Ana wished to compute for the average speed of a moving bus on a straight line highway, She noted the distance covered. What other quantity should she record?
A. Acceleration
B. Direction
C. Time
D. Velocity
The other quantity needed to calculate the average speed is time.
What is average speed?
Average speed is the total distance travelled per time. It is how fast an object moves with respect to time.
Average speed = total distance / total time
For example, if the distance travelled is 100km and the total time is 10 hours, average speed is 10 km/hr (100 / 10).

Answer:
x = [tex]\frac{1-by}{y-a}[/tex]
Step-by-step explanation:
y = [tex]\frac{ax+1}{x+b}[/tex] ← multiply both sides by (x + b)
y(x + b) = ax + 1 ← distribute parenthesis on left side by y
yx + by = ax + 1 ( subtract ax from both sides )
yx - ax + by = 1 ( subtract by from both sides )
yx - ax = 1 - by ( factor x out of each term on the left side )
x(y - a) = 1 - by ← divide both sides by (y - a)
x = [tex]\frac{1-by}{y-a}[/tex]
Answer:
Step-by-step explanation:
1. Eliminate fractions by multiplying both sides of this equation by x + b:
y(x + b) = ax + 1
2. Perform the indicated multiplication: xy + yb = ax + 1
3. Group together the x-terms xy - ax = 1 - yb, or x(y - a) = 1 - yb
1 - yb
4. Divide both sides by (y - a): x = ----------------
y - a

Answer:
42
Step-by-step explanation:
fir a 100% is missing 40
divide 28 by 4 and then multiply by 6
Answer:
42 students
40%
72 (end of number line)
Explanation:
How to find the percentage for the 28 students:
100% - 60% = 40%
Knowing that, we now know 28 = 40%. We need to figure out what 10% is equal so we can figure out what 60% is equal.
How to find 10%:
28 ÷ 4 = 7
10% = 7 students
How to find 60% of students:
10 · 6 = 60
7 · 6 = 42
With that information, we can find out the final sum.
40% + 60% = 100%
28 + 42 = 72.
Can someone help me with this??

Tlaloc pumped up 56 balls. He pumped up 5 dodge balls for every 9 other balls. Complete the table.
Total balls will be 14, dodge balls will be 20 and the number of other balls will be 36.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In another word, the equation is a set of variables that have been constructed.
In other words, an equation is a set of variables that are constrained through a situation or case.
The total ball will be the sum of dodge ball + other ball so it will be
5 + 9 = 14
The number of pumped up for a single ball
56/14 = 4
So the number of Tlaloc pumps of dodge ball will be 5 × 4 = 20.
Number of Tlaloc pump of other ball = 9 × 4 = 36.

Answer:
$427,500 dollars
Step-by-step explanation:
Given the following question:
Initial price = 450,000
5% discount
In order to find the answer, we simply find 5% of 450,000.
[tex]\frac{5\times450000}{100} =5\times450000=2250000\div100=22500[/tex]
[tex]450000-22500=427500[/tex]
[tex]r=427500[/tex]
The radio (after a 5% discount) costs "$427,500 dollars."

A sprinter in a 100 dash accelerates uniformly from rest reaching a top speed of 14.7 m/s after 6.00 seconds. He then runs at constant speed for the remainder of the race.
B. How far did he travel in the first phase of the race?
I assume "first phase" refers to the first 6.00 seconds of the dash.
Since the sprinter starts from rest and accelerates uniformly, he covers a distance x after time t of
x = 1/2 at²
where a is his acceleration.
The sprinter's velocity v after time t is
v = at
so that if he attains a speed of 14.7 m/s after 6.00 s, he does so with acceleration a such that
14.7 m/s = a (6.00 s) ⇒ a = 2.45 m/s²
Then in the first 6.00 seconds, the sprinter travels
x = 1/2 (2.45 m/s²) (6.00 s)² = 44.1 m
which expression represents the expression 20x-10 after it has been factored completely? SHOW ME WHAT YOU DID
A. 2(10x-5)
B. 2(2x-1)
C.10(20x-10)
D. 10(2x-1)
Answer:
it is A and D
Step-by-step explanation:
A. 2 * 10x is equal to 20x
and then 2 * 5 is equal to 10
so the answer is 20x-10
D. 10 *2x is equal to 20x
and then 10 * -1 is equal to -10
so the answer is 20x-10

Step-by-step explanation:
solving similarities using equations:
→[tex]\frac{CD}{QD} = \frac{RD}{BD}[/tex]
→ [tex]\frac{x}{39} = \frac{18+x}{26+39}[/tex]
→ [tex]\frac{x}{39} = \frac{18+x}{65}[/tex]
→ 65(x) = 39(18+x)
→ 65x = 702 + 39x
→ 65x - 39x = 702
→ 26x = 702

What is the distance between the points (-2.5,6.5) and (2.5,6.5)
Answer:
5 units
Step-by-step explanation:
The two points have the same y-coordinate so are on a horizontal line. The distance between them is the difference of their x-coordinates:
2.5 -(-2.5) = 2.5 +2.5 = 5.0
The distance between the points is 5 units.

The graph of function f (x) = 2ˣ - 3 is shown in figure.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The function is,
⇒ f (x) = 2ˣ - 3
Now, We get;
At x = 1;
⇒ f (x) = 2ˣ - 3
⇒ f (1) = 2 - 3 = - 1
At x = 2;
⇒ f (x) = 2ˣ - 3
⇒ f (2) = 2² - 3 = 1
Hence, The graph is passing through (1, - 1) and (2, 1).
Thus, The graph of function f (x) = 2ˣ - 3 is shown in figure.

another real estate agent sold a house for $315,000 last week if her commission is 1.25% of the selling price of the home find the amount of her commission. Please explain
Answer:
$ 3937.5
Step-by-step explanation:
First, we convert 1.25% into a decimal.
That would be .0125.
Now we multiply the decimal with the whole number to find our answer.
315000 × .0125 = 3937.5
Therefore, 3937.5 would be the amount of her commission.
