if you doubled a recipe that makes 2 doz. cookies how many cookies would you expect to make ​

Answer:

Your answer is: t = (1/2 * 6/12) / (5/12) (which equals) t=3/5 or in decimal form t= 0.6

Step-by-step explanation:

It says, " After 3 hours, she had completed half of the work" it means it would take all together Jen 6 hours to do the entire job.

It says, " together they finished everything in half an hour", so that means Jen does an a little bit more work, [1/2 / 6] or 1/12 for the entire job , and Maryna does 5/12 of the whole job in 1/2 hr.

Then, the equation would have been (5/12) / (1/2) = (6/12) / t, and the time for  Maryna to finish on her own  portion she would be doing 6/12 (half) of the whole job.

So therefore Your answer is: t = (1/2 * 6/12) / (5/12) (which equals) t=3/5 or in decimal form t= 0.6 :)

Step-by-step explanation:

The ice has more thermal energy because it is a solid and the water is a liquid. The water has more thermal energy because the molecules of the water are moving faster than the molecules of the ice. The water and the ice have the same amount of thermal energy because they are different forms of the same substance.

Answer:

The Marked Price is 63.75

Step-by-step explanation:

15/100 * 75 = 11.25

75 - 11.25 = 63.75

Hence the Marked Price is 63.75

Answer:

x=8

Step-by-step explanation:

this is a right angle and right angles are 90 degrees. 6*8 equals 48+2 equals 50. 50+40 equals 90!

Answer:

x=8

Step-by-step explanation:

you would subtract 40 from 90 which gives you 50. you would then set 6x+2 equal to 50 and solve from there.

Answer:

15

Step-by-step explanation:

We can start by trying to figure out the divisors for each number. A divisor is a whole number that we can multiply by another whole number to equal our target number.

For example, 2's divisors would be 2 and 1, because we can multiply 2 and 1 together to get 2.

30's divisors would be: 1, 30, 2, 15, 3, 10 4, 5, 6

45's divisors would be: 1, 45, 3, 15, 5, 9

75's divisors would be: 1, 75, 3, 25, 5, 15

We should start with 30's divisors because we're searching for a greatest common divisor, so we have to make sure that divisor still fits into the smallest number. Additionally, we should go from biggest to smallest because by eliminating the highest possibilities first, we can ensure that our answer will be the biggest possible one without having to check every single one.

30's biggest divisor is 30, but neither 45 nor 75 have it. 30's next biggest divisor is 15, and that is a common divisor between 45 and 75. Since we worked from the biggest to the smallest, we also know that it is the highest possible common divisor.

That means the G.C.D. of 30, 45, and 75 is 15.

Answer:

the answer is B

The cost of the computer is a function of the amount of memory.

the question doesn't talk about the brand. only cost of the computer and the amount of memory.

it says that "She knows that the more memory the Computer has, the more expensive it will be"

Answer:

m(n) = 60000

Amount = 60000/n

Step-by-step explanation:

Given

Budget = 60000

Solving (a) Represent as a function mn

To do this simple substitute m(n) for Budget.

This gives;

m(n) = 60000

Solving (b) Amount each committee will receive.

Since the amount will be shared evenly.

Amount = m(n)/n

Substitute 60000 for m(n)

Amount = 60000/n

Answer:

h^-1(x)=(x-1)/2

Step-by-step explanation:

We can rewrite the function as y=2x+1, switch the y and x, x=2y+1, and simplify to y=(x-1)/2.

Answer:

9. answer: -3, 10. answer: 5

Answer:

Here

Step-by-step explanation:

7 = 4x + 7

Cancel out the 7's on each side by adding negative 7 to both sides...

0 = 4x

Now find how much for x alone

4x = 0

divide both sides by 4

x = 0

X = 0

7 = 0 + 7

7 = 7

Answer:

y = -5 + 2x

Answer:

2 pi/3

Step-by-step explanation:

Step 1: Know the Equation of a Trig Function

[tex]y = a \sin(b(x - c)) + d[/tex]

where |a| is the amplitude

The period is

[tex] \frac{2\pi}{ |b| } [/tex]

The phase shift is c.

Vertical shift is d.

So first, identity b. Here b is the 3.

So use the formula for a period.

Step 2: Computation.

[tex] \frac{2\pi}{ |b| } = \frac{2\pi}{3} [/tex]

So the period is 2 pi/3

What does this mean?

This means every 2 pi/3, the function will repeat itself. which is called oscillation.

Answer: 1/5

Step-by-step explanation:

Simplify the fraction by dividing both the numerator and denominator by 2

Answer:

[tex]v=\frac{48}{5}=9\frac{3}{5} \\ [/tex]

Step-by-step explanation:

[tex]\frac{8}{5}=\frac{v}{6}[/tex]

Swap sides:

[tex]\frac{v}{6}=\frac{8}{5}[/tex]

Multiply to both sides by 6:

[tex]\frac{v}{6}\cdot6=\frac{8}{5}\cdot6[/tex]

Group like terms:

[tex]\frac{1}{6}\cdot6v=\frac{8}{5}\cdot6[/tex]

Simplify the fraction:

[tex]v=\frac{8}{5}\cdot6[/tex]

Multiply the fractions

[tex]v=\frac{8\cdot6}{5}[/tex]

Simplify the arithmetic:

[tex]v=\frac{48}{5}[/tex]

Answer:

y = x - 2

Step-by-step explanation:

1. Find the slope - change in y/change in x

[tex]\frac{0-(-1)}{2-1}[/tex] = 1

Slope is 1

2. Find y-intercept

y = x + b

Substitute a point (2,0)

0 = 2 + b

b = -2

3. Put the equation together

y = x - 2
