tickets to a concert went on sale at 10 a.m. by 12 p.m. 208 tickets have already been sold at this rate how many tickets will be sold in the first 5 hours of the tickets go on sale
A. 520
B. 1,040
C. 41.6
D.728
Answer:
We conclude that 520 tickets will be sold in the first 5 hours of the tickets go on sale.
Hence, option A is true.
Step-by-step explanation:
Given that the tickets to a concert went on sale at 10 a.m. by 12 p.m.
10 a.m. by 12 p.m means the total number of hours = 2 hoursGiven that the tickets sold in 2 hours = 208
Thus,
Unit rate = 208 tickets / 2 hours
= 104 tickets per hour
Therefore,
Tickets sold in the first 5 hours of the tickets go on sale:
104 × 5 = 520 tickets
Therefore, we conclude that 520 tickets will be sold in the first 5 hours of the tickets go on sale.
Hence, option A is true.

Answer:
[tex]\dfrac{31}{2}+\dfrac{27}{2}i[/tex]
Step-by-step explanation:
The given complex number is:
[tex]z=\dfrac{(2+3i)(4-7i)(1+i)}{(1^2-i^2)}[/tex]
Firstly we can solve (2+3i)(4-7i)(1+i)
= 2(8)+2(-7i)+4(3i)+3i(-7i²)× (1+i)
= (16-14i+12i-21i²i)× (1+i)
Since, i² = -1
= (16-14i+12i-21(-1)i)× (1+i)
= (16-14i+12i+21)× (1+i)
= (29-2i)(1+i)
= 31+27i
Denominator : (1-i²)
= (1-(-1))
= 2
[tex]\dfrac{(2+3i)(4-7i)(1+i)}{(1^2-i^2)}=\dfrac{31+27i}{2}\\\\=\dfrac{31}{2}+\dfrac{27}{2}i[/tex]
Hence, the correct answer is [tex]\dfrac{31}{2}+\dfrac{27}{2}i[/tex].

Shaq runs once around the track in 8.07 minutes. Felicia runs once
around the track in 4.90 minutes less than Shaq. How long does it
take Felicia to run once around the track? HUH?! Please help!
Answer:
Felicia needs 3.17 minutes to run once around the track
Step-by-step explanation:
Subtraction
Shaq is known to run once around the track in 8.07 minutes. Felicia runs once around the track in 4.90 less than Shaq.
We don't know how long does it take Felicia to run once around the track, but we can find it by subtracting the time done by Shaq with the difference between their relative times.
Felicia takes 8.07 min - 4.90 min = 3.17 min.
Felicia needs 3.17 minutes to run once around the track
Can someone help I think it’s a, b, d but I would like to see what everyone else’s opinion is:)
Answer:
D
Step-by-step explanation:
There are 5 ways to prove congruence:
1. SSS (3 sides)
Not applicable here
2. SAS (side-angle-side)
This requires a side, then an angle in between, and another side. This cannot be met with angles (as we currently have side-angle) so none of these are possible
3. ASA (angle-side-angle)
This is a side between angles, so if we squished line AC between angles C and A, and angle A=angle O, this would be true -- B is one answer
4. AAS (angle-angle-side)
Similar to option 3, but would be with angles T and G instead,
D is another answer
5. hypotenuse leg (only in right triangles)
The reason T and G fit AAS is because we hit angle T, then angle C, then side CA, all congruent with G, D, and DO in that order.
In the notation "s(X) = ...," what does "s(x)" represent?
A.
The value of s(x) depends on the value of x, since s is a function of x.
B.
The value found when sis multiplied by the value x.
С.
There is not enough information to answer this question.
D.
The value of x depends on the value of s(x), since x is a function of s.
Answer: Choice A) The value of s(x) depends on the value of x, since s is a function of x.
The outer letter s tells us what the function's name is. It's the dependent variable and it might be handy to tie it to the y variable. The x is the independent variable. It changes freely without relying on what s happens to be.
Answer: A. The value of s(x) depends on the value of x, since s is a function of x.
Step-by-step explanation: s(x) is the output of the function when a given value of x is calculated according the operations in the function.
Maria planted 6 pots of flowers each pot holds 8 flowers. Explain how to use the bar model to solve for the total number of flowers. Include the total number of flowers in your answer
Answer:
[tex]48[/tex]
Step-by-step explanation:
There are [tex]6[/tex] pots each of which contains [tex]8[/tex] flowers.
In the bar model it can be seen that one unit of the bar represents a pot with [tex]8[/tex] flowers. The entire bar represents [tex]6[/tex] pots. We will need to add [tex]8[/tex] six times or multiply [tex]8[/tex] with [tex]6[/tex] to find the total number of flowers.
So total number of flowers is
[tex]8+8+8+8+8+8=48[/tex]
or
[tex]8\times 6=48[/tex].
So, the total number of flower is [tex]48[/tex].

In the figure below, k || l and m || n. Find the values of x and y.
Answer:
y=36
Step-by-step explanation:
using that 63° angle there on the right, we know that the other angle for a 180° total is 117°.
Now we have to figure out y using that total of 117
(4y-27)=117
4y-27=117
4y=144
y=36
Now if we substitute y...
(4y-27)=117
(4(36)-27)=117
(144-27)=117
(117)=117

Colton is taking a long bike ride where he rides at a constant speed. The distance he bikes is proportional to the amount of time he has been biking. After 3.5 hours, he has traveled a distance of 49 miles.(b) Colton travels at the same rate as in (a) for 6 hours. Let d be the distance he biked. Set up and solve a proportion for d. (c) Colton would like to bike 200 miles. Let h be the number of hours it will take Colton to bike this distance. Solve a proportion for h. Round to the nearest tenth of an hour.
Answer:
b) [tex]d[/tex] = 84 miles
c) [tex]h[/tex] = 14.3 hours
Step-by-step explanation:
Given that:
The speed of Colton is constant while riding a bike.
Formula for speed is given as:
[tex]Speed = \dfrac{Distance}{Time}[/tex]
If speed is constant, then we can deduct that:
[tex]Distance \propto Time[/tex]
Time = 3.5 hours
Distance = 49 miles
Therefore, the speed will be equal to:
Speed = [tex]\frac{49}{3.5}[/tex] = 14 miles/hr
b) Given that:
Time = 6 hours, then we have to find the distance to be hiked if the speed is same.
[tex]14 = \dfrac{d}{6}\\\Rightarrow d = \bold{84}\ miles/hr[/tex]
c) Given that:
Distance = 200 miles
Number of hours = [tex]h[/tex]
To find, the value of [tex]h[/tex].
[tex]14 = \dfrac{200}{h}\\\Rightarrow h = \dfrac{200}{14}\\\Rightarrow h = \bold{14.3}\ hours[/tex]

Write the word sentence as an inequality. Then solve the inequality.
Six times a number x is at least −24.
An inequality is
.
The solution of this inequality is
.
Answer:
The inequality is 6x ≥ -24
The solution of this inequality is {x : x ∈ R, x ≥ -4} ⇒ [-4, ∞)
Step-by-step explanation:
In the inequality not more than means ≤In the inequality at least means ≥Let us solve the question
∵ Six times a number x means 6 × x = 6x
∵ At least means ≥
∴ Six times a number x is at least -24 is 6x ≥ -24
∴ The inequality is 6x ≥ -24
Now we will find the solution of the inequality
∵ 6x ≥ -24
→ Divide both sides by 6
∵ [tex]\frac{6x}{6}[/tex] ≥ [tex]\frac{-24}{6}[/tex]
∴ x ≥ -4
∴ The solution of this inequality is {x : x ∈ R, x ≥ -4} ⇒ [-4, ∞)
Answer:
The inequality is 6x ≥ -24
The solution is x ≥ -4
Step-by-step explanation:
To solve this you have to divide both sides by 6, so 6 ÷ 6 cancels out and -24 ÷ 6 = -4
So, the solution is x ≥ -4
Jodie spent 25% less buying her English reading books thank Claudia. .Gianna spent 9% less than Claudia. Gianna spent more than Jodie by what percent? If your using decimal round to the nearest tenth
Answer:
21.3%
Step-by-step explanation:
Given that:
Money spent by Jodie for buying English reading books = 25% lesser than that of Claudia
and
Money spent by Gianna is 9% lesser than that of Claudia.
To find:
By what percent, Gianna spent more than Jodie ?
Solution:
Let the money spent by Claudia on her English books = 100
Now, as per question statement:
Money spent by Jodie = 100 - [tex]\frac{9}{100}\times 100[/tex] = 75
Money spent by Gianna = 100 - [tex]\frac{25}{100}\times 100[/tex] = 91
Now, to find the answer:
[tex]\dfrac{\text{Difference between money spent by Gianna and Jodie}}{\text{Money spent by Jodie}}\times 100[/tex]
[tex]\Rightarrow \dfrac{91-75}{75}\times 100\\\Rightarrow \dfrac{16}{75}\times 100\\\Rightarrow \bold{21.3\%}[/tex]
Therefore, Gianna spent 21.3% more than the amount that was spent by Jodie.

how is per capita gross domestic product calculated "total market value of goods and services produced within a year divided by total population"?
Answer: See explanation
Step-by-step explanation:
You didn't really say what you want to know but let me explain.
The gross domestic product of an economy is the value of the goods and.d services that are being produced in such an economy. The gross domestic Product is used to know how well an economy is doing
Per capita gross domestic product (GDP) is a used to know the economic output of a particular country per person. It is calculated by dividing the GDP of such an economy by the population.
For example, let us say the GDP of a country is $800,000,000 and the population is 3,500,254. Therefore, the per capita GDP would be:
= $800,000,000 / 3,500,254
= $228.56 per person

Alan bought 3 CDs that were each the same price. Including sales tax, he paid a total of $38.70. Each CD had a tax of $1.10. What was the price of each CD before tax?
Answer:
$11.80
Step-by-step explanation:
3*$1.10 = $3.30
price without tax,
= 38.70-3.30
= 35.40
Cost of each CD,
= 35.40/3
= 11.80
Answer:
11.80 dollars
Step-by-step explanation:
Well, first I would multiply 1.10 by 3 which is 3.30 then subtract 38.70 - 3.30 and get 35.40, and finally divide 35.40 by 3 to get 11.80
