Answer:

i think a to c is dividing by 4.5

Step-by-step explanation:

Answer:

[tex]s\geq 45[/tex]

Step-by-step explanation:

First, we need to find out how many spoons Lily actually needs.

420-159=420-160-1=269

Next, we need to find out how many packs of spoons Lily needs.

269/6=44.83333333…

Now we need to round this number down and add 1.

44+1=45

Finally, we need make an inequality. Remember, “at least” means greater than or equal to.

[tex]s\geq 45[/tex]

Answer:

5,13

Step-by-step explanation:

If you divide 109/8= you get 13

The initial value is 5

the rate of change is 13 each month

5 cards + 13 x 8 months=109 cards

Answer:

45

6+30+48-1-9=45

Answer:

Step-by-step explanation:

we can start with process of elimanation.

f) wrong. this is because 12 is the second smallest number out of the four with ranch being the smallest with 8.

g) wrong. this is because 8x2=16, which means its not twice as likely it would end up. being more than twice as likely.

h) wrong. all of these numbers are different, so are smaller and bigger than others, so the rate of probability is going to be different for each chip type.

j) right. this is because if we do 8x2=16, that is still smaller than 20 so it is MORE than 2x as likely since 20 is a greater number than 16.

CORRECT ANSWER: J.

hope this helped!!

The statement which best supported is J) The flavor is more than twice as likely to be cheese as it is to be ranch.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Total number of chips = 12 + 18 + 8 + 20 = 58

Probability of finding Plain chips = 12/58 = 0.2069

Probability of finding Jalapeno chips = 18/58 = 0.3103

Probability of finding Ranch chips = 8/58 = 0.1379

Probability of finding Cheese chips = 20/58 = 0.3448

The flavor is least likely to be Ranch, not plain.

Twice the probability of Ranch = 0.2759

Hence the correct option is The flavor is more than twice as likely to be cheese as it is to be ranch.

Step-by-step explanation:

Answer:

Step-by-step explanation:

The percent decrease in Julia's monthly driving would be 35.9%. This is calculated by taking the difference between the two months (120 - 78 = 42) and dividing it by the initial amount (120) and then multiplying the result by 100. (42/120)*100 = 35.9%.

Her monthly driving decreased by 35%

Answer:

one half > three eighths

Step-by-step explanation:

yes.

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

to get the slope of any straight line, we simply need two points off of it, let's use those two in the picture below.

[tex](\stackrel{x_1}{6}~,~\stackrel{y_1}{194})\qquad (\stackrel{x_2}{8}~,~\stackrel{y_2}{178}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{178}-\stackrel{y1}{194}}}{\underset{\textit{\large run}} {\underset{x_2}{8}-\underset{x_1}{6}}} \implies \cfrac{ \stackrel{Lbs}{-16 }}{ \underset{Weeks}{2} } \implies \cfrac{\stackrel{Lbs}{-8}}{\underset{Weeks}{1}}\implies {\Large \begin{array}{llll} -8~\frac{Lbs}{Week} \end{array}}[/tex]

Answer: This situation cannot be true for any positive value of x. The valid range would be 0 < x < 4. If the x is less than 4, the perimeter of triangle 1 is always greater than triangle 2.

Explanation: We need to add up the lengths of the sides for obtaining the perimeters first.

Triangle 1: 5x + 57

Triangle 2: 11x + 33

Then, we need to build up an inequality for the case which the perimeter of triangle 1 is always greater than triangle 2.

This means => 5x + 57 > 11x + 33

If we write "x" values on one side:

24 > 6x

Then dividing by 6 for both sides:

4 > x

This means that a positive value of x should be less than 4 for this particular situation.

because you have to to the same thing to both sides

[tex]-7=\dfrac{1}{2} (z+12)[/tex]

Distribute:

[tex]-7=(\dfrac{1}{2} )(z)+(\dfrac{1}{2} )(12)[/tex]

[tex]\dfrac{1}{2} z+6=-7[/tex]

Subtract 6 from both sides:

[tex]\dfrac{1}{2} z+6-6=-7-6[/tex]

[tex]\dfrac{1}{2} z=-13[/tex]

Multiply both sides by 2:

[tex]2\times(\dfrac{1}{2} z)=2\times(-13)[/tex]

Answer:

-26

Step-by-step explanation:

1. distribute
1/2z+6=-7
-7-6=-13
1/2z=-13
-13 / 1/2 = -13 x 2/1 = -26
z = -26

double check:
1/2(-26+12)
1/2 (-14)

Answer:

A) solution 2 is more acidic than solution 1

Step-by-step explanation:

A chemist prepares two acid solutions:

Solution 1: 3 parts sulfuric acid to 7 parts water

Ratio of sulphur to water: 3/7 (3:7)

Solution 2: 4 parts sulfuric acid to 9 parts water

Ratio of sulphur to water: 4/9 (4:9)

___________________________________________________

Part A: (using ratios to determine which solution is more acidic)

First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.

Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63

Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63

Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.

Mathematical Line (Not sure what you would call this lol): 28 > 27

Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)

Equation of solution 1: y = 3/7x

Equation of solution 2: y = 4/9x

Please find attachment for graph.

Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)

Answer: 9oz pack is better. C.

Step-by-step explanation:

9 ounces=$2.52

3 ounces=$0.84

1 ounce=$0.28

12 ounces=$3.60

3 ounces=$1.20

1 ounces=$0.30

0.30-0.28=0.02

3 ounces cost more for the 12oz pack than the 9oz pack.

Explanation:

Let's rewrite each given fraction with a common denominator of 5*7 = 35.

1/5 = (1/5)*(7/7) = 7/35

1/7 = (1/7)*(5/5) = 5/35

Then we can see that 6/35 is between 5/35 and 7/35, since 6 is between 5 and 7.

Put another way:  5/35 < 6/35 < 7/35 since 5 < 6 < 7

This then means 1/7 < 6/35 < 1/5

Therefore, Maria's claim is incorrect.
