Each rectangle is (18cm)(10cm)=180 square cm.
180 square cm/45 square cm=4. she cuts four triangles from each rectangle
(4 patches/rectangle)(32 rectangles)=128 patches
Answer=128 patches
Answer:
d.−1.4, 3.4
Explanation:
Given
Required
Determine the zeros
The best way to solve this is to apply the graphical method.
First, we plot the graph of:
<em>See attachment </em>
Next, we write out all values of x when the line crosses the y-axis.
From the attached graph, the points are (approximately):
Option (d) is the closest to the above values.
<em>Hence, the zeros are: -1.4 and 3.4</em>
In the 19th and 20th century, many Southeast Asian countries
suffered colonial domination by European powers. Thailand was the only
Southeast Asian state to escape colonial rule. The British and French decided
the country to be neutral territory and it remained independent.
<u>Answer</u>:
Delta, Forest, Plateau and stream are the natural regions.
<u>Explanation</u>:
Delta is the old stage of the running water landforms which is created at the mouth of the river. Forest is a group of trees formed in densely manner and Plateau is the landform which took several milion years to form. Stream is the running water system which originates from the glacial or mountain. Denver is one of the cities in the Colorado state and Georgia is a state in USA which is created by man made activities. North America comes under the category which is delineated by the humans.
Answer:
They found evidence of an impact crater in Mexico
Explanation:
The K-Pg boundary is the boundary that separates two periods, but also two eras. The two periods that are separated by this boundary are the Cretaceous and the Tertiary, while the two eras are the Mesozoic and the Cenozoic. The boundary is marked by a mass extinction, and the scientists started to hypothesize as to why it happened. There were numerous different theories, but a clue in Mexico, or rather right next to the Yucatan Peninsula, shed new light on it. The scientists found an impact crater, formed either by a large asteroid or a comet. Such an impact would have easily caused sudden and drastic changes on the Earth, killing of the majority of the species. This impact released such a big amount of energy that it killed everything in the surrounding area in seconds. On top of that, it caused an extremely hot wave of air across the whole planet, killing many more organisms. It managed to trigger most of the volcanoes to erupt, as well as the earthquakes, causing also very large tsunamis. The sunlight got blocked for quite some time from all the aerosols in the atmosphere as well. This resulted in a mass extinction of the dominant species, like the dinosaurs, but it opened up the terrain for the evolution of the others, like the mammals.
