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.

Step-by-step explanation:

A function that models the total cost of running the air conditioner for the first 400 minutes is [tex]T=130 +0.25m[/tex].

Given the following data:

To write a function that models the total cost of running the air conditioner for the first 400 minutes:

First of all, we would write an equation to models the total cost of running the air conditioner for the first 400 minutes:

For the total time:

[tex]0.25m[/tex]

For the total cost:

[tex]T=130 +0.25m[/tex]

For the domain:

The value of m is the domain and it can be chosen from 0 to 130.

Domain (m) = [0, 130].

For the range:

A range represents the minimum and maximum value of a data set.

Thus, the value of T would be between 130 and 230.

Range = [130, 230].

For the intercept:

when x = 0, we have:

[tex]y=130 +0.25(0)[/tex]

y = 130.

Intercept = [0, 130]

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

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

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.

~Factor

x(x - 2)(x + 5)

Solve for the zero.

x(x - 2)(x + 5) = 0

We know that; x = 0, x - 2 = 0, and x + 5 = 0

x = 0

x - 2 = 0

x = 2

x + 5 = 0

x = -5

Best of Luck!

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:

Taking 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,

So, the zeroes of the polynomial is 0, 2 or -5

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]

[] The equation on the left, 292 [tex]\frac{1}{2}[/tex]  = 18 * 6 [tex]\frac{1}{2}[/tex]  * h

-> Volume is length times width times height. When we plug in all the values we have to solve for h (height) we get this equation.

[] The height is 2.5 inches

-> We will solve the equation above.

-> Multiply 18 by 6 and a half = 117

-> Divide 292 and a half by 117 = 2.5

-> The height is 2.5 inches or 2 [tex]\frac{1}{2}[/tex]inches

292 [tex]\frac{1}{2}[/tex] = 18 * 6 [tex]\frac{1}{2}[/tex]  * h

292 [tex]\frac{1}{2}[/tex] = 117h

[tex]\frac{292 \frac{1}{2} }{117}[/tex]= [tex]\frac{117h}{117}[/tex]

2.5 = 1h

h = 2.5 inches

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!

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

Answer:

Animals help pollinate flowers by eating them and depositing the seeds in different areas.

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

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
