What’s the area of the triangle & parallelogram

Answer: r = 1.69 inches

              h = 2.15 inches

Step-by-step explanation: Volume of a solid is the amount of space contained within a solid.

Volume of a cone is directly proportional to radius and height:

[tex]V=\frac{1}{3}\pi r^{2}h[/tex]

They want the cones to hold the same volume of 9 cubic inches.

If height is 3:

[tex]9=\frac{1}{3}\pi r^{2}3[/tex]

[tex]\pi r^{2}=9[/tex]

[tex]r^{2}=2.864[/tex]

r = 1.69 inches

When height is 3, radius is 1.69 inches for a cone to have 9 cubic inches of volume.

If radius is 2:

[tex]9=\frac{1}{3}\pi (2)^{2}h[/tex]

[tex]h=\frac{9(3)}{4 \pi}[/tex]

h = 2.15 inches

If radius is 2 inches, height of the cone is 2.15 inches.

The correct equation for the triangle is,

⇒ DF ≅ FD

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

By the figure, the coordinate of triangles are,

D = (- 5, 1)

E = (- 2, 3)

F = (- 3, - 2)

Hence, By using distance formula;

DE = √ (- 5 + 2)² + (1 - 3)²

     = √9 + 4

     = √13

EF = √ (- 2 + 3)² + (3 + 2)²

     = √1 + 25

     = √26

FD = √ (- 5 + 3)² + (1 + 2)²

     = √4 + 9

     = √13

Thus, We have;

⇒ DF ≅ FD

Answer:

Raheem

Step-by-step explanation:

Josh :

using simple interest formula :

Final amount = P(1 + rt)

Final amount = 1200(1 + 0.04*5)

Final amount = 1200(1.2)

Final amount = £1440

Raheem :

Using compound interest formula :

Final amount = P(1 + r/n)^nt

Final amount = 1250(1 + 0.03)^5

Final amount = 1250(1.03)^5

Final amount = £1449.09

Answer:

approximately 17.3 years

Step-by-step explanation:

Compound interest is the interest we earned on the interest.

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + r/n)^{nt}[/tex]

The formula used to find continuously compounded is:

t = log (A/P) / r

The time it will take to double her money is 17.329 years.

It is the interest we earned on the interest.

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + r/n)^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

We have,

P = $5,000

r = 4%

Amount = 2 x 5000 = $10,000

n = infinite number of times.

Now,

Solve the equation for t

The formula used to find for continuously compounded is:

t = log (A/P) / r

t = log (10,000.00/5,000.00) / 0.04

t = 17.329 years

Thus,

The time it will take to double her money is 17.329 years.

Responder:

(x + 2) ² + (y-4) ² = 100

Explicación paso a paso:

La ecuación de un círculo se expresa como (x-x0) ² + (y-y0) ² = r²

r es el radio

(x0, y0) es el centro

Dado que el centro representa el punto medio de (-7, -6) y (3,14)

x0 = -7 + 3/2

x0 = -4/2

x0 = -2

y0 = -6 + 14/2

y0 = 8/2

y0 = 4

Sustituir en la expresión

(x - (- 2)) ² + (y-4) ² = 10²

(x + 2) ² + (y-4) ² = 100

Por lo tanto, la ecuación requerida del círculo es (x + 2) ² + (y-4) ² = 100

Answer:

D: x ≥ -2

Step-by-step explanation:

The arrow points to the right on the number line, meaning the inequality uses the greater than sign.

The solid point at -2 means that -2 is included in the solution for x.

So, the final inequality is x ≥ -2.

Answer:

X< - 1

Step-by-step explanation:

Answer:

x= 1

y= -2

Step-by-step explanation:

equation (1): y= -3x+1

equation (2): y=x-3

solve the system of equations by substitution:

step1: sub ( x-3 ) for y in equation 1:

y = -3x+1

x-3 = -3x+1

step2: simplify the equation to get x:

(add 3 for both sides)

x = -3x+4

(add 3x for both sides)

4x = 4

(divide 4 from both sides)

x = 1

step3: sub the value of x (x=1) in equation 2:

y = x-3

y = 1-3

step4: solve the equation to get y:

y = -2

The solution is 32 1/3 , 33 1/3 and 34 1/3

The three consecutive numbers which have a sum of 100 is given by the equation A = 32 1/3 + 33 1/3 + 34 1/3

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first number be = n

Let the second number be = n + 1

Let the third number be = n + 2

So , the sum of all the three consecutive numbers is 100

Substituting the values in the equation , we get

n + ( n + 1 ) + ( n + 2 ) = 100   be equation (1)

On simplifying the equation , we get

3n + 3 = 100

Subtracting 3 on both sides of the equation , we get

3n = 97

Divide by 3 on both sides of the equation , we get

n = 32 1/3

So , the first number n = 32 1/3

Second number = n + 1 = 33 1/3

Third number = n + 2 = 34 1/3

Therefore , A = 32 1/3 + 33 1/3 + 34 1/3 = 100

Hence , The three consecutive numbers which have a sum of 100 is given by the equation A = 32 1/3 + 33 1/3 + 34 1/3
