Using the relation between velocity, distance and time, the equation that relates x and y is given by:
x + y - 3 = 0.
What is relation between velocity, distance and time?Velocity is distance divided by time, hence:
[tex]v = \frac{d}{t}[/tex]
In this problem, he wants to run 30 km at a rate of 10 km per hour, hence:
[tex]10 = \frac{30}{t}[/tex]
10t = 30
t = 3.
The total time is 3 hours. Considering x as the number of hours he runs and y the number of hours he walks, along with the total time, the equation is given by:
x + y = 3.
In standard form:
x + y - 3 = 0.

6 inches = _____ centimeters
Answer:
15.2 cm
Step-by-step explanation:
Inch to centimeter conversion is multiplying the number of inches by 2.54
6 * 2.54 = 15.24
the 2 is in the tenths place
4 is less than and not equal to 5, therefore the 2 stays the same
6 inches = 15.2 centimeters

Arectangular fish tank measures 35 cm long, 24 cm wide, and 50 cm high. It contains 25 liters of water. How many more liters of water are needed to fill the fish tank completely?
Answer:
i think it is a but i am not sure
Step-by-step explanation:
please get this right !!!
Answer:
3rd option
Step-by-step explanation:
probability (P) is calculated as
P = [tex]\frac{desired outcome}{total outcomes}[/tex]
deired outcome is red marble = 4
total outcomes = 4 + 2 + 3 = 9
then
P(red) = [tex]\frac{4}{9}[/tex]
since the marble is not replaced then total outcomes = 8
desired outcome is yellow marble = 2
P(blue) = [tex]\frac{2}{8}[/tex] = [tex]\frac{1}{4}[/tex]
then
P(red and yellow ) = [tex]\frac{4}{9}[/tex] × [tex]\frac{1}{4}[/tex] = [tex]\frac{1}{9}[/tex]

can anyone help me answer this
Can anyone help me been stuck for a while
Answer:
total marbles = 15 + 12 = 27
blue marbles = 12
probability of blue marble = 12/27 simplifies to 4/9
Question:
Can anyone help me been stuck for a while.
Answer:
[tex]\frac{4}{9}[/tex]
Step-by-step explanation:
The bag has 15 white marbles,
and 12 blue marbles.
Add the totals together, and you would get:
27.
turn that into a fraction:
[tex]\frac{12}{27}[/tex]
then simplify:
Find the GCD (or HCF) of numerator and denominator
GCD of 12 and 27 is 3
Divide both the numerator and denominator by the GCD
12 ÷ 3
27 ÷ 3
Reduced fraction:
[tex]\frac{4}{9}[/tex]
Therefore, [tex]\frac{12}{27}[/tex] simplified to lowest terms is:
[tex]\frac{4}{9}[/tex]
Therefore, your answer would be: [tex]\frac{4}{9}[/tex]

There is a pair of parallel sides in the following shape. 4 4 6 What is the area of the shape?
============================================================
Explanation:
It might help to rotate the figure so the parallel sides are horizontal. This is optional.
The parallel bases are [tex]b_1 = 6[/tex] and [tex]b_2 = 4[/tex] in either order.
The height is h = 4 which is always perpendicular to both bases.
Plug these values into the trapezoid area formula.
[tex]A = \frac{h(b_1 + b_2)}{2}\\\\A = \frac{4(6+4)}{2}\\\\A = \frac{4(10)}{2}\\\\A = \frac{40}{2}\\\\A = 20\\\\[/tex]
The area of the trapezoid is 20 square units.
-----------
Another pathway is to break the trapezoid into a rectangle up top and a triangle down below.
The rectangle is 4 by 4 with area 4*4 = 16
The triangle has a base of 6-4 = 2 and height of 4, so its area is base*height/2 = 2*4/2 = 8/2 = 4
Overall the total area is rectangle+triangle = 16+4 = 20 square units.

SOMEONE PLS HELP !!!!!!!
Answer:
5/2
Step-by-step explanation:
4(x + 7) = 38
x + 7 = 38/4
x = 38/4 - 7
x = 38/4 - 28/4
x = 10/4
x = 5/2
Reasoning:
1. Divide both sides by 4
2. Isolate variable by subtracting 7 on both sides
3. Convert 7 into an improper fraction to subtract constants
4. Simplify

The price of a gallon of gasoline decreased by $0.04. Which number line shows a point
that represents the change in the price of a gallon of gasoline, in dollars?
I believe it's D
A decrease means you're going in the negative direction. And 0.04 is way less than 0.50
So D is the most logical answer
Mia buys 404.6 square feet of new wood
flooring. How much did she pay for the wood if it cost $0.99 Per square foot?
Answer:
$400.55 (to the nearest cent)
Step-by-step explanation:
she paid
= 404.6 x 0.99
= 400.554
= $400.55 (to the nearest cent)
hope this helps!
Answer:
$ 400.554
Step-by-step explanation:
Let the unknown price be x.
1 ft² ⇒ $ 0.99
404.6 ft² ⇒ x
Let us use cross multiplication to find the value of x.
0.99 × 404.6 = 1 × x
400.554 = x
Therfore, she'll pay $ 400.554 for 404.6 ft²
Determine formula of the nth term 2, 6, 12 20 30,42
Check the forward differences of the sequence.
If [tex]\{a_n\} = \{2,6,12,20,30,42,\ldots\}[/tex], then let [tex]\{b_n\}[/tex] be the sequence of first-order differences of [tex]\{a_n\}[/tex]. That is, for n ≥ 1,
[tex]b_n = a_{n+1} - a_n[/tex]
so that [tex]\{b_n\} = \{4, 6, 8, 10, 12, \ldots\}[/tex].
Let [tex]\{c_n\}[/tex] be the sequence of differences of [tex]\{b_n\}[/tex],
[tex]c_n = b_{n+1} - b_n[/tex]
and we see that this is a constant sequence, [tex]\{c_n\} = \{2, 2, 2, 2, \ldots\}[/tex]. In other words, [tex]\{b_n\}[/tex] is an arithmetic sequence with common difference between terms of 2. That is,
[tex]2 = b_{n+1} - b_n \implies b_{n+1} = b_n + 2[/tex]
and we can solve for [tex]b_n[/tex] in terms of [tex]b_1=4[/tex]:
[tex]b_{n+1} = b_n + 2[/tex]
[tex]b_{n+1} = (b_{n-1}+2) + 2 = b_{n-1} + 2\times2[/tex]
[tex]b_{n+1} = (b_{n-2}+2) + 2\times2 = b_{n-2} + 3\times2[/tex]
and so on down to
[tex]b_{n+1} = b_1 + 2n \implies b_{n+1} = 2n + 4 \implies b_n = 2(n-1)+4 = 2(n + 1)[/tex]
We solve for [tex]a_n[/tex] in the same way.
[tex]2(n+1) = a_{n+1} - a_n \implies a_{n+1} = a_n + 2(n + 1)[/tex]
Then
[tex]a_{n+1} = (a_{n-1} + 2n) + 2(n+1) \\ ~~~~~~~= a_{n-1} + 2 ((n+1) + n)[/tex]
[tex]a_{n+1} = (a_{n-2} + 2(n-1)) + 2((n+1)+n) \\ ~~~~~~~ = a_{n-2} + 2 ((n+1) + n + (n-1))[/tex]
[tex]a_{n+1} = (a_{n-3} + 2(n-2)) + 2((n+1)+n+(n-1)) \\ ~~~~~~~= a_{n-3} + 2 ((n+1) + n + (n-1) + (n-2))[/tex]
and so on down to
[tex]a_{n+1} = a_1 + 2 \displaystyle \sum_{k=2}^{n+1} k = 2 + 2 \times \frac{n(n+3)}2[/tex]
[tex]\implies a_{n+1} = n^2 + 3n + 2 \implies \boxed{a_n = n^2 + n}[/tex]

Answer:
Both
Claire
Andre
Neither
Step-by-step explanation:
We have to determine whether each point lies on Claire's line (blue) and whether it lies on Andre's line (black).
Point A is the intersection of both lines, hence the statement represents them both.
Point B only lies on Claire's line.
Point C is the start of Andre's line.
Point D is outside of both lines.
