A culture of 1.75×1018 bacteria is in petri dish A. A culture of 6.25×1015 bacteria is in petri dish B. How many times greater is the number of bacteria in petri dish A than petri dish B
Petri dish A has 280 times more bacteria than petri dish B.
To determine how many times greater the number of bacteria in petri dish A is compared to petri dish B, we use division.
The number of bacteria in petri dish A is [tex]1.75*10^{18[/tex].The number of bacteria in petri dish B is [tex]6.25*10^{15.[/tex]We divide the number of bacteria in dish A by the number of bacteria in dish B: [tex](1.75*10^{18}) / (6.25*10^{15})[/tex].Since division of exponents with the same base involves subtracting the exponents, we have: [tex]1.75 / 6.25 * 10^{(18-15)} = 0.28 * {10^3.[/tex]Converting 0.28 into a coefficient with a single digit gives us [tex]2.8 * 10^2.[/tex]Thus, the number of bacteria in petri dish A is 280 times greater than in petri dish B.The line segment is rotated 270 degrees counterclockwise about the origin to form A'B'.

how would you simplify 9v-12v
Solve the inequality for b
10 ≥ - 2/3 (9+12B)
Final answer:
To solve the inequality 10 ≥ - 2/3 (9+12B) for b, first eliminate the fraction by multiplying both sides by -3/2, then isolate b, resulting in b ≥ -2.
Explanation:
The student has asked to solve the inequality for b: 10 ≥ - 2/3 (9+12B). To do this, follow these steps:
Multiply both sides of the inequality by the reciprocal of -2/3, which is -3/2, to get rid of the fraction. This step is crucial for simplifying the inequality.
The inequality becomes: -15 ≤ 9 + 12B.
Subtract 9 from both sides to isolate the term with b on one side: -24 ≤ 12B.
Divide both sides by 12 to solve for b: b ≥ -2.
Therefore, the solution to the inequality 10 ≥ - 2/3 (9+12B) is b ≥ -2.
A crew ship has 148 rooms with fifty on each of the two upper decks and the rest on the two lower decks.An upper deck room cost $1,000 and the lower deck room costs $900. Use the four-step plan to find the greatest possible room sales on one trip.
Final answer:
To find the greatest possible room sales on the cruise ship, multiply the number of rooms on each deck by their respective prices and add the totals, resulting in a maximum possible sale of $143,200 for one trip.
Explanation:
The question involves finding the greatest possible room sales on a cruise ship during one trip. There are a total of 148 rooms, with fifty rooms on each of the two upper decks, totaling 100 upper deck rooms. The remaining 48 rooms are therefore on the two lower decks. Since an upper deck room costs $1,000 and a lower deck room costs $900, the greatest possible room sales can be calculated by assuming all rooms are occupied during a trip.
The total sales from the upper deck rooms would be 100 rooms × $1,000, which equals $100,000. The sales from the lower deck rooms would be 48 rooms × $900, which equals $43,200. Therefore, the greatest possible room sales on one trip would be the sum of the upper and lower deck sales:
Adding these together yields a total of $100,000 + $43,200 = $143,200 for the greatest possible room sales on one trip.

Find the three consecutive odd integers whose sum is 36.
Answer: No solution
Step-by-step explanation: We can start this problem in the usual way by setting up our three consecutive odd integers as followed.
X ⇒ first integer
X + 2 ⇒ second integer
X + 4 ⇒ third integer
X + (X + 2) + (X + 4) = 36
3x + 6 = 36
-6 -6
3x = 30
÷3 ÷3
X = 10
Notice however that 10 is an even number and in the original problem, we are asked to find odd integers. Even though we can work this problem all the way through, we say that this answer doesn't make sense so we say there is no solution.

Problem:
On a trip to the lake, Kerrie and Shelly rode their bicycles four more than three times as many miles in the afternoon as they rode in the morning. If the entire trip is 112 miles, how far did they ride in the morning and how far in the afternoon?
Please SHOW ALL OF YOUR WORK!
Answer:
The answer is 27 miles in the morning and 85 miles in the afternoon.
Step-by-step explanation:
So first you have to set up an equation.
X represents: the number of miles they rode in the morning.
3X + 4 represents: 4 more than 3 times this many in the afternoon
3X+4 + X = 112 represents: adding the morning miles and the afternoon miles together to get the total trip of 112 miles
Your equation to solve 3X+4+X =112
Now you can solve the equation
3X+4+X =112
Combine like terms (x's)
3X + X = 4X
4X+4=112
Subtract 4 from each side:
4X+ 4 - 4= 112-4
4-4 = 0 and 112-4 = 108
4X = 108
Divide both sides by 4
4X/4 = 108/4
4/4 = 1X and 104/4 = 27
X = 27
Remember X represents the number of miles they rode in the morning, so they rode 27 miles in the morning.
Remember 3X+4 represents the number of miles they rode in the afternoon.
3X+4 =
3(27)+4 =
81+4 =
85 miles.
That means in the afternoon, they rode 85 Miles

Emily can ride her scooter 18 miles in 50 minutes at same rate how far she ride in 2 hrs
Emily's scooter riding speed is 0.36 miles per minute. Multiplying this rate by 120, the number of minutes in 2 hours, we find that she would be able to travel a distance of 43.2 miles in 2 hours.
Explanation:To answer your question, we first need to find what Emily's speed is. That's how fast she's going. We know that Emily can ride her scooter 18 miles in 50 minutes. So, her speed is 18 miles/50 minutes. When we calculate this, it comes out to be 0.36 miles per minute.
The problem wants us to determine how far Emily can ride in 2 hours if she continues at this same speed. Since there are 120 minutes in 2 hours, we have to multiply her rate by 120.
Doing the multiplication: 0.36 miles/minute * 120 minutes = 43.2 miles. So, Emily could travel 43.2 miles in 2 hours at the same rate.

A nutrition label indicates that one serving of Apple crisp oatmeal has 2.5 grams of fat. How many grams of fat are there in 3.75 servings? Justify your answer
To find the total grams of fat in 3.75 servings of Apple crisp oatmeal, multiply the fat per serving (2.5 grams) by the number of servings, resulting in 9.375 grams of fat.
To calculate the number of grams of fat in 3.75 servings of Apple crisp oatmeal, we can multiply the amount of fat in one serving by the number of servings. Given that one serving contains 2.5 grams of fat, we would perform the following calculation:
2.5 grams of fat/serving times 3.75 servings = 9.375 grams of fat
Therefore, there are 9.375 grams of fat in 3.75 servings of Apple crisp oatmeal. The nutrition label helps us understand the nutritional content of food, like the breakdown of macronutrients such as fats, carbohydrates, and proteins, as well as the caloric content of these macronutrients.
