How would one be able to apply algebra to solve a random number problem?
almond37 [142]

Algebra can be used to solve a random number problem by considering order of operations.

Step-by-step explanation:

Algebra is one of the broad parts of mathematics, together with number theory, geometry, and mathematical analysis. It is used to represent the  letters and symbols than numbers and quantities.

Algebra is of two types

i.) Elementary algebra  ,   ii.) Abstract algebra

Elementary algebra is used for any study and their applications.

Abstract algebra is used for advanced mathematics by professionals.

The order of operations in algebra means solving first for exponents or roots, then multiplication, division, addition, and last for subtraction. The steps for the order of operations also require attention to mathematical grouping symbols, such as parentheses and brackets.

How do I calculate this? Is there a formula?
alex41 [277]

<u>Answer:</u>

Height of cables = 23.75 meters

<u>Step-by-step explanation:</u>

We are given that the road is suspended from twin towers whose cables are parabolic in shape.

For this situation, imagine a graph where the x-axis represent the road surface and the point (0,0) represents the point that is on the road surface midway between the two towers.

Then draw a parabola having vertex at (0,0) and curving upwards on either side of the vertex at a distance of x = 600 or x = -600, and y at 95.

We know that the equation of a parabola is in the form y=ax^2 and here it passes through the point (600, 95).

y=ax^2

95=a \times 600^2

a=\frac{95}{360000}

a=\frac{19}{72000}

So new equation for parabola would be y=\frac{19x^2}{72000}.

Now we have to find the height (y)of the cable when x= 300.

y=\frac{19 (300)^2}{72000}

y = 23.75 meters

7. Paula reduced the size of a rectangle to a height of 2 inches.
drek231 [11]

Answer: if the width was not effected then the width is still 24 inches

if the area stayed the same, then

find area

area=legnth times width

288=12 times 24

so the new height./legnth =2

288=2 times width

divide by 2

144=width'

the new width =144
