The ratio of savings to expenditure is 2:8 find the savings if the expenditure is 24,000​

Mathematics
1 answer:
WITCHER [35]2 years ago
6 0

Answer:

the savings is 6000

Step-by-step explanation:

We are told that the ratio of savings to expenditure is 2: 8, that is, that person saves 2 when he spends 8.

They tell us to find the savings when the cost is 24,000, so we are left with:

24000 * 2/8 = 6000

which means that when 24000 are spent the savings is 6000

please help if you know! lesson name: L 10.5: Using the Distributive Property here is the pic i don't understand
Andrei [34K]

Answer:

Area of the shaded region = 1.72r²

Step-by-step explanation:

Radius of the circle = r

Length of the rectangle = 4r

Width of the rectangle = 2r

Area of the circle = πr²

Area of the rectangle = Length × Width

= 4r × 2r

= 8r²

Area of the shaded region = Area of the rectangle - 2 × Area of the circle

= 8r² - 2 × πr²

= 8r² - 2πr²

= r²(8 - 2π)

= r²(8 - 2 × 3.14)

= r²(8 - 6.28)

= 1.72r²

What did i do wrong?
irakobra [83]

Answer:

27x +42+ 3x²

Step-by-step explanation:

so im learning this rn in class and what you do is FOIL

So its stands for

First

Outside

Inside

Last

(3x+6)(x+7)

(3x+6)(x+7) -- 3x² (if you have x times x it is x to the second power)

(3x+6)(x+7) -- 21x

(3x+6)(x+7) -- 6x

(3x+6)(x+7) -- 42

Now add 21x and 6x

27x +42+ 3x²

you must have added the 21 and 6 incorrectly.

Let t be time in seconds and let r(t) be the rate, in gallons per second, that water enters a reservoir: r(t)=700−40t. a) For 0≤
Flura [38]
What you don't want is the value of r(t) becoming negative. Surely that would represent water escaping the reservoir.

How big can (t) get before water actually starts escaping the reservoir?

Essentially, to figure this out r(t) would have to be equal to 0. 

700 - 40t = 0

40t=700

t=700/40=17.5

So the first answer is 17.5 seconds. After this amount of time has elapsed the reservoir will start to lose water as r(t) would become negative.

---------------

The reservoir had the least amount of water in it before it was being filled. That was when t=0. The volume of water in the reservoir wasn't negatively impacted as not enough water had escaped it during the 17.5 to 30 second period.
