Answer:
numbers are called-integer
fractional numbers are called-rational
Numbers less than zero are called ____negative__ numbers.
Step-by-step explanation:
The full exercise is attached.
Since JKLM is the result of the rigid motion of ABCD, the two quadrilaterals are congruent, especially their angles.
Therefore:
∡A = ∡J = 82°
∡B = ∡K = 104°
∡C = ∡L = 121°
∡D = ∡M = ?
Recall that the sum of the measure of the angles of a quadrilateral is 360°, and you will find:
∡M = 360 - (∡J + ∡K + ∡L)
= 360 - (82 + 104 + 121)
= 53
Hence, ∠M is
53°.
Answer:
18x^3+30x^2
Step-by-step explanation:
im smart.
This statement is true. For example:
![4x^2 +12x + 6 = 0](https://tex.z-dn.net/?f=4x%5E2%20%2B12x%20%2B%206%20%3D%200)
is an example of a quadratic equation in standard form. a, b, and c are all real numbers,
while a ≠ 0.
![x^{2} - 4=0](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20-%204%3D0)
is another example. a, b, and c are real numbers (b = 0), and a ≠ 0.
![4i x^{2} +2x - 6=0](https://tex.z-dn.net/?f=4i%20x%5E%7B2%7D%20%2B2x%20-%206%3D0)
would not be an example of a quadratic equation in standard form. a is not a real number.
![3x-4=0](https://tex.z-dn.net/?f=3x-4%3D0)
is not an example because a = 0.
Answer:
The number of 1/5 liter glasses that Lin can fill is ![7\frac{1}{2}](https://tex.z-dn.net/?f=7%5Cfrac%7B1%7D%7B2%7D)
Step-by-step explanation:
we know that
To find out how many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water, divided 1 1/2 by 1/5
so
![1\frac{1}{2} :\frac{1}{5}](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B2%7D%20%3A%5Cfrac%7B1%7D%7B5%7D)
Convert mixed number to an improper fraction
![1\frac{1}{2}=1+\frac{1}{2}=1\frac{1*2+1}{2}=\frac{3}{2}](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B2%7D%3D1%2B%5Cfrac%7B1%7D%7B2%7D%3D1%5Cfrac%7B1%2A2%2B1%7D%7B2%7D%3D%5Cfrac%7B3%7D%7B2%7D)
substitute
![\frac{3}{2} :\frac{1}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D%20%3A%5Cfrac%7B1%7D%7B5%7D)
Multiply in cross
![\frac{5*3}{2*1}=\frac{15}{2}=7.5](https://tex.z-dn.net/?f=%5Cfrac%7B5%2A3%7D%7B2%2A1%7D%3D%5Cfrac%7B15%7D%7B2%7D%3D7.5)
Convert to mixed number
![7.5=7+\frac{1}{2}=7\frac{1}{2}](https://tex.z-dn.net/?f=7.5%3D7%2B%5Cfrac%7B1%7D%7B2%7D%3D7%5Cfrac%7B1%7D%7B2%7D)
