Answer:

For the top equation, x = 27 (I think you meant to put x - 27 = 0. If not, I can always edit my answer for you)

For the bottom, x = 3

Hope this helps! Have a grrrreat day lol

The gear ratio of two gears is the ratio of the number of teeth of the larger gear to the number of teeth of the smaller gear. I

VLD [36.1K]

Answer:

24 gear.

Step-by-step explanation:

It is given that $Gear A:Gear B=Gear B:Gear C$ .

$\dfrac{Gear A}{Gear B}=\dfrac{Gear B}{Gear C}$

Gear A = 36 teeth

Gear C = 16 teeth

Let gear B have x teeth.

$\dfrac{36}{x}=\dfrac{x}{16}$

On cross multiplication we get

$36\times 16=x\times x$

$576=x^2$

Taking square root on both sides.

$24=x$

Therefore, gear B have 24 teeth.

STALIN [3.7K]

Answer:

Use the slope formula.

Step-by-step explanation:

1. The slope formula is in the form of y2-y1/x2-x1.

2. Use one set of points as (x1, y1), and the other as (x2, y2).

3. Plug the points into the corresponding values of the slope formula.

4. Solve.

5. Your answer is -2/11.

Well if the perimeter is 36in, then divide by 6 sides (the prefix hex- means six) to get 6. Don't forget your unit of measurement to be 6in of each side. It would be nice to have the picture though so if you could suply me with that it would help out.

A spherical balloon is being deflated at a rate of 5 cubic centimeters per second. At what rate is the radius of the balloon cha

Dvinal [7]

Answer:

0.0048cm/s

Step-by-step explanation:

Volume of the spherical balloon is expressed as;

$V = 4/3 \pi r^3\\$

dV/dt = dV/dr * dr/dt

Given

dV/dt = 5cm³/s

dV/dr = 4πr²

Since V = 972picm³

972π = 4/3πr³

972 = 4/3r³

4r³ = 972 * 3

r³ = (972 *3)/4

r³ = 729

r = ∛729

r = 9cm

dV/dr = 4π(9)²

dV/dr = 324π

dV/dt = dV/dr * dr/dt

5 = 324πdr/dt

dr/dt = 5/324π

dr/dt = 5/324(3.14)

dr/dt = 5/1017.36

dr/dt = 0.0048cm/s

Help with this one please.

OverLord2011 [107]

The triangles formed by cutting the rectangle in half are congruent. If you calculate the area of the entire rectangle and then divide it by two, you will have the area of both those congruent triangles.

Answer:
$Area= \frac{base*height}{2}$

This is the formula for finding the area of any triangle given its base and its height.
