Answer:
50
Step-by-step explanation:
Given
first term (a) = 6
Common Difference (d) = 1 - 6 = - 5
Last term (tn )= - 239
Number of terms (n) = ?
We know
Tn = a + ( n - 1 ) d
- 239 = 6 + (n - 1) (-5)
- 239 = 6 - 5n + 5
- 239 = 11 - 5n
5n = 11 + 239
5n = 250
n = 250 / 5
n = 50
The number of terms is 50.

Answer:
62.5%
Step-by-step explanation:
There are a total of 8 people on the data plot.
5 of them got 15 questions or more correct, meaning 5/8 people got 15 or more questions correct.
5/8 = 5 ÷ 8
5 ÷ 8 = 0.625
0.625 = 62.5%
Please help me solve this step by step please :(
Answer:
B) 60.21 ft²
Step-by-step explanation:
Area of a triangle = 1/2bh
You can‘t used mixed measurements (feet and inches), so you have to convert each length to inches
8’6”=102’
14’2”=170’
Now find the area
1/2 x 102 x 170 = 8670 in²
This is one of the answers, but the quetion asks how many quart feet you need.
So, convert it back to feet.
8670 x 0.06944444444 = 60.2083333
(You could also have converted the two lengths to feet. 8’6” = 8.5 ft. 14’2” = 14.16666666. This way would probably have been faster.
1/2 x 8.5 x 14.166666 = 60.20833333)

A helicopter hovers 1500 feet above a small island. The
figure shows that the angle of depression from the
helicopter to point P is 40°.
How far off the coast, to the nearest foot, is the island?
400
1500ft
Please help me solve this problem
Answer:
the island is 1787.63ft far.
Step-by-step explanation:
<P=40° alternate angle
in triangle
relationship between perpendicular and base is given by tan angle
tan 40=p/b
tan40=1500/b
b=1500/tan40=1787.63ft

Step-by-step explanation:
(11+x)/2-(9x-3)/4 x=3
Answer:
(11+X)/2-(9x-3)/4 x=3
subsititute 3 into all x
(11+3)/2-(9*3)-3)/4
first solve the first diviision
2-(9 times 3)-3/4
=2-(27-3)/4
=2-(24)/4
since the "2-" is there, you have to subtract it from 24 before you dividewhich would then be
22/4=5.5(in decimal form)
DON'T forget you have another bracket waiting for you since you were given 3 brackets. bring the first bracket down
2-(9x-3)/4 was solved and we got 5.5, so basically we are "substituting 5.5 into that part of the question)
11+x/5.5
11+3/5.5
14/5.5
=2.54 which is your final answer
Sorry if I went overboard lol.
Step-by-step explanation:
yes, the answer is 2.54 I believe.
Quadrilateral ABCD is a parallelogram with < BCA= 50 , < DCA=60, find value of
Answer:
[tex]ADC = 70[/tex]
Step-by-step explanation:
Given
[tex]BCA = 50[/tex]
[tex]DCA = 60[/tex]
See attachment for parallelogram and complete question
Required
Find ADC
From the attachment:
[tex]BCD = BCA + DCA[/tex]
[tex]BCD = 50+60[/tex]
[tex]BCD = 110[/tex]
Adjacent angles add up to 180.
So:
[tex]ADC + BCD = 180[/tex]
[tex]ADC = 180-BCD[/tex]
[tex]ADC = 180-110[/tex]
[tex]ADC = 70[/tex]

Why is stock data calculated using the subtraction and addition method instead of a simple moving average? PLEASE HURRY I AM TAKING A TEST
Answer:
The moving average (MA) is a simple technical analysis tool that smooths out price data by creating a constantly updated average price. The average is taken over a specific period of time, like 10 days, 20 minutes, 30 weeks or any time period the trader chooses. There are advantages to using a moving average in your trading, as well as options on what type of moving average to use. Moving average strategies are also popular and can be tailored to any time frame, suiting both long-term investors and short-term traders.
Step-by-step explanation:
One disadvantage to solving systems using substitution is that isolating a variable often involves dealing with messy fractions. There is another method for solving systems of equations: the addition/subtraction method.
In the addition/subtraction method, the two equations in the system are added or subtracted to create a new equation with only one variable. In order for the new equation to have only one variable, the other variable must cancel out. In other words, we must first perform operations on each equation until one term has an equal and opposite coefficient as the corresponding term in the other equation.

m∠1=119∘ and m∠2=61∘.
What is m∠3?
Answer:
m∠3 = 119°
Step-by-step explanation:
All the angles must equal 360° when added together. You have two known angles that are right next to each other. If you add m∠1 and m∠2, 119 + 61, it is equal to 180°. This means that m∠3 and m∠4 must be equal to 180° as well and since there are only two lines, it is safe to assume that opposing angles are the same so m∠1 = m∠3 and m∠2 = m∠4.

Solve the equation square root of the quantity x plus 3 plus 4 equals 5 for the variable. Show each step of your solution process
Answer:
x=-2
Step-by-step explanation:
[tex]\sqrt{x+3}+4=5[/tex]
subtract 4 from each side
[tex]\sqrt{x+3} +4-4=5-4[/tex]
square both sides
[tex]\sqrt{x+3}^2=1^2[/tex]
so we have
[tex]x+3=1[/tex]
subtract 3 from each side
[tex]x+3-3=1-3[/tex]
so our answer is [tex]x=-2[/tex]
