You need a 45% alcohol solution. On hand, you have a 105 mL of a 40% alcohol mixture. You also have 80%
alcohol mixture. How much of the 80% mixture will you need to add to obtain the desired solution?
You will need
mL of the 80% solution
Submit Question
You have 105 mL of a 40% alcohol solution, which contains 0.4 • 105 mL = 42 mL of alcohol.
If you mix it with x mL of 80% solution, you end up with a (105 + x) mL solution that contains (42 + 0.8x) mL of alcohol.
In this solution, you want to have a concentration of 45%, so
((42 + 0.8x) mL) / ((105 + x) mL) = 0.45
Solve for x :
(42 + 0.8x) / (105 + x) = 0.45
(42 + 0.8x) / 0.45 = 105 + x
280/3 + 16/9 x = 105 + x
7/9 x = 35/3
x = 15
So you need 15 mL of the 80% solution.

The perimeter of quadrilateral ABCD is 85. Find the value of x.
The perimeter of ABCD can be calculated using the following formula: Line AB + Line BC + Line CD + Line DA = Perimeter ABCD.
What is meant by Quadrilateral?A quadrilateral is a four-sided polygon with four angles and four vertices. The term "quadrilateral" comes from the Latin words "quadri," which means "four," and "latus," which means "side." A quadrilateral is depicted in the image above. The outcome of an image The perimeter of the quadrilateral ABCD is 85 feet. Find out what the value of x is.The perimeter of a quadrilateral is the entire length of its boundary. Perimeter = AB + BC + CD + DA, for example, can be used to define the perimeter of the quadrilateral ABCD.The perimeter is 85. (the total of all sides). X = 5.5, and 4x + 3x + 4 + 5x-7 + 6x-11 = 85 (18x - 14 = 85). 18 x = 85 + 14 = 99.Therefore,
The perimeter of ABCD can be calculated using the following formula: Line AB + Line BC + Line CD + Line DA = Perimeter ABCD.
When we substitute the provided values, we get: ABCD perimeter = 9 units plus 5 units plus 9 units plus 5 units plus 5 units plus 5 units plus 5 units plus 5 units plus 5 units plus 5 units plus 5 units plus 5 units plus 5 units plus 5 units As a result, the perimeter of ABCD is 28 units.

A glacier in Alaska moves about 29.3 meters a day. About how much farther will it move in 1000 days then it will move in 100 days?
A glacier will move about ______ meters farther in 1000 days then it will move in 100 days.
Fill in the blank
Your answer has to be in decimal form.
BIG THANKS!
Answer:
If it moves 29.3 meters a day, then we need to find the total amount of days:
1000 days + 100 days = 1100 days
Since it moves 29.3m per day, we can write:
29.3m x 1100 which equals 32230m
So it moved 32230 meters

10. While catching fireflies, you and a friend decide to have a competition. After m minutes, you have (4m +11) fireflies and your friend has (5m +6) fireflies
A. Write an expression in simplest form that represents the number of fireflies you and your friend caught together.
B. The competition ends after 5 minutes(m). Who has more fireflies. Explain how you know.
Answer:
Lets look at the expressions with respect to the competition parameters:
Expressions:
You(Y) =4m+11
Friend(F)=5m+6
1. The competition begins AFTER you and friend already caught some flies. This would be represented by the CONSTANT terms in each expression (in this case, 13 for you, 6 for friend).
So the number of flies caught BEFORE THE COMPETITION would be...
11+6=17 flies total
2. The competition length was "m" minutes long when flies are caught and counted. This would be represented by the VARIABLE terms in each expression (in this case, 4m for you, 5m for friend). We are not given a numeric value for the variable "m" to evaluate.
So the number of flies caught DURING THE COMPETITION (timed "m" minutes long) would be....
4m+5m=9m flies total
...and the number of flies per minute would be calculated as......
9m÷m=9 flies per min....total #flies divided by total minutes
3. If the problem asked for the total number of flies caught by you and friend, before and after the competition....
9m+17 flies total.....add like terms in each expression.
Answer:
a. 9m+17
b. You caught more fireflies
