Answer:

x, 2x+1, 4x+3, 8x+7

Step-by-step explanation:

If we call the first term x, then the subsequent term is 2x+1. Then, the next term is 2(2x+1)+1=4x+2+1=4x+3. Then, the fourth term is 2(4x+3)+1=8x+6+1=8x+7.

As a matter of fact, the nth term is given by $2^{n-1}x+2^{n-1}-1$ for starting term x.

Maria can clean the entire house in two hours. Her sister, Sasha, can clean the house in three hours. How long would it take for

MAXImum [283]

72 minutes

We require their hourly rate of work

Maria cleans $\frac{1}{2}$ the house in 1 hour

Sasha cleans $\frac{1}{3}$ of the house in 1 hour

let x be the time it takes both to clean the house

$\frac{1}{2}$ + $\frac{1}{3}$ = $\frac{1}{x}$

multiply through by 6x

3x + 2x = 6

5x = 6 ⇒ x = $\frac{6}{5}$

Together they can clean the house in 72 minutes

Pls explain the easiest way you an this will help me Thanks XD

The ratio is 4:3:1
let the ratio be 4x:3x:x
according to the question,4x+3x+x=40
8x=40
x=5
therefore amount of gravel=x*4=5*4=20 $m^{3}$
amount of sand=5*3=15 $m^{3}$
amount of cement=5*1=5 $m^{3}$

The ratio of three angle are 3:4:5 what is the highest angle of the triangle??

SCORPION-xisa [38]

The sum of the sides of a triangle is equal to 180º.
The three angles will be: 3x,4x and 5x.
we can suggest the following equation:
3x+4x+5x=180

12x=180
x=180/12
x=15

The angles would be:
3x=3(15)=45
4x=4(15)=60
5x=5(15)=75

Answer: the highest angle would measure 75º.
