what do you add to 2/9 to make it a whole

Answer:

B

Step-by-step explanation:

497.25/19.5=25.50

Answer:

B. $25.50

Step-by-step explanation:

if Emilio worked for 19.5 hours to earn $497.25 then how much wldid he earn perhour? ylwhen you put this in equation form

19.5h=$497.25

1h=? (so you crisscross them)

so 1h×$497.25÷19.5h (hour is divided by itself=1)

so Emilio earned $25.50 per hour.

Answer:

y=2(x square)-2x-3

Step-by-step explanation:

Let dy with y varibles in a hand

And dx with x variables on the other hand

dy=(4x-2)dx

Then by integration

y=2(square x)-2x+constant

Then substitute by x=-1 and y=1 to find the value of the constant

1=2(1)-2(-1)+ constant

Then constant=-3

Then the equation is

y=2(x square)-2x-3

Answer:

Answer:

Step-by-step explanation:

The combinations are defined as

[tex]C^{r}_{n}=\frac{n!}{(n-r)!}[/tex]

Where [tex]n[/tex] is the total number of elements and [tex]r[/tex] is the number of letter we are gonna picke, which is two. Using this information, we have

[tex]C^{2}_{6}=\frac{6!}{(6-2)!}=\frac{6!}{4!}=\frac{6 \times 5 \times 4!}{4!}=30[/tex]

Therefore, there are 30 possible combinations of picking two letters.

Hey!!

Solution,

Radius(r)=1

Area of circle=?

Now,

Area of circle= pi (r)^2

= 3.14* (1)^2

=3.14* 1

=3.14 units^2

So the right answer is 3.14 units^2.

Answer:

8/100 = 2/25 = .08

Step-by-step explanation:

Answer:

4.The product is greater that 3/8 and less than 7/2.

Step-by-step explanation:

The product of 3/8 and 7/2 is:

[tex]\frac{3}{8} * \frac{7}{2} \\\\= \frac{21}{16} = 1\frac{5}{16}[/tex]

This number is greater than 3/8.

It is greater than 1/8 but not less than 1/2.

This number is less than 7/2.

This number is greater than 3/8 and it is less than 7/2.

Hence, the correct options is 4.

Answer:

b = 5

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

12^2 + b^2 = 13^2

144+b^2 =169

Subtract 144 from each side

144-144+b^2 = 169-144

b^2 = 25

Take the square root on each side

sqrt(b^2) = sqrt(25)

b = 5

B= 5

The current weight of the octopus is:

[tex]w = \frac{14}{15}\,kg[/tex]

Step-by-step explanation:

The current weight is determine by addition and subtraction of rational numbers:

[tex]w = \frac{5}{6}\,kg + \frac{3}{10}\,kg -\frac{1}{5}\,kg[/tex]

[tex]w = \frac{50 + 18}{60}\,kg - \frac{1}{5}\,kg[/tex]

[tex]w = \frac{68}{60}\,kg - \frac{1}{5} \,kg[/tex]

[tex]w = \frac{17}{15}\,kg - \frac{1}{5}\,kg[/tex]

[tex]w = \frac{85-15}{75} \,kg[/tex]

[tex]w = \frac{70}{75}\,kg[/tex]

The current weight of the octopus is:

[tex]w = \frac{14}{15}\,kg[/tex]

Answer:

Step 1: Equation 1 can be multiplied by 2, Multiplying Equation 2 by 5

Step 2: divide by 21

Step 3: substitute 3 for y in one of the equations

Step 4: add 6

Step 5: divide both sides of the equation by 5

Step-by-step explanation:

The solution for the given set of equation 5x - 2y = -11  and -2x + 5y = 17 is  x = -1 and y = 3.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

The given set of equation is,

5x - 2y = -11       (1)

-2x + 5y = 17      (2)

Find the value of x from equation (2),

-2x + 5y = 17

2x = 5y - 17

x = (5/2)y -17/2

Substitute the value of x in equation (1),

5((5/2)y -17/2) - 2y = -11

25y/2 - 85/2 - 2y = -11

21y/2 = 63/2

y = 3

Substitute the value of y in equation (2) to get the value of x,

-2x + 15 = 17

x = -1

The value of x is -1 and y is 3.

The additive inverse for the x coefficient in equation (2) is 2x.

Answer:

Step-by-step explanation:

8.3+6.6=14.9

Answer:

4, 5 and 27.

Step-by-step explanation:

There are 2 cube numbers between 0 and 36 .

They are 8 and 27.

36 - 27 = 9 so the other 2 numbers could be 4 and 5 because they are both factors of 20.

36 - 8 = 28  whose factors are 2 * 2 * 7 which are not factors of 20.

Answer:

Step by step: you need to divide the top and multiple by the bottom. 12 divided by 3 is 4, and 4 times 4 is 16

Answer:

16

Step-by-step explanation:

The formula to solve for this is [tex]\frac{is}{of}=\frac{percent}{100}[/tex]

Here the 12 is our "is", the "of" is the [tex]\frac{3}{4}[/tex] , and the "percent" is what we are solving for so we can replace it for "x"

So now replacing our values we have [tex]\frac{12}{\frac{3}{4} } =\frac{x}{100}[/tex]

Cross multiplying we get [tex](12)(100) = (x)(\frac{3}{4} )[/tex]

Which then simplifies to

Then multiplying both sides by 4 to get rid of the fraction we get 4800% = 3x

The we need to divide by 3 and we get 1600% = x

Now this is in a percentage, so we need to divide 1600 by 100 to turn it into a whole number which comes out to x = 16

Answer:

$66.80

Step-by-step explanation:

The monthly payment can be computed using the pmt formula in excel spreadsheet as shown below:

=pmt(rate,nper,-pv,fv)

the rate is the interest rate of 3.5% divided by 12 months to show interest rate per month

nper is the number of months it would take to complete the payments which is 4 years multiplied by 12 months i.e 48 months

pv is the cost of the gadget at $2,988

fv is the sum of all month payments which is not unknown

=pmt(3.5%/12,48,-2988,0)=$66.80
