Find the value of x, given that 4(3x+2)=44.

Answers

Answer:

X=3

Step-by-step explanation:

=> 4(3x+2)=44

=> 12x=44 - 8 [Transpose 8 of L.H.S to R.H.S]

=> 12x= 36

=> x= (3)

If a series RC circuit is operating at 100 VAC and has an impedance of 52.5 ohms, what is the circuit current

Answers

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

-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

Answers

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.

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?

Answers

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

maths very easy class 8

Rs. 333

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

8.75

If you have $10.75 to spend on a card,

how many letters can be in the recipient's

name?

Answers

Answer:

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

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

Answers

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.
