Mr. Hodges wants to build a fence around his entire rectangular garden. What is the total distance around the garden?
30 feet with 6 yards

Matthew traveled a total of 43 blocks.

To calculate the total blocks traveled by Matthew, we need to add up the distances he walked and the distances he rode on the bus. He walked 7 city blocks, rode 13 blocks on the bus, and then walked 1 and a half blocks to the store. To return home, he traveled the same route, so we can double the distance. Adding all these distances together, Matthew traveled a total of 7 + 13 + 1.5 + 7 + 13 + 1.5 = 43 blocks.

Final answer:

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.

First open the bracket by multiplying with -2

-2x - 26 +9x = 4

Solving like terms

7x - 26 = 4

Adding 26 to both sides

7x - 26 +26 = 4+26

7x = 30

X = 30/7

[tex]-2(x+13)+9x=4\\\\-2x-26+9x=4\\\\7x=30\\\\x=\dfrac{30}{7}[/tex]

The equation for this is x2-x1/y2-y1 and so you plug in the numbers and get -5/7, and that is your slope.

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.

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.

I hope this helps!

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.

Step-by-step explanation:

Assume camel stays at the market after complete delivery.

Idea is to drop off some bananas between the plantation and the market.  Refrigeration is required to avoid bananas going bad!

Status (planatation, 250 mile point, 500 mile point, market)

First trip with 1000 bananas, stop at 250 miles, drop off 500 bananas, and come back to plantation.  (status:  2000, 500, 0, 0) camel ate 500 bananas.

Second trip with 1000 bananas, stop at 250 miles, pick up 250 (to make 1000), drop off 250 at 500 mile point, come back to plantation.  (Status: 1000, 250,250,0) Camel ate 1500 bananas.

Last trip with 1000 bananas, stop at 250 miles, fill-up 250 (total 1000), stop at 500 miles, fill-up to make total 1000.  Travel all the way to market with 500 left.

(Status: 0,0,0,500) Camel ate 500+1000+1000.

Net delivery: 500 bananas to market.

Using the camel to transport bananas across the desert, George loses all bananas to the camel's consumption before reaching the market, resulting in 0 bananas delivered.

The question asks how many bananas can George, the plantation owner, transport to the market across a 1000 mile stretch of desert using a camel that can carry 1000 bananas and eats one per mile. George has 3000 bananas to start with.

To maximize the number of bananas delivered, George must use a strategy that conserves bananas while accounting for the camel's consumption. For the first trip, George loads the camel with 1000 bananas, travels 333 miles (eating one banana per mile), deposits 667 bananas, and returns with 0. He repeats this until all bananas are 333 miles into the desert. This requires three round trips for the first third of the journey, resulting in the loss of 2000 bananas and leaving 1000 bananas 333 miles into the desert.

Next, he takes 1000 bananas, goes another 500 miles (leaving 500 bananas), and returns for the last batch of 500. This leaves him with 500 bananas 500 miles into the desert. Finally, he carries the last 500 bananas the remaining distance of 500 miles to the market, arriving with 0 bananas. Therefore, the greatest number of bananas George can deliver to the market is 0. This proves that it is impossible to deliver any bananas to the market under the given conditions.

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

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.

If the speed in still air is s, and the wind speed is w,

580/(s+w) = 5

580/(s-w) = 10

s=87

w=29

Final answer:

To determine the speed of the plane in still air and the speed of the wind, we use the distances and times provided to create two equations. Solving this system reveals that the speed of the plane in still air is 87 mph and the speed of the wind is 29 mph.

Explanation:

To find the speed of the plane in still air and the speed of the wind, we can set up a system of equations based on the given information. We'll let p represent the speed of the plane in still air and w represent the speed of the wind.

When the plane travels with the wind, its effective speed is p + w, and the time taken for the trip is 5 hours, covering 580 miles. So, our first equation is:

1) (p + w) * 5 = 580

When the plane returns against the wind, its effective speed is p - w, and the time taken for this trip is 10 hours, again covering 580 miles. Thus, our second equation is:

2) (p - w) * 10 = 580

Solving this system of equations, we'll start by simplifying both:

p + w = 116 (By dividing the first equation by 5)

p - w = 58 (By dividing the second equation by 10)

Now we can add both equations to eliminate w:

2p = 174

Divide by 2 to get the speed of the plane in still air:

p = 87 mph

To find the speed of the wind, substitute the value of p in one of the equations:

87 + w = 116

So, the speed of the wind is:

w = 116 - 87

w = 29 mph

The speed of the plane in still air is 87 mph, and the speed of the wind is 29 mph.

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.

c.(4.1)+(2.3)=6.4

Answer : b) 13/16

Given : t varies as v

So t = k v  where k is the constant of proportionality.

t = 2 4/7 when v =13/14. Using these values we find out k

[tex]t = 2\frac{4}{7} =\frac{18}{7}[/tex]

[tex]v =\frac{13}{14}[/tex]

t = k * v

[tex]\frac{18}{7}= k *\frac{13}{14}[/tex]

Multiply by 14/13 on both sides

[tex]\frac{18}{7} *\frac{14}{13} = k *\frac{13}{14}*\frac{14}{13}[/tex]

So  [tex]k =\frac{36}{13}[/tex]

We got the value of k. Now we find v when t = 2 1/4

[tex]t = 2\frac{1}{4} =\frac{9}{4}[/tex]

t = k * v

We know the value of t and k

[tex]\frac{9}{4}= \frac{36}{13}* v[/tex]

Multiply by 13/36 on both sides

[tex]\frac{9}{4} *\frac{13}{36} =\frac{36}{13}*\frac{13}{36}* v[/tex]

So  [tex] \frac{13}{16}= v[/tex]
