Answer:The answer is b because c and D dong make since. An A is wrong
Step-by-step explanation:
Simplify and then evaluate the equation
when a= 2 and b = 4.
b2 + 3(b – 62) – 2a= [?]
Answer:
-170
Step-by-step explanation:
First, you would substitute 2 and 4 for a and b. 4 times 2 + 3(4 - 62) - 2 times 2 = ?
Then, do 4 times 2 (8), 3(4-62)=3(-58)
8 + -174 - 4 = -170

Colin invests £9100 into his bank account.
He receives 2.5% per year simple interest.
How much will Colin have after 3 years?
Give your answer to the nearest penny where appropriate.
Answer:
The total amount accrued, principal plus interest, from simple interest on a principal of $9,100.00 at a rate of 2.5% per year for 3 years is $9,782.50.
Step-by-step explanation:
Principle amount = P = £9100
interest rate = r = 2.5% per year
Time period = t = 3
Simple Interest = 9100 × 2.5% × 3 = £682.5
Total amount = Principal amount + Simple interest
= 9100 + 682.5
= £9782.5
Therefore, the total amount accrued, principal plus interest, from simple interest on a principal of £9,100.00 at a rate of 2.5% per year for 3 years is £9,782.50.

what is the perpendicular slope intercept form?
Answer:
The point-slope form of the equation of the perpendicular line that goes through (5, 0) is:
[tex]y=-\frac{1}{2}x+\:\frac{5}{2}[/tex]Step-by-step explanation:
Given the equation
[tex]y=2x-1[/tex]
comparing the equation with the slope-intercept form
[tex]y=mx+b[/tex]
Here,
m is the slope b is the interceptso the slope of the line is 2.
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
The slope of the perpendicular line will be: -1/2
Therefore, the point-slope form of the equation of the perpendicular line that goes through (5, 0) is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-0=\frac{-1}{2}\left(x-5\right)[/tex]
[tex]y=\frac{-1}{2}\left(x-5\right)[/tex]
[tex]\:y=-\frac{1}{2}x+5\cdot \:\frac{1}{2}[/tex]
[tex]y=-\frac{1}{2}x+\:\frac{5}{2}[/tex]

Mr. Gottula can eat two tacos in 8 minutes. Mrs. K can eat three tacos in 15 minutes.
(5a) Who eats tacos faster? How do you know? *
(5b) What is the UNIT RATE for Mr. Gottula? (In other words, how many minutes does it take for him to eat one taco?) *
(5c) At this rate, how long would it take Mr. Gottula to eat four tacos? *
(5a) Answer: Mr. Gottula eats the tacos faster
(5b) Answer: It takes Mr. Gottula 4 minutes to eat 1 taco
(5c) Answer: It will take Mr. Gottula 16 minutes to eat 4 tacos
Step-by-step explanation:
(5b) If we know that Mr. Gottula can eat two tacos every 8 minutes, and Mrs. K can eat three tacos in 15 minutes, first we have to find out how many tacos they eat in 1 minute. Finding how much they eat in one minute is mathematically called THE UNIT RATE. So to find the unit rate we have to divide the time it takes Mr. Gottula to eat the tacos by 2.
If Mr. Gottula can eat 2 tacos in eight minutes we have to find how much he can eat in one minute. So we have to divide the time Mr. Gottula took to ate by 2 and we also have to divide the tacos Mr. Gottula ate by 2. So now lets do the math, 8 divided by 2 is 4, and 2 divided by 2 is 1. So we now know the unite rate. Mr. Gottula ate 1 taco in 4 minutes. To find Mrs. k's unit rate we do the same thing, but we have to divide it by 3 since Mrs. k ate 3 tacos in 15 minutes. So we now have to find the unit rate for Mrs. k. Lets now do the math, 15 divided by 3 is 5 and 3 divided by 3 is 1. So now we know the unit rate of Mrs. k, Mrs. k ate 1 taco in 5 minutes. Mr. Gottula eats a taco every 4 minutes, while Mrs. K eats a taco every 5 minutes. So Mr. Gottula is eating faster.
(5c) So next it says "At this rate, how long would it take Mr. Gottula to eat four tacos?" So if we know that Mr. Gottula eats a taco every 4 minutes we just have to find out how many minutes will it take Mr. Gottula to eat 4 tacos. He eats 1 taco in 4 minutes so we have to multiply the tacos by 4 and we have to also multiply the time by 4 to find out how long it takes Mr. Gottula to eat 4 tacos. So lets do the math, 4 times 1 is 4 and 4 times 4 is 16 so we now know that Mr. Gottula eats 4 tacos in 16 minutes.

Damari wants to trim the circular concrete
mural with outdoor rope lighting. The mural has a
diameter of 45 feet. One rope has a length of 50
ft. Each strand costs $39.99. How much will
Damari spend in order to trim the mural with
rope lighting? Use 3.14 to approximate .
Answer:
First, let's find the perimeter of the concrete mural.
A circle of diameter d, has a perimeter:
p = d*pi
where pi = 3.14
the concrete mural has a diameter of 45 ft, then it's perimeter is:
P = 45ft*3.14 = 141.3 ft
One rope has a length of 50ft, and costs $39.99.
Let's find the number of ropes that Damari needs to use, so let's divide the perimeter in lengths of 50ft:
N = 141.3ft/50ft = 2.826
Then Damari needs 2.826 ropes, but she can not buy 0.826 of a rope, then we should round it up to 3 ropes.
Then she needs to buy 3 ropes, and she will pay 3 times $39.99, this is:
Cost = 3*$39.99 = $119.97

Tommy plans to attend the Clinton County Fair and is trying to decide what would be a better deal. He can pay $36 for unlimited rides, or he can pay $14 for admission plus $2 per ride. If Tommy goes on a certain number of rides, the two options wind up costing him the same amount. What is that cost? How many rides is that?
Let, n is the number of rides at which he pays same in both the deal.
Deal 1 :
Amount paid, A = $36 .
Deal 2 :
Amount paid, A = 14 + 2n
Equating both the equation, we get :
14 + 2n = 36
2n = 22
n = 11
Therefore, at a cost of $36 and at 11 rides both the deals are same.
Hence, this is the required solution.
Solve the absolute value equation.
│4x + 3│= 3
A. x = 0 or x = negative three over two
B. x = 0 or x = 3 over 2
C. x = 1 or x = negative three over two
D. x = 1 or x = 3 over 2
Answer:
A
Step-by-step explanation:
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is |4x+3|
For the Negative case we'll use -(4x+3)
For the Positive case we'll use (4x+3)
-(4x+3) = 3
Multiply
-4x-3 = 3
Rearrange and Add up
-4x = 6
Divide both sides by 4
-x = (3/2)
Multiply both sides by (-1)
x = -(3/2)
Which is the solution for the Negative Case
(4x+3) = 3
Rearrange and Add up
4x = 0
Divide both sides by 4
x = 0
Which is the solution for the Positive Case
x=-3/2
x=0
The solution of the absolute equation │4x + 3│ = 3 will be 0 and - 3/2. Then the correct option is A.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The absolute function is also known as the mode function. The value of the absolute function is always positive.
f(x) = |x - h| + k
The absolute function is given as,
│4x + 3│ = 3
Simplify the equation, then we have
│4x + 3│ = 3
4x + 3 = ± 3
4x = - 3 ± 3
For positive signs, then we have
4x = - 3 + 3
4x = 0
x = 0
For negative sign, then we have
4x = - 3 - 3
4x = - 6
x = - 3/2
The solution of the absolute equation │4x + 3│ = 3 will be 0 and - 3/2. Then the correct option is A.
