Answer:

If the signs of rational numbers are same, then the answer is positive.

If the signs of rational numbers are different, then the answer is negative.

Step-by-step explanation:

Consider the provided information.

A: When multiplying or dividing rational numbers, when will the answer be positive?

If we are multiplying or dividing rational numbers the answer will be positive if and only if both the rational numbers have same sign.

For example: Multiply 2 and 4.

2×4=8 (same sign)

Multiply -2 and -4.

-2×-4=8 (same sign)

8 is a positive rational number.

Now divided 2 and 4.

$\frac{2}{4} =\frac{1}{2}$

Divided -2 and -4.

$\frac{-2}{-4} =\frac{1}{2}$

1/2 is a positive rational number.

Hence, If the signs of rational numbers are same, then the answer is positive.

B: When multiplying or dividing rational numbers, when will the answer be negative?

If we are multiplying or dividing rational numbers the answer will be negative if and only if both the rational numbers have different sign.

For example: Multiply 2 and -4.

2×-4=-8 (different sign)

Multiply -2 and 4.

-2×4=-8 (different sign)

-8 is a negative rational number.

Now divided 2 and -4.

$\frac{2}{-4} =-\frac{1}{2}$

Divided -2 and 4.

$\frac{-2}{4} =-\frac{1}{2}$

-1/2 is a negative rational number

Hence, If the signs of rational numbers are different, then the answer is negative.

In ΔOPQ, the measure of ∠Q=90°, the measure of ∠O=26°, and QO = 4.9 feet. Find the length of PQ to the nearest tenth of a foot.

Step2247 [10]

Given:

In ΔOPQ, m∠Q=90°, m∠O=26°, and QO = 4.9 feet.

To find:

The measure of side PQ.

Solution:

In ΔOPQ,

$m\angle O+m\angle P+m\angle Q=180^\circ$ [Angle sum property]

$26^\circ+m\angle P+90^\circ=180^\circ$

$m\angle P+116^\circ=180^\circ$

$m\angle P=180^\circ -116^\circ$

$m\angle P=64^\circ$

According to Law of Sines, we get

$\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}$

Using the Law of Sines, we get

$\dfrac{p}{\sin P}=\dfrac{o}{\sin O}$

$\dfrac{QO}{\sin P}=\dfrac{PQ}{\sin O}$

Substituting the given values, we get

$\dfrac{4.9}{\sin (64^\circ)}=\dfrac{PQ}{\sin (26^\circ)}$

$\dfrac{4.9}{0.89879}=\dfrac{PQ}{0.43837}$

$\dfrac{4.9}{0.89879}\times 0.43837=PQ$

$2.38989=PQ$

Approximate the value to the nearest tenth of a foot.

$PQ\approx 2.4$

Therefore, the length of PQ is 2.4 ft.

Answer:

NO, YES, YES, NO

Step-by-step explanation:

Subsitute the number they give you and then solve. Finally, see if the equation is true.

13 - 7 = 20 This is equation is not true. (NO)

15 · 8 = 120 This equation is true. (YES)

24/12 = 2 This equation is true. (YES)

5 = 10 + 5 This equation is not true. (NO)
