total cab fare
m = distance travelled
f = 2 + 0.50m
b.
7.50 = 2 + 0.50m
c.
7.50 = 2 + 0.50m
7.50 - 2 = 0.50m
5.50 = 0.50m
5.50/0.50 = m
m = 11
Sara travelled 11 miles.
d.
f = 2 + 0.50m
f = 2 + 0.50 x 10
f = 2 + 5
f = 7
When the cab fare is over $7.00 on the holidays, $1 is discounted off the fare.
e.
Yes, Lupe traveled more than 10 miles. (refer to calculations used in c.)
Joey has 21 socks all in all. Out of them, there are 10 dress socks and 13 brown socks. There are 7 brown dress socks. The probability,
P (brown or dress) = P (brown) + P (dress) - P (brown and dress)
Substituting,
P(brown or dress) = 13/21 + 10/21 - 7/21 = 16/21
Thus, the answer is 16/21.
24 is the LCD of 5/12 and 3/8
Answer:
In this question the value of x is 45.
Step-by-step explanation:
given that :
x/5-7=2 and x=?
solve : x/5-7=2
x-7(5)/5=2 taking L.C.M
x-35/5=2
x-35=2*5 multiply by 5
x-35=10
x=10+35
x=45.
