Given : 4105.8

To find : what value does the 1 represent .

Solution : We have given 4105.8

We can see that 1 is at hundred place = 100 .

Expanded form : 4000 + 100 + 5+ $\frac{8}{10}$

Therefore, 1 represent the 100.

A triangle has a perimeter of 280 cm, and its side lengths are a, b and c respectively. If

Irina-Kira [14]

Answer:

The length of the sides are 64 cm, 96 cm and 120 cm.

Step-by-step explanation:

Perimeter of a triangle:

The perimeter of a triangle is the sum of it's sides.

A triangle has a perimeter of 280 cm, and its side lengths are a, b and c respectively.

This means that:

$a + b + c = 280$

a:b= 2:3

This means that:

$\frac{a}{b} = \frac{2}{3}$

$2b = 3a$

$b = \frac{3a}{2}$

b:c=4:5

This means that:

$\frac{b}{c} = \frac{4}{5}$

$4c = 5b$

$c = \frac{5b}{4}$

$c = \frac{5*3*a}{4*2} = \frac{15a}{8}$

At the original equation:

We replace b and c in function of a. So

$a + b + c = 280$

$a + \frac{3a}{2} + \frac{15a}{8} = 280$

Multiplying everything by 8

$8a + 12a + 15a = 280*8$

$35a = 280*8$

$a = \frac{280*8}{35}$

$a = 64$

Sides b and c:

Since we have a, we can find sides b and c:

$b = \frac{3a}{2} = \frac{3*64}{2} = 3*32 = 96$

$c = \frac{15a}{8} = \frac{15*64}{8} = 15*8 = 120$

The length of the sides are 64 cm, 96 cm and 120 cm.

If f(x) = x² - 2x, find:<br> f(6) = [?]<br><br> will give brainliest answer !!

Alina [70]

Answer:

$\boxed{f(6) =2 4}$

Step-by-step explanation:

Given function:

$f(x) = x² - 2x$

Solution:

ATP,it is that x = 6. So substitute 6 on the function.

$f(6) = 6 {}^{2} - 2(6)$

Simplifying using PEMDAS,we obtain:

$f(6) = 6 \times 6- 12$

$f(6) = 36 - 12$

$\boxed{f(6) =2 4}$

Hence,f(6) = 24.
