what is the difference between 903.55 and 87.7
Answer:903.55
Step-by-step explanation:
The difference between the values 903.55 and 87.7 can be obtained using the subtraction operation on both values. Hence, the value of the difference is 815.85
Given the values :
903.55 and 87.7To obtain the difference, we use the subtraction operation thus :
903.55 - 87.7 = 815.85Therefore, the difference between 903.55 and 87.7 obtained by subtracting the two values from each other is 815.85

Write a linear function f with f (5) = -1 and f(0) = -5.
f(x)=____
Answer:
We conclude that the equation of a linear function with f (5) = -1 and f(0) = -5 will be:
f(x) = 4/5x - 5Step-by-step explanation:
Given
f(5) = -1f(0) = -5f(5) = -1 means at x = 5, y = -1
Hence, the point (5, -1) lies on the line function.
f(0) = -5 means at x = 0, y = -5
Hence, the point (0, -5) lies on the line function.
Thus, the two points on the linear line function graph are:
(5, -1)(0, -5)Finding the slope between the points (5, -1) and (0, -5)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(0,\:-5\right)[/tex]
[tex]m=\frac{-5-\left(-1\right)}{0-5}[/tex]
[tex]m=\frac{4}{5}[/tex]
The slope-intercept form of the linear line function
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
We have already determined the slope which is: m = 4/5
We know the y-intercept can be determined by setting x = 0 and solving for y.
Thus, the point (0, -5) represents the y-intercept b = -5.
Now, substituting m = 4/5 and b = -5 in the slope-intercept form
[tex]y = mx+b[/tex]
y = 4/5x + (-5)
y = 4/5x - 5
Therefore, we conclude that the equation of a linear function with f (5) = -1 and f(0) = -5 will be:
f(x) = 4/5x - 5Find the area of the figure. Use 3.14 for it.

Find the annual infiltration rate for the nearest 10th of a percent of a gallon of milk that increases the value from $1.51 to $2.03 over a period of seven years.
Answer:
7.429 cents
Step-by-step explanation:
Given that:
Price change = $1.51 to $2.03
Period of time = 7 years
Therefore, the annual inflation rate :
Difference in price / number of years
($2.03 - $1.51) / 7
$0.52 / 7
= 0.0742857 per year
= 0.0742857 * 100 (about 7.429 cents per year)

Which point is located at 2/4 on the number line??
Answer:
on C
Step-by-step explanation:
The point K is located at 2/4.
What is fraction?"It is a number expressed as a quotient, in which a numerator is divided by a denominator."
For given example,
We have been given a fraction 2/4.
We simplify given fraction 2/4 as
2/4
= 1/2
=0.5
Also, the midpoint of 0 and 1 is,
(0 + 1)/2 = 0.5
In the given graph the midpoint of 0 and 1 is denoted by K
Therefore, the point K is located at 2/4.

No these triangles are not similar.
Step-by-step explanation:
Given Information on First triangle :
Base = 3
Height = 8
Given information on Second triangle :
Base = 4
Height = 10
Area of a Right Angle triangle :
[tex] \frac{base \times height}{2} [/tex]
Area of First triangle :
[tex] \frac{3 \times 8}{2} = \frac{24}{2} \\ \\ = 12[/tex]
Area of Second triangle :
[tex] \frac{4 \times 10}{2} = \frac{40}{2} = 20[/tex]
Their Ratio :
[tex]12:20 = \frac{12}{20} \\ = \frac{3}{5} [/tex]

f(1)=2
f(n+1) = f(n)+4
What is f(10)?
9514 1404 393
Answer:
38
Step-by-step explanation:
The recursion relation describes an arithmetic sequence with a first term of 2 and a common difference of 4. The explicit formula for the n-th term of the sequence is ...
f(n) = f(1) +d(n -1) . . . . . for first term f(1) and difference d
f(n) = 2 +4(n -1) = 4n -2
Then the 10th term is ...
f(10) = 4(10) -2
f(10) = 38
If each soda sells for $2.50, what is the expected daily total dollar amount taken in by the vendor from the sale of sodas?
Answer:
$34.38
Step-by-step explanation:
Y: A random variable that indicates the amount of money that the seller will receive.
p=2,50$
if x=0 → y=0.2,50=0$
if x=5 → y=5.2,50 = 12,5 $
if x=10 → y=10.2,50= 25$
if x=15 → y=15.2,50= 37,5$
if x=20 → y=20.2,50= 50 $
if x=25 → y=25.2,50= 62,5$
Y= { 0$ ; 12,5$ ; 25$ ; 37,5$ ; 50$ ; 62,5$ }
E(Y)= ∑Y.P(Y)
= 0.P(0)+12,5.P(12,5)+ 25.P(25)+ 37,5.P(37,5)+ 50.P(50)+ 62,5.P(62,5)
= 0.0,01+ 12,5.0,15+ 25.0,25+ 37,5.0,3+ 50.0,25+ 62,5.0,04
= 0 + 1,875 + 6,25 + 11,25 + 12,5 + 2,5
= 34,38$ expected value of the amount of money the seller receives.

Step-by-step explanation:
An architect builds a model of a park in the shape of a rectangle. The model is 40.64 centimeters long and 66.04 centimeters wide. One inch equals 2.54 centimeters. Use the ratio table to find the ratio of the length to the sum of the length and width in inches and in simplest form.
Answer:8: 21
Step-by-step explanation:
Given : An architect builds a model of a park in the shape of a rectangle. The length of the model = 40.64 centimeters
The width of the model = 66.04 centimeters
Since, .
Then ,
Now, the length of the model =
The width of the model =
Sum of length and width = 16+26=42 inches
Now, the ratio of the length to the sum of the length and width in inches :_
Hence, the ratio of the length to the sum of the length and width in inches in simplest form = 8:21

Which equation shows the result of substituting and expression for y from the first equation into the second equation for the given system {y=x+5 {y-2x=2
Answer:
x-2x = -3 and x = 3
Step-by-step explanation:
Given the expression
y=x+5.... 1
y-2x=2.... 2
Substituting the first equation into the second we will have;
From 2;
y -2x = 2
x+5-2x = 2
x-2x +5 = 2
x-2x = 2-5
x-2x = -3
-x =-3
x =3
Hence the required equation is x-2x = -3 and x = 3
Answer:
(x + 5) – 2x = 2
