Answer: 13.5 Okay! Here's the method count the legs of the right triangle

The formula we'll use will be

A^2 + B^2 = C^2

In this case we're counting by twos

The base is 11 so we times it by itself =110

The leg is 8.5 so we going to times itself to make 72.25 add those together so 110+ 72.25 = 182.25 then we \|-----

182.25

Then you have got ur answer of 13.5

Step-by-step explanation:

Why isn't 20 over 100 proportional

Rina8888 [55]

It isn't proportional because it is not reduced to the lowest terms

Instead 20 over 100 = 1 over 5

Hope this helps!

Write an recursive formula for an, the nth term of the sequence 19,22,25, ....

ra1l [238]

Answer:

$T_n = T_{n-1}+3$ where n>1

Step-by-step explanation:

Given

$19,22,25, ..$

Required

Determine the recursive formula

The given sequence shows arithmetic progression (AP).

First, we calculate the common difference (d):

$d = 22 - 19 = 25 - 22$

$d = 3$

The recursive formula of an AP is determined using:

$T_n = T_{n-1}+d$ where $n>1$

Substitute 3 for d

$T_n = T_{n-1}+3$ where $n>1$

X+2y=9 and x=2y+1<br><br>helppppppppppppppppp meeeeereeer

skelet666 [1.2K]

Answer: y = 2

Step-by-step explanation:

we need to use systems of equations, basically since we know what x equals, we plug that into first equation so:

since x=2y+1,

we can say that:

(2y+1)+2y=9

then we solve this equation,

first we expand the brackets- 2y+1+2y=9,

then we combine like terms- 4y+1=9

then we take 1 away from both sides- 4y=8

then we divided both sides by 4

y=2

Hope this helps xx

the area of a window is 192 in squared. The width if the window is four inches more than half the length of the window. What are

Leya [2.2K]

Answer:

Length = 16 inches and width = 12inches

Step-by-step explanation:

A = 192 in² . The width is 4 + 1/2x. therefore let x = length

Area = LW

192 = x(4 + 1/2 x)

192 = 4x + 1/2x²

384 = 8x + x² Multiply each term by 2 to make a

384 + 16 = x² + 8x + 16 Complete the square

400 = (x + 4)²

$\sqrt{400} = \sqrt{(x + 4)^2}$

± 20 = x + 4

20 = x + 4 or -20 = x + 4

20 - 4 = x or -20 - 4 = x

16 = x or -24 = x reject the negative amount

Length = 16

width = 4 + 1/2(16); 4 + 8 = 12
