What is an equivalent ratio to 7:5A 14:12B 21:10C 21:15PLZ help me

Look at all the options.

Let's look at the 5 in the ratio. A number of an answer choice has to be divisible by 5. We can already say A isn't the right answer, because we can't multiply 5 to 12.

All the 7 factors are equal to 21.

7*3= 21

So, shouldn't we multiply by 3 for the 5 as well?

3*5= 15

The correct answer is 21:15 or "C".

I hope this helps!

What is the value of h when the function is converted to vertex form?

elena-s [515]

Answer: h=7

Step-by-step explanation:

By definition the function in vertex form is:

$f(x)=a(x-h)^{2}+k$

Where (h,k) is the vertex of the parabola.

You must group the terms that contain the same variable in the function:

$f(x)=(x^{2}-14x)+29$

Complete the square as following:

$f(x)=(x^{2}-14x+49)+29-49$

Now you must rewrite it as following:

$f(x)=(x-7)^{2}-20$

Then:

h=7

What causes global convection current to form

hoa [83]

Answer:

Hope this helped :)

Step-by-step explanation:

Convection flows structure in light of the fact that a warmed liquid grows, getting less thick. The less-thick warmed liquid ascents from the warmth source. ... For example, a hot radiator warms the air promptly around it. The air ascends toward the roof, pulling cooler air down from the roof into the radiator to be warmed.
