The population here refers to the all the wild elephants that are present in that particular geography. This refers to the whole universe of wild elephants present in the area,

The sample is the 400 elephants that the biologist tranquilized to mesaure the length of their tusks.

So, to conclude, population = all wild elephants present and sample = 400 elephants that were tranquilized

The population is all of the wild elephants. The sample is the 400 wild elephants selected.

Question

A 20-foot ladder is leaning against a tree. The bottom of the ladder is 12 feet away from the bottom of the tree. Approximately how high up the tree does the top of the ladder reach? /2.4 feet/ /6 feet/ /9.2 feet/ /16 feet/

Solution 1

Pythagorean theorem is a^2 + b^2 = c^2. the hypotenuse is always the longest, so lets plug in the values.

a^2 + 12^2 = 20^2

if we simplify, we get a^2 + 144 = 400

then subtract 400-144 = 256

then find the sq. root of 256 = 16.

the answer is 16 feet

a^2 + 12^2 = 20^2

if we simplify, we get a^2 + 144 = 400

then subtract 400-144 = 256

then find the sq. root of 256 = 16.

the answer is 16 feet

Question

Tyler needs at least $305 for a new video game system. He has already saved $55. He earns $10 an hour at his job. Write and solve an inequality to find how many hours he will need to work to buy the system?

Solution 1

The first step for creating our expression is to know that $10 is the amount that depends on how many hours he works. This means that $10 will have an x variable by it. Since we are trying to get a total of $305,, the expression will equal to it and $55 will be our constant. This looks like the following:

55 + 10x = 305

Now we can start to solve by moving the constant to the right side of the equation and then change its sign.

10x = 305 - 55

Subtract the numbers on the right side of the equals sign.

10x = 250

Finally,, divide both sides of the equation by 10 to get your final answer.

x = 25

This means that Tyler needs to work 25 hours in order to buy the video game system.

55 + 10x = 305

Now we can start to solve by moving the constant to the right side of the equation and then change its sign.

10x = 305 - 55

Subtract the numbers on the right side of the equals sign.

10x = 250

Finally,, divide both sides of the equation by 10 to get your final answer.

x = 25

This means that Tyler needs to work 25 hours in order to buy the video game system.

Question

How to draw a model to show 5.5 divided by 5

Solution 1

**Answer:**

1.1

**Step-by-step explanation:**

Question

What is 98% more then 1170

Solution 1

98/100 x 1170 = 1146.6

1170 + 1146.6 = 2316.6

2316.6 is 98% more than 1170

1170 + 1146.6 = 2316.6

2316.6 is 98% more than 1170

Solution 2

More than means increase, so you have to increase 1170 by 98%.

1170×98=114660

114660÷100=1146.6

1170+1146.6=2316.6

answer=2316.6

1170×98=114660

114660÷100=1146.6

1170+1146.6=2316.6

answer=2316.6

Question

Care sunt valorile lui a , b, si c daca a+2×b+3×c=19

Solution 1

A:

a + 2 x b + 3 x c = 19

a + 2 x b + 3 x c + −2 x b = 19 + −2 x b

a + 3 x c = −2 x b + 19

a + 3 x c** +**** −****3 x c** = −2 x b + 19 **+ ****−****3 x c**

**a =**** −**** 2 x b**** − ****3 x c**** +**** 19**

Just continue like this now you just have to plug them in and then solve for each one until you get a solid answer for one variable and then plug them in to find the rest.

a + 2 x b + 3 x c = 19

a + 2 x b + 3 x c + −2 x b = 19 + −2 x b

a + 3 x c = −2 x b + 19

a + 3 x c

Question

Write a proportion that can be used to convert 50 meters into kilometers. Solve the proportion

Solution 1

So in a kilometer, there is 1,000 meters

so if you have 50 meters you can divide by 1,000 meters like:

50 meters/1 = 1 km/1,000 meters

which should get you 0.05 km

so if you have 50 meters you can divide by 1,000 meters like:

50 meters/1 = 1 km/1,000 meters

which should get you 0.05 km

Question

What is 1.44 ÷ 0.3?????

Solution 1

1.44 / 0.3 = 1.44 / (3 / 10) =

1.44 * 10 / 3 = 0.48 * 10 = answer is 4.8

1.44 * 10 / 3 = 0.48 * 10 = answer is 4.8

Solution 2

When you divide these two numbers together,, the answer is going to be 4.8. This also equals to or . Let me know if you don't happen to know how to do division with decimals,, and I would be more than happy to teach you.

Question

the area of a triangle is 2/5 square foot height is 6/5 what is. the length, in feet, of the base of the triangle?

Solution 1

A = 1/2 bh

2/5 = 1/2 b (6/5)

2/5 = 3/5 b

2/3 = b

**base is 2/3 ft **

2/5 = 1/2 b (6/5)

2/5 = 3/5 b

2/3 = b
