Answer:
x = 17.5
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180, that is
5x - 4 + 4x + 44 - x = 180 , simplify
8x + 40 = 180 ( subtract 40 from both sides )
8x = 140 ( divide both sides by 8 )
x = 17.5

Step-by-step explanation:
Debbie launched a toy rocket off a hill next to Lake Lakewood. The height h of the rocket in feet above the surface of the lake can be modeled by h = 340 + 100 t − 16 t 2 h=340+100t−16t 2 , where t is the time in seconds after the launch
Answer:
t = 8.69 s
Step-by-step explanation:
The height h of the rocket in feet above the surface of the lake can be modeled by :
[tex]h=340+100t-16t^2[/tex]
Let we need to find the time to reach the ground. When it reach the ground, h = 0
[tex]340+100t-16t^2=0[/tex]
We need to find the value of t.
t = 8.69 s and -2.45 s
Neglecting negative value,
t = 8.69 s
Hence, it will take 8.69 s to reach the ground.
What fraction of the students finished in less than 20 minutes
The fraction of the students finished in less than 20 minutes is 2/3
What is a fraction?A fraction represents a part of a number or any number of equal parts.
A fraction consisting of a quotient and remainder is a mixed fraction. we can convert the mixed fraction to improper fraction by first dividing the numerator by denominator and then taking the quotient as whole number and remainder as the numerator of proper fraction keeping the denominator same.
We are given the table of the time it took a group of students to complete a puzzle.
Here we can see that total frequency is 24, and the frequency that finished in less than 20 min is 16,
This means the frequency that depends on the number of students.
Therefore, 16/24 = 2/3

Identify the function shown in this graph.
Answer:
Step-by-step explanation:
Answer:
C. y = -2x - 1
Step-by-step explanation:
y = mx + b
The slope is going down so that means that the m will be negative.
We are left with two choices:
y = -2x - 1
y = -2x + 1
Check the graph again to find what point does the line intersect the vertical line (y-axis). That hits in (0, -1) or -1.
So the only answer applicable is option C.
A x=1 1/2
B x=2/3
C x=1/10
D x=7 1/2
3^(x+3) + 3^(x-1) = 4^(x+6)
Answer:

2x^3 + 8= x^4 +1296
2x^3- x^4 = 1296-8
2x^3- x^4= 1288

Let r = ⟨5, –1⟩, s = ⟨6, 0⟩, and t = ⟨–1, –3⟩. Aaron incorrectly determined 2r + 4s – 7t as ⟨41, –23⟩. Review his calculations.
2r + 4s – 7t

⟨10, –2⟩ + ⟨24, 0⟩ + ⟨7, –21⟩
⟨41, –23⟩
What mistake did Aaron make?
He added ⟨10, –2⟩ + ⟨24, 0⟩ + ⟨7, –21⟩ incorrectly.
He should have subtracted ⟨7, –21⟩ rather than add.
He did not correctly distribute 4 to both components of s.
He did not correctly distribute the negative when subtracting 7t.

David is buying a cheese wheel priced at $ 14 $14dollar sign, 14 before tax. The store charges 8 % 8%8, percent sales tax. What is the total price, including tax, David pays for the cheese wheel? $
Answer:
$15.12
Step-by-step explanation:
{10 * 0.08 = 0.8
4 * 0.08 = 0.32} (Brackets are here so you can see what I did easier and so you could see how to do it mentally.)
[0.8 + 0.32 = 1.12]
14 + 1.12 = 15.12
David is buying a cheese wheel priced at $14 on 8% sales tax.
David's pays for the cheese wheel is $15.12 .
Given:
Before-tax, the price of cheese wheel = $ 14
Sales tax on cheese wheel = 8%
Sales tax is 8% of $14
[tex]=\frac{8(14)}{100} = \frac{112}{100} = 1.12[/tex]
So, the sales tax on the cheese wheel is $1.12
The total price of the cheese wheel, including tax = $ 14 + $1.12 = $15.12
Therefore, David's pays for the cheese wheel is $15.12 .

Find the magnitude of the gravitational force
on Mars, with a mass of 6.34 x 1023 kg and a
radius of 3.43 x 106
Answer in units of N.
Answer:
6849.4
Step-by-step explanation:
m(r)(r) mass and radius equals N
The magnitude of the gravitational force on Mars is 3.6N
Newton's law of gravitation states that the force is directly proportional to the product of the two masses and inversely proportional to the square of the distance between them. It is given by:
F = G(m₁m₂)/r²
where m₁ and m₂ are mass, r is the distance, G is constant = 6.67 * 10⁻11 Nm²/kg² and F is the force.
Given m₁ = m₂ = 6.34 * 10²³, F = 3.43 x 10⁶, hence:
F = 6.67 * 10⁻¹¹(6.34 * 10²³)² / ( 3.43 x 10⁶)²
F = 3.6N
Hence the magnitude of the gravitational force on Mars is 3.6N.

Slove the system of equations by useing the substitution method. 2x - 3y=9 y=x-4
Answer:
x = 3
y = -1
Step-by-step explanation:
in this system, we are given that y = x - 4
this means that we can take the other equation and replace y with x - 4:
so 2x - 3y=9 turns into
2x -3 (x - 4) = 9
distribute -3 to x and -4:
2x - 3x + 12 = 9
add like terms and subtract 12 from both sides
-x = -3
divide both sides by -1 to get rid of the negative on x:
x = 3
now we have the value of x, so we can replace the x in y = x - 4 with the value we just got
so y = x- 4 turns into
y = (3) - 4
solve and you get
y = -1
