Answer:

Largest number ins scientific notation: 1.4 x 10⁹ (Diameter of sun)

Step-by-step explanation:

We need to find the largest number ins scientific notation.

The number which has highest degree would be the largest.

In the given options, Diameter of Sun has highest power i.e 10⁹

All other options have lower degrees.

So, largest number ins scientific notation: 1.4 x 10⁹ (Diameter of sun)

Marat540 [252]

Answer:

7/30 of her music library

Step-by-step explanation:

We are looking for 7/10 of 1/3. In this case this "of" means we will multiply the two fractions. To multiply fractions, we multiply

top × top

and

bottom × bottom

1/3 × 7/10

is 1×7 on top, and

3×10 on the bottom.

= (1×7)/(3×10)

= 7/30

7/30 cannot be simplified, so that is the answer.

Answer:

Step-by-step explanation:

In order to eliminate, the numbers must eliminate. If the second equation is multiplied by 3, then the 3 and the -3 can be eliminated. Since it is multiple choice, we can plug in x = 12 and y = 10 to see if they are correct. 12 + 30 = 42 and 24 - 10 = 14, so D is correct.

Identify the property that justifies the following statement:<br> If <1≈ <2, then <2≈<1.

Colt1911 [192]

Symmetric property of congruence.

Solution:

Given statement:

If ∠1 ≅ ∠2, then ∠2 ≅ ∠1.

<em>To identify the property used in the above statement:</em>

Let us first know some property of congruence:

Reflexive property:

The geometric figure is congruent to itself.

That is $\overline{A B} \cong \overline{A B} \text { or } \angle B \cong \angle B$ .

Symmetric property of congruence:

If the geometric figure A is congruent to figure B, then figure B is also congruent to figure A.

That is $\overline{A B} \cong \overline{C D}, \text { then } \overline{C D} \cong \overline{A B}$ .

Transitive property of congruence:

If figure A is congruent to figure B and figure B is congruent to figure C, then figure A is congruent to figure C.

That is $\angle A\cong \angle B, \ \angle B\cong \angle C \ \text{then} \ \angle A\cong \angle C$

From the above properties, it is clear that,

If ∠1 ≅ ∠2 then ∠2 ≅ ∠1 is symmetric property of congruence.
