Answer:

**Answer:**

Isosceles

**Step-by-step explanation:**

If BD is an altitude, it splits triangle ABC into 2 triangles. It is also a median, so it splits the angle ABC into 2 congruent angles. Angle ABD and CBD are congruent. That means that angles A and C are congruent. This is true because the 2 angles at D are both right angles. Because of this, side AB and side CB are congruent. That means that this is an isosceles triangle.

**Answer:**

x=0

**Step-by-step explanation:**

9x-7=-7

Add 7 to each side

9x-7+7=-7+7

9x = 0

Divide each side by 9

9x/9 = 0/9

x = 0

9x - 7 = -7

(Add 7 to the other side)

9x = -7 + 7

9x = 0

=> x = 0

(You can substitute x back to check for the answer)

9(0) - 7 = -7

0 - 7 = -7

(Add 7 to the other side)

9x = -7 + 7

9x = 0

=> x = 0

(You can substitute x back to check for the answer)

9(0) - 7 = -7

0 - 7 = -7

The temperature was in the range of 10-13 on 7 of the days.

Give it the weight of the middle of the range = 11.5 for 7 times = 80.5

The temperature was in the range of 14-17 on 9 of the days.

Give it the weight of the middle of the range = 15.5 for 9 times = 139.5

The temperature was in the range of 18-21 on 16 of the days.

Give it the weight of the middle of the range = 19.5 for 16 times = 312

The temperature was in the range of 22-25 on 22 of the days.

Give it the weight of the middle of the range = 23.5 for 22 times = 517

The temperature was in the range of 26-29 on 6 of the days.

Give it the weight of the middle of the range = 27.5 for 6 times = 165

Total weight for all ranges = (80.5 + 139.5 + 312 + 517 + 165) = 1,214

Total number of days = 60

Estimated mean temperature = (1,214) / (60) =__20.23°C __

I really don't understand, can you show any more information?

**Answer:**

To find the number of D's in the school, we can use the given ratio of D's to A's and the number of A's provided.

The ratio of D's to A's is given as 4 to 72. This means that for every 4 D's, there are 72 A's.

We are also given that there are 1080 A's in the school this term.

To find the number of D's, we can set up a proportion using the ratio:

4 D's / 72 A's = X D's / 1080 A's

Cross-multiplying, we get:

4 * 1080 = 72 * X

Simplifying further:

4320 = 72X

Dividing both sides by 72:

X = 4320 / 72

X = 60

Therefore, there were 60 D's in the school.
