sam is 5 feet tall and casts a shadow 4 feet long. at the same time, a nearby tree casts a shadow 12 feet long. what is the height of the tree

Answers

Answer:

15

Step-by-step explanation:

We can just make a ratio. 5:4 = x:12. We see x=15

The height of the tree = 15m.

let us say the height of the tree=h

in this problem,

the height of the sam can be treated as perpendicular of a right-angle triangle.

while his shadow can be treated as the base of the same triangle.

now, we need to calculate the angle of elevation α

what is the angle of elevation?

it is the angle between the line of sight and the horizon.

hence,

the tangent of the angle of elevation α= height/length of the shadow

tanα= 5/4

tan α = height of the tree/length of the shadow of the tree

5/4 = h/12

h=15m

therefore, the height of the tree = 15m

Answers

Answer:

Step-by-step explanation:

e is the exponent of the number, therefore it is the number which 10 is raised by, so -4.

Which means -1.7 will be multipled by 10 raised to the -4 power, so 1 is obviously correct.

Additionally, This is in scientific form. You can also write this in standard form in decimals, 10^-4 means it is 4 decimal places ahead the original number so you can move the decimal point back 4 places and add 0s, you will see that -0.00017 is also in fact correct.

Answer:

When an oil tank is 7/12 full, it contains 5 1/4gallons. How many gallons does it hold when full?

Answers

Final answer:

To determine the full capacity of the tank, the amount of oil it contains when it is 7/12 full (5 1/4 gallons) is divided by 7/12. After conversion and calculation, the full capacity is found to be 9 gallons.

Explanation:

The student's question asks, "When an oil tank is 7/12 full, it contains 5 1/4 gallons. How many gallons does it hold when full?" To find the full capacity of the tank, we divide the amount of oil when the tank is partially full by the fraction representing how full it is.

First, convert 5 1/4 gallons to an improper fraction: 5 1/4 = 21/4 gallons. Then divide this amount by 7/12 to find the full capacity.

Full capacity = (21/4) ÷ (7/12) = (21/4) × (12/7) = (21×12) / (4×7) = 252 / 28 = 9 gallons.

So, the full capacity of the oil tank is 9 gallons.

for #3 find the x and y-intercept and graph​

Answers

Answer:

The x-intercept is at -8 and the y-intercept is at -5.

Step-by-step explanation:

When you simplify 5x + 8y = 40 into y = mx + b form, you get y = -5/8x - 5.

Answer: x-intercept is (-8,0) and y-intercept is (0,-5)

Step-by-step explanation:

5x+8y=-40

To find the x-intercept, you plug in 0 in for y.

5x+8(0)=-40

5x=-40

Then solve for x

5x/5=-40/5

x=-8

The x-intercept is (-8,0)

To find the y-intercept, you plug in 0 in for x

5(0)+8y=-40

8y=-40

Solve for y

8y/8=-40/8

y=-5

y-intercept is (0,-5)

Final answer:

For the percent of individuals with each natural eye color and the population density of each state in the United States, a bar graph is appropriate. For the number of college students who play different sports, a bar graph is also appropriate.

Explanation:

A bar graph would be an appropriate way to display the percent of individuals with each natural eye color. Each bar in the graph would represent a different eye color, and the length of the bar would represent the percentage of individuals with that eye color. This would allow for easy comparison of the different eye colors.

For the population density of each state in the United States, a bar graph would also be appropriate. Each bar in the graph would represent a different state, and the height of the bar would represent the population density of that state. This would allow for easy comparison of the population densities between states.

For the number of college students who play basketball, baseball, or soccer, a bar graph would be the most appropriate choice. Each bar in the graph would represent a different sport, and the height of the bar would represent the number of students who play that sport. This would allow for easy comparison of the number of students playing each sport.

Two students wrote the following numerical expressions.
Angeline: (7 + 15) × (38 + 15)
MeiLing: 15 × (7 + 38)
Are the students’ expressions equivalent to your answer in Problem 4? Explain your answer.

Answers

Answer:

The expression are not equivalent.

Step-by-step explanation:

For Angeline we have the next process:

[tex](7+15)\times(38+15)=22\times53=1166[/tex]

For MeiLing we have:

[tex]15\times(7+38)=15\times45=675[/tex]

Then we have that the students expressions are not equivalent.

The process to solver the expressions was solving first the parenthesis and after that solver the multiplication.

Angeline's and MeiLing's expressions are not equivalent; Angeline's result is 1166 whereas MeiLing's is 675, due to different placement of parentheses and the main operator used.

To determine if the expressions provided by Angeline and MeiLing are equivalent, we must first simplify both expressions using the order of operations.

Angeline's expression is: (7 + 15) × (38 + 15). First, we perform the additions inside the parentheses:

7 + 15 = 22

38 + 15 = 53

Now we multiply the sums:

22 × 53 = 1166

MeiLing's expression is: 15 × (7 + 38). Again, we first add the numbers inside the parentheses:

7 + 38 = 45

And then multiply by 15:

15 × 45 = 675

Angeline's result is 1166 and MeiLing's result is 675, so the two expressions are not equivalent. It's the placement of the parentheses and the use of the main operator that leads to different results. This illustrates the importance of following the proper mathematical rules and sequence of operations to get the correct answer.
