Answer:

₹[tex]9,600[/tex]

Step-by-step explanation:

we know that

The simple interest formula is equal to

[tex]I=P(rt)[/tex]

where

I is the amount interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

[tex]t=4.5\ years\\ P=?\\ I=1,512\\r=0.035[/tex]

substitute in the formula above

[tex]1,512=P(0.035*4.5)[/tex]

[tex]P=1,512/(0.035*4.5)=9,600[/tex]

Answer:

156.25% increase (56.25% added)

Step-by-step explanation:

Area formula of circle: A = πr²

1. Area when rope = 20 ft:

Plug in: A = π(20)²

Multiply: A = 400π ft²

2. Area when rope = 25 ft:

Plug in: A = π(25)²

Multiply: A = 625 ft²

3. Percent increase:

Increase compared to original: 625/400 = 1.5625 = 156.25%

Answer:

56.25%

Step-by-step explanation:

We are given that a horse is tethered on a 20 ft rope. If the rope is lengthened to 25 ft, we are to percentage by which its grazing area increases.

Grazing area with 20 ft rope = [tex]\pi \times 20^2[/tex] = [tex]400\pi[/tex]

Grazing area with 25 ft rope = [tex]\pi \times 25^2[/tex] = [tex]625\pi[/tex]

Percentage by which area increases = [tex] \frac { 6 2 5 \pi - 400 \pi } { 400 \pi } \times 100 [/tex] = 56.25%

Answer:

∴The distance CA =  = 2√2

Step-by-step explanation:

Find the distance CA:

The distance between two points (x₁,y₁),(x₂,y₂) = d

The coordinates of point C = (-2,2)

The coordinates of point A = (0,0)

The distance CA distance between C and A

∴The distance CA =  = 2√2

The distance[tex]\( C'B' \) is \( \sqrt{10} \)[/tex] units.

after applying the transformation[tex]\( T: (x, y) \rightarrow (x + 2, y + 1) \)[/tex], the distance between points [tex]\( C' \)[/tex] and [tex]\( B' \)[/tex] is [tex]\( \sqrt{10} \)[/tex] units.

The distance [tex]\( C'B' \)[/tex] is [tex]\( \sqrt{10} \)[/tex] units.

To find the distance [tex]\( C'B' \)[/tex], we first need to find the coordinates of points [tex]\( C' \)[/tex] and [tex]\( B' \)[/tex] after applying the transformation [tex]\( T: (x, y) \rightarrow (x + 2, y + 1) \) to points \( C \)[/tex] and [tex]\( B \).[/tex]

Given the coordinates of [tex]\( C \)[/tex] and [tex]\( B \)[/tex] as[tex]\( C(1, 2) \)[/tex] and [tex]\( B(4, 3) \)[/tex] respectively, we apply the transformation to each point:

For point [tex]\( C \):[/tex]

[tex]\[ C'(x', y') = (x + 2, y + 1) = (1 + 2, 2 + 1) = (3, 3) \][/tex]

For point [tex]\( B \):[/tex]

[tex]\[ B'(x', y') = (x + 2, y + 1) = (4 + 2, 3 + 1) = (6, 4) \][/tex]

Now, we use the distance formula to find the distance between [tex]\( C' \)[/tex]and [tex]\( B' \):[/tex]

[tex]\[ C'B' = \sqrt{(x'_2 - x'_1)^2 + (y'_2 - y'_1)^2} \][/tex]

[tex]\[ C'B' = \sqrt{(6 - 3)^2 + (4 - 3)^2} \][/tex]

[tex]\[ C'B' = \sqrt{(3)^2 + (1)^2} \][/tex]

[tex]\[ C'B' = \sqrt{9 + 1} \][/tex]

[tex]\[ C'B' = \sqrt{10} \][/tex]

Thus, the distance [tex]\( C'B' \)[/tex] is[tex]\( \sqrt{10} \)[/tex] units.

In conclusion, after applying the transformation [tex]\( T: (x, y) \rightarrow (x + 2, y + 1) \)[/tex], the distance between points [tex]\( C' \)[/tex] and [tex]\( B' \)[/tex] is [tex]\( \sqrt{10} \)[/tex] units.

Answer:

D. [tex](x-2y)(x-y)(x+y)[/tex]

Step-by-step explanation:

In the polynomial [tex]x^3-2x^2y-xy^2+2y^3[/tex] group first two terms and second two terms:

[tex](x^3-2x^2y)+(-xy^2+2y^3)[/tex]

First two terms have common factor [tex]x^2[/tex] and last two terms have common factor [tex]y^2,[/tex] hence

[tex](x^3-2x^2y)+(-xy^2+2y^3)=x^2(x-2y)+y^2(-x+2y)[/tex]

In brackets you can see similar expressions that differ by sign, so

[tex]x^2(x-2y)+y^2(-x+2y)=x^2(x-2y)-y^2(x-2y)=(x-2y)(x^2-y^2)[/tex]

Now use formula

[tex]a^2-b^2=(a-b)(a+b)[/tex]

You get

[tex](x-2y)(x^2-y^2)=(x-2y)(x-y)(x+y)[/tex]

Let

z----> the scale factor

x----> volume of the larger solid

y----> volume of the smaller solid

[tex]z^{3}=\frac{x}{y}[/tex]

we have

[tex]x=125\ in^{3}[/tex]

[tex]y=27\ in^{3}[/tex]

substitute

[tex]z^{3}=\frac{125}{27}[/tex]

[tex]z=\frac{5}{3}[/tex]

step 2

Find the surface area of the larger solid

we know that

If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared

Let

z----> the scale factor

x----> surface area of the larger solid

y----> surface area of the smaller solid

[tex]z^{2}=\frac{x}{y}[/tex]

we have

[tex]z=\frac{5}{3}[/tex]

[tex]y=63\ in^{2}[/tex]

substitute

[tex](\frac{5}{3})^{2}=\frac{x}{63}[/tex]

[tex]x=\frac{25}{9}*63=175\ in^{2}[/tex]

After giving 93 centimeters (which is 0.93 meters) of his 214 meters of rope to his brother, Ravi has 213.07 meters of rope left.

This question involves the concept of subtraction in the measurement unit of meters and centimeters. Initially, Ravi has 214 meters of rope. If he gives 93 centimeters of rope to his brother, keep in mind that 1 meter equals 100 centimeters. So, 93 centimeters is equal to 0.93 meters.

So, to find out how much rope Ravi is left with, you subtract the amount he gave to his brother from the original amount he had: 214 meters - 0.93 meters = 213.07 meters. This is the amount of rope Ravi has left after giving some to his brother.

Answer:

It will be 2 feet and 9.6 inches wide

Step-by-step explanation:

First you divide 24 inches(2 feet) by 5 inches to find out the rate unit rate of change. Your answer would be 4.8. Then you multiply 4.8 by 7 to figure out how wide it would be, which gives you 33.6 inches(or 2 feet and 9.6 inches)

To solve the equation[tex]\(x^2 = 50\),[/tex] we'll take the square root of both sides. However, when we do this, we need to consider both the positive and negative square roots:

[tex]\[ x = \pm \sqrt{50} \]\[ x = \pm \sqrt{25 \cdot 2} \]\[ x = \pm 5\sqrt{2} \]So, the solutions to the equation \(x^2 = 50\) are \(x = 5\sqrt{2}\) and \(x = -5\sqrt{2}\).[/tex]

To solve the equation [tex]\(x^2 = 50\),[/tex]we'll take the square root of both sides. Remembering that the square root of a number has both positive and negative solutions, we have:

[tex]\[ x = \pm \sqrt{50} \]\[ x = \pm \sqrt{25 \cdot 2} \]\[ x = \pm 5\sqrt{2} \][/tex]

Therefore, the solutions to the equation[tex]\(x^2 = 50\) are \(x = 5\sqrt{2}\) and \(x = -5\sqrt{2}\). This means that when \(x\) is equal to either \(5\sqrt{2}\) or \(-5\sqrt{2}\), \(x^2\) will be equal to 50. These solutions represent the values of \(x\)[/tex]that satisfy the original equation and make it true.

Step-by-step explanation:

(5+12)×6×14-(5÷2)²π×14

Answer:

Part A)  Is a directly proportional

Part B) The constant of proportionality is [tex]k=0.25[/tex]

Part C) The equation is [tex]y=0.25x[/tex]

Part D) [tex]62.5[/tex]  acres of soybeans

Step-by-step explanation:

Part A) Are the number of acres of corn and the number of acres of soybeans directly proportional or inversely proportional?

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex]

Let

x-----> the number of acres of corn

y---->  the number of acres of soybeans

so

[tex]y/x=k[/tex]  

if the number of acres of corn increases then the number of acres of soybeans increases

if the number of acres of corn decreases then the number of acres of soybeans decreases

therefore

The relationship is a directly proportional

Part B) What is the constant of proportionality?

we have that

For x=200, y=50

substitute

[tex]y/x=k[/tex]

[tex]k=50/200[/tex]

[tex]k=0.25[/tex]

Part C) Let x equal the number of acres of corn and y equal the number of acres of soybeans. Write an equation to show this relationship.

The linear equation that represent the direct variation is equal to

[tex]y/x=k[/tex]

we have

[tex]k=0.25[/tex]

substitute

[tex]y/x=0.25[/tex]

[tex]y=0.25x[/tex]

Part D) How many acres of soybeans can the farmer plant this year if he plants 250 acres of corn?

For x=250

Find the value of y

substitute in the linear equation the value of x and solve for y

[tex]y=0.25(250)=62.5[/tex] -----> acres of soybeans

I'll do both.

[tex]

5x-97>-34\Rightarrow x>\frac{-34+97}{5}=\frac{63}{5}=\boxed{12.6} \\

so, using that exponential model, the 1st output value works, but the second value of 2² does not give us 8 as output.

[tex]\bf slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{8-2}{2-1}\implies \cfrac{6}{1}\implies 6 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-2=6(x-1) \\\\\\ y-2=6x-6\implies y=6x-4[/tex]

now, using that model, x = 6, then y = 6(6) - 4, or y = 32.

Answer:

(b, c)

Step-by-step explanation:

The mid-point of two vertices or point is calculated by adding the respective coordinates of those points and then dividing by two. The x-coordinates will be added and then divided by 2 and then y-coordinates will be added and divided by 2.

So for the given question,

P(0,0)

Q(2a,0)

And

R(2b, 2c)

Mid-point of PR =( (0+2b)/2, (0+2c)/2)

=(2b/2, 2c/2)

=(b,c)

So the mid-point of PR is (b, c)

Answer:

Mindy uses more white beads

Step-by-step explanation:

For Mindy:

red : white = 4 : 5 = 12 : 15

For Daisy:

red : white = 6 : 7 = 12 : 14

When both use 12 red beads, Mindy uses 15 white beads and Daisy uses 14 white beads.

Mindy uses more white beads when both use 12 red beads.

When they each use 12 red beads, Mindy uses more white beads in her necklaces as per the given ratios. Mindy uses 15 white beads, while Daisy uses 14 white beads.

Mindy uses a ratio of 4 red beads to 5 white beads, and Daisy uses a ratio of 6 red beads to 7 white beads. If they each use 12 red beads, we can equate their ratios. For Mindy, the equivalent ratio would be 12 red beads to 15 white beads because 4 red beads go into 12 red beads three times and three times 5 gives 15 white beads. For Daisy, the equivalent ratio would be 12 red beads to 14 white beads as 6 red beads go into 12 red beads twice and twice 7 gives 14. Therefore, when they each use 12 red beads, Mindy uses more white beads in her necklaces using beads.

Step-by-step explanation:

1. 10000cm^3/25cm= 400cm^2

2. 400cm^2/10 cm= 40cm

Final answer:

To find the height of the box, divide the volume of the box by the area of the base. In this case, the height is 40 cm.

Explanation:

To find the height of the box, we need to divide the volume of the box by the area of the base. The volume is given as 10000 cm³ and the base has dimensions 25 cm by 10 cm. So, the area of the base is 25 cm * 10 cm = 250 cm². Now, we can find the height by dividing the volume by the area: Height = Volume / Area = 10000 cm³ / 250 cm² = 40 cm.
