Answer:
a) yes b) no c) no
Step-by-step explanation:
In order to know this, remember something: to do the division between a number and a rational number like this and with zero to the left, the best way to solve them is converting these number to a natural number.
To do that, you only need to multiply the number by 10, 100, 1000, depending of how many decimals it have.
In case a) 0.05 has two decimals, therefore we multiply by 100:
0.05 * 100 = 5
However, when you do that, you have to do the same thing with the number in the dividend, in this case, 1.4:
1.4 * 100 = 140
So we can conclude that 1.4 you have to add a zero to do the division.
Case b) and c) do not apply, in both cases we multiply by 10 and we get this:
25.2 and 6,
26.1 and 3.
Answer:
B. 24inches
Step-by-step explanation:
<u>Original photo</u>
Width= 3inches
length= 5inches
<u>New photo</u>
width=
length= 40inches
3×8=24inches
5×<u>8</u>=40inches
The original are would be 48.
Since we know that the length and width are two consecutive even integers, we can model them as follows:
Width = x
Length = x + 2
This works because no matter what even number is put in for x, the length will also be even.
Now we know if we subtract 3 from the width, we have a new rectangle that gives us an area of 24 inches. Therefore, our new triangle has the following:
Width: x - 3
Length: x + 2
Area: 24
And we can plug this into the equation.
Length* Width = Area
(x + 2)(x - 3) = 24
x^2 - x - 6 = 24
x^2 - x - 30 = 0
This is not a quadratic that we can factor to show the following:
(x - 6)(x + 5) = 0
This gives us the answers of x = 6 and x = -5. Since a side can't be negative, we throw out the x = -5 and the answer is x = 6.
So if we go back to the original rectangle, we know:
Width = x = 6
Length = x + 2 = 8
Area = 6*8 = 48
Answer:
29/20
Step-by-step explanation:
Answer:
72 = x
Step-by-step explanation
154 is one of the degrees for that angle. And I seen 82 for the other one.
All you have to do is subtract 154 and 82 and you get 72.
