How do you make this into a equivalent to 5/12 please help me ASAP

antoniya [11.8K]

Hey there! :)

To find equivalent fractions, divide or multiply the numerator AND denominator by the same number.

Example: Multiply by 2

5 × 2 = 10
12 × 2 = 24

10/24

Example: Multiply by 3

5 × 3 = 15
12 × 3 = 36

15/36

Two fractions equivalent to 5/12 are:

- 10/24
- 15/36

Hope this helps :)

The base diameter and the height of a cone are both equal to x units.

HACTEHA [7]

By definition, the volume of a cone is given by:

$V = (\frac{1}{3}) * (\pi) * (r ^ 2) * (h)$

Where,

r: cone circular base radius

h: height of the cone

Substituting values we have:

$V = (\frac{1}{3}) * (\pi) * ((\frac{x}{2}) ^ 2) * (x)$

Rewriting the equation we have:

$V = (\frac{1}{3}) * (\pi) * (\frac{x^2}{4}) * (x)$

$V = (\frac{1}{12}) * (\pi) * (x ^ 3)$

Answer:

An expression that represents the volume of the cone, in cubic units is:

$V = (\frac{1}{12}) * (\pi) * (x ^ 3)$

Note: rewrite the options again.

Let f(x)= 8x³ + 16x² -15 and g(x) = 2x+1. f(x)/g(x).

N76 [4]

Answer:

f(x)/g(x) = 4x^2+6x-3 remainder -12

or

f(x)/g(x) = (4x^2+6x-3)/(2x+1) + (-12)/(2x+1)

or

((4x²+6x-3)-12)/(2x+1)

Step-by-step explanation:

f(x)= 8x³ + 16x² -15

g(x) = 2x+1.

Using long division,

f(x)/g(x) = 4x^2+6x-3 remainder -12

A point H is 20m away from the foot of a tower on the same horizontal ground. From the point H, the angle of elevation of the po

astra-53 [7]

Answer:

a. See Attachment 1

b. $PT = 12.3\ m$

c. $HT = 31.1\ m$

d. $OH = 28.4\ m$

Step-by-step explanation:

Calculating PT

To calculate PT, we need to get distance OT and OP

Calculating OT;

We have to consider angle 50, distance OH and distance OT

The relationship between these parameters is;

$tan50 = \frac{OT}{20}$

Multiply both sides by 20

$20 * tan50 = \frac{OT}{20} * 20$

$20 * tan50 = OT$

$20 * 1.1918 = OT$

$23.836 = OT$

$OT = 23.836$

Calculating OP;

We have to consider angle 30, distance OH and distance OP

The relationship between these parameters is;

$tan30 = \frac{OP}{20}$

Multiply both sides by 20

$20 * tan30 = \frac{OP}{20} * 20$

$20 * tan30 = OP$

$20 * 0.5774= OP$

$11.548 = OP$

$OP = 11.548$

$PT = OT - OP$

$PT = 23.836 - 11.548$

$PT = 12.288$

$PT = 12.3\ m$ (Approximated)

--------------------------------------------------------

Calculating the distance between H and the top of the tower

This is represented by HT

HT can be calculated using Pythagoras theorem

$HT^2 = OT^2 + OH^2$

Substitute 20 for OH and $OT = 23.836$

$HT^2 = 20^2 + 23.836^2$

$HT^2 = 400 + 568.154896$

$HT^2 = 968.154896$

Take Square Root of both sides

$HT = \sqrt{968.154896}$

$HT = 31.1\ m$ <em>(Approximated)</em>

--------------------------------------------------------

Calculating the position of H

This is represented by OH

See Attachment 2

We have to consider angle 50, distance OH and distance OT

The relationship between these parameters is;

$tan50 = \frac{OH}{OT}$

Multiply both sides by OT

$OT * tan50 = \frac{OH}{OT} * OT$

$OT * tan50 = {OH$

$OT * 1.1918 = OH$

Substitute $OT = 23.836$

$23.836 * 1.1918 = OH$

$28.4= OH$

$OH = 28.4\ m$ <em> (Approximated)</em>
