Answer:
180 points.
Step-by-step explanation:
Given:
A class will have 1 test and 5 homework assignments to complete.
The test is worth 80 points.
Each homework assignment is work 25% of the test.
Question asked:
How many points may be earned during this unit ?
Solution:
By unitary method:
Points may be earned from 1 assignments =
(given)
= ![\frac{25}{100} \times 80 = \frac{2000}{100} = 20](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B100%7D%20%5Ctimes%2080%20%3D%20%5Cfrac%7B2000%7D%7B100%7D%20%20%3D%2020)
Points may be earned from 5 assignments = ![5\times 20 = 100](https://tex.z-dn.net/?f=5%5Ctimes%2020%20%3D%20100)
Points may be earned from 1 test = ![80](https://tex.z-dn.net/?f=80)
Total points may be earned = 100 + 80 = 180
Therefore, 180 points may be earned during this unit.
Answer: 51.9 degrees
Step by step explanation:
Sin(71)/35.6=Sin(x)/21.3
21.3Sin(71)=35.6Sin(x)
21.3Sin(71)/25.6=sin(x)
Sin^-1(21.3Sin(71)/25.6)=x
51.87827502 degrees=x
51.9= angle x
If she gains a card that would be a positive 1, if she sells one that would be negative 1, and if she keeps one than that would be 0.
Answer:
9 cups of lemonade
Step-by-step explanation:
First, calculate the amount of money Pablo earns every week:
$5 + $7 + $18 = $30
Calculate how much money Pablo gets each week by selling lemonade:

Calculate how many cups of lemonade are being sold each week:
18 ÷ 2 = 9
Pablo needs to sell 9 cups of lemonade each week to reach his goal
7.5 gallons per cubic ft
water is flowing out at a rate of 8 cubic ft per minute.....and if 1 cubic ft = 7.5 gallons, then 8 cubic ft = (8 * 7.5) = 60 gallons per minute
the pool holds 300 gallons....and is filling up at a rate of 60 gallons per minute.....300/60 = 5 minutes <===
