Answer: The answer would be 1.6 :)
Answer:
The average velocity is:
4.8 km/hour
Step-by-step explanation:
1 hour = 60 minutes
20 minutes = 20/60 = 0.3333 hour
Proportions
1.6km ⇔ 0.3333 hour
W km ⇔ 1 hour
W = 1.6*1/0.3333
W = 4.8 km/hour

Complete Question
A local pizza shop has a membership program for frequent buyers the membership cost $25 per month the members get a discount price of $1.50 per pizza slice. Aaliyah purchased a membership to this pizza shop , how much would Aaliyah I have to pay the pizza shop if she bought six slices of pizza this month ?
What would be the monthly cost for a slice of pizza?
Answer:
a) $34
b) $26.50
Step-by-step explanation:
From the question:
Membership for frequent buyers in a month = $25
Discount price = $1.50 per pizza slice
a) How much would Aaliyah I have to pay the pizza shop if she bought six slices of pizza this month ?
This is calculated as:
Membership cost in a month + Discount price × Number of pizzas bought
= $25 +( $1.50 × 6 slices of pizza)
= $25 + $9
= $34
b) What would be the monthly cost for a slice of pizza?
This is calculated as:
Membership cost + Discount price × Number of slices
= $25 + $1.50 × 1
= $26.50

Select the correct answer for each statement. (k+2, k+3 , k+4) or (k+10, k+12, k+14) will yield consecutive odd integers. (k+6, k+8 , k+10) or (k+1, k+2, k+3) will yield consecutive integers.
Answer:
Step-by-step explanation:
one
The only really certain way of getting an odd integer is to do 2k + 1. Therefore the answer should be something like 2k+1, 2k+3, 2k + 5
The best I can do for the first one is to assume that k is odd and that the answer is k + 10, k+12, k+14, but I would ask your instructor if this is merely the best answer out of a poor lot or if the question really has no answer.
Two things should be noted.
1. k has to be odd.
2. The first choice has to give consecutive integers because what is added on is 2 3 and 4. Those numbers are consecutive.
Two
k+1, k+2, k+3. See point 2 above. k is a constant and any number. 1,2,3 are consecutive so the results are consecutive. Even if k < 0 the numbers will be consecutive.
k= - 10
k+1 = - 9
k+2 = -8
k+3 = - 7
These are consecutive.
Your first choice will give either consecutive odd or even numbers depending on what k is.
If k = even, then k+6, k+ 8, k+10 will all be even.
If k = odd then the givens will be odd.
2k+9, 2k+11, 2k+13 will yield consecutive odd integers.
k+6, k+8, k+10 will yield consecutive integers.

Step-by-step explanation:
Enter the answer in the space provided.
Mariah walks 6 miles per hour. Bobby walks 4, 400 yards in a half-hour.
Given that 1 mile = 1,760 yards, how much faster does Mariah walk than Bobby, in miles per hour?
Enter the answer in the space provided.
Shaun rides his bike at a speed of 19 miles per hour. How far, in miles, does Shaun travel in 25 minutes when rounded to the nearest
hundredth?
Answer:
Part 1: 1 mile.
Part 2: 1.32 mph.
Step-by-step explanation:
The correct speed of Mariah walks faster than Bobby, in miles per hour - 1 mile per hour.
Shaun travel in 25 minutes in the given case, when rounded to the nearest hundredth - 7.92 miles.
Part 1.
Given:
speed of Mariah = 6 miles per hour
speed of Bobby = 4, 400 yards per half hour
= 8800 yards per hour
1 mile = 1760 yards
Solution:
To find out the speed difference of both Mariah and Bobby, we need to convert speeds in the same units that is mile:
=> speed of bobby = [tex]\frac{8800}{1760}[/tex]
=> speed of bobby = 5 miles per hour
as it is given 1 mile = 1760 yards
=> Now, the speed difference between Mariah and Bobby is
= 6 - 5
= 1 mile per hour.
Thus, Mariah walks faster than Bobby, in miles per hour - 1 mile per hour.
Part 2:
Given:
Speed of Shaun = 19 miles per hour
distance traveled in 25 minutes = ?
Solution:
To find out the traveled distance by Shaun in 25 minutes we need to find the speed per minute:
1 hour = 60 minutes
So as given, 19 miles per 60 minutes
then speed per minute = [tex]\frac{19}{60}[/tex]
= 0.316
then traveled in 25 minutes-
=> [tex]0.316*25[/tex]
=> = 7.92
Thus, Shaun travel in 25 minutes in the given case, when rounded to the nearest hundredth - 7.92 miles.

the first term of an arithmetic sequence is equal to 200 and the common differencence is equal to -10. find the value of the 20th term
Answer:
The value for 20th term is 10.
Step-by-step explanation:
First, you have to find the formula for the sequence.
[tex]an = a + d(n - 1)[/tex]
[tex]let \: a = 200,d = - 10[/tex]
[tex]an = 200 - 10(n - 1)[/tex]
[tex]an = 200 - 10n + 10[/tex]
[tex]an = - 10n + 210[/tex]
Given that the formula of this sequence is an = -10n + 210. Next, you have to find 20th term :
[tex]let \:n = 20[/tex]
[tex]20th \: term = - 10(20) + 210[/tex]
[tex]20th \: term = - 200 + 210[/tex]

Write the equation of the line in slope-intercept form.
There are two numbers which add up to 20. If one number is five more than four times the other, find the numbers.
Answer:
3 and 17
Step-by-step explanation:
Let x and y represent the numbers.
x + y = 20 . . . . . . . . the numbers add up to 20
x = 5 + 4y . . . . . . . . one number is 5 more than 4 times the other
Substituting the second equation into the first:
(5 +4y) +y = 20
5y = 15 . . . . . . . . . . subtract 5
y = 3 . . . . . . . . . . . . divide by 5
x = 20 -3 = 17
The numbers are 17 and 3.

Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
29.5 49.3 30.6 28.2 28.0 26.3 33.9 29.4 23.5 31.6
Sort in ascending order of magnitude :
23.5,26.3,28.0,28.2,29.4,29.5,30.6,31.6,33.9,49.3
A) Range of the sample data:
(maximum - minimum)
49.3 - 23.5 = 25.8
B) sample variance :
S² = ∑ (x − m)²/ n − 1.
m = mean ; n = number of observations
m = (23.5 + 26.3 + 28.0 + 28.2 + 29.4 + 29.5 + 30.6 + 31.6 + 33.9 + 49.3) = 310.3 / 10 = 31.03
∑ (x − m)² = 443.801
n - 1 = 10 - 1 = 9
S² = ∑ (x − m)²/ n − 1
S² = 443.801 / 9
S² = 49.311222 = 49.31
C) The standard deviation (s):
S = √[∑ (x − m)²/ n − 1]

Tenemos dos problemas de proporciones.
Las soluciones son:
A) p = 6/36 = 1/6B) p = 5/8.A) Lamentablemente el primero está incompleto, lo reescribamos como:
"en una caja de 36 naranjas, si 6 se han descompuesto, ¿qué parte del contenido de la caja se desperdicia?"
Solo para mostrar la matemática que se necesita para este tipo de problemas.
La parte que del contenido de la caja que se desperdicia será igual al cociente entre el número de naranjas que se desperdician y el número total de naranjas, o sea:
p = 6/36 = 1/6
Se desperdicia 1/6 del contenido de la caja.
B) Sabemos que la pizza originalmente tiene 8 porciones.
Luego tu papá, hermano, y tía comen una porción (3 en total)
Entonces quedan: 8 - 3 = 5 porciones.
La parte que queda será el cociente entre lo que queda y la cantidad inicial, o sea:
p = 5/8.
Quedan 5/8 de la pizza.

Please assist me with these problems and show the work. Part 1 4. From a horizontal distance of 80.0 m, the angle of elevation to the top of a fragpole is 18°. Calculate the height of the flagpole to the nearest tenth of a metre. 5. A 9.0 m ladder rests against the side of a wall. The bottom of the ladder is 1.5 m from the base of the wall. Determine the measure of the angle between the ladder and the ground, to the nearest degree.
Answer:
4) About 26.0 feet
5) About 80 degrees.
Step-by-step explanation:
Please refer to the (badly drawn, sorry) drawings.
4)
So for a horizontal distance of 80 meters, the angle of elevation is 18 degrees. And we want to find the height.
The horizontal distance is adjacent to the angle, and the height is opposite to the angle. Thus, we can use the trigonometric ratio tangent.
Recall that tangent is:
[tex]\tan(x)=opp/adj[/tex]
Substitute 18 for x, h for opposite, and 80 for adjacent. Thus:
[tex]\tan(18)=\frac{h}{80}[/tex]
To solve for h, multiply both sides by 80:
[tex]h=80\tan(18)[/tex]
Use a calculator:
[tex]h\approx25.9938[/tex]
So, the height is approximately 26.0 feet.
5)
So, this time, we need to find the angle. We know the hypotenuse and the side adjacent to the angle. So, we can use cosine. Recall that:
[tex]\cos(x)=adj/hyp[/tex]
Substitute 1.5 for adjacent and 9 for the hypotenuse. Thus:
[tex]\cos(x)=\frac{1.5}{9}[/tex]
Take the inverse cosine of both sides:
[tex]x=\cos^{-1}(\frac{1.5}{9})[/tex]
Use a calculator:
[tex]x\approx80.4059\textdegree\approx80\textdegree[/tex]
So, the angle is about 80 degrees.
And we're done!
Answer:
4) About 26.0 feet
5) About 80 degrees.
