Answer:
60 kilograms of the 30% solution
140 kilograms of the 40% solution
Step-by-step explanation:
Let x = the no. of kilos containing 30% salt (solution 1)
and 200 - x = the no. of kilos containging 40% salt solution 2)
.30x = amount of salt in solution 1
.40(200 - x) = amount of salt in solution 2
.37(200) = amount of salt in the final mixture
salt in solution 1 + salt in solution 2 = salt in final mix.
.30x + .40(200 - x) = .37(200)
Let's multiply thru the equation by 100 to remove the decimal fractions
30x + 40(200 - x) = 37(200)
30x + 8000 - 40x = 7400
-10x = -600
x = 60 kilograms of the 30% solution
200 - 60 = 140 kilograms of the 40% solution

Answer:
[tex]\sqrt{8x^{2} }[/tex]+5-3 = 8.12
8.12 rounded to nears whole number is 8
therefore 8.12 rounded down to three decimal places is 8.1
Therefore your answer would be 8.1
If it wont let you add a decimal your answer would also be 8
Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 6 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?
Answer:
2/3
Step-by-step explanation:
Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 6 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?
1 decametre = 10 metres
Hence,
10 meters = 6 pieces of ribbon
1 meter = x pieces
Cross Multiply
10x = 6
x = 6/10
x = 2/3 (1 meter pieces of ribbon)

In a biology lab, 500 bacteria reproduce by splitting. Every hour, on the hour, each bacterium splits into two bacteria.
Answer:hour 1 500, hour 2 1000, hour 3 2000 , hour 4 4000
Step-by-step explanation:
After 1 hour 500 bacteria split into 500 bacteria.
After 2 hour 500 bacteria split into 1000 bacteria.
After 3 hour 500 bacteria split into 1500 bacteria.
After 4 hour 500 bacteria split into 2000 bacteria.
Given that,
In a biology lab, 500 bacteria reproduce by splitting.
Every hour, on the hour, each bacterium splits into two bacteria.
We have to find,
Find the number of bacteria after 4 hours.
According to the question,
Let us assume n = the number of bacteria at a given hour.
Total number of bacteria = 500
At the end of 1 hour each of the 500 bacteria after an hour is split in to 2 bacteria. So, at the end of 1 hour = n(1) = 1 × 500 = 500 After 1 hour 500 bacteria split into 500 bacteria.At the end of the 2 hour, each of the 500 bacteria will split in to 2 more bacteria. So, n(2) = 2 x 500 = 1000 bacteria After 2 hour 500 bacteria split into 1000 bacteria.At the end of the 3 hour, each of the 500 bacteria will split in to 2 more bacteria. So, n(3) = 500 x 3 = 1500 bacteria After 3 hour 500 bacteria split into 1500 bacteria.At the end of 4 hours, each of the 500 bacteria spilt into 2 more bacteria.
So, n(4) = 4 × 500 = 2000 bacteria
After 4 hour 500 bacteria split into 2000 bacteria.

How does a quadratic function relate to volleyball and what aspects of quadratic functions are there?
Answer:
Volleyball players want to keep their serves as close to the net as possible, so the ball travels for a shorter period of time. Say a volleyball player serves the ball across the court. If we can model this situation with the function y=-0.006(x−21)2+9, where x is the distance from the player and y is the height, then we can determine if the ball clears the net and lands in bounds 61 feet away1. It may be helpful to analyze this situation graphically, and we consider how to do that in this section.

Complete Question
Mis. Jackson wants to rent a van for a week it will cost a weekly fee plus 0.20 per mile driven let m equal the number of miles Ms. Jackson drives during the week write an algebraic expression that shows a week rent Jackson will pay for the van for the week
Answer:
A = w + 0.20m
Step-by-step explanation:
Step 1
We find the equation for the total amount spent in a week
The total amount to rent the van in a week = A
Weekly fee = w
Number of miles = m
Therefore, thw algebraic expression that shows a week rent Jackson will pay for the van for the week is
A = w + 0.20m

Jenna bought enough lattes for all her friends. Each latte was $3.50
and she gave the barista a $20 bill, who then gave her back $2.50
in change. Write an equation modeling this, with x as the cost per late
How many lattes did she buy?
Answer: 5 lattes
Step-by-step explanation: Our equation is 20 − 3.5x = 2.5, which means x = 5 lattes.
Answer:
Step-by-step explanation:
y=3.5x (cost function where y is cost and x is the number of lattes)
20-2.5=3.5x
17.5=3.5x
5=x
So she bought 5 lattes.
