I really need help, struggling. Question is in image. ​

Mathematics
1 answer:
Dominik [7]2 years ago
5 0

Answer:

164

Step-by-step explanation:

Checkpoint 2= -187

Checkpoint 1= -23

The negatives mean how much lower they are from the surface.

To find "how much lower," we need to subtract -23 from -187.

-187-(-23) is the same as -187+23 (2 negatives=1 positive)

-187+23= -164.

However, it's not negative in the answer because by asking how much lower, we don't need to have a negative. "How much lower" is a distance, and a distance is always positive.

Use the arithmetic progression formula to find the sum of integers from 75 to 100.75,76,77....99,100.​
Sophie [7]

Answer:

The sum is 2275

Step-by-step explanation:

Given

75,76,77....99,100

Required

The sum

Using arithmetic progression, we have:

S_n = \frac{n}{2}(T_1 + T_n)

Where:

T_1 = 75 --- first term

T_n = 100 --- last term

n = T_n - T_1 + 1

n = 100 - 75 + 1 = 26

So, we have:

S_n = \frac{n}{2}(T_1 + T_n)

S_n = \frac{26}{2}*(75 + 100)

S_n = 13*175

S_n = 2275
