Mathematics
1 answer:
Butoxors [25]2 years ago
4 0

Correct option is B. A discovery in New Jersey actually contributed to the

early economic development of America and, in 1714, a worker uncovered a green rock containing copper.

Here, the use of conjunction 'and' is incorrect as it creates a kind of distortion which seems as if we are talking about two different things: rather then linking the two parts of the sentence, 'and' further disconnects it.

"When" seems better than "And". It clearly indicates the mentioned time. Thus B is the correct answer.

hammer [34]

Answer:

s = 22w

Step-by-step explanation:

We need to try this equation for all of the numbers in the table.

s = 22w

22 = 22 * 1

s = 22w

44 = 22 * 2

s = 22w

66 = 22 * 3

s = 22w

88 = 22 * 4

s = 22w

110 = 22 * 5

Triple my number add six and subtract my number twice I get my number plus three
liberstina [14]
Let the number be x.

Triple the number means 3x
add 6 means 3x + 6
subtract the number twice 3x + 6 - x - x
the result is the number plus 3 means that the result is x + 3

So, combining these into an equation, we get:
3x + 6 - x - x = x + 3

If we solve this equation for x, we will get:
x + 6 = x + 3
The x will cancel out and we will get : 6 = 3

Therefore, this is a false statement.

What is the length or area of shaded part?
Ivanshal [37]

Answer:

29.7345 square units

Step-by-step explanation:

Area of the shaded part = Area of the rectangle - Area of the quarter circle

Area of the rectangle = Length × Width = 10 × 8 = 80 square units

Area of the quarter circle = \frac{1}{4} × π × r² (r for radius) = 0.25 × π × 8² = 50.2655 square units (answer rounded up to four decimal places)

Area of the shaded part = 80 square units - 50.2655 square units = 29.7345 square units
