Whrite 2 diffrent pairs of decimals whose sums are 14.1 .One pair sould involve regrouping

Nathan and his brother Zach love to play video games. Right now, Nathan's score is 11 less than 2 times Zach's score.-example, i

sashaice [31]

Zach's score, Z, and Nathan's score, N, are related by the formula

2Z-11=N.

This is further explained below.

<h3>What are algebraic expressions?</h3>

Generally, Assume Nathan has a score of N and Zach has a score of Z.

Zach's score is 11 points higher than Nathan's.

It implies,

N equals twice of Z minus 11.

We may format it as follows:

2Z - 11 = N

There are now four possible outcomes for these two brothers' scores:

Zach's score will be determined using algebraic formulas if Nathan's score is 81.

2Z - 11 = 81

2Z = 92

Z = 46

Zach's score will be 61 if Nathan receives a score of 111.

Zach's score will be 121 if Nathan's score is 231 or higher.

Zach's score will be 456 if Nathan's score is 901.

The formula 2Z - 11 = Z is a rule that connects Nathan's and Zach's scores.

Answer: .3, .1, .5, .6, .5

Step-by-step explanation:

$\large \dfrac{\text{quantity of shaded spaces}}{\text{Total spaces}}=\dfrac{3}{10}=\large\boxed{.3}\\\\\\\dfrac{\text{quantity of 5s}}{\text{Total spaces}}=\dfrac{1}{10}=\large\boxed{.1}\\\\\\\dfrac{\text{quantity of even numbers}}{\text{Total spaces}}=\dfrac{5}{10}=\large\boxed{.5}\\\\\\\dfrac{\text{Total - white spaces}}{\text{Total spaces}}=\dfrac{10-4}{10}=\large\boxed{.6}\\\\\\\dfrac{\text{white spaces + number of 7s}}{\text{Total spaces}}=\dfrac{4+1}{10}=\large\boxed{.5}\\$

I think that the trend that would be seen in the time column of the data table would be that the number of seconds would increase. I know this because for each flask, the concentration of sodium thiosulfate decreases, since less of it is being mixed with more water. Also, when the concentration of a substance decreases, then the reaction rate also decreases, as there will be fewer collisions with sulfuric acid if there are fewer moles of sodium thiosulfate. When there are fewer collisions in a reaction, the reaction itself will take longer, and so when the sodium thiosulfate is diluted, the reaction takes more time.

Hope this helps you and any others :)

Which is the better buy?

Morgarella [4.7K]

Answer:

3,805 pounds of cement for $266.35 is a better buy

Step-by-step explanation:

3,805 pounds of cement for $266.35

266.35 : 3,805= 0.07

check your work: 3,805 x 0.07 = 266.35

so for the first offer you will be paying $0.07 per pound

5 tons of cement for $1,400.00

1 ton = 2000 pounds

5 tons = 10000 pounds

1,400.00 : 10000 = 0.14

for the second offer you will be paying $0.14 per pound of cement. 3,805 pounds of cement for $266.35 is a better buy because you will be paying half of the price for each pound.

hope this helps!
