Plz help... again I just can’t

Goshia [24]

Answer:

$\frac{1}{6}$

Step-by-step explanation:

Because we are looking for the scale factor of the model to the bridge (model first), the scale factor will be less than one.

$\frac{5}{30}=\frac{1}{6}$

$\frac{6}{36} =\frac{1}{6}$

$\frac{9}{54} =\frac{1}{6}$

Each fraction ( $\frac{model}{bridge}$ ) can be simplified to $\frac{1}{6}$ . Therefore, the scale factor of the model to the bridge is $\frac{1}{6}$ .

Here is the question | | | | v

raketka [301]

Answer:

16.5 square feet

Step-by-step explanation:

The logo consists of

rectangle with sides of 3 ft and 1.5 ft;
trapezoid with bases 3 ft, 4 ft and height of 3 ft;
triangle with base of 1.5 ft and height of 2 ft.

The area of rectangle:

$A_{rectangle}=1.5\ ft\times 3\ ft=4.5\ ft^2$

The area of trapezoid:

$A_{trapezoid}=\dfrac{3\ ft+4\ ft}{2}\times 3 \ ft=3.5\ ft\times 3 \ ft=10.5 \ ft^2$

The area of triangle:

$A_{triangle}=\dfrac{1}{2}\times 1.5\ ft\times 2 \ ft=1.5\ ft^2$

Hence, the area of logo:

$A=A_{rectangle}+A_{trapezoid}+A_{triangle}=4.5\ ft^2+10.5\ ft^2+1.5\ ft^2=16.5\ ft^2$

Martin had M dollars initially. First, Martin spent 1/3 of his money. Then Martin spent 3/4 of what was left. Finally, Martin sp

Ilya [14]

Answer:

first he had M some unknown amount

then he had 2/3 M since he spent 1/3 M

then he spent 3/4 of the (2/3 M) so he had 1/4 of the ( 2/3M)

then he spent what was left $20 so $20 = 1/4 ( 2/3 M) now solve for M

and check by doing each step and figuring how much was spent and how much left.

another method 

let us consider the left amount be Y and total now of M dollar be X

then

Y = amount of money Nartin has left

Y = X - ( 1/3 ) ( X ) - ( 3/4 ) ( X - 1/3 X ) - 20

Y = X - 1/3 X - 3/4 X + 3/12 X - 20

Y = X - 4/12 X - 9/12 X + 3/12 X - 20

Y = X - 10/12 X - 20

Y = X - 5/6 X - 20

Y = ( 1 / 6 ) ( X ) - 20

hope it helped u buddy : )

Help! Simplify: (5/6)^2

aivan3 [116]

Answer:

.1147816 and the 6 is repeating

Step-by-step explanation:

What you do is you have to divide 5/6 first.

5/6=.83 and the 3 is repeating.

You will then square .83 to get:

.1147816 and the 6 is repeating as your answer.
