Answer:

After 15 years the population will be 7,625

Step-by-step explanation:

3.5% of 5,000 = 175

175 x 15 = 2625

2625 + 5,000 = 7625

The population after 15 years should be  8,376

Since the population is 5,000 and it grows 3.5 years and the time period is 15 years

So, the population after 15 years is

[tex]= 5,000 \times (1 + 3.5\%)^{15}\\\\[/tex]

= 8,376

Therefore, we can conclude that The population after 15 years should be  8,376

Answer:

527

Step-by-step explanation:

237.15/0.45 = 527

Answer:

They sold 527 toys.

Step-by-step explanation:

If they make 0.45$ profit on every toy.

Total profit of a month is $237.15.

then no of toys sold = total profit divided by individual profit

Number of toys= 237.15/0.45 =527

Answer:

1. 48 + 86 + + Q = 180

2. 46 degrees

3. They are congruent

Step-by-step explanation:

I just got them right on edg

Angle sum property (In ΔPQR, ∠P + ∠Q + ∠R = 180°) can be used to determine the measure of angle Q.

Using angle sum property, ∠Y = 46°.

It can be concluded that ∠Y = ∠Q.

The angle sum property of a triangle states that the sum of the angles of a triangle is equal to 180º.

In ΔPQR,

∠P + ∠Q + ∠R = 180° (angle sum property)

86 + ∠Q + 48 = 180

∠Q = 180 - 86 - 48 = 46°

In ΔXYZ,

∠X + ∠Y + ∠Z = 180° (angle sum property)

86 + ∠Y + 48 = 180

∠Y = 180 - 86 - 48 = 46°

As visible, ∠Q = ∠Y.

Range: 9.4

Step-by-step explanation:

arrange the following data set from least to greatest.

1.6, 3, 4, 4, 7, 9, 9, 10, 11

Mean: Finding the total average of the following data set.

Median: The middle number in the data set

Range: Subtracting the highest and the lowest value from the arranged data set.

Mean: 1.6 + 3 + 4 + 4 + 7 + 9 + 9 + 10 + 11 = 58.6/9 = 6.5

Step-by-step explanation: because when you draw it out on a coordinate plain (-1,5) lies right in the middle of these two points.

The square root of 18 is 4.2426, rounded down to the closest whole number is 4. Testing the integer values 1 through 4 for division into 18 with a 0 remainder we get these factor pairs: (1 and 18), (2 and 9), (3 and 6). The factors of 18 are 1, 2, 3, 6, 9, 18.

Answer:

x ≈ - 2.5; Option D

Step-by-step explanation:

Let us substitute f ( x ) with 0, as to find the " real zero " of the function;

0 = x^2 - 4x + 6, ⇒ Now find one solution for x^2 - 4x + 6 = 0, using Newton - Raphson, provided it applies an iterative process to approach one root of a function, ( x( n + 1 ) = x( n ) - ( f( x( n ) ) )/( f '( x( n ) ) ) ),

d / dx * ( x^3 - 4x + 6 ), ⇒ Apply sum / difference rule ( f ± g ) ' = f ' ± g, '

d / dx * ( x^3 ) - d / dx * ( 4x ) + d / dx * ( 6 ), ⇒ Simplify,

3x^2 - 4 + 0, 3x^2 - 4, ⇒ Compute x( n + 1 ) until Δ x( n + 1 ) < 0.000001,

x ≈ - 2.52510.....

Answer; x ≈ - 2.5; Option D

Answer:

x=6

Step-by-step explanation:

The area of a triangle is given by

A = 1/2 bh

44 = 1/2 (2x-4)(x+5)

Multiply the 1/2 time (2x-4)

44 = (x-2) (x+5)

FOIL

44 = x^2 +5x -2x-10

Combine like terms

44 = x^2 +3x -10

Subtract 44 from each side

0 = x^2 +3x -10-44

0 = x^2 +3x -54

Factor

What two numbers multiply to -54 and add to 3

9*-6 = -54

9+-6 = -3

0 = (x+9)(x-6)

Using the zero product property

x +9 =0    x-6 =0

x = -9          x = 6

The height cannot be negative so x cannot be -9

x=6

Answer:

[tex] V = \pi r^2 h[/tex]

And for this case the value for the height is [tex] h = 10.7 in[/tex] the diameter is provided [tex] D = 2r = 8.1 in[/tex] so then the radius is given by:

[tex] r = \frac{D}{2}=\frac{8.1 in}{2}= 4.05 in[/tex]

Then we can find the volume with the first formula and replacing we got:

[tex] V = \pi (4.05in)^2 (10.7 in)= 551.4 in ^3[/tex]

The final answer for this case would be 551.4 cubic inches

Answer:

5000pi ft^3 (exactly) or 15,708 ft^3 (approximately)

Step-by-step explanation:

V = (pi)r^2h

r = radius = diameter/2

r = 20 ft/2 = 10 ft

V = (pi)(10 ft)^2(50 ft)

V = 5000(pi) ft^3

V = 5000(3.14159) ft^3 = 15,708 ft^3

Answer:

42.1 cm

Step-by-step explanation:

The length of the arc is circumference of the circle - length of minor arc GH

circumference of circle = 2 * π * r = 2 * π * 9.1 = 18.2 π cm

The length of the minor arc = angle/360 * 2 * π * r

Now this is tricky, the angle is 360-265 = 95

The length of the minor arc = 95/360 * 2 * π * 9.1 = 4.80 π

Length of major arc = 18.2 π -4.8 π = 13.4 * π = 13.4 * 22/7 = 42.11cm
