The formula for the perimeter of a rectangle is P = 2(l + w). Which equation is NOT equivalent to the formula?

Answer:

a) 10.5

b) 25.32

Step-by-step explanation:

Plug in 2.3 for n in both equations.

First equation:

5 (2.3 - 2) + 9

5 (0.3) + 9

1.5 + 9

10.5

Second equation:

8 (2.3^2) - 17

8 (5.29) - 17

42.32 - 17

25.32

Answer:

it's 1!!

Step-by-step explanation:

Answer:

15x^2-14x-4

Step-by-step explanation:

(8x^2 * x-7x+2)+(7x^2 -7x-6)

you take out the parentheses

you add the common ones so -7x+-7x= -14x

8x^2 +7x^2 = 15x^2

and 2-6= -4

so in total it's 15x^2-14x-4

Answer: 11x^2 -16x-3

Step-by-step explanation:

Solution:

Your problem → (8x^2-7x+2) + (3x^2-9x-5)

(8x2-7x+2)+(3x2-9x-5)

=8x2-7x+2+3x2-9x-5

=8x2+3x2-7x-9x+2-5

=11x2-16x-3

Answer:

B

Step-by-step explanation:

because 4(x+3)=6x+16 is true

4(-2+3)=6(-2)+16

4(1)= -12+16

4=4

so the equation is true

Answer:

Positive Correlation

Step-by-step explanation:

The graph shown as a positive correlation.

Two variables move in the same direction in a positive correlation.

You can also tell that the graph has a correlation that is positive because of the line moving in a upward direction from left to right.

Hope this helps.  

Answer:

the second one the positive correlation

Step-by-step explanation:

the x and y are both positive

The graph shown as a positive correlation.

Two variables move in the same direction in a positive correlation.

You can also tell that the graph has a correlation that is positive because of the line moving in a upward direction from left to right.

==========================================

Explanation:

1/2 = 0.5

Every 60 days, the amount cuts in half.

We start with 904 grams and after 60 days, we have 904*0.5 = 452 grams left over.

After another 60 days, we have 452*0.5 = 226 grams left over.

-------------

Alternative Method:

We can apply the half-life formula.

y = a*(0.5)^(x/H)

where,

In this case,

When x = 120 days go by, we have....

y = a*(0.5)^(x/H)

y = 904*(0.5)^(x/60)

y = 904*(0.5)^(120/60)

y = 904*(0.5)^(2)

y = 904*(0.25)

y = 226 grams of antimony left over.

This method is preferred over the first method if you have x be some non-multiple of 60, or if x is fairly large.

Answer:

2.11

Step-by-step explanation:

3.5 x 2 + 9 = 16

10.4 - 1.4 x 2 = 7.6

16/7.6

= 40/19 or 2.11 to the nearest hundredth

Therefore the answer is 2.11

Answer:

h=200

Step-by-step explanation:

h/10+5=25

h/10=20

h=200

h/10 + 5 = 25

Subtract 5 from each side to get h/10 alone.

h/10 + 5 - 5 = 25 - 5

h/10 = 20

Multiply both sides by 10 to get h alone.

h/10 • 10 = 20 • 10

h = 200

h = 200. I hope this helps!

Answer:

I think the second one

Answer:

Hence, option: A is the correct answer.

A. As the x-values increase, the y-values tend to increase.

Step-by-step explanation:

It is given that:

A scatterplot has a positive, linear correlation.

By positive we means that as the x-value increases the y-value also keeps on increasing and by linear relation we mean that it increases somewhat by a constant amount so that the we get a line of best fit.

Hence, the statement which  is true about the relationship between the x- and y-values is:

A. As the x-values increase, the y-values tend to increase.

Answer:

a: As the x-values increase, the y-values tend to increase.

Step-by-step explanation:

28inch^2

Rectangle:

[Length x Breadth]

5 + 3 = 8inch

8 x 2.5 = 20inch^2

Right Triangle:

[1/2 x Base x Height]

1/2 x 5 x 2 = 1/2 x 10

= 5inch^2

Left Triangle:

[1/2 x Base x Height]

1/2 x 3 x 2 = 1/2 x 6

= 3inch^2

20 + 5 + 3 = 28inch^2

Step-by-step explanation:

1,15 is not the same ratio of 2,24

Answer:

No, because 1:15 is not the same ratio as 2:24.

Step-by-step explanation:

2/24 reduces to 1/12 not 1/15 so these ratios are not the same.

Answer:

I think the answer is B

Step-by-step explanation:

(I'm not great at math so pls don't use my answer unless its a last resort) Because when I divided each one they all ended up back at 4, with that being said; 4 ÷ 1 = 4 , 8 ÷ 2 = 4, 12 ÷ 3 = 4, and 16 ÷ 4 = 4. Those are in the c column.
