Dmitri wants to cover the top and sides of the box shown with glass tiles that are 3 5 mm square How many tiles does he need 20 cm 15 cm
Answers
top = 20*15 = 300
sidesA = 2*20*9 = 360, is multiplied by 2 cause there are 2 sides like this
sidesB = 2*9*15 = 270, is multiplied by 2 cause there are 2 sides like this
so in total we have:
total = 300 + 360 + 270 = 930 cm^2
if we express this quantity in mm^2 we have:
1cm² = 100 mm²total = 930*100 = 93000 mm^2
so if the tiles are 5 mm^2 we need:
total tiles = 93000/5 = 18600
we need 18600 tiles of 5 mm^2

Answer:
a) attached the figure.
b) diagonal (d) = 13 inches
Step-by-step explanation:
The given figure is a rectangular box in which the length = 4 inches, width = 3 inches, and height = 12 inches.
a) Draw the figure and attached.
b) To find the diagonal from one of the box's top corners to the opposite corner of the base of the box, we have formula.
Diagonal length from top corner to corner of the base (d) =
We know that l = 4 , w = 3 and h = 12
Now plug in these values in the above formula, and find the diagonal.
d =
d =
d = 13 inches.

e=ellmore population
l is 12 times as e
l=12 times e
l=12e
comeined is 9646
l+e=9646
remember that l=12e so subsitue 12e for l
12e+e=9646
add like terms
13e=9646
divide both sdies by 13
e=742
linton=12e
subsitue
linton=12(742)
linton=8904
linton's population is 8904 peple

The given pictures show the remaining slices in each pie in gray.
What is the fraction?
In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Number of slice ate in pumpkin pie = 2/8
Number of slice ate in pecan pie = 3/8
Total number of slice pie ate
= 2/8+3/8
= 5/8
The portion of the pies Dakota’s family ate on Thanksgiving is 5/8. Therefore, option B is the correct answer.

Answer:
The fractional change is % .
Step-by-step explanation:
Given as :
The original fraction =
Where numerator = x
Denominator = y
According to question
The numerator decreased by 50%
Let The new numerator = x' = x - 50% of x
I,e x' = x ( 1 - )
Or, x' = x ()
Or, x' = x
or, x' = .........A
Again
The new denominator = y' = y - 25% of y
i.e y' = y (1 - )
Or, y' = y ()
Or, y' = y ()
Or, y' = ............B
So, The new fraction = =
Or, =
So, The fractional change = × 100
Or, The fractional change = × 100
Hence, The fractional change is % . Answer
