Answer:
4 7/8
Step-by-step explanation:
First we need to gte the denominators the same!
So we multiply the 1/4 by 2
1/4 x 2 = 2/8
Now we subtract the 2/8 from 5 1/8 to get our answer :)
5 1/8 - 2/8 = 4 7/8
Your final answer will be 4 7/8 :)
Have a great day!

which of the following is not a pythagorean triple
(5,12,13)
(8, 15 17)
(5, 8, 9)
(6, 8, 10)
Answer:
C. (5, 8, 9)
Step-by-step explanation:
Put the triples into the Pythagorean Theorem and see if they come out true.
a² + b² = c²
5² + 12² = 13²
25 + 144 = 169
169 = 169
5, 12, and 13 are a Pythagorean Triple.
a² + b² + c²
8² + 15² = 17²
64 + 225 = 289
289 = 289
8, 15, and 17 are a Pythagorean Triple.
a² + b² = c²
5² + 8² = 9²
25 + 64 = 81
89 ≠ 81
5, 8, and 9 are NOT a Pythagorean Triple.
a² + b² = c²
6² + 8² = 10²
36 + 64 = 100
100 = 100
6, 8, and 10 are a Pythagorean Triple.
royalred just started production of a new synthetic motor oil they have overhead costs of $21,804.00 a month plus manufacturing costs of $4.99 per quart of oil the oil sells for $7.36 per quart and the company's profit per month can be determined by the function p(x)=2.37x-21,804, where x is the number of quarts of oil sold over which of the following intervals will the company be making a profit
a: 2,962, 10,580
b: 9,201, 18,860
c: 2,932, infinite
d: 9,200, infinite
Considering the given profit function, it is found that the interval of values of x for which the company makes a profit is:
d: 9,200, infinite.
What is the profit function?Considering x as he number of quarts of oil sold, the monthly profit function is given by:
p(x) = 2.37x + 21,804.
The company makes a profit if p(x) > 0, hence:
p(x) > 0
2.37x + 21,804 > 0
x > 21,804/2.37
x > 9,200.
Which means that option D is correct.

Write an equation (a) in slope-intercept form and (b) in standard form for the line passing through (1,8) and perpendicular to 3x + 5y = 1
Step-by-step explanation:
a) 2y = 3x + 4
b) given the perpendicular
3x + 5y = 1
5y = 1 - 3x
y = 1/5 - 3x/5
m¹ = -3/5
perpendicular
m¹m² = -1
-3m²/5 = -1
m² = 5/3
so (1,8)
x¹ = 1 y¹ = 8
m² = (y - y¹)/(x - x¹)
5/3 = (y - 8)/(x - 1)
5x - 5 = 3y - 24
3y - 5x + 5 - 24 = 0
3y = 19 + 5x

Use a recursive formula to determine the time she will complete station 5. Show your work.
Geometric Recursive Formula
f(n) = f(n − 1) • r
Answer:
f(n) = f(n − 1) • 2
Step-by-step explanation:
f(1) = 2
f(2) = 4
f(3) = 8
f(4) = 16
Geometric Recursive formula: f(n) = f(n − 1) • r
where r is the common ratio
To determine r, divide one term by the previous term:
[tex]\sf r=\dfrac{f(n)}{f(n-1)}=\dfrac{16}{8}=\dfrac{8}{4}=\dfrac{4}{2}=2[/tex]
Therefore, f(n) = f(n − 1) • 2

A triangle has two sides of length 1 and 8. What is the smallest possible whole-number length for the third side?
Answer:
8
Step-by-step explanation:
For the smallest possible length, this has to be one of the shorter sides. Let the length of this side be x.
So, by the triangle inequality theorem, 1+x>8, which means x>7.
So, the smallest possible whole number length is 8.
Find the Area of the shaded part.
To find the area of the shaded part we have to subtract the rectangle area from the triangle area :
[tex]s = \frac{1}{2} \times (8x + 2)(6x) - (x)(3x + 1) \\ [/tex]
[tex]s = \frac{1}{2} \times (48 {x}^{2} + 12x) - (3 {x}^{2} + x) \\ [/tex]
[tex]s = \frac{48}{2} {x}^{2} + \frac{12}{2} x - 3 {x}^{2} - x \\ [/tex]
[tex]s = 24 {x}^{2} + 6x - 3 {x}^{2} - x[/tex]
[tex]s = 24 {x}^{2} - 3 {x}^{2} + 6x - x[/tex]
[tex]s = 21 {x}^{2} + 5x[/tex]

In an amusement park ride, a rider suspended by cables swings back and forth from a tower. The maximum speed v (in meters per second) of the rider can be approximated by v=2gh, where h is the height (in meters) at the top of each swing and g is the acceleration due to gravity (g≈9.8 m/sec^2). Determine the height at the top of the swing of a rider whose maximum speed is 15 meters per second. Round your answer to the nearest tenth.
According to the equation for the maximum speed, it is found that the height at the top of the swing of the rider is of 0.8 m.
What is the equation for the maximum speed?As stated in the problem, it is given by:
v = 2gh.
In which:
v is the maximum speed.g is the gravity.h is the height.In this problem, the parameters are g = 9.8, v = 15. Hence we can solve for h to find the height.
v = 2gh
2 x 9.8h = 15
19.6h = 15
h = 15/19.6
h = 0.8.
The height at the top of the swing of the rider is of 0.8 m.
