Answer:

280 adult tickets

130 student tickets

190 children tickets

were sold at the concert

Step-by-step explanation:

Let the number of students be s , adults a and children c

Total 600;

Thus;

a + s + c = 600 •••••••(i)

let us look at revenue

Revenue = number * ticket price

For adults; a * 7 = $7a

For students ; s * $3 = $3s

For children; c * $2 = $2c

Total is 3150

thus;

7a + 3s + 2c = 3150 ••••••••(ii)

150 more adults than students;

a = s + 150 ••••••(iii)

Substitute iii into ii and i

into ii

7(s + 150) + 3s + 2c = 3150

7s + 1050 + 3s + 2c = 3150

9c + 3s = 3150-1050

9c + 3s = 2,100 •••••••(x)

Substitute into i

a + s + c = 600

s + 150 + s + c = 600

2s + c = 600 - 150

2s + c = 450

c = 450 - 2s ••••••(xx)

Now substitute xx into x

9(450-2s) + 3s = 2100

= 4050-18s + 3s = 2100

4050-2100 = 18s - 3s

15s = 1950

s = 1950/15

s = 130

c = 450 -2s

c = 450 - 2(130)

c = 450 - 260

c = 190

a = 150 + s

a = 150 + 130

a = 280

Answer:

Walmart

Step-by-step explanation:

It is given that,

Jonathan wants to buy his whole basketball team new clothes.

On Amazon there is a sell for 11 shirts for $145.23

The cost of 1 shirt on amazon:

[tex]C=\dfrac{145.23}{11}=\$13.20[/tex]

On Walmart sell for 23 shirts for $212.19.

The cost of 1 shirt on Walmart:

[tex]C=\dfrac{212.19}{23}=\$9.225[/tex]

Cost of 1 shirt on Amazon is $13.20 and on Walmart is $9.225. It is clear that on Walmart it is better to buy for $9.225.

Answer: 6:19

Step-by-step explanation:

Students playing basketball is 12

Students playing football is 38

12/38

Since 2 is a common factor of both 12 and 38. Therefore 12 and 38 are divisible by 2

Answer:

80

Step-by-step explanation:

I just took the test

Answer:

3^6

Step-by-step explanation:

Answer:

3-16 is your answer

Answer:

The answer is "12"

Step-by-step explanation:

Let f(x) be the function, where x specified in a certain section by the series of queries that have been addressed also as function.

[tex]\to f(12)=18[/tex] it implies, that even a test the person gets 18 points to packed up x queries. Its right series of issues were also:

[tex]\to f(x) = f(12)[/tex]

Therefore x = 12, The correct number of questions in the segment.

Answer:

There are 5 orders of watermelon for every 9 orders of french fries

Step-by-step explanation:

9:14 is french fries: total side dishes (including french fries)

So, the ratio of french fries to watermelon would be 9:5

• x+y = 4

• 2x+3y= 6.

• x and y.

• x+ y = 4

=> x = 4 - y

put x in :

• 2x + 3y = 6

=> 2 (4-y)+3y = 6

=> 8 - 2y +3y = 6

=> y = 6 - 8

=> y = -2 .

Now, put y in x+y= 4.

=> x+(-2)= 4

=> x - 2 = 4

=> x = 4+2

=> x= 6.

Hence, the value of x is 6 and y is -2.

I hope it will help you.

Answer:

a.) 0.468

b.) -0.075

c.) 0

Step-by-step explanation:

Given the distribution :

Z~N(μ = 0,σ = 1)

Distribution = normal

Mean (μ) = 0

Standard deviation (σ) = 1

a) Find x so that P(Z ≤ x) = 68%

Using the z probability calculator : Zscore corresponding to 68% = 0.68 = 0.468

Usingbthe relation :

Zscore = (x - m) / σ

0.468 = (x - 0) / 1

0.468 = x - 0

x = 0.468

b) Find the data value x at the 47th percentile

47th percentile = Zscore of - 0.075

Zscore = (x - m) / σ

-0.075 = (x - 0) / 1

-0.075 = x - 0

x = -0.075

c) Find the data value x at the 50th percentile

50th percentile = Zscore of 0.0

Zscore = (x - m) / σ

0.0 = (x - 0) / 1

0.0 = x - 0

x = 0

Answer:

3886.53 [tex]m^{2}[/tex]

Step-by-step explanation:

The running track consist of two semicircles and a rectangle.

So that;

Diameter of the semicircles = width of the rectangle = 73 m

radius = [tex]\frac{diameter}{2}[/tex]

          = [tex]\frac{73}{2}[/tex]

          = 36.5 m

But the two semicircles form a circle, so that;

Circumference of a circle = 2[tex]\pi[/tex]r

Circumference of the circle formed by the semicircles = 2 x [tex]\frac{22}{7}[/tex] x 36.5

                                          = 229.43 m

Thus,

length of the running track = circumference of the circle formed + length of the two sides of the rectangle

                                             = 229.43 + 84.39 + 84.39

                                             = 398.21 m

The length of the running track is 398.21 m.

Therefore;

Area of the running track = length x width

                                         = 398.21 x 9.76

                                         = 3886.5296

The area of the running track is 3886.53 [tex]m^{2}[/tex].

Answer:

The temperature dropped 14 degrees.

Step-by-step explanation: x = 14

x + (-5)= 9

The absolute value (distance from zero) of -5 is 5.

The absolute value of 9 is 9.

To find the drop in temperature, add the absolute values of both numbers.

Answer:

y=1/5(x+8)-9

Step-by-step explanation:

Point Slope Formula: y=m(x-x1)+y

y=1/5(x+8)-9

Answer:

[tex]y+9=\frac{1}{5} (x+8)[/tex]

Step-by-step explanation:

We are given that a line has a slope (m) of 1/5, and passes through the point (-8, -9).

We want to write the equation of this line in point-slope form.

Point-slope form is given as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1,y_1)[/tex] is a point.

As we are given both the slope and the point, we can plug those values into the equation.

Starting with the slope, we can replace m with 1/5.

[tex]y-y_1=\frac{1}{5} (x-x_1)[/tex]

Now, substitute -8 as [tex]x_1[/tex] and -9 as [tex]y_1[/tex]. We get:

[tex]y--9=\frac{1}{5} (x--8)[/tex]

This can be simplified to:

[tex]y+9=\frac{1}{5} (x+8)[/tex]

Answer:

165.43

Step-by-step explanation:

So...

14.2*11.65=165.43

Answer:

8 signs

Step-by-step explanation:

since there is one every 1/4, multiply that by 4 so it equals one mile. since there are 2 miles, multiply it by 2, then you get 8. I know this is the answer, I hope I helped you in time! :)
