Answer:

■ A random sample of dogs at different animal shelters in Abu Dhabi shows that 12 of the 60 dogs are puppies. Abu Dhabi's animal shelters collectively house 1,200 dogs each year. About how many dogs in all of the city’s animal shelters are puppies?

➢12/60 are puppies. 60 are the number of dogs, 12 is number of puppies.

If there are 1200 dogs, we focus on the 60. 1200/60= 20

Whatever we do to the denominator we do to the numerator, so since we can multiply 60 by 20 to get 1200; we need to multiply 12 by 20 to get the total number of dogs. Which is 240.

60/1200 = x/20 1200x /1200 =12/20 x =240

Answer:

240

Step-by-step explanation:

1) First you set up a proportion.

2) You do 12/60=x/1,200.

3) You cross multiply and do 12x1,200. Your answer is 14400.

4) Then you do 14400/60=240

An oil company fills 1 over 10 of a tank in 1 over 5 hour. At this rate, which expression can be used to determine how long it w
Paladinen [302]

If 1/10 of the tank is filled in 1/5 of an hour, then multiplying both of those by 5 you would get 5/10 of a tank being filled in a full hour, or answer choice A. Hope this helps! By the way, sorry for the incorrect answer a couple years ago :)

Two gears are connected and are rotating simultaneously. The smaller gear has a radius of 2 inches, and the larger gear has a ra
sleet_krkn [62]

Answer:

Let r represent the radius of the smaller circle and R the radius of the larger circle.

Apply ratios: the radius of smaller circle to radius of larger circle, i.e.

r: R = 3 : 7.

I complete rotation = 360 degrees.

Part 1:

For one complete rotation of the smaller circle, the larger circle is rotated through: (3/7)*(360) = 154.3 degrees

Part 2:

For one complete rotation of the larger circle, the larger circle is rotated through: (7/3)*(360) = 840.0 degrees

This is equivalent to (840/360) = 2.3 rotations

Alternatively, use the ratios:

The number of rotations = R/r = 7/3 = 2.3 rotations

CALCULUS EXPERT WANTED. Can someone solve this or at least try to explain to me the fundamental theorem of calculus (FTC).
Amanda [17]

a. By the FTC,

\displaystyle\frac{\mathrm d}{\mathrm dx}\int_1^{\cos x}(t+\sqrt t)\,\mathrm dt=(\cos x+\sqrt{\cos x})\dfrac{\mathrm d}{\mathrm dx}\cos x=-\sin x(\cos x+\sqrt{\cos x})

b. We can either evaluate the integral directly, or take the integral of the previous result. With the first method, we get

\displaystyle\int_1^{\cos x}(t+\sqrt t)\,\mathrm dt=\dfrac{t^2}2+\dfrac{2t^{3/2}}3\bigg|_{t=1}^{t=\cos x}=\left(\dfrac{\cos^2x}2+\dfrac{2(\cos x)^{3/2}}3\right)-\left(\dfrac12+\dfrac23\right)

=\dfrac{\cos^2x}2+\dfrac{2\sqrt{\cos^3x}}3-\dfrac76

c. The derivative of the previous result is

\dfrac{2\cos x(-\sin x)}2+\dfrac{2\cdot\frac32(\cos x)^{1/2}(-\sin x)}3=-\sin x\cos x-\sin x\sqrt{\cos x}

which is the same as the answer given in part (a), so ...

d. ... yes
