How many pounds of green tea, worth $40 a pound, should be mixed with herbal tea, worth $50 a pound, to produce 20 pounds of blend worth $42 a pound?
Answer:
840
Step-by-step explanation:
First you have to multiply 42 by 20. Because you have to find the total cost of the whole bag. Then a little guess and check you would get 16 lb of green tea and 4 lb of herbal tea. They both have to equal 20 lbs and $840. Multiply 16 by 40 then 50 by 4 then add them together you will get 840.
Hope this was helpful.

Which of the following represents the equation below in intercept form?
f (x) = 2x² + 6x - 80
A) f (x) = (x-5) (x+8)
B) f (x) = 2 (x-5) (x+8)
C) f (x) =2 (x+5) (x-8)
D) f (x) = 2 (x-4) (x+10)
Answer:
A
Step-by-step explanation:
since your in hurry i wont be showing work
Answer: B
is B f(x) = 2 (x-5) (x+8)
Step-by-step explanation:
Because you simplify
f (x) = 2x² + 6x - 80
f (x) = 2x2+6x−80
f (x) = 2x2+6x−80
= 2 (x−5)(x+8)

The sale price of an item is $330 after a 25% discount. What was the original price of the item?
Answer:
The original price of the item is $440.
Step-by-step explanation:
If you have a discount for 25% and the resulting price is 330, then 330 is 75% of the original price.
Because of the way my brain works, my first thought was that if $330 is 75% of the original price then, 1/3 of 330 would be 25% of the original price. So, I multiplied 330 by 1/3 and got 110. Then I added 110 and 330 to get 440, the original price.

The EX Excavation will charge $980 for 40 cubic yards of dirt.
What is unit rate?A unit rate means a rate for one of something.
Given a graph showing cost for per cubic yard of dirt.
The unit rate = 196/8 = 490/20 = 637/26 = 24.5
Therefore, for 40 cubic yards of dirt = 40*24.5 = 980
Hence, The EX Excavation will charge $980 for 40 cubic yards of dirt.

Kari plans to sample 20 people of a population that contains 100 students. She wants to determine how many people wake up before 6 a.m. Which sample is the most random?
the first 20 students who arrive at school in the morning
all 20 boys on the swim team
5 students out of each of the 4 homeroom classes
the last 20 people in line for breakfast in the cafeteria
Answer:
5 students out of each of the 4 homeroom classes
Step-by-step explanation:
The most random sample is 5 students out of each of the 4 homeroom classes.
Thus, option (C) is correct.
Selecting 5 students from each of the 4 homeroom classes ensures that the sample represents a diverse range of students from different classes.
This approach helps to minimize bias and increase the randomness of the sample.
The other options, such as selecting the first 20 students who arrive at school or the last 20 people in line for breakfast, may introduce some bias based on the specific circumstances or characteristics of those groups. Selecting all 20 boys on the swim team would also not provide a representative sample of the overall student population.
Thus, option (C) is correct.

Find the missing side of each triangle.
Answer:
x = 2√5
Step-by-step explanation:
Using the Pythagorean Theorem:
a² + b² = c²
You can identify that x is the hypotenuse, as it is opposite to the right angle.
So:
3² + √11² = x²
9 + [(√11) (√11)] = x²
9 + 11 = x²
20 = x²
√20 = √x²
√4√5 = x
2√5 = x
x = 2√5

DOGS During a recent visit to the veterinarian's office, Mrs. Cho was informed that a healthy weight for her cat is approximately 35 pounds, plus or minus three pounds. Write an absolute value inequality that represents healthy weights w for her dog.
Answer:
Step-by-step explanation:
from the given information:
The healthy weight of the cat = 35 pounds
with +/- 3
To write the absolute value;
The healthy weight will either be less or greater.
So; w > 35 +3 or w < 35 - 3
w - 35 > 3 or w - 35 < -3
Thus, the healthy weight will be |w - 35| > 3
