2/3 and 3/2

Step-by-step explanation:

→ Divide the smaller triangle by the larger one for the first one

8 ÷ 12 = 8/12 = 2/3

→ Divide the larger triangle by the smaller one for the second one

12 ÷ 8 = 12/8 = 3/2

Based on table shown above, we have that: B. No, because one x-value corresponds to two different y-values.

A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables. This ultimately implies that, a function is typically used for mapping an input variable to an output variable.

Based on table shown above, we can reasonably infer and logically deduce that this table does not represent a function because one x-value corresponds to two different y-values.

In conclusion, this table is not a function because no function can have the same x-values (3) for different y-values (5 and 6).

Two random numbers 180000000 and 0.00000534 can be written as 1.8 x 10⁸ and 5.34 x 10⁻⁶.

Numbers that are either too large or too little to be conveniently stated in decimal form can be expressed using scientific notation. It may be called scientific form.

When a number is written using only the digits of the number, that is considered standard notation. Since words are not used in conventional number notation, this is the way that numbers are typically written.

Let the bigger number by 180000000  and the smaller number be 0.00000534. The two numbers in scientific notations can be written as below:-

180000000   = 1.8 x 10⁸

0.00000534 = 5.34 x 10⁻⁶.

Therefore, two random numbers 180000000 and 0.00000534 can be written as 1.8 x 10⁸ and 5.34 x 10⁻⁶.

Answer  96

Hence 96%

So, 24/25

as a percentage is 96%

All done!

Answer:

96%

Step-by-step explanation:

First, divide 100 but 25 (the denominator) and you get 4. This means that to get a number over 100, which is a percentage you need to multiply the initial fraction by 4. You get 96/100, and you can remove the 100 to get 96%

The slope of the line that passes through the coordinates is -6/5.

The slope of the line is given by;

m = (y₂ - y₁)/(x₂ - x₁)

Where, the coordinates are given.

(x₁ ,y₁) = (2, 8)

(x₂, y₂) = (-3, 14)

Put the value in the slope;

m = (14 - 8)/(-3 - 2)

m = 6/-5

m = -6/5

[tex]3\sqrt{21}[/tex]

Step-by-step explanation:

By the Pythagorean theorem,

[tex]\sqrt{17^2-10^2}=\sqrt{189}=3\sqrt{21}[/tex]

The exponential model for the given data set is [tex]y(x) = 70 + (110)e^{-0.135x}[/tex].

Given that cake recipe says to bake the cake until the center is 180⁰F , then let the cake cool to 120⁰F and the table shows temperature readings for the cake and the room temperature is 70°F.

Temperature at time = 0 min, y₀= 180° F

Ambient (room) tempertaure = y₁ = 70° F

Using Newton's cooling method,

y(x) = y₁ + (y₀ - y₁)e⁻ⁿˣ

y(x) = 70 + (180-70)e⁻ⁿˣ

y(x) = 70 + (110)e⁻ⁿˣ

Given, at x=5 min, y(5) = 126,

y(5) = 70 + (110)e⁻⁵ⁿ  = 126

Solving,  e⁻⁵ⁿ  = (126-70)/110 = 0.5091

Taking and log and solving for n,

- 5n = log(0.5091)

-5n= -0.67511

n = 0.135

Thus, the exponential model is [tex]y(x)=70+(110)e^{-0.135x}[/tex]

Hence, an exponential model for given data set when a room temperature  of 70°F is [tex]y(x)=70+(110)^{-0.135x}[/tex].

We have expression ln a-2 ln b+1/3 ln c as a single natural logarithm

㏑ [tex](\frac{ac^{\frac{1}{3} }}{b^2} )[/tex]

A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.

Typically, the natural logarithm of x is denoted by the symbols ln x, loge x, or, if the base e is implicit, just log x. When adding parentheses for clarity, the values ln(x), loge(x), or log (x). In order to avoid ambiguity, this is notably done when the argument to the logarithm is not a single symbol.

The power to which e would need to be raised in order to equal x is the natural logarithm of x.

For instance, e2.0149... = 7.5, thus ln 7.5 equals 2.0149.

Since e1 = e, the natural logarithm of e itself, or ln e, is equal to 1, while the natural logarithm of 1 is 0, since e0 = 1.

We have been asked to express ln a-2 ln b+1/3 ln c as a single natural logarithm.

⇒ ln a-2 ln b+1/3

⇒ ㏑ (a) - ㏑ (b²) + ㏑ [tex]c^{\frac{1}{3} }[/tex]

Use the quotient property of logarithms for ln a-2 ln b

⇒ ㏑ [tex](\frac{a}{b^2} )[/tex] + ㏑ [tex]c^{\frac{1}{3} }[/tex]

Use the quotient property of logarithms for ㏑ [tex](\frac{a}{b^2} )[/tex] + ㏑ [tex]c^{\frac{1}{3} }[/tex]

⇒ ㏑ [tex](\frac{ac^{\frac{1}{3} }}{b^2} )[/tex]

The expression that is equivalent to (2x + 3)/4 is: A. x/2 + 3/4.

Express the given expressions in their simplest form to determine the expression that is equivalent to (2x + 3)/4.

A. x/2 + 3/4

Find the common denominator. The common denominator is 4. Therefore:

=  2(x) + 1(3)/4

= (2x + 3)/4

x/2 + 3/4 ≠ (2x + 3)/4

Thus, the expression, x/2 + 3/4 is equivalent to (2x + 3)/4.

B. x/2 - 3/4 = (2x - 3)/4

Therefore, x/2 - 3/4 ≠ (2x + 3)/4

C. 3x/4 + 3/4 = (3x + 3)/4

Therefore, 3x/4 + 3/4 ≠ (2x + 3)/4

D. 8x + 24 ≠ (2x + 3)/4

Therefore, 8x + 24 ≠ (2x + 3)/4

In summary, we can conclude that, the expressions, x/2 - 3/4, 3x/4 + 3/4, and 8x +24x/2 + 3/4 is not equivalent to (2x + 3)/4. Thus, the expression that is equivalent to (2x + 3)/4 is: A. x/2 + 3/4.

The actual area of the care park in hectares is 18.75

As per the known fact, ratio of measurement on scale is equal to the ratio of measurement in real. So, writing the equation first -

Area of car park = 3 cm²

Keep the value of 1 cm in the above mentioned equation.

Area of car park = 3 × (250)²

Taking square

Area of car park = 3 × 62,500

Performing multiplication

Area of car park = 1,87,500 m²

Converting the area in hectares

10,000 m² = 1 hectare

1,87,500 m² = (1 ÷ 10,000) × 1,87,500

1,87,500 m² = 18.75 hectares.

Therefore, the actual area of the care park is 18.75 hectares.
