Identify a temperature colder than -7.2f. Write an inequality that relates the temperatures. Describe their positions on a horizontal number line.

Answers

colder then -7.2 F would be -8.5 F

-7.2 > -8.5

anything to the left of -7.2 on the number line will be less then(oe in this case, colder then) -7.2....so -8.5 falls to the left of -7.2

Final answer:

A temperature colder than -7.2°F can be -8°F. The inequality representing this is -8 < -7.2. Drawing this on a number line shows -8 is to the left of -7.2, hence colder.

Explanation:

A temperature that is colder than -7.2°F could be -8°F. The inequality that relates -8°F and -7.2°F is -8 < -7.2, because on a number line, numbers to the left are lesser than those to the right. Therefore, -8°F, being to the left/less than -7.2°F on the horizontal number line, is colder.

The Fahrenheit and Celsius temperature scales don't have absolute lowest temperatures like the Kelvin scale. So, temperatures like -10°F or -20°F (for example) are possible and would be colder than -7.2°F.

Give one real world example where you would use absolute value.

Answers

Distance measurements

One example of absolute value in the real world is subtraction.
For example, you have 17_____ and your friend has 62_____.
if you want to see how many more _____ your friend has, you want to make sure that the answer will be positive. The way that you do this is you subtract |17 - 62| = 45
(I know.... You could just do 62 - 17, but absolute value can be used so you can subtract |a - b| and |b - a|, and they will turn out the same.)

A social worker examines the level of aggression (measured on a 100-point scale) of four groups of individuals before they begin anger management classes. Using the weighted mean, determine the overall mean level of aggression for all four groups.
Group 1 82; 15
Group 2 87; 12
Group 3 93; 22
Group 4 79; 71

Answers

For this solution, we are assuming that the 1st number listed for each group is the mean aggression for that group, and the 2nd number is the number of participants of that group. 1. Find the total number of participants: 15 + 12 + 22 + 71 = 120 participants across all 4 groups 2. Find the total number of aggression points (group mean * group participants): 82(15) + 87(12) + 93(22) + 79(71) = 9929 total aggression points 3. Divide total aggression points by number of participants to find overall mean: 9929/120 = 82.742 or approximately 83.

the backpacking Club is having some posters printed the printer charges $180 plus 250 per poster how many posters can be printed for $1,000 please explain

Answers

Final answer:

To find out how many posters can be printed for $1,000, we need to set up an equation and solve for 'x'. The cost of printing 'x' posters is $180 plus $250 per poster. After solving the equation, we find that 3 posters can be printed for $1,000.

Explanation:

To find out how many posters can be printed for $1,000, we need to set up an equation.

Let's say the number of posters is 'x'. The cost of printing 'x' posters is $180 + $250 * 'x'.

We want to find out when the cost equals $1,000, so we can set up the equation: 180 + 250 * 'x' = 1000.

To solve this equation, subtract 180 from both sides and then divide by 250. This will give us the value of 'x', which represents the number of posters that can be printed for $1,000.

Once you solve the equation, you will find that 'x' is equal to 3.2. However, since you cannot print a partial poster, we can conclude that 3 posters can be printed for $1,000.

Can any three side lengths make a triangle? Explain your reasoning.

Answers

In most cases its possible, but if the 2 of the shortest side lengths are added together and the sum is greater than the 3rd side length, than making a triangle is not possible.

The triangle shown at the right is isosceles that is it has two sides equal length the third side is 30 m shorter than twice the length of each congruent side the perimeter is 570 find the length of each side

Answers

Final Answer:

2(x−15)

Step 1: Translate the problem into a system of equations

We are given that the triangle is isosceles, meaning two sides have the same length. Let's call this length x. The third side is 30 meters shorter than twice the length of each congruent side, so it has a length of 2x−30. The perimeter of the triangle is the sum of all three side lengths, which is equal to 570 meters.

Therefore, we can set up the following equation:

x+x+(2x−30)=570

Step 2: Solve the system of equations

Combining like terms, we get:

4x−30=570

Adding 30 to both sides, we get:

4x=600

Dividing both sides by 4, we get:

x=150

Step 3: Find the side lengths

Now that we know the value of x, we can find the lengths of all three sides:

The first and second sides have a length of x, which is 150 meters each.

The third side has a length of 2x−30, which is 2(150) - 30 = 270 meters.

Answer:

The lengths of the sides of the triangle are:

First side: 150 meters

Second side: 150 meters

Third side: 270 meters

Final Answer:

2(x−15)

The probbale question can be: The triangle shown at the right is isosceles. That is, it has two sides of an equal length. The third side is 30 m shorter than twice the length of each congruent side. The perimeter is 570 m. Find the length of each side.

Alaina sugar cookie recipe calls for 2 1/4 cups of flour per batch if she wants to make 2 /3 a batch of cookies how much flour should she use

Answers

If we have 2+1/4 for a batch and want 2/3rds of that, we multiply (2+1/4) by 1/3 to get 2/3+1/12 (we can just multiply the denominator by 3 to divide by 1/3) = 8/12+1/12=9/12=3/4 ( we get 8/12 by figuring out that 12/3 =4 so we multiply 2/3 by 4/4). Since we need 2/3rds, we then multiply 3/4 by 2 to get 6/3 or 3/2.

Answer:

Alaina will require 1.5 cups of flour to make [tex]\frac{2}{3}[/tex] batches of cookies.

Step-by-step explanation:

We are given the following information in the question:

Amount of flour required per batch of cookies =

[tex]2\displaystyle\frac{1}{4}\text{ cups}[/tex]

Number of batches of cookies Alaina wants to make = [tex]\displaystyle\frac{2}{3}[/tex]

Formula:

[tex]\text{Flour required} = \text{Flour required to make 1 batch of cookies}\times \text{Number of batches}\\\\=2 \displaystyle\frac{1}{4}\times \frac{2}{3}\\\\= \frac{9}{4}\times \frac{2}{3} = \frac{3}{2} = 1.5\text{ cups of flour}[/tex]

Hence, Alaina will require 1.5 cups of flour to make [tex]\frac{2}{3}[/tex] batches of cookies.

Round 12.5829 to the nearest hundredth. Rounded number = ___

Answers

The hundredth's place is the second number after the decimal. In order to round to such place, you look at the number after it. For example, the number in the hundredth's place in 47.9025 is 0. In order to round, you must look at the number after it, in this case 2. Since 2 is less than 5, the 0 will not be rounded up and remain 0. The answer to your particular question is 12.58.

12.5829 rounded to the nearest hundredth is 12.58.

This is because the thousandths place is a number of 4 or less, which means in rounding to the nearest hundredths place, the value of the hundredths place stays the same.
