Answer:
1160 cm^2
Step-by-step explanation:
Surface area=2(lw)+2(hl)+2(hw)
So, surface area=2(15x20)+2(8x15)+2(8x20)
=2(300)+2(120)+2(160)
=600+240+320
surface area=1160 cm^2.
The surface area of the cuboid is 1160 cm²
What is the surface area of cuboid?
The total surface area of the cuboid is given by the formula
Surface Area = 2 ( LH + LW + HW )
where ,
Length of the cuboid = L
Width of the cuboid = W
Height of the cuboid = H
Given data ,
Length of the cuboid L = 15 cm
Width of the cuboid W = 20 cm
Height of the cuboid H = 8 cm
Surface Area of the cuboid = 2 ( LH + LW + HW )
Substituting the values of L , H and W in the equation , we get
Surface Area of the cuboid = 2 ( ( 15 x 8 ) + ( 15 x 20 ) + ( 20 x 8 ) )
So ,
Total surface area of the cuboid = 2 ( 120 + 300 + 160 ) cm²
= 2 ( 580 ) cm²
= 1160 cm²
Hence , the Total surface area of the cuboid is 1160 cm²

Rosie bought a car for £4000
3 years later, she sells it for £1400
What is the percentage loss that Rosie has made?
Answer:
65%
Step-by-step explanation:
Given data
Cost price= £4000
Selling price= £1400
% loss= cost price-selling price/cost*100
% loss= 4000-1400/4000*100
% loss= 2600/4000*100
% loss= 0.65*100
% loss= 65%
Hence the %loss is 65%

Find the area of the parallelogram below.
The formula for finding the area of a parallelogram is Base x height
A = Bh
In this case the base (the longest side) is 8 cm and the height (distance between the obtuse angle and the base) is 5 cm
A = 8 * 5
A = 40 cm²
Hope this helps!
~Just a girl in love with Shawn Mendes
Answer: 40cm²
The formula is Base × Height. We can find the area if we multiply the Base and Height.
A = Bh
As for that, the Base is the upper length, which is 8 and the height is the obtuse angle inside the parallelogram, which is 5.
Since we got our lengths, we can solve.
Remember how I said the formula is A = Bh. (Area = Base × Height)
So, we can multiply 8 by 5 to get the area.
8 times 5 will equal 40.
Hence, 40cm² is the answer.

How much greater is the perimeter of a triangular field with sides that measure 92 yards, 83 yards, and 99 yards than the perimeter of a triangular field with sides that measure 61 yards, 38 yards, and 83 yards?
Answer:
92 yards
Step-by-step explanation:
Perimeter of a triangle = a + b + c
Field 1 :
Perimeter = (92 + 83 + 99) yards = 274 yards
Field 2:
Perimeter = (61 + 38 + 83) yards = 182 yards
Perimeter difference :
Field 1 - Field 2
(274 - 182) yards
= 92 yards

what's bigger 35% or 2/5
Answer:
2/5
Step-by-step explanation:
cause if you put it in a percent it would be 40% so bigger than 35%
Answer:
2/5 is bigger than 35%
Step-by-step explanation:
2/5 can be written as 4/10, which is equivalent to 40/100, or the percentage 40%. And since 40% is bigger than 35%, 2/5 is bigger than 35% :)
True or False?
k = 2 is a solution to the inequality 8k+ 4 > 18.
Answer:
True
Step-by-step explanation:
If k = 2, then we plug in 2 for every instance there is a k. So...
8k + 4 > 18
Will turn into...
8(2) + 4 > 18
Then solve using PEMDAS (or whatever you were taught. Parenthesis, Exponent, Multiplication/Division, Addition/Subtraction.)
16 + 4 > 18
20 > 18
Since 20 is greater than 18, 2 can be a solution for this inequality.
