Let
x----------> <span>the length of the room
y----------> </span><span>the width of the room
we know that
x*y=120---------> equation 1
y=(5/6)x--------> equation 2
substitute 2 in 1
x*[(5/6)x]=120------> (5/6)x</span>²=120-----> x²=120*6/5-----> x²=144
<span>x=12 ft
y=(5/6)*12-----> y=10 ft
the answer is
</span><span>the dimensions of Kamal’s bedroom are
</span>the length of the room is 12 ft
the width of the room is 10 ft<span>
</span>
Answer:
x = 0 and y = 3
Step-by-step explanation:
Using elimination method, we can solve for x and y in the simultaneous equation
y = 2x + 3 .................................eqn 1
y = -3x + 3 .................................eqn 2
multiply equation 1 by 3 and equation 2 by 2, then we will have
(y = 2x + 3) × 3
(y = -3x + 3) × 2
3y = 6x + 9 ...............................eqn 3
2y = -6x + 6 ................................eqn 4
Add eqn 3 and 4 together and we will eliminate x and have
5y = 15
Divide both sides by 5, and we will have
y = 3
To solve for x, substitute 3 for y in eqn 1
y = 2x + 3
3 = 2x + 3
collect like terms
3 - 3 = 2x
0 = 2x
Therefore x = 0
Answer:
The answer is 8.91 or 8.9
Step-by-step explanation:
SInce the circumference is 56, you'll divide it by pi or 3.14. It's as if you're doing it backwards, but not always. After you divide it by 3.14, you'll get your diameter, or in this case, 17.8. Divide the diameter by 2 because the diameter is twice the radius. Eventually your final answer will be 8.91 or 8.9
Answer:
6224 Brand X residents and 9335 Brand Y residents
Step-by-step explanation:
Total number of residents in the survey=15559
Residents that prefer Brand X=40%
Residents that prefer Brand Y=60%
<u>Population sample?</u>
Residents that prefer Brand X= 40/100 ×15559 =6223.6⇒6224 residents
Residents that prefer Brand Y= 60/100 × 15559 =9335.4⇒⇒9335 residents
Answer:
Step-by-step explanation:
Given that sale of grills increase 6% per year
CUrrent sale of grills this year = 3300
So in the first year sales would increase by 3300(6%)
Total sales in the I year =3300+3300(6%)
This will be again increasing by 6% in II year and so on.
Hence we have
every year 3300 increases by 6% compoundly
So
No of sales in t year
=
In 6th year sale
s(6) =
