A submarine left Diego Garcia traveling east 5 hours before an aircraft carrier. The aircraft carrier traveled in the opposite direction going 10 km/h faster than the submarine for 2 hours after which time the ships were 110 km apart. Find the submarine's speed
Answer:
40km/hStep-by-step explanation:
Let the submarine's speed be x km/h
the time taken by the submarine is given as 5 hours
the aircraft travels 10km/h faster than the submarine= 15km/h
time taken by the aircraft is 2hours
therefore the distance covered by both vehicles can be described using the expression below
we know that distance=velocity*time, so equating the two vehicles distance to 110km we have
5*x+15*2=110
5x+30=110
solving for x we have
5x=110-30
5x=80
divide both sides by 5 we have
x=80/5
x=40km/h
The submarine's speed is 40km/h

At the beginning of the season, Jamie pays full price for a ticket to see the panthers, her favorite basketball team. The panthers currently have 33 wins and 31 losses. Represent the total change in the cost of a ticket given their losses. What is the cost of a ticket for the next game they play
Answer:
The answer is below
Step-by-step explanation:
Given that the price of the ticket at the beginning of the season is $49.64 and the ticket price decrease by $0.41 for every loss
a) The cost of the ticket decreases by $0.41 for every game loss, therefore after 31 losses, the change in cost of ticket is given as:
Change in cost = -$0.41 × number of losses = -$0.41 × 31 = -$12.71
b) The cost of a ticket for the next game given they have 31 losses is:
Cost of ticket = Initial cost of ticket + change in cost = $49.64 - $12.71 = $36.93

Consider these situations. In each situation, is the demand for the good elastic or inelastic?
BLANK As the price of flat-screen televisions decreases, the quantity demanded increases significantly.
BLANK As the price of bread decreases, the quantity demanded changes only slightly.
BLANK As the price of a drug used to treat heart disease increases, the quantity demanded remains unchanged.
Answer:
1 elastic
2 inelastic
2 inelastic
Step-by-step explanation:
edge 2021, hope this helps
Here are the elasticities of demand in the following situations :
The demand for flat-screen is elastic.
The demand for bread is inelastic.
The demand for drug is perfectly inelastic.
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Price elasticity of demand = percentage change in quantity demanded / percentage change in price
Types of elasticity of demand are :
1. Elastic demand : If the absolute value of price elasticity is greater than one, it means demand is elastic. Elastic demand means that quantity demanded is sensitive to price changes.
If demand is elastic and price is decreased, quantity demanded would increase. The increase in quantity demanded would be greater than the decrease in demand and this would lead to an increase in revenue.
2. Inelastic demand : Demand is inelastic if a small change in price has little or no effect on quantity demanded. The absolute value of elasticity would be less than one.
3. Unit elastic demand : Demand is unit elastic if a small change in price has an equal and proportionate effect on quantity demanded.
4. Perfectly elastic demand : when demand is perfectly elastic, demand falls to zero when price increases
5.Perfectly inelastic demand : demand is perfectly inelastic when there is no change in the quantity demanded regardless of changes in price.
The demand for flat-screen is elastic. This is because when the price of the television was decreased, demand increased significantly
The demand for bread is inelastic. This is because the fall in quantity demanded was less than than the decrease in the price of bread
The demand for drug is perfectly inelastic. This is because there is no change in the quantity demanded when the price of the drugs was increased.

(04.01 LC) Which set of ordered pairs represents a function? (1 point) {(0, 1), (1, 2), (2, 3), (3, 3)} {(0, 1), (1, 2), (1, 3), (2, 5)} {(0, 0), (1, 2), (2, 4), (2, 6)} {(0, 0), (0, 1), (2, 0), (2, 4)}
The first set:
" {(0, 1), (1, 2), (2, 3), (3, 3)}"
Represents a function.
Which set of ordered pairs represents a function?
A function is a relationship that maps elements from a set (inputs) into elements from another set (output). Such that each input can be mapped into only one output.
Then, for example, the second set:
{(0, 1), (1, 2), (1, 3), (2, 5)}
Is not a function, because the input x = 1 is being mapped into y = 2 and y = 3.
The only case where the inputs are not repeated is on the first set:
" {(0, 1), (1, 2), (2, 3), (3, 3)}"
Where no input is repeated, so this is a function.

Chris wants to order DVDS over the internet. Each DVD costs $ 15.99 and shipping for the entire order is $ 9.99. How much will Chris spend (s) if he buys x DVDS?
Answer:
There are 3 DVD s that can be bought with under $100.
Step-by-step explanation:
Since we have given that
Cost of DVD = $15.99
Cost of Shipping = $ 9.99
Total cost per DVD would be
$15.99 + $9.99 = $ 25.98
Amount he has to spend no more than $ 100.
So, number of DVDs would be
100 ÷ 25.98 = 3.84
Hence, there are 3 DVD s that can be bought with under $100.

Find the equation of the line that has a slope of -½ and passes through the point (-6,9)
Answer:
y = -1/2x +6
Step-by-step explanation:
We can use the slope intercept form of a line
y = mx+b where m is the slope and b is the y intercept
y = -1/2x +b
Substitute the point into the equation
9 = -1/2 (-6) +b
9 = 3+b
9-3 =b
6 =b
y = -1/2x +6

The fraction is equivalent to 0.023. The decimal 0.23 is equivalent to. C. No. Jill is not correct. The fraction is equivalent to 0.0023. The decimal is 0.23 is equivalent to 23/100. D. No, Jill is not correct. The fraction 23/1,000 is equivalent to 2.3. The decimal 0.23 is equivalent to 23/100. D. No, Jill is not correct. The fraction 23/1,000 is equivalent to 2.3. The decimal 0.23 is equivalent to 23/100.
Answer:
B. No, Jill is not correct, the fraction is equivalent to 0.023.
Step-by-step explanation:
The given fraction is [tex]\frac{23}{1000}[/tex]
Observe that in the denominator there is 1000, which has three zeros after 1.
In changing the given fraction to decimal, there must be 3 significant digits after the decimal.
According to this option (b) is correct.
Moreover, when 23 is divided by 1000, we have
[tex]\frac{23}{1000}=0.023[/tex]
But Jill says that 23/1000 can be written as 0.23, so, Jill is not correct.
Hence option (b) is correct,
