Answer:

20 hamburgers

Step-by-step explanation:

We have 5 pounds of ground beef

We are making 1/4 pound hamburgers

Take the number of pounds of beef and divide by the amount of beef per burger and we can determine the number of patties.

5 ÷1/4

Copy dot flip

5 * 4/1

20

We will have 20 patties

                  Hello!

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

❖ Rayna can make 20 burgers.

Divide 5 by 1/4:

5 ÷ 1

     --

     4

When dividing, you flip the divisor and then multiply:

5 x 4       20

     --  =    ---  = 20

      1         1

Rayna is able to make 20 burgers.

Between 0 degrees Celsius and 30 degrees Celsius, the volume V (in cubic centimeters) of 1 kg of water at a temperature T is giv
Ira Lisetskai [31]

Answer:

T = 3.967 C

Step-by-step explanation:

Density = mass / volume

Use the mass = 1kg and volume as the equation given V, we will come up with the following equation

D = 1 / 999.87−0.06426T+0.0085043T^2−0.0000679T^3

   = (999.87−0.06426T+0.0085043T^2−0.0000679T^3)^-1

Find the first derivative of D with respect to temperature T

dD/dT = \dfrac{70000000\left(291T^2-24298T+91800\right)}{\left(679T^3-85043T^2+642600T-9998700000\right)^2}

Let dD/dT = 0 to find the critical value we will get

\dfrac{70000000\left(291T^2-24298T+91800\right)}  = 0

Using formula of quadratic, we get the roots:

T =  79.53 and T = 3.967

Since the temperature is only between 0 and 30, pick T = 3.967

Find 2nd derivative to check whether the equation will have maximum value:

-\dfrac{140000000\left(395178T^4-65993368T^3+3286558821T^2+2886200857800T-121415215620000\right)}{\left(679T^3-85043T^2+642600T-9998700000\right)^3}

Substituting the value with T=3.967,

d2D/dT2 = -1.54 x 10^(-8)    a negative value. Hence It is a maximum value

Substitute T =3.967 into equation V, we get V = 0.001 i.e. the volume when the the density is the highest is at 0.001 m3 with density of

D = 1/0.001 = 1000 kg/m3

Therefore T = 3.967 C

You can model that you expect a 1.25% raise each year that you work for a certain company. If you currently make $40,000, how ma
gizmo_the_mogwai [7]

Answer:

94 years

Step-by-step explanation:

We can approach the solution using the compound interest equation

A= P(1+r)^t

Given data

P= $40,000

A=  $120,000

r=  1.25%= 1.25/100= 0.0125

substituting and solving for t we have

120000= 40000(1+0.0125)^t \\\120000= 40000(1.0125)^t

dividing both sides by 40,000 we have

(1.0125)^t=\frac{120000}{40000} \\\\(1.0125)^t=3\\\ t Log(1.0125)= log(3)\\\ t*0.005= 0.47

dividing both sides by 0.005 we have

t= 0.47/0.005\\t= 94

A block of cheese is in the shape of a rectangle prism with a width of 2.5 inches in the height of 5 inches the volume of the bl
brilliants [131]
The formula for volume is l x w x h.

To find the missing link, we do the equation backwards.

l x 2.5 x 5 = 75

If we divide 75 by 5 then by 2.5, we get 6 which becomes our length.

To check, do 5 x 2.5 x 6 which should equal 75 

6 is your length
