Amelia measured the elementary school and made a scale drawing. The scale of the drawing was 11 millimeters : 4 meters. If the schoolyard is 484 millimeters long in the drawing, how long is the actual schoolyard?

Answers

Answer: 176m

Step-by-step explanation:

First we have to convert the meters in the scale to millimeters

4m = 4*1000mm

Now we got the scale 11:4000

11x = 4000 * 484
x= (4000*484)/11
x = 4000 * 44
x = 176000mm = 176m

176 meters
Ex: In the drawing 484 millimeters so 44x11 millimeters: 176

BEST GETS BRAINLEST.A construction engineer needs to make 25 square concrete slabs with sides of length x feet and a height x - 3 feet. If the engineer can use at most 350,000ft^3 of concrete, what should the dimensions of each slab be, to the nearest foot?

a. Write an expression for the volume of all the slabs

b. What should x equal, to the nearest foot?

Answers

Answer:

x ≈ 118 ft

Step-by-step explanation:

To get an expression for the volume of all slabs, we can use the formula of volume of cuboid 'V', which is equal to the product of its length 'x', breadth 'x' and height 'x-3' i.e.

$V = x.x.(x-3)$

For 25 slabs,

$V = 25x.x.(x-3)$

Since, V cannot be more than 350,000 $ft^(3)$ , therefore,

$350000 = 25x^(2) (x-3)$

which can be written as:

either:

$350000 = 25x^(2)$

$x = \sqrt{ (350000)/(25)$

x ≈ 118 ft

or:

$x - 3 = 350000$

$x = 350003$

which is not possible.

Hence x should be 118 ft

We know that the given side lengths are x and the height is x.

Therefore, the area of the base = $A = x * x$

$Formula =\ \textgreater \ volume = length*width*height$

$To \ find \ the \ volume \ of \ 1 \ slab, \ multiply \ by \ the \ height$ $x -3$

$= x*x*(x-3)$

$Volume \ of \ 25 \ slabs =$ $25*x^2*(x-3)=350000$

$350,000/25 = 14,000$

$x^3 - 3x^2 - 14000$

$= 25.14$

$Rounded => x=25$

jackie is making a beaded bracelet. The bracelet will have no more than 12 beads. 1/3 of the beads on the bracelet will be green. What.other fractions could represent the part of the beads on the bracelet that will be green?

Answers

Answer:

$(1)/(3)$ , $(2)/(6)$ , $(3)/(9)$ and $(4)/(12)$

Step-by-step explanation:

We have that,

The fraction of the bracelet having green beads = $(1)/(3)$ .

Total number of beads must be no more than 12.

Thus, the maximum number of green beads can be $(1)/(3)* 12$ = $(12)/(3)$ = 4

So, the fractions of bracelet representing green beads will be,

$(1)/(3)$ , $(2)/(6)$ , $(3)/(9)$ and $(4)/(12)$

Since there could be no more than 12 the multiples of 1/3 untill a denominator of 12 are 2/6 3/9 and 4/12
