Answer:
155.9 = h
Step-by-step explanation:
Since it is an equilateral triangle, the angles are all 60 degrees
Call the angle on the bottom right theta
Theta = 60 degrees
The angle h makes with the base is 90 degrees so it is a right triangle
sin theta = opp/ hyp
sin 60 = h/ 180
Multiply each side by 180
180 sin 60 = h
155.8845727 = h
To the nearest tenth
155.9 = h

Which equation represents the line that passes through
the points (-7, 1) and (5, -5)?
Answer:
Answer; y= -x/2 -5/2 OR
2y= -x-5 or
2y +x +5 =0
Step-by-step explanation:
To solve this question, you first find the gradient. For this question the gradient is -1/2. After that, you take one of the points and fix it into this equation: y -y^1 = m(x -x^1).
m =gradient or slope of the line.

Chuy purchased a used truck for
$11,500. According to an online
vehicle website, his truck will
depreciate, or lose value, at a rate of
5.5% each year. What function, d(x),
represents the value of Chuy's truck
x years after its purchase?
Answer:
d(x) = 11500*0.945^x
Step-by-step explanation:
Chuy's truck loses 5.5% of its value each year. That means each year:
(current worth of truck) = (previous year's worth) - (previous year's worth)*5.5%
The current worth is also equivalent to (previous year's worth)*94.5%.
After one year, the worth is (first year)*94.5%.
After two years, the worth is ((first year)*94.5%)*94.5%.
Note that each year, the original value of the car is multiplied by 94.5% to get the current worth. Recall also that 94.5% = 0.945.
d(x) = 11500*0.945^x, where 11500 is the original price.
Final answer:
The function representing the value of Chuy's truck x years after purchase, given a depreciation rate of 5.5% annually, is [tex]d(x) = 11500(1 - 0.055)^x[/tex]. This formula calculates the truck's decreasing value over time.
Explanation:
The question asks for the function d(x), which represents the value of Chuy's truck x years after its purchase, given it depreciates at a rate of 5.5% annually. The general formula to calculate depreciation using a percentage rate is
[tex]V = P(1 - r)^x[/tex]
where V is the future value of the item, P is the initial purchase price, r is the annual depreciation rate (in decimal form), and x is the number of years.
In this case, Chuy's truck was purchased for $11,500, and it depreciates at a rate of 5.5% per year. Substituting these values into the formula, we get the function for the value of the truck as-
[tex]d(x) = 11500(1 - 0.055)^x[/tex]
This equation allows us to determine the truck's value at any amount of years after the purchase.

A handicap ramp that is 25 feet long coves a ground distance of 22 feet. To the nearest degree, what is the angle of elevation of incline for the handicap ramp?
Answer:
28.36°
Step-by-step explanation:
The problem represents a right angled triangle as shown in the diagram below.
The length of the handicap ramp is 25 feet.
The side ground distance covered by the ramp is the adjacent of the angle of the triangle and it is 22 feet.
To find the angle of elevation of the incline, we apply SOHCAHTOA:
cos θ = adj / hyp
Therefore:
[tex]cos \alpha = 22 / 25\\\\cos \alpha = 0.88\\\\\alpha = cos^{-1} 0.88\\\\\alpha = 28.36^o[/tex]
The angle of elevation of the incline for the handicap ramp is 28.36°.

The greater of two numbers is six more than 4 times the smaller. Their sum is 41. Find the number
Answer:
smaller number is 7
larger number is 35
Step-by-step explanation:
Let the smaller number be x
Given that greater number is 6 more than 4 times the smaller number.
If x is value of smaller number then 4 times the smaller number is 4*x= 4x
six more than 4 times the smaller number will be 6+4x.
Thus larger number is 6+4x
Sum of smaller and larger no is 41.
Substituting the value of smaller and larger number in sum we have
x+6+4x = 41
=> 5x+6 = 41
=> 5x = 41-6
=> 5x= 35
=>x = 35/5 = 7
Thus smaller number is x = 7
larger number = 4x+6 = 4*7+6 = 35
To find the two numbers, we can set up two equations and solve them using substitution and simplification. The smaller number is 7, and the larger number is 34.
Explanation:To solve this problem, we can set up two equations.
Let's call the smaller number 'x' and the greater number 'y'.
From the given information, we know that:
y = 4x + 6 (Equation 1)
x + y = 41 (Equation 2)
Now, we can substitute Equation 1 into Equation 2 to solve for 'x':
x + (4x + 6) = 41
Combining like terms, we have:
5x + 6 = 41
Next, subtracting 6 from both sides gives:
5x = 35
Finally, dividing both sides by 5 gives:
x = 7
So, the smaller number is 7.
Plugging this value back into Equation 1:
y = 4(7) + 6 = 34
Thus, the larger number is 34.

One coastal cholla cactus can house the nest of the cactus wren containing two adults and up to five young. Six cholla cacti are counted in a study area. What is the maximum number of wrens that could nest in the area?
Answer:
The maximum number of wren that could nest in the area based on the number of cholla cacti is:
42 wrens.Step-by-step explanation:
The information provided by the text mentions that each cholla cactus can house a nest in which two adults and a maximum of five young will live (seven in total per nest), so this information can be represented as follows:
Maximum number of wrens = number of cholla cactus * 7Since six cholla cacti are counted in the area, this value is replaced in the created equation:
Maximum number of wrens = 6 * 7 Maximum number of wrens = 42The area could house a maximum of 42 wrens, where 12 would be adults and 30 would be young at most.
The Cholula Pyramid in Mexico has a height approximately ퟐퟏퟕfeet and a base approximately ퟏퟒퟕퟔfeet by ퟏퟒퟕퟔfeet. The Cheops Pyramid (part of the Great Pyramids) is taller with an approximate height of ퟒퟖퟎfeet but with a ퟕퟓퟓfeet by ퟕퟓퟓfeet base. Determine which pyramid has the most volume
Answer:
The Cholula Pyramid has a bigger volume out of the two.
Step-by-step explanation:
The volume of a Pyramid is V=1/3Bh
Volume of the Choulula = 1/3 (2,178,576)(217)= 157,583,664
Volume of The Cheops Pyramid = 1/3 (570,025)(480)=91,204,000
157,583,664 is greater than 91,204,000
To determine the pyramid with the most volume using the formula for the volume of a pyramid.
The volume of a pyramid: To determine which pyramid has the most volume, we use the formula for the volume of a pyramid: Volume = (1/3) × base area × height.
Cholula Pyramid: Volume = (1/3) × 1456 × 121 = 7307680 cubic feet
Cheops Pyramid: Volume = (1/3) × [tex](585)^2[/tex] × 464 = 47640550 cubic feet
Therefore, the Cheops Pyramid has the most volume.
A baseball coach graphs some data and finds the line of best fit. The equation for the line of best fit is y=0.32x-20.51,where x is the number of times a bat and y is the number of hits.
How many hits should he expect from a player who is at bat 175 times?
We have been given that a baseball coach graphs some data and finds the line of best fit. The equation for the line of best fit is [tex]y=0.32x-20.51[/tex],where x is the number of times at bat and y is the number of hits.
To find the number of hits in 175 times at bats, we will substitute [tex]x=175[/tex] in our given equation as:
[tex]y=0.32(175)-20.51[/tex]
[tex]y=56-20.51[/tex]
[tex]y=35.49[/tex]
Upon rounding to nearest whole number, we will get:
[tex]y\approx 35[/tex]
Therefore, the coach would expect 35 hits from a player who is at bat 175 times.
The expected number of hits = 35.
The given line of best fit is [tex]y=0.32x-20.51.[/tex]
Given that:
x = the number of times a bat = 175.
We have to find y = ?
We plug x = 175 in the given equation.
[tex]y=0.32x-20.51\\y=0.32(175)-20.51\\y=35.49[/tex]
The integer before 35.49 is 35. [Because, number of hits can not be fraction.]
So the expected number of hits = 35.
