Answer:
A. 675 units²
Step-by-step explanation:
The formula for the surface area of a square pyramid is ...
A = s(s +2h)
where s is the side length of the base, and h is the slant height of a face.
__
<h3>use the formula</h3>
The given pyramid has s=15 and h=15, so the surface area is ...
A = (15)(15 +2×15) = 15(45) = 675 . . . square units
The first thing we must do for this case is to define a variable.
We have then:
x: number of years before the Russo-Japanese conflict began
We write now the inequality that models the problem.
We know that the conflict began in the year 1904, therefore, all the previous years are given by:
x <1904
Answer:
an inequality in terms of x and 1904 that is true only for values of x that represent years before the start of the Russo-Japanese War is:
x <1904
If you would like to solve (40 * x * 64 * y) / (5 * x * 8 * y), you can calculate this using the following steps:
(40 * x * 64 * y) / (5 * x * 8 * y<span>) = 8 * 8 = 64

The correct result would be 64.
Answer:
x = 11.4
Step-by-step explanation:
14.12 = 
( 3.6x - 12.8 )
Rewrite so that the equation is entirely in decimals;
14.12 = 0.5( 3.6x - 12.8 )
Distribute;
14.12 = 1.8x - 6.4
Inverse operations;
14.12 = 1.8x - 6.4
+6.4 +6.4
20.52 = 1.8x
/1.8 /1.8
11.4 = x
The value when 34 is divided by 5323 is 0.00639.
<h3>What is division?</h3>
It should be noted that division simply means the opposite of multiplication. It represents the way numbers are combined in order to make new numbers.
The steps include:
1: Take the dividend's first digit starting from the left in step one. Verify if this digit exceeds or is equal to the divisor.
2. Next, divide it by the divisor, and write the result as the quotient on top.
3. Subtract the outcome from the digit, and then put the difference below.
4: Decrease the dividend's subsequent digit (if present).
5: Carry out Step 4 again.
In this case, 34 divided 5323 will be 0.00639. It should be noted that this illustrates a decimal.
