Josiah wants to ride his bicycle 42.5 miles this week. He has already ridden 18 miles.
If he rides for 5 more days, what is the average number of miles he would have to ride
each day to meet his goal?
Hello there! Allow me to help you!
|| ▼ Answer ▼ ||
4.9 miles
|| ✪ Solution ✪ ||
Step 1:
In this question, we are given the following:
Josiah wants to ride his bicycle 42.5 miles this week.
He has already ridden 18 miles. If he rides for 5 more days,
what is the average number of miles he would have to ride each day to meet his goal?
Step 2:
The details of the solution are as follows:
Total distance = 42. 5 miles
Distance ridden = 16 miles
Number of days left = 5 days
Let the number of miles that'll be ridden for each day be represented by x.
Hence, we have that,
[tex]5x+18=42.5[/tex]
[tex]5x=42.5-18[/tex]
[tex]5x=24.5[/tex]
Divide both sides by 5 we have that,
[tex]x=\frac{24.5}{5}[/tex]
[tex]x=4.9[/tex]
CONCLUSION:
The average number of miles he would have to ride each day to meet his goal = 4.9 miles
Hope this helps!
If you have any questions please ask.
The required average miles for him to ride for 5 days is 4.9 miles per day.
Given that,
Josiah wants to ride his bicycle 42.5 miles this week. He has already ridden 18 miles.
he rides for 5 more days, what is the average number of miles he would have to ride each day to meet his goal is to be determined
The average of the values is the ratio of the total sum of values to the number of values.
Here,
Josiah wants to ride his bicycle for a total of 42.5 miles,
he rides for 18 miles by now,
Remaining miles to ride = 42.5 - 18 = 24.5 miles
For 5 day is must ride for average = 24.5 / 5 = 4.9 miles per day.
Thus, the required average miles for him to ride for 5 days is 4.9 miles per day.

Find the area of the polygon.
Answer:
66 cm²
Step-by-step explanation:
As you know from the area formulas, the area of a triangle is equivalent to half the area of a rectangle with the same base and height. Another way to say that is the area of a triangle is equivalent to the area of a rectangle with the same base and half the height.
The triangle added to the side of the square is equivalent in area to a rectangle with the same 6 cm base (vertical dimension), and half the 10 cm height (horizontal dimension). That is, the total area of the polygon is the same as the area of one that is 6 cm high and 6+5 = 11 cm wide.
A = LW = (6 cm)(11 cm) = 66 square centimeters
__
If you want to figure the area more conventionally, it is the sum of the area of a 6 cm square and a 6×10 cm triangle:
6² +1/2(6)(10) = 36 +30 = 66 . . . square centimeters

3x-2(x+3)=4x-7
Please help me solve this
Answer:
x = 1/3
Step-by-step explanation:
First distribute the 2 to the (x + 3) and get 3x-2x-6 = 4x - 7.
Combine like terms and get x- 6 = 4x - 7.
Subtract x from either side and get -6 = 3x - 7
Now add 7 to both sides and get 3x = 1
Now divide 3 from both sides and get x = 1/3
A cylinder has a volume of 60cm what is the volume of a cone with the same radius and height.
Answer:
20 cm³
Step-by-step explanation:
Since the volume of a cylinder is 60 cm³, which we can express it as:
[tex]\displaystyle \large{\pi r^2 h=60}[/tex]
Keep in mind that [tex]\displaystyle \large{\pi r^2 h}[/tex] is the cylinder’s volume formula, and we want to find the volume of a cone with same radius and height. When they say same radius and height, they mean that the radius and height are the same as cylinders’.
But since no values of radius and height are given, we know that the volume of a cone is:
[tex]\displaystyle \large{\frac{1}{3}\pi r^2 h}[/tex]
Compare both formulas:
[tex]\displaystyle \large{\pi r^2h}[/tex] — cylinder’s volume
[tex]\displaystyle \large{\frac{1}{3}\pi r^2h}[/tex] — cone’s volume
See how they are quite similar except that cone’s volume has 1/3. That means cone’s volume is 1/3 of cylinder’s volume
Finding cone’s volume, multiply both sides by 1/3:
[tex]\displaystyle \large{\pi r^2h=60}\\\displaystyle \large{\frac{1}{3}\pi r^2h=\frac{1}{3}\cdot 60}\\\displaystyle \large{\frac{1}{3}\pi r^2h=20}[/tex]
Therefore, the volume of a cone with same radius and height from cylinder is 20 cm³.
__________________________________________________________
Summary
Volume (Cone) (1/3 of cylinder’s volume):
[tex]\displaystyle \large{V=\frac{1}{3}\pi r^2 h}[/tex]
Volume (Cylinder):
[tex]\displaystyle \large{V=\pi r^2h}[/tex]
They are quite related!

What is this answer and how?
Errors in the programming language Python can be broadly classified into two types, syntax errors, and logical errors. When writing a program the first time, the probability for syntax errors to arise is 0.3, that for logical errors is 0.5, and that for both errors to occur is 0.1.(a) Find the probability that no syntax errors occur.(b) Find the probability that no errors occur.(c) Find the probability that errors of any type occur.(d) The programmer found a syntax error in the code. What is the probability that there are also logical errors based on this finding?(e) Are the events of having syntax errors and logical errors independent? Also, explain why.
Answer:
Step-by-step explanation:
a( Pr(no syntax error) = 1-Pr(syntax error arises)
Pr(no syntax error) = 1 -0.3
Pr(no syntax error) = 0.7
b) Pr(no error occurred) = 1-Pr(both error occurred)
Pr(no error occurred) = 1-0.1
Pr(no error occurred) = 0.9
c) Pr(any type of error occurred) = Pr(syntax error occur)+Pr(logical)
Pr(any type of error occurred) = 0.5+0.3 = 0.8
d) Pr(syntax and logical) = Pr(syntax occur)+Pr(logical or syntax occur)
= 0.3+0.1
= 0.4
e) Independent event are events that occurs at the same time. The occurrence of one does not affect the other.
Pr(logical and syntax) = pr(syntax)×pr(logical)
Given
pr(syntax)×pr(logical) = 0.3×0.5 = 0.15
From the question, Pr(logical and syntax) = Pr(both error occurred) = 0.1
Since Pr(logical and syntax) ≠ pr(syntax)×pr(logical), this means that the errors are not independent
What is the slope intercept form of (-4,-5); and slope 1/2
Answer:
Step-by-step explanation:
Slope intercept form is y = mx + b where m is the slope and b is the y intercept.
We are given m = 1/2
Plug the point (-4,-5) in for x and y and the given slope in for m.
y = mx + b
-5 = 1/2(-4) + b
Now solve for b.
-5 = -2 + b
b = -3
Now plug m and b back in to get your slope intercept form.
y = 1/2x -3

line in slope-intercept form.
Answer:
[tex]y=6(x-8)-2\qquad\text{point-slope form}[/tex]
[tex]y=6x-50\qquad\text{slope-intercept form}[/tex]
Step-by-step explanation:
The equation of a line can be written in several forms. Two of the most-used forms are the point-slope and the slope-intercept forms.
The point-slope form requires to have one point (xo, yo) through which the line passes and the slope m. The equation expressed in this form is:
[tex]y=m(x-xo)+yo[/tex]
The slope-intercept form requires to have the slope m and the y-intercept b, or the y-coordinate of the point where the line crosses the y-axis. The equation is:
[tex]y=mx+b[/tex]
The line considered in the question has a slope m=6 and passes through the point (8,-2). These data is enough to find the point-slope form of the line:
[tex]\boxed{y=6(x-8)-2\qquad\text{point-slope form}}[/tex]
To find the slope-intercept form, we operate the above equation:
[tex]y=6x-48-2[/tex]
[tex]\boxed{y=6x-50\qquad\text{slope-intercept form}}[/tex]

Testing for a disease can be made more efficient by combining samples. If the samples from two people are combined and the mixture tests negative, then both samples are negative. On the other hand, one positive sample will always test positive, no matter how many negative samples it is mixed with. Assuming the probability of a single sample testing positive is 0.2, find the probability of a positive result for two samples combined into one mixture. Is the probability low enough so that further testing of the individual samples is rarely necessary?
Answer:
The probability of a negative is 0.64 but the probability of a positive is 0.36

The lid of a box is 43 cm² an area the volume of the box is 420 cm3 what is the height of the box?
Answer: 9.77 cm
Step-by-step explanation:
The volume of the box is length x width x height (V = l*w*h). The area of the lid of the box is the length x width (A = l*w). So, to find the height, you can change the equation to volume / (length x width) = height (V/(l*w) = h). Divide the volume by the area (420/43), to get the answer of 9.77 cm.

~~~PicklePoppers~~~the cost of computer was rs 65000 the price of computer was depreciated 12% compounded yearly how much amount was depreciated in 2 years?find it
Answer:
50336
Step-by-step explanation:
The cost deprecates by 12% each year. If we have to find how much it deprecated for 2 years, we will have to calculate how much is 12% of the current price, subtract it, then find how much is 12% equal to again and subtract it once again. Not sure if that's the smartest way to do it though.
Anyway, we have
65000, 12% of 65000 is equal to (65000 * 12) / 100 = 650 * 12 = 7800
After the first year, the price will be:
65000 - 7800 = 57200
Now we do the same thing:
12% of 57200 = 57200 * 12% = 57200 * 12/100 = 57200 / 1 * 12/100 = (57200 * 12) / 100 * 1 = 572 * 12 / 1 = 572 * 12 = 6864
After the second year the price will be:
57200 - 6864 = 50336

Here we are provided with an polynomial of degree 3 and we have to factorise it first and then we have to compute it's zeroes.
Given Polynomial:
x³ + 3x² - 10xTaking common x from all the 3 terms,
➝ x(x² + 3x - 10)
Factorising through Middle term factorisation,
➝ x(x² + 5x - 2x - 10)
➝ x{x(x + 5) - 2(x + 5)}
➝ x(x - 2)(x + 5)
Hence, Factorised !!
Now equating to 0 to find the zeroes of the poly.
➝ x(x - 2)(x + 5) = 0
That means,
x = 0x - 2 = 0x + 5 = 0So, the zeroes of the polynomial is 0, 2 or -5
And we are done....
