J = 7 × 6
j = 42
j is 7 times greater than 6, so you have to put j equal to 7 times the number 6 :)
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that the areas of the kitchen, playroom, and dining room are in the ratio 4 : 3 : 2 and that the combined area of these three rooms is 189 square feet.
Therefore, Kitchen area = 4/(4+3+2) × 189 = 4/9 × 189 = 84 square feet
Playroom area = 3/(4+3+2) × 189 = 3/9 × 189 = 63 square feet
Dining room area = 2/(4+3+2) × 189 = 2/9 × 189 = 42 square feet
<u>Answer:
</u>
An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. Time it will take to fill the pool = 748 hrs
<u>Solution:
</u>
Let x = time it will take to fill the pool
= work rate of inlet pipe
= work rate of drain pipe
Using the formulae
Volume of flow=work rate
time
Let us assume complete time of pool to fill = 1
Remaining fraction of pool to be filled = 




Time it will take to fill the pool = 748 hrs
To find the answer, we can use the angles sum of triangle, where the sum of angle of a triangle will be 180°.
In this case, we can set an equation to find the answer:
35°+52°+3(x+2) = 180°
3x + 3(2) = 180°-35°-52°
3x = 95 - 6
x = 87/3
x = 29
Therefore, x = 29.
We can then find the measure of angle C by putting the value x in the equaiton:
3((29)+2)
=29(3) + 2(3)
=87 + 6
= 93°
Therefore, angle C is 93°.
Hope It helps!
