The factors of 72 = 2, 2, 2, 3, 3,

So the highest facor they both share is 3

The GCF of 18 and 72 would be 3.

Since 3 is the highest number that goes into both 18 & 72.

Hope this helps,

Davinia.

6 dogs are black, 5 dogs are white, and the rest are blue. If there are 15 dogs in total, how many are blue?
Bezzdna [24]

Answer:

4 blue dogs

Step-by-step explanation:

Since there are 6 black dogs and 5 white dogs, there is 11 black and white dogs. There is 15 dogs in total, so you subtract 11 from 15, and that is 4. So, 4 dogs are blue.

Can someone help me please ???????
Inessa [10]

Answer:

d=1

Step-by-step explanation:

Factor d^2 - 2d - 8 into (d-4)(d+2)

Move -2/d+2 onto the other side, changing it into 2/d+2.

\frac{-3d}{(d-4)(d+2)} +\frac{3}{d-4}+\frac{2}{d+2} = 0

Let the empty side equal zero.

Add 3/d-4 and 2/d+2

\frac{5d-2}{(d+2)(d-4)}

Then add that to -3d.

\frac{2d-2}{(d+2)(d+4)}

Multiply 0 by d+2 and d-4 to get 2d-2 by itself.

2d=2

d=1

I can't edit the equation, but it's d-4 althroughout the question. Sorry for being so slow.

Just need to know the fraction
Reptile [31]
<h3>Answer:  1/2</h3>

The midsegment is always exactly half as long compared to the side it's parallel to.

Put another way, the longer side (4x+20) is twice long as the midsegment (3x).

one angle of a triangle is 2 / 3 of a right angle . the greater of the other to exceed the lesser by 20 degree. Find the angles
jarptica [38.1K]
2/3 of a right triangle is 60 degrees.  Then x + (x+20) + 60 = 180 total.

2x + 80 = 180, so 2x = 100 and x = 50.  The angles are 50, 70 and 60 (degrees)

Please show me how to solve the initial value problem <br> y'=tanx y(pi/4)=3
AlexFokin [52]
The ODE is separable, i.e. you can write

\dfrac{\mathrm dy}{\mathrm dx}=\tan x\iff\mathrm dy=\tan x\,\mathrm dx

Integrating both sides gives the general solution.

\displaystyle\int\mathrm dy=\int\tan x\,\mathrm dx
y=-\ln|\cos x|+C

Given that y\left(\dfrac\pi4\right)=3, we have

3=-\ln\left|\cos\dfrac\pi4\right|+C
3=-\ln\dfrac1{\sqrt2}+C
3-\ln\sqrt2=C


and so the particular solution to the IVP is

y=-\ln|\cos x|+3-\ln\sqrt2
y=3-\ln|\sqrt2\cos x|
