It’s B. Multiply the triangle and subtract the rectangle. 15.1 x 10.3 / 2 = 77.765. 2.8 x 6.5 = 18.2. 77.765-18.2= 59.565 = 59.6

Will give brainlisted whoever is correct first. please hurry.
kipiarov [429]

Answer:

32.33 <= m

Step-by-step explanation:

Since we are dealing with below sea level our initial starting point and max level will both be negative values, while our descending rate will also be negative because we are going down. Using the values provided we can create the following inequality...

-400 <= -12m - 12

Now we can solve the inequality to find the max number of minutes that the submarine can descend.

-400 <= -12m - 12   ... add 12 on both sides

-388 <= -12m   ... divide both sides by -12

32.33 <= m

Find the sum of 997 + 992 + 987 +...+ 257 +252
Vikentia [17]

Answer:

  93,675

Step-by-step explanation:

We see that the given sequence is an arithmetic sequence with first term 997, common difference -5, and last term 252.

The number of terms in the sequence (n) can be found from the formula for the n-th term:

  an = a1 +d(n -1)

  (an -an)/d +1 = n

  (252 -997)/(-5) +1 = n = 150

The sum of these terms is the average of the first and last terms, multiplied by the number of terms:

  S150 = (997 +252)/2·150 = 93,675

The sequence sum is 93,675.

I need to know how to do these
Allisa [31]

I'll do one, you can use it as a basis for your answer.

7x ^{2}    + 6 = 13

Subtract 6 from both sides to get X by itself.

7x ^{2}  = 7

Now we divide by 7 for both sides as well.

x {}^{2}  = 1

Now we find the square root of 1 to figure out X.

\sqrt{1}  = 1

Therefore, X=1.

my first answer in about a month. hope this helped.
