Answer:
a₇₆ = - 134
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 16 and d = a₂ - a₁ = 14 - 16 = - 2, then
a₇₆ = 16 + (75 × - 2) = 16 - 150 = - 134

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
( 1/8 )⁻³ᵃ = ( 512 )³ᵃ be equation (1)
On simplifying the equation , we get
when a = 0
Substitute the value of a = 0 , we get
( 1/8 )⁻³ˣ⁰ = ( 512 )³ˣ⁰
On simplifying the equation , we get
( 1/8 )⁰ = ( 512 )⁰
Any number raised to the power 0 will be 1
So , ( 1/8 )⁰ = ( 512 )⁰ = 1
1 = 1
Therefore , the value of a = 0
Hence , the equation is solved

Obasi earns 150\%150%150, percent of his regular hourly wage while working overtime. What fraction of his regular hourly wage does Obasi earn while working overtime?
Answer:
3/2 or 1 1/2
Step-by-step explanation:
We are told that:
Obasi earns 150% of his regular hourly wage while working overtime
The fraction of his regular hourly wage that Obasi earns while working overtime is written as:
150%
= 150/100
= 15/10
= 3/2
= 1 1/2
The fraction of his regular hourly wage that Obasi earns while working overtime is 3/2 or 1 1/2

Marcus spent 2 hour reading,1 hour playing Rocket League,and took a 2 hour nap. What percent of the total time did he read?
Answer: He read 40% of the total time.
Step-by-step explanation:
As per given,
Total time he spent = 2 +1+2 = 5 hours
Number of hours he spent on reading = 2 hours
The percent of the total time he read = [tex]\dfrac{\text{Number of hours read}}{\text{Total time spent}}\times100[/tex]
[tex]=\dfrac{2}{5}\times100\\\\=40\%[/tex]
i.e. The percent of the total time he read = 40%
Hence, he read 40% of the total time.

Mike drank 60% of his glass of milk. Afterwards, 80ml of milk remained in the glass. What volume of milk was initially in the glass?
Answer:
Step-by-step explanation:
[tex]x[/tex] is the total volume of milk.
100% - 60% = 40%
40% is left in the glass.
40% of [tex]x[/tex] = 80 ml
[tex]\frac{40}{100}[/tex] of [tex]x[/tex] = 80
[tex]x = 80[/tex] × [tex]\frac{100}{40}[/tex]
[tex]x = 200[/tex] ml
The volume of milk initially in the glass was 200 ml.
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100.
Let x be the total volume of milk.
100% - 60% = 40%
40% is left in the glass.
40% of x = 80 ml
40 / 100 × x = 80
0.4 × x = 80
x = 200
Thus, The volume of milk initially in the glass was 200 ml.

Isabella is deciding between two parking garages. Garage A charges an initial fee of
$4 to park plus $3 per hour. Garage B charges an initial fee of $12 to park plus $2 per
hour. Let A represent the amount Garage A would charge if Isabella parks for t
hours, and let B represent the amount Garage B would charge if Isabella parks fort
hours. Write an equation for each situation, in terms of t, and determine the hours
parked, t, that would make the cost of each garage the same.
Answer:
1. A = 4 + 3t ............ 1
B = 12 + 2t .............. 2
2. 8 hours
Step-by-step explanation:
For park A,
A = 4 + 3t ............ 1
where A is the amount paid, and t is the number of hours.
For park B,
B = 12 + 2t .............. 2
where B is the amount paid, and t is the number of hours.
The hours that would make A = B can be determined as follows.
Equate 1 and 2, so that;
A = B
4 + 3t = 12 + 2t
collect like terms
3t - 2t = 12 - 4
t = 8
The number of hours that would make the cost of each garage the same is 8.
Answer:
A= 3t+4
B= 2t+12
3t+4=2t+12
t= 8 hours

Find the distance between the two points rounding to the nearest tenth (if necessary) (6,-1) and (-1,6)
Answer:
9.89
Step-by-step explanation:
Find the distance between the two points rounding to the nearest tenth (if necessary) (6,-1) and (-1,6)
Step one:
given data
x1=6
y1=-1
x2=-1
y2=6
Step two:
The distance between two point is
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((-1-6)²+(6+1)²)
d =√((-7)²+(7)²)
d =√49+49
d=√98
d=9.89

=====================================================
Explanation:
We'll apply the arc length formula
L = theta*r
Theta is the central angle and r is the radius. This formula only works when the angle is in radian mode. In this case, theta = 4/3 radians.
Arc length AB is part of a circle that has radius r = 8, so,
L = theta*r
L = (4/3)*8
L = 32/3
That represents the length of arc AB. This length is in cm.
-----------------------
Let x be the length of segment BD. This is also the length of AC as well due to rotational symmetry.
Arc CD is part of the larger circle that has radius r = 8+x
L = theta*r
L = (4/3)(8+x)
-----------------------
We found the following lengths so far
arc AB = 32/3segment BD = xarc CD = (4/3)(8+x)segment AC = xThese four pieces form the sides of the blue region. Therefore, they form the perimeter of the blue region. Add up these four sides and set the sum equal to the given perimeter 48. Then solve for x.
(arcAB)+(segmentBD)+(arcCD)+(segment AC) = perimeter of blue region
(32/3) + (x) + (4/3)(8+x) + (x) = 48
32/3 + x + (4/3)*8+(4/3)*x + x = 48
32/3 + 2x + 32/3+(4/3)*x = 48
64/3 + 2x +(4/3)*x = 48
64/3 + 6x/3 +(4/3)*x = 48
64/3 + (10/3)*x = 48
(10/3)*x = 48-64/3
(10/3)*x = 144/3-64/3
(10/3)*x = 80/3
10x = 80
x = 80/10
x = 8
-----------------------
Since x = 8, we know that AC and BD are each 8 cm long.
This means that the larger circle has radius 8+8 = 16 cm
Now we'll apply the sector area formula. You can think of a sector as a pie slice or pizza slice. The formula shown below only works if theta is in radian mode.
Let's find the area of sector AOB. This is the smaller pie slice.
A = area of sector
A = (1/2)*theta*r^2
A = (1/2)*(4/3)*8^2
A = (1/2)*(4/3)*64
A = (1*4*64)/(2*3)
A = (2*64)/3
A = 128/3
Sector AOB is 128/3 square cm. Let's make m = 128/3 so we can use it later.
Now let's find the area of sector COD. We use the same theta value, but the radius is now 16 cm.
A = (1/2)*theta*r^2
A = (1/2)*(4/3)*16^2
A = (2/3)*256
A = 512/3
The area of sector COD is 512/3 square cm. Let n = 512/3.
-----------------------
The last thing to do is subtract the values of m and n to get the area we want.
blue area = (area of sector COD) - (area of sector AOB)
blue area = n - m
blue area = 512/3 - 128/3
blue area = (512-128)/3
blue area = 384/3
blue area = 128 square cm
