A formula is expressed as D= a(2+kt). Express k in terms of D,a, and t.

1 answer:

5 0

This is just rearranging terms, it gets kind of ugly though. Start by dividing both sides by a to get D/a=2+kt, next move the 2 over to the left to get (D/a)-2=kt, finally divide the whole expression by t to get ((D/a)-2)/t=k

ASAP ILL GIVE BRAINLIEST IF UR RIGHT!!! The radius of the cone is 5 in and y = 13 in. What is the volume of the cone in terms of

Blababa [14]

Answer: V = $100\pi$ $in^{3}$ (third option)

Given Information:

V = $\frac{1}{3}\pi r^{2} h$ <-- volume formula.
r = 5
y = 13
<em>h = ?</em>

To find h...

h, r, and y make a right triangle.
h and r are the two legs, y is the hyptenuse.
$h^{2} + r^{2} = y^{2}$
$h^{2} + 5^{2} = 13^{2}$
$h^{2} + 25 = 169$
$h^{2} = 144$
h = 12

Use formula:

V = $\frac{1}{3}\pi r^{2} h$
V = $\frac{1}{3} \pi (5)^{2} (12)$
V = $\frac{1}{3} \pi (25)(12)$
V = $\frac{1}{3} \pi (300)$
V = $100\pi$

Step-by-step explanation:

$\mathrm{Supplementary\:angles\:add\:up\:to}\:180^{\circ }$

$\angle \:GKO \mathrm{\:is\:supplementary\:angle\:of\:} \angle \:KNL$

$\mathrm{So\:}\angle \:GKO+\angle \:KNL=180$

$\angle \:GKO+61=180$

$\angle \:GKO=119$

Three consecutive even integers have a sum of -126. What is the smallest integer ?

SSSSS [86.1K]

Answer:

-40, - 42 and -44

Step-by-step explanation:

The fastes way here is trying. Lets pick a number, intelligently, and then work on it.

We need three even integers that sum -126. These will be all negative numbers and as they are consecutive they will be very similar (for example, -33 and -35 and -37). Thus, lets start by 1/3 of -126, which is -42:

(-42)+ (-44) + (-46) = - 132, so -42 no.

Lets go a step back: -40

(-40) + (-42) + (-44) = -126

So, the integers are -40, -42 and -44
