r-ruslan [8.4K]

Answer:

96 square units

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo.

My answer:

  • The length of the large rectangle is: 5
  • The width of the large rectangle is: 7

=> Area of the large rectangle = length × width  = 7*5 = 35 square units

  • The length of the middle rectangle is: 7
  • The width of the middle rectangle is: 4

=> Area of the middle rectangle = length × width  = 7*4 = 28 square units

  • The length of the small rectangle is: 7
  • The width of the small rectangle is: 3            

=> Area of the small rectangle = length × width  = 7*3 = 21 square units

Area of top and the bottom triangles =2* \frac{1}{2}bh  = 4*3 =12  

Total surface area = 35 + 28 + 21 + 12 = 96 square units

It is possible for two different inputs to give you the same output. For example, -2 and 2 produce the same result: 5.

it is not possible to derive two different outputs from the same input. This is because a) y=x^2+1 is a function making it impossible to have two outputs and b) for each value, if  you square it, you only get one value, then adding one, making it one certain value.

zloy xaker [14]

Answer: 258023743333miles³

Step-by-step explanation:

Volume of a sphere = 4/3πr³.

where,

π = 3.14

r = radius = 3950

Volume of a sphere = 4/3πr³.

= 4/3 × 3.14 × 3950³

= 4/3 × 3.14 × 61629875000

= 258023743333miles³

The volume of our planet if we assume that it is a sphere with the radius 3,950miles will be 258023743333miles³

grin007 [14]

The percent error is calculated by the formula Absolute Value of (Error - Actual / Actual then times 100).

In this case the Error value was 76, and the Actual was 80.

So, set up the expression

I(76 - 80)/80 x 100I

I-4/80 x 100I

I-400/80I

I-5I

5

The percent error was 5 percent, since that was how much her estimation differed from the actual amount.

Bingel [31]

Answer:

4y + 48 - 16x = 0        ~Solve for y~

4y = -48 + 16x

y = -12 + 4x

The slope is 4.

We'll use the point (1, 4) and m = 4.

Plug these into the equation: y - y1 = m(x - x1)

y - 4 = 4(x - 1)

y - 4 = 4x - 4

y = 4x
