4 liters of 2% milk contains 8% cholesterol. A container of skim milk contains 2% cholesterol. How many liters of skim milk need to be added to the 4 liters of 2% milk to create a mixture with 4% cholesterol?
Answers
To solve this problem, we can set up an equation based on the amount of cholesterol in the mixture.
Let's assume that x liters of skim milk need to be added to the 4 liters of 2% milk.
The amount of cholesterol in the 4 liters of 2% milk is 8% of 4 liters, which can be calculated as (8/100) * 4 = 0.32 liters of cholesterol.
The amount of cholesterol in the x liters of skim milk is 2% of x liters, which can be calculated as (2/100) * x = 0.02x liters of cholesterol.
The total amount of cholesterol in the mixture is the sum of the cholesterol in the 2% milk and the skim milk, which should be equal to 4% of the total volume of the mixture. So, we have:
0.32 + 0.02x = (4/100) * (4 + x)
Simplifying the equation:
0.32 + 0.02x = 0.04(4 + x)
0.32 + 0.02x = 0.16 + 0.04x
0.02x - 0.04x = 0.16 - 0.32
-0.02x = -0.16
Dividing both sides by -0.02:
x = (-0.16) / (-0.02)
x = 8
Therefore, 8 liters of skim milk need to be added to the 4 liters of 2% milk to create a mixture with 4% cholesterol.
To solve this problem, we can use the following equation:
4+x4×8+x×2=4
This equation represents the ratio of the total cholesterol to the total volume of the mixture. The numerator is the sum of the cholesterol from the 2% milk and the skim milk, and the denominator is the sum of the volumes of the 2% milk and the skim milk. The equation is equal to 4 because we want the mixture to have 4% cholesterol.
To find x, we can simplify and solve for x:
4+x32+2x=4
32+2x=16+4x
16=2x
x=8
Therefore, we need to add 8 liters of skim milk to the 4 liters of 2% milk to create a mixture with 4% cholesterol.

Use 3.14 for "pi" and round to the nearest hundredths place
Answers
Answer:
36.85 ft
Step-by-step explanation:
3 feet on either end + 6 feet on either side + circumference of the circle
3 + 3 + 6 + 6 + circumference of the circle
18 + circumference of the circle
You can find the circle's diameter by subtracting 6 from 12. You get 6. You can find the radius by dividing the diameter by 2. You get 3.
The formula for circumference is 2·π·Radius
2 · π · 3 = 6 · π = 6 · 3.14 ≈ 36.85

The 16 cases will fit the box as shown.
Step-by-step explanation:
One disk case has the dimensions 14.2 cm by 19.3 cm, with thickness 1.6 cm.
Temporarily ignoring the 14.2 cm and 19.3 cm measurements, we multiply this 1.6 cm thickness by 16, obtaining a total thickness for the stack of cases of 25.6 cm.
1) The 16 cases, arranged as shown, and measuring 25.6 cm from left to right in this diagram, will fit within the 26 cm horizontal distance shown.
2) The horizontal length of each case is 14.2 cm. Stacked as shown, the 16 cases will fit within the 15 cm depth of the box.
3) The vertical measurement of each case is 19.3 cm. The 20 cm vertical measurement of the box can accommodate this 19.3 height within 20 cm.
All indications are that the 16 cases will fit comfortably inside the box.

Answers
Answer: The correct answer is:
Probability of rolling a number less than 3: 2/6 or 1/3
Step-by-step explanation:
Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.
Probability of not rolling a number less than 3: 4/6 or 2/3.
Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

A roll of ribbon was 12 meters long. Diego cut 9 pieces of ribbon that were 0.4 meters each to tie some presents. He then used the remaining ribbon to make some wreaths. Each wreath required 0.6 meter.
How many meters of ribbon were available for making wreaths?
_____ meters
How many wreaths could Diego make with the available ribbon?
_______wreaths
Answers
Answer: 8.4; 14.
Step-by-step explanation:
To find how much ribbon we used to tie presents, we need to multiply 9 and 0.4.
9 x 0.4 = 3.6.
Diego used 3.6 meters of yard to tie some presents. We can subtract that from 12 to find how much ribbon we have left.
12 - 3.6 = 8.4.
We have 8.4 meters of ribbon to make wreaths.
Now we have to find how many wreaths we can make wiht 8.4 meters of ribbon. We know that each wreath needs 0.6, so we should divide 8.4 by 0.6 to find how many wreaths we can make.
8.4 ÷ 0.6 = 14.
Therefore, we can make 14 wreaths with the 8.4 meters of leftover ribbon.
(Part A's answer is 8.4, and Part B's answer is 14)
We start off with 12m
Since there are 9 ribbons each 0.4 meters you have to do 9 • 0.4. Since that is 3.6m.
To find out how much ribbon you have left you must subtract the amount he used against the amount he had to begin with.
12 - 3.6 = 8.4
To find out how many wreaths he can make, you must divide the remaining amount of ribbon he has by the 0.6 meter.
8.4 divided by 0.6 is 14.
Answer:
He can make 14 wreaths with the remaining amount of ribbon.

find the values of x and y
Answers
Answer:
x = 85 Degrees
y = 85 Degrees
Step-by-step explanation:
20 Degrees + 90 Degrees -->
90 and 20 are given => 110 Degrees
e triangle angles sum = 180 Degrees
180 - 110 = 70 Degrees
=> Vertical angles so 25 + x + 70 = 180
x = 85
x + (z) = 180 e sum of half 360
85 + z = 180
z = 95 Degrees
--> z + (y) = 180 e same as above (sum of interior angles)
95 + y = 180
y = 85

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

Get common denominators to determine. Multiply the second one by 2/2

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
