Pablo is on a road trip which will cover a distance of 840 miles. He plans to break the trip up and will complete it over three days. The distances and average speeds for the first two days are shown below.Day One: 55 hours at an average speed of 66 miles per hour. Day Two: 55 hours at an average speed of 58 miles per hour. If the average speed on the third day is 55 miles per hour, how many more hours will it take for Pablo to complete his trip?
Answer: 2.87 hours
Step-by-step explanation:
There may be a typo in the question because 55 hours in a day is not logical so you must have meant 5.5 hours.
In that case, the hours he will require on the third day would require the distance left to calculate. Get this distance from the first 2 days.
Day 1 distance travelled = Time * Speed
= 5.5 * 66
= 363 miles
Day 2 distance travelled = Time * Speed
= 5.5 * 58
= 319 miles
Total distance remaining
:= 840 - 363 - 319
= 158 miles
Travelling at 55 miles per hour, the time to be taken is:
= Distance remaining / Speed
= 158 / 55
= 2.87 miles per hour
Alexa is going to a carnival that has games and rides.Each game cost $3 and each ride cost $4. Alexa spent $54 altogether on 15 games and rides. Determine the number of games Alexa played and the number of rides Alexa went on.
Answer:
Alexa played 6 games and went on 9 rides
Step-by-step explanation:
To get the number of games and rides, you will need to know two number that is divisible by 3 and 4 and the total will be 54, and the addition of there product equals 15
Consider 18 and 36 are the two numbers
18/3 = 6 games and 36/4 = 9 rides.
Answer:

y =3/4 x+2
Answer:
-3/4 slope
Step-by-step explanation:
y = 3/4 x +2 has a slope of 3/4
Perpendicular lines intersect.
So the slope of the perpendicular line must be opposite.
plz what’s the answer ???????????????
Answer:
x = 4
Step-by-step explanation:
Since both sides of the hanger must be equal, one can form an equation based on the given information;
14 = x + 3 + x + 3
Simplify,
14 = 2x + 6
Inverse operations,
14 = 2x + 6

The cost of petrol rises by 2 cents a liter. last week a man bought 20 liters at the old price. This week he bought 10 liters at the new price. Altogether, the petrol costs $9.20. What was the old price for 1 liter? 34 POINTS I MARK BRAINLIEST!
Answer:
We suppose that a is the old price in cents
the total cost of 9.20 $ equals 920 cents
so we have 20 liters bought with the old price (a) and 10 liters with the new price (a + 2). This is translated into this equation where a is the old price therefore our quest to be answered
20 xa + 10 x (a + 2) = 920 (cents)
20 xa + 10 xa + 20 = 920
30 xa + 20 = 920
30 xa = 920 - 20
30 xa = 900
a = 900: 30
a = 30 (cents)
therefore the old price for 1 liter of petrol is 30 cents

what is the a triangle that has equal sides?
Answer:
An equilateral triangle
Step-by-step explanation:
An equilateral triangle has three equal sides and angles. It will always have angles of 60° in each corner.
Answer:
An equilateral.
Explanation:
Has all three equal sides and angles (let me know if this isn't the one you were looking for)
What's the value of x? Enter your answer in the box.
x = {}
All three angles on a triangle always equal 180°.
Example: 100°+40°+40°=180°
102+39=141°
180-141=39°
x = 39°
Plot the image of quadrilateral ABCD under a reflection across line l.
Please answer!!!!
Answer:
Step-by-step explanation:
The coordinates of the reflection of a point (x, y), across the y-axis is the point (-x, y)
Please find attached the plot of the image of quadrilateral ABCD under a reflection of the line l
Method:
The coordinates of the vertices of the given quadrilateral ABCD are as follows
A(-2 0), B(-3, 4), C(0, 4), and D(-1, 1)
Due to its orientation, the line l can be taken as being equivalent to the y-axis
The coordinates of the image of (x, y) following a reflection across the y-axis is (-x, y)
Therefore, for the image of the quadrilateral ABCD following a reflection across the y-axis to give the quadrilateral A'B'C'D', the coordinates of A'B'C'D' are;
A(-2 0), reflected across the y-axis gives the image A'(2, 0)
B(-3, 4), reflected across the y-axis gives the image B'(3, 4)
C(0, 4), reflected across the y-axis gives the image C'(0, 4)
D(-1, 1), reflected across the y-axis gives the image D'(1, 1)
The coordinates with which the image of the of the quadrilateral ABCD can be plotted are therefore;
A'(2, 0), B'(3, 4), C'(0, 4), and D'(-1, 1)
The plot of the quadrilateral ABCD and the image A'B'C'D' can be created using MS Excel presented in the attached graph

Tres números naturales consecutivos son tales que el cuadrado del número intermedio es 15 más que la suma de los otros dos. Sea mmm el número intermedio. Escribe una ecuación para mmm. Nota: no necesitas ingresar la ecuación en forma cuadrática.
Responder:
m² = 15 + 2m
Explicación paso a paso:
Tres números naturales consecutivos:
Número medio = m
Los otros dos números son; m - 1; m + 1
Por tanto, tenemos:
m - 1, m, m + 1
Cuadrado de m = (m - 1) + (m + 1) + 15
m² = 15 + (m - 1 + m + 1)
m² = 15 + (m + m)
m² = 15 + 2m
