To find the answer to that, you have to see how many numbers are between 13 and 31. There are 18 numbers between 13 and 31. Divide 18 by 2 and you will get the number halfway. 9 is halfway between 13 and 31. So, add 9 to 13 and you get 22.

The answer is 22.

12^2 + 6^2 = x^2
144 + 36 = x^2
180 = x^2
13.416407865 = x

rounded

x = 13.4

I dont know to put for the boxes. When I work the math out I get 5.4 more gallons but I'm confused on what to put for the other

aniked [119]

Step-by-step explanation:

One possible solution would be p being the total gallons of paint needed to buy, 250 in the first box (because 250 square feet per gallon), 250 in the second box (because you have 1 gallon = 250 sq. feet leftover) = 1600 (total)

A bird of species? A, when? diving, can travel six times as fast as a bird of species B top speed. If the total speeds for these

Inessa05 [86]

Answer:

Maximum speed of bird A is $192\,\,\frac{mi}{h}$

Maximum speed of bird B is $32\,\,\frac{mi}{h}$

Step-by-step explanation:

This is a problem with two unknowns: Max speed of bird A (we name that "A"), and max speed of bird B (we call that "B"). Now we can create two equations with these two unknowns, based on the info provided:

Equation 1): based on the phrase "bird A can travel six times as fast as bird B" we write:

$A=6\,*\, B\\A=6B$

Equation 2): based on the phrase; "the total speeds for these two birds is 224 miles per hour", we write:

$A+B=224\,\,\frac{mi}{h}$

Now, we use the first equation to substitute A in the second equation, ad then solve for the unknown B:

$A+B=224\,\,\frac{mi}{h}\\(6B)+B=224\,\,\frac{mi}{h}\\7B=224\,\,\frac{mi}{h}\\B=\frac{224}{7} \,\,\frac{mi}{h}\\B=32\,\,\frac{mi}{h}$

Now we can solve for the other unknown "A" using the substitution equation and the value of B we just found:

$A=6B\\A=6\,(32\,\,\frac{mi}{h})\\A=192\,\,\frac{mi}{h}$
