Ice cream costs $1.99 per container. At a tax rate of 4.75%, estimate the final cost of the
ice cream.
Answer:
The final cost of ice-cream container is: 2.09 dollars
Step-by-step explanation:
In order to find the price of an item after adding tax the tax is found on the price of the item and then added to the cost.
Given
Price of ice cream container = $1.99
Tax Rate = 4.75%
The amount of tax t will be:
[tex]t = 4.75\%\ of\ 1.99\\= 0.0475*1.99\\=0.094525[/tex]
Rounding off to nearest hundredth
t = 0.10
The final cost is given by:
[tex]Final\ cost = Cost + tax\\= 1.99+0.10\\=2.09[/tex]
Hence,
The final cost of ice-cream container is: 2.09 dollars

If x and y are two complementary angles,then find the value of y if measure of angle x is 20 degree
Answer:
y = 70°
Step-by-step explanation:
Complementary angles sum to 90°, then
x + y = 90°, that is
20° + y = 90° ( subtract 20° from both sides )

Step-by-step explanation:
Since the sum of the angles in a triangle is [tex]180^{\circ}[/tex], you can set the equation [tex]9x-7+7x-9+28-2x[/tex]. Simplifying gets [tex]14x=168[/tex]. Dividing gets you [tex]x = 12[/tex]. This is only x so you have to substitute 12 for x in the angles in the beginning to get [tex]\angle{A}=101^{\circ}[/tex], [tex]\\\angle{B}=75^{\circ}[/tex], [tex]\\\angle{C}=4^{\circ}[/tex]
How many turns will the graph of f(x) = 3x5 -2x4 + 7x2 -9x + 8 have?
Answer:
The number of turns of graph for [tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex] are 4
Step-by-step explanation:
We need to find the number of turns the graph of [tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex] have?
Turns of graph:
The graphs turns when it changes from increasing to decreasing (rise to fall) or decreasing from increasing (fall to rise)
Turns of graph for a polynomial
A polynomial having degree n will have maximum n-1 turns.
So, for the given polynomial
[tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex]
We need to find degree
The highest exponent of the polynomial is the degree of polynomial
So, Degree n = 5
Number of turns = n - 1 = 5-1 =4
So, the number of turns of graph for [tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex] are 4
The length of a rectangle is 3 more than the width. The
perimeter of the rectangle is 72 in.
What is the length of the rectangle?
Answer ASAP for brainly
Answer:
19.5 in.
Step-by-step explanation:
Let the width = x.
The length is 3 more than the width, so the length is x + 3.
perimeter = 2 * length + 2 * width
perimeter = 2(x + 3) + 2x
perimeter = 72
2(x + 3) + 2x = 72
2x + 6 + 2x = 72
4x + 6 = 72
4x = 66
x = 16.5
x + 3 = 16.5 + 3 = 19.5
Answer: 19.5 in.

(x+3)^2=(x+3)(x+3)=x^2+6x+9 express x^2+6x+13 in the form (x+a)^2+b giving the values of a and b
Answer:
The value of a is 3 while the value of b is 4
Step-by-step explanation:
Here, we want to express the given polynomial in the given form while giving the values of a and b
We can rewrite the polynomial as follows;
x^2 + 6x + 9 + 4
We can factorize the first part;
x^2 + 3x + 3x + 9 + 4
x(x + 3)+ 3(x + 3) + 4
= (x + 3)(x + 3) + 4
= (x + 3)^2 + 4

write the factors of the following expression x3 (2a‐6)+x2 (2a-6)
Given:
The expression is
[tex]x^3(2x-6)+x^2(2x-6)[/tex]
To find:
The factors of the given expression.
Solution:
We have,
[tex]x^3(2x-6)+x^2(2x-6)[/tex]
First taking [tex](2x-6)[/tex] common, the given expression can be written as
[tex]=(2x-6)(x^3+x^2)[/tex]
Taking [tex]x^2[/tex] common from [tex](x^3+x^2)[/tex], we get
[tex]=x^2(2x-6)(x+1)[/tex]
Therefore, the factors of the given expression are [tex]x^2(2x-6)(x+1)[/tex].
Insurance company executives surveyed 200 young adults about their first motor vehicle. The results of the survey are given in the following two-way table.
A survey participant is randomly selected. Let F be the event that the participant’s first motor vehicle had four cylinders and let C be the event that the participant’s first motor vehicle was a car. What is the value of P(F or C)?
A) 0.59
B) 0.68
C) 0.71
D) 0.80
Answer:
C) 0.71.
Step-by-step explanation:
To find the probability of an event occurring, we need to sum up all the probabilities of the outcomes that satisfy the event. In this case, the event "F or C" is satisfied by all the outcomes in which the participant's first motor vehicle had four cylinders or was a car.
We can see from the table that 118 out of the 200 participants had their first motor vehicle as a car, so the probability of this event occurring is 118/200 = 0.59. Similarly, we can see that the probability of the event "first motor vehicle had four cylinders" occurring is (118 + 4) / 200 = 0.62.
Therefore, the probability of the event "F or C" occurring is the sum of the probabilities of these two events occurring, which is 0.59 + 0.62 = 0.71. The correct answer is therefore C) 0.71.
The value of the probability P(F or C) is 0.80, Option D is correct.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given that a survey participant is randomly selected.
Let F be the event that the participant’s first motor vehicle had four cylinders and
let C be the event that the participant’s first motor vehicle was a car.
We need to find the value of P(F or C)
The number of P or c is 118+6+18+16+2
=160
The number of people in total are 200.
P(F or C )= 160/200
=0.80
Hence, the value of the probability P(F or C) is 0.80, Option D is correct.
