Gerry and Tony live 11 miles apart. Gerry leaves his home at 2:00 PM and bikes toward Tony's house at 25 miles/hour. At the same time, Tony leaves his home and bikes toward Gerry's house at 30 miles/hour. They wave as they pass each other. As soon as each boy reaches the others' home, they turn back around towards their own homes. This time, they stop when they see each other. How far are they from Gerry's home when they stop?

:) please give a heart for thanks
and brainliest crown :)
Step-by-step explanation:
For both d=r*t
Each bikes to others house and leave at the same time so for Tony,
11 = 30*t
t= 11/30 hours
for Gerry,
11 = 25*t
t= 11/25 hours
Comparing these, with LCD,
Tony's time is 55/150
Gerry's time is 66/150
So Tony got to Gerry's house 11/150 hours quicker than Gerry got to Tony's house.
Now they turn around and head back toward each other. If they leave at the same exact time, the elapsed time for each until they met would be the same so t (for tony) = t (for gerry), but Tony got a head start.
We start the stopwatch when Gerry turns around 11/150 hours after Tony has turned around. If Gerry's time to where they meet from Tony's house t(gerry), then Tony's time from Gerry's house is t(gerry) + 11/150
Step-by-step explanation:
For both d=r*t
Each bikes to others house and leave at the same time so for Tony,
11 = 30*t
t= 11/30 hours

A number c increased by 3 is greater than -27.
Answer:
Inequality: c + 3 > -27
Write the number 270 as a sum of three numbers so that the sum of the products taken two at a time is a maximum. (Enter the three numbers as a comma-separated list.)
Answer:
x=y=z=90.
Step-by-step explanation:
let the 3 numbers be x,y,z.
let s be sum
s=x+y+z
we need to maximize xy+yz+zx
or , xy + y(270-(x+y))+x(270-(x+y)) = P(x)
Use Lagrange's Multipliers
⇒ΔP= λΔS
⇒[tex]\frac{x+y}{x+z} =1[/tex]
⇒y=x
⇒\frac{x+z}{x+y} =1
⇒z=y
⇒x=y=z
⇒3x = 270
⇒x= 90
hence, x=y=z=90.
x-axis =____
y-axis =____
y= x ____
y= -x____
Answer:
x-axis = (2, -3)
y-axis = (-2, 3)
y = x (3, 2)
y= -x (-3, -2)
Step-by-step explanation:
x-axis = (2, -3) The point is below the x-axis.
y-axis = (-2, 3) The point is left of the y-axis
y = x (3, 2) Plot the line y = x. The point is on the other side of the line.
y= -x (-3, -2) Plot the line y = -x. The point is on the other side of the line.

i did it on edg2020
Answer:
(2.5,150)(4,240)
slope = (240 - 150) / (4 - 2.5) = 90 / 1.5 = 60
y = mx + b
slope(m) = 60
(4,240)...x = 4 and y = 240
now we sub and find b, the y int
240 = 60(4) + b
240 = 240 + b
240 - 240 = b
0 = b
so ur equation is : y = 60x + 0 which is written as : y = 60x <==

There are 5 quarts left in the fridge. How many liters are in the fridge? (1 quart = 0.946 liters).
An experiment consists of rolling a single die and selecting a card from a standard deck. Use this information to answer the following three questions. What is the probability of rolling a 5 and selecting the ace of hearts
Answer:
1/160
Step-by-step explanation:
Assuming that you want to roll a 5 and then select the ace of hearts that would make this a sequence of events. In order to find the probability of this happening, you would need to multiply the probability of each of these events happening separately with one another.
Since there are a total of 6 possible outcomes when rolling a die (1,2,3,4,5,6) which rolling a 5 is only one of the options. Meaning that the probability of rolling a 5 is 1/5.
In a deck of cards, there are a total of 32 cards in the deck and only 1 of those cards is an ace of hearts. Meaning that the probability of getting the ace of hearts is 1/32. Now we simply multiply these two probabilities together to get the probability of the sequence.
1/5 * 1/32 = 1/160
Help me with this question Pleaseee
Answer:
The answer is 81°
Step-by-step explaination:
To start, the top right angle and the bottom left angle are alternate interior angles, making them congruent. The same justification goes for the angles in the top left and bottom right. With this in mind, 37° + 44° = 81°. Every triangle's angles always add up to 180°, meaning that 180° - 81° = 99°. Because angle n and the angle we just found to be 99° are supplementary, they also add up to 180°, therefore 180° - 99° = 81° which is the value of angle n.

Step-by-step explanation:
To subtract fractions, find the LCD and then combine.
506
Please give me brainiest and also add me please.
Answer:
506
Step-by-step explanation:
First, we have to solve 8 to the power of 3 according to PEMDAS, which will give us 512.
Since we have to follow PEMDAS or GEMDAS (whichever you know), we will have to multiply 9 by 2 next. That will give us the equation: 512 - 18 / 3
Then we have to divide 18 by 3 to give us 6 which will give us the equation: 512 - 6 which we can solve to get 506

Which graph represents the equation (x – 1)2 + (y + 1)2 = 9?
Answer:
D
Step-by-step explanation:
The given equation (x – 1)² + (y + 1)² = 9 represents a circle with the center (1, -1) and a radius of 3.
What are the properties of the circle?The circumference, which is the distance around the object, the diameter, which is the length of a circle measured from one end to the other and passing through its center, and the radius, which is equal to half of the diameter, are the three key characteristics.
Given an equation (x – 1)² + (y + 1)² = 9
The general coordinate equation of a circle is:
(x-h)² + (y - k)² = r²
Where,
(h, k) is the center of a circle,
"r" is the radius of the circle.
Comparing with the general equation of a circle:
h = 1,
k = -1
r² = 9
r = 3
thus, the given equation (x – 1)² + (y + 1)² = 9 represents a circle with the centre (1, -1) and the radius of 3.

The length of the base of an isosceles triangle is x. The length of a leg is 3x - 4. The perimeter of the triangle is 76. Find x.
X=
Answer:
12
Step-by-step explanation:
Hi!
We're given that the perimeter is 76. A triangle's perimeter is given by the sum of all of the sides. So, we'll find the lengths of the sides of the triangle and add them.
This is an isosceles triangle. The legs of an isosceles triangle are equal. In this problem, we're given the length of one leg: 3x-4. That means that the length of the other leg is also 3x-4. Now, the last side of the triangle is x ("base is x).
2(3x-4) + x = 76
6x-8+x=76
7x-8=76
7x=84
x=12
Let's check our answer.
3(12) - 4 =36-4 = 32
32 times 2 = 64 +12 =76
Correct!
