Answer:
28 degrees
Step-by-step explanation:
A triangle is always equal to 180 degrees so add the degrees together
40+2x+3x=180
40+5x=180
5x/5=140/5
x=28

Answer:
1.) The 1ˢᵗ three term is (-32), (-7) and 18
2.) The 1ˢᵗ three term is 127, 106 and 85
Step-by-step explanation:
1.)Here,
First Term = a₁ = - 32
Common Difference = (d) = 25
Now, For 1ˢᵗ three term,
n = 1
a₁ = - 32
n = 2
aₙ = a + (n - 1)d
a₂ = (-32) + (2 - 1) × 25
a₂ = (-32) + 1 × 25
a₂ = (-32) + 25
a₂ = -7
n = 3
aₙ = a + (n - 1)d
a₃ = (-32) + (3 - 1) × 25
a₃ = (-32) + 2 × 25
a₃ = (-32) + 50
a₃ = 18
Thus, The 1ˢᵗ three term is (-32), (-7) and 18
2.)Here,
First Term = a₁ = 127
Common Difference = (d) = -21
Now, For 1ˢᵗ three term,
n = 1
a₁ = 127
n = 2
aₙ = a + (n - 1)d
a₂ = 127 + (2 - 1) × (-21)
a₂ = 127 + 1 × (-21)
a₂ = 127 - 21
a₂ = 106
n = 3
aₙ = a + (n - 1)d
a₃ = 127 + (3 - 1) × (-21)
a₃ = 127 + 2 × (-21)
a₃ = 127 - 42
a₃ = 85
Thus, The 1ˢᵗ three term is 127, 106 and 85

Which of the following relations is a function?
a
{(1, 1), (1, 2), (1, 3)}
b
{(0, 0), (0, 1), (1, 2)}
c
{(2,0), (3, 2), (5, 2)}
d
{(3, 1), (4, 1), (3, 2)}
Answer:
C is a function
Step-by-step explanation:
For every input in a relation, there should only exist one unique output. For example, in option A, the input 1 has 3 outputs which does not make it a function since they all have to be unique. Additionally, B and D aren't functions for the same reasons. Therefore, C is a function.

Step-by-step explanation:
1. isosceles triangle
2. 3x + 15 = 90 x = 25
x + 25 = 90 x = 65
x + 55 = 90 x = 35
3. The size for DAB is 84
My reasoning is I went from one angle to another by subtracting 180 from my answers. For example angle 132 is supplementary to the missing angle next to it. I subtract 180 from 132 and get 48. That already solves the 2 equivalent angles in the triangle so I have 48+48+x = 180 because a full triangle equals 180. I get x = 84 then I do the same thing I did with angle 132. Angle 84 is supplementary to the missing angle next to it. I subtract 84 from 180 and get 96 then go diagonal from angle C (which is 96) to angle A. Those are supplementary so I subtract 96 from 180 and get 84.
Triangle ABC is similar to triangle DEF. What is the value of x ?
Answer:
A
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{AC}{DF}[/tex] = [tex]\frac{BC}{EF}[/tex] , substitute values
[tex]\frac{45}{x+8}[/tex] = [tex]\frac{30}{25}[/tex] ( cross- multiply )
30(x + 8) = 1125 ( divide both sides by 30 )
x + 8 = 37.5 ( subtract 8 from both sides )
x = 29.5 → A

In the triangle ABC
are drawn two sides
of it, BB1 and AA1.
Those half-edges
intersect at point O.
What is the length of
the semicircular BB1
if B10 = a cm?
Answer:
3a
Step-by-step explanation:
What we have as the point O refers to the centroid of the triangle
The centroid splits the distance between the opposite vertex and the middle of the side length that faces it into two; with the longer side being twice the length of the shorter
So what we have here is that;
B1O is half the length of BO
So, if B1O is a cm, BO would be 2a
So we have the entire side length measure as;
a + 2a = 3a

A local high adventure park has a zip line that begins 46 feet in the air. The angle of elevation of the cable is 35º. Estimate the length of
the zip line cable. Round your answer to the nearest hundredth if necessary.
Answer: [tex]80.2\ ft[/tex]
Step-by-step explanation:
Given
Zipline begins [tex]h=46\ ft[/tex] in the air
The angle of elevation is [tex]35^{\circ}[/tex]
Assume the length of the cable is l
from the figure, we can write
[tex]\Rightarrow \sin 35^{\circ}=\dfrac{46}{l}\\\\\Rightarrow l=\dfrac{46}{\sin 35^{\circ}}\\\\\Rightarrow l=80.19\approx 80.2\ ft[/tex]
Sales Tax: At the movie theater, a bucket of popcorn costs $8.00 and a soda costs $2.50. How much will you pay in sales tax if the rate is 6%?
We have to pay $0.63 sales tax if the rate is 6%.
What is the sales tax?
Sales tax is a tax that is added to the price of goods or services when they are sold. It is typically a percentage of the purchase price and is collected by the seller from the buyer.
In this case, the price of the bucket of popcorn is $8.00 and the price of the soda is $2.50. If the sales tax rate is 6%, the total amount of sales tax paid on the popcorn would be $8.00 x 6/100 = $0.48 and on soda is $2.50 x 6/100 = $0.15. So the total amount of sales tax paid on both items is $0.48 + $0.15 = $0.63
Hence, we have to pay $0.63 sales tax if the rate is 6%.

The volume of a cone-shaped hole is 25 pi ft cubed . If the hole is 3 ft deep, what is the radius of the hole?
Answer:
5ft
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Volume = 25π ft cubed
Depth = 3 ft
So, we can calculate the radius by using following formula,
V = 1/3 ×π ×radius squared×depth
25π = 1/3×π×radius squared ×3
Radius squared = 25
Radius = √25
Radius = 5 ft
Hence the radius of the hole is 5 ft.
find the area of the shaded region. Use 3.14 for pi
Answer:
This shaded region is consisted of 2 shapes: a right triangle and a semi-circle. To find the overall area, we must first find the are of the 2 shapes and add them together.
Step-by-step explanation:
1. Find the area of the right triangle:
a = 14, b = 2r = 8cm
A1 = ab/2 = 112/2 = 56cm²
2. Find the area of the circle:
r = 4 cm
A2 = πr² = 3.14 × 4² = 50.24cm²
3. Divide the area of the circle to get the area of the semi-circle:
A3 = A2/2 = 50.24/2 = 25.12cm²
4. Add the areas of the right triangle and the semi-circle together:
A1 + A3 = 56 + 25.12 = 81.12cm²

Need help! I’m rlly struggling with this math. Can anyone explain how to do it?
=======================================================
Explanation:
As you can probably guess, the first equation [tex]a_1 = 3[/tex] says that the first term is 3. The small '1' indicates "first term". So writing [tex]a_2[/tex] represents the second term, then [tex]a_3[/tex] is notation for the third term, and so on.
The second term is found by plugging in n = 2 into the second equation and computing to get...
[tex]a_n = 4*a_{n-1} + 2\\\\a_2 = 4*a_{2-1} + 2\\\\a_2 = 4*a_{1} + 2\\\\a_2 = 4*3 + 2\\\\a_2 = 12 + 2\\\\a_2 = 14\\\\[/tex]
The second term is 14. The steps above basically say: "to get the second term, we multiply the first term by 4, then add on 2"
In other words,
second term = 4*(first term) + 2
second term = 4*(3) + 2
second term = 12 + 2
second term = 14
-----
This can be extended to get the third term
third term = 4*(second term) + 2
third term = 4*(14) + 2
third term = 56 + 2
third term = 58
and finally,
fourth term = 4*(third term) + 2
fourth term = 4*(58) + 2
fourth term = 232 + 2
fourth term = 234
