Finding a₁₂

Answer:

[tex]a_{12}=106[/tex]

Step-by-step explanation:

Arithmetic sequence

General form of an arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]

where:

Given:

To find the common difference (d), substitute the given values into the general formula and solve:

[tex]\begin{aligned}\implies a_6=(-4)+(6-1)d & =46\\ 5d-4 & =46\\ 5d & = 50\\ d & =10\end{aligned}[/tex]

Therefore, the equation for the nth term is:

[tex]\begin{aligned}a_n &=-4+(n-1)10\\& =10n-14 \end{aligned}[/tex]

To find the 12th term, substitute n = 12 into the equation:

[tex]\implies a_{12}=10(12)-14=106[/tex]

Step-by-step explanation:

Answer:

70/100 ; 3/10 ; 50/100

Step-by-step explanation:

You need to multiply numbers to make them equivalent.

1st Question:

7/10 has to multiply by 10/10 because the denominator of the other one is 100 and 10 x 10 is 100.

7 x 10 = 70

70/100 shall be your answer.

2nd Question:

This time you need to find your starting point.

A way to do this is to divide/simplify the fraction in order to make it equivalent.

You need to divide by 10 because your quotient and denominator at your starting point is 10 and 100/10 is 10.

30 divided by 10 is 3

Your Answer for this one is: 3/10

3rd Question:

Same thing as the 1st one.

Multiply by 10.

5 x 10 = 50

50/100 is your answer.

Check the picture below, recall that the radius of a circle is always the same length in the circle.

-50 is your answer it is really easy just try to get -50

Answer:

x ≤ 2

Step-by-step explanation:

4.5 = medium ice cream

0.75x = toppings, x = amount of toppings

Sophia has $6.4, so 4.5+0.75x has to be less or equal to that.

4.5 + 0.75x ≤ 6.4, solve

0.75x ≤ 1.9

x ≤ 2 8/15

BUT you cannot get half a topping or a fraction of a topping,

so, x ≤ 2 toppings.

Sophia can get 2 or less toppings.

Step-by-step explanation:

Finding the price that maximizes profit requires several steps. We need the demand function that tells quantity sold in terms of selling price. With this, we can express the cost and revenue functions in terms of selling price. The profit will be the difference between revenue and cost.

__

The demand (q) is said to be a linear function of price (p). The equation for that can be written ...

  q(p) = (q2 -q1)/(p2 -p1)(p -p1) +q1 . . . . . for two points (p1, q1) and (p2, q2)

Using the given demand points, this can be ...

  q(p) = (1900 -2600)/(575 -470)(p -470) +2600

  q(p) = -20/3(p -470) +2600

  q(p) = -20/3p +5733 1/3

__

The cost function in terms of selling price can be found by substituting the q(p) equation for x in c(x). For the purpose of finding the maximum profit, we only need the marginal cost function:

  c(q(p))' = c'(q(p))·q'(p) = (608 -0.18(q(p)))·(-20/3) = (608 -0.18(-20/3p +5733 1/3))(-20/3)

  c'(p) = -8p +2826 2/3

__

As with cost, the function we need for finding the maximum profit is the marginal revenue function. Revenue is the product of price and demand, so the marginal revenue is ...

  r(p) = p·q(p)

  r'(p) = q(p) +p·q'(p) = (-20/3p +5733 1/3) +p(-20/3)

  r'(p) = -40/3p +5733 1/3

__

The maximum profit is found where the marginal profit is zero. In turn, that is found where the difference between marginal revenue and marginal cost is zero:

  P = R -C

  P'(p) = 0 = r'(p) -c'(p) = (-40/3p +5733 1/3) -(-8p +2826 2/3)

  0 = -16/3p +2906 2/3

  16p = 8720 . . . . . multiply by 3, add 16p

  p = 545 . . . . . . . price for maximum profit

The price per set that maximizes profit is $545.00.

Hey there!

41/40 - 3/8

= 41/40 - 3 × 5 / 8 × 5

= 41/40 - 15/40

= 41 - 15 / 40 - 0

= 26 / 40

= 26 ÷ 2 / 40 ÷ 2

= 13 / 20

Therefore, your answer is: 13/20

Natalie Albert deposited checks totaling $1,735,97 into her savings account, she withdrew $100.00 while depositing some coins. If her total deposit was $1,668.71 then Natalie deposited $32.74 in coins.

Two or more expressions with an Equal sign is called as Equation.

Let's call the amount Natalie deposited in coins "x".

We know that her total deposit was $1,668.71,

so we can write an equation:

1,735.97 - 100.00 + x = 1,668.71

Simplifying, we get:

1,635.97 + x = 1,668.71

Subtracting 1,635.97 from both sides, we get:

x = 32.74

Therefore, Natalie deposited $32.74 in coins.

The area of the property is the product of its dimensions, and the expression for the area is (x + 10)²

The area of the land is the product of its dimensions.

Let the length and the width of the land be x.

So, the area measured by the appraisal is:

Area = x²

One side of the land is 10 more than the measured length.

So, we have:

Area = (x + 10)²

Substitute 12 for x

Area = (12 + 10)²

Evaluate

Area = 484

Hence, the area of the property is 484

To write the equation in slope-intercept form

  ⇒ must know what is the slope-intercept form

       ⇒ [tex]y = mx + b[/tex]

Let's find the slope first:

   ⇒ must know the slope's formula

       ⇒ [tex]\frac{y2-y1}{x2-x1}[/tex]

          ⇒ [tex]\frac{0-1}{-3-0}=\frac{-1}{-3} =\frac{1}{3}[/tex]

Now let's find the y-intercept

  ⇒ which occurs where the x-value of the coordinate is 0

    ⇒ that point is (0,1)

       ⇒ thus b = 1

Now let's set up the equation in slope-intercept form

The percentage of households that were not watching the show were 46.81%.

In this case, we need to find the percentage of households that don´t watch the show. First, we need to know how much households don´t watch the show, this is:

[tex]94,000,000-50,000,000=44,000,000[/tex]

So, the households that were not watching the show were 44 million.

Now we can calculate the percentage, to find a percentage we use a division and to introduce the percentage units we multiply by 100.

The percentage of households that were not watching the show were 46.81%.
