8) A 7-inch apple pie sells for $4. What is its cost per square inch (in2)?
Round to the nearest cent.

Answers

Answer 1

Answer:

A = pi * r^2

A = 3.14 * 3.5^2

A = 38.465 sq. in.

4 / 38.465 = 0.1048 = $0.10 per sq. in.

What is an equation of the line that passes through the points (4,-2) and (8,-7)?

Answers

Answer:

the slope-intercept form for any line is y = mx + b, where m is the slope and b is the y-intercept.

 

now, let's calculate the slope:

 

=  

 

here is the equation we currently have solved: y = x + b

 

now we have to solve for the y-intercept. to do this, we substitute one of the given points into the equation, and solve for b.

 

let's use (8, 2). in this ordered pair, the 8 is the x, and the 2 is the y.

 

2 = 8 + b

2 - 8 = b

b = -6

 

and now we have our final equation!  

 

y = x - 6

 

hope this helped! please let me know if you are confused about anything i did smiley

Step-by-step explanation:

Answer:

y = -5/4x + 3

Step-by-step explanation:

Find the slope first:

m = (y2 - y1)/ (2 - x1)m = (-7 + 2)/(8 - 4) = -5/4

Use point-slope form and the coordinates of one of the points:

y - y1 = m(x - x1)y - (-2) = -5/4(x - 4)y + 2  = - 5/4x + 5y = -5/4x + 3

What are fractions?

A fraction is referred to as the portion of a whole in mathematics. For instance, if a pizza is cut into four equal pieces, each one is represented by a quarter. Fractions make calculations quicker and easier by making it easier to distribute and judge numbers.

Solution:

First day patrick walked = 3/5 miles

Second day patrick walked = 5/7 miles

Third day he walked = half of first day

                                 = 1/2 ×3/5

                                 = 3/10 miles

fourth day he walked = first two days distances

                                 = 3/5 ₊ 5/7

                                 = 46/35 miles

Total distance he walked = 3/5 ₊ 5/7 ₊ 3/10 ₊ 46/35

                                       = 3 miles

Hence total distance he walked is 3 miles.

If two angles are complementary, find the measure of each of angle.

Answers

Answer:

here's the answer to your question

Answer:

One angle is 70 degrees and the other one is 20 degrees

Step-by-step explanation:

If two angles are complementary, that means that they both add up to 90 degrees.

You have to use algebra to solve this bc you don't have the actual numbers.

So you can use the equation...

7f + 2f = 90

Solve for f, and then substitute the f back into the equation to find the measure of each angle.

7f + 2f = 90

9f = 90

f = 10

Substituting the 10 back in

7f = 7(10) = 70

2f = 2(10) = 20

point (10,-1) will be in quadrant

Answers

Answer:

4

Step-by-step explanation:

The first value (10) is the x value. 10 is positive so the point is on your right. The second value (-1) goes down below the x axis. because it is minus. right and down means you are in the 4th quadrant.

Answer:

IV

Step-by-step explanation:

In the picture below, it shows the model of all quadrants. Since the point (10, -1) has a positive as the x, you can eliminate quadrant II and III. The ones left are I and IV. Since y is a negative, you eliminate I because it is only positives while IV has a negative as it's y.

Bronson is ordering a sundae at a restaurant, and the server tells him that he can have up to four toppings: butterscotch sauce, caramel, peanuts, and strawberries. Since he cannot decide how many of the toppings he wants, he tells the server to surprise him. If the server randomly chooses which toppings to add, what is the probability that Bronson gets just butterscotch sauce, peanuts, and strawberries

Answers

Answer:

20%

Step-by-step explanation:

if zero toppings is an option, then there would be 5 possibilities for toppings

0,1,2,3,or 4

the server randomly chose 3 toppings so that would be one out of 5 or 20%.

(If the server did not have the option to put zero toppings on then there would be only 4 options 1,2,3, or 4 toppings and the correct answer would be one out of 4 or 25%.)

What are the ordered pairs of the
solutions for this system of equations?
f(x) = x2 – 5x + 3; f(x) = -3

Answers

Start by writing the system down, I will use [tex]y[/tex] to represent [tex]f(x)[/tex]

[tex]y=x^2-5x+3\wedge y=-3[/tex]

Substitute the fact that [tex]y=-3[/tex] into the first equation to get,

[tex]-3=x^2-5x+3[/tex]

Simplify into a quadratic form ([tex]ax^2+bx+c=0[/tex]),

[tex]x^2-5x+6=0[/tex]

Now you can use Vieta's rule which states that any quadratic equation can be written in the following form,

[tex]x^2+x(m+n)+mn=0[/tex]

which then must factor into

[tex](x+m)(x+n)=0[/tex]

And the solutions will be [tex]m,n[/tex].

Clearly for small coefficients like ours [tex]5,6[/tex], this is very easy to figure out. To get 5 and 6 we simply say that [tex]m=3, n=2[/tex].

This fits the definition as [tex]5=3+2[/tex] and [tex]6=2\cdot3[/tex].

So as mentioned, solutions will equal to [tex]m=3, n=2[/tex] but these are just x-values in the solution pairs of a form [tex](x,y)[/tex].

To get y-values we must substitute 3 for x in the original equation and then also 2 for x in the original equation. Luckily we already know that substituting either of the two numbers yields a zero.

So the solution pairs are [tex](2,0)[/tex] and [tex](3,0)[/tex].

Let Z be the standard normal random variable. Use a probability calculator to answer the following questions: What is the probability Z will be within one standard deviation of average?

Answers

Answer:

0.6826 = 68.26% probability Z will be within one standard deviation of average.

Step-by-step explanation:

Normal Probability Distribution

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

What is the probability Z will be within one standard deviation of average?

This is the p-value of Z = 1 subtracted by the p-value of Z = -1.

Z = 1 has a p-value of 0.8413.

Z = -1 has a p-value of 0.1587.

0.8413 - 0.1587 = 0.6826

0.6826 = 68.26% probability Z will be within one standard deviation of average.

Solve the right triangle given that mZA= 30°, mZC = 90°, anda = 15. Round your result to one decimal place.​

Answers

Answer:

[tex]\angle B = 60^o[/tex]

[tex]b =17.3[/tex]

[tex]c = 20[/tex]

Step-by-step explanation:

Given

[tex]a= 15[/tex]

[tex]\angle A = 30^o[/tex]

[tex]\angle C = 90^o[/tex]

See attachment for illustration

Required

Solve the triangle

First, we calculate the measure of B

[tex]\angle A + \angle B + \angle C = 180^o[/tex] --- angles in a triangle

[tex]30^o + \angle B + 90^o = 180^o[/tex]

Collect like terms

[tex]\angle B = 180^o-90^o-30^o[/tex]

[tex]\angle B = 60^o[/tex]

Solve for (c) using sine function

[tex]\sin(30) = \frac{a}{c}[/tex]

Make c the subject

[tex]c = \frac{a}{\sin(30)}[/tex]

Substitute known values

[tex]c = \frac{10}{0.5}[/tex]

[tex]c = 20[/tex]

Solve for (b) using Pythagoras

[tex]c^2 = a^2 + b^2[/tex]

This gives:

[tex]20^2 = 10^2 + b^2[/tex]

[tex]400 = 100 + b^2[/tex]

Collect like terms

[tex]b^2 =400 - 100[/tex]

[tex]b^2 =300[/tex]

Take square roots

[tex]b =17.3[/tex]

Answer:

[tex]1,814,400[/tex]

Step-by-step explanation:

The number of ways to arrange a word with [tex]d[/tex] distinct digits is each to [tex]d![/tex]. Since there are 10 letters, there are [tex]10![/tex] permutations initially formed.

However, there is one letter that is repeated, S. We need to account for that fact that switching the placement of the S's does not change the word, as they still appear the same. Therefore, divide [tex]10![/tex] by the number of ways you can arrange the 2 S's, which is simply [tex]2![/tex]. Therefore, our answer is:

[tex]\frac{10!}{2!}=10 \cdot 9\cdot 8\cdot 7\cdot 6\cdot 5\cdot 4\cdot 3=\boxed{1,814,000}[/tex]
