Using mathematical operations, the population of Alaska in 2050 will be 8,99,500.

<h3>What are mathematical operations?</h3>

An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value.
The operation's arity is determined by the number of operands.
A mathematical action is called an operation. Mathematical operations include addition, subtraction, multiplication, division, and finding the root.

So, the population in 2050:

Population increases from 2000 to 2020:
733,000 - 622,000 = 1,11,000
Population change in 20 years = 1,11,000
In 10 years = 1,11,000/2 = 55,500

So, poulation in 5050:

2020 (20 years) ⇒ 2040 (00 years) ⇒2050
= 733,000 + 1,11,000 + 55,500
= 8,99,500

Therefore, using mathematical operations, the population of Alaska in 2050 will be 8,99,500.

Use △XYZ, in which ∠X is a right angle and tanY=815.

Neporo4naja [7]

Answer:

8/17

Step-by-step explanation:

The correct and complete question is:

<em>Use △XYZ, in which ∠X is a right angle and tanY=8/15. What is the ratio for sinY?</em>

From definition:

tan(Y) = opposite/adjacent

From the graph and the question:

tan(Y) = XZ/XY = 8/15

Then:

XZ = 8 and XY = 15. Using pytaghorean theorem:

XZ² + XY² = YZ²

8² + 15² = YZ²

√289 = YZ

17 = YZ

From definition:

sin(Y) = opposite/hypotenuse

From the graph:

sin(Y) = XZ/YZ

sin(Y)= 8/17

You are a real estate agent with ABC Real Estate company. You help sell a home for $155,000. The total commission is 6.5%. Your

gtnhenbr [62]

Answer:

$3,929.25.

Step-by-step explanation:

First, calculate the total commission. That's found by multiplying the selling price ($155,000) by 0.065. The result: The total commission is $10,075.

Your company receives 60% of that. So we multiply $10,075 by 0.60, obtaining $6,045.

Your share of the commission is 65% of that, so we multiply $6,045 by 0.65:

0.65($6,045) = $3,929.25.

Your personal share of the commission is thus $3,929.25.

A helicopter is hovering 110 feet in the air over a landing pad. If a man sees the helecopter at an angle of elevation of 29°, w

Pavel [41]

See the attached figure to better understand the problem

we know that

tan 29°=AC/CB--------> CB=AC/tan 29°
AC=110 ft
CB--------> <span>how far the man is from the helicopter landing pad
</span>so
CB=AC/tan 29°----------> CB=110/ tan 29°----------> CB=198.45 ft

the answer is
the man is 198.45 ft from the helicopter landing pad
