Roni wants to write an equation to represent a proportional relationship that has a constant of proportionality equal to Start Fraction 7 over 25 End Fraction. She writes the equation y = x + Start Fraction 7 over 25 End Fraction. What error is Roni making?

A. She should have written y = negative x + StartFraction 7 over 25 EndFraction so that x and y have a constant sum.

B. She should have written x y = StartFraction 7 over 25 EndFraction so that x and y have a constant product.

C. She should have written y = StartFraction 7 over 25 EndFraction x so that x and y have a constant quotient.

D. She should have written y = StartFraction 7 over 25 EndFraction so that y has a constant value.

Answer:

this is 8 raise to power 18

Answer:

8^18.

Step-by-step explanation:

The Law of exponents.

(x^a)^b) = x^(ab)

Why this happens?

(8^6)^3

Imagine you have 8^6.

8*8*8*8*8*8 to the power of three or ^3.

(8*8*8*8*8*8)^3.

8*8*8*8*8*8*8*8*8*8*8*8*8*8*8*8*8*8*8*8 which = 8^18.

This is why (8^6)^3=(8^(6*3) or 8^18.

Answer:

a¹⁸b²⁴c⁵⁴

Step-by-step explanation:

(aᵇ)ᶜ = aᵇᶜ = aᵇ×ᶜ

(-aⁿ)ᵒᵈᵈ = -aⁿ

(-aⁿ)ᵉᵛᵉⁿ = aⁿ

aⁿ × aⁿ = aⁿ⁺ⁿ

_________

In this situation, 6 is an even exponent which means that the negative coefficient of this 9th degree monomial will be positive. Now the only step is to multiply the exponents by the exponent outside of the perenthesis which is 6.

so (-a³b⁴c⁹)⁶ = ((-a³)⁶(b⁴)⁶(c⁹)⁶) = ((a³ˣ⁶)(b⁴ˣ⁶)(c⁹ˣ⁶)) = ((a¹⁸)(b²⁴)(c⁵⁴)) = a¹⁸b²⁴c⁵⁴

Answer:

28.

Step-by-step explanation:

28 is the correct answer using the mathematical format given by the percentage supplying us with the variable then by 50 the answer would be 28.

Answer:

a) 7.07

Step-by-step explanation:

5^2 + 5^2 = x^2

50 = x^2

x = 7.07

Given:

To find: The distance between the two points.

Answer:

Formula to find the distance:

[tex]\sf Distance\ =\ \sqrt{\Bigg(x_2\ -\ x_1\Bigg)^2\ +\ \Bigg(y_2\ -\ y_1\Bigg)^2}[/tex]

From the given data, we have:

Using them in the formula,

[tex]\sf Distance\ =\ \sqrt{\Bigg(-8\ -\ 2\Bigg)^2\ +\ \Bigg(-2\ -\ (-2)\Bigg)^2}\\\\\\\\Distance\ =\ \sqrt{\Bigg(-10\Bigg)^2\ +\ \Bigg(-2\ +\ 2\Bigg)^2}\\\\\\\\Distance\ =\ \sqrt{100}\ =\ \bf 10\ units.[/tex]

Therefore, the distance between (2, -2) and (-8, -2) is 10 units.

Hope it helps. :)

Answer: $84

Step-by-step explanation: If the phone costs 120 and it’s reduced by 30% all you have to do is 120 multiplied by 0.3 which equals 36. So you take the original price and subtract it by 36. your answer will be 84

Answer:

so if she hike 12 km every 4 hours, how many km could she hike in 6 hours.

first u have to find the equation. 12 km=4hours

? =6hours

and then you have to multiply 12 km by 6 hours and divide the results by 4 which is 12×6÷4. the final answer will be 18 kilometers.

Answer: The anwser is C

Step-by-step explanation:

It is asking for the total and the tax was 4% of it is not neede at all i did a question simalar to this so yeah.

Answer:

Use cross product to determine if the two ratios form a proportion. Here we can see that 2/16 and 5/40 are proportions since their cross products are equal. Percent means hundredths or per hundred and is written with the symbol, %. Percent is a ratio were we compare numbers to 100 which means that 1% is 1/100.

Step-by-step explanation:

Simple interest show proportional reasoning and relate to the percentage equation.

means,

[tex]\dfrac{\text{Parts}}{Whole}\times 100= \text{Percentage}[/tex]

Similarly,

when a percent gets multiplied by total it gives the number of parts taken means,

[tex]\text{Parts} = \text{percent} \times\text{whole}[/tex]

Here we can see that 3/15 and 6/44 are proportions, since their cross products are equal.

Percent means hundredths or per hundred and is written with the signal, %. Percent is a ratio where we compare numbers to 100 which means that 1% is 1/100.

Therefore, simple interest show proportional reasoning and relates to the percentage equation.
