Well first you should know that 4/10 is simplified to 2/5 so that part is correct
But to know of the rest is correct , add the Fractions
so the common denominator will be 8 so 1/2 will become 4/8 + 3/8 = 7/8 but 7/8 does not equal 4/10
The denominator. Say for instance, you have 4/12 and 1/6. They are equivalent.
Answer:
B
Step-by-step explanation:
And arithmetic sequence is a sequence in which the difference between each of the numbers are constant.
It is not A, because the difference between 3 and 9 is positive 6, and the difference between 9 and 81 is positive 72.
It is not C, because the difference between 4 and 1 is -3, and the difference between 1 and 4 is positive 3.
It is not D, because the difference between 2 and -2 is -4, and the difference between -2 and 2 is positive 4.
And it is B because the numbers maintain a constant difference between each other, which is -3.
Answer:
20 m
Step-by-step explanation:
Given that :
Scale of 1 : 50 is used to make a model
If the model has a height of 40 cm ; the height of the house is:
Then, the actual height of the house is (40 * 50) = 2000 cm
Thus the height of the house in metre is :
100cm = 1 meter
2000 cm = 2000 / 100
2000 cm = 20 meter
Height of house in meter = 20 meter
88 feet
<span>√</span>484=22
Perimeter is l+l+l+l
22+22+22+22=88
