To change a fraction into a decimal,  divide the numerator by denominator.  This gets you a decimal.  Example.
4/25 Oh OK!  4 divided by 25 equals.... 0.16!  GG

<span>To convert a Fraction to a Decimal manually,
follow these steps:</span><span><span>Step 1: Find a number you can multiply by the bottom of the fraction to make it 10, or 100, or 1000, or any 1 followed by 0s.</span><span>Step 2: Multiply both top and bottom by that number.</span><span>Step 3. Then write down just the top number, putting the decimal point in the correct spot (one space from the right hand side for every zero in the bottom number)</span></span>

Which of the following is the missing reason? Statements Reasons two thirds times x plus 7 equals negative 5 Given 2x 21 = â’15
pentagon [3]

The correct option is B. Distributive property

Given,

\frac{2}{3} x+7=-5\\

On solving the above equation,

multiplying both sides by 3 we, get

2x+21=-15

now subtracting 21 from both the sides,

2x=-36\\

dividing both the sides by 2 we get,

x=-18

Since in the above steps we follow all the giving property except the distributive property.

Hence the correct option is B. Distributive property.

Explain the special pattern for sketching a parabola
Lady bird [3.3K]

Answer:

the parabola can be written as:

f(x) = y = a*x^2 + b*x + c

first step.

find the vertex at:

x  = -b/2a

the vertex will be the point (-b/2a, f(-b/2a))

now, if a is positive, then the arms of the parabola go up, if a is negative, the arms of the parabola go down.

The next step is to see if we have real roots by using the Bhaskara's equation:

x =  \frac{-b +-\sqrt{b^2 -4ac} }{2a}

Now, draw the vertex, after that draw the values of the roots in the x-axis, and now conect the points with the general draw of the parabola.

If you do not have any real roots, you can feed into the parabola some different values of x around the vertex

for example at:

x =  (-b/2a) + 1 and x =  (-b/2a) - 1

those two values should give the same value of y, and now you can connect the vertex with those two points.

If you want a more exact drawing, you can add more points (like x =  (-b/2a) + 3 and x =  (-b/2a) - 3) and connect them, as more points you add, the best sketch you will have.

What is the volume of the following triangular prism?<br> 60 cm3<br> 12 cm3<br> 3.75 cm3<br> 6 cm3
DochEvi [55]
By definition, the prism volume is given by:
 V = Ab * L&#10; Where,
 Ab: base area
 L: long
 Substituting values we have:
V = ((1/2) * (12) * (2.5)) * (4)&#10; &#10;  V = 60 cm ^ 3
 Answer:
 The volume of the triangular prism is:
V = 60 cm ^ 3

Is 24 ft greater than 324 inches
Margaret [11]
First lets convert 24 ft into inches. Each foot has 12 inches so 24*12 equals 288. Now we have to see which one is greater 288 inches or 324 inches. 324 inches is greater so therefore 324 inches is greater than 24 ft
