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}

This graph shows a proportional relationship.
Nonamiya [84]
Not quite sure but:
2/3 = 3/4
divide all by 2/3 to get a 1 value so
1 = 0.8

Given the expression: 5x^10-80x^2 Part A: Rewrite the expression by factoring out the greatest common factor
Jlenok [28]

Answer:

A) 5x²(x^(8) - 16)

B) 5x²[(x⁴ + √16) • (x² + ∜16) • (x + (8√16) • (x - (8√16))]

Step-by-step explanation:

We are given the expression;

5x^(10) - 80x²

A) Since the expression is, 5x^(10) - 80x², the greatest common factor is 5x². So we will factorize that out.

So, we have;

5x²(x^(8) - 16)

B) The complete factorization of 5x²(x^(8) - 16) will be;

5x²[(x⁴ + √16) • (x⁴ - √16)]

Now, (x⁴ - √16)] can be broken than further into;

(x² + ∜16) • (x² - ∜16)

Also, (x² - ∜16) can be broken down into;

[(x + (8√16) • (x - (8√16))

So, our complete factorization gives us;

5x²[(x⁴ + √16) • (x² + ∜16) • (x + (8√16) • (x - (8√16))]

Whats the sum of fifty-two and twenty
Anastasy [175]
Well, sum means addition, so I'm gonna add together 52 and 20.

52
20 +
--------

I start at the ones, and see that 2 + 0 is 2, so drop a 2 below them

52
20 +
--------
2

now, look at the tens place. we add together what we see in the tens place and put it below. 5+2 is 7, so we put that under 5 and 2.

52
20 +
------
72 we see that our final answer is 72, so the sum of 52 and 20 is 72.
