Given, ABC is a triangle, right-angled at C as shown below.
ABC is a triangle, right-angled at C. If AB = 25 cm and AC = 7 cm, find BC
So, we can apply the Pythagoras theorem here, if it is right-angled at C then the side opposite to C will be the hypotenuse of the triangle that is AB = 25 cm, and the other two sides are AC = 7 cm and BC.
Now, by applying the Pythagoras theorem i.e. in a right-angled triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides, we can find BC.
AB = 25 cm, AC = 7 cm and BC =?
In triangle ACB, By Pythagoras theorem, (Hypotenuse)2 = (Perpendicular)2 + (Base)2
(AB)2 = (AC)2 + (BC)2
(25)2 = (7)2 + (BC)2
625 = 49 + (BC)2
(BC)2 = 625 – 49
(BC)2 = 576
BC = 24 cm
Thus, BC is equal to 24cm

(read the passage)THE FIRST FLAG: Betsy Ross made her living as a seamstress, and had many customers. She sewed many things, including clothes, blankets, and curtains. Each day, she would start with a pile of cloth and create things people paid her to make for them. Everyone knew she would do a wonderful job, so they came to her home and asked her to make many items for them. Business was so good, and as she began to get very busy, Betsy hired me to help. I am an experienced seamstress, so I can sew very well.
On my first day, three men came to her home and asked if she could make a flag. I listened to them talk with great interest. One of them was named George Washington.1 I had heard of him, and now here he was right in front of me. He came to the store in May. I remember it very well because it was my birthday that day. Washington was leading the army, but the army did not currently have a flag. The army was fighting for freedom,2 but at the time no one knew if we would win.
The men showed Betsy Ross a drawing of the flag of the new country. It had stars and stripes. I said, “Silver stars would be great.” Betsy said, “No, it will be too difficult to make those. The flag should be red, white, and blue.” So we set to work that day.
We worked on the flag for a solid month. It would be very big. In addition to sewing the flag, we had to do other work, too. Betsy said we had to make more clothes to get money. We were making the flag as a present, which meant we would not be paid for the flag.
Finally the flag was complete, so George Washington sent someone to come get it. He opened it up and said, “This is it. This is just what we need to inspire the army.” He did not show it to anyone yet, though. He kept it for a special day.
On July 4th, the army flew the new flag. That was the first Independence Day. On that day, the United States said it was a new country. It had a new flag. We were not there, but we heard about it later.
The army had to fight more battles. Just saying they were independent did not make it true. The war went on for 7 more years. We worried. We made more flags. In all those battles, soldiers saw that flag. Still, it was difficult to win.
When the war ended, the country started. I was proud when I saw the flag. I didn’t just make a flag. I was part of making the United States.

The main idea of this excerpt is that A. people have the right to break ties with a government and express their reasons for doing so.
The passage emphasizes the belief that when a situation arises where it becomes necessary for a group of people to separate from a governing authority, they have the right to assume an independent and equal status among the nations of the world. It asserts that this right is justified by the laws of nature and a higher power.
The excerpt highlights the importance of publicly declaring the causes that motivate such a separation, emphasizing that a respectful consideration for the opinions of others requires the expression of these reasons. The passage reflects the idea of self-determination and the belief that individuals have the right to establish their own political destiny and shape their governance based on their own values, interests, and principles.
In summary, the main idea of this excerpt is the affirmation of people's right to dissolve political bands, assert their independence, and provide a justifiable declaration of the reasons for their separation. Therefore, Option A is correct.

A seed is the developing portion of a new plant and as such is alive, but dormant, and needs to be buried in soil or another suitable material to begin the renewal process.
The seeds we utilize to grow food are at least living. If seeds are not adequately cared for, they can perish from extremes of heat, cold, or moisture. But given the correct circumstances, they just go into dormancy.

how did problems in the manufacturing industry contribute to growing weakness in the U.S. economy during the 1920s?
Answers
Problems in the manufacturing industry contribute to growing weakness due to excessive production and excess stock.
Problems in the manufacturing industry contributed significantly to the growing weakness in the U.S. economy during the 1920s. One major factor was overproduction, which occurred due to the development of new technologies and mass production techniques. This led to a surplus of goods and a decline in prices, reducing profits for manufacturers.
Additionally, there was a lack of consumer demand for these goods, as many people were already heavily in debt from buying on credit. This led to a slowdown in production, which in turn led to layoffs and reduced consumer spending, creating a vicious cycle that contributed to the onset of the Great Depression in 1929.

The Earth's surface (ocean and land) is finest when viewed from inland toward the land.
In the event of a land wind, will the ocean current flow toward or away from land?
When wind comes inland from the sea and toward land, it is referred to as a sea breeze. Due to the greater temperature differential between the water and the neighboring land in the spring and summer, this breeze is most frequent in the afternoon when the land is being heated by the sun to its highest level.Because of the disparity in temperatures between land and water, there are two types of breezes: land and sea. Coastal regions are where these are primarily seen. Sea breeze, as opposed to land breeze, is the movement of wind from the sea to the land.To learn more about Land breeze refer to:

Answers
CD is perpendicular to AB and passes through point C(5, 12). If the coordinates of A and B are (-10, -3) and (7, 14), respectively, the x-intercept of CD is Reset Next.
The point Submit Test Reader Tools lies on CD is (17, 0)
Point (-2, 19) lies on CD
Find slope of AB:
\(m = \frac{y2 - y1}{x2-x1}\)
x1, y1 = (-10, -3)x2, y2 = (7, 14)\(m = \frac{14 + 3}{7 +10}\)
m = 1
Therefore,
1 × slope of CD
slope of CD = -1
Substitute m = -1 and (x, y) = (5, 12) in eq. 1
12 = -1(5) + c
c = 12 + 5
c = 17
Substitute m = -1 and c = 17 in eq. 1
y = -x + 17 ------ eq. 2
The x-intercept is found by setting y equal to 0
0 = -x + 17
x = 17
Thus, x intercept of CD is (17, 0)
Substitute (x, y) = (-5, 24) in eq 2
(-5.24) 24-(-5)+17-245+1724 = 22
