Answer:

32 m^2

Step-by-step explanation:

First find the real dimensions of the dining hall

The scale factor is 4m /3 cm

6 cm * 4m / 3cm = 8 m

3 cm *  4m / 3cm = 4 m

The area of the dining hall is

A = l*w

A = 8m * 4m = 32 m^2

Nimfa-mama [501]

Answer:

x=4

Step-by-step explanation:

1. 7x+56=14x+28 using distributive property (with the number of stes you need to have, this may count as 2)

2. 56=7x+28 by subtracting 7x from each side

3. 28=7x by subtracting 28 from both sides

4. x=4 by dividng by 7

5. plug back into equation

7(4)+56=14(4+2)

28+56=14(6)

84=84

A tower casts a shadow 11 feet long the distance from the top of the tower to the end of the the shadow is 61 feet how many feet
Jobisdone [24]
This is very easy!! I have attached a picture I have drawn if you are a visual learner... well, everything else like computations is here. 
.
This is the PYTHAGOREAN THEOREM!!
.
If you don't know, it says that the lengths of the legs squared added together all equal the hypotenuse squared in a right triangle!!
.
And if you want to know why the "triangle" has a right angle... well,  are towers slanted? I mean, other than the Leaning Tower of Pizza. I mean Pisa.
.
So... we plug it in!!
.
Formula: a^2 + b^2 = c^2.
.
Plug it in: 11^2+ 61^2 = c^2
.
c^2 = 3842.
.
So now what?
.
SQUARE ROOT OF EVERYTHING!!
.
c = <span>√3842.
.
So? c = approximately 61.984.
.
Hope I helped!!</span>
