One liter of interior paint covers 100 square feet. How many gallons of paint does it take to cover 800 square meters of walls?
By doing some changes of units, we can see that we will need 22.61 gallons of paint to cover 800 square meters.
How many gallons does it take to cover 800 square meters of walls?
We know that with one liter of interior paint we can cover 100 square feet.
Remember the relation between square feet and square meeters:
1ft^2 = 0.092 m^2
Then with one liter we can cover:
100ft^2 = 100*0.092 m^2 = 9.2 m^2
So the number of liters of paint that we need to cover the 800 m^2 is given by the quotient:
L = 800m^2/9.2m^2 = 86.96
We need 86.96 liters of paint, and the relation between liters and gallons is:
1 L = 0.26 gal
Then we need:
86.96 L = 86.96*(0.26 gal) = 22.61 gal
We will need 22.61 gallons of paint to cover 800 square meters.

Random means by chance.
O True
O False
Answer:
True
Step-by-step explanation:
Because you never expect when something may show up once your doing something and forget about what you lost a while back. Sometimes it just pops up and we're like, "Oh that's where it was".
Can't say true or false because both can be answers in different cases, mathematically speaking you can select one thing from a set of similar things having similar chance to be selected. and again you can also select one thing at random from a set of things having different chance of being selected. in my perspective:)
and maybe the question has more chance to be false because if a statement is false at least in one case it is false.
Graph the line with slope
-1/2
passing through the point (-1,-4)
Equation of the line with slope -1/2 passing through the point (-1,-4) is x + 2y = -9
Given,
the slope of the line = -1/2
the line passes through the point (-1,-4)
=> s = -1 and t = -4
The following equation can be used to find the line's equation:
( y - t ) = slope ( x - s )
We get by substituting the values in the equation
=> y + 4 = - 1/2 * ( x + 1 )
=> x + 2y = -1 - 8
=> x + 2y = -9
Therefore, by using the formula for equation of line, we get the equation of the line with slope -1/2 passing through the point (-1,-4) as x + 2y = -9

I think you are supposed to add the the numbers in that row and if it's more that 18 and less that 37 that's the answer. exapmle:

Add those together and get 27. 27 is less than 37 and more that 18 so it would be one of the answers.

Answer:-26
Step-by-step explanation:
Answer:-14-12=-26
Step-by-step explanation: PEMDAS. You do the first parentheses which is 7-21, which will get you -14. Then you do the second parentheses, 4+8. That will get you 12. Then since there’s no multiplication/division, you go to addition/subtraction and since there’s a subtraction symbol in between the parentheses, that’s what you do. -14-12 which will get you -26.
Hope this helps!

Which table represents y as a function of x?
[tex]{ \qquad\qquad\huge\underline{{\sf Answer}}} [/tex]
An equation represents a represents only when there is a unique value of x for every value of y. when it represents u as a function of x.
i.e if we draw lines parallel to y axis and it cuts the curve two or more than two times at a particular value of x then it doesn't represent a function at all.
And as we can see in the given tables,
1.) 12.23 is the value of x for both 5.4 and 6.4
2.) 0.31 is the value of x for both 55 and 59
4.) 20 is the value of x for both 245 and 255
So, the only table representing y as a function of x is table 3.

The equivalent expression of (10⁻² . 4⁵)⁻² is 10⁴ / 4¹⁰
How to find equivalent expression?We have to find the expression that is equivalent to the expression below:
(10⁻² . 4⁵)⁻².
Therefore, using the law of indices,
[tex](x^{a} )^{b} = x^{ab}[/tex]
Hence, let's find the equivalent expression by applying the laws of indices.
(10⁻² . 4⁵)⁻² = 10⁴ . 4⁻¹⁰
Also, applying the law of indices,

Hunter measured the middle school and made a scale drawing. The scale he used was 1 inch : 10 feet. The gym is 7 inches wide in the drawing. How wide is the actual gym?
Answer:
70 ft
Step-by-step explanation:
You want the actual width of a gym that is represented as 7 inches on a drawing with a scale of 1 in : 10 ft.
Scale factorEach inch represents 10 feet, so 7 inches will represent ...
7 × 10 ft = 70 ft
The gym is 70 ft wide.
__
Additional comment
You can also write and solve an equation that shows the measures are proportional:
actual width / drawing width = (10 ft) / (1 in) = (gym width) / (7 in)
Multiplying both sides of this proportion by 7 in, we have ...
gym width = (7 in) × (10 ft)/(1 in) = 7 × 10 ft = 70 ft

Write
17/100
as a decimal number.
Answer: 0.17
Step-by-step explanation:
Plug the equation into a calculator (17 divided by 100).
You can also think of the problem like this; move both decimal places to the left twice since, in 100, there are two 0's.
17 -> 0.17
100 -> 1
This can also work with 17 and 1000, but you would have to move the decimal place three times.
17 -> 0.017
1000 -> 1

Step-by-step explanation:
Given quadrilateral ABCD with diagonal BD forming triangles ABD and BCD, and angles A=90°, C=52°, ADB=35°, and CBD=52°, you want the length of CD to 3 significant figures.
Law of SinesThe law of sines tells you the relation between sides and opposite angles is ...
a/sin(A) = b/sin(B) = c/sin(C)
This lets us write two proportions that can be solved for the measure of CD.
In triangle ABD:
BD/sin(A) = AB/sin(D)
BD = AB·sin(90°)/sin(35°) = 12 cm/sin(35°) ≈ 20.921 cm
In triangle BCD:
CD/sin(B) = BD/sin(C)
CD = BD·sin(B)/sin(C) = 20.921 cm·sin(102°)/sin(52°) ≈ 25.969 cm
The length of CD is about 26.0 cm.
