Don is 6 feet tall. At a given time of day, he measures his shadow to be 10 feet long.
At the same time, he measures the shadow length of a nearby tree to be 38 feet. How
tall is the tree?
Round your answer to the nearest whole foot.

Answers

Answer:

Ok, so with this problem, you would start with the equation 6/10=x/38.

Then, cross multiply:

38(6)=10x

After, you would:

38 x 6 = 228

Then:

228/10

Lastly:

x=22.8m which when rounded equals 23 ft.

oliver drove the first 90 miles of his journey in 1.5 hours and the remaining 120 miles in 3 hours. what was the total average speed

Answers

90 miles + 120 miles = 210 total miles

1.5 hours + 3 hours = 4.5 total hours.

Average speed = total distance /  total time

Average speed = 210 miles / 4.5 hours = 46 2/3 miles per hour

The total average speed for Oliver is 42 miles per hour

Given the following data:

Distance A = 90 milesDistance B = 120 milesTime A = 1.5 hoursTime B = 3 hours

To find the total average speed:

First of all, we would determine the total distance and total speed:

[tex]Total \; distance = Distance\;A + Distance\;B\\\\Total \; distance = 90+120\\\\Total \; distance = 210\;miles[/tex]

[tex]Total \; time = Time\;A + Time\;B\\\\Total \; distance = 1.5+3\\\\Total \; distance = 4.5\;hours[/tex]

Mathematically, the average speed is given by the formula:

[tex]Average\;speed = \frac{Total\;distance}{Total\;time}[/tex]

Substituting the parameters into the formula, we have;

[tex]Average\;speed = \frac{210}{4.5}[/tex]

Average speed = 42 miles per hour.

8. A submarine's elevation is -14.5 feet relative to sea level. A shark is
swimming at an elevation -56.8 feet. What is the difference in elevation
between the submarine and the shark?
a) 71.3 feet b) 56.8 feet c) 42.3 feet d) 14.5 feet

Answers

Answer:

C.)42.3

Step-by-step explanation:

If it's difficult to do subtraction with negatives, switch them to positive and subtract 14.5 from 56.8. In order to get a lesser negative number(negatives closer to -1 are greater), you have to add a positive number. My math teacher taught me this simple but effective method. This method is used for multiplication and division but it helps:

(Hate=Negative and Love=Positive)

If you hate to hate, you love.(neg. x neg=pos.)

If you hate to love, you hate(neg. x pos.=neg.)

If you love to love, you love(pos. x pos.=pos.)

If you love to hate, you hate(pos. x neg.=neg.)

c) 42.3 feet

Step-by-step explanation:

Is known :

A submarine's elevation is -14.5 feet relative to sea level. A shark isswimming at an elevation -56.8 feet.

Asked :

What is the difference in elevation between the submarine and the shark?.

Aswered :

A submarine's elevation is -14.5 feet relative to sea level - A shark isswimming at an elevation -56.8 feet

Alice got these scores in her exam English 45 out of 50. music 45%. art 25 out of 40. maths 85% which subject did Alice get her highest and lowest scores in .​

Answers

Answer:

English: 45/50 = 0.9 = 90%

Music: 45%

Art: 25/40 = 0.625 = about 63% (if you round up)

Math: 85%

As you can see: English - highest | Music - lowest

Alice got her highest score in Maths, and her lowest score in Music.

To find out which subject Alice got her highest and lowest scores in, let's compare the scores in each subject.

English: 45 out of 50 = 45/50 = 0.9 (90%)

Music: 45 % = 45/100 = 0.45

Art: 25 out of 40 = 25/40 = 0.625 (62.5%)

Maths: 85 % = 85/100 = 0.85

Now, we can see that the highest score is in Maths (85%) and the lowest score is in Music (45%).

So, Alice got her highest score in Maths, and her lowest score in Music.

"Find the measures of two supplementary angles if their measures are 3:7
Since the ratio is 3:7 we can assume that the angles are equal to 3x and 7x?"
3x+7x=180° (180° since a line is equal to that)
then solve
10x=180
x=18
then substitute x=18 in 3x and 7x
3x=54°. 4x=126°
126° and 54°

Answers

Let the two angles be 3x and 7x.

Supplementary angles add up to 180 degrees.

Therefore:

3x + 7x = 180

10x = 180

x = 18

3x = 3 * 18 = 54

7x = 7 * 18 = 126

Answer:

The two angles are 54 degrees and 126 degrees.

Intersection of the two given sets is the empty set as the sets cover two different intervals without common elements.

Correct choice is A

#2

Assume there is a union sign between sets.

The union of the two sets is both of them.

Correct choice is B

Michael bought 8 new Pokemon cards to add to his collection.
The next day his dog ate half of his collection. There are now only
40 cards left. How many cards did Michael start with?

Answers

Answer:

72

Step-by-step explanation:

I like to work backward with problems like these. I'll start out with 40. Then it says that his dog ate half of this number. Instead of dividing by 2, I'll have to multiply by two since I'm working backward.

So, now I have 80, the number of cards he had before his dog ate half of the collection. We also see that he bought 8 new Pokemon cards and added these two his collection. Instead of adding 8, I'll subtract 8 from 80, giving me 72. So, this is his original amount.

If I take this number and go back through the scenario, I can check my work.

72 + 8 = 80, 80/2 = 40

Step-by-step explanation:

The Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the other two sides. The correct computation is ...

  Hypotenuse is √(7² +7²) = √(49 +49) = √98 = 7√2

  Perimeter of pentagon is ...

     7 +7√2 +7√2 +7√2 +7 =

     Perimeter is approximately 43.70 ft.

There are two errors:

side lengths were used instead of their squares to find the hypotenusecontents of radicals were added, rather than coefficients of them

Both errors are easy to find if you know what the computation is supposed to look like.
