Answer:
56.9°
Step-by-step explanation:
Assuming you mean a and b as the legs of a right triangle and θ as the bigger angle in a right triangle, we can work out easily that
cos θ = 6/11
so θ ≈ 56.9°(to 1 d.p.)

Answer:
4 dollars per pair of socks.
Step-by-step explanation:
You already determined that x and y have a proportional relationship, as y is four times the x value. Therefore, when x is 1, that means one pair of socks will be four dollars.
Another way to solve this is by forming a linear equation.
y = 4x
Any number plugged into x to represent pairs of socks will give the cost, y.
For example: y = 4(7), which simplifies to y = 28.
This means that for every one pair of socks, it costs four dollars.
Answer:
yes and $4
Step-by-step explanation:
7*4=28
11*4=44
13*4=52
15*4=60

Write a polynomial in standard form that represents the area of the shaded region.
Answer:
[tex]A=p^2-2p-3[/tex]
Step-by-step explanation:
The area for a triangle is given by:
[tex]\displaystyle A=\frac{1}{2}bh[/tex]
The base is p + 1 and the height is 2p - 6. Therefore:
[tex]\displaystyle A=\frac{1}{2}(p+1)(2p-6)[/tex]
Simplify the second term:
[tex]\displaystyle A=(p+1)(\frac{1}{2})(2p-6)=(p+1)(p-3)[/tex]
Distribute:
[tex]A=p(p-3)+1(p-3)[/tex]
Distribute:
[tex]A=p^2-3p+p-3[/tex]
Combine like terms:
[tex]A=p^2-2p-3[/tex]
Use the FOIL Method to find (w+9)(w+6)

Step-by-step explanation:
First, outside, inside, last.
w*w
6*w
9*w
9*6
[tex]w^2+15w+54[/tex]
Answer: w^2 + 15w + 54
Step-by-step explanation:
FOIL = first, outside, inside, last.
First —> multiply first numbers of each parentheses.
Outside —> multiple the OUTSIDE numbers in each parentheses (first number in the first parentheses, second number in the second parentheses.
Inside —> multiply the INSIDE numbers in each parentheses (the second number in the first parentheses, first number in the second parentheses).
Last —> multiply second number of each parentheses.
(W + 9)(w + 6)
F = w^2
O = 6w
I = 9w
L = 54
W^2 + 6w + 9w + 54
W^2 +15w + 54

Caroline uses 9.1 pints of blue paint and white paint to paint her bedroom walls. 1 4 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answer:
6.83 pints
Step-by-step explanation:
The first step is to calculate the volume of the blue paint
= 9.1 × 1/4
= 2.275
Therefore the volume of the white paint can be calculated as follows
= 9.1 - 2.275
= 6.83
Hence the volume of white paint that Caroline used to paint her bedroom walls is 6.83 pints
verify that 1,-1,-3 are the zeroes of the cubic polynomial x3+3x2-x-3 and check the relationship between zeroes and the coefficient
Answer: yea its 123445
Step-by-step explanation:
1,-1,-3 are the zeroes and the relationship between zeroes and the coefficient is verified.
What is a Polynomial?Polynomial, a mathematical expression made comprised of numbers and variables arranged in specific patterns.
As per the given data:
We are given the equation of a cubic polynomial x³ + 3x² - x - 3.
The zeroes of the given cubic polynomial are also given.
We have to verify that the zeroes of the cubic polynomial are correct, and they satisfy the relationship between zeroes and the coefficient.
For a polynomial p(x) is p(a) = 0 then a is a zero of p(x).
Checking the given zeroes similarly:
For 1:
1³ + 3(1)² - 1 - 3 = 0
1 + 3 - 1 - 3 = 0
0 = 0
1 is a zero
For -1:
(-1)³ + 3(-1)² - (-1) - 3 = 0
-1 + 3 + 1 - 3 = 0
0 = 0
-1 is a zero
For -3:
(-3)³ + 3(-3)² - (-3) - 3 = 0
-27 + 27 + 3 - 3 = 0
0 = 0
-3 is a zero
For ax³ + bx² + cx + d = 0, the sum of all the roots should be equal to
= (-b)/a
Similarly, for x³ + 3x² - x - 3:
1 + (-1) + (-3) = (-3)/1
1 - 1 - 3 = -3
-3 = -3
1,-1,-3 are the zeroes and the relationship between zeroes and the coefficient is verified.
Hence, 1,-1,-3 are the zeroes and the relationship between zeroes and the coefficient is verified.

1. Let the side length of each small square on the grid represent 1 unit. Draw two different triangles, e. Ach with base 5 1/2 units and area 19 1/4 units2. 2. Why does each of your triangles have area 1914 units2?
Answer:
Step-by-step explanation:
Given that:
Each small square on a grid represents 1 unit
Base of triangle = 5 1/2 units = 11/2
Area of triangle = 19 1/4 unit² = 77/4
The Area, A of a triangle is obtained thus :
77/4 = 1/2 * 11/2 * h
77/4 = 11/4 * h
h = 77/4 ÷ 11/4
h = 77/4 * 4 /11
h = 7 units

In how many ways can you answer a 13-question true-false test if you answer each question with either a "true" or a "false"?
Answer:
[tex]\frac{1}{1892}[/tex]
Step-by-step explanation:
There are two possibilities for each of 13 questions, true or false. As a result, you have a [tex]\frac{1}{2}[/tex] chance of choosing either of the choices. To find this, you would multiply the probability to the power of the number of cases, meaning [tex](\frac{1}{2^(13)})=\frac{1}{1892}[/tex].

Addison and Bert are in the same reading group at school. The book they're reading right now is 256 pages long. Addison has read 102 pages so far and decides to read 16 pages every day until she finishes the book. Bert has read 142 pages, and he plans to read 11 pages every day. How many days will it be until Addison and Bert have each read the same number of pages in total? How many pages will they each have read?
Answer: The answer in this photo thanks for a little quiz
The number of day it will be until Addison and Bert each have read the same number of pages in total is 8 days.
What is an equation?In mathematics, an equation is a statement of equality between two expressions, indicated by the equals sign (=). Solutions to equations are the values for unknowns which, when substituted into the expression, make it true.
Given that, the book they're reading right now is 256 pages long.
Let the number of days be x.
Addison has read 102 pages so far and decides to read 16 pages every day until she finishes the book.
102+16x -------(i)
Bert has read 142 pages, and he plans to read 11 pages every day.
142+11x -------(ii)
Addison and Bert have each read the same number of pages in total.
So, (i)=(ii)
102+16x=142+11x
16x-11x=142-102
5x=40
x=8
Hence, the number of day it will be until Addison and Bert each have read the same number of pages in total is 8 days.

Ali receives a 4% commission for all his sales. His sales for January were $15,000. What was the commission amount he earned for the month of January?
Answer:
$600
Step-by-step explanation:
Convert the 4% commission into a decimal, which is 0.04.Multiply the sales ($15,000) by the commission as a decimal (0.04). This is $600, which is the answer.Max and jane had $84 altogether. Max had $6 less than jane. Use algebra to find the amount of money jane had
Answer:
Jane has $45, and Max has $39.
Step-by-step explanation:
M + J = 84
M = J-6
( J - 6 ) + J = 84
2J - 6 = 84
2J = 90
J = $45
M= $39
