What is (3x9-6+3\10)

1 answer:

4 0

The order of operations says:
P arentheses
E xponents
M ultiplication
D ivision
A ddition
S ubtraction

So first we will do 3 x 9 = 27. (27 - 6 + 3 / 10)
Next do 3/10 = .3. (27 - 6 + .3)
Then solve 27-6 = 21. (21 + .3)
Lastly do the last part! The answer is 21.3, hope this helps!

If a solution has 24g of sugar in 130ml of water, what is its concentration?

Jobisdone [24]

Answer: concentration = 15.58%

Step-by-step explanation:

Given: mass of sugar = 24 g = 24 ml [ ∵ 1 g = 1 ml]

Volume of solution = Quantity of water + quantity of solute

= 130 +24 ml

= 154 ml

Concentration = $\dfrac{mass\ of\ solute}{Volume\ of\ solution}\times100$

$=\dfrac{24}{154}\times 100\\\\\approx15.58\%$

Hence, the concentration =15.58%

(fg)-1(5)=g-1f-1(5)

larisa86 [58]

Answer:

f = g/ g+1

Step-by-step explanation:

Remove Parenthesis.

fg - 1 x 5 = g - 1 x f - 1 x 5

Cancel -1 x 5 on both sides.

fg = g - 1 x f

Simplify 1 x f to f.

fg = g - f

Add f to both sides.

fg + f = g

Factor out the common term f.

f (g + 1) = g

Divide both sides by g + 1

f = g/ g + 1

3. A carpenter is framing a window with wood trim where the length of the window is 6 and 2\3 feet. If the width of the window i

wel

We can see that window is in shape of rectangle. So the length of the required wood to frame window is equal to the perimeter of rectangle.

SO the length of rectangular window is $= 6 \frac{2}{3} = \frac{20}{3}$ feet.

Width of the rectangular window is = $7 \frac{3}{4} = \frac{31}{4}$ feet.

In general parameter of rectangle is = $2(l+b)$

So the parameter of window is = $2( \frac{20}{3} + \frac{31}{4}) = 2* \frac{(80+ 93)}{12} = 2* \frac{173}{12} = 28.834$

So the required length of wood to frame window is = 28.834 feet
