Answer: It contains 88 g of zinc.

Step-by-step explanation:

Given: The ratio of zinc to copper is 4 to 13.

Ratio can be written as [tex]\dfrac4{13}[/tex]

A jar of the chemical contains 286 g of copper.

Let the quantity of zinc be x.

By using the direct proportion rule:[tex]\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}[/tex]

[tex]\dfrac{x}{286}=\dfrac{4}{13}\\\\ x=\dfrac{286\times4}{13}\\\\\Rightarrow\ x=88[/tex]

Hence,  It contains 88 g of zinc.

Answer:

-12

Step-by-step explanation:

Each dash is +-4

The answer would be .35 cent.

Answer:

The price per inch is $0.35

Step-by-step explanation:

First you have to convert 5 feet into inches.

5·12= 60.

Then, divide the 21 by 60.

21/60 = 0.35

In conclusion, it costs $0.35 per inch.

Answer:

sales Tax = 4.8

total cost = 84.8

Step-by-step explanation:

80.00 * 6%​ = 80.00 * 0.06​ = 4.8

Answer:

Sales tax: 4.80 Total costs: 84.80

Step-by-step explanation:

Price x sales tax rate = sales tax

80 x .06(6%) = 4.80

price + sales tax = total costs

80 + 4.80 = 84.80

Answer: A, i think -_-

Answer:

A= 2.50x+82.50x+8

B= 0.50x+240.50x+24

Step-by-step explanation:

Plan A is $4 cheaper than Plan B when watching 6 movies.

Answer:

10:30PM on the next day

Step-by-step explanation:

First movie = 85mins

intermission = 5mins

  Total time = 90mins which is 1:30PM

so the first movie will start again at  1:30PM, which is at the interval of 90minutes and it will run continuously.

Similarly the second movie is 110 minutes long + 5mins intermission which is 115minutes

Time = 1:55PM

so the second movie starts again at 1:55PM and runs continuously at an interval of 115minutes.

We are interested to find when both the movie will start again at the same time, this will be least common multiple of 90 and 115.

LCM of 90,115 = 2070

Therefore after 2070minutes movie will start again at the same time.

2070mins = 34hours and 30 minutes

adding this with noon

10:30PM on the next day.

Answer:

sorry i wish i knew how but i would like to give you aomething other than an answer for your question and i hope this is ok.

Step-by-step explanation:

every day is a new day and a new opportunity to change the world no matter how BIG or how small.  even if you make mistakes. always remember this though. whatever you put into the world, whether it be good or bad, it will always come back three times.

meaning that when you do something good something three times as good will happen to you. The same is so for bad except it would be 3 times as bad as will happen to you.   I hope your day is great and may you do many great things.

Answer:

x = 25

Step-by-step explanation:

15.2 * 0.25 - 48.51 ÷ 14.7 = 76/5 * 1/4 - 3.3 = 3.8 - 3.3 = 0.5

(13/44 - 2/11 - 5/66 ÷ 2 1/2) * 1 1/5 = (13/44 - 8/44 - 5/66 * 2/5) * 6/5 =           (15/132 - 4/132) * 6/5 = 11/132 * 6/5 = 1/12 * 6/5 = 1/10

3.2 + 0.8 * (5 1/2 - 3.25) = 3.2 + 4/5 * (22/4 - 13/4) = 3.2 + 9/5 = 3.2 + 2.8 = 5

So after doing all this simplifying and stuff we get 0.5/x = 0.1/5. Using the butterfly method the result is 0.1x = 2.5, multiply both sides by 10 and you get x = 25!! Yayy lol

Answer:

11/12

Step-by-step explanation:

Fraction of smoothie that is Banana = 1/4

Fraction of smoothie that is strawberry = 2/3

The fraction of smoothies that were either banana or strawberry

= 1/4 + 2/3

Least Common Denominator= 12

= (3 × 1 + 2 × 4)/12

= 3 + 8/12

= 11/12

The fraction of smoothies were either banana or strawberry is 11/12

Answer:

Q.1 - 10

Q.2 - −54

Step-by-step explanation:

Answer:

0 = 208 - 12x

Step-by-step explanation:

Since after 5 days the tree only had 208 leaves remaining, assuming that the rate of decay is constant, we can use the following equation to calculate the total number of days (starting at the 5-day mark as 0) until the tree loses all of its leaves. In this equation, the total number of days is represented by the variable x.

0 = 208 - 12x

Now that we have the equation we can solve it...

0 = 208 - 12x ... subtract 208 on both sides

-208 =  -12x   ... divide both sides by -12

17.33 = x

Finally, we can see that after 18 days (not 17.33 because we are counting full days) the tree will have lost all of its leaves.

Answer:

this is a linear function

Step-by-step explanation:

y = a + bx

in this case:

y = 800 - 114.29x

where:

y = accumulated depreciation

x = number of years

year     accumulated          

(x)         depreciation (y)      

0          0                      

1          114.29              

2          228.58                  

3          342.87                

4          457.16                  

5          571.45                  

6          685.74                  

7          800                

Given:

A submarine dives below the surface, heading downward in 5 moves.

Each move downward = 200 feet

To find:

The location of submarine after it is finished diving.

Solution:

According to the question,

1 move downward = 200 feet

5 move downward = 5 × 200 feet

                               = 1000 feet

Since, the submarine heading downward in 5 moves, therefore the submarine is 1000 feet downward after it is finished diving.
