Answer 1

Answer: [tex]\sqrt{\frac{A}{\pi } }[/tex] = r

Step-by-step explanation:

The goal in this problem is to isolate the single variable, r. The original equation is A = pir^2. The first step to attempt to get r on its own is to divide each side of the equation by pi.

A = pir^2

A/pi = pir^2/pi

A/pi = r^2

Next, find the square root of each side to get r on its own:

A/pi = r^2

sqrt(A/pi) = sqrt (r^2)

[tex]\sqrt{\frac{A}{\pi } }[/tex]  = r

1.The entry tickets at a community fair cost $5 for children and $10 for adults. On a certain day 1000 people entered in the fair and \$7,100is collected. How many adults and how many children were at the fair? Please answer

Answers

Answer:

The number of adult that were at fair are 480 adults

The number of children that were at fair are 580 children

Step-by-step explanation:

The given parameters are;

The entry tickets cost for children = $5

The entry ticket cost for adult = $10

The number of people that entered the fair on a certain day = 1,000

The amount collected for entry tickets sold = $7,100

Let 'x' represent the number of children that bought tickets and were at fair, and let 'y' represent the number of adults that bought tickets and were at the fair, we have;

x + y = 1,000...(1)

5·x + 10·y = 7,100...(2)

Making 'y' the subject of both equations gives;

For equation (1)

y = 1000 - x...(3)

For equation (2)

10·y = 7,100 - 5·x

y = (7,100 - 5·x)/10 = 710 - x/2

y = 710 - x/2...(4)

Equating both values of 'y' from equation (3) and equation (4), we have;

1000 - x = 710 - x/2

1000 - 710 = -x/2 + x = x/2

290 = x/2

x = 580

The number of children that bought tickets and were at fair = x = 580 children

From equation (3), y = 1,000 - x  = 1,000 - 580 = 420

y = 480

The number of adult that bought tickets and were at fair = y = 480 adults.

Three regular hexagons are put together to make a larger shape. The perimeter of one of the regular hexagons is 18cm. Find the perimeter of the larger shape.

Answers

Answer:

steps below

Step-by-step explanation:

2 kinds of larger shapes can be make

kind 1: 18 x 4 x 3 = 216 cm

kind 2: 18 x (5+5+4) = 252 cm

The perimeter of the larger shape formed by putting three regular hexagons together is 216 cm.

When three regular hexagons are put together to form a larger shape, they form a regular hexagon with an equilateral triangle at each end.

The perimeter of the larger shape can be calculated as follows:

Perimeter of larger shape = Perimeter of hexagon + Perimeter of equilateral triangle

Since the hexagon has six sides of equal length, its perimeter is [tex]\(6 \times 18 \, \text{cm} = 108 \, \text{cm}\)[/tex].

Each equilateral triangle has three sides of equal length, and each side of the equilateral triangle is equal to one side of the hexagon.

So, the perimeter of each equilateral triangle is [tex]\(3 \times 18 \, \text{cm} = 54 \, \text{cm}\)[/tex].

Since there are two equilateral triangles, the total perimeter contributed by the equilateral triangles is [tex]\(2 \times 54 \, \text{cm} = 108 \, \text{cm}\)[/tex].

Finally, to find the perimeter of the larger shape, add the perimeters of the hexagon and the two equilateral triangles:

Perimeter of larger shape = 108 cm + 108 cm = 216 cm

Thus, the perimeter of the larger shape is [tex]\(216 \, \text{cm}\)[/tex].

Your friend claims that she has a bag of 30 coins containing nickels, dimes,
and quarters. The total value of the 30 coins is $3. There are twice as many
nickels as there are dimes. Is your friend correct?

Answers

9514 1404 393

Answer:

  No

Step-by-step explanation:

If all 30 coins were nickels and dimes, there would be 10 dimes and 20 nickels, for a total value of $2.00. Trading a dime and 2 nickels for an equal number of quarters raises the value to $2.00 -0.10 -2(0.05) +3(0.25) = $2.55.

That is, each such trade adds $0.55 in value to the total amount. Since the original difference of $3.00 -$2.00 = $1.00 is not evenly divisible by $0.55, there cannot be twice as many nickels as dimes.

__

For 30 coins, possible numbers of {nickels, dimes, quarters} are ...

{21,2,7}, {18,6,6}, {15,10,5}, {12,14,4}, {9,18,3}, {6,22,2}, {3,26,1}, {30 dimes}

Note that we can have 1.5, 3, or 10.5 times as many nickels as dimes, but not 2 times as many.

Isaiah has $7.15 in Dimes and Nickels. He has a total of 91 coins. How many of each coin does he have? Group of answer choices dimes: 31 nickels 60 dimes: 60 nickels: 31 dimes: 52 nickels: 39 dimes: 39 nickels: 52

Answers

Answer:

Dimes = x = 52

Nickels = y = 39

Step-by-step explanation:

Let

Dimes = x

Nickels = y

x + y = 91 (1)

0.10x + 0.05y = 7.15 (2)

From (1)

x = 91 - y

Substitute x = 91 - y into (2)

0.10x + 0.05y = 7.15

0.10(91 - y) + 0.05y = 7.15

9.10 - 0.10y + 0.05y = 7.15

- 0.10y + 0.05y = 7.15 - 9.10

-0.05y = -1.95

y = -1.95 / 0.05

= 39

Substitute y = 39 into (1)

x + y = 91

x + 39 = 91

x = 91 - 39

x = 52

Dimes = x = 52

Nickels = y = 39

Police chases a driver. The police is 1 mile behind the driver. The speed of the police is 90 mph, and the speed of the chased car is 85 mph. How long will it take for the police to catch up with the car?

Answers

Answer:

0.20 hour

Step-by-step explanation:

According to the problem, computation of the given data are as follows,

Speed of police = 90 mph

Speed of chased car = 85 mph

Distance to be chased = 1 mile

So, we can calculate the time to catch by using following formula:

Time required = Distance between two cars ÷ (Speed of Car A - Speed of Car B)

= 1 ÷ ( 90 - 85)

= 1 ÷ 5

= 0.20 hour
