I am not 100 percent sure but it's what I got
Answer:
E) 15/64
Step-by-step explanation:
To compare the numbers, it works best to express them all using a common denominator. One possibility is 1600, another is 1,000,000.
9/40 = 360/1600
5/16 = 500/1600
9/32 = 450/1600
0.28 = 448/1600
15/64 = 375/1600
The number we're comparing to is 0.25 = 400/1600, so we want to find the closest number to 400 in the set ...
... {360, 500, 450, 448, 375}.
The magnitude of the differences of these numbers from 400 is ...
... {40, 100, 50, 48, 25}.
Clearly, the last number, 15/64 = 375/1600 has the smallest difference from 0.25.
Answer:
Density in decimal can be written as 0.0001429 gram per liter
Step-by-step explanation:
We have given density of oxygen is
We have to convert this density in decimal form
We know that can be written as
So
So density in decimal can be written as 0.0001429 gram per liter
Answer:
The expression that represents the perimeter of the rectangle is "12*x + 18", where "x" is the length of the rectangle.
Step-by-step explanation:
In order to solve this question we were given an expression that relates both dimensions of the rectangle. This expression in a mathematical form where "x" is the length and "y" is the width is shown bellow:
y = 9 + 5*x
The perimeter of a rectangle is given by:
perimeter = 2*length + 2*width
perimeter = 2*x + 2*(9+5*x)
perimeter = 2*x + 18 + 10*x
perimeter = 12*x + 18
The expression that represents the perimeter of the rectangle is "12*x + 18", where "x" is the length of the rectangle.
The answer to this question would be: <span>y=5x-1
To solve this question, you need to see what the value of Y when X=0. In this case, when X=0 the Y=-1
That means if the function is Y= AX+ C then the C would be:
Y= AX +C
-1= </span>A(0) +C
<span>C= -1
If you put the second equation where X=1 and Y=4 then
</span>Y= AX +C
4= A(1) -1
4= a-1
a=5
The answer would be y=5x-1
