[this is the next question and so fourth]
and for the one after this question with three options, it is:
21.12; 0.14; 35
then for the one after that one, it is:
64.6; -20.2; 28
then for the one after that one, it is:
(A) 5.2 + 2.2x scoring 1 point
then the one after that one, it is:
(D) 14.92 - 0.02x scoring 0 point
then the one after that one, it is:
r = .50

Sara buys 4 candles for $12.25 each.
If she has a coupon for 15% off, and
tax is 8.5%, what is her final bill?
Answer:
$44.98
Step-by-step explanation:
12.25 x 4 = 49
if her coupon is 15% off then she pays 85% of 49, which is 41.65
8% tax added to 41.65 is, 41.65 × .08 = 3.33
total cost is 41.65 + 3.33 = 44.98

A rug like a rectangle has a width of 3 m . The length of the rug is 2 m greater than its widith . What is the perimeter of the rug in meters
Answer:
16m
Step-by-step explanation:
Given data
Width = 3m
Lenght = 2+3= 5m
We know that the expression for perimeter is
P= 2L+2W
Substitute
P= 2*5+ 2*3
P= 10+6
P= 16 m
Hence the perimeter is 16m

Lauren is given a 12% pay rise.Her new salary is £24,080. What was Lauren's salary before the pay rise?
Answer:
The base salary was £21,500.
Step-by-step explanation:
Giving the following information:
Increase rate (g)= 12%
New salary= £24,080
To calculate the base salary, we need to use the following formula:
Base salary= new salary / (1 + increase rate)
Base salary= 24,080 / (1.12)
Base salary= £21,500
The base salary was £21,500.

Answer:
The area is 35 square units.
Step-by-step explanation:
The entire figure is formed by four triangles and a rectangle, whose sum represents the total area ([tex]A_{T}[/tex]), in square units, represented by the following formula:
[tex]A_{T} = A_{1} + A_{2} + A_{3} + A_{4} + A_{5}[/tex] (1)
Where:
[tex]A_{1}[/tex], [tex]A_{2}[/tex], [tex]A_{3}[/tex], [tex]A_{4}[/tex] - Areas of the four triangles.
[tex]A_{5}[/tex] - Area of the rectangle.
By using the area formulas of a triangle and rectangle we expand the equation described above:
[tex]A_{T} = \frac{1}{2}\cdot (3)\cdot (6) + \frac{1}{2}\cdot (3)\cdot (2) + \frac{1}{2}\cdot (2)\cdot (2) + \frac{1}{2}\cdot (3)\cdot (6) + (2)\cdot (6)[/tex]
[tex]A_{T} = 35\,u^{2}[/tex]
The area is 35 square units.

I believe your equation is [tex]y=\frac{4}{5} x-2[/tex]
Step-by-step explanation:
Using the rise over run formula, you get the slope as 4/5. Then, you look for the y-intercept, which turned out to be -2.
Which polar coordinates represent the same point as the rectangular coordinates (-4,5)?
Answer:
2nd option
Step-by-step explanation:
To convert from (x, y ) → (r, θ )
where
r = [tex]\sqrt{x^2+y^2}[/tex]
θ = [tex]tan^{-1}[/tex] ([tex]\frac{y}{x}[/tex] )
Here (x, y ) = (- 4, 5 ), a point in the 2nd quadrant
r = [tex]\sqrt{(-4)^2+5^2}[/tex] = [tex]\sqrt{16+25}[/tex] = [tex]\sqrt{41}[/tex]
θ = [tex]tan^{-1}[/tex] ([tex]\frac{5}{4}[/tex] ) ≈ 51.3° ← related acute angle , then
θ = 180° - 51.3° = 128.7°
Thus
(- 4, 5 ) → ([tex]\sqrt{41}[/tex], 128.7° ) in polar form

Solve for x . Enter the solutions from least to greatest. x^2 + 3x - 4 = 0
Answer:
x^2+(4-1)x-4=0
x^2+4x-x-4=0
x(x+4)-1(x+4)=0
(x-1)(x+4)=0
either (x-1)=0 Or,(x+4)=0
x-1=0
x=0+1
x=1
x+4=0
x=0-4
x=-4
therefore x=-4,1
Step-by-step explanation:
The required solutions for x are x₁= 1 and x₁= -4, and we can write them from least to greatest as -4, 1.
What are the factors?A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.
To solve for x in the quadratic equation x² + 3x - 4 = 0, we can use the quadratic formula:
x = (-b ± √(b² - 4ac)) / 2a
where a, b, and c are the coefficients of the quadratic equation (ax² + bx + c = 0).
In this case, a = 1, b = 3, and c = -4, so we have:
x = (-3 ± √(3² - 4(1)(-4))) / 2(1)
x = (-3 ± √(25)) / 2
x = (-3 ± 5) / 2
x₁ = (-3 + 5) / 2 = 1
x₂ = (-3 - 5) / 2 = -4
Therefore, the solutions for x are x₁= 1 and x₁= -4, and we can write them from least to greatest as -4, 1.

stay safe healthy and happy...To solve the problem "56 is what percent of 70?", Noah uses the double number line below. On the double number line, write the correct numbers at each unlabeled tick mark. Then solve the problem. Explain your answer
Answer:
80%
Step-by-step explanation:
I have filled out and attached the double number line below. From the picture, we can see that the number 56 is 80% of 70. In the image, this is represented by the second number line where 80% is on the same tick as 56 is on the first number line. Mathematically this can be calculated by dividing 56 by 70 and then multiplying that decimal value by 100 to get the percentage like so...
56 / 70 = 0.8
0.8 * 100 = 80%

A video uploaded had 54 upvotes if the ratio of up votes to down votes was 9:8 how many down votes did the video get
Answer:
48
Step-by-step explanation:
Given data
Ratio= 9:8
Combined ratio= 9+8= 17
Upvotes= 54
Let us apply the part to all approach to find the total votes
let the total votes be x
9/17= 54/x
cross multiply
9x= 54*17
9x= 918
divide both sides by 9
x= 918/9
x=102
Hence the number of downvotes is
=102-54
=48
The probability of saving a penalty kick from the opposing team is .617 for a soccer goalie. If 7 penalty kicks are shot at the goal, what is the probability
Answer:
0.2754
Step-by-step explanation:
Probability of saving a penalty kick = 0.617
p = 0.617 ; q = 1 - p = 1 - 0.617 = 0.383
number of trials, n = 7
Number of saves, x = 5
Using the binomial probability relation :
P(x = x) = nCx * p^x * q^(n-x)
P(x = 5) = 7C5 * 0.617^5 * 0.383^2
P(x = 5) = 21 * 0.0894181 * 0.146689
P(x = 5) = 0.2754
