Total boxes = 9
Total scarves in each box = s
ATQ
9s+(-9) = 36
9s -9 = 36
9s = 36+9
9s = 45
s = 45/9
s = 5
Value of s is 5
Must click thanks and mark brainliest
Answer:
s = 5
Step-by-step explanation:
9* number of scarves in each box after removing 1 scarf = 36
9 *(s -1) = 36
9s - 9 = 36 {Distributive property}
9s = 36+ 9 {add 9 to both sides}
9s = 45
s= 45/9 {Divide both sides by 9}
s = 5

Eight years ago, the daughters age was thrice the son's age. Now the daughter's age is 4 years more than the son's age. Find their present ages.
Answers
Answer:
Let s be the son’s current age and d be the daughter’s current age. The system of equations is:
s - 10 = 2(d - 10)
s = 3 + d
Since s is already set to an equation, we can use the substitution method for s in the other equation:
s = 3 + d
s - 10 = 2(d - 10)
3 + d - 10 = 2(d - 10)
Simplify and solve for d:
3 + d - 10 = 2(d - 10)
-7 + d = 2d - 20
-7 = d - 20
13 = d
The daughter is 13 years old. To solve for the son’s age, we will plug in the solution for d into one of the equations. The second one is simpler so we will use that:
s = 3 + d
s = 3 + 13
s = 16
The son is 16 years old. Let us use the other equation to check our solutions:
s - 10 = 2(d - 10)
16 - 10 = 2(13 - 10)
6 = 2(3)
6 = 6
It checks out. The son is 16 years old, and the daughter is 13 years old.
The present age of the daughter and son are 14 and 10 years respectively.
Let the age of the daughter be x
Let the age of the son be y
If the daughter's age is 4 years more than the son's age now, then,
x = y + 4 ............. 1
If Eight years ago, the daughters' age was thrice the son's age, then;
Daughter = x - 8
Son = y - 8
Hence, x - 8 =3(y - 8).................. 2
Substitute equation 1 into 2 to have:
x - 8 =3(y - 8).
y + 4 - 8 = 3(y - 8)
y - 4 = 3y - 24
y - 3y = -20
-2y = -20
y = 10
Recall that x = y + 4
x = 10 + 4
x = 14
Hence the present age of the daughter and son are 14 and 10 years respectively.

CINDY BOUGHT A 12.3 POUND TURKEY AND AN 11.7 POUND HAM FOR HOLIDAY DINNER AND PAID $34.68. Her friend Samantha bought a 10.7 pound turkey and 9.5 pound ham for $29.05. What is the cost per pound of turkey and the cot per pound of ham
Answers
Answer:
Cost of Turkey per pound is $ 1.25 and Ham is $ 1.65.
Step-by-step explanation:
Cindy:
cost of 12.3 pound Turkey and 11.7 pound Ham = $ 34.68
Samantha:
cost of 10.7 pound Turkey and 9.5 pound Ham = $ 29.05
Let the cost of one pound of Turkey is T and one pound of Ham is H.
So,
12.3 T + 11.7 H = 34.68 ..... (1)
10.7 T + 9.5 H = 29.05 ......(2)
Solve both these equations, we get
T = $ 1.25 and H = $ 1.65

Answer:
(7, 13/3)
Step-by-step explanation:
Given the expressions
y = 1/3x + 2 and the second line y = 4/3x - 5
Equating both expressions
1/3x + 2 = 4/3x - 5
1/3x - 4/3x = -5 - 2
-3/3x = -7
-x = -7
x = 7
Substitute x = 7 into any of the equations
Using y = 1/3 x + 2
y = 1/3(7) + 2
y = 7/3 + 2
y = (7+6)/3
y = 13/3
Hence the solution to the system of the equation is (7, 13/3)

doing square root on both side we get

Similarly
[tex]Sin\theta_{1}=\sqrt{1-Cos²\theta_{1}}[/tex]

[tex]\bold{Sin\theta_{1}=-\frac{4}{5}}[/tex]
Answer:
[tex]\sin(\theta_1)=-\frac{4}{5}[/tex]
Step-by-step explanation:
We'll use the Pythagorean Identity [tex]\cos^2(\theta)+\sin^2(\theta)=1[/tex] to solve this problem.
Subtract [tex]\cos^2(\theta)[/tex] from both sides to isolate [tex]\sin^2(\theta)[/tex]:
[tex]\sin^2(\theta)=1-\cos^2(\theta)[/tex]
Substitute [tex]\cos(\theta)=\frac{3}{5}[/tex] as given in the problem:
[tex]\sin^2(\theta_1)=1-(\frac{3}{5}^2)[/tex]
Simplify:
[tex]\sin^2\theta_1=1-\frac{9}{25}[/tex]
Combine like terms:
[tex]\sin^2\theta_1=\frac{16}{25}[/tex]
For [tex]a^2=b[/tex], we have two solutions [tex]a=\pm \sqrt{b}[/tex]:
[tex]\sin\theta_1=\pm \sqrt{\frac{16}{25}},\\\begin{cases}\sin \theta_1=\frac{4}{5},\\\sin \theta_1=\boxed{-\frac{4}{5}}\end{cases}[/tex]
Since the sine of all angles in quadrant four return a negative output, [tex]\frac{4}{5}[/tex] is extraneous and our answer is [tex]\boxed{\sin(\theta_1)=-\frac{4}{5}}[/tex]
sin pi/3 __ __ pi/6 = 1/2(sin pi/2 + sin pi/6)
I think I’m just supposed to fill in the blank? (question off of a p e x) please give explanation!
Answers
Notice that
• π/2 = π/3 + π/6
• π/6 = π/3 - π/6
Recall the angle sum identities for sine:
sin(x + y) = sin(x) cos(y) + cos(x) sin(y)
sin(x - y) = sin(x) cos(y) - cos(x) sin(y)
By adding these together, we get
sin(x + y) + sin(x - y) = 2 sin(x) cos(y)
==> sin(x) cos(y) = 1/2 (sin(x + y) + sin(x - y))
Now take x = π/3 and y = π/6 :
sin(π/3) cos(π/6) = 1/2 (sin(π/2) + sin(π/6))
So the blank should be filled with cos.
Plans for a new shopping center call for buildings directly across the sidewalk from each other to be congruent. This computer printout shows a clothing store.
If the vertices of a home improvement store are located at (−x1,y1), (−x2,y2), (−x3,y3), and (−x4,y4), will the home improvement store be congruent to the clothing store?
Answers
Answer:
Yes, both stores will be congruent
Step-by-step explanation:
The given coordinates of the vertices of the home improvement store are;
(-x₁, y₁), (-x₂, y₂), (-x₃, y₃) and (-x₄, y₄)
The coordinates of the vertices of the clothing store are;
(x₁, y₁), (x₂, y₂), (x₃, y₃) and (x₄, y₄)
Therefore, the coordinates of the vertices of the home improvement store, corresponds to the coordinates of the vertices of the image of the reflection of the clothing store across the sidewalk (which is the y-axis)
A reflection of (x, y) across the y-axis gives (-x, y)
Given that a reflection is a rigid transformation, the dimensions (lengths and angles between corresponding sides) of the home improvement store and the clothing store are equal, therefore, the home improvement store will be congruent to the clothing store.
Answer: yes, because the home improvement store is a reflection of the clothing store.

Answer:

Step-by-step explanation:
The given equation of the function is y = -a·(x - h)² + 1
The positive constants of the equation = a, and h
The points the function crosses the x-axis = 2, and 4
Where the function crosses the x-axis, y = 0, and x = 2, and 4, therefore, when x = 2, we have;
y = 0 = -a·(2 - h)² + 1
When x = 4, we have;
0 = -a·(4 - h)² + 1
-a·(2 - h)² + 1 = -a·(4 - h)² + 1
-a·(2 - h)² = -a·(4 - h)²
(2 - h)² = (4 - h)²
±(2 - h) = +#±(4 - h)
When
(2 - h) is negative, and (4 - h) is positive, but the same magnitude, we have';
-(2 - h) = +(4 - h)
2·h = 4 + 2 = 6
h = 3
0 = -a·(4 - h)² + 1 = -a·(4 - 3)² + 1 = -a + 1
Therefore, a = 1
Describe the process you would use to explain to your parents (or other significant adults in your life) how you could calculate the sum of the interior angles of a 12-sided object without measuring them.
Use a word processor, to write up the process you have developed.
Answers
The sum of the interior angles of the 12-sided object without measuring the sides is 1800 degrees.
A polygon is a shape with 4 or more sides. Hence a 12-sided figure will be regarded as a polygon.
I will let them understand that the formula for calculating the sum of the interior angle of a regular polygon is expressed using the formula;
S = (n-2)*180 where:
n is the number of sides
Since we are considering a 12-sided object, then n = 12
The next thing is to tell them to substitute n = 12 into the formula given above as shown;
S = (12-2)*180
S = 10 * 180
S = 1800
This shows that the sum of the interior angles of the 12-sided object without measuring the sides is 1800 degrees.

|-4x-6| = 14
There are two solutions, one positive and one negative
-4x-6 = 14 -4x-6 = -14
Add 6 to each side
-4x-6+6 = 14+6 -4x-6+6 = -14+6
-4x = 20 -4x = -8
Divide by -4
-4x/-4 = 20/-4 -4x/-4 = -8/-4
x = -5 x = 2
Now we have to,
find the required value of x.
Given that,
→ |-4x -6| = 14
Let's find the both positive value and negative value,
===================
→ -4x -6 = 14
→ -4x = 14 + 6
→ -4x = 20
→ x = 20/-4
→ [x = -5]
===================
→ -4x -6 = -14
→ -4x = -14 + 6
→ -4x = -8
→ x = -8/-4
→ x = 8/4
→ [x = 2]
===================
Therefore, x is -5 (or) 2 is the answer.
