Answer:
[tex]-\dfrac{1}{4}[/tex]
Step-by-step explanation:
Given two points (-9,-6) and (3,-9). The slope of the line through the points is determined by the formula:
[tex]Slope, m=\dfrac{y_2-y_1}{x_2-x_1} ,$ where (x_1,y_1)=(-9,-6), (x_2,y_2)=(3,-9)\\$Therefore:\\ m=\dfrac{-9-(-6)}{3-(-9)}\\=\dfrac{-9+6}{3+9}\\=\dfrac{-3}{12}\\\\m=-\dfrac{1}{4}\\[/tex]
The slope of the line through the points (-9,-6) and (3,-9) is [tex]-\dfrac{1}{4}[/tex]
Answer:
the slope of the line through the points (-9,-6) and (3,-9) is [tex]-\dfrac{1}{4}[/tex]
Step-by-step explanation:
Given that,
Points (x₁ , y₁) is (-9,-6) respectively and
( x₂ , y₂) is (3,-9) respectively.
The slope of the line through the points is determined by the formula:
[tex]Slope, m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
where x₁ = -9
y₁ = -6
x₂ = 3
y₂ = -9
Therefore:
[tex]\\ m=\dfrac{-9-(-6)}{3-(-9)}\\=\dfrac{-9+6}{3+9}\\=\dfrac{-3}{12}\\\\m=-\dfrac{1}{4}\\[/tex]
Therefore, the slope of the line through the points (-9,-6) and (3,-9) is [tex]-\dfrac{1}{4}[/tex]

Your goal is to design a new shape for a cereal container that will hold the same volume of cereal as a standard ceareal box and costs as little as possible to make. Assume that cardboard costs $0.05 per square inch. How cheaply can you package cereal?
These figures are available.
* triangular prism
* rectangular prism
* cube
* pyramid
* cone
* cylinder
* sphere
You need to keep the volume the same as the original, the surface area has to be less, and the price has to be the cheapest. The original volume was 192in^3. The surface area was 272in^2.
Answer:
$14.50
Step-by-step explanation:
To calculate the cost for manufacturing a standard cereal box, we must take in account its surface area. The volume will be used to estimate the amount of cereal, the box can contain. The box is a cuboid as standard cereal boxes are cuboid.
So, we will consider the surface area. Given are:
Length- 8 inches
Width- 3 inches
Height- 11 inches
We will find the surface area as : 2lw + 2wh +2lh
= (2x8x3) + (2x3x11) + (2x8x11)
= 48 + 66 + 176 = 290 square inches
Given is - the cost of manufacturing the box is $0.05 per square inch.
So, cost of manufacturing the box with 290 square inches area =
0.05 x 290 = $14.50
The answer is $14.50
Select the expression that is equivalent to 48 + 12.

Two ships leave the same port. Ship A travels at a constant speed of 30 km/h. Ship B travels at a constant speed of 37 km/h. The angle between their paths 62 degrees. How far apart are the two ships from eachother three hours later?
Answer:
The distance between them is 105.07 km
Step-by-step explanation:
First we need to find the distance travelled by each ship.
To find this distance, we should use the formula:
distance = speed * time
For ship A, we have:
distance1 = 30 * 3 = 90 km
For ship B, we have:
distance2 = 37 * 3 = 111 km
Now, to find the distance between the ships, we can use the law of cosines, where a, b and c are the respectively the distance travelled by ship A, the distance travelled by ship B and the distance between them:
c^2 = a^2 + b^2 - 2*a*b*cos(62)
c^2 = 90^2 + 111^2 - 2*90*111*0.4695
c^2 = 11040.39
c = 105.07 km
The distance between them is 105.07 km

Complete Question
The area of grandiose rectangular painting is 56 in.² the width of the painting is 7 inches what is the diagonal of the painting
Answer:
The diagonal of the rectangular painting is [tex]z = 10.63 \ m[/tex]
Step-by-step explanation:
The diagram for this question is shown on the first uploaded image
From the question we are told that
The area is [tex]A = 56 \ in^2[/tex]
The width of the painting is [tex]w = 7 \ in[/tex]
Generally the area of the rectangle is mathematically represented as
[tex]A = l * w[/tex]
where [tex]l[/tex] the length which is mathematically evaluated as
[tex]l = \frac{A}{w}[/tex]
substituting value
[tex]l = \frac{56}{7}[/tex]
[tex]l = 8 \ in[/tex]
According Pythagoras theorem
[tex]z ^ 2 = l^2 +w^2[/tex]
Where z is the diagonal of the rectangular painting

If Rosetta sells her house and pays off the mortgage, how much should she receive (assuming there are no other costs associated with selling the house)?
$42,000
$50,000
$52,000
$60,000
Answer:
$50,000
Step-by-step explanation:
The computation of the amount received after paying off the mortgage is shown below
= Value of the house - mortgage amount
= $150,000 - $100,000
= $50,000
By deducting the mortgage amount from the value of the house we can get the amount received and the same is shown in the computation part
Since in the question it is given that the Rosetta sells her house and paid off mortgage so only these two items are considered and others are to be ignored
Answer:
B.) $50,000

Answer:
(8.47,0) (-0.47,0)
Step-by-step explanation:
y = a(x - h)² + k
y = a(x - 4)² - 20
-4 = a(0 - 4)² - 20
16 = 16a
a = 1
y = (x - 4)² - 20
x-intercepts: y = 0
(x - 4)² = 20
x - 4 = +/- 4.47..
x = 4.47+4, -4.47+4
x = 8.47, -0.47
Two parallelograms are similar. The base of the first is 12cm, and its height is 8 cm. Find the base of the second parallelogram if its height is 34 cm.
Answer:
The base of the second parallelogram is 51cm.
Step-by-step explanation:
If the parallelograms are similar, it means by applying the same scale factor to all the sides in one gives you the other. The question tells us the height of the first shape is 8cm and the height of the second shape is 34cm. That means the scale factor is:
[tex]\frac{34}{8}=4.25[/tex]
Apply this same scale factor to the base of the first shape to find the base of the second:
[tex]12 \times 4.25=51[/tex]

A restaurantis planning to make changes to its menu. In order to decide which potential menu items are most popular with the city's population, the owners will conduct a survey. Which survey methods would produce a representative sample of the city's population
Answer:
Simple random sampling survey method
Step-by-step explanation:
A simple random sampling is an unbiased survey technique Hence it will represent all the parts of the city's population.
In statistics, a simple random sample is a subset of individuals (a sample) chosen from a larger set (a population). Each individual is chosen randomly and entirely by chance, such that each individual has the same probability of being chosen at any stage during the sampling process
Marcus builds kites for a 14 day summer kite festival he plans to give away about the same number of kites each day he gives away 492 kites the first two days did Marcus stick to his plan?
Answer:
He did not stick to plan; he does not have enough kites.
Step-by-step explanation:
A key information is missing from the question, the number of kites that Marcus made.
After a quick web search, I have found that, in this problem, Marcus has built 2,744 kites in total.
It is know that he gave away 492 kites in the first two days, in a 14 day festival, there are 7 two-day periods. The number of kites required for Marcus to keep that same rate throughout the whole festival is:
[tex]n=\frac{14}{2}=7 \\K=7*492\\K=3,444\ kites[/tex]
Therefore, Marcus did not stick to his plan since he would have needed 3,444 kites to give kites away at the same rate as he did for the first couple days. This could also be interpreted as Marcus giving away too many kites in the first couple days.
Residents of a small city voted on whether
to allow a developer to build a shopping
center. The number of votes in favor of the
shopping center was 3,400. The number of
votes against the shopping center was 15,600.
What percent of the voters were in favor of
building the shopping center?
What percent of the voters were against of
building the shopping center?
Add the two numbers together to find total votes:
3,400 + 15,600 = 19,000 total votes.
Divide votes for by total votes:
3,400 / 19,000 = 0.1789
Multiply by 100:
0.1789 x 100 = 17.89% voted for it.
Subtract the percent that votes for it from 100%
100% - 17.89% = 82.11% voted against it.
The answers probably need to be rounded, so 18% for, and 82% against.

9/10
of alien races think invading Earth is a bad idea.
What percent of alien races think invading Earth is a bad idea?
Answer: 90%
Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.
So to write 9/10 as a percent, we need to find a fraction
equivalent to 9/10 that has a 100 in the denominator.
We can do this by setting up a proportion.
So we have [tex]\frac{9}{10} = \frac{n}{100}[/tex].
Now, we can use cross-products to find the missing value.
So we have (9)(100) which is 900 is equal to (10)(n) or 10n.
So we have 900 = 10n.
Next, dividing both sides of the equation by 10, we have 90 = n.
So, 9/10 is equal to 90/100 or 90%.
Answer:
90%
Step-by-step explanation:
9/10 times 100 is 90%
