From his home, Dan would have to walk due north to get to his friend Samuel's house and due east to get to his friend Cindy's house. It is 3 kilometers from Dan's house to Cindy's house and a straight-line distance of 5 kilometers from Samuel's house to Cindy's house. How far is Dan's house from Samuel's house?
The distance from Dan's house to Samuel's house is 4 km
The distance from Dan to Samuel house, Dan to Cindy house and Samuel to Cindy house forms a right angled triangle.
Distance from Dan to Samuel house = x, Distance from Dan to Cindy house = 3 km and Distance from Cindy to Samuel house = 5 km
Pythagoras theorem shows the relationship between the lengths of a right angled triangle.
Using Pythagoras theorem:
5² = x² + 3²
25 = x² + 9
x² = 16
x = 4 km
Hence the distance from Dan's house to Samuel's house is 4 km

Predict what you will see at the end of your experiment in part C. How would these results demonstrate fossilization? (Image just in case)
Answer:
The fossils would look weird and sometimes they might not be the exact shape as before because they've grown with the earth meaning they're going to come out of the ground go back under and what not, Its hard to tell how deep a fossil can be in the ground because of how many years ago it was because how much the earth has grown.

An angle measuring 60 degrees is measured as 62 degrees. What is the percentage error correct to 3 significant figures?
3.23%
3.33%
37.2%
35.5%
Answer:3.33%
easy
Step-by-step explanation:
A = true value = 60
B = estimated or measured value = 62
C = percent error
C = ( |A-B|/A ) * 100%
C = ( |60-62|/60 ) * 100%
C = (2/60)*100%
C = 0.0333*100%
C = 3.33%
Determine the x-intercept points of the function h(x) = (x – 5)(x – 6).
Answer:
(5,0),(6,0)
Step-by-step explanation:
The x-intercept occurs when h(x) = 0
∴ let 0 = (x – 5)(x – 6) [using the knowledge that for the
produc to be 0, one of terms
must be zero]
⇒ x - 5 = 0 ; x - 6 = 0 [solve for x in each case]
⇒ x = 5 ; x = 6
∴ the points of the x-intercept are (5, 0) & (6, 0)Check:
If we graph the line we can see whether the intercepts are truly (5, 0) and (6,0). As seen below in the Desmos graph, it is.

Answer:
Solve by multiplying a scale factor of 4 to each coordinate
Step-by-step explanation:
If the coordinate of J is dilated by a scale factor of 4, the resulting coordinate of the figure J' will be at (-48, 64)
Dilation of coordinatesDilation is a transformation technique used to change the size and shape of an object on a xy-plane.

Find the area and perimeter of
the parallelogram:
17ft
12ft
15ft
Answer:
Hi there!
Here is your answer...
The Area of the Parallelogram is:
[tex]204ft^{2}[/tex]The Perimeter of the Parallelogram is:
[tex]64ft[/tex]
Step-by-step explanation:
To find the Area of a Parallelogram you must first identify the Base and Height. In this instance the Base would be the top and bottom which we know are 17ft in length. The Height would be the dotted line that we know it 12ft tall. The next step would be to Multiply the Base by the Height. That would give us 204. After we add the correct units we have [tex]204ft^{2}[/tex].
To find the Perimeter we would simply add together all side lengths. We know that the top and bottom are equal to 17ft and the left and right are equal to 15 feet. This gives us 17+17+15+15. Which would equal 64, add the units and it becomes [tex]64ft[/tex].
Area=base x height
Perimeter = base + base + angle +angle
(angle is the side length.)

3. Dean has these cans of soup in his kitchen cabinet: 2 tomato, 3 chicken, 2 cheese, 2 potato, 1 beef. Dean will randomly choose one can of soup. Then he will put it back and randomly choose another can of soup. What is the probability that he will choose a can of beef soup both times? *
Answer:
2/20 or 0.1
Step-by-step explanation:
So we are given this data:
Tomato = 2
Chicken = 3
Cheese = 2
Potato = 2
Beef = 1
Total Chances (Sum Of All)
Total = 10
Beef is 1
To get beef soup one time it would be 1/10
what about 2 times
we can just multiply by 2*
so 1 / 10 * 2 = 2 / 20 or 0.1
The Answer would be 2/20 or 0.1

When would the tail of a comet appear to become longer?(1 point)
as it gets farther from Earth
as it gets closer to Earth
as it gets closer to the sun
as it gets farther from the sun
Answer:
As it gets closer to the sun
Step-by-step explanation:
just trust me
The tail of comet will appear to become longer : (c) as it gets closer to sun.
The tail of a comet becomes longer and more pronounced as it gets closer to sun. Comets are made up of ice, dust, and volatile gases. As a comet approaches the sun, the sun's heat causes the ices within the comet to vaporize, creating a glowing coma (a cloud of gas and dust) around the nucleus.
The solar wind and radiation pressure then push the gas and dust particles away from the coma, forming the tail that points away from the sun due to the solar wind's influence. This tail becomes more visible and elongated as the comet gets closer to the sun, making it a sight in night sky.
Therefore, the correct option is (c).
