Starting at home, Ishaan travel uphill to the grocery store for 12 minutes at just 15 mph. He then traveled back home along the same path downhill at a speed of 30 mph. What is his average speed for the entire trip from home to the grocery store and back?
Answer:
20 mph
Step-by-step explanation:
Average speed is given as total distance traveled divided by total time taken:
S = d / t
Let us find the total distance traveled.
He traveled 12 minutes (0.2 hours) at a speed of 15 mph. The distance to the grocery store is therefore:
d = s * t
d = 15 * 0.2 = 3 miles
He travels the same distance to get back home, this means that his total distance traveled is 6 miles.
Let us calculate the time taken to get home from the grocery store:
t = d /s
t = 3 / 30 = 0.1 hour
Therefore, his total time is:
t = 0.2 + 0.1 = 0.3 hours
His average speed is therefore:
s = 6 / 0.3 = 20 mph

Answer: just graph these two equations
option a: y = 5x + 10
option b: y = 7.5x
and then tell at what number of event would having a card and not having a card is cheaper.
Step-by-step explanation:
the initial cost, $10, is your b value for the equation y = mx + b so yo would start here on the y axis. but for the second option you start at zero since you don't have a b value
Answer:
use this hope help you
option a: y = 5x + 10
option b: y = 7.5x
and then tell at what number of event would having a card and not having a card is cheaper.

Multiplication
Division
Addition
Subtraction
(In some places it might be called BEDMAS).
(9-3)+4(6-7)
Start by solving the brackets (parentheses).
6 + 4(-1)
Next, we must multiply 4 by -1.
6 + (-4)
This can be written as:
6 - 4

Which phrase represents the algebraic expression 3p+6/7p-9
Answer:
The answer is the sum of three times a number and six, divided by the difference of seven times the number and nine
Step-by-step explanation:
3p = three x a number
7p = seven x a number
3p+6 = sum of three x a number plus six
7p-9 = difference of seven x the number minus nine
(3p+6)/(7p-9) = sum of three times x number plus six, divided by the difference of seven x the number - nine
Which equation has the steepest graph?
A. y = 10x-5
B. y=3/4x-9
c. y = -14x+1
D. y = 2x + 8
The equation that has the steepest slope is y = -14x + 1
What is a slope?A slope is the ratio of the change in the y-coordinates to the change in the x-coordinates of a line segment.
Analysis:
A line is said to be the steepest if it has the highest absolute value of the gradient or slope.
From the equations, the coefficient of x in the equations is taken as the slope. y = -14x+ 1 is the equation with the highest absolute value 14. The absolute value means ignoring the minus sign, since it indicates a negative slope.

Answer:
y=-2/5x-6
Step-by-step explanation:
The line crosses the y axis at -6 so the y intercept is -6. The line of the graph goes down 4 and right 10 so the slope is -4/10 which is equal to -2/5 when simplified.
Answer:
y= -2/5x -6
Step-by-step explanation:
The slope is 2/5, because slope is rise over run, and the two points rise 2, and run 5. The y intercept is -6, because the line crosses the y axis at -6. Slope intercept form is y= mx+b, where x and y are the points, and slope is m, and b is y intercept. So the equation is y= 2/5x -6. HOPE THIS HELPS!! :D This is a negative slope too, so the slope is negative.
n a group of 60 students, 18 students take algebra I, 20 students take Algebra II, and 10 students take both subjects. How many students don’t take either of these subjects?

Answer:
32 students take neither of the subjects
Step-by-step explanation:
If we add the 20+18 we get 38. But 10 of the students are counted twice. So subtract 10 from 38 to get 28. This way each of the students that take both subjects are only counted once. Then, we take the total number of students, 60 and subtract the 28 students taking algebra classes to get 32 students.

Find the perimeter of a circle whose radius is 3.5cm. (Take pi = 22/7)
Answer:
P = 44
Step-by-step explanation:
The formula for the perimeter (circumference) of a circle is;
C = πd
C = 2πr
C = 2π (3.5)2
C = 2π7
C = 2 * 22/7 * 7
C = 2 * 22
C = 44

Answer:
SA = 1404.4 cm²
Step-by-step explanation:
Surface Area of cylinder = [tex]2\pi rh+2\pi r^2[/tex]
Where r = 7 cm, h = 25 cm
SA = [tex]2(3.14)(7)(25) + 2(3.14)(7)^2[/tex]
SA = 1099.56 + 2(3.14)(49)
SA = 1099.56 + 307.9
SA = 1404.4 cm²
Find the range of the given function y = 5x + 2, where x > -2.
Answer:
{-3, 2, 7, ...... } is the range of given function.
Step-by-step explanation:
We are given that the function is defined as:
[tex]y = 5x + 2[/tex] where [tex]x > -2[/tex].
To find:
Range of the given function = ?
Solution:
First of all, let us have a look at the definition of Domain and Range.
Domain of a function f(x) is the set of input that is valid i.e. the value of x which are valid.
For example, in the given question, x > -2 i.e. x can be any value from the set {-1, 0, 1, 2, ......} is the domain of given function.
Range of a function f(x) is the set of output that is valid according to the input given.
For the given equation, let us put the value of x one by one and try to find out the value of y.
Putting x = -1 first:
[tex]y = 5 \times -1+2\\\Rightarrow y=-3[/tex]
Putting x = 0:
[tex]y = 5 \times 0+2\\\Rightarrow y=2[/tex]
Putting x = 1:
[tex]y = 5 \times 1+2\\\Rightarrow y=7[/tex]
So, the range is : {-3, 2, 7,......}

The mean sustained wind velocity, v, can be determined by the equation v = 6.3 StartRoot 1013 minus p EndRoot, where p is the air pressure, in millibars, at the center of the hurricane. What is the approximate air pressure at the center of a hurricane when the mean sustained wind velocity is 64 meters per second?
Answer:
909.8 millibars.
Step-by-step explanation:
The mean sustained velocity, v be determined by the equation:
[tex]v=6.3\sqrt{1013-p}[/tex], where p is the air pressure, in millibars, at the center of the hurricane.
Given that: v=64 meters per second, we are to find the value of p.
[tex]64=6.3\sqrt{1013-p}\\$Square both sides to eliminate the square root sign\\(64)^2=(6.3\sqrt{1013-p})^2\\4096=39.69(1013-p)\\$Divide both sides by 39.69$\\\dfrac{4096}{39.69}=1013-p\\ $Therefore:$\\p=1013-\dfrac{4096}{39.69}\\\\p=909.8$ millibars[/tex]
The approximate air pressure at the center of a hurricane when the mean sustained wind velocity is 64 meters per second is 909.8 millibars.
