Yochanan walked from home to the bu top at an average peed of
mph. He immediately got on hi chool bu and traveled at an average peed of
mph until he go to chool. The total ditance from hi home to chool i
mile, and the entire trip took
hour. The following ytem of equation repreent thi:
Distance covered by Yochanan by walking = 5 km
Distance covered by Yochanan by bus = 30 km
Given the values in the question,
The average speed of Yochanan when he walked to the bus stop from home = 5 km/h
The average speed of the bus till Yochanan reached his school = was 60 km/h
The total distance between his school from home = is 35 km
Time is taken by the entire trip = 1.5 hours
Relation between Distance, Time, and speed,
⇒ Average Speed = [tex]\frac{Distance}{Time}[/tex]
Let us consider that Yochanan walked = a km
The bus travelled = 35 - a
We know that the total time is constant so,
⇒ T = T1 + T2
⇒ 1.5 = [tex]\frac{x}{5} + \frac{35-a}{60}[/tex]
Solving for a,
⇒ 1.5 = [tex]\frac{12a + 35 - a}{60}[/tex]
⇒ 11 a + 35 = 90
⇒ 11 a + 55
⇒ a = 5
The distance covered by Yochanan by walking = a = 5 km
Distance covered by bus = 35 - a
= 35 - 5
= 30 km
Therefore, the distance covered by Yochanan by walking = is 5 km, distance covered by Yochanan by bus = is 30 km

A tree, which i approximately 80% of it full height, i preently 60 feet tall. How tall will the tree be when it i fully grown?
The tree will be 75 feet tall when it will be fully grown.
The total tree height is the distance between the tree's base and its highest point on the ground. A yardstick provides a quick and relatively accurate way to gauge the height of a tree.
If the tree is currently 60 feet tall and is approximately 80% of its full height, we can assume that the tree will be 100% of its full height when it is fully grown. To determine the full height of the tree, we can use the proportion:
60 feet / 80% = X feet / 100%
We can then cross-multiply to solve for X:
X = (60 feet * 100%) / 80%
= 75 feet
So, when the tree is fully grown, it will be approximately 75 feet tall.

The sum of two number is 92. Their difference i 20Let x and y represent the 2 number. Let x=the lager value and smaller valuex = 92 + 20 = 11,y = 92 - 20 = 72
Let x = the larger value and y = the smaller value.
We know that the sum of x and y is 92, so
x + y = 92
We also know that the difference between x and y is 20, so
x - y = 20
Add the two equations to get
2x = 112
Divide by 2 to get
x = 112
Substitute x = 112 into the first equation to get
112 + y = 92
Subtract 112 from both sides to get
y = 72

The area of a rectangle i 42 quare millimeter. The length i 7 millimeter. What i the perimeter of the rectangle?
millimeter
The area of a rectangle is 42 quare millimeter. The length is 7 millimeter. 28 millimeters is the perimeter of the rectangle.
Perimeter = 2 × (Length + Width)
Perimeter = 2 × (7 + 6)
Perimeter = 28 millimeters
To calculate the perimeter of a rectangle, we need to multiply the length and the width of the rectangle, and then multiply that value by 2. In this case, the length is 7 millimeters, and the area is 42 square millimeters. To calculate the width, we can divide the area by the length, which is 42 divided by 7, which is equal to 6. So the width is 6 millimeters. Now we can calculate the perimeter using the formula: Perimeter = 2 × (Length + Width). Plugging in the values, we get: Perimeter = 2 × (7 + 6) = 28 millimeters.

Conider the following function. (If an anwer doe not exit, enter DNE. ) f(x) = e^−x2
The function has no vertical asymptotes and the horizontal asymptotes of the function is y=0.
In the given question,
Consider the following function.
f(x) = e^{−x^2}
We have to find the vertical asymptote(s), x = Find the horizontal asymptote(s) or y = .
As we know that, a vertical asymptote is a line that runs vertically and guides the graph of the function but does not actually exist on it. Due to its position at an x-value that is outside of function's domain, it is difficult for the curve to ever pass it.
The function f(x) = e^{−x^2} has no undefined points. So the function has no vertical asymptotes.
The limit of the function at x→±∞ is calculated as follows:
[tex]\lim_{x\rightarrow \pm\infty }[/tex]f(x) = [tex]\lim_{x\rightarrow \pm\infty }[/tex]e^{−x^2}

Antonio's dad bought gas for their family's ATV two weeks in a row. Last week, he bought 12 gallons for $35.40. This week, he bought 9 gallons for $25.83. How much more did Antonio's dad pay per gallon last week?
$
per gallon
Answer: $0.08
Step-by-step explanation:
First, let's find last week's price
Take 35.40 divided by 12 = $2.95 per gallon
Next, find this week's price
Take 25.83 divided by 9 = $2.87 per gallon
Then take 2.95 - 2.87 = $0.08
Find the value of z such that 0.12 of the area lies to the right of z. Round your answer to two decimal places.
Answer:
Step-by-step explanation:
To find the value of z such that 0.12 of the area lies to the right of z, we need to know the distribution of the data and the total area under the curve. If the data follows a normal distribution, the area under the curve is always 1, and 0.12 of the area corresponds to a z-value of approximately 0.84.
We can use a standard normal table or a calculator to find the exact value of z. For example, using a standard normal table, we can find that the z-value corresponding to an area of 0.12 to the right of z is 0.8416.
Therefore, the value of z such that 0.12 of the area lies to the right of z is approximately 0.84.

Examine the sequence. From viewing the first 2 terms, we know that it can either be a geometric sequence that multiplies by 11/3 every time the term increases or an arithmetic sequence that adds 8 every time the term increases.
Looking at the 2nd and 3rd term, we know it is an arithmetic sequence because 19 is not equal to 11 times 11/3.

Amy, Becky and Chloe went shopping.
Becky spent only 15% of what Chloe spent.
However, Amy spent 60% more than Chloe.
Together they spent £55.
How much did Amy spend?
Let's say Chloe spent X
Then Amy spent 60% more so Amy spent
X+60% of X =X + 0.6X =1.6X
Becky spent 15% of what Chloe spent so amount spent by Becky =15% of X = .15X
Now, in total, they spent 0.15X+ X + 1.6X =2.75X which is given as £55
So , X=55/2.75 = 20
Amount spent by Amy = 1.6X = 1.6 *20 =£32

What is a slope ?
A line's slope is how steeply it slopes from LEFT to RIGHT. The slope of a line is determined by dividing its rise, or vertical change, by its run, or horizontal change. No matter which two locations on the line you choose, the slope of a line is always constant (it never varies).
The ratio of the increase in elevation between two points to the run in elevation between those same two points is referred to as the slope.
The slope-intercept form of an equation is used whenever the equation of a line is expressed in the form y = mx + b. M represents the line's slope. And b is the value of b at the y-intercept (0, b).
