Answer:

A. AC=DE

Step-by-step explanation:

In the diagram it already shows that angle F and B are congruent. This means we just need to confirm the side. Choice C is not the answer because the points do not correspond to each other.

Which is the simplified form of the expression ((p squared) (q Superscript 5 Baseline)) Superscript negative 4 Baseline times ((

Alexus [3.1K]

Answer:

$q^{-30}$

Step-by-step explanation:

Given the expression:

$((p^2) (q ^5)) ^{-4} X ((p ^{-4}) (q^5)) ^{-2}$

First, we open the outer brackets

$=(p^{2X-4}) (q ^{5X-4})X (p ^{-4X-2}) (q^{5X-2})\\\\=(p^{-8}) (q ^{-20})X (p ^{8}) (q^{-10})\\\\$Next, we can collect like terms\\\\=p^{-8}Xp ^{8}Xq ^{-20}Xq ^{-10}\\\\$Applying addition law of indices\\\\=p^{-8+8}Xq^{-20+(-10)}\\\\=p^0 X q^{-30}\\\\=1 X q^{-30}\\\\=q^{-30}$

Therefore:

$((p^2) (q ^5)) ^{-4} X ((p ^{-4}) (q^5)) ^{-2}=q^{-30$

An electrician needs 14/3 rolls of electrical wire to wire each room in a house. How many rooms can he wire if he has 28/3 rolls

miv72 [106K]

Answer:

2 rooms

Step-by-step explanation:

To solve this, we need to figure out how many 14/3s go into 28/3. We know this because each room needs 14/3 rolls of wire, and we need to figure out how many rooms the electrician needs to wire with 28/3 rolls.

To find how many 14/3s go into 28/3, we can divide 28/3 by 14/3 to get

(28/3) / (14/3)

= (28/3) * (3/14)

= (28/14)

= 2

2 rooms is our answer
