Answer:

34 & 34

Step-by-step explanation:

Step-by-step explanation:

1) if total number of the saled tickets is 189, then it is possible to write s+a=189, where s - number of student tickets, a - adult tickets.
2) if the ratio is 4:5, then it is possible to write s:a=4:5;

3) using the two equations it is possible to make up the system:

[tex]\left \{ {{s+a=189} \atop {\frac{s}{a} =\frac{4}{5} }} \right.[/tex]

4) Part A: after solution the system above the number of student tickets = 84; adult tickets = 105.

5) Part B: the revenue from selling the adult tickets is: 105*7=735, the student tickets is: 84*5=420. Then the required difference is: 735-420=$ 315.

The answer of Y I belive its 75 degrees and Z is 105 degrees

Step-by-step explanation:

Because a triangle equals 180 so 180-75 gives you 105 for Z

im positive this is right im not sure correct me if im wrong

The measures of Angles Y, and Z on the map where, all numbered streets run parallel to each other is 75 and 105 degrees respectively.

Angles formed by the transverse line cut by the transversal-

In the given map, all numbered streets run parallel to each other.  Here, both 3rd and 4th streets are intersected by King Avenue.

Here, the delivery driver is driving around town and has noticed that every time he turns, it creates an angle.

The angle y is the angle whose measure is 75 degree are the corresponding angle. Therefore, they must be equal as,

[tex]m\angle y=75^o[/tex]

Hence, the measure of angle y is 75 degrees.

The angle y angle z are the supplementary angle, made on the same line. Therefore,

[tex]m\angle y+m\angle z=180^o\\75+m\angle z=180\\m\angle z=180-75\\m\angle z=105[/tex]

Hence, the measures of Angles Y, and Z on the map where, all numbered streets run parallel to each other are 75 and 105 degrees respectively.

Answer:

40 goodie bags

Step-by-step explanation:

We know that there are 1000 grams in a 1 kilogram. So the weight of the box with the party goody bags is 6200 grams. To get the weight of just the goody bags, we subtract the weight of the empty box from the box with the goody bags. We have 6200-200=6000 grams. So the weight of all the goody bags is 6000 grams. Since each goody bag is 150 grams, we divide 6000 by 150. So, 6000/150 = 40. Therefore there are 40 goodie bags.

Answer:

5 (2.50 + 3.50)

The total cost is $30

$12.50 on soda and $17.50

The total cost of all the items for 5 members is $6.00 when the cost of soda is $2.50 and the cost of hot dog is $3.50.

Given that:

Cost of soda  =  $2.50

Cost of hot dog = $3.50

The total cost of both the items can be calculated by adding the cost of both the items.

Cost of both items = 2.50 +3.50

                              = $6.00

The cost can also be calculated using distributive property as:

Cost of both items = 2.00+3.00+ 0.50 + 0.50

                                 = $6.00

Thus, the cost of both the items is $6.00.

Answer:

Step-by-step explanation:

2/3 * 45 is 30

2/5 * 30 is 12

12+30= 42

45-42=3

I believe this is correct

Answer:

3

Step-by-step explanation:

If 2/3 of 45 were sold then what is left is 1 - 2/3 = 1/3 of 45 or (1/3)*45 = 15 copies.

Then 4/5 of 15 were sold and what is left is 1 - 4/5 = 1/5 of 15 or 3 copies.

Answer:

The radius of a rubber ball, r = 4.5 cm

We need to find the volume of this rubber ball.

The formula for the volume of a sphere is given by :

V=\dfrac{4}{3}\pi r^3V=34πr3

Put r = 4.5 cm in the above formula

\begin{gathered}V=\dfrac{4}{3}\pi \times (4.5)^3\\\\V=381.70\ cm^3\\\\\text{or}\\\\V=382\ cm^3\end{gathered}V=34π×(4.5)3V=381.70 cm3orV=382 cm3

So, the volume of this sphere ball is 382\ cm^3382 cm3 .

The solutions to the equation log (2 x + 1) = 3x-2 are -0.5 and 0.8.

Equation to be solved is:

log (2 x + 1) = 3x-2

The solution to two functions is the corresponding x value where graphs of two functions intersect.

From the attached diagram, we can see that the two graphs intersect at x=-0.5 and x=0.8.

Therefore,the solutions to the equation log (2 x + 1) = 3x-2 are -0.5 and 0.8.
