A person with a height of 2 meters stand near a tree. The tree casts a shadow that is 30 meters long and the person has a shadow that is 3
meters long. What is the height of tree
Answers
9514 1404 393
Answer:
20 m
Step-by-step explanation:
The 30 m shadow of the tree is 10 times the 3 m length of the person's shadow. We expect the tree to be 10 times as tall as the person:
10(2 m) = 20 m . . . height of the tree

The original price for a jacket is $124.95. It is on sale for 20% off. Which of the following gives the best estimate of the savings?
Answers
Answer:
24.99
Step-by-step explanation:
We first must figure out the current price of the jacket, we need to multiply the original price (124.95) times .80 (1.00 - .20). Doing so we get a total of 99.96. In order to find the savings, we subtract the original price by the new price. 124.95-99.96 = a savings of 24.99
Answer:
You would be saving 24.99 dollars
Step-by-step explanation:
Find 20% of 124.95 using P(percentage in decimal form) times X(original number) and you should have your answer.

Step-by-step explanation:
7x7=49+5=54
Answer:
y = 7
Step-by-step explanation:
Alrighty, here we go!
First step is to subtract 5 from 5 and from 54. Cancel out the 5's.
After doing so, you have 7y = 49.
Now, divide 7 from 7y and from 49. Cancel out the 7's.
Now you have y = 7

Piper and her children went into a movie theater and she bought $59.50
bags of popcorn and candies. Each bag of popcorn costs $8.50 and each candy costs
$4.25. She bought 8 more candies than bags of popcorn. Graphically solve a system
of equations in order to determine the number of bags of popcorn, x, and the number
of candies, y, that Piper bought.
Answers
6 candy boxes
Step-by-step explanation :
Since they both bought their own popcorn that means they both spent $8 on popcorn making that a total of $16. Therefore we now only need to find one variable which is the number of candy boxes that they bought in order to reach the $25 total that they spent. This variable can be represented as x in the following algebraic equation.
(2*8) + 1.50x = 25
16 + 1.50x = 25 ... subtract 16 from both sides
1.50x = 9 ... divide both sides by 1.50
x = 6
Finally, we can see that Billy and Tommy bought a total of 6 candy boxes.

Fifty students are going on a field trip. Twenty of the students are boys. What percent of the students are girls?
Answers
Answer:
60% would be the correct answer
Step-by-step explanation:
The girls percentage among students is 60%.
What is a percentage?A percentage is a proportion that shows a number as parts per hundred. If we have to calculate percent of a number, divide the number by the whole and multiply by 100.
For the given situation,
Total number of students = 50
Number of boys = 20
Number of girls = [tex]50-20[/tex]
⇒ [tex]30[/tex]
Thus, girls percentage is
⇒ [tex]\frac{30}{50}(100)[/tex]
⇒ [tex]60[/tex]
Hence we can conclude that the girls percentage among students is 60%.

Step-by-step explanation:
add 5 and 2 and 9x doesn't have a like term so it stays the same
Answer:
9x + 7

Like terms are terms that have the same variables and powers. Here, for 9x, there is no other term that is multiplied by x. So, the only terms we can combine is 2 and 5 which leaves us with 9x+7.
bob is on his way home in his car. he has driven 30 miles so far, which is three-fifths of the way home. what is the total length of his drive?
Answers
The length of Bob's drive as a fraction = 5/5
Let the length of his total drive be = x
30 miles driven by Bob as a fraction =
= 3/5 of x = 30
= 3/5x = 30
= 5/x = 30 ÷ 3 ( transposing ×3 from LHS to RHS changes ×3 to ÷3 )
=5/x = 10
= x = 10 × 5 ( transposing ÷5 from LHS to RHS changes ÷5 to ×5 )
= x = 50
Now we have to see what is =
= 2/5 of 50
= 2/5 × 50
= 100/5
= 20 miles
So , total length of Bob's drive = 30 miles + 20 miles = 50 miles .
∴ The total length of Bob's drive is 50 miles .

Step-by-step explanation:
a. The personal tax collected for 2019 is $103.0 billion.
The tax in scientific notation = $1.03 x [tex]10^{11}[/tex]
b. The population in California is 39.50 million people.
The population in scientific notation = 3.95 x [tex]10^{7}[/tex]
c. Assuming that the whole population of people in Califonia are working i.e employed, the the Personal Tax Per Capita can be determined by;
Personal Tax Per Capita = [tex]\frac{income tax revenue}{taxable population}[/tex]
= [tex]\frac{103000000000}{39500000}[/tex]
= 2607.595
= 2.61 x [tex]10^{3}[/tex]
= 3.00 x [tex]10^{3}[/tex]
d. Therefore provided that the whole population of people in California for 2019 are employed, then each person pays an average of $2607.595 per annum in the year 2019.

Answer please ? Find the perimeter of the figure ( must include all sides )
Answers
Answer:
32 ft
Step-by-step explanation:
First we can add up all the sides we already know as perimeter is the sum of all the lengths of a shape. 9+6+3+4 = 22
There are two unknown side lengths in the diagram, the long one at the top, and the short one between the 3ft side and the 4ft side. Luckily these can be easily found using the given sides. Since this shape is rectangular in nature (all 90-degree angles), the top length is the same as the bottom length. We know the total bottom length to be 7ft (3+4) so the top length must be 7ft as well.
Similarly, all the vertical lengths on the right side must be equal to the 9ft length on the left side, therefore the unknown length is 3ft (9-6).
Adding on these two new lengths and our total perimeter is 22+7+3 = 32ft.

Answers
Answer:
They both need to work 3 hours to get the same amount of $14.
Step-by-step explanation:
If you have a graphing calculator handy, just graph the two expressions 3x + 5 and 4x + 2 and look for the point where they intersect. If you don't have a graphing calculator set up the equation 3x + 5 = 4x + 2. Subtract 4x from both sides to get -x + 5 = 2. Then subtract 5 from both sides to get -x = -3. Since x shouldn't be negative, divide both sides by -1. You do this because just like x is 1x, -x is -1x. After dividing, you should get x = 3.
The graph displays the function g(x) = Equals 2 cosine (x + StartFraction pi Over 2 EndFraction) minus 2.
Which function h(x) results when g(x) is translated StartFraction 7 pi Over 8 EndFraction units right and 1 unit down?
h (x) = 2 cosine (x minus StartFraction 3 pi Over 8 EndFraction) minus 1
h (x) = 2 cosine (x minus StartFraction 3 pi Over 8 EndFraction) minus 3
h (x) = 2 cosine (x + StartFraction 11 pi Over 8 EndFraction) minus 1
h (x) = 2 cosine (x + StartFraction 11 pi Over 8 EndFraction) minus 3
On a coordinate plane, a function has a maximum of 0 and minimum of negative 4. It completes one period at 2 pi. It decreases through the y-axis at (0, negative 2).
Answers
Answer:
its b on edge 2021
Step-by-step explanation:
The required function h(x) is [tex]h (x) = 2 cos (x + \frac{11\pi }{8} ) - 3[/tex] . Option d is correct.
Function g(x) = [tex]2 cos (x +\frac{\pi }{2} )- 2[/tex]
Equation which includes trigonometric operators eg sin, cos.. etc.. In algebraic processes.
Here, the phase of the curve is increase by 7π/8.
So the phase = π/2 + 7π/8
= 11 π/8
And Shift of curve along y axis is by -1.
So, the total shift = -2-1
= -3
⇒ h(x) = [tex]2 cos (x + \frac{11\pi }{8} ) - 3[/tex]
Thus, h(x) = [tex]2 cos (x + \frac{11\pi }{8} ) - 3[/tex].
