Answer:
243 people
Step-by-step explanation:
Kelli is searching for a new daycare center for her child. At Lori's Local Daycare, there is a ratio of 2 caretakers for every 7 children. If there are 189 total children, then how many people are at the daycare facility?
The ratio is given as:
Caretakers : Children
2 : 7
= In fraction = 2/7
If there are 189 total children, then how many people are at the daycare facility?
Step 1
We calculate the number of caretakers is there are 189 children
7 children = 2 caretakeras
189 children = x
Cross Multiply
7x = 189 × 2
x = 189 × 2/7
x = 54 caretakers
Step 2
The total number of people at the daycare
= 189 children + 54 caretakers
= 243 people
a) The equations to determine the length and the width of the rug are
l = 4 + w and l × w = 21
b) The enlarged rug's area = 60 square feet
Step-by-step explanation:
Step 1 :
Let l be the length and w represent the width of the rectangular rug
Given the area = 21 square feet.
So l × w = 21
Also given, the length is 4 feet longer than the width .
So we have
l = 4 + w
Step 2 :
Using the above 2 equations we have
(4+w)w = 21
w² + 4 w - 21 = 0
(w+7)(w-3) = 0
=> w = -7 or w = 3
Since w is the width of the rug, we take the positive value w = 3 as the width
So w = 3 feet
So
l = 4 + w = 4 +3 = 7 feet
Step 3 :
When a 1.5 foot border is added all the way round the rug, the length and width are increased by 3 feet (1.5 feet on both sides) the rug's enlarged length and the rug's enlarged width is
l = 7 + 3 = 10
w = 3 + 3 = 6
The enlarged rug's area = 10 × 6 = 60 square feet
Step 4 :
Answer :
The equations to determine the length and the width of the rug are
l = 4 + w and l × w = 21
The enlarged rug's area = 60 square feet
It is 2353 because if you round it to the nearest hundreds also, it will be 2400
