Answer:
B. 28 hours
Step-by-step explanation:
GIVEN :- <em>Time taken by family to travel 600 km is 8 hours</em>
CALCULATIONS :-
<em>To calculate the time to travel 2100 km, we need to calculate distance traveled in 1 hour</em>
<em>Distance traveled in 1 hour = 600 km ÷ 8</em>
<em> = 75 km</em>
<em>Time required to travel 2100 km = 2100 ÷ 75</em>
<em> = </em><em>28 hours</em>
Therefore time required to travel 2100 km is 28 hours.
The degree of an individual term of a polynomial is the exponent of its variable; the exponents of the terms of this polynomial are, in order, 5, 4, 2, and 7. The degree of the polynomial is the highest degree of any of the terms; in this case, it is 7.
Answer:
1 1/3
Step-by-step explanation:
Solve. Change the division sign into a multiplication, and flip the second fraction:
(8/15)/(2/5) = (8/15) x (5/2)
Multiply across:
(8 x 5)/(15 x 2) = (40)/(30)
Simplify. Divide common factors:
(40/30)/(10/10) = 4/3
4/3 or 1 1/3 is your answer.

Answer:
The equation representing how old Monique son is 
Step-by-step explanation:
From the given information:
A linear function can be used to represent the constant growth rate of Monique Son.
i.e.
where;
= initial height of Monique's son
= growth rate (in)
t = time
So, the average boy grows approximately 2 5/8 inches in a year.
i.e.
Then; from the equation
The height of the son as a function of the age can now be expressed as:
Then:
Making t the subject;
and the age of the son i.e. ( a (in years)) is:
a = 2 + t
So;
SO;
if q (growth rate) = 50 inches tall
Then;
a = 2 + 6.095
a = 8.095 years
a ≅ 8 years
i.e.
Monique son will be 8 years at the time Monique is 50 inches tall.
The perimeter of a rectangle is 30 inches. If its length is three times its width, find the dimensions. 30 inches=2(L+W) Divide each side by 2. 15 inches=L+W Substitute for L.
