Answer:

0.1 = 1/10

0.64 = 64/ 100 = 16/25

0.7841 = 7841 / 10,000

0.67 = 67/100

0.53 = 53/100

0.26 = 26/100 = 13/50

0.6 = 6/10 = 3/5

0.42 = 42/100 = 21/50

Hope this helps you

In TVW if VW is three meters longer than TV, TW is 20 meters shorter than the sum of VW and TV, and the perimeter of TVW is 74 m

Artyom0805 [142]

Answer:

The length of VW is $25\ m$

Step-by-step explanation:

we know that

The perimeter of triangle TVW is equal to

$P=VW+TV+TW$

we have

$P=74\ m$

$74=VW+TV+TW$ -----> equation A

$VW=TV+3$ ----> equation B

$TW=(VW+TV)-20$ ----> equation C

substitute equation B in equation C

$TW=(TV+3+TV)-20$

$TW=2TV-17$ ----> equation D

substitute equation B and equation D in equation A

$74=(TV+3)+TV+(2TV-17)$

solve for TV

$74=4TV-14$

$4TV=74+14$

$4TV=88$

$TV=22\ m$

Find the value of VW

$VW=TV+3$ -----> $VW=22+3=25\ m$

Find the value of TW

$TW=2TV-17$ -----> $TW=2(22)-17=27\ m$

Which are the solutions of x2 = –11x + 4?

Zarrin [17]

For this case we have the following polynomial:

$x ^ 2 = -11x + 4$

Rewriting the polynomial we have:

$x ^ 2 + 11x - 4 = 0$

From here, we can solve the polynomial using the quadratic equation

We have then:

$x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}$

$x=\frac{-11+/-\sqrt{11^2-4(1)(-4)}}{2(1)}$

$x=\frac{-11+/-\sqrt{11^2+16}}{2}$

$x=\frac{-11+/-\sqrt{121+16}}{2}$

$x=\frac{-11+/-\sqrt{137}}{2}$

Therefore, the solutions are:

$x=\frac{-11+\sqrt{137}}{2}$

$x=\frac{-11-\sqrt{137}}{2}$

I NEED HELP PLEASE!!!! It's due

Kryger [21]

The answer would be A: 45, this is true because you need to look at it from a logic perspective and not only that but think within the box instead of outside because the answer is within their choices
