6 out of 10 is 60% so 60% percent of 43 is 25.8

The height of the tree is 25.8 feet which is casting a shadow of 43 feet long.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, A tree casts a shadow that is 43 feet long, and boy cast shadow of 10 feet who is 6 feet tall.

Assuming the height of the tree to be x.

∴ 43 : 10 : : x : 6.

43/10 = x/6.

10x = 258.

x = 25.8 feet.

So, the height of the tree is 25.8 feet.

Answer:

[tex]b_n=\dfrac{2}{3}\cdot (9)^{n-1}[/tex]

Step-by-step explanation:

Given the geometric sequence

[tex]a_1=\dfrac{2}{3}\\ \\a_n=3a_{n-1},[/tex]

then

[tex]a_1=\dfrac{2}{3}\\ \\a_2=3a_1=3\cdot \dfrac{2}{3}=2\\ \\a_3=3a_2=3\cdot 2=6\\ \\a_4=3a_3=3\cdot 6=18\\ \\a_5=3a_4=3\cdot 18=54\\ \\...[/tex]

Hence,

[tex]b_1=a_1=\dfrac{2}{3}\\ \\b_2=a_3=6=\dfrac{2}{3}\cdot 9\\ \\b_3=a_5=54=\dfrac{2}{3}\cdot 9^2\\ \\...[/tex]

Thus, the explicit formula is

[tex]b_n=\dfrac{2}{3}\cdot (9)^{n-1}[/tex]

The solution to the equation 2.4y=13.75 is found by isolating the variable y, which gives us y = 5.729167.

The question asks for the solution to the equation 2.4y =13.75. To solve this equation, we simply need to isolate the variable y. This can be done by dividing both sides of the equation by 2.4.

So, now the equation becomes y =13.75 ÷ 2.4.

After performing the division, you get y = 5.729167. Thus, y=5.729167 is the solution to the equation 2.4y=13.75.

Final answer:

To find the total number of heartbeats in an hour, multiply the heartbeats per minute by 60. For Judy, her heart beats around 4200 times in an hour.

Explanation:

Judy's heart beats 70 times a minute. To calculate how many times her heart beats in an hour, you can use the following formula:

Heartbeats per hour = Heartbeats per minute x 60 minutes

Heartbeats per hour = 70 x 60 = 4200 times

Answer: 200

Step-by-step explanation:

120 divided by 3/5 is the same thing as 120 times 5/3.

So 120 x 5 = 600

And 600 divided by 3 is 200

The result of the division 120 divided by 3/5 is : 200.

Here, we have,

given that,

What is 120 divided by 3/5

we know that,

120 divided by 3/5 is the same thing as 120 times 5/3.

i.e. 120 ÷ 3/5

=> 120 × 5/3

now, we know that,

So 120 x 5 = 600

=> 600/3

And 600 divided by 3 is 200.

so, we get,

Hence, The result of the division 120 divided by 3/5 is : 200.

Answer:

The given expression simplifies to 84x - 16y - 35

Step-by-step explanation:

The given equation is 2 ( 14x - 3y + 28x - 5y - 17.5)

The given equation simplifies to

28x - 6y + 56x - 10y  - 35

which is equal to

84x - 16y - 35

The expression 2 (14x - 3y + 28x + 12.2 - 5y - 17.5) simplifies to 84x - 16y - 10.6.

The expression that is equivalent to 2 (14x - 3y + 28x + 12.2 - 5y - 17.5) can be simplified using the distributive property and combining like terms.

First, distribute the 2 to each term inside the parentheses:

2(14x - 3y + 28x + 12.2 - 5y - 17.5) = 28x - 6y + 56x + 24.4 - 10y - 35

Next, combine like terms:

28x + 56x = 84x

-6y - 10y = -16y

24.4 - 35 = -10.6

So, the simplified expression is 84x - 16y - 10.6.

Answer:

[tex]x = - 5[/tex]

or

[tex]x = 2[/tex]

Step-by-step explanation:

We want to solve ;

[tex] {12}^{ {x}^{2} + 5x - 4} = {12}^{2x + 6} [/tex]

We equate the exponents, because is the same on both sides.

[tex] {x}^{2} + 5x - 4 = 2x + 6[/tex]

We group and rewrite in standard form to get:

[tex] {x}^{2} + 5x - 2x - 4 - 6 = 0[/tex]

[tex]{x}^{2} + 3x- 10= 0[/tex]

[tex] {x}^{2} - 2x + 5x - 10 = 0[/tex]

[tex]x(x - 2) + 5(x - 2) = 0[/tex]

[tex](x + 5)(x - 2) = 0[/tex]

[tex]x = - 5 \: or \: x = 2[/tex]

The solutions are x = 2 and x = -5.

To solve the equation [tex]12^{x^{2} +5x-4}[/tex] = [tex]12^{2x+6}[/tex], we first note that since the bases are the same, we can equate the exponents:

⇒ x² + 5x - 4 = 2x + 6.

Next, we move all terms to one side to form a quadratic equation:

⇒ x² + 5x - 4 - 2x - 6 = 0

Simplifying this gives us:

⇒ x² + 3x - 10 = 0

We can now solve this quadratic equation using the quadratic formula, which is defined as:

⇒ x = (-b ± √(b² - 4ac)) ÷ 2a

For our equation, a = 1, b = 3, and c = -10. Substituting these values into the quadratic formula:

⇒ x = (-3 ± √(3² - 4 × 1 × (-10))) ÷2 × 1

⇒ x = (-3 ± √(9 + 40)) ÷ 2

⇒ x = (-3 ± √49) ÷ 2

⇒ x = (-3 ± 7) ÷ 2

This gives us two solutions:

⇒ x = (4) ÷ 2 = 2

⇒ x = (-10) ÷ 2 = -5

So, the solutions are x = 2 and x = -5.
