2. Lawn tickets cost $30 each and seat tickets cost $50
each. The organizers want to make at least $14,000
from ticket sales.
If you know that exactly 200 seat tickets were sold,
what can you say about the number of lawn tickets?
In order to complete the target the person must have to sell 133 lawn tickets and 200 seat tickets.
What are arithmetic operations?The study of numbers and their operations, which are essential to all other branches of mathematics, falls under the umbrella of arithmetic operations. The four fundamental operations in these systems are addition, subtraction, multiplication, and division.
It is given that, tickets for the lawn cost $30 apiece, while those for seats cost $50 each. At least $14,000 is what the organizers want to make from ticket sales.
The amount earned from seat tickets,
=$50 × 200
=10000
The amount needed to complete the target,
=$14,000 - $10,000
=$4,000
If they earned $4,000 by selling lawn tickets. Since lawn tickets were $30, the formula to determine how many were sold is $4000 divided by $30.The number of lawn tickets is obtained as,
=4000/30
=133
Thus, the number of lawn tickets will be 200.

-6a+12=42. How do we do this equation
Answer: -5
Step-by-step explanation:
You have to find a. Here's some steps you can take.
1.) Subtract 12 on the left side of the equal sign to get -6a by itself. When subtracting 12 you must subtract 12 from 42 as well.
2.) Your new equation would be -6a = 30
3.) Now you need to get a by itself. How do we do that? By dividing -6a by -6. REMEMBER: You must also do the same to the right side of the equal sign which is 30 (30/-6)
4.) Your problem should end up looking like this: a = -5

it was observed that 60% read

A and 10% all the threes. In the fitness of the thing, state (i) what percentage read exactly
two magazines ? (ii) what percentage do not read any of the threes ?
Answer:
je
Step-by-step explanation:
suis suis pasforet en anglais
We're dealing with percentage. hence, our universal set: U=100%.
Let:A = set of those that read magazine A
B = set of those that read magazine B
C = set of those that read magazine C
(i) we are looking for n{(A n B) u (B n C)}
so, n{(A n B) u (B n C)} = n(A n B) + n(B n C) -n(A n B n C)
n{(A n B) u (B n C)} = 20% + 30% - 10%
: n{(A n B) u (B n C)} = 40%
(ii) We're looking for {A' n B' n C'}
{A' n B' n C'} = n(U) - n(A u B u C)
{A' n B' n C'} = 100% - n(A u B u C)
n(A u B u C) = n(A) + n(B) + n(C) - n{(A n B) - n(A n C) -n(B n C) + n(A n B n C)
n(A u B u C) = 60% + 50% + 50% -30% - 30% - 20% + 10%
n(A u B u C) = 90%
however, {A' n B' n C'} = 100% - n(A u B u C)
: {A' n B' n C'} = 100% - 90%
{A' n B' n C'} = 10%

Calculate the probability of randomly selecting a vehicle with an engine between than 3.1 L and 4.2 L.
Using the normal distribution, it is found that there is a 0.7452 = 74.52% probability of randomly selecting a vehicle with an engine between than 3.1 L and 4.2 L.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.Researching the problem on the internet, it is found that:
The mean is [tex]\mu = 3.59804[/tex].The standard deviation is [tex]\sigma = 0.47986[/tex].The probability is the p-value of Z when X = 4.2 subtracted by the p-value of Z when X = 3.1, hence:
X = 4.2
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{4.2 - 3.59804}{0.47986}[/tex]
[tex]Z = 1.25[/tex]
[tex]Z = 1.25[/tex] has a p-value of 0.8944.
X = 3.1
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{3.1 - 3.59804}{0.47986}[/tex]
[tex]Z = -1.04[/tex]
[tex]Z = -1.04[/tex] has a p-value of 0.1492.
0.8944 - 0.1492 = 0.7452.
0.7452 = 74.52% probability of randomly selecting a vehicle with an engine between than 3.1 L and 4.2 L.

The trapezoids below are similar. Find z.
Answer:
[tex]z = 24.5[/tex]
solving similarities:
[tex]\frac{upper-length}{bottom- length}=\frac{upper-length}{bottom- length}[/tex]steps:
[tex]\frac{2}{14} =\frac{7/2}{z}[/tex]
[tex]2z = \frac{14*7}{2}[/tex]
[tex]2z = 49[/tex]
[tex]z = 24.5[/tex]
Answer:
[tex]z = \dfrac{49}{2}[/tex]
Step-by-step explanation:
If the trapezoids are similar, then the ratio of side lengths will be equal.
[tex]\implies 14 : 2 = z : \dfrac72[/tex]
[tex]\implies \dfrac{14}{2}=\dfrac{z}{\frac72}[/tex]
[tex]\implies z=\dfrac{14}{2} \times \dfrac72[/tex]
[tex]\implies z = \dfrac{49}{2}[/tex]

The speed of the commercial jet is 180 miles per hour faster than the speed of the private airplane. Find the speed, in miles per hour, of both airplanes.
commercial jet
X mph
private airplane
X mph
Answer:
commercial: 540 mphprivate: 360 mphStep-by-step explanation:
Time is inversely proportional to speed for the same distance covered. The ratio of commercial to private speeds is ...
2.4 : 1.6 = 3 : 2
If p is the speed of the private plane, then 3/2p is the speed of the commercial plane and the difference of speeds is ...
3/2p -p = 180
1/2p = 180 . . . collect terms
p = 360 . . . . . . speed of the private plane
3/2p = 540 . . . . speed of the commercial plane
The commercial jet flies 540 mph; the private plane flies 360 mph.
