andres is 1.65 meters tall. At 2 p.m., he measures the length of a tree's shadow to be 40.15 meters. He stands 35 meters away from the tree, so that the tip of his shadow meets the tip of the tree's shadow. Find the height of the tree to the nearest hundredth of a meter.
Answer:
Step-by-step explanation:
For the given data the height of the tree will be 12.86.
What is the triangle?A triangle is a three-sided polygon having three edges and three vertices in terms of geometry. The sum of the inner angles of the triangle is 180°.
Given that, Andrés is 1.65 meters tall, this is obvious. He determines the length of a tree's shadow at 2 p.m. to be 40.15 meters. The tip of his shadow touches the tip of the tree's shadow while he stands 35 meters away from the tree.
Since the triangle ABC and ADF are similar, their ratio will be the same.
Suppose the height of the tree to the nearest hundredth of a meter will be x.
5.15/40.15=1.65/x
5.15x=1.65× 40.15
5.15x=66.2475
x=66.24/5.15
x=12.86
Thus, the height of the tree will be 12.86.

Step-by-step explanation:
USE STATS CALCULATOR
You are in need of a $7,500 loan, which you plan to repay over 5 years. Your credit score is currently 690. Using the rates and the online calculator below, determine how much your savings would be if your credit score were 700 instead of 690.
Answer:
$232.57
Step-by-step explanation:
1 year = 12 months
⇒ 5 years = 5 x 12 = 60 months
APR credit score of 700 or higher = 13.25%
(using the APR calculator) total payment over term of loan = $10,296.56
APR credit score of 699 or lower = 14.25%
(using the APR calculator) total payment over term of loan = $10,529.13
Savings = $10,529.13 - $10,296.56 = 232.57

Sandy bought a pair of shoes on sale for 40% off the original price and an additional 25% off the discounted price. If the shoes originally cost $60, what was the final cost, without tax, that Sandy paid for the shoes? (I ALREADY KNOW THE ANSWER. BUT I NEED THE WORK FOR THE ANSWER TO SHOW MY TEACHER) (the answer is $27)
The price is $27.00
Step-by-step explanation:
First you find 40% of 60 which is 24.
Next you subtract 24 from 60 (60-24) which equals 36.
Then you find 25% of the discounted price (36) which is 9.
Finally you subtract 9 from 36 (36-9) which is 27.
Conclusion:
So therefore the answer is $27.00.

Square ABCD is divided into 5 rectangles that all have the same area. FH = 20 and CK = KD. Find the length of BE.
Answer:
8cm
Step-by-step explanation:
The area of a shape is the amount of space it can occupy.
The length of BE is 8 units
The question is incomplete.
So, I will give a general solution
Assume that the length BE is 2/5 of length FH.
Then the length BE would be:
BE = 2/5 * FH
Substitute 20 for FH
BE = 2/5 * 20
Evaluate the product
BE = 8
Using the assumed value, the length of BE is 8 units

Answer:
Jessica scored 20 points, Letitia scored 40 points, and Sally scored 48 points.
Step-by-step explanation:
Let x represent the points Jessica score then...
Letitia scored 2x points (twice as many as Jessica) and Sally scored 2x+8 (8 more than Letitia) points.
We can use this information to set up an equation:
x+2x+2x+8=108
Combine like terms
5x+8=108
Subtract 8 from both sides
5x=100
Divide both sides by 5
x=20 (Jessica)
2x=2(20)=40 (Letitia)
2x+8=2(20)+8=48 (Sally)
Jessica scored 20 points, Letitia scored 40 points, and Sally scored 48 points.

What's the ratio for tan B
Answer:
C. [tex]tan(B) =2[/tex]
Step-by-step explanation:
Here we can see tan(B) has a opposite side of 2 and adjacent of 1.
[tex]tan(B) = \frac{opposite}{adjacent}[/tex]
[tex]tan(B) = \frac{2}{1}[/tex]
[tex]tan(B) =2[/tex]
Answer:
[tex]\textsf{tan(B)}=2[/tex]
Step-by-step explanation:
The trig ratio for tan is tan(x) = O/A
where x is the angle,
O = side OPPOSITE to the angle, and
A = side ADJACENT to the angle
For angle B:
O = 2
A = 1
Therefore, [tex]\textsf{tan(B)}=\frac{2}{1}=2[/tex]
