You just multiply 84 by two and then ad another 84.

Answer:

Step-by-step explanation:

Domain: ( - ∞ , ∞ )

Range: ( - ∞ , ∞ )

The "M" in M-value stands for "Maximum." For a given ambient pressure, an M-value is defined as the maximum value of inert gas pressure (absolute) that a hypothetical "tissue" compartment can "tolerate" without presenting overt symptoms of decompression sickness (DCS).

Answer:

12

Step-by-step explanation:

For these problems you should use the pythagorean theorem: a^2+b^2=c^2

In this case, 13=c and 5=a

so:

5^2+x^2=13^2

25+x^2=169

subtract 25 from both sides

x^2=144

√144=12

missing side=12

Answer:

the answer is

CO2 (1 atom of carbon and 2 atoms of oxygen)7.31x10-^23

3.34x10-^24 H2(2 atoms of hydrogen)

2821x 10-^23 NH3 (1 atom of nitrogen and 3 atoms of hydrogen

7.64x 10-^ 23 NO2 1 atom of nitrogen and 2 atoms of oxygen

Step-by-step explanation:

i got all of them right so these are all correct!!

The scale factor is 4.

Important information:

From the given figure it is clear that:

DG = 2

D'G' = 8

The scale factor is:

[tex]k=\dfrac{D'G'}{DG}[/tex]

[tex]k=\dfrac{8}{2}[/tex]

[tex]k=4[/tex]

Therefore, the scale factor is 4.

Answer:

17 is your answer

Step-by-step explanation:

Given a peicewise function, with two parts:

{f(x) = 4x+3 {if x<2}

f(x) = 5x+2 {if x>2}

f(3) = f(x) when x is 3, 3 > 2, 3 is not less than 2 so f(x) for x>2 is 5x + 2.

Therefore f(3) = 5(3) + 2 = 15 + 2 = 17

Answer:

Infinite number of solutions

Step-by-step explanation:

Write these equations in a column:

-6x+y=-21  

2x-1/3y=7

Use elimination by addition and subtraction. Start by multiplying the 2nd equation by 3, obtaining:

-6x+y=-21  

6x - y= 21

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

  0  - 0 = 0

There are an infinite number of solutions.  The two equations shown immediately above are multiples of one another.

Answer:

88

Step-by-step explanation:

Answer:

12 ×$0.75 =$8.00

3.75 ÷ 5 = $1.33 a pound,

$1.33 × 12 = $15.96 so store A is offering the best rate.

It is found that Store B is offering the best unit rate for the bananas.

There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.

Given that Grocery Store A is selling bananas 1/2 pound for $0.75 .

Grocery Store B is selling 5 pounds of bananas for $3.75.

According to the question,

Store A is selling bananas 1/2 pound for $0.75 .

Therefore,

For one pound will be;

= 0.75/0.5

= 1.5

And store B is selling 5 pounds of bananas for; $3.75

Therefore,

One pound will cost;

3.75/ 5 = 0.75

Hence, Store B is offering the best unit rate for the bananas.

Answer: 0.3 meters.

Step-by-step explanation:

First we need to turn one of those into a fraction or decimal to make things easier for us. Lets turn [tex]1 \frac{1}{5}[/tex] into a decimal.

1 1/5 as a decimal is 1.2.

Now we compare the two

[tex]1.5 > 1.2[/tex]

Now we need to subtract 1.5 by 1.2 to see how much more he jumps by.

[tex]1.5 - 1.2 = 0.3[/tex]

Steve jumps more by 0.3 meters.

Answer:

3/10 or .3 meters

Step-by-step explanation:

1 1/5 = 1.2
