To solve this problem, we can use a system of equations to find the number of people who paid $14 for reserved seats and the number of people who paid $5 for general admission.

To solve this problem, we can use a system of equations. Let's say the number of people who paid $14 for reserved seats is 'x', and the number of people who paid $5 for general admission is 'y'.

We know that the total number of people who attended the ballgame is 31,000, so we can write the equation:

x + y = 31,000

We also know that the total receipts from the day were $200,000, so we can write another equation:

14x + 5y = 200,000

Now we can solve this system of equations to find the values of 'x' and 'y'.

Multiplying the first equation by 5, we can eliminate 'y' by subtracting the second equation from it:

5x + 5y = 155,000

-(14x + 5y = 200,000)

Simplifying, we get:

-9x = -45,000

Dividing both sides of the equation by -9, we find that 'x' = 5,000.

Substituting this value back into the first equation, we can solve for 'y':

5,000 + y = 31,000

Simplifying, we get 'y' = 26,000.

Therefore, 5,000 people paid $14 for reserved seats and 26,000 people paid $5 for general admission.

Answer:

9) 22 - 5(6v - 1) = -63

22 - 30v + 5 = -63

27 - 30v = -63

-30v = -90

v = 3

10) 18x - (8x - 7) = 67

18x - 8x + 7 = 67

10x = 60

x = 7

11) 8(-2x - 4) + 12 = -52

8(-2x - 4) = -64

-2x - 4 = -8

-2x = -4

x = 2

Kade has 1/6 cup of salad dressing left after using some on a salad. We found this by converting 2/3 cup to 4/6 cup and then subtracting it from the 5/6 cup he initially had.

To find out how much salad dressing Kade has left after using some on a salad, we need to subtract the amount used from the total amount he made. Kade made 5/6 cup of salad dressing and used 2/3 cup on a salad. To perform the subtraction, both fractions need a common denominator. The smallest common denominator for 6 and 3 is 6. The fraction 2/3 can be converted to 4/6 so that both fractions have the same denominator. Now we can subtract:

Hence, Kade has 1/6 cup of salad dressing left after using it on the salad.

Answer:

Multiply [tex]2\frac{1}{2}[/tex] by [tex]3[/tex] and then add [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

we know that

using proportion

[tex]\frac{(3/4)}{1}\frac{in}{week}=\frac{x}{3}\frac{in}{weeks} \\ \\x=3*(3/4)\\ \\x=9/4\ in[/tex]

Find the height of the plant in [tex]3[/tex] weeks

[tex]2\frac{1}{2} +\frac{9}{4}=\frac{5}{2} +\frac{9}{4}\\ \\=\frac{19}{4}\ in[/tex]

therefore

The incorrect method is

Multiply [tex]2\frac{1}{2}[/tex] by [tex]3[/tex] and then add [tex]\frac{3}{4}[/tex]

because

[tex]2\frac{1}{2}*3+\frac{3}{4}=\frac{15}{2}+\frac{3}{4}\\ \\=\frac{33}{4}\ in[/tex]

Histogram options for golf scores: (a) 3,9,8,9,2; (b) 5,7,10,7,4; (c) 4,8,9,8,3; (d) 5,8,9,8,5. Correct choice (d) accurately represents the frequency distribution of scores in ten-point intervals.

To create a histogram with ten-point intervals for the given golf scores, we need to organize the scores into ranges and determine the frequency of scores within each range. Let's examine each option:

a. 70-80: 3 scores, 80-90: 9 scores, 90-100: 8 scores, 100-110: 9 scores, 110-120: 2 scores.

b. 70-80: 5 scores, 80-90: 7 scores, 90-100: 10 scores, 100-110: 7 scores, 110-120: 4 scores.

c. 70-80: 4 scores, 80-90: 8 scores, 90-100: 9 scores, 100-110: 8 scores, 110-120: 3 scores.

d. 70-80: 5 scores, 80-90: 8 scores, 90-100: 9 scores, 100-110: 8 scores, 110-120: 5 scores.

The correct histogram is option (d) with scores in the 70-80, 80-90, 90-100, 100-110, and 110-120 ranges having frequencies of 5, 8, 9, 8, and 5, respectively. This accurately represents the distribution of golf scores in ten-point intervals among the members of the Belmont Country Club.

To simplify the expression (3x^4y^-5)^3, apply the power rule to each term, calculate the result, and combine them. The simplified form is 27x^12y^-15.

How to Simplify the Expression (3x^4y^-5)^3:

Let's simplify the given expression step by step:

(a^m * b^n)^p = a^(m*p) * b^(n*p)

So, (3x^4y^-5)^3 becomes:

(3^3) * (x^(4*3)) * (y^(-5*3))

Putting it all together, we get:

27x^12y^-15

In conclusion, the simplified form of (3x^4y^-5)^3 is 27x^12.y^-15.

The parabola will become narrower, the correct option is B.

For a function f(x), we define a vertical stretch of scale factor k as:

g(x) = k*f(x).

If k > 1, we have a stretch, if 0 < k < 1, we have a contraction.

In this case, we have:

So we have a vertical stretch of scale factor 2, this means that we are stretching our function vertically, so it will become narrower, meaning that the correct option is B.

Answer:

Step-by-step explanation:

Answer:

Perimeter of given triangle is ( 9.8x + 1.1y + 9.9z ) centimeters.

Step-by-step explanation:

Given : A triangle has a side lengths of (5.5x + 6.2y) centimeters, (4.3x+8.3z) centimeters and (1.6z -5.1y) centimeters  

We have to find the expression  that represents the perimeter (in centimeters)

of the triangle.

Perimeter of a figure is defined as the sum of all the sides.

Since given figure is triangle so perimeter of triangle is the sum of all the sides.

Given side lengths are

(5.5x + 6.2y) , (4.3x + 8.3z) and (1.6z -5.1y)

Thus, perimeter = (5.5x + 6.2y)  + (4.3x + 8.3z) + (1.6z - 5.1y)

Perimeter = 5.5x + 6.2y + 4.3x + 8.3z + 1.6z - 5.1y

LIKE TERMS are term with same variables.

Rearrange, we get

Perimeter = 5.5x + 4.3x + 6.2y - 5.1y + 8.3z + 1.6z

Adding like terms, we get,

Perimeter = (5.5 + 4.3)x + (6.2 - 5.1)y + (8.3 + 1.6)z

Perimeter = (9.8)x + (1.1)y + (9.9)z

Thus, Perimeter of given triangle is 9.8x + 1.1y + 9.9z centimeters.

The best estimate of the total cast, in dollars, of the laundry items is $885.

A total is a whole or complete amount, and "to total" is to add numbers or to destroy something. In math, you total numbers by adding them: the result is the total.

Given that, the owner purchases 6 cases of laundry soap, 8 cases of fabric softener, and 3 cases of bleach for the laundromat.

Each case of laundry soap costs $68.45

So, the cost of 6 cases of laundry soap

= 6×68.45

= $410.7

Each case of fabric softener costs $39.71

So, the cost of 8 cases of fabric softener

= 8×39.71

= $317.68

Each case of bleach costs $52.25

So, the cost of 3 cases of bleach for the laundromat

= 3×52.25

= $156.75

Total =410.7+317.68+156.75

= $885.13

≈ $885

Therefore, the best estimate of the total cast, in dollars, of the laundry items is $885.
