Answer:

Step-by-step explanation:

The expression "twice as much lemonade" indicates that if Mark sold 2 gallons and Regan sold double that amount, Regan would have 2 * 2, equating to 4 gallons, right? The same principle applies to "2/3 as much." Since 2/3 is less than 1, multiplying a quantity by 2/3 results in a value smaller than the original quantity.

If Mark sold 2 7/8 gallons while Regan sold 2/3 of that amount, then Regan's total is:

2\frac{7}{8}*\frac{2}{3}

To simplify calculations, I advise my algebra students to convert the mixed number into an improper fraction before multiplication:

\frac{23}{8}*\frac{2}{3}=\frac{46}{24}=\frac{23}{12}=1\frac{11}{12}

Svet_ta [12734]
The correct answer is A. According to the question's details, we're provided with key statistics on zucchini weights, which suggest that the average turns out to be typically 0.8 pounds, while the standard deviation is noted as 0.25 pounds. The probability of a randomly selected zucchini weighing between 0.55 pounds and 1.3 pounds can be mathematically expressed. Observing the provided normal distribution options, option A aligns with our specified weight range.

Laurence, the stadium manager, spends $22,000 on a broadcast TV ad, $30,000 on a cable TV ad, and $6,000 on a radio ad. What per
Zina [12379]

38 % of the total budget goes to advertising on broadcast TV

Solution:

Based on the details,

Expenditure for broadcast TV advertising = $ 22, 000

Expenditure for cable TV advertising = $ 30, 000

Expenditure for radio advertising = $ 6000

Need to determine: the proportion of broadcast TV advertising

Total expenditure = $ 22, 000 + $ 30, 000 + $ 6000

Total expenditure = $ 58000

proportion of broadcast TV advertising = \frac{\text{ amount spend on broadcast tv}}{\text{ total amount}} \times 100

\rightarrow \frac{22000}{58000} \times 100\\\\\rightarrow 0.3793 \times 100 = 37.93 \approx 38

Hence 38 % of the total budget is allocated to broadcast TV advertising

A periscope is 5 feet above the surface of the ocean. Through it can be seen a ship that rises to 50 feet above the water. To th
PIT_PIT [12445]

The maximum distance visible on Earth is calculated using the formula d=\sqrt{8,000h_1} + \sqrt{8,000h_2}

h_1= your initial height and h_2= your secondary height

In this case, h_1=5 represents the height of the periscope and h_2=50 denotes the height of the ship, leading us to a distance of 832.45553203368 feet. However, rounding to the nearest mile yields the answer as 11^a^0

If there are any discrepancies, please inform me and I will recalculate!

 x = 27 + 3 √ 129/ 4, 27 − 3 √ 129/ 4

Please note: the entire equation mentioned is divided by 4, not only the last term. 

 x approximates to 15.26836251, − 1.76836251

That concludes my response. I hope this is helpful. You will still need to work on finding y and z, which can be quite challenging:)
