my school is starting from this tuesday,but i cant understand online classes. i really want physical class to start but it is not safe :(

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.

Rose would be saving 50 dollars after 10 months. So you know that Rose got $10 in 0 months and $14 in the next month and again.This means that every month it adds up to another $4. If you want to find the total or 10 months keep on add 5 4 times which is 20. Then add 30 from the 0-5 months and which gives you $50. So Rose would be saving up 50 bucks in 10 months.

Answer:27.52 inches

Step-by-step explanation:

Given

Scale factor [tex]\frac{1}{64}[/tex] i.e.

[tex]\dfrac{\text{Model}}{\text{Prototype}}[/tex]

The diameter of the model tire is 0.43 inches

Scale factor = [tex]\dfrac{\text{dia. of model}}{\text{dia. of actual car}}[/tex]

[tex]\frac{1}{64}=\frac{0.43}{D}\\D=64\times 0.43=27.52\ \text{inches}[/tex]

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.

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].

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

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
