Step-by-step explanation:
easy to look up : mili stands for 1/1000
so,
500 ml are 500/1000 liters.
25 ml are 25/1000 liters (a tiny glass).
and 1 Iiter is of course, 1000/1000 liters (1000 ml).
4 liters 500 ml are then
4×1000/1000 + 500/1000 = 4500/1000 l = 4500 ml.
how many glasses of 25 ml can be filled with that ?
this is the same question as into how many parts of 25 can 4500 be split ? or, how often does 25 fit into 4500 ?
all this is done by division :
4500 / 25 = 180
so, 180 of such glasses can be filled.
Find the perimeter and area of the figure pictured below
Answer:
Perimeter = 45.8m
Area = 63.61m²
The perimeter and area of the figure are 38 m and 63.61 m² respectively
Given data:
The figure consists of 2 rectangles.
The dimensions of the first rectangle is L = 9.2 m and W = 3.9 m.
The dimensions of the second rectangle is L = 5.9 m and W = 4.7 m.
So, the total perimeter of the figure is represented as P.
The value of P = 9.2 + 3.9 + 9.8 + 4.7 + ( 9.2 - 4.7 ) + ( 9.8 - 3.9 )
P = 27.6 + 4.5 + 5.9
P = 38 m
The area of the figure is represented as A.
A = ( 9.2 x 3.9 ) + ( 5.9 x 4.7 )
A = 35.88 m² + 27.73 m²
A = 63.61 m²
Hence , the area of the rectangular figure is A = 63.61 m².

Find the approximate area of the shaded region. Use 3.14 for pi
The area of the shaded region of the rectangle is approximately 573.92 ft².
What is the area of the shaded region?The figure in the image composes of a semi-circle inscribed inside of a rectangle.
To determine the area of the shaded region, we simply subtract the area of the semi-circle from the area of the rectangle.
Area of rectangle = length × width
Area of semi-circle = 1/2 × πr²
Hence:
Area of shaded region = ( length × width ) - ( 1/2 × πr² )
From the diagram;
Length of the rectangle = 40ft
Width = 20ft
Radius of the semi-circle = 12ft
Plug these values into the above formula:
Area of shaded region = ( 40 × 20 ) - ( 1/2 × 3.14 × 12² )
Area of shaded region = ( 800 ) - ( 1/2 × 3.14 × 144 )
Area of shaded region = ( 800 ) - ( 226.08 )
Area of shaded region = 573.92 ft²
Therefore, the shaded region measures 573.92 ft².

The numeric value of the exponential expression in this problem is given by the following option:
A. 2^12.
How to obtain the numeric value of the exponential expression?The exponential expression for this problem is defined as follows:
8^x/2^y.
8 is the third power of 2, hence:
8 = 2^3.
When a term is elevated to two of it's powers, the powers are multiplied, hence:
(2^3)^x = 2^(3x).
Meaning that the exponential expression is then written as follows:
8^x/2^y = 2^(3x)/2^y.
When two terms of the same base and different exponents are divided, we keep the base and subtract the exponents, hence the expression is given as follows:
2^(3x)/2^y = 2^(3x - y).
As stated in the problem, the numeric value of the expression 3x - y is given as follows:
3x - y = 12.
Hence the entire expression is simplified as follows:
2^(3x - y) = 2^12.
Meaning that the correct option is given by option A.

If
f(x) = 2x² – 5
and
g(x) = 5x + 7
Find
g(f(x)) = 10x² + [? ]
Answer:
The missing term in the output of the function \(g(f(x))\) is -18.
\(g(f(x))=10x^2-18\)
Step-by-step explanation:
Function CompositionIn mathematics, function composition is a term that encompasses a relationship between two functions wherein the output of one function is used as the input for another function. This relationship combines two functions to form a single function, known as a composite function. For future reference, function composition may also be denoted by a small circle, see below:
\((g\circ f)(x)=g(f(x))\)
In the given problem, we must evaluate the composite function \(g(f(x))\) / \((g\circ f)(x)\) to identify the unknown term.
With composite functions, we begin evaluating from the inside. To evaluate \(g(f(x))\), we must substitute the output of the function \(f(x)\) (given as the expression \(2x^2-5\)) as the input (\(x\)) for the function \(g(x)\):
\(g(f(x))=g(2x^2-5)\)
Now, using \(f(x)\) as the input (\(x\)) for the function \(g(x)\) (given as the expression \(5x+7\)), we can substitute \(2x^2-5\) into the output for the function \(g(x)\):
\(g(f(x))= 5(2x^2-5)+7\)
From here, we can go ahead and distribute the 5:
\(g(f(x))=10x^2-25+7\)
Combine like terms:
\(g(f(x))=10x^2-18\)
With the composite function evaluated, we can identify our missing term as \(-18\).

Step-by-step explanation:
1 dollar bill is 6.14 inches long 2.61 wide and 0.00043 thick. If you had 1 billion in 100 dollar bills the the number of bills would be
The number of 100 dollar bills in one billion dollars is 10 million hundreds or 70,900 hundred dollar bills.
To find the number of 100 dollar bills in one billion dollars, we can use the following steps:
First, we need to find the value of one billion dollars in terms of hundreds. Since each hundred dollar bill has a value of $100,
we can divide one billion by 100 to get the number of hundreds
\(:$$\frac{1\text{ billion}}{100}=10\text{ million}$$\)
So one billion dollars is equal to 10 million hundreds.
Now we need to find the volume of one hundred dollar bill. To do this, we multiply its length, width, and thickness:\($$6.14 \text{ in} \times 2.61 \text{ in} \times 0.00043 \text{ in}=0.00709 \text{ in}^3$$\)
The volume of one hundred dollar bill is approximately 0.00709 cubic inches.
Finally, we need to find the total volume of 10 million hundreds:\($$0.00709 \text{ in}^3 \times 10,000,000=70,900 \text{ in}^3$$\)
Therefore, the total volume of 10 million hundred dollar bills is approximately 70,900 cubic inches.10 million hundreds or 70,900 hundred dollar bills.

Find the fist 4 terms of a geometric series with first term of 8 and the sum to infinity of 12
Step-by-step explanation:
the sum of an infinite geriatric series with |r| < 1 is
s = a1/ (1 - r)
in our case we have
a1 = 8
12 = 8/(1 - r)
12(1 - r) = 8
1 - r = 8/12 = 2/3
-r = -1/3
r = 1/3
so, the first 4 terms (I added a5 too, just in case your teacher meant the NEXT 4 terms) are
a1 = 8
a2 = a1 × 1/3 = 8/3
a3 = a2 × 1/3 = 8/9
a4 = a3 × 1/3 = 8/27
a5 = a4 × 1/3 = 8/81
...
Answer:
\(8,\quad \dfrac{8}{3},\quad \dfrac{8}{9},\quad\dfrac{8}{27}\)
Step-by-step explanation:
Sum to infinity of a geometric series:
\(S_\infty=\dfrac{a}{1-r} \quad \textsf{for }|r| < 1\)
Given:
\(a\) = 8\(S_\infty\) = 12Substitute given values into the formula and solve for \(r\):
\(\implies 12=\dfrac{8}{1-r}\)
\(\implies 1-r=\dfrac{8}{12}\)
\(\implies r=1-\dfrac{8}{12}\)
\(\implies r=\dfrac{1}{3}\)
General form of a geometric sequence: \(a_n=ar^{n-1}\)
(where a is the first term and r is the common ratio)
Substitute the found values of \(a\) and \(r\):
\(\implies a_n=8\left(\dfrac{1}{3}\right)r^{n-1}\)
The first 4 terms:
\(\implies a_1=8\left(\dfrac{1}{3}\right)r^0=8\)
\(\implies a_2=8\left(\dfrac{1}{3}\right)r^1=\dfrac{8}{3}\)
\(\implies a_3=8\left(\dfrac{1}{3}\right)r^2=\dfrac{8}{9}\)
\(\implies a_4=8\left(\dfrac{1}{3}\right)r^3=\dfrac{8}{27}\)

Step-by-step explanation:
First we want to plug it into the \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\). This gets us 6-2/7-(-1) which solves to 4/8 which simplifies to 1/2. This gives us the slope. Now, when using slope intercept form y = mx + b, we can plug our newly found slope in for m and get y = 1/2x + b. To find b plug in any point on the line into the equation, I chose (7,6) because we are given that, and both numbers are positive. Now plug those in for x and y. 6 = 1/2(7).

Take domain:{-4,-2,0,2,4}
Put x=-4 in the function then we get
f(x)=40
Put x= -2 then we get
f(x)=20
Put x=0 then we get
f(x)=0
Put x=2 then we get
f(x)=-20
Put x=4 then we get
