Answer:

18.72

Step-by-step explanation:

cost of four cartons = $ 5.76

cost of one carton = $ 5.76/4

cost of 13 cartons= $ 5.76/4× 13

=$ 18.72

Step-by-step explanation:

Cost of four cartons: 5.76

Cost of one carton: 5.76/4 times 13.

Cost of 13 cartons: 5.76/4 times 13 = 18.72

Answer:

75 (.2)= 15

75-15=60

The small bag cost $60.

Step-by-step explanation:

Answer:

The small size cost $60.

Step-by-step explanation:

The large backpack cost $75 and cost 20% more than the small one.

75 x 0.20 = 15

75 - 15 = 60

Answer:

i think you use y=mx + b to find the answer but  im not 100% on it

Answer:

0.6

Step-by-step explanation:

6 - 9      -3

-------- = ------- = 0.6

-3 - 2       -5

since the formula m=y^2 - y^1 means 6 - 9        -3

                                  -------------= .       ----------- = ------- = 0.6

                                  x^2 - x^1             -3 - 2         -5

The slope of the line is 0.6

21. 4x^2 - 2 + 5x^3

22. 7a^2 + 9y - 4y^4 + 6

23. b^5 + 5

24. -9a + 3z - 7z^3 + 5

25. 3r^2

Step-by-step explanation:

I don't know if I did it correctly but based on what I understand I think this is how you do this exercise.

Example: 5x^2 - 2x + 1 < This is a Trinomial because it has three terms, but there is more to it.

In 5x^2 - 2x + 1, the highest exponent is 2 (^2 from 5x^2) < therefore this is a 2nd-degree Trinomial.

Another example: 3x^4 + 4x^2 < This is a Binomial (two terms) but there's more to it.

In 3x^4 + 4x^2, there are two different exponents 4 and 2, but we are focusing on the highest exponents which is 4 (^4 from 3x^4) < therefore this a 4th-degree Binomial.  

Hope this can help you in the future!

Answer:

3333333333333ddese

Step-by-step explanation:

Answer:

x = -3

Step-by-step explanation:

-12 = 6x + 6

Start by subtracting 6 from both sides to get the 6x alone on the right.

-18 = 6x

Divide both sides by 6 to find out what x equals

x = -3

Answer:

X = -3

Step-by-step explanation:

move the variable to the left hand side and change its sign

Answer: 64% = 16/25 = 0.64; 12.5% = 1/8 = 0.125; 140% = 1 2/5 = 1.4; 275% = 2 3/4 = 2.75; 8% = 2/25 = 0.08

Answer:

3+105

Step-by-step explanation: Im so sorry if its wrong

Answer:

Simplified Expression: 3d + 105

Step-by-step explanation:

You have to distribute the number outside the parenthesis (3) to the number(s) inside the parenthesis (d + 35).

You can rewrite it like this: (3)(d) + (3)(35)

Answer:

C

Step-by-step explanation:

Let's see if this makes sense and applies to all of the pairs.

1. y will be 2

x will be 6

2=1/3(6)

1/3 times 6 is 2.

2. y will be 1

x will be 3

1=1/3(3)

1/3 times 3 is 1.

3. y will be 0

x will be 0

0=1/3(0)

1/3 times 0 is 0.

4. y will be -1

x will be -3

-1=1/3(-3)

1/3 times -3 is -1.

They all apply to C meaning that C is the right answer.

Answer:

1) A. y= 3x

2)B.

3) C

4) B. 38mm (This answer MAY be wrong, it may be right aswell though.)

Answer:

Supplementary, 39+5x=180, x=28.2

Step-by-step explanation:

So we know that a straight line is 180 degrees, therefore 52+(5x-13) must equal 180. This is a supplementary relationship. That's our equation, now we just have to solve.

52+5x-13=180

We can straight away combine numbers, giving us

39+5x=180

Now we subtract 39 from both sides, giving us

5x=141.

Now we will answer.

141/5=28.2=x

I'm not sure if this is right, but this is my answer :)

Answer:   so, i only know number 6 which is human fertilization

Answer: 6. when sperm and eggs combine its called a zygote.

7. The diploid number for humans is 46 chromosomes. The haploid number  is 23 or n=23.

8. Matching chromosomes are called homologous pairs.

9. During prophase 1 of meiosis these pairs form a tetrad process called crossing over or recombination.

10. When homologous chromosomes exchange genes it's called synapsis.

11. 2 daughter cells are created at the end of meiosis 1 and 4 are created at the end of meiosis 11.  

12. During the meiosis chromosomes will split into daughter cells randomly making each gamete unique this is called Cytokinesis.

13. The process by which sperm is made is called Sertoli cells.

14. The process by which eggs are made is called oogenesis.

15. During the creation of an oocyte, 3 additional haploids are created that will not be fertilized these cells are called Polar bodies.

Answer:

20 square units

Step-by-step explanation:

[tex]c = \sqrt{ax^{2} + bx^{2}} = \sqrt{12x^{2} + 16x^{2}} = 20[/tex]

Answer:

a 25 square units

Step-by-step explanation:

first find the length of the two sides of the triangle (sides of square 1 and 2)

the perimeter of a square is the length of the side × 4

so to find the length of the side, divide the perimeter by 4

perimeter of square 1: 12 units

divide it by 4: 3 units, so that's the length of side 1

perimeter of square 2: 16 units

divide it by 4: 4 units, so that's the length of side 2

now use a2 + b2 = c2

3 squared + 4 squared = c2

and solve

9 + 16 = c2

25 = c2

square root of 25 = square root of c2

5 = c

So now multiply 5 × 5 to find the area of the square

25

9+7=16

16-9=7

7-4=3

Answer:

C

Step-by-step explanation:

Answer:

a. 1

b. -5

c. -9

d. -2

e. 11

Step-by-step explanation:

a. -7 = 3a-10

-7+10 = 3a

3 = 3a

a = 1

b. 2a+13 = 3

2a = 3-13

2a = -10

a = -10/2

a = -5

c. -5a+14 = 59

-5a = 59-14

-5a = 45

-a = 9

a = -9

d. -23 = 4a-15

-23+15 = 4a

-8 = 4a

-2 = a

a = -2

e. -90 = 9-9a

-90-9 = -9a

-99 = -9a

-99/-9 = a

11 = a

a = 11
