Answer:
80%
Step-by-step explanation:
Given:
Team D used a recipe that consists of 20 cups of sand, 2 cups of flour, and 3 cups of water.
Question asked:
How does the percent of sand in Team D's recipe compare to that of the other teams ?
Solution:
Team D used a recipe that consists of sand = 20 cups
Team D used a recipe that consists of flour = 2 cups
Team D used a recipe that consists of water = 3 cups
Total number of cups together = 20 + 2+ 3 =25 cups
Now we will have to find percent of cups of sand out of the total number of cups.
By using formula of percentage,
Percent = 

Therefore, 80% of sand in Team D's recipe compare to that of the other teams.
7/8
3/4
I'm order for them to have the same denominator you need to multiply so:
¾×2=6/8
So she drank 6/8 pints of water
The number of pages the student can read in a minute is an illustration of rates.
The time left to complete the whole book is 90 minutes
From the complete question, the student's rate is:

The number of pages is:

First, we calculate the time to read the whole book



The number of the student has read is:

Next, we calculate the time spent on the 25 pages



Convert to minutes

So, the time left is:

This gives


Convert to minutes

Hence, the time left is 90 minutes

Perpendicular line : m × m1 = -1
from y =2x-3 , m=2
m1•2 = -1
m1 = -1/2
substitute P in --> y= mx +c
5 = -1/2 (-6) + c
5-3 = c
c = 2
y = -1/2x - 1
