If the nth term of a number sequence is 4n^2+ n find the first 3 terms and 10th term
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

Miguel spent $11 to buy 16 apples and oranges. How many of each type of fruit did he buy F apples cost $0. 75 and oranges cost $0. 65
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

Soo, I need help with these 3 math problems. I don't have enough time to do them before I go to bed.
So these apple pies have a ratio of 15 apples to 3 pies. How many apples do you need for 12 pies?
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

The girl’s hockey team won 6 games, lost 3 games, and tied 2 games. What fraction of games did they win?
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
solve for x and y.
A.
B.
C.
D.
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.

Find the value of X for the given parallelogram
Answer:
15[tex] \: [/tex]
Step-by-step explanation:
Parallelogram is a quadrilateral whose both pairs of opposite sides are parallel and equal and opposite angles are also equal.
[tex] \: [/tex]
So,
[tex] \\ { \longrightarrow \qquad{ \pmb{ \sf { \angle P = \angle R}}}} \: \: \\ \\[/tex]
[tex]{ \longrightarrow \qquad{ \pmb{ \sf { 6x - 10 = 2x + 50}}}} \: \: \\ \\[/tex]
Subtracting 2x from both sides we get :
[tex] \\ { \longrightarrow \qquad{ \pmb{ \sf { 6x - 10 - 2x = 2x + 50 - 2x}}}} \: \: \\ \\[/tex]
[tex]{ \longrightarrow \qquad{ \pmb{ \sf { 4x - 10 = 50 }}}} \: \: \\ \\[/tex]
Adding 10 to both sides we get :
[tex] \\ { \longrightarrow \qquad{ \pmb{ \sf { 4x - 10 + 10 = 50 + 10 }}}} \: \: \\ \\[/tex]
[tex]{ \longrightarrow \qquad{ \pmb{ \sf { 4x = 60 }}}} \: \: \\ \\[/tex]
Dividing 4 from both sides we get :
[tex]{ \longrightarrow \qquad{ \pmb{ \sf { \frac{4x}{4} = \frac{60}{4} }}}} \: \: \\ \\[/tex]
[tex]{ \longrightarrow \qquad{ \pmb{ \frak { x = 15 }}}} \: \: \\ \\[/tex]

Solve the inequality.
r+0.2<−0.7
Answer:
r<−0.9
Step-by-step explanation:
Let's solve your inequality step-by-step.
r+0.2<−0.7

Which operation should you perform first in the expression 7 × 2 by the power of 3
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.
Find the solution of the system of equations. 3x-8y = 19
3x + 5y = -46
(-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)

Solve by completing the square.
w2 – 16w – 19 = 0
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

There is a bag with only red marbles and blue marbles.
The probability of randomly choosing a red marble is
7
8
.
There are 56 marbles in total in the bag and each is equally likely to be chosen.
Work out how many red marbles there must be.
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.

[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]
