Jacob wants to use an elevator to carry identical packages having the same weight. Each package weighs 3 pounds and Jacob weighs 99 pounds. If the elevator can carry a maximum of 300 pounds at a time, which inequality shows the maximum number of packages, n, that Jacob can carry with himself in the elevator if he is the only passenger?

n ≤ 67
n ≥ 67
n ≤ 198
n ≥ 198

Okay so fiquring out 1/2 of 1/4 is simple got to the third diagram since it has been cut to match the 1/2.  1/3 of 3/8 would be the first diagram since the squares have been sliced in half.

[tex]\dfrac{4}{9}-\left|\dfrac{5}{18}\right|=\dfrac{4}{9}-\dfrac{5}{18}=\dfrac{8}{18}-\dfrac{5}{18}=\dfrac{3}{18}=\dfrac{1}{6}[/tex]

Well, the opposite of an exponent is a square root. However, in this case, it is to the power of 3. So in order to find p, you must do the cube root on both sides in order to get your answer:

[tex]p^3=3[/tex]

[tex]\sqrt[3]{p^3} =\sqrt[3]{8}[/tex]

[tex]p=2[/tex]

11

11.06

11.56

11.6

is what you are looking for

The order would go 11; 11:06; 11.56; 11.6

The answer you are looking for would be 63.

63 is greater than 60, but less than 70, and the tens place (6) is double the ones place (3). Thus meaning 63 is the answer.

You can use the substitution method to solve.

Answer:

The second gear will complete 75 complete revolutions

Step-by-step explanation:

- There are two connected gears

- One has 60 teeth and the other has 40 teeth

- The two gears have different revolutions depends on the number of

  their teethes

- They do the same job

- The relation between them is

   [tex]n_{1}*c_{1}=n_{2}*c_{2}[/tex], where n is the number of the complete

   revolutions and c is the number of the teeth

- The gear which has less teethes makes more complete revolutions

∵ [tex]n_{1}[/tex] = 50

∵ [tex]c_{1}[/tex] = 60

∵ [tex]c_{2}[/tex] = 40

- Substitute these values in the rule below

∵ [tex]n_{1}[/tex] × [tex]c_{1}[/tex] = [tex]n_{2}[/tex] × [tex]c_{2}[/tex]

∴ 50 × 60 = [tex]n_{2}[/tex] × 40

∴ 3000 = 40 [tex]n_{2}[/tex]

- Divide both sides by 40

∴ [tex]n_{2}[/tex] = 75 complete revolutions

The second gear will complete 75 complete revolutions

Step 1. Factor out the common term 2

n - 2 = 2(5n + 2)/2

Step 2. Cancel 2

n - 2 = 5n + 2

Step 3. Subtract n from both sides

-2 = 5n + 2 - n

Step 4. Simplify 5n + 2 - n to 4n + 2

-2 = 4n + 2

Step 5. Subtract 2 from both sides

-2 - 2 = 4n

Step 6. Simplify -2 - 2 to -4

-4 = 4n

Step 7. Divide both sides by 4

-1 = n

Step 8. Switch sides

n = -1

To find the value of n, rearrange the equation and simplify to solve for n.

To find the value of n, we need to solve the given equation. First, distribute the 2 on the right side:

n - 2 = 10n + 4

Next, subtract 10n from both sides:

n - 10n - 2 = 4

Combine like terms:

-9n - 2 = 4

Then, add 2 to both sides:

-9n = 6

Finally, divide both sides by -9 to solve for n:

n = -6/9 which simplifies to n = -2/3.

Answer:

5000 square feet of lawn would provide the daily supplies of oxygen for 8 organisms.

Explanation:

 The daily supply of oxygen for a particular multi cellular organism is provided by 625 square feet of lawn

Total area of lawn provided = 5,000 square feet

Number of organism for which provided lawn area supplies oxygen = Total area of lawn provided/ Daily requirement of lawn area for 1 organism.

Number of organism for which provided lawn area supplies oxygen = 5000/625 = 8 organisms.

So 5000 square feet of lawn would provide the daily supplies of oxygen for 8 organisms.

A total of 5,000 square feet of lawn would provide the daily supplies of oxygen for 8 organisms based on the ratio given.

The question can be solved using the concept of ratios. The ratio of lawn to organisms is 625 square feet to 1 multicellular organism. So, if we have 5,000 square feet lawn area, we can find how many organisms it can support by setting up a proportion and solving for the unknown number of organisms.

Let's denote the unknown number of organisms as X. The proportion would then be: 625/1 = 5000/X.

To solve this equation for X, we can cross-multiply and divide. So, X = 5000 / 625 = 8 multicellular organisms.

a 1.25L Coca Cola that cost $1.29

Unit rate means we need to find the rate of 1 liter of Coca Cola

Let the speed of the boat in still water = X

The current is 3 mph, so the speed of the boat going upstream would be x-3

Speed of the boat going down stream would be x +3

The trip upstream is 26 / x-3

The trip downstream is 38 / x+3

Set them to equal and solve for x:

26/x-3 = 38/x+3

Multiply both sides by (x+3)(x-3):

38(x-3) = 26(x+3)

Simplify:

38x - 114 = 26x+78

Subtract 26x from each side:

12x -114 = 78

Add 114 to each side:

12x = 192

Divide both sides by 12:

x = 192 / 12

x = 16

The speed is 16 miles per hour.

To determine the boat's speed in still water, an equation is set up that relates the upstream and downstream times, given that the current influences the boat's effective speed by 3 mph. Solving this equation yields a speed of 16 mph for the boat in still water.

To find the speed of the boat in still water, we need to account for the effect of the current on the boat's speed when going up and down the river. Let the speed of the boat in still water be v mph.

When the boat is going upstream (against the current), its effective speed is (v - 3) mph because the current slows the boat down by 3 mph. When the boat is going downstream (with the current), its effective speed is (v + 3) mph because the current speeds the boat up by 3 mph.

Since the boat covers 26 miles upstream and 38 miles downstream in the same time, we can set the time equal for both scenarios:

Time = Distance / Speed

By equating the two times, we get:

26 / (v - 3) = 38 / (v + 3)

To solve for v, cross-multiply and simplify:

26(v + 3) = 38(v - 3)

26v + 78 = 38v - 114

12v = 192

v = 192 / 12

v = 16 mph

Therefore, the speed of the boat in still water is 16 mph.

Subtract 3n from each side

(3n)-3n+6 = 5n-3n-4

The answer you are looking for is 2/3.

When adding or subtracting fractions, they must have the same denominator. To make 1/6 and 1/2 have the same denominator, you must multiply 1/2 by 3/3 straight across. This gives you 3/6 which you can now add 1/6 to to get 4/6. 4/6 can be simplified down to 2/3 by dividing by 2/2. Thus making 2/3 the answer.

To add one sixth and one half, convert them to have the same denominator, resulting in 1/6 plus 3/6 (or 4/6), which simplifies to two thirds.

When adding fractions such as one sixth and one half, it's essential to have a common denominator. To find a common denominator for 1/6 and 1/2, we need to think about the multiples of both 6 and 2. The smallest common multiple is 6, so we convert 1/2 into a fraction that has 6 as the denominator. The fraction 1/2 is equivalent to 3/6 since 2 multiplied by 3 equals 6. Now we can add the fractions:

Therefore, one sixth plus one half is equal to two thirds.

The probability that neither of them suffer from myopia can be calculated by finding the probability that one individual does not suffer from myopia and then multiplying that probability by the probability that the second individual also does not suffer from myopia.

Explanation:

The probability that neither of them suffer from myopia can be calculated by finding the probability that one individual does not suffer from myopia and then multiplying that probability by the probability that the second individual also does not suffer from myopia.

The probability that one individual does not suffer from myopia is 1 - 0.381 = 0.619. Since the two individuals are chosen randomly and independently, the probability that the second individual does not suffer from myopia is also 0.619.

Therefore, the probability that neither of them suffer from myopia is 0.619 * 0.619 = 0.382161.
