Answer:
Option C (72)
Step-by-step explanation:
In the figure attached we can see a rectangle ABCD with length 12 cm and width 9 cm.
A triangle PEF with height BE and base EF.
Since side AE = 3 cm, so side EB = EC = 9 - 3 = 6cm
and EF = AD = 12 cm
Now we will find the area of of the parts of the card that are not shaded.
Area of parts that are not shaded = Area of rectangle - area of shaded triangle
= (12×9) -
= 108 -
Option c) 72 cm² is the area of non shaded part.
Hope this helps!! -Mina
Answer:
18/40
Step-by-step explanation:
1. Find a common denominator
8, 16, 24, 32, 40
5, 10, 15, 20, 25, 30, 35, 40
2/8 times 5= 10/40
1/5 times 8= 8/40
10/40 plus 8/40= 18/40
Answer:
D- The blackcaps will begin nesting at their wintering sites in Spain or the United Kingdom, resulting in a larger blackcap population migrating back to Germany after the breeding season has ended.
Step-by-step explanation:
By the inhabitants of Spain and the United Kingdom placing feeders out for the blackcaps, the birds in their nesting sites during the winter will have food to eat, meaning a bigger population of the Blackcaps when they return to their main home in Germany.
This best predicts the effect on the blackcap population if humans in the United Kingdom continue to place food in feeders during the winter.
Answer:
7680 rabbits
Step-by-step explanation:
Let y represent the number of rabbits after x days and let x represent the number of days. This is an exponential growth equation in the form:
![y=ab^x](https://tex.z-dn.net/?f=y%3Dab%5Ex)
Since there is an initial value of 26 rabbits on the farm and the rabbits double every 30 days, hence the equation becomes:
![y=26(2^{(\frac{x}{30} )})\\\\for\ 240\ days, i.e\ x=240:\\\\y=26(2^\frac{240}{30} )\\\\y=7680\ rabbits](https://tex.z-dn.net/?f=y%3D26%282%5E%7B%28%5Cfrac%7Bx%7D%7B30%7D%20%29%7D%29%5C%5C%5C%5Cfor%5C%20240%5C%20days%2C%20i.e%5C%20x%3D240%3A%5C%5C%5C%5Cy%3D26%282%5E%5Cfrac%7B240%7D%7B30%7D%20%29%5C%5C%5C%5Cy%3D7680%5C%20rabbits)
The complete question in the attached figure
we know that
[Area of her bedroom]=[11*10]+[12*8/2]+[10*6]------> 218 ft²
the answer Part A) is
Are needed 218 ft² of carpeting for the room
[perimeter of her bedroom]=[11+10+11]+[12]+[6+10+6]+[8]-------> 74 ft
the answer Part B) is
Are needed 74 ft <span>
of baseboards</span>
for the room
