A geometrical series have a constant ratio. The value of r is 4, while the value of a1 is 0.25 and the value of n is 5.

A geometrical series is a series of numbers where the quotient of any two consecutive terms of the series is constant.

The given series is a geometrical series which is given as, 0.25, 1, 4, 16, 64.

Now the value of r is the ratio of any two consecutive terms of the geometrical series therefore, the value of r can be written as,

[tex]r = \dfrac{1}{0.25}=4[/tex]

The a1 of a geometrical series is the first term of the series, therefore, the value of a1 can be written as,

a1 = 0.25

The n is the number of terms in a geometrical series, therefore, the value of n can be written as

n = 5

Hence, the value of r is 4, while the value of a1 is 0.25 and the value of n is 5.

Answer: 4 yd, 130 in, 10ft

Step-by-step explanation:

So first you turn everything into inches

130 inches is already in inches.

4 yards = 12 ft

1ft = 12 in

12 *12 = 144 in

so 4 yards is 144 inches

10 ft = 12*10

12*10 = 120

so 10ft is 120 inches

144 inches is the greatest and 120 inches is the least.

Step-by-step explanation:

Answer:

what will be the price of the next model= 59,748

Step-by-step explanation:

7748 is 14.9% of 52000

Solution:

What is 14.9% of 52000?

Y is 14.9% of 52000

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 14.9% * 52000

Converting percent to decimal:

p = 14.9%/100 = 0.149

Y = 0.149 * 52000

Y = 7748

To find the price for the next model

7748 + 52000

=> 59,748

The expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.

The measure of the boundary of the sides of a square is called its perimeter. The perimeter of a square is 4 times the side of the square.

[tex]P=4a[/tex]

Here, (a) is the side of the square.

A square has a perimeter of 12x +52 units. The perimeter of a square is 4 times the side of the square. Thus, the side of this square is,

[tex]P=4a\\12x +52=4a\\a=\dfrac{12x +52}{4}\\a=\dfrac{4(3x +12)}{4}\\a=3x+12[/tex]

Thus, the expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.

y = -13/16

Step-by-step explanation:

Given:

0.8y+0.25= -0.4

To Find:

Solve for y

Solution:

Multiply both sides by 100

[tex]0.8y\cdot \:100+0.25\cdot \:100=-0.4\cdot \:100[/tex]

Simplify

[tex]80y+25=-40[/tex]

Subtract 25 from both sides

[tex]80y+25-25=-40-25[/tex]

Simplify

[tex]80y=-65[/tex]

Divide both sides by 80

[tex]\frac{80y}{80}=\frac{-65}{80}[/tex]

Answer:

  214°

Step-by-step explanation:

The external angle (marked 34°) is equal to half the difference of the arcs ACB and AB.

  34° = 1/2(ACB -AB)

Together, the two arcs form a complete circle of 360°, so we have ...

  34° = 1/2(ACB -(360° -ACB)) = 1/2(2ACB -360°)

  34° = ACB -180° . . . . . . . . . . . . simplify

  180° +34° = ACB = 214° . . . . . add 180°

The measure of arc ACB is 214°.
