Answer:
37.5 miles per hour
Step-by-step explanation:
To find the miles per hour, you divide the miles by hours. If you divide 225/6, you get 37.5. You can double check this by dividing another set, like 450/12 and see that you still get 37.5. Hope this helps! :)

jamie's string is 10ft 1in long. emma's string is 6ft 4in long. how much longer is jamie's string
Answer:
Jamie's string is 3ft and 9in
Step-by-step explanation:
10ft 1in
-6ft 4in
=3ft 9in
Answer:
3ft 9 in
Step-by-step explanation:
So, in each foot there's 12 inches. Knowing that, the operation you use is subtraction. So you do 10 ft 1 in - 6 ft 4 in. If you do that operation knowing that 12 inches=1 foot, then you should get 3 ft 9 in.
Please let me know if there is still any confusion.
Given the explicit expression f (n) = 5n - 2, write a set showing the sequence, and write a recursive expression.
Answer:
[tex]f(n) = 5 + f(n - 1)[/tex]
Step-by-step explanation:
Given
[tex]f(n) = 5n - 2[/tex]
Required
Write a recursive expression
[tex]f(n) = 5n - 2[/tex]
When n = 1
[tex]f(1) = 5 * 1 - 2 = 5 - 2 = 3[/tex]
[tex]f(1) = 3[/tex]
When n = 2
[tex]f(2) = 5 * 2 - 2 = 10 - 2 = 8[/tex]
[tex]f(2) = 8[/tex] can be rewritten as
[tex]f(2) = 5 + 3[/tex]
Substitute 3 for f(1)
[tex]f(2) = 5 + f(1)[/tex]
Express 1 as 2 - 1
[tex]f(2) = 5 + f(2-1)[/tex] ----- (1)
When n = 3
[tex]f(3) = 5 * 3 - 2 = 15 - 2 = 13[/tex]
[tex]f(3) = 13[/tex] can be rewritten as
[tex]f(3) = 5 + 8[/tex]
Substitute 8 for f(2)
[tex]f(3) = 5 + f(2)[/tex]
Express 2 as 3 - 1
[tex]f(3) = 5 + f(3 - 1)[/tex] ------ (2)
Write out (1) and (2)
[tex]f(2) = 5 + f(2-1)[/tex]
[tex]f(3) = 5 + f(3 - 1)[/tex]
Replace 2 and 3 with n in both cases; This gives
[tex]f(n) = 5 + f(n - 1)[/tex]
Hence;
The recursive is [tex]f(n) = 5 + f(n - 1)[/tex]
Diane owes $11901.00 to the bank after completing her college degree. With the funds from her new job she is paying back $153.00 per month. Her friend Teresa was given $4906.00 in the bank for college from her family, and she is spending $337.00 per month out of this college fund. If these were continuous functions, after how many months will Diane have the same bank balance than Teresa, rounded to the nearest tenth
4d + 7e = 68 -4 - 6e = -72
Answer:
Step-by-step explanation:
4d + 7e = 68
-4d - 6e = -72
e = -4
4d + 7(-4) = 68
4d - 28 = 68
4d = 96

Please help ik its kinda esay but is dificlut for me
Answer:
see explanation
Step-by-step explanation:
For a relation to be a function each value of x on the domain can only map to one unique value of y in the range.
For the given point, we can see that
x = 1 → y = 4 and x = 1 → y = 1
This breaks the function rule, thus the set is not a function
Explanation:
The list of first numbers of the ordered pairs is ...
1, 3, 1, 9, 0.
There is a repeated value, 1, so the relation cannot be a function. Each domain value can only appear once in a relation that is a function.

2) The wire length 176 cm is first bent into a square
and then into a circle
which one will have more area? (II= 22/7)
Length of Wire = 176 cm
It's bent into a square.
Side of square = 176/4 = 44 cm
Area of square = Side × Side = 44 × 44 = 1,936 sq.cm
Then it's bent into a circle.
Circumference of the circle = 2πr = 176 cm
Circumference = r = 176/2 × 7/22 = 28 cm
Area of circle = πr^2
Area = 22/7 × 28 × 28
Area = 2,464 sq.cm
The Circle will have more area than the square.
9.6= 1.2b find b please show work
PLEASEEEE
Answer:
8
Step-by-step explanation:
1.) 9.6=1.2b
2.) 9.6/1.2=1.2b/1.2
3.)b=8
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{b = 8}}}}}[/tex]
Step-by-step explanation:
[tex] \star{ \sf{ \: \: \: 9.6 = 1.2b}}[/tex]
Swap the sides of the equation
[tex] \hookrightarrow{ \sf{1.2b = 9.6}}[/tex]
Divide both sides by 1.2
[tex] \hookrightarrow{ \sf{ \frac{1.2b}{1.2} = \frac{9.6}{1.2} }}[/tex]
Calculate
[tex] \hookrightarrow{ \bold{ \boxed{ \sf{b = 8}}}}[/tex]
The value of b is 8

The length of a square garden is twice a number. If the perimeter of the garden is 36, find the number.
Answer:
x = 4.5
Step-by-step explanation:
l = 2x
p = 4l
note: 4l in this case because it is a square
plug in l into equation p
36 = 4(2x)
36 = 8x
divide by 8
x = 4.5
Geri spent Friday, Saturday, and Sunday selling a total of 24 magazine orders for her school fundraiser. The amounts she sold, respectively, on the three days were consecutive even integers. How many did she sell on each day?
Answer:
8
Step-by-step explanation:
So since there is 3 days and the total is 24 you divide and that will give you 8! Integers are a whole number btw (:
When they ask, for example "What is the value of √100?" are they asking what is the square root of 100?

Answer:
Yes. The term [tex]\sqrt{}[/tex] means "square root".
If there is a number beside the symbol, for example [tex]\sqrt[3]{}[/tex], this means to cube root. But if there is no number, it just simply means square root.

A fruit juice company includes 1.247 ounces of orange juice in a 6.85 ounce bottle of mixed fruit juice. How much of the bottle of mixed fruit juice is not orange juice
Answer:
5.603 ounces
Step-by-step explanation:
From the information given, you know the ounces of orange juice included in a bottle and the ounces of mixed fruit juice that the bottle has. So, to be able to determine how much of the bottle of mixed fruit juice is not orange juice, you have to subtract the ounces of orange juice in the bottle from the ounces of mixed fruit juice that it has:
6.85-1.247=5.603
According to this, the answer is that the bottle of mixed fruit juice has 5.603 ounces that are not of orange juice.
The midpoint of AB is M (5,1). If the coordinates of A are (3,6), what are the
coordinates of B answers
The midpoint of a line segment means a point that lies in the mid of the given line segment. The coordinates of point B are (7, -4).
What are the coordinates of the midpoint of the line segment AB?Midpoint, as the word suggests, means the point which lies in the middle of something. The midpoint of a line segment means a point that lies in the mid of the given line segment. Suppose we've two endpoints of a line segment:
A(p,q), and B(m,n)
Then let the midpoint be M(x,y) on that line segment. Then, its coordinates are:
[tex]x = \dfrac{p+m}{2}[/tex]
and
[tex]y = \dfrac{q+n}{2}[/tex]
Given that the midpoint of AB is M whose coordinates can be written as,
The x-coordinate of point B,
[tex]x_m = \dfrac{(x_A + x_B)}{2}[/tex]
[tex]5 = \dfrac{(3 + x_B)}{2}[/tex]
10 = 3 + x
x = 10 - 3
x = 7
The y-coordinate of point B,
[tex]y_m = \dfrac{(y_A + y_B)}{2}[/tex]
[tex]1 = \dfrac{(6 + y_B)}{2}[/tex]
2 = 6 + y
y = 2 - 6
y = -4
Hence, the coordinates of point B are (7, -4).

Answer:
-2r+8
Step-by-step explanation:
4r-7r+8+r
5r-7r+8
-2r+8
-2r+8
The first step is to combine like terms. These would be 4r, -7r, and r since they have the same variable. This gives you -2r. Since there are no other like terms to combine, you end up with -2r+8
