Davindra made a paper box that is 8 in. Long, 5 in. Wide, and 1 in. High. It is shaped like a rectangular prism. What is the surface area of the box? *
Answer:
106 in²
Step-by-step explanation:
Given that :
Davindra made a paper box that is 8 in. Long, 5 in. Wide, and 1 in. High.
Using the relation :
SA=2lw+2lh+2hw
Surface area :
2(lw + lh + hw)
l = 8 ; w = 5 ; h = 1
Surface area :
2(8*5 + 8*1 + 1*5)
Surface area :
2(40 + 8 + 5)
= 2(53)
= 106 in²
Discs of a radius 4cm are cut from a rectangular plastic sheet of length 84cm and width 24 cm
How many complete discs can be cut out?
The total area of the discs?
The total area of the sheet wasted?
Answer: 40
Step-by-step explanation:
Given
Radius of disc [tex]r=4\ cm[/tex]
The dimension of the sheet is [tex]84\times 24\ cm^2[/tex]
Area of a single disc
[tex]\Rightarrow a=\pi r^2=\frac{22}{7}\times 4^2\\\\\Rightarrow a=\frac{352}{7}\ cm^2[/tex]
Area of sheet
[tex]\Rightarrow A=84\times 24=2016\ cm^2[/tex]
No. of discs that can be cut off the sheet are
[tex]\Rightarrow n=\dfrac{A}{a}=\dfrac{2016}{\frac{352}{7}}=\dfrac{2016\times7}{352}\\\Rightarrow n\approx 40[/tex]
The total area of the disc is
[tex]\Rightarrow na=40\times\frac{352}{7}=2011.428\ cm^2[/tex]
Sheet wasted
[tex]\Rightarrow A-na=2016-2011.428=4.57\ cm^2[/tex]
7. Calculate the unit cost.
a) $1.85 for 4 kg of peaches
b) $16.99 for a 454 g package of cooked
shrimp
c) $2.99 for a 1.89 L bottle of juice
d) $283.28 for 22.5 m2 of flooring tiles
Answer:
Step-by-step explanation:
It cost $0.46 for 1 kg of peaches $.46/kg
It cost $12.6 for 1 m² of flooring tiles $12.6/1 m² of flooring tiles
It cost $1.6 for 1 L bottle of juice $1.6/L
dont know shrimp
The unit costs are:
(a) $1.85 for 4 kg peaches= $0.4625 per Kg
(b) $16.99 for a 454 g package cooked shrimp= $37.423 per Kg
(c) $2.99 for a 1.89 L bottle juice= $1.58 per L
(d) $283.28 for 22.5 m2 flooring tiles= $12.6 per m²
How to calculate unit value?In order to find the unit value of a quantity then divide the total cost by the quantity to get the unit price.
Unit price = total cost/ total number of quantity
here given
(a) $1.85 for 4 kg peaches
unit cost = total cost/ total number of quantity
= $1.85/4 Kg
=$0.4625 per Kg
(b) $16.99 for a 454 g package cooked shrimp
unit cost = total cost/ total number of quantity
= $16.99/454g
=$0.037 per gram
=$37.423 per Kg
(c) $2.99 for a 1.89 L bottle juice
unit cost = total cost/ total number of quantity
= $2.99/1.89L
=$1.58 per L
(d) $283.28 for 22.5 m2 flooring tiles
unit cost = total cost/ total number of quantity
=$283.28/22.5m²
=$12.6 per m²
Therefore the final unit costs are:
(a) $1.85 for 4 kg peaches= $0.4625 per Kg
(b) $16.99 for a 454 g package cooked shrimp= $37.423 per Kg
(c) $2.99 for a 1.89 L bottle juice= $1.58 per L
(d) $283.28 for 22.5 m2 flooring tiles= $12.6 per m²

Hi!
Speed=Distance x Time
So... 3 x 54 = 162
Hope this helps :)
Answer:
18km/h
Step-by-step explanation:
Well. Speed = Distance x Time
So if she travelled for 3 hours. In that time, she must have travelled 54km.
Average speed is given as kilometres per hour or km/h
So all we need to do is 54/3 which gives us 18km/h

Answer:
The missing are 8°, 16°, 24°.Let the missing angles be x, 2x, 3x.
X + 130° + 2x + 3x = 180°. (sum of angles is 180°)

Ms. Wang and her class are selling bags of cookies to raise money for a field trip.
Each bag weighs 140 grams and has 6 cookies.
Each cookie has the same amount of dough that weighs 14 grams.
Each cookie has the same amount of candy
If a bag of candy has 20 grams of Candy, how many bags of candy does the class need to make 18 cookies?
Answer:
9 bags of candy
Step-by-step explanation:
6 cookies at 14 grams each = 84 grams meaning the remaining grams of the 140 have to be the weight of the candy which = 56 grams (140-84). To find out how much candy is in one cookie divide 56 by 6 which = 9.33333. You then divide 20 by 9.3333 which = 2.14 (rounded to nearest 10th). Since you can get just over 2 cookies worth of candy per bag you only need half the number of cookies in bags of candy (9 bags)
Determine the slope of the line that passes through each pair of points. Write in simplest form. (3,8) and (1,5)
Answer:
y = 3/2x + 7/2
Step-by-step explanation:
First, you need to find the slope.
y2 - y1 / x2 - x1
= 5 - 8 / 1 - 3
= 3/2
The slope is 3/2x.
To find the y-intercept, plug any one of the coordinates into the equation, which is y = 3/2x + b
y = 3/2x + b
8 = 3/2(3) + b
8 = 9/2 + b
7/2 = b
The equation y = 3/2x + 7/2.

While in the blueprint, each square is 1/4...in real life, it's 4 feet per square.
Meaning, the area of each square is (4 x 4) 16 square feet.
Since there are 8 squares/tiles in the bathroom...
...multiply 8 x 16 = 128 square feet in real life.
Multiply that with the cost, and since it costs $5 per square feet:
128 x 5 = $640 (answer)For b.
Do it in similar steps.
Living room: 4 x 7 = 28 tiles
Bedroom: 4 x 5 = 20 tiles
20 + 28 = 48 tiles (in blueprint)
...multiply 48 x 16 = 768 feet square (in real life)
[Convert feet into yards...3 feet equals 1 yard]
a square yard would be 3 feet x 3 feet = 9 feet...
...divide 768 by 9
768 ÷ 9 = 85.33 square yards (rounded up)
Multiply that with the cost, and since it costs $18 per square feet:
85.53 x 18 = $1535.94 (answer)
