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.
Answers
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.

An isosceles triangle has side lengths of 16, an altitude of x, and a base of 2x. Find the length of the base.
Answers
Answer:
Step-by-step explanation:
Since the altitude of an isosceles triangle drawn from its vertex angle bisects the base, we can use the pythagorean theorem to say that:
16^2 = x^2 + x^2
256 = 2x^2
128=x^2
x = 8sqrt2.
so the base has a length of 16sqrt2.

Signs of trig functions:
Answers
Answer:
Step-by-step explanation:
Each one of the trig functions is plus in two quadrants.
The sin(theta) is plus in 2
The Tan(theta) is plus in 3
The cos(theta) is plus in 4
Rule: if the trig function is not plus, then it is minus.
So if Tan (theta) is minus it means theta is in quad 2 or quad 4
So in this case theta is either in quad 2 or quad 4.
The sin is plus, that means that theta is in quad 2.
Which statement about f(x) and its translation, g(x), is true? The domain of g(x) is {x | x > 6}, and the domain of f(x) is {x | x > 0}.

The asymptote of g(x) is the asymptote of f(x) shifted six units up.
Answers
The correct statement about f(x) is the asymptote of g(x) is the asymptote of f(x) shifted six units up.
The given functions are;
F(x) = 7x
g(x) = 7x + 6
Parent functionA parent function is the simplest function that still satisfies the definition of a certain type of function.
We can see that 6 has been added to the function f(x) to get the function g(x).
We know that when we add some constant 'c' in the function then the function gets shifted upward by 'c' units.
Therefore, we will get g(x), when we will shift f(x) upward by 6 units.
Both functions are linear functions hence, the asymptote of g(x) is the asymptote of f(x) shifted six units up.
Hence, the correct statement about f(x) is the asymptote of g(x) is the asymptote of f(x) shifted six units up.

Step-by-step explanation:
There are 150 adults and 225 children at a zoo. If the zoo makes a total of $5100 from the
entrance fees, and the cost of an adult and a child to attend is $31 dollars, how much does it cost each
for a parent and a child?
Answers
Answer:
It costs $25 for a parent and $6 for a child
Step-by-step explanation:
Let x be the cost it takes for an adult to enter, and y be the cost it takes for a child to enter then...
x+y=31
150x+225y=5100
We can write the first equation in terms of x by subtracting y from both sides...
x=31-y
Now, we can solve the system of equations by substitution (substitute 31-y for x)...
150(31-y)+225y=5100
Distribute the 150 to the terms inside of the parentheses
150(31)-150(y)+225y=5100
4650-150y+225y=5100
Combine like terms
4650+75y=5100
Subtract 4650 from both sides
75y=450
Divide both sides by 75
y=6
Plug 6 back in for y to solve for x:
x=31-y=31-6=25
It costs $25 for a parent and $6 for a child

2) How many of the coins are dimes?
3) If Karl removes 100 pennies from the jar, then what percent of the remaining coins in the jar would be pennies?
PLEASEEEE HELP ASAP!!!!!!!!!!!! IT WOULD MAKE MY LIFE!!!
Answers
Answer:
We know that there are 200 coins
10 percent of the coins in the jar are nickels.
60 percent of the jar are pennies.
So how many nickels, dimes, and pennies.
Let’s break this down.
So 200 coins and 60 percent are pennies.
so lets find pennies first, so remeber percent means “out of a hundred” so 60 percent is really 60/100 or 0.6. Multiply 0.6 by 200 and you’d get 120 pennies.
120 pennies
Now 10 percent fo the coins in the jar are nickels. Same thing, 10 percent is basically 10/100 or 0.1. 0.1 * 200 is 20.
(1) 20 nickels
Now we know that there are 120 pennies and 20 nickels. The remaining is 60 coins left which has to be dimes.
2) 60 dimes.
Now if Karl removes 100 pennies, what would the percentage be. Now there were 120 pennies. So 120-100= 20. There’d be 20 pennies left.
We have to find the percentage but remember its 100 coins gone too so.
200-100=100
So it’s asking what percent of 100 is 20. Which should be pretty simple to look at (only in this situation or any other easily definable benchmarks).
3) 20 percent are pennies.

Tiana is 25 years old. She lives with a roommate and a dog. She has worked at a fancy restaurant for 6 months. She works 40 hours per week and makes $2.13 per hour. She usually serves 45 tables per week. The average bill at the restaurant is $130 per table, and she typically receives a 20% tip. How much does she make in a typical week?
Answers
Answer:
$1,255.5 dollars per week
Step-by-step explanation:
40Hr * $2.13 = $85.2 per week from hours alone
$130 * 0.20 = $26 tip per table
$26 * 45 tables = $1,170 in tips
$85.2 + $1,170 = $1,255.2 per typical week

Step-by-step explanation:
To begin, we'll solve for y in the first equation.
-y = 3 - 2x
y = 2x - 3
Then, plug this in for y in the second equation.
9x - 6(2x-3) = 6
9x - 12x + 18 = 6
-3x = -12
x = -12/-3
x = 4
Then, you just plug your x value into one of the equations and solve for y. Personally, I think it's easiest to plug it into y = 2x - 3
y = 2(4) - 3
y = 8 - 3
y = 5

[tex]\sf{ 27 + 9y/2 - 6y = 6}[/tex]
[tex]\sf{ 27 + 9y - 12y/2= 6}[/tex]
[tex]\sf{ 27 + - 3y = 6 × 2 }[/tex]

Answer:
2. x = 3
3. x = 10 and y =2
Step-by-step explanation:
2.
From inspection, we can see that EF = 10 and KL = 5
Therefore the ratio KL : EF = 5 : 10 = 5/10 = 1/2
This means that the side measures of ΔJKL are 1/2 the corresponding side measures of ΔGEF
Therefore, if GF = 22, then JL = 22 ÷ 2 = 11
So: 2x + 5 = 11
⇒ 2x = 11 - 5 = 6
⇒ x = 6 ÷ 2 = 3
x = 3
3.
From inspection, we can see that DF = 12 and HJ = 9
Therefore the ratio DF : HJ = 12 : 9 = 12/9 = 4/3
This means that the side measures of ΔDEF are 4/3 times the corresponding side measures of ΔHGJ
Therefore, if HG = 6, then DE = 6 x 4/3 = 8
So: 2y + 4 = 8
⇒ 2y = 8 - 4 = 4
⇒ y = 4 ÷ 2 = 2
y = 2
Similarly, if GJ = 24, then EF = 24 x 4/3 = 32
So: 4x - 8 = 32
⇒ 4x = 32 + 8 = 40
⇒ x = 40 ÷ 4 = 10
x = 10
