Lucy rode her bike around the block 4 times for a total of 1 mile yesterday. Today she wants to ride her bike 3/4 of a mile. how many times will she need to ride her bike around the block
Final answer:
Lucy will need to ride around the block 3 times today to cover 3/4 of a mile, as each lap around the block is 0.25 miles long.
Explanation:
Lucy rode her bike around the block and covered a total distance of 1 mile by doing so 4 times. Each lap around the block is therefore 0.25 miles long (1 mile ÷ 4 laps = 0.25 miles per lap). To cover 3/4 of a mile, Lucy needs to complete three laps (3/4 of a mile ÷ 0.25 miles per lap = 3 laps). This is because 3/4 divided by 1/4 (which is the distance of one lap) equals 3. Hence, Lucy will need to ride around the block 3 times today to cover 3/4 of a mile.

Tamar is thinking of a number in the hundredths. Her number is greater than 0.8 and less than 0.9. The greatest digit in the number is in the hundredths place. What number is Tamar thinking of? Explain.
Answer:
Therefore, Tamar is thinking of the number 0.89.
Step-by-step explanation:
Let x be the number Tamar is thinking of.
0.8 < x < 0.9
Since the greatest digits in the hundreths is greater digit, and there's an "8" in the tenths, the number can described as:
0.88< x < 0.9
There is only a single number in the hundredths that would fit the expression above, and that is 0.89.
Therefore, Tamar is thinking of the number 0.89.
Answer:
Let the be the number Tamar is thinking of. So from the above question,
0.8 < t < 0.9
Note that the greatest digits in the hundreths is greater digit, and there's an "8" in the tenths, the number can described as:
0.88< x < 0.9
There is only a number in the hundredths that would fit and that is 0.89.
Therefore, t = 0.89.
Step-by-step explanation:
Twenty-one people in a room have an average height of 5 feet 6 inches. a 22nd person enters the room. how tall would he have to be to raise the average height by 1 inch?
To raise the average height by 1 inch, the 22nd person would have to be 88 inches tall.
Explanation:To find how tall the 22nd person would have to be in order to raise the average height by 1 inch, we can use the concept of average. Currently, there are 21 people with an average height of 5 feet 6 inches. This means that the total height of all 21 people combined is 5 feet 6 inches multiplied by 21.
If we want to raise the average height by 1 inch, we need to add a certain amount of height to the total height of all the people in the room. Let's call this additional height 'x'. So the new total height would be the previous total height plus 'x'.
Since the total number of people in the room will become 22, the new average height will be the new total height divided by 22. We can set up an equation to solve for 'x':
5 feet 6 inches multiplied by 21 plus 'x' divided by 22 equals 5 feet 6 inches plus 1 inch.
To solve this equation, we can first convert the heights to inches: 5 feet 6 inches is equivalent to 66 inches. Now we can solve the equation:
66 multiplied by 21 plus 'x' divided by 22 equals 67.
Now we can simplify and solve for 'x':
1386 plus 'x' divided by 22 equals 67.
1386 plus 'x' equals 67 multiplied by 22.
1386 plus 'x' equals 1474.
Subtracting 1386 from both sides, we get 'x' equals 1474 minus 1386, which is 88 inches. Therefore, the 22nd person would have to be 88 inches tall to raise the average height by 1 inch.

Which function has a simplified base of 4 ^3 sqrt 4?
Final answer:
The function in question involves simplifying the base 4^3 multiplied by the square root of 4. Through understanding exponent rules and square root operations, this simplifies to 128, demonstrating the importance of algebraic fundamentals.
Explanation:
Understanding the Simplified Base of 4^3 \sqrt{4}
The question asks which function has a simplified base of 4^3 \sqrt{4}. Simplifying this expression requires understanding of exponent rules and square roots. The cube of 4, or 4^3, equals 64. The square root of 4 is 2, hence \(\sqrt{4}\) simplifies to 2. Combining these, we see that 4^3 multiplied by \(\sqrt{4}\) equals 64 * 2 = 128.
To put this into perspective, we would express the original operation as 4 raised to the power of 3 and then multiplied by the square root of 4, which can also be depicted as 4^3 * 2 since \(\sqrt{4} = 2\). Thus, the simplified base is not a direct function but rather an arithmetic operation resulting in 128.
It's crucial to note that while operations like these involve basic principles of exponents and roots, each step must be carefully followed to ensure accuracy. The concept behind these operations is grounded in the mathematical principles of handling integers, powers, and roots, highlighting the importance of solid fundamentals in algebra.

a.m. [2] as a general rule, the company limits the number of conference calls to three per hour. [3] in the future, we should be more careful about scheduling calls. which sentence contains a flabby expression
Final answer:
The flabby expression is found in the sentence 'In the future, we should be more careful about scheduling calls,' which can be more concisely stated as 'In the future, we should schedule calls more carefully.'
Explanation:
The sentence that contains a flabby expression is: "In the future, we should be more careful about scheduling calls."
Flabby expressions are phrases or sentences that are wordy and can be expressed more concisely without losing their meaning. The sentence could be more directly stated as "In the future, we should schedule calls more carefully." By removing unnecessary words, the sentence becomes clearer and more to the point. Flabby expressions are usually considered poor writing style because they can make sentences needlessly long and obscure the main point.
According to the Rational Root Theorem, the following are potential roots of f(x) = 60x2 – 57x – 18. Which is an actual root of f(x)? , 3 6, -1/4,-6/5
Answer:
the answer is -1/4
Step-by-step explanation:
Final answer:
The actual root of the polynomial f(x) = 60x²– 57x – 18 among the given options is -6/5.
Explanation:
According to the Rational Root Theorem, possible roots of the polynomial equation f(x) = 60x² − 57x − 18 are the factors of the constant term (−18) divided by the factors of the leading coefficient (60). The roots could be ±1/60, ±1/30, ±1/20, ±1/15, ±1/12, ±1/10, ±1/6, ±1/5, ±1/4, ±1/3, ±1/2, ±1, ±2/5, ±3/5, ±6/5, ±9/5, ±18/5, ±2, ±3, ±6, ±9, ±18.
To determine which of the given options are actual roots of the polynomial, we substitute each value into the polynomial and check if it returns a value of zero:
Substituting x = 3 into f(x) gives 60(3)² − 57(3) − 18 = 540 − 171 − 18 = 351, which is not zero.
Substituting x = 6 into f(x) gives 60(6)² − 57(6) − 18 = 2160 − 342 − 18 = 1800, which is not zero.
Substituting x = −1/4 into f(x) gives 60(−1/4)² − 57(−1/4) − 18 = 15 − −14.25 − 18 = 11.25, which is not zero.
Substituting x = −6/5 into f(x) gives 60(−6/5)² − 57(−6/5) − 18 = 86.4 − −68.4 − 18 = 0, which is zero. Therefore, −6/5 is an actual root of the equation.
Thus, the actual root among the given options is −6/5.

The factorization of x2 + 3x – 4 is modeled with algebra tiles.What are the factors of x2 + 3x – 4?
The factors of x^2 + 3x – 4 are (x + 4) and (x - 1), found by determining the factors of -4 that add up to 3.
Explanation:The factors of x2 + 3x – 4 can be found using the method of factoring quadratics. To factor this quadratic expression, we look for two numbers that multiply to give the constant term (-4) and add to give the coefficient of the middle term (3). Those numbers are 4 and -1, as 4 × -1 = -4 and 4 + (-1) = 3. Therefore, the expression can be factored into (x + 4)(x - 1).
Visualizing with algebra tiles or drawing on the concepts of geometric representation of polynomials, we can understand that this factoring corresponds to breaking down the area of a rectangle (represented by x2 + 3x – 4) into two smaller rectangles whose dimensions give the factors (x + 4) and (x - 1).
