aleksandrvk [35]

Answer:

14.6

Step-by-step explanation:

The computation of average price paid for the share is shown below:-

Average = \frac{Total\ investment}{Total\ share}

= \frac{6,000}{410}

= 14.6

For more clarification please find the attachment as attached using excel spreadsheet.

By dividing the total investment by the total number of shares we can get the average price paid for the share and the same is to be considered

Moreover, the total investment and the total shares are shown in the attachment. Kindly find it below:

One month Pablo rented 12 movies and 2 video games for a total of $65. The next month he rented 3 movies and 5 video games for a
borishaifa [10]

The rent for one movie is $4.50 and rent for one video game is $5.50

Step-by-step explanation:

Let,

Rent for one movie = x

Rent for one video game = y

According to given statement;

12x+2y=65     Eqn 1

3x+5y=41        Eqn 2

Multiplying Eqn 2 by 4

4(3x+5y=41)\\12x+20y=164\ \ \ \ Eqn\ 3

Subtracting Eqn 1 from Eqn 3

(12x+20y)-(12x+2y)=164-65\\12x+20y-12x-2y=99\\18y=99\\

Dividing both sides by 18

\frac{18y}{18}=\frac{99}{18}\\y=5.50

Putting y=5.50 in Eqn 2

3x+5(5.50)=41\\3x+27.50=41\\3x=41-27.50\\3x=13.50

Dividing both sides by 3

\frac{3x}{3}=\frac{13.50}{3}\\x=4.50

The rent for one movie is $4.50 and rent for one video game is $5.50

If ABC is an isosceles triangle and DBE is an equilateral triangle find each missing measure
sineoko [7]

Answer:

∠1=∠9=43°,  ∠2=∠7= 17°,  ∠4=∠5=∠6=60°, ∠3=∠8=120°

Step-by-step explanation:

Given ABC is an isosceles triangle and DBE is an equilateral triangle. we have to find each missing measure.

In triangle ABC,

∠1=∠9    (∵isosceles triangle)

⇒ 4x+3=9x-47

⇒ 9x-4x=3+47 ⇒ 5x=50 ⇒ x=10

Hence, ∠9=∠1=(4x+3)°=4(10)+3=43°

Also, given ΔBDE is an equilateral triangle, and all angle of equilateral triangle are equal.

∴ ∠4+∠5+∠6=180°

⇒ ∠4+∠4+∠4=180° ⇒ 3∠4 = 180° ⇒ ∠4 = 60°

∴ ∠4=∠5=∠6=60°

By exterior angle property, ∠3=∠5+∠6=60°+60°=120°

                                             ∠8=∠5+∠4=60°+60°=120°

In ΔABD, ∠1+∠2+∠3=180°

             ⇒ 43°+120°+∠2=180°⇒ ∠2 = 17°

In ΔABD, ∠9+∠8+∠7=180°

             ⇒ 43°+120°+∠7=180°⇒ ∠7= 17°

The perimeter of a rectangle is 72 in. The base is 3 times the height. Find the area of the rectangle
Dovator [93]

Answer:

243 in²

Step-by-step explanation:

Step 1. Calculate the<em> base and height </em>of the rectangle

We have two conditions:

(1)   2b+ 2h = 72 in

(2)           b = 3h               Substitute in (1)

2(3h) + 2h = 72               Remove parentheses

   6h + 2h = 72               Combine like terms

           8h = 72               Divide by 6

             h = 9 in             Substitute in(2)

             b = 3 × 9

             b = 27 in

Step 2. Calculate the area of the rectangle

A = bh

A = 27 × 9

A = 243 in²

The area of the rectangle is 243 in².

Is 1212 a prime number?
brilliants [131]
No. it is not a prime number.

a prime number is a number greater than 1 that is only divisible by 1 and itself. Example of a prime number is 2.

2 / 2 = 1 or  2/ 1 = 2.

1212 can be divided by 2, 3, 4, 6,.... It is not a prime number. Instead it is recognized as a composite number.
