On the 3.3-meter-long wall, hang five paintings with a side length of 0.48 square. For each two paintings, there is an equal interval between the painting and the wall. How many meters is the interval On the 3.3-meter-long wall, hang five paintings with a side length of 0.48 square. It is required that there is an equal interval between each two paintings and between the painting and the wall. How many meters is the length of each interval?

On the 3.3-meter-long wall, hang five paintings with a side length of 0.48 square. For each two paintings, there is an equal interval between the painting and the wall. How many meters is the interval On the 3.3-meter-long wall, hang five paintings with a side length of 0.48 square. It is required that there is an equal interval between each two paintings and between the painting and the wall. How many meters is the length of each interval?

5 pieces of square with side length of 0.48, length sum = 5 × 0.48 = 2.4 (m), remainder = 3.3-2.4 = 0.9 (m);
There are six equal intervals between the two paintings and between the painting and the wall
=0.9 △ 6 = 0.15 (m)

As shown in the figure below, on the 3.3-meter-wide wall, hang five paintings with a side length of 0.18 meters. It is required that there should be equal spacing between each two paintings and between the painting and the wall
How many meters is the length of each interval

Although I don't fully understand what you mean, I assume as follows
Question: if each painting is required to be hung at an equal distance, what is the distance between each painting, or what is the distance between the two sides of the wall?
Answer: if 5 paintings are square, the total length of no painting is 2.4m; if each painting is hung at an equal distance in the middle, the distance is 0.2m, and the distance from the walls on both sides is 5cm

The ladder AB = 2.5m, the top a is against the wall AC, the distance between the bottom B of the ladder and the corner C is 1.5m: the ladder stops at the de position after sliding, and the measured BD = 0.5m
How many meters did a slide at the top of the ladder? Is AE = BD?
Can AE be equal to BD when ladder top a continues to slide?

5, AE = BD. if you continue to slide, you can't

The ladder AB = 2.5m, the top a is against the wall AC, the distance between the bottom B of the ladder and the corner C is 1.5m: the ladder stops at the de position after sliding, and the measured BD = 0.5m
How many meters did a slide at the top of the ladder?

Pythagorean theorem AC = 2m
DC=2m
Pythagorean theorem CE = 1.5m
AC-CE=0.5m
That's 0.5m

The ladder is 25 meters long and leans against the wall. The top of the ladder is 7 meters away from the bottom of the wall. If it falls 4 meters, how many meters does the bottom of the ladder slide horizontally?
Add the calculation process!

Start:
The length of the bottom of the ladder is root (25 * 25-7 * 7) = 24
End situation:
The length of the bottom of the ladder is root (25 * 25-3 * 3) = 24.82
So it slid 0.82 meters horizontally

A ladder is 25 meters long, and one end of the ladder is 7 meters away from the wall. If the top of the ladder falls 4 meters, how many meters does the bottom of the ladder slide horizontally?

√25²-7²＝√625-49＝√576＝24
√ 25 & # 178; - (24-4) &# 178; = √ 625-400 = √ 225 = 15m
15-7 = 8 meters

A ladder is 2.5 meters long, leaning against the vertical wall. The root of the ladder is 0.7 meters away from the bottom of the wall. If the top of the ladder slides 0.4 meters, how many meters is the root of the ladder away from the bottom of the wall

x²＋0.7²＝2.5²,
x＝2.4m,
After sliding, the ladder heel is set to be y m away from the wall,
（2.4－0.4）²＋y²＝2.5²,
y＝1.5m
So it's 1.5 meters from the heel of the ladder to the bottom of the wall

As shown in the picture, a ladder is 5 meters long and leaning against a wall. The lower end B of the ladder is 1.4 meters away from the wall (1). How high is the top of the ladder from the ground?
As shown in the picture, a ladder is 5 meters long, leaning against a wall, and the low end B of the ladder is 1.4 meters away from the wall
(1) How high is the top of this ladder from the ground?
(2) If the top of the ladder falls 0.8 meters, how many meters does the low end of the ladder move horizontally?

1, Pythagorean theorem 4.8m
2, or Pythagorean theorem, the horizontal direction becomes 3 meters, so moving 3-1.4 = 1.6 meters

As shown in the figure, a ladder AB is 2.5 meters long, and the top a is against the wall AC. at this time, the distance between the bottom B of the ladder and the corner C is 1.5 meters. After sliding, the ladder stops at the position of De, and the measured BD length is 0.9 meters, then the top a of the ladder falls ()
A. 0.9m B. 1.3m C. 1.5m D. 2m

In RT △ ACB, ac2 = ab2-bc2 = 2.52-1.52 = 4, ∵ AC = 2, ∵ BD = 0.9, ∵ CD = 2.4. In RT △ ECD, EC2 = ed2-cd2 = 2.52-2.42 = 0.49, ∵ EC = 0.7, ∵ AE = ac-ec = 2-0.7 = 1.3

A ladder AB is 2.5 meters long, and the top a is against the wall AC. at this time, the distance between the bottom B of the ladder and the corner C is 1.5 meters. After the ladder slides, it stops at the de position, and the BD length is 0.5 meters. How many meters does the top a of the ladder slide?
