For adding negatives, you basically just subtract. For example, -3+5. To find the answer, you subtract 3 from 5, leaving you with 2. For decimals, you add like normal, but you carry the decimal down, and leave it in the same place.

Answer:

69.77

Step-by-step

1. Put the numbers in a vertical column, aligning the decimal points

2. Add each column of digits, starting on the right and working left. If the sum of a column is more than ten, "carry" digits to the next column on the left.

3. Place the decimal point in the answer directly below the decimal points in the terms.

The price of a share of stock for company XYZ at the beginning of the week was $23.99. Over the next five days, the share of stock gained $3.60 on Monday, lost $4.51 on Tuesday, gained $0.95 on Wednesday, gained $2.17 on Thursday, and lost $1.08 on Friday. What was the price of the share of stock at the end of Friday? Show your work.

Answers

$25.12

Work:

23.99+3.60=27.59

27.59-4.51=23.08

23.08+0.95=24.03

24.03+2.17=26.20

26.20-1.08=25.12

Answer:

The price of the share of stock was $25.12 at the end of friday.

Step-by-step explanation:

is the relation shown in the arrow diagram a function? explain
Input 1 3 4 3
Output 1 9 16 27
A.yes each input has only one output
B. yes each output has only one input
c.yes each output is the square of the input
D. no the input 3 has 2 outputs

Answers

Something can be described as a function if there is only 1 of each number in the input or x.
For example: (9,6) and (9,3) would not be a function because there are two 9’s as the input.

So, for this problem there are two 3’s meaning this is NOT function because there are two outputs for the same number.


Your answer is going to be D.

The given relation is not a function because input value 3 has 2 outputs.

What is Function?

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

Input 1 3 4 3

Output 1 9 16 27

A relation is a function when the inputs are distinct and have corresponding output.

So, the given relation is not a function because input value 3 has 2 outputs.

Your school district cancels school when at least 2.25 inches of snow accumulate on the ground each hour. Snow is currently accumulating at a rate of 7/4 inches per hour. Select an inequality that represents the extra snow accumulation s (in inches per hour) needed to cancel school. Then solve the inequality.

Answers

Answer:

Especially during a pandemic, there should be no worries about school-cancellation based on an increase of snow in the overall city you're in. All education should currently be online through digital learning and if your school is doing otherwise please have a talk with them, snow is currently not the main concern of the world pandemic.

Step-by-step explanation:

A inaquilaty would be S<2 1/4 because the s is the variable and the 2 1/4 would represent the 2.25 inches of snow

2m + 14 − 15 − 15m simplified

Answers

-13m - 1 is the simplified equation !

Answer:

-13m-1

Step-by-step explanation:

You want to combine all like terms

In this case, that would be 2m, -15m and 14, -15

When you add 2m to -15 m, it gets you to -13. Similarly, you can subtract 15 from 2, and get -13 as well. It depends on which method you prefer.

Then, you want to combine 14 and -15 using addition or subtraction. Add 14 to -15 and that gets you to -1. You can also subtract 15 from 14 and get -1 as well.

Step-by-step explanation:

Step 1: Define

[tex]\frac{4.5}{y} =\frac{12.5}{4}[/tex]

Step 2: Solve for y

Cross-multiply:                    [tex]4(4.5) = 12.5y[/tex]Multiply:                               [tex]18 = 12.5y[/tex]Isolate y:                              [tex]1.44 = y[/tex]Rewrite:                               [tex]y=1.44[/tex]

Step 3: Check

Plug in y to verify it's a solution.

Substitute:                    [tex]\frac{4.5}{1.44} =\frac{12.5}{4}[/tex]Divide:                          [tex]3.125=3.125[/tex]

Here, we see that 3.125 does indeed equal 3.125. ∴ y = 1.44 is a solution of the equation.
