Meal tickets at a large school cafeteria cost $4 for children and $9 for adults. On a certain day,
if 14 times as many children's tickets were bought as adult meal tickets, and the total revenue
from selling all tickets was $2,584, about how many children bought meal tickets?

Answers

Answer:

Let's define:

C = number of children tickets bought

A = number of adult tickets bought.

We know that "On a certain day,  if 14 times as many children's tickets were bought as adult meal tickets"

Then we have:

C = 14*A

And we also know that:

"the total revenue  from selling all tickets was $2,584"

Then:

C*$4 + A*$9 = $2,584

Then we have a system of equations:

C = 14*A

C*$4 + A*$9 = $2,584

The first step to solve these is to isolate one of the variables in one of the equations, and then replacing it in the other equation. We can already see that C is already isolated in the first equation, then we can just replace it in the second one to get:

(14*A)*$4 + A*$9 = $2,584

A*$56 + A*$9 = $2,584

A*$65 = $2,584

A = $2,584/$65 = 39.75

Here we should have a whole number, (So one of the numbers given may be incorrect) This is because we can not have a 0.75 of a ticket sold.

In this case, we know that:

C = A*14

C = 39.75*14 = 546.5

We could round this up to get a whole number; 547

About 547 children tickets were sold.

On a number line, the directed line segment from Q to S has endpoints Q at a -8 and S at 12 Point R partitions the direct line segment from Q to S in a 4:1 ratio Which expression correctly uses the formula (m/m+n)(x2 - x1) + x1 to find the location of point R?

Answers

Answer:

[tex]R =\frac{4}{4+1}(12 +8) -8[/tex]

Step-by-step explanation:

Given

[tex]QS = (-8,12)[/tex]

[tex]Ratio = 4 : 1[/tex]

Required

Determine the expression that correctly uses [tex]\frac{m}{m+n}(x_2 - x_1) + x_1[/tex]

In [tex]QS = (-8,12)[/tex]

[tex](x_1,x_2) = (-8,12)[/tex]

and

[tex]m:n = 4:1[/tex]

Substitute these values in:

[tex]\frac{m}{m+n}(x_2 - x_1) + x_1[/tex]

[tex]R =\frac{4}{4+1}(12 - (-8)) + (-8)[/tex]

The expression becomes:

[tex]R =\frac{4}{4+1}(12 +8) -8[/tex]

Solving further:

[tex]R = \frac{4}{5}(20)-8[/tex]

[tex]R = \frac{4*20}{5}-8[/tex]

[tex]R = \frac{80}{5}-8[/tex]

[tex]R = 16 - 8[/tex]

[tex]R = 8[/tex]

Hence, R is at 8 on the number line

The amount a basketball coach spends at a sporting goods store depends on the number of basketballs the coach buys. The situation is represented by the function rule a= 13b.
Make a table of values and graph the function rule. Is the graph continuous or​ discrete? Explain.
Suppose the coach spent ​$117 before tax. How many basketballs did she​ buy?

Answers

I hope this helps! Have a good day

The graph is discrete and the coach can buy 9 basketballs with $117.

What are Continuous and Discrete Functions?

Continuous functions are those functions for which the value of function can take any number on a certain interval.

Discrete functions, on the other hand, takes separate and distinct values for the function.

The function here is,

a = 13 b

where a is the amount spending on the store and b is the number of basketball she buys.

(a) The table is shown below:

b : 0      1        2       3       4  

a : 0      13     26     39     52

The graph is discrete because the function values are discrete.

(b) If the coach spent $117,

a = 117

b = a / 13

b = 117 / 13

b = 9

Hence the graph of the function is discrete and the coach can buy 9 basketballs with the given amount.

The mayor of a town has proposed a plan for the construction of an adjoining bridge. A political study took a sample of 1300 voters in the town and found that 38% of the residents favored construction. Using the data, a political strategist wants to test the claim that the percentage of residents who favor construction is over 35%. Testing at the 0.05 level, is there enough evidence to support the strategist's claim?

Answers

Answer:

We reject H₀, we have enough evidence to support the claim that the porcentage of residents who favor construction is over 35%

Step-by-step explanation:

Sample size    n  = 1300

Sample  proportion   p = 38 %      =  0,38   then  q = 62%   q =  0,62

The size of the sample is enough to consider the binomial distribution can approximate to normal distribution

p*n  =  1300*0,38     q*n  =  1300*0,62  

p*n > 10    q*n> 10

Population proportion   35%        p₀  = 35 %    p₀  = 0,35

Hypothesis Test :

Null Hypothesis                                         H₀           p = p₀

Alternative Hypothesis                             Ha           p  > p₀

The hypothesis test is a one-tail test to the right

Significance Level   α  =  0,05  we go to z-table and find z(c)

z(c) =  1,64

To calculate  z(s)

z(s)  =  (  p  -  p₀ ) / √ p*q/ n

z(s)  =  0,38  -  0,35  / √ ( 0,38 * 0,62) / 1300

z(s)  =  0,03 / 0,013

z(s)  =  2,307

Comparing  z(c)  and  z(s)

z(s)  >  z(c)      2,307  >  1,64

z(s)  is in the rejection region for H₀, we must reject H₀

We have enough evidence to support the claim

A construction crew is lengthening a road that originally measured 41 miles. The crew is adding one mile to the road each day.
Let L be the length (in miles) after D days of construction.

Write an equation relating L to D. Then use this equation to find the length of the road after 14 days.

Answers

Answer:

41 + (D x 1) = L

Step-by-step explanation:

To determine the necessary equation to lengthen a road whose initial measure is 41 miles, knowing that a new mile is built every day, the following equation must be performed:

41 + (D x 1) = L

Thus, if 14 days had passed, the length of the journey would be determined as follows:

41 + (14 x 1) = L

41 + 14 = L

55 = L

Therefore, after 14 days, the road's length will be 55 miles.

If $120.99 is charged for 654 units of electricity
used, find the cost of one unit of electricity,
plz help me solving this question step by step this is important for me​

Answers

Answer:

The cost of one unit of electricity is $0.185

Step-by-step explanation:

Amount charged = $120.99

Units of electricity used = 654

The cost of a unit of electricity can be determined by dividing the amount charged by the number of units used.

So that,

cost of one unit of electricity = [tex]\frac{120.99}{654}[/tex]

                                    = 0.185

cost of one unit of electricity = $0.185

This implies that the cost of electricity used is charged at $0.185 per unit.

Thus for 654 units of electricity used, the cost would be;

654 x $0.185 = $120.99
