A) 15/25 = 10/p
Answer:
p = 50/3
Step-by-step explanation:
15/25 = 10/p
Using cross products
15*p = 25*10
15p = 250
Divide by 15
15p/15 = 250/15
p = 50/3

If u={a,b,c,d}and p={b,d,e}find p(bar at the top)
Answer:
{a , c}
Step-by-step explanation:
first find u intersection p
n(U n P ) = {a , b , c , d} n {b , d , e}
={d , b}
intersection means element or values which lies in both the sets
now to find p complement
note : p( bar at the top ) is read as p complement
p complement = n(U) - n(U n P)
={a , b , c , d} - {d , b}
={a , c}
n(U) -n(U n P) means the elements which is only in n(U ) but not in n(U n P)
Answer:
a,c

=======================================================
Explanation:
There is a dime and 2 quarters in the bottom row.
So we have 10+25+25 = 60 cents in the bottom row.
Then in the top row, there's a penny and a nickel. So that's an extra 1+5 = 6 cents.
Overall, the total value is 60+6 = 66 cents
Note: 66 cents converts to $0.66 or you can say 0.66 dollars.

It costs $8 to sign up for a music download service and $0.75 to download each song. Jada signs up for the service and begins downloading music.
1. Complete the table showing how Jada can spend money downloading songs.
2. Write an equation relating the number of individual songs, s, Jada downloads and the amount of money, m, Jada spends.
Answer:
1. down below
2. m = 0.75s + 8
Step-by-step explanation:
The equation is m = 0.75s + 8 because Jada needs to pay $8 immediately to sign up, then $0.75 extra for every downloaded song.
This will help us find the missing values in the table.
When s = 4,
m = 0.75 * 4 + 8
= 3 + 8
= 11 ($11.00)
When m = 19.25,
s = (m-8)/0.75
= (19.25-8)/0.75
= 15
When s = 30,
m = 0.75 * 30 + 8
= 22.5 + 8
= 30.5 ($30.50)
Answer:
Equation: Money spent (s) = 0.75m (each music downloaded) + 8 (constant price of membership)
Table (in order) : $11, 15 songs, $30.5
Taivon is training for a running and biking race. The biking part of the race is longer than the running part, so while Taivon trains, he wants to bike more than he runs. He decides that for every 4 miles he runs, he wants to bike 16 miles. How far should Taivon bike if he runs 11 miles?
Answer:
44 miles
Step-by-step explanation:
He bikes 4 miles for every mile he runs so 11 times 4 = 44.

(you'll have to read the explanation)
Step-by-step explanation:
There are 8 lines from 1 to 2, so plotting 1 1/2 (or 1.5) is right in between. I'm not sure how to add the picture back into the explanation, but I will try my best to explain. You want to plot your point for 1 1/2 4 lines after the 1. For the 2 1/4, you want to plot your point on the second line from the 2. Let me know if it doesn't make sense!
Answer: See the attached image below
1 1/2 is located at the exact midpoint between 1 and 2.
2 1/4 is located 2 tickmarks to the right of 2.
===================================================
Explanation:
Think of 1/2 as 4/8
The number 1 1/2 is the same as 1 4/8
So we start at 1 and move 4 tickmarks to the right to get at the exact midpoint (note there are 8 tickmarked spaces between any two whole numbers).
This places us exactly at the midpoint between 1 and 2.
-----------------
To plot 2 1/4, we will effectively plot 2 2/8 since 1/4 = 2/8
We start at 2 and then move 2 tickmarks to the right to arrive at 2 2/8

Answer:
50 more people chose dogs over cats
Step-by-step explanation:
55 divided 100= 0.55 x 200= 110
30 divided 100= 0.3 x 200= 60
To find out how many more people chose dogs over cats:
110-60= 50
I did this because it said "How many more" Which meant the difference.
