An ostrich egg weighs 64 ounces is the weight of the ostrich egg greater than 5 pounds?
IgorLugansk [536]

Answer:

An ostrich egg is 4 pounds, therefore, an ostrich egg is not greater than 5 pounds.

Step-by-step explanation:

Convert the ounces to pound.

1 pound = 16 ounces

Next, divide.

64 ÷ 16 = 4.

4 < 5

So, an ostrich isn't greater than 5 pounds

Have a wonderful day!

What are the possible rational roots of the polynomial equation?<br><br> 0=2x7+3x5−9x2+6
RoseWind [281]

Answer: \pm\frac{1}{1}, \pm\frac{1}{2},\pm\frac{2}{1},\pm\frac{3}{1}, \pm\frac{3}{2}

Step-by-step explanation:

We can use the Rational Root Test.

Given a polynomial in the form:

a_nx^n +a_{n- 1}x^{n - 1} + … + a_1x^1 + a_0 = 0

Where:

- The coefficients are integers.

- a_n is the leading coeffcient (a_n\neq 0)

- a_0 is the constant term a_0\neq 0

Every rational root of the polynomial is in the form:

\frac{p}{q}=\frac{\pm(factors\ of\ a_0)}{\pm(factors\ of\ a_n)}

For the case of the given polynomial:

2x^7+3x^5-9x^2+6=0

We can observe that:

- Its constant term is 6, with factors 1, 2 and 3.

- Its leading coefficient is 2, with factors 1 and 2.

 Then, by Rational Roots Test we get the possible rational roots of this polynomial:

\frac{p}{q}=\frac{\pm(1,2,3,6)}{\pm(1,2)}=\pm\frac{1}{1}, \pm\frac{1}{2},\pm\frac{2}{1},\pm\frac{3}{1}, \pm\frac{3}{2}

vesna_86 [32]

Answer:

C.  

x + 0.05x = 3.15, which has one solution

Step-by-step explanation:

Let x = the price Joshua pays for the pack of pens

He add 5% (=.05 in decimal form)

That is x* .05

The new cost is 3.15

x+.05x = 3.15

This will have one solution
