Answer:
Total salary = $60,000
Step-by-step explanation:
Well I'm just going to make this short and easy... ok?
12,000=20%
20%x5 = 100%
hmmmm....
12,000 x 5 = ???
Answer = $60,000
Answer:
A = 388.58 cm^2
Step-by-step explanation:
For a cone whose base has a radius R, and a hypotenuse S, the area is:
A = pi*R^2 + pi*R*S
Where pi = 3.14
In this case, we can see that the diameter is: 15cm
Then the radius, half of the diameter, is:
R = 15cm/2 = 7.5cm
The hypotenuse is 9cm, then S = 9cm
A = 3.14*(7.5cm)^2 + 3.14*(9cm)*(7.5cm) = 388.575 cm^2
Rounding to two decimal places, we need to look at the third one, which is a five, so we need to round up:
A = 388.58 cm^2
x=5
Take the cube root of x cubed and 125
that gives you the value of x which is 5
81 a² - 25
is a difference of two squares and its factors are (9a + 5z³) and (9a - 5z³)
Step-by-step explanation:
The difference of two squares is a binomial of two terms each term is a square and the sign between the two terms is (-), its factorization is the product of two identical binomials with different middle signs
- a² - b² is a difference of two squares
- a² - b² = (a + b)(a - b)
∵ The binomial is 81 a² - 25
∵
= 9
∵
= a
∴ ![\sqrt{81a^{2}}=9a](https://tex.z-dn.net/?f=%5Csqrt%7B81a%5E%7B2%7D%7D%3D9a)
∵
= 5
∵
= z³
∴ ![\sqrt{25z^{6}}=5z^{3}](https://tex.z-dn.net/?f=%5Csqrt%7B25z%5E%7B6%7D%7D%3D5z%5E%7B3%7D)
- The two terms have square root
∵ The sign between them is (-)
∴ 81 a² - 25
is a difference of two squares
∵ Its factorization is two identical brackets with different
middle signs
∵ 81 a² = 9a × 9a
∵ 25
= 5z³ × 5z³
- The terms of the two brackets are 9a and 5z³
∴ 81 a² - 25
= (9a + 5z³)(9a - 5z³)
81 a² - 25
is a difference of two squares and its factors are (9a + 5z³) and (9a - 5z³)
