Trig
Let's say the height of a house is 29ft and you determined this by standing 6 feet away from the house with an angle of 75 degrees to the top of the house. If you move 24 feet away from the same house what is the new angle of elevation to the top of the house?
Answer:
50.39 degrees
Step-by-step explanation:
Model this situation with a right triangle. The horizontal leg of this right triangle is 24 ft, whereas the height (top) of the house is 29 ft, which forms the vertical leg. The ratio of these two measurements is 29/24, which is the tangent of the angle of elevation. Using a calculator to find the new angle:
tan x = 29/24 = 0.88 radian, or 50.39 degrees

Answer:
120
Step-by-step explanation:
TQR = 180 - (35+25) = 120
TQP= 180-120=60
TNP=TQP =60
MNT= 180-60=120
Celia uses 7.9 pints of blue paint and white paint to paint her bedroom walls. 2 5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Given:
Total paint used = 7.9 pints
Blue paint is [tex]\dfrac{2}{5}[/tex] of this amount.
The remaining paint is white.
To find:
The amount of white paint.
Solution:
Blue paint is [tex]\dfrac{2}{5}[/tex] of 7.9 pints.
[tex]\text{Blue paint}=7.9\times \dfrac{2}{5}[/tex]
[tex]\text{Blue paint}=3.16[/tex]
Now,
[tex]\text{White paint}=\text{Total paint}-\text{Blue paint}[/tex]
[tex]\text{White paint}=7.9-3.16[/tex]
[tex]\text{White paint}=4.74[/tex]
Therefore, the total white paint used in Celia's bedroom walls is 4.74 pints.

Here are some numbers
10 13 15 20 27 30
10 15 20 is tan arithmetic progression
Use three if the numbers to make a different arithmetic progression
Describe the rule.
Answer:
15, 27, 39
a[n] = a[n-1] +12; a[1] = 15
Step-by-step explanation:
The terms of an arithmetic progression have a common difference.
There are numbers in the given list that have differences of 5, 7, 12. The numbers with differences of 5 have already been listed. Other possible sequences are ...
13, 20, 27 . . . . common difference of 7
15, 27, 39 . . . . common difference of 12
The rule for the latter sequence is "each term is 12 more than the last" and the first term is 15.

What are the coordinates of each point after quadrilateral EFGH is translated 3 units right and 2 units down? Drag numbers to complete the coordinates. Numbers may be used once, more than once, or not at all.
Answer:
E'(-2, -3), F'(-1, -5), G'(1, -5) and H'(2, -3).
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
If a point A(x, y) is translated a units right and b units down, the new location of the point is at A'(x + a, y - b)
The location of the vertices of quadrilateral EFGH is E(-5, -1), F(-4, -3), G(-2, -3) and H(-1, -1). If quadrilateral EFGH is translated 3 units right and 2 units down, the new location would be:
E'(-2, -3), F'(-1, -5), G'(1, -5) and H'(2, -3).

Answer:
For the sugar beet part, there are 12 farms that grow sugar beet only and for the in between or the middle of the venn diagram 40 farms grow both sugar beet and potatoes, and for the one on the bottom left its 100 farms since its the total.
Step-by-step explanation:
1. Subtract 48 with 60 to get the rest of number of farms that grow sugar beet only which is 12.
2. Once we complete the 60 farms that grow only sugar beet or potatoes we add the rest which is 40 from the 100 farms to the middle which are the farms that grow both, potatoes and sugar beet.
3. Finally we add the entire total of all farms and write it down on the bottom left.

A maple syrup producer has a booth at a Sunday farmer's market. The producer sells organic maple syrup by the pint. To get customers to start buying more pints of organic maple syrup, the producer is trying out a new discount system. Customers buying more than two pint bottles will get a discount per pint, beginning with the third pint bottle. For these customers, the expression shown represents the total price, in dollars, of buying p pints of organic maple syrup. 29.50 + 13.50(p – 2)
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Price = 29.50 + 13.50(p - 2)[/tex]
The question has missing details. However, I will solve on a general term.
A possible question could be to find the cost of purchasing (say 10 bottles).
To do this, we simply substitute 10 for p.
So:
[tex]Price = 29.50 + 13.50(p - 2)[/tex]
[tex]Price = 29.50 + 13.50(10 - 2)[/tex]
[tex]Price = 29.50 + 13.50 * 8[/tex]
[tex]Price = 29.50 + 108[/tex]
[tex]Price = 137.50[/tex]
i.e. $137.50 for 10 pint bottles
Another possible question is to calculate the number of pint bottles that amount to (say $70).
To do this, we simply substitute 70 for Price.
So:
[tex]Price = 29.50 + 13.50(p - 2)[/tex]
[tex]70 = 29.50 + 13.50(p - 2)[/tex]
Collect like terms
[tex]70 - 29.50 = 13.50(p - 2)[/tex]
[tex]40.5= 13.50(p - 2)[/tex]
Divide both sides by 13.50
[tex]3= p - 2[/tex]
Add 2 to both sides
[tex]3 + 2 = p - 2 + 2[/tex]
[tex]5 = p[/tex]
[tex]p = 5[/tex]
i.e. $70 will buy 5 pint bottles

The coordinates of the vertices for the figure HIJK are H(0, 5), I(3, 3), J(4, –1), and K(1, 1). To determine if it is a parallelogram, use the converse of the parallelogram diagonal theorem. This states that if the diagonals, then the quadrilateral is a parallelogram. The midpoint of HJ is and the midpoint of IK is (2, 2). Therefore, HIJK is a parallelogram because of the diagonals, which means they bisect each other.
Answer:
In ΔHKJ and ΔHIJ
HK=IJ=√17
HI=KJ=√13
HJ=HJ [Common}
ΔHKJ ≅ ΔHIJ [SSS]
Now consider ΔHKI AND ΔKJI
HK=IJ=√17
HI=KJ=√13
KI=KI [Common]
ΔHKI ≅ ΔKJI [SSS]
Now the converse of Parallelogram diagonal theorem also states that if diagonals of a Quadrilateral divides it into two congruent triangles then it is a parallelogram.
Hence the given Quadrilateral is a Parallelogram.

simplify 3(7t-5) - 2t = 4
Answer:
Step-by-step explanation:
3(7t - 5) - 2t = 4
3*7t - 3*5 - 2t = 4
21t - 15 - 2t = 4 {combine like terms}
21t - 2t - 15 = 4
19t - 15 = 4 {Add 15 to both sides}
19t = 4 + 15
19t = 19 {Divide both sides by 19}
t = 19/19
t = 1

AB describes a line.
AB has a gradient of 3 and passes through the point (1, 15)
Find the equation of line AB,
Answer:
y = 3x + 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3 , then
y = 3x + c ← is the partial equation
To find c substitute (1, 15) into the partial equation
15 = 3 + c ⇒ c = 15 - 3 = 12
y = 3x + 12 ← equation of line AB
