Mathematics
1 answer:
VashaNatasha [74]3 years ago
5 0

Answer:

Step-by-step explanation:

1.Rewrite the decimal number as a fraction with 1 in the denominator

2.Multiply to remove 1 decimal places. Here, you multiply top and bottom by 101 = 10

3.Find the Greatest Common Factor (GCF) of 4 and 10, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 2,

so the answer is

0.4= 2/5

Fantastic Middle School is building a park, in the shape of a square, with an area of 256 square feet. How much fence do they ne
frez [133]
A = a^2.....where " a " is the size of 1 side
A = 256

256 = a^2...take sqrt of both sides, eliminating the ^2
sqrt 256 = a
16 = a

so each side is 16 ft....now we find the perimeter
P = 4a....where " a " is the size of each side
P = 4(16)
P =  64.......so they will need 64 ft of fencing <===

The sum of the first 10 terms of an AP is four times the sum of the first 5 terms then the ratio of the first term to the common
Mashcka [7]

Answer:

The ratio of the first term to the common difference is 1 : 2

Step-by-step explanation:

The rule of the sum of the AP is

S_{n}=\frac{n}{2}[2a+(n-1)d] , where

a is the first number

d is the common difference

n is the position of the number

∵ S_{10} = 4 × S_{5} ⇒ (1)

→ Find S_{10}  and S_{5}

∵ In S_{10} n = 10

∴ S_{10}=\frac{10}{2}[2a+(10-1)d]

∴ S_{10}=5[2a+9d]

∴ S_{10} = 10a + 45d ⇒ (2)

∵ In S_{5} n = 5

∴ S_{5}=\frac{5}{2}[2a+(5-1)d]

∴ S_{5}=2.5[2a+4d]

∴ S_{5} = 5a + 10d ⇒ (3)

→ Substitute (2) and (3) in (1)

∵ 10a + 45d = 4[5a + 10d]

∴ 10a +45d = 20a + 40d

→ Subtract 40d from both sides

∴ 10a + 45d - 40d = 20a + 40d - 40d

∴ 10a + 5d = 20a

→ Subtract 10a from both sides

∴ 10a - 10a + 5d = 20a - 10a

∴ 5d = 10a

→ Divide both sides by 5

∴ d = 2a

→ That means d is twice a or a is half d

∴ a : d = 1 : 2

The ratio of the first term to the common difference is 1 : 2

Which polynomial is factored completely?
Tasya [4]
D) 2g² + 5g + 4 is the polynomial that is factored completely.
This is because the terms in the polynomial do not have any common factors.

a) g⁵ - g can be factored into g(g⁴ - 1)
b) 4g³ + 18g² + 20g can be factored into 2g(2g² + 9g + 10)
c) 24g² - 6g⁴ cab be factored into 6g²(4-g²)
