Answer: X would equal -8

Step-by-step explanation: Starting off, you would cross multiply, so 414 times 1 = (x-10) times -23. It's similar to the one I answered before, just with different numbers. 414 = -23 (x-10). After that, distribute to get: 414 = -23x +230. Then subtract 230 from both sides and divide by -23 to get x. Hope that helps.

Evaluation problem please help

Darya [45]

Ok so what you want to do is multiply 2 tines 4 which is 8 then multiply 723 8 times into the calculator or just press the button next to the button on the left 8 times ok then do that again for 723^5 power so whatever product you get for the both of them multiply them then divide whatever product you get on to top to the bottom oops sorry that is the long way so basically 4 times 2 is 8 now that plus 5 = 13 so now on the top half we have 723^13 and on the bottom it is the same thing so divide your answer is 1

vladimir1956 [14]

Answer:

Part A: Profit = 400 + 70 s, Part B : $3900

Step-by-step explanation:

Part A:

We know that the expression is: 0.2 ( 2000 + 350 s ). Using the distributive property :

Profit = 0.2 · 2000 + 0.2 · 350 s = 400 + 70 s

Part B :

The company's yearly profit when: s = 50 ( the total number of students )

P ( 50 ) = 400 + 70 · 50 = 400 + 3500 = $3900

The diagram below gives the dimensions of a swimming pool. 18 ft , 20ft, 36ft (c) What is the total area of the swimming pool? E

WARRIOR [948]

The picture in the attached figure

Part 1) What is the total area of the swimming pool?

we know that
area of the swimming pool=area rectangle-area semi circle

area rectangle=20*36-----> 720 ft²

area semicircle=pi*r²/2
r=18/2----> 9 ft
area semicircle=pi*9²/2----> 127.17 ft²

area of the swimming pool=720 ft²-127.17 ft²----> 592.83 ft²

the answer Part 1) is
The area of the swimming pool is 592.83 ft²

Part 2) What is the perimeter of the swimming pool?

perimeter of the swimming pool=perimeter of rectangle-18 ft+perimeter semi circle
perimeter of rectangle=2*[20+36]---> 112 ft

perimeter semi circle=2*pi*r/2----> pi*r
r=9 ft
perimeter semi circle=pi*9----> 28.26 ft
so
perimeter of the swimming pool=112 ft-18 ft+28.26 ft----> 122.26 ft

the answer Part 2) is
122.26 ft
