What does equivalent fracations means?

Diano4ka-milaya [45]

Answer:

Equivalent fractions are fractions that have the same value or amount even if they seem different. They are a type of fraction that are equivalent in nature.

Step-by-step explanation:

Equivalent means being equal in value, function, amount or meaning. Even if they seem different they are the same in their own way (and I'm talking about fractions now)

The temperature in degrees Celsius can be determined using the expression 5 9 (F – 32) where F is the temperature in degrees Fah

Norma-Jean [14]

Answer:

The temperature on Celsius scale for 86 ºF is 30 ºC.

Step-by-step explanation:

Both degrees Celsius and Fahrenheit are relative scales of temperature. The relationship between degrees Fahrenheit and degrees Celsius is summarized by the equation below:

$T_{C} = \frac{5}{9}\cdot (T_{F}-32)$ (1)

Where:

$T_{F}$ - Temperature, measured in degrees Fahrenheit.

$T_{C}$ - Temperature, measured in degrees Celsius.

If we know that $T_{F} = 86\,^{\circ}F$ , then its equivalent temperature on Celsius scale is:

$T_{C} = \frac{5}{9}\cdot (86-32)$

$T_{C} = 30\,^{\circ}C$

The temperature on Celsius scale for 86 ºF is 30 ºC.

4. A store had 86 DVDs and 52 CDs. When the equal number of DVDs and CDs were sold,

11Alexandr11 [23.1K]

Answer:

51 DVDs

Step-by-step explanation:

Let the number of DVDs and CDs sold be x each.

<u>Initial</u>

Number of DVDs= 86

Number of CDs= 52

<u>After selling</u>

Number of DVDs= 86 -x

Number of CDs= 52 -x

Given that there are 3 times as many DVDs than CDs left,

86 -x= 3(52 -x)

<em>Expand:</em>

86 -x= 156 -3x

<em>Bring x terms to 1 side, constant to the other:</em>

3x -x= 156 -86

<em>Simplify:</em>

2x= 70

<em>Divide both sides by 2:</em>

x= 35

Amount of DVDs left

= 86 -x

= 86 -35

= 51

Let line $l_1$ be the graph of $5x + 8y = -9$. Line $l_2$ is perpendicular to line $l_1$ and passes through the point $(10,10)$.

SashulF [63]

Answer:

m + c = - 4.4

Step-by-step explanation:

Line 1 is given by the equation 5x + 8y = -9, ⇒ $y = - \frac{5}{8} x - \frac{9}{5}$ ........(1) {In slope-intercept form}

If line 2 is perpendicular to the line 1 then the equation of line 2 will be

$y = \frac{8}{5} x + c$ ........ (2), where c is a constant. {Since the product of the slopes of two perpendicular straight line is -1}

Now, the line 2 passes through the point (10,10).

So, from equation (2), we get,

$c = y - \frac{8}{5} x = 10- \frac{8 \times 10}{5} = - 6$

Therefore, the equation of line 2 will be $y = \frac{8}{5} x - 6$

This equation is in y = mx + c form where $m = \frac{8}{5} = 1.6$ and c = - 6

Hence, m + c = 1.6 - 6 = - 4.4 (Answer)
