Answer:

1st term = 7, 2nd term = 18, 3rd term = 39, 10th term = 403

Step-by-step explanation:

To find the 1st term substitute 1 for n in the equation:

4(1)² + 1 = (4 × 1) + 3 = 4 + 3 = 7

To find the 2nd term substitute 2 for n in the equation:

4(2)² + 3 = (4 × 4) + 3 = 16 + 3 = 18

To find the 3rd term substitute 3 for n in the equation:

4(3)² + 3 = (4 × 9) + 3 = 36 + 3 = 39

To find the 10th term substitute 10 for n in the equation:

4(10)² + 10 = (4 × 100) + 3 = 400 + 3 = 403

Answer:

83 in^3

Step-by-step explanation:

We will need to find the volume of the cube, and then subtract the volume of the pyramid to find the space between.

Volume of pyramid = lwh/3 = 41.67

Volume of cube = lwh = 5*5*5 = 125 Subtract these 2 to get

125-41.67 = 83.33

Answer:

Step-by-step explanation:

x + y = 16

.75x + .65y = 11

75x + 65y = 1100

-75x - 75y = -1200

-10y = -100

y= 10 organes

x + 10 = 16

x = 6 apples

x= 6 apples

y = 10 oranges

Answ1/6

Step-by-step explanation:

1/3 divided by 2

we can change the division sign into multiplication by flipping it and this will also inverse 2

so now we will have

1/3 x 1/2

=1/6

Answer:

60

Step-by-step explanation:

since 15 apples makes 3 pies you divided 15 by 3 and get 5. 5 apples for one pie so that would be 5 x 12 = 60

Answer:

Since with 15 apples we are able to make 3 pies, this means that in each pie there are 5 apples (15apples divided by 3 pies = 5 apples.)

If there are 12 pies we simply have to multiply 12x5 which equals 60, this means that if we needed to make 12 pies we would need 60 apples.

15apples:3pies   =   60apples:12pies

Answer:

Factoring w2-16w+19

The first term is, w2 its coefficient is 1 .

The middle term is, -16w its coefficient is -16 .

The last term, "the constant", is +19

Step-1 : Multiply the coefficient of the first term by the constant 1 • 19 = 19

Step-2 : Find two factors of 19 whose sum equals the coefficient of the middle term, which is -16 .

-19 + -1 = -20

-1 + -19 = -20

1 + 19 = 20

19 + 1 = 20

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

w2 - 16w + 19 = 0

Step-by-step explanation:

Multiply 56 by 7/8 to determine the amount of red marbles.

*56 can be put over 1.

Multiply;

[tex] \frac{56}{1} \times \frac{7}{8} = \frac{392}{8} [/tex]

Simplify by dividing by 8;

[tex] \frac{392 \div 8}{8 \div 8} = \frac{49}{1} [/tex]

There are 49 red marbles.

Answer:

6/11 games

Step-by-step explanation:

Take the total number of wins, losses, and ties, and add them up to get the total number of games.

3+2+6=11

Then divide the wins by the number of games to get the fraction.

6/11

Answer:

If the 7 x 2 is in parenthesis then you would do the 7 x 2 first then do 14 by the power of 3. If there is no parenthesis and the power of 3 is hovering next to the 2 then you would do 2 to the power of 3 and then multiply that by 7.

Step-by-step explanation:

PEMDAS. Whatever is in parenthesis gets solved first, then exponents and so on and so forth.

Answer:

The integers are closed under addition, multiplication and subtraction, but NOT under division

Step-by-step explanation:

9 ÷ 2 = 4½

Step-by-step explanation:

the height from the 90° angle (which is y here) in a right-angled triangle is the square root of the Sergent lengths of the Hypotenuse.

y = sqrt(3×9) = 3×sqrt(3)

and x we get via Pythagoras :

x² = y² + 9² = 27 + 81 = 108

x = sqrt(108) = sqrt(36×3) = 6×sqrt(3)

so, A is correct.

Answer:

i think its letter B, maybe A?

Answer:

[tex]\displaystyle 7 = x[/tex]

Step-by-step explanation:

These are alternate interiour angles, and the theorem states that they are congruent, so set both expressions equivalent to each other:

[tex]\displaystyle 10x - 5 = 8x + 9 \Rightarrow \frac{-14}{-2} = \frac{-2x}{-2} \\ \\ \boxed{7 = x}[/tex]

Answer: 33

Step-by-step explanation:

Answer:

33

Step-by-step explanation:

Area of a triangle = [tex]\frac{bh}{2} \\[/tex] (base × height ÷ 2)

A = 6 · 11
       2

A = 66
      2

A = 33

Answer:

a=4

b=5

c=6

d=1

Step-by-step explanation:

7+a+b=16

2b+c=16

a+b+c+d=16

(-7,-5)

Step-by-step explanation:

3x-8y = 19

minus

3x + 5y = -46

0x - 13y = 65

- 13y = 65

÷-13

y = - 5

Substitute y = - 5 into one of the functions:

3x-8y = 19

-8 x - 5 = 40

3x + 40 =19

-40

3x. = - 21

÷3

x= - 7

Solution is (-7,-5)
