Step-by-step explanation:
Area of the surface of the cuboidal box to be painted = surface area of the cuboidal box - area of the base
✔️Surface area of the cuboidal box = 2(L*W + W*H + L*H)
L = 6 cm
W = 4 cm
H = 2.5 cm
Surface area of the cuboidal box = 2(6*4 + 4*2.5 + 6*2.5) = 2(24 + 10 + 15) = 2(49)
Surface area of cuboidal box = 98 cm²
✔️Area of base = L*W
= 6*4 = 24 cm²
Area of the cuboidal box to be painted = 98 - 24 = 74 cm²
✔️Cost of painting 74 cm² at Rs. 4.50 per cm² = 74 × 4.50 = Rs. 333

A cylindrical container contains some sand. If the diameter of the container is 10 inches and its height is 3 inches, about how much sand fits inside the container?
Answer:
251.33in²
Step-by-step explanation:
A cylindrical container contains some sand. If the diameter of the container is 10 inches and its height is 3 inches, about how much sand fits inside the container?
We solve the above question using the formula for Total surface area of a cylinder.
TSA = 2πr (h + r) Square units.
Where
h = Height of the cylinder
r = Radius of the cylinder
Diameter of the container is 10 inches
Hence, radius = Diameter/2 = 10/2 = 5 inches
Height is 3 inches.
Hence, Total surface area =
2 × π × 5 (5 + 3)
= 10π × (8)
= 251.32741229 in²
Approximately = 251.33 in²
Therefore, the amount of sand that can fit into the cylinder = 251.33 in²

If a series RC circuit is operating at 100 VAC and has an impedance of 52.5 ohms, what is the circuit current
Answer:
1.9 Amps
Step-by-step explanation:
In an RC circuit, the relationship between the current I in amps, the impedance Z in ohms and the voltage V in volts may be stated as
V = IZ
As such, given that z = 52.5 ohms and V = 100 Volts, the current in the circuit I may be computed as
100 = I * 52.5
Divide both sides by 52.5
I = 100/52.5
= 1.9 Amps

4. Leroy creates customized engraved
birthday cards for his schoolmates.
He charges them $0.75 per card, plus a
dollar for each engraved letter in
the recipient's name. The equation
C=0.75 + l describes the cost of a card
in dollars, c, that has a certain number of
letters in the name, l.
Number of Letters
in Name
Cost of Card
(dollars)
3.75
5.75
6.75
8.75
If you have $10.75 to spend on a card,
how many letters can be in the recipient's
name?
Answer:
10
Step-by-step explanation:
C = 0.75 + L
For L = 3 ; Cost, C = 3.75
3.75 = 0.75 + 3L
3.75 - 0.75 = 3L
3 = 3L
L = 3/3
L = $1
C = 0.75 + 1L
If amount spent is $10.75; C = 10.75
10.75 = 0.75 + L
10.75 - 0.75 = L
10 = L
Number of letters = 10
Which expression is equivalent to 6x+8?
A 2(3x-4)
B 2(3x+4)
C 2(4x+6)
D 2(3x+8)
Answer:
B
Step-by-step explanation:
=> 6x+8
We see that 6 and 8 have following factors:

294÷3=98
Answer:
98 x 3 = 294 or 3 x 98 = 294
Step-by-step explanation:
Since 294 divided by 3 is 98, that means 294 is 3 times 98. So, we can say:
3 x 98 = 294
We can also say that 98 x 3 = 294 since it doesn't matter in which order you multiply.

–6w + (–8) + 1 + (–7w)
A. –w – 7
B. –13w – 7
C. w + 9
D. 13w + 9
Answer:
-13w-7
Step-by-step explanation:
-6w+(-8)+1+(-7w)
-6w-8+1-7w
-6w-7w-8+1
-13w-8+1
-13w-7
Answer:
B. -13w-7
Step-by-step explanation:
First, let's simplify the problem by grouping the like terms together: (-6w), (-7w), and (-8), (1).
Second, now that you know the like terms solve them each individually:
(-6w) + (-7w) = -13w
(-8) + 1 = -7
So your answer is -13w minus -7

Ben's living room is a rectangular measuring 12 yards x 204" by how many feet does the length of the room exceed the with the length of the room exceeds the width by blank feet
Answer:
The length of the room exceeds the width by 19 feet
Step-by-step explanation:
From the question, the room measures 12 yards x 204", that 12 yards x 204 inches. To determine by how many feet the length of the room exceeds the width, we will first convert both units of measurement ( yards and inches) to feet.
To convert 12 yards to feet,
1 yard = 3 feet
∴ 12 yards will be 3 × 12 feet = 36 feet
To convert 204" to feet
12" = 1 foot
∴ 204" will be 204/12 feet = 17 feet
Hence, the room measures 36 feet × 17 feet
That is, Length of the room = 36 feet
and width of the room = 17 feet
Now, to determine by how many feet the length of the room exceeds the width, we will deduct the width of the room from the length of the room, that is,
36 feet - 17 feet = 19 feet
Hence, the length of the room exceeds the width by 19 feet.
