a group of students attend a math club half the students are boys and 4/9 of the boys have brown eyes what fraction of the group
2 answers:
From the whole group half the club are boys.
fraction of boys from the whole class = 1/2
from this fraction, 4/9th of the boys have brown eyes
therefore fraction of boys who have brown eyes
= 4/9 of 1/2
the 'of' function is used to multiply
when multiplying fractions numerators are multiplied by numerators and denominators multiplied by denominators
4/18 can be simplified by dividing the whole number by a common number
4/18 divided by 2 = 2/9
the answer is 2/9
2/9 of the club are boys with brown eyes
fraction of boys from the whole class = 1/2
from this fraction, 4/9th of the boys have brown eyes
therefore fraction of boys who have brown eyes
= 4/9 of 1/2

Let represent the depth of the miner and equipments elevator, respectively. We know that equipment elevator descends with a velocity of
feet per second, and the miners one descends with a velocity of
feet per second.
If we start counting time () when the equipment elevator begins to descend, after
seconds its depth will be
On the other hand, the miner elevator follows the same rule, but we have to use its velocity, and remember that it starts with a delay of thirty seconds:
Now, we have to wait the 30 seconds of delay, and then another 14 seconds. This means that we want to know the positions of both elevators when . Let's plug this value into the two equations:
So, the equipment elevator is 176 feet deep, and the miner elevator is 210 feet deep, and thus this is the deeper one.

Answer:
<em>The correct option will be: (b) 7 feet.</em>
Step-by-step explanation:
Suppose, the length of the garden is feet.
As the <u>shape of the garden is like a square, then the area of the garden</u> will be: feet²
Given that, the <u>area is 52 square feet</u>. So, the equation will be.......
So, the approximate length of the garden will be 7 feet.
