i need help with a math problem right now it says A car rental agency advertised renting a car for $24.95 per day and $0.26 per

Dominik [7]

Answer:

He can drive 481 miles if David rents his car for three days

Step-by-step explanation:

This is true because if you take the 24.95 and multiply it by 3, because he rented it for three days, you'll get 74.85. Then you'll subtract 200 (the total money that can be spent) by 74.85 you'll get 125.15. Divide the remaining number, 125.15 by 0.26 to get 481.34. Take the decimals away because you don't need it, if you want to be sure it's correct you can multiply 481 by 0.26 to get 125.05 which is lower than 125.15 so it good because if you use 482 besides 481 it will be higher than the amount of money David can spend, that's why 481 is the right answer.

Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one sam

kogti [31]

Answer:

Advance tickets-$15

Same-day tickets-$20

Step-by-step explanation:

let x be the cost of advance tickets and y cost of same-day tickets:

$x+y=35\ \ \ \ \ \ \ ...i$

Given that there were 40 advance and 25 same-day tickets for a total of $1100:

$40x+25y=1100\\\\8x+5y=220\ \ \ \ \ \ \ \ \ \ \ ...ii$

#Make x the subject in i and substitute in ii:

$x=35-y\\\\\therefore 8x+5y=220, x=35-y\\\\8(35-y)+5y=220\\\\280-8y+5y=220\\\\60=3y\\\\y=20\\\\x=35-y=35-20=15$

Hence, advance tickets cost $15 each while same-day tickets cost $20 each.

Can someone solve this question?

Rom4ik [11]

The triangles are isosceles. The following notation are for the angles. For example ABD is refer to the angle located in the B vertex, formed by the segments AB and BD.

$ABD = ADB\\40 + 2ADB = 180\\ADB = 70 = ABD\\$

$70 + DBC + 30 = 180\\DBC = 180 - 100 = 80$

Then

$BCD = BCD\\2BCD + 80 = 180\\BCD = 50$

You pick a card at random. Without putting the first card back, you

Inga [223]

First, we need the probability of picking an odd number.

There are 5 cards in total, and 3 odd cards (3, 5, and 7).

That means that the probability that we'll draw an odd card would be $\frac{3}{5}$ .

Then, we have 4 cards left, and 2 even cards (4 and 6), meaning that the probability that we draw an even card will be $\frac{2}{4}$ or $\frac{1}{2}$ .

To find the probability that these would happen in consecutive draws, we just multiply the probabilities together.

$\frac{3}{5}*\frac{1}{2}=\frac{3}{10}$ or 0.3.

To convert this into a percentage, we multiply the decimal by 100.

$0.3*100=30$ .

So the probability of picking an odd number and then picking an even number is 30%.

Hope this helps!
