Answer:
Surface area means all 6 sides
TOP side= 2 multiplied by 5
Bottom = 2 multiplied by 5
Right face = 2 multiplied by 8.1
Left face = 2 multiplied by 8.1
Back side = 5 multiplied by 8.1
front side = 5 multiplied by 8.1
10+10+16.2+16.2+40.5+40.5 = 133.4 cm ^2
Answer:
133.4 cm²
Step-by-step explanation:
The opposite faces of the cuboid are congruent, thus
front/ back = 2(8.1 × 5) = 2 × 40.5 = 81 cm²
top/ bottom = 2(5 × 2) = 2 × 10 = 20 cm²
sides = 2(8.1 × 2) = 2 × 16.2 =32.4 cm²
Thus
Surface area = 81 + 20 + 32.4 = 133.4 cm²

Answers
Answer:
a) 2nd container is more efficient and contains the elements for a container.
b) The cylinder has a........A)Smaller surface area B)bigger C)equal
And will cost.....A)Less to produce B)more C)The same
Step-by-step explanation:
a) The 2nd container has these elements:
Width 20.5cm
Length 6.5cm
side 3.25cm
So, the volume in cubic cm is 20.5 x 6.5 x 3.25 = 433cm3.
This container can hold the 300cm3 of juice.
b) A cylinder is a geometric solid common in everyday life. Examples of a cylinder are soup cans, food tins, drink cans, candles, toilet paper rolls, cups, aerosol cans, flower vases, test tubes, fire extinguishers, plant containers, salt shakers and pencil holders. The two ends are called bases, and are usually circular. Though, they can take other shapes. When a cylinder is unrolled and flattened out, the side is actually a rectangle.
The surface area of a cylinder is the surface area of each end plus the surface area of the side. The mathematical formula is 2π * r2, where π is the pie and r is the radius of the end and r2 is r squared..

How many total ounces of perfume are in the result
in each trial (each row?
Answers
Answer:
10 oz
Step-by-step explanation:
edge
The total ounces of perfume in trials 1, 2, and 3 are 7.8 oz, 7.3 oz, and 7.65 oz.
Given to us,
For Trial 1,
A = 2 oz
B = 4 oz
C = 4 oz
Percentage of rose oil = 22%
weight of trail 1 = A+ B+ C = 2+ 4+ 4 = 10 oz.
Weight of rose oil in trial 1 = weight of trail 1 x Percentage of rose oil in 1
= 10 oz x 22% = 2.2 oz
total ounces of perfume in trial 1
= weight of trail - Weight of rose oil in trial 1
= 10 - 2.2 = 7.8 oz
For Trial 2,
A = 4 oz
B = 2 oz
C = 4 oz
Percentage of rose oil = 27%
Total weight of trail 2 = A+ B+ C = 2+ 4+ 4 = 10 oz.
Weight of rose oil in trial2 = weight of trail 2 x Percentage of rose oil in 2
= 10 oz x 27% = 2.7 oz
total ounces of perfume in trial 2
= weight of trial 2 - Weight of rose oil in trial 2
= 10 - 2.7 = 7.3 oz
For Trial 3,
A = 1 oz
B = 7 oz
C = 2 oz
Percentage of rose oil = 23.50%
Total weight of trail 3 = A+ B+ C = 2+ 4+ 4 = 10 oz.
Weight of rose oil in trial 3= weight of trail 3 x Percentage of rose oil in 3
= 10 oz x 23.50% = 2.350 oz
total ounces of perfume in trial 3
= weight of trail - Weight of rose oil in trial 3
= 10 - 2.2 = 7.8 oz
Hence, The total ounces of perfume in trials 1, 2, and 3 are 7.8 oz, 7.3 oz, and 7.65 oz.

Find the missing length, when you know the perimeter. 9m + 9m + ? + ? = 42m
Answers
Answer:
MISSING LENGTH IS 12 M
Step-by-step explanation:
9+9+ ? + ? = 42m
18+ X + X = 42m
2X=42-18
2X=24
X=12
Answer:
The missing length is 12 meters.
Step-by-step explanation:
9+9+x+x=42
Subtract 9 from both sides
9+x+x=33
Subtract 9 from both sides
x+x=24
2x=24
Divide both sides by 2
x=12

The population of a town can be modeled using the formula P=20,000e^0.02t , where t is the number of years after 2012 and P is the town's population. Which of the following equations can be used to find the number of years after 2012 that the population will double to 40,000?
Answers
Answer:
t= ((ln*2)/(0.02)
Step-by-step explanation:
plug 40000 in for P and solve for t
40000=20000e^0.02t
-divide both sides by 20000: 2=e^0.02t
-in order to cancel out e, multiply both sides by the natural log (ln)
ln(2)=0.02t
-divide 0.02 on both sides to get t by its self
Answer: t = ((ln(2)/(0.02))
1) Tanya is buying edging for a triangular flower garden she plans to build in her backyard. If the lengths of the three pieces of edging that she purchases are 13 feet, 10 feet, and 7 feet, will the flower garden be in the shape of a right triangle ?
Answers
Answer:
The Flower Garden is not in the shape of a right Δ
Step-by-step explanation:
~ To prove that this garden is in the shape of a right triangle, it can be done so through contradiction ~
Pythagorean Theorem is applied to a right triangle, so we can say that the two legs are 10 and 7 feet, the hypotenuse being 13, knowing it is the longest side;
a^2 + b^2 = c^2,
10^2 + 7^2 = 13^2,
100 + 49 = 169,
149 ≠ 169,
So the Flower Garden will not be in the shape of a right Δ

Write an equation of the line in slope-intercept form. The points are (0,1) and (2,-5)
Answers
Your answer is y = -3x + 1
To find the equation of the line we need both the slope and where it intercepts the y-axis. We are given where it intercepts the y-axis because they tell us it goes through the point (0, 1) and this is a point where x = 0, so it must be on the y-axis.
The equation for finding the slope of a line given two points is [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] where [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] are points on the line. Using this, we can substitute in the points we're given and get:
(-5 - 1)/(2 - 0) = -6/2 = -3
Therefore our slope is -3 and our intercept is 1, so the final answer is y = -3x + 1
