Cynthia is training to run the 100 yard dash. The first week she ran it is 14.0 seconds. The third week she ran it in 13.1 seconds. What is the percent change from week 1 to week 3 rounded to the nearest tenth of a percent?

Answers

Answer 1

Answer:

6.43% change

Step-by-step explanation:

Have a good one

Answer 2

The percentage is calculated by dividing the required value by the total value and multiplying it by 100.

The percent change from week 1 to week 3 rounded to the nearest tenth of a percent is 6.4%.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying it by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

First week:

Time taken to run 100 yards = 14 seconds

Third week:

Time taken to run 100 yards = 13.1 seconds

The percentage change in the time from the first week to the third week:

= [(Time taken at the first week - Time taken at the third week) / Time taken at the first week ] x 100

= [(14 - 13.1) / 14] x 100

= 0.9/14 x 100

= 6.4%

This means that there is 6.4% from the first week to the third week.

Thus,

The percent change from week 1 to week 3 rounded to the nearest tenth of a percent is 6.4%.

Step-by-step explanation:

Hope that helps!

An example of two integers that make a zero pair is 6 and -6.

They are additive inverses because they sum up to zero

For two integers to make a zero pair:

They must be equal in magnitudeThey must have opposite signs

Let the first number be represented by x

For one to be the additive inverse of the other, the second number must be -x.

x  +  (-x)  

=  x  -  x

=  0

Answer:

Step-by-step explanation:

-5.9,5.75,5.9,0.58

Answer:

-5.9, 0.58, 5.75, 5.9

Step-by-step explanation:

Begin by writing all four numbers into the same form.  

We'll start with -5.9.

Next, 23/4 = 5 3/4 or 5.75

Next:  5.9 stays as such

Finally, 58%, a percentage, changes to 0.58

Then the four numbers are:

-5.9, 5.75, 5.9 and 0.58

-5.9 is the smallest (and is positioned furthest from the origin to the left.  

0.58 is the next smaillest; it's positive, whereas -5.9 is negative.

The next two numbers are

5.75 and

5.9

Least to greatest, we  have -5.9, 0.58, 5.75, 5.9

125 = 5³, and the given expression reduces to

[tex]\left(\sqrt{125}\right)^{\frac13}\cdot\left(\sqrt[3]{125}\right)^{\frac12}=\left(125^{\frac12}\right)^{\frac13}\cdot\left(125^{\frac13}\right)^{\frac12}=125^{\frac16}\cdot125^{\frac16}=125^{\frac13}[/tex]

so it has a value of 5.

Now:

• the first choice is equivalent, since 625 = 25², so

[tex]\dfrac{\sqrt[3]{625}}{5^{\frac13}}=\dfrac{25^{\frac23}}{5^{\frac13}}=\dfrac{5^{\frac43}}{5^{\frac13}}=5[/tex]

• the second choice is not equivalent, since

[tex]5 \cdot 25^{\frac13} = 5 \cdot 5^{\frac23} = 5^{\frac43}[/tex]

• the third choice is also equivalent, since

[tex]\dfrac{\left(\sqrt[4]{5}\right)^7}{125^{\frac14}}=\dfrac{5^{\frac74}}{5^{\frac34}}=5[/tex]

• the fourth choice is also equivalent, since

[tex]\dfrac{5^{\frac12}\cdot25^{\frac13}}{\sqrt[6]{5}}=\dfrac{5^{\frac12}\cdot5^{\frac23}}{5^{\frac16}}=\dfrac{5^{\frac76}}{5^{\frac16}}=5[/tex]

What is the slope of the line.

Answers

-4/5 is the skip of the graph

Answer:

-4/5

Step-by-step explanation:

The slope of the graph is -4/5. The slope is the change in y over the change in x. The y-value decreases by 4 and the x-value increases by 5. So the slope is -4/5. One visual way to check this is to remember that slopes that are fractions will make the line flatter, while numbers with absolute values greater than 1 make the slope steeper.

What is the area of this shape?
units squared

Answers

Answer: 19 units squared

Step-by-step explanation:

1) Use Area= 1/2bh to get the area of the two triangles, 15 and 4

2) Add the areas together

Answer:

19 units squared

Step-by-step explanation:

I have attached an image that explains the process.

Essentially we split the shape into 3 triangles, and solve the area of each, and add them up.

The top right triangle is 3 x 5. So A = (3 x 5) / 2 = 7.5

The bottom right triangle is a copy of the top right. So that A = 7.5

The triangle on the left is 4 long and 2 high. So A = (4 x 2) / 2 = 4 units.

Total area is:

7.5 + 7.5 + 4 = 19 units squared.

Both the range and domain stay the same. The domain stays the same, but the range changes. The range stays the same, but the domain changes.

Answer:

its b friends :)

Step-by-step explanation:

If the function shown is reflected across the y-axis create a new function. Both the range and domain stay the same.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that, the function shown is reflected across the y-axis to create a new function. We have to state the domain and range of each function.

The domain and/or range of a function will change when it is transformed. Only the domain will change if the inputs are only transformed. Only the range will change if the transformation only affects the outputs. The domain and range will change if the inputs and outputs are transformed simultaneously.

Thus, if the function shown is reflected across the y-axis creates a new function. Both the range and domain stay the same.
