Answer:
87.75 or 88
Step-by-step explanation:
To find the average you add the variables together
80+90+85+96=351
And then you take that number and divide by how many variables there are
351÷4=87.75 and you can round up to 88 if you want.

Answer:
53°Step-by-step explanation:
in the dark I see two congruent triangles, so x = 53 °
Determine the intercepts of the line
Answer: x intercept= (-10,0) y intercept = (0,-40)
Just look at where the line hits the x axis for the x intercept, then those coordinates are your x intercept. Then for the y intercept, look at where the line meets the y axis and then that point's coordinates are your y intercept.
Hope this helps!
Can you help me in this question ASAP!!!

y-intercept=1000

A pipe extends from ground level to a location under the ground. Two-fifths of the way down the pipe, there is a leak. The leak's elevation is −6.2 meters.
What is the elevation of the end of the pipe that is under the ground?
Enter your answer as a decimal or as a mixed number in simplest form in the box.
Answer: -15.5
Step-by-step explanation:
I took the test
[tex]\to -6.2 \ \text{meters is}\ \frac{2}{5} = 0.4[/tex]
All way down the pipeline Down the line, [tex]100\% = 1[/tex]. The rule of two is[tex]-6.2\ meters \to 0.4[/tex], and [tex]x \ meters\to 1[/tex] Applying Cross multiplication:[tex]\to 0.4 x = -6.2 \\\\\to x = \frac{-6.2}{0.4}\\\\\to x = -15.5[/tex]
As a result, the elevation of the underground pipe end is -15.5 meters.

Find the value of f(-142) for the function below.
f(x) = -0.2(x + 223)
Step-by-step explanation:
f(x) = -0,2(x + 223)
f(-142) = -0,2(-142 + 223)
f(-142) = -0,2(81)

Write your answer using integers, proper fractions, and improper fractions in simplest form.
y = x +
Answer: y=5x + 5
Step-by-step explanation:
The standard form of an equation for a straight line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).
The slope is given as 5, so we have y = 5x + b.
To find b, enter the given point (1,10) and solve for b:
y = 5x + b
10 = 5(1) + b
b = 5
The equation of a line with slope 5 and point (1,10) is y=5x + 5.

Which parachute has a slower descent: a red parachute that falls 10 feet in 4 sec or a blue one that falls 12 feet in 6 sec?
Answer:
The red parachute
Step-by-step explanation:
In order to compare the answers you would need a common time. You could find a number both 6 and 4 factor into, but I decided to take it to one second.
I divided 10 by 4, which is 2.5. Then I took 12 and divided it by 6, which is 2. 2.5 seconds is a longer time than 2 seconds. So the red paachute has a slower decent.
How do I solveee?????????? Helppppppppppp
We can find all the roots by factoring each polynomials.
Case A :
A = 2x^4 + x^3 + 5x^2 + 4x - 12
1 is an obvious Root of this polynomial :
2 * 1^4 + 1^3 + 5*1^2 + 4*1 - 12 = 12 - 12 = 0
Thus we have A= (2x^3+3x^2+8x+12)(x-1)
Lets go further now by factoring 2x^3 + 3x^2 + 8x + 12
We can simply group them :
(2x^3 + 3x^2) + (8x + 12) =
x²(2x+3) + 4(2x + 3) =
(2x+3)(x²+4)
To conclude : A = (2x+3)(x²+4)(x-1)
So the roots are : 1, -3/2, 2i and - 2i
Case B :
B = 2x^4 - x^3 + 5x^2 - 4x - 12
An obvious root here is -1 :
same principle applies, we write B = (2x^3−3x^2+8x−12)(x+1)
Finally B = (x²+4)(2x-3)(x+1)
And the roots are -1, 3/2, 2i and -2i
Good Luck

Find the value of the variables in each figure. Explain your reasoning.
Answer: Number 7) x=14 and y=37
Number 8) x=28 and y=23
Step-by-step explanation: Number 7) Please see fig 1 in the attachment for naming of angle.
As per diagram line b||c and their transverse line a.
Using line and angle concepts.
{Corresponding angles of parallel line b||c}
{Supplementary angle of straight line}
Now combine the like term and solve for x and we get,
12x=180-12
x=14
For line a, 4y-10+3x=180 {Supplementary angle of straight line}
where, x=14
So, we get 4y-10+3(14)=180
4y=180-32
y=37
Number 8) Please see fig 2 in the attachment for naming of angles.
As per given diagram a||b||c and line d is transversal of all three line.
Using line and angle concepts.
{Corresponding angles of parallel line a||b}
{Supplementary angle of straight line}
3y+5y-4=180
8y=184
y=23
3y=2x+13 {Corresponding angles of parallel line b||c}
we calculated y=23 substitute into above equation and we get
3(23)=2x+13
2x=69-13
x=28

I really only need help with part C
Answer:
part A: 72
part B=7
part C=7(5+9)
Step-by-step explanation:
A=the lowest common multiple found in both the 9 and 8 times table. 8s=8 16 24 32 40 48 56 64 72
9s=9 18 27 36 45 54 63 72
B=7 because 35=5×7 and if we break down 63,it
would be 9×7 or 3×3×7
C=7(5+9) because if we expand the brackets it would
be 7×5+7×9=35+63
Hope it helps?
The lowest common factor of 8 and 9 is 72, the greatest common factor of 35 and 63 is 7, and the expression (35 + 63) can be written as 7(5 + 9).and this can be determined by using the arithmetic operations.
A)
Given :
Numbers - 8 and 9
The lowest common factor of 8 and 9 is:
8 --- 8, 16, 24, 32, 40, 48, 56, 64, 72
9 --- 9, 18, 27, 36, 45, 54, 63, 72
So, the lowest common factor of 8 and 9 is 72.
B)
Given :
Numbers -- 35 and 63
The greatest common factor of 35 and 63 is:
35 = 5 [tex]\times[/tex] 7
63 = 3 [tex]\times[/tex] 3 [tex]\times[/tex] 7
So, the greatest common factor of 35 and 63 is 7.
C)
Given :
Expression -- 35 + 63
35 + 63 = 7(5 + 9)
= 7 [tex]\times[/tex] 5 + 7 [tex]\times[/tex] 9
= 35 + 63
So, the expression (35 + 63) can be written as 7(5 + 9).

Your class is having a raffle for a new graphing calculator. You bought 2 raffle tickets while everyone else in your class bought 1. There are 15 people in your class in addition to you. What is the probability that you will win the calculator?
Step-by-step explanation:
so, there are 14 people with 1 ticket each, and I have 2 tickets.
that means there are 16 tickets (14+2) in the raffle.
each ticket has therefore a winning probability of 1/16.
I have 2 tickets, so my winning probabilty is therefore
1/16 + 1/16 = 2/16 = 1/8
