Answer C is correct because 2×(4×305) is the same as (2×4)×305 and 2×4=8.

Hey! Can someone please help me with this question? Really appreciate it

Answer:

$d = 0.112* 10^3$

Step-by-step explanation:

Given

$h = 8.4 * 10^3$

$d = \sqrt{\frac{3h}{2}}$

Required

Find d

We have:

$d = \sqrt{\frac{3h}{2}}$

Substitute: $h = 8.4 * 10^3$

$d = \sqrt{\frac{3*8.4 * 10^3}{2}}$

$d = \sqrt{\frac{25.2 * 10^3}{2}}$

$d = \sqrt{12.6 * 10^3}$

Express as:

$d = \sqrt{1.26 *10* 10^3}$

$d = \sqrt{1.26 *10^4}$

Split

$d = \sqrt{1.26} *\sqrt{10^4}$

$d = 1.122* 10^2$

To write in form of: $a * 10^b$

The value of a must be: $0 \le a \le 1$

So, we have:

$d = 0.1122* 10 * 10^2$

$d = 0.1122* 10^3$

Approximate

$d = 0.112* 10^3$

Use the commutative property of multiplication to identify which expression is equivalent to 6(2)(x).

11Alexandr11 [23.1K]

The commutative property is when you change the order but not the answer. To better understand what they are asking you, let's let x=1- 6 * 2 * 1=12; Answer A wouldn't be right because there are no 6,2, or x's. Remember you just change the ORDER not the GROUPING so Answer B is wrong too. Now Answer C and Answer D are left. Now you just need to look at the signs. 6(2) just means 6 TIMES 2 so pick the option with multiplication. So your answer is C. Hope I helped!

In the figure shown, r || s. If the measure of ∠ 2 = 146°, what is the measure of ∠ 7

borishaifa [10]

Answer:

34°

Step-by-step explanation:

1. First, let's find the measure of ∠1 because since r || s, that means ∠1 = ∠7 because they're both alternate exterior angles. Alternate exterior angles are congruent.

2. (Solving for ∠1)

$146 + x = 180$
$146 + x - 146 = 180 - 146$
$x = 34$

3. Now, since we know ∠1 = ∠7, ∠7 = 34°.
