The sum of two numbers is 49 and the difference between these two numbers is 9. What are these two numbers?​Shown working out pl
8_murik_8 [283]

Let numbers be x and y

ATQ

  • x+y=49---(1)

  • x-y=9---(2)

Adding both

\\ \sf\longmapsto 2x=58

\\ \sf\longmapsto x=\dfrac{58}{2}

\\ \sf\longmapsto x=29

Now putting value in eq(2)

\\ \sf\longmapsto x-y=9

\\ \sf\longmapsto 29-9=y

\\ \sf\longmapsto y=20

What that two numbers when multiplied give 600 and when added give 59 ​
ozzi

Answer:

Step-by-step explanation:

Let the 2 numbers be x and y

From the problem we have that

x * y = 600 and x + y = 59

From x + y = 59 -> x = 59 - y

Plug x = 59 - y to x * y = 600 we have

(59 - y) * y = 600

-> 59y - y^2 = 600

-> -y^2 + 59y - 600 = 0

-> y = (59 - \sqrt{1081})/2 or (59 + \sqrt{1081})/2

Then we could plug the answers in and find x because x = 59 - y

Three co-workers are packing books in a storage bin. The bin is 4 feet high, 9 feet long, and 11 feet wide. If 6 books fill 1 cu
evablogger [386]

Alright, lets get started.

Height of the bin = 4 ft

Length of the bin = 9 ft

Width of the bin = 11 ft

Volume of the bin = L*W*H

Volume V = 9*11*4

Volume V= 396 cubic feet

6 books fiils 1 cubic feet

or

1 cubic feet is filled by = 6 books

So, 396 cubic feet is filles by = 396 * 6

So, 396 cubic feet is filles by =2376 books

It means 2376 books will fit in the storage bin. : Answer

Hope it will help :)

Tom brought 7/8 gallons of water to a party and his friends drank2/3 of it. How many gallons of water did they drink?
natka813 [3]
In plain and short, what's 2/3 of 7/8?  well, is just their product.

\bf \cfrac{7}{8}\cdot \cfrac{2}{3}\implies \cfrac{7\cdot 2}{8\cdot 3}\implies \cfrac{14}{24}\implies \stackrel{simplified}{\cfrac{7}{12}}

A cylinder has a radius of 4x + 2 and a height of 5x + 4. Which polynomial in standard form best describes the total volume of t
Olenka [21]
Area of the base = pi*(4x+2)^2 = pi*(16x^2 +16x +4)

volume of cylinder = pi*r^2 *h 

V = pi *(16x^2 +16x +4)(5x+4) = pi*(80x^3 +80x^2 +20x +64x^2 +64x +16) = 

= pi*(80x^3 +144x^2 +84x +16)

than we consider it without pi so result choice A. is right sure 

hope helped
