Hey there!
Surface area is for three dimension figures, and measures the area and how much space and as aforementioned area is in the object. This shape is a rectangular prism, so the surface area formula is:
2(lw+wh+lh)
Surface area is just an adding of all of the areas of the sides. It's times two because just the parentheses cover half the object. Plug in values:
A = 2(6*17 + 6*9 + 17*9) =
2(6)(17) + 2(6)(9) + 2(17)(9) =
204 + 108 + 306 =
618
Hope this helps!
Answer:
2.a)11.355 b)0.94625
3. divide 6 by 4
4. 0.8kg, 800g
Step-by-step explanation:
To convert one measurement to another you need to set it up so that the old measurement gets cancelled out when you multiply the conversion ratio.
2a)
the gallons on top and bottom get cancelled out leaving you with the measurement that you want
2b) ![\frac{1quart}{1} *\frac{1 gallon}{4 quarts} *\frac{3.785 milliliters}{1 gallon} = 0.94625 milliliters](https://tex.z-dn.net/?f=%5Cfrac%7B1quart%7D%7B1%7D%20%2A%5Cfrac%7B1%20gallon%7D%7B4%20quarts%7D%20%2A%5Cfrac%7B3.785%20milliliters%7D%7B1%20gallon%7D%20%3D%200.94625%20milliliters)
3) ![\frac{x}{y} \frac{6 quarts}{1} *\frac{1 gallon}{4 quarts} = 1.5 gallons](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D%20%5Cfrac%7B6%20quarts%7D%7B1%7D%20%2A%5Cfrac%7B1%20gallon%7D%7B4%20quarts%7D%20%3D%201.5%20gallons)
4) ![\frac{28 ounces}{1} *\frac{1 kilogram}{35 ounces} = 0.8 kilograms](https://tex.z-dn.net/?f=%5Cfrac%7B28%20ounces%7D%7B1%7D%20%2A%5Cfrac%7B1%20kilogram%7D%7B35%20ounces%7D%20%3D%200.8%20kilograms)
![\frac{0.8 kilograms}{1} *\frac{1000 grams}{1 kilogram} = 800 grams](https://tex.z-dn.net/?f=%5Cfrac%7B0.8%20kilograms%7D%7B1%7D%20%2A%5Cfrac%7B1000%20grams%7D%7B1%20kilogram%7D%20%3D%20800%20grams)
Answer:
(-3, 7)
Step-by-step explanation:
ok so first take the square root of both sides, so you get (x-2)=5, since the square root gets rid of the power, and the square root of 25, is 5, and since we did a square root, we also have to do the - + thing, so the equation really is now x-2=(+-)5
subtract 2 from both sides, and you get x=(+-)5+2
Solving for x we get -5+2=-3
and also
5+2=7 since there was a positive, and a negative 5.
therefore x would equal (-3, 7)

10-6=4
You cannot use 6-10 because that would give you a negative answer.
Answer:
In step 1 subtraction property is used and in step 2 division property is used.
Explanation:
We have the equation 2x + 6 = 22
Step 1
The subtraction property of equality tells us that subtracting the same number to each side of an equation gives us an equivalent equation
So subtracting 6 from both sides
2x + 6 - 6 = 22 - 6
2x = 16
Step 2
The division property of equality tells us that you can divide each side of an equation with the same nonzero number to produce an equivalent equation
So dividing each side by 2.
![\frac{2x}{2} =\frac{16}{2} \\ \\ x=8](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7B2%7D%20%3D%5Cfrac%7B16%7D%7B2%7D%20%5C%5C%20%5C%5C%20x%3D8)
