Please help me with these and please have explanations

The floor plan of a room has a scale of 2.5 in. : 35 ft. In the drawing, the length of the room is 8 in. and the width of the ro

Oksi-84 [34.3K]

Well if I did my math correctly I do believe the perimeter should be 392 ft.

6÷2.5= 2.4
2.4×35=84

8÷2.5= 3.2
3.2×35=112

84×2
112×2
_____
392

you mult. by 2 because it's a room which usually has four walls and I imagined it being a rectangle.

Julia makes friendship bracelets. She was recently given nine bracelets from different people. At Christmas, she plans to give a

sergey [27]

Answer:

The number of bracelets with she start are 48.

Step-by-step explanation:

Given:

Julia was recently given 9 bracelets. She plans to give 1/3 of her bracelets. She will be left with 23.

Now, we need to find with how many did she start.

Let the bracelets with she start be $x$ .

She plans to give $\frac{1}{3}ofx$ = $\frac{x}{3}$ .

According to question:

$x-9-\frac{x}{3}=23$

On solving the equation:

$\frac{3x-27-x}{3} =23$

<em>Multiplying both sides by 3 we get:</em>

$3x-27-x=69$

$2x-27=69$

<em>Adding both sides by 27 and then dividing by 2 we get:</em>

$x=48$

Therefore, the number of bracelets with she start are 48.

The function g is defined as follows for the domain given. g(x) = 2 - 2x , domain = \{- 1, 0, 1, 2\} Write the range of g using

Musya8 [376]

Explanation:

The function is given below as

$g(x)=2-2x$

The set of domains is given below as

$\lbrace-1,0,1,2\rbrace$

Step 1:

Put x=-1

$\begin{gathered} g(x)=2-2x \\ g(-1)=2-2(-1) \\ g(-1)=2+2 \\ g(-1)=4 \end{gathered}$

Step 2:

Put x=0

$\begin{gathered} g(x)=2-2x \\ g(0)=2-2(0) \\ g(0)=2 \end{gathered}$

Step 3:

Put x=1

$\begin{gathered} g(x)=2-2x \\ g(1)=2-2(1) \\ g(1)=2-2 \\ g(1)=0 \end{gathered}$

Step 4:

Put x=2

$\begin{gathered} g(x)=2-2x \\ g(2)=2-2(2) \\ g(2)=2-4 \\ g(2)=-2 \end{gathered}$

Hence,

The range of g(x) using set notation will be

$\Rightarrow\lbrace4,2,0,-2\rbrace$

Hence,

The graph of g(x) is given below as

Please help :) Is the relationship shown by the data linear? If so model the data with an equation.

MrRissso [65]

Answer:

y-5=5/4(x-1)

Step-by-step explanation:

the slope is 1.25

m=y2-y1/x2-x1=10-5/5-1=5/4=1.25

y-5=(5)/(4)(x-1)=

y=(5)/(4)x+(15)/(4) this one is linear

it is a linear function and the

Wayne is using a waterproof covering to cover a storage locker that measures 4 ft wide, 10 ft tall, and 6 ft long. Which is the

Margaret [11]

Given the dimensions of locker box are length = 6 feet, width = 4 feet, and height = 10 feet.

Wayne wants to cover the box, so we need to find its total surface area. The box is in the shape of rectangular prism.

We know the formula for total surface area of rectangular prism is given as follows :-

$Total \;Surface \;Area = 2*(lw + wh + hl)$

T.S.A. = 2·(6 x 4 + 4 x 10 + 10 x 6) = 2·(24 + 40 + 60) = 2·(124) = 248 feet²

Surface Area = 248 squared feet

To cover the locker with waterproof covering, we needed to find the surface area of the box. As we multiplied two dimensions at a time in the formula, so the units are "squared feet".

Hence, option A is correct i.e. squared feet or ft².
