Answer:

18

Step-by-step explanation:

Slope, rate of change, unit rate, speed are <em>synonyms</em>

y = mx + b

Slope "m" is a rate of change.

~~~~~~~~~~

C = 18h + 35

m = 18

Boris chooses three different numbers the sum of the three numbers is 36 one of the numbers is a cube number the other two numbe
OlgaM077 [116]

Answer:

3,4,5

Step-by-step explanation:

Here, we need to asume that the values are integers, as if not, there will be infinite solutions.

Lets go by parts:

The 1st number is a cubic, lets call it A

The second is a factor of 20, lets call it B. The same for the 3rd, call it C.

So, A + B+ C = 36

There are no many factors of 20, those are the numbers that when multiplied gives as the value of 20. Those are 1, 2, 4, 5, 10 and 20. So, B and C are some of these numbers.

Then, we know A if less than 36, other way the whole sum will be greater than 36. How many cubic number with integer cubic roots are less than 36? Well, lets guess:

1^3 = 1 -> valid, as it is less than 36

2^3 = 8 -> valid, as it is less than 36

3^2 = 27 -> valid, less than 36

4^3 = 64 -> not valid, as it is greater than 36

So, A ir 1, 2 or 3.

If A is 1, then B+C needs to be 35. But, from the factors of 20 that we listed, there are no combinations of 2 numbers that sum 35. So, A CAN'T be 1.

If A = 2, then we have:

8 + B + C = 36

B + C = 28

And again, there are not combinations of two factors of 20 that sum 28 (try yourself).

If A=3:

27 + B + C = 36

B +C = 9

And we have a winner!!! If B=4 and C=5 (or viceversa C=4 and B=5)

27 + 4 + 5 = 36

So, A=3, B=4 and C=5 or A=3, C=4 and B=5 are solutions.

Assume 2 kg of apples is 1 dozen and that each apple has 8 seeds. How many apple seeds are in 14 kg of apples?
Drupady [299]

Answer:

There are 672 seeds in 14 kg of apples

Step-by-step explanation:

2 kg of apples = 1 dozen

1 dozen = 12 apples

So, 2 kg of apples =12 apples

1 kg of apples = \frac{12}{2} apples

1 kg of apples = 6 apples

14 kg of apples =6 \times 14=84 apples

Each apples has 8 seeds

So, 84 apples has seeds = 8 \times 84= 672 seeds

Hence there are 672 seeds in 14 kg of apples
