Step-by-step explanation:

It is a right triangle, so it can be solved with the Pythagorean Theorem.

Answer:

Step-by-step explanation:

Length of PR = 40 units

Length of RQ = 70 units

ΔPQR is a  right angle. So, to fin the length of PQ, use Pythagorean theorem

hypotenuse² = base² + altitude²

PQ² = PR² + RQ²

       = 40² + 70²

       = 1600 + 4900

       = 6500

PQ = √6500 = 80.62 units

PQ = 80.62 units

10x+40

Step-by-step explanation:

To solve you must follow these steps:

1. Multiply the outside (5) by the first number on the inside (2x) and you get 10x

2. Multiply the outside (5) by the second number on the inside of the parenthesis (8) and you get 40

3. You are left with 10x and 40, so your answer is 10x+40

Hope this makes sense, have a wonderful day!

answer: 10x+40

This is because you will divide 5 by 2x and the 5 by 8 so once you divided your answer should look like 10x+40

Find the value of x and m∠HKL.

Answers

Answer:

x = 25 degrees   ∠HKL = 102 degrees

Step-by-step explanation:

The whole thing equals 180, since it is a straight angle

The value of HKL is 180 - 78 = 102

So that means 4x + 2 = 102

Subtract 2 from both sides:

4x = 100

Divide both sides by 4:

Option 3 3 1/8x - 6 3/10

Step-by-step explanation:

(3 1/2x - 4 1/10) - (3/8x + 2 1/5)

Divide it into parts:

(3 1/2x - 3/8x) + (-4 1/10 - 2 1/5)

3 1/2x - 3/8x = 3 4/8x - 3/8x = 3 1/8x

ΔPQR has angle measurements of 80°, 50°, and 50°. What kind of triangle is ΔPQR?

Answers

Answer:

Isosceles Triangle; Acute Triangle

Step-by-step explanation:

Review your definitions of the different types of triangles:

acute triangle- a triangle that has three acute (less than 90 degrees) angles

obtuse triangle- a triangle that has an obtuse (greater than 90 degrees) angle.

right triangle- a triangle that had one right (90 degrees) angles

isosceles triangle- a triangle with two congruent sides and one unique side and angle.

equilateral triangle-  a triangle with three congruent sides and three congruent angles.

scalene triangle- a triangle with no congruent sides and no congruent angles.

With these definitions, we can classify ΔPQR as an isosceles acute triangle.

A supermarket operator must decide whether to build a medium size supermarket or a large supermarket at a new location. Demand at the location can be either average or favourable with estimated probabilities to be 0.35 and 0.65 respectively. If demand is favorable, the store manager may choose to maintain the current size or to expand. The net present value of profits is $623,000 if the firm chooses not to expand. However, if the firm chooses to expand, there is a 75% chance that the net present value of the returns will be 330,000 and 25% chance the estimated net present value of profits will be $610,000. If a medium size supermarket is built and demand is average, there is no reason to expand and the net present value of the profits Is $600,000. However, if a large supermarket is built and the demand turns out to be average, the choice is to do nothing with a net present value of $100,000 or to stimulate demand through local advertising. The response to advertising can be either unfavorable with a probability of 0.2 or faverable with a probability of 0.8. If the response to advertising is unfavorable the net present value of the profit is ($20,000). However, if the response to advertising is favourable,then the net present vale of the profits in $320,000. Finally, if the large plant is built and the demand happens to be high the net present value of the profits is $650.000.
