Determine the result of the expression: What is ∣−10−(∣4∣+1)∣?
- A.
15
- B.
-15
- C.
7
- D.
5
Correct Answer
A. 15Explanation
Let's break down the expression step by step:
Absolute Value of 4: The absolute value of 4 is simply 4 because the absolute value of a positive number is the number itself.
Absolute Value of -10: The absolute value of -10 is 10 because it's the positive distance from zero to -10 on the number line.
Now, we have the expression: | -10 - (|4| + 1) |
Inside the innermost parentheses, we calculate |4| + 1, which is 4 + 1 = 5.
Then, we have -10 - 5 inside the outer parentheses, which is -15.
Finally, we take the absolute value of -15, which is 15.

- B.
T/7 = 2 + (-4).
- C.
T/7 + 2 = -4.
- D.
Both "a" and "b."
Correct Answer
C. T/7 + 2 = -4.Explanation
To translate the given statement "The quotient of a number t and 7, plus 2, is -4," we need to find the correct algebraic expression that matches this description.
The statement can be broken down as follows:
"The quotient of a number 𝑡t and 7" means t/7
"plus 2" means we add 2 to the quotient.
"is -4" means the expression equals -4.
Putting it all together, we get:
t/7+2=-4Rate this question:

What is the decimal representation of 1/4?
- A.
0.1.
- B.
0.01.
- C.
0.25.
- D.
0.5
Correct Answer
C. 0.25.Explanation
A fraction can be converted into a decimal by dividing the numerator by the denominator. In this case, divide 1 (the numerator) by 4 (the denominator): 1 ÷ 4 = 0.25. This means that 1/4 is equal to 0.25 as a decimal. Decimals represent parts of a whole, and 0.25 corresponds to one-quarter of 1. This value is often used in daily measurements, such as money or weights, making it an important concept in arithmetic. Thus, the decimal representation of 1/4 is accurately written as 0.25.Rate this question:

How can 0.4 be represented as a fraction?
- A.
7/10.
- B.
2/5.
- C.
0.4/4
- D.
1/2
Correct Answer
B. 2/5.Explanation
To write 0.40.4 as a fraction and simplify it:
Write 0.4 as a fraction:
0.4=4/10
Simplify the fraction by finding the greatest common divisor (GCD) of 4 and 10, which is 2:
4÷2/10÷2=2/5
So, 0.4 as a simplified fraction is 2/5Rate this question:

How can 0.55555... be represented as a fraction?
- A.
5/9
- B.
5/10
- C.
1/2
- D.
1/3
Correct Answer
A. 5/9Explanation
To express the repeating decimal 0.55555... as a fraction and simplify it, we can set up the following equation:
x = 0.55555...
Now, we'll subtract this repeating decimal from 10x, which should eliminate the repeating part:
10x - x = 5.55555... - 0.55555...
9x = 5
Now, divide both sides by 9 to solve for x:
x = 5/9
So, the repeating decimal 0.55555... is equal to the fraction 5/9.Rate this question:

Which is greater?: -3/7 or -0.375
- A.
-3/7 < -0.375
- B.
-3/7 > -0.375
- C.
-3/7 = -0.375
Correct Answer
A. -3/7 < -0.375Explanation
To determine which is greater, −3/7 or -0.375 we need to compare the two values. We can convert -3/7 to a decimal for an easier comparison.
Convert -3/7 to a decimal
-3/7 ≈ 0.4286
Compare the two decimals:
−0.4286 (approximate value of −3/7)
−0.375
Since −0.4286 is less than −0.375, −0.375 is greater.
Therefore, −0.375 is greater than −3/7Rate this question:
