Answer:

24 pounds of apples for $60

about 3 apples per pound

about 72 apples for $60

Step-by-step explanation:

$15 times 4 = $60, therefore 6 pounds times 4 = 24 pounds

5 out of 16 ounces equals about 3 apples per pound

24 pounds, with 3 apples in each pound, equals 72

Substituting u = 6x - 5, you write

y = cos(u)

Then differentiating with the chain rule gives

dy/dx = dy/du • du/dx

We have

dy/du = -sin(u)

du/dx = 6

so

dy/dx = -6 sin(u) = -6 sin(6x - 5)

Answer:

3

Step-by-step explanation:

"Rate of change" is the real-world problem way of saying "slope."

So whenever a question asks you to find "rate of change", simply look for the slope.

y = mx + b

e = 3h + 200

mx = slope/rate of change

So, 3 would be your answer.

Answer:

1.33333333quarts

1.3(repeating) quarts

Step-by-step explanation:

Answer: 18 quarts

Step-by-step explanation:

As per given,

Quantity of sparkling juice is proportional to quantity of course with grape juice.

Given: A free cable sparkling juice calls for [tex]1\dfrac12[/tex] quarters of sparkling water and [tex]\dfrac34[/tex] course with grape juice .

Let x be the quantity of sparkling water need to mix with 9 quarts of grape juice.

then, by equation of direct proportion , we have

[tex]\dfrac{1\dfrac12}{\dfrac34}=\dfrac{x}{9}\\\\\Rightarrow\dfrac{\dfrac{3}{2}}{\dfrac{3}{4}}=\dfrac{x}{9}\\\\\Rightarrow\ \dfrac21=\dfrac{x}{9}\\\\\Rightarrow\ x=9\times2\\\\\Rightarrow\ x=18[/tex]

Hence, the quantity of sparkling water need to mix with 9 quarts of grape juice = 18 quarts

Answer:

3:15PM

Step-by-step explanation:

If If Diana got out of school at 1:40 P.M, this and spent 1 hour 35 minutes at the rehearsal, to know the time that the choir rehearsal ends, we will have to add the time spent at rehearsal to the time he got out of school;

1:40 P.M + (1hr 35 minutes)

1:40 P.M + 1 hr = 2:40PM

2:40PM + 35mintes = 2:40PM + (20mintes) +15 minutes

[2:40PM + (20mintes)] +15 minutes = 3:00pm + 15 minutes

3:00pm + 15 minutes = 3:15PM

Hence the choir rehearsal ends at 3:15PM

Answer:

25/3

Step-by-step explanation:

Set the equations equal to each other since the lines are parallel.

(x+20)=(4x-5)

-x  +5       -x   +5

25/3 = 3x/3

x = 25/3

Step-by-step explanation:

Answer:

r = V/2 - 2

Step-by-step explanation:

Answer:   r=1/2v−2

Step-by-step explanation:

v=4+2r

2r+4=v

2r+4+−4=v+−4

2r=v−4

2r/2=v−4/2

r=1/2v−2

Answer:

The maximum a person can weigh to go on the ride safely is 100.5 kg

Step-by-step explanation:

The specification for the maximum weight of each person that goes on the ride = 100 kg

Therefore, given that the maximum possible error of a measurement is equal to 1/2 multiplied by the unit of measurement, we have that the specified maximum weight, [tex]W_{max}[/tex], can be written as follows;

[tex]W_{max}[/tex] = (100 ± 0.5) kg, which gives the maximum a person can weigh to go on the ride safely as 100 kg + 0.5 kg = 100.5 kg

Answer:

x = 12

y = 14

Step-by-step explanation:

5x + 4y = 116

5 x 12 = 60

4 x 14 = 56

60 + 56 = 116

10x + 6y = 204

10 x 12 = 120

6 x 14 = 84

120 + 84 = 204

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

Here's how I found x and y:

10x + 6y = 204 can be divided by 2

5x + 3y = 102

Then I took 116 and subtracted 116 given the difference

in y.

116 - 102 = 14

So y =  14 and then I sovled for x:

5x + 56 = 116

116 - 56 = 60

60/5 = 12

10x + 84 = 204

204 - 84 = 120

120/10 = 12

Answer:

picture from Goldbach's conjecture.

Step-by-step explanation:

Goldbach's conjecture is one of the oldest and best-known unsolved problems in number theory and all of mathematics. It states:

Every even integer greater than 2 is the sum of two primes.

The conjecture has been shown to hold for all integers less than 4 × 10^18, but remains unproven despite considerable effort.

So on the red and blue axes you see primes. The list of black numbers are even numbers.

Answer: C) Neither positive nor negative -- the sum is zero

Adding any positive number to its negative counterpart always leads to 0.

We could come up with a story problem where a person has $37 in their bank account, and then they take out $37 which is represented with the negative number. This leads the balance to become 37+(-37) = 37-37 = 0 dollars.

Answer:

43-5= 38 (subtract the y-intercept from the last number to see how many stamps were sold over the past two months)

38/2= 19 (the number of stamps sold over 2 months divided by how many months it took for those stamps to be sold)

19 is what goes in the box
