Answer:

x = 12

The measure of Angel A and Angle B = 144°

Step-by-step explanation:

Angle ∠ A= 10x+24∘

Angle ∠B=6x+72 ∘

Angle A and Angle B are Alternate interior angles hence, they are equal to each other.

Hence:

10x + 24 = 6x + 72

Collect like terms

10x - 6x = 72 - 24

4x = 48

x = 48/4

x = 12

The measure of ∠ A= 10x+24∘

=( 10(12) + 24)°

=( 120 + 24)°

= 144°

The Measure of Angle ∠B=6x+72 ∘

=( 6(12) + 72)°

= (72 + 72)°

= 144°

Answer:

∠A = 144 degrees

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The video game cost after six years is $16.

What is multiplication?

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

A video game costs $54 dollars after it is released. Every two years, retailers lower the price by multiplying it by 2/3.

Therefore, the cost of the video game after 6 years is,

Cost of video game after 6 years = $54 × (2/3)³ = $16

Hence, the video game cost after six years is $16.

Mr. Green’s hobby was restoring old houses. He recently purchased an old rundown house that needed a lot of repair, especially with the plumbing. The kitchen faucet dripped all day and night. It intrigued Mr. Green how much water dripped from this faucet in one day,but he surely didn’t want to sit and watch the faucet drip all day. So he figured that if he could discover how much water dripped within a certain time span, he could calculate the dripping rate for any time span. In his first observation he noted that 6 ounces of water dripped in 10 minutes.


A) Using Mr. Green's observation can you help him figure out how much water would have dripped in only 5 minutes? Show your work or explain your answer

Answers

Answer:

if you divide the rate like this 6oz/10min by two you get 3oz/5min. this

The land occupied today by Mexico was once home to a number of great civilizations. These ancient peoples made important contributions to such fields as city planning, architecture, science, mathematics and art. The Zapotec civilizations flourished between the first and sixth centuries. Within the lasting legacy of this people are numerous artifacts typifying pre-Columbian art-- -art dating to the times before the arrival of Columbus in 1492. The capital city of the Zapotec empire was Monte Alban, located in the highlands of Mexico. The Zapotec probably did not live within the city itself, which is thought rather to have served purely as a religious and ceremonial center. Evidence to support this assumption is the lack of a nearby water source. Within the city, Zapotec architects erected massive temples. One of these, which has survived, is known today simply as "Temple J." This structure dates to around 200 BC. Believed to have been an observatory, Temple J is shaped oddly, like an arrow. On its face are forty stones with carvings of places thought to have been conquered by the Zapotec.Another surviving artifact is the Figural Urn shown. The object, which was discovered in a tomb, likely contained the ashes of the deceased. Notice the abundance of geometric shapes and forms throughout the work. These are typical of Zapotec and other pre-Columbian cultures. How do i start a war on the Internet If 10^2=100,10^3=100010^4=10000,what is 1000^2/3 How does the Endocrine system work?
