A summer camp has 720 ft of float line with which to rope off three adjacent rectangular areas of a lake for swimming​ lessons, one for each of three levels of swimming ability. A beach forms one side of the swimming areas. Suppose that the width of each area is x feet. Answer parts​ a) through ​c).

Answers

Answer 1

Step-by-step explanation:

Kindly find attached a detailed image to better understand the solution to this problem.

given that the total length of the line is 720ft

and also the line is divided into three sections

This means that the line will also be divided into three parts

720/3= 240feet so that a section will have two sides that are 240ft since the section forms a rectangular shape.

now for the other two sides

the total length of the rope is  = one length size of the rectangle+ 4 width size of the rectangle

one width size of the rope is x

then 4 width size is 4x

720=length of rectangle +4x

length of rectangle= 720-4x

area of a rectangle is =length *width

area of rectangle is =  (720-4x)*x

Hence the function A=  (720-4x)x can be used to solve for the area of the rectangle.

Marcus is buying taco shells for a party. There will be 13 adults and 17 children

There are 8 taco shells in each package. How many packages of taco shells will Marcus
need to buy in order to have enough tacos for the people attending the party?
A 7, because (13 x 3 + 17) + 8 = 7
B 28, because (13 x 17 + 3) = 8 = 28
C 80, because (13 + 17) x 8 = 3 = 80
D 15, because (13 + 17 x 4) + 8 = 15

Answers

Answer:

Tacos for adults: 13*3

Tacos for children: 17*1

Total: 39+17

=56

And in each package there will be 8 tacos

So, 56/8 = 7 = No. of tacos needed.

So the corrrect answer is A 7, because (13 x 3 + 17) + 8 = 7

.Rahul and his wife work in Mohan's farm. The Government has declared that the farm workers should be paid Rs. 71 for a day's work. But the land lord, Mohan pays Rs. 60 for Rahul and Rs.55 to his wife. If Rahul works for 55 days and his wife for 40 days, what amount of money will they earn together?

Answers

Answer:

Rs. 5500

Step-by-step explanation:

The government has declared that farm workers should be paid Rs. 71 for a day's work

The landlord Mohan pays Rahul Rs. 60 and pays Rs. 55 to his wife

Rahul works for 55 days

= 60 × 55

= Rs. 3,300

His wife works for 40 days

= 55 ×40

= Rs. 2,200

Therefore the total amount of money earned together can be calculated as follows

= 3300 + 2200

= Rs. 5500

Hence they will earn Rs. 5500 together

Mr. Gaines is catering his company picnic. He will pay $18.45 for 3 people to eat the barbecue lunch. At this rate, how many people can Mr. Gaines afford to feed on a budget of $1,850.00

Answers

Answer: 300 people

Step-by-step explanation:

From the question, we are informed that Mr. Gaines is catering his company picnic and he will pay $18.45 for 3 people to eat the barbecue lunch. This means the cost per person will be:

= $18.45/3

= $6.15

For $1850, the number of people that Me Gaines can feed will be:

= $1850/$6.15

= 300 people

Which of the following statements is TRUE about parallel lines pq and rs?

a° and c° are alternate interior angles
a° and c° are alternate exterior angles
a° and c° are corresponding angles
a° and c° are vertical angles

Answers

Answer:

a and c are alternate interior angles

For the parallel lines pq and rs a° and c° are alternate interior angles. Option A is correct.

What are parallel lines?

Parallel lines are defined as identical lines with identical orientations, parallel lines never intersect each other but meet at infinity.

Here,
When two parallel lines is intersect by a transversal line then the angles made facing the region between the parallel lines are said to be interior angles, And as we know that alternate angles for parallel lines are always equal. So a° and c° are alternate interior angles.

Thus, a° and c° are alternate interior angles.
