Answer:
The brush cost $5.44, the sketchbook cost 10.88 and the paint set cost 14.50, approximately.Step-by-step explanation:
Givens
Audrian has $35.25The brush was 1/6 as much as the sketchbook.The sketchbook cost 3/4 the cost of the paint set.Audrina had $1.50 leftover.She bough a brush, a sketchbook and a paint set.Based on the given information, we can form the following equations.
[tex]b=\frac{1}{2}s[/tex]
Where [tex]b[/tex] is the brush and [tex]s[/tex] is the sketchbook.
[tex]s=\frac{3}{4}p[/tex]
Where [tex]p[/tex] is paint set.
Now, the sum of all three items would give $1.50 of leftover.
[tex]p+b+s=35.25-1.50[/tex]
Replacing expressions, we have
[tex]p+\frac{1}{2}s+\frac{3}{4}p=30.75\\ \frac{7}{4}p +\frac{1}{2}(\frac{3}{4} p)=30.75\\\frac{7}{4}p+\frac{3}{8}p=30.75\\ \frac{56p+12p}{32}=30.75\\ 68p=984\\p=\frac{984}{68}=14.50[/tex]
Then, we use this value to find the other variables
[tex]s=\frac{3}{4}(14.50)=10.88[/tex]
[tex]b=\frac{1}{2}(10.88)=5.44[/tex]
Therefore, the brush cost $5.44, the sketchbook cost 10.88 and the paint set cost 14.50, approximately.
Answer: paint set costs $18
sketchbook costs $13.5
Brush costs $2.25
Step-by-step explanation:
Let x represent the cost of the paint set.
The sketchbook cost 3/4 the cost of the paint set. It means that the cost of the sketchbook is
3/4 × x = 3x/4
The brush was 1/6 as much as the sketchbook. It means that the cost of the brush is
1/6 × 3x/4 = 3x/24 = x/8
Audrina brought $35.25 to the art supply store. If Audrina had $1.50 leftover after buying these items, it means that the amount spent on the items is
35.25 - 1.5 = 33.75
Therefore,
x + 3x/4 + x/8 = 33.75
Multiplying through by 8, it becomes
8x + 6x + x = 270
15x = 270
x = 270/15
x = 18
The cost of the sketchbook is
(3 × 18)/4 = 13.5
The cost of the brush is
1/8 × 18 = 2.25

Determine if line AB is tangent to the circle.
Answer:
Is a tangent
Step-by-step explanation:
~ By definition, a tangent to circle is a straight line, presently perpendicular to a radius if one. In this case tangent AB should be perpendicular to the radius. If we were to call the center O, we would say AB should be perpendicular to OA. ~
1. Now let us say at the moment that AB is a tangent. If that is so, it should be that m∠A = 90 degrees ( ° ), provided AB is ⊥ to OA by definition.
2. Now the triangle ABO is a right triangle, and with that is should be that Pythagorean Theorem is applied. This can help us prove if AB is a tangent or not. If Pythagorean Theorem is not applicable it would mean ABO is not a right angle triangle, that AB is not ⊥ to OA, and thus can't be a tangent.
3. Let us say x ⇒ side OA, and that side BO = 9 + 8 + 17:
AB^2 + OA^2 = BO^2,
15^2 + x^2 = 17^2,
x = 8
4. Now there are two radii present, OA is only one of them. As radii are ≅, OA = other radii, 8 = 8
5. This proves that Pythagorean Theorem is applicable, that ABO is a right triangle, that m∠A = 90°, and that by definition AB is a tangent

4. The area of the rectangle shown is 200 square units. Find the value of x.
1 point
Your answer
Answer: x = 40
Step-by-step explanation:
Here is the complete question:
The area of the rectangle shown is 200 square units. Find the value of x. Width: 8 Length: 1/2x+5
The area of a rectangle is length multiplied by the width.
Area = Length × Width
Area = 200
Width = 8
Length = 200/8 = 25
Since length is 25 and it has bee denoted as 1/2x + 5. This will be:
1/2x + 5 = 25
1/2x = 25 - 5
1/2x = 20
x = 20 × 2
x = 40
Check:
= 1/2x + 5
= (1/2 × 40) + 5
= 20 + 5
= 25
A prism with a square base has a volume of 96 ft3. The height of the unit is 6 feet. A prism has a length of l, width of 2, and height of 6 feet. Given what you know about the figure, complete these sentences. The area of the square base is feet2. The length of the prism is feet. The width of the prism is feet.
Answer:
The area of the square base is 16 feet the length of the prism is 4 feet, and the width of the prism is 4 feet.
Step-by-step explanation:
The length of the prism is L = 4 feet
What is the volume of a prism?A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.
The volume of a prism is the product of its base area and height
Volume of Prism = B x h
where B = base area of prism
h = height of prism
Given data ,
A square base has a volume of 96 ft3 and a height of 6 feet. Since the volume of a prism is given by the product of the area of the base and the height, we can find the area of the square base as follows:
Volume = area of base x height
96 = area of base x 6
Area of base = 16 ft²
Now, we are given a prism with length of l, width of 2, and height of 6 feet. Since the base is a square, we can set l equal to the width and solve for it using the area of the base we found earlier:
Area of base = l²
16 = l²
l = 4 feet
Hence , the length of the prism is 4 feet and the width is 2 feet

how many times smaller is the surface area of a cube if the side length is multiplied 1/2
Answer:
1/4, or 4 times smaller
Step-by-step explanation:
Since the surface area of a cube is just the combination of the area of all of the square sides, and the formula for those is s^2, if the side length was decreased by 1/2 then the surface area would decrease by (1/2)^2=1/4. Hope this helps!

ABCD is a square with sides of length 9cm. How many points (inside or outside the square) are equidistant from B and from C, and are exactly 6cm from A?
Answer: one point only.
Step-by-step explanation:
Since the length of the sides of the square is 9 cm, taking a point outside the square which is equidistant from point B and C will never give exact 6 cm from A.
The only way to achieve this is by taking a equidistant point inside.
You can achieve exactly 6 cm from point A from point between B and C
But can only achieve a single point if it has to be equidistant from point B and C.

A school wants to have a metal gate placed around it. However they only want to cover three sides of the school and they only have 2000 feet of gate. What are the dimensions of the school if the area is 240,000 square feet?
Answer:
Width = 139.445 ft and Length = 1721.11 ft or
Width = 860.555 ft and Length = 278.89 ft
Step-by-step explanation:
If the school has a rectangular shape, we have that its perimeter and area are:
Perimeter = 2*Length + 2*Width
Area = Length * Width
If we just want to cover 3 sides of the school, we can affirm that:
2000 = Length + 2*Width (eq1)
And the area is 240,000 ft2, so:
240000 = Length * Width (eq2)
From (eq1), we have that:
Length = 2000 - 2*Width
Using this value in (eq2), we have:
240000 = (2000 - 2*Width) * Width
240000 = 2000*Width - 2*Width^2
Width^2 - 1000*Width + 120000 = 0
Using Bhaskara's formula, we have:
Delta = 1000^2 - 120000*4 = 520000
sqrt(Delta) = 721.11
Width1 = (1000 + 721.11)/2 = 860.555 ft
Width2 = (1000 - 721.11)/2 = 139.445 ft
If we use Width = 139.445 ft, we will find Length = 1721.11 ft
If we use Width = 860.555 ft, we will find Length = 278.89 ft
Both pairs of dimensions are valid answers, as they would use 2000 feet of gate and the area of the school would be 240,000 ft2

You can use Pythagoras theorem as it is a right angle
a^2 + b^2 = c^2
where 'c' is the hypotenuse
Rearrange this to find a side length
c^2 - a^2 = b^2
where 'b' is the missing length
10^2 - 8^2 = b^2
100 - 64 = b^2
b^2 = 36
Square root this to get the answer

What is the answer to this question? Write an expression in simplest form for the perimeter of a right triangle with leg lengths of 3a to the third power and 4a to the third power.
Answer:
Step-by-step explanation:
Since the length of both legs of the right angle triangle are given, we would determine the hypotenuse, h by applying Pythagoras theorem which is expressed as
Hypotenuse² = one leg² + other leg²
Therefore,
h² = (3a)³ + (4a)³
h² = 27a³ + 64a³
h² = 91a³
Taking square root of both sides,
h = √91a³
The formula for determining the perimeter of a triangle is expressed as
Perimeter = a + b + c
a, b and c are the side length of the triangle. Therefore, the expression for the perimeter of the right angle triangle is
√91a³ + (3a)³ + (4a)³
= √91a³ + 91a³

You have been tracking how much you spend on gas every month for several months and found that on average you spend about $60 per month. If you had to guess, what would you expect the IQR (Interquartile Range) of your gas spending to be? Would $1, $5 or $100 be most logical? Give statistical reasoning to back up your answer.
Answer: $5
Step-by-step explanation: The interquartile range (IQR) refers to the difference between the upper(75%) quartile and lower(25%) quartile of a distribution. Hence, ensuring that the middle 50% is being captured. With the average given as $60, having a interquartile range capturing the middle 50% as $1 seems so small from a statistical stand point. Similarly, an interquartile range of $100 capturing the middle 50% is also too large and nearly impossible if the average price is $60. However, a price of $5 sit well in between considering the average price of $60

find the two smallest possible solutions to part 1a
============================
Work Shown:
12*sin(2pi/5*x)+10 = 16
12*sin(2pi/5*x) = 16-10
12*sin(2pi/5*x) = 6
sin(2pi/5*x) = 6/12
sin(2pi/5*x) = 0.5
2pi/5*x = arcsin(0.5)
2pi/5*x = pi/6+2pi*n or 2pi/5*x = 5pi/6+2pi*n
2/5*x = 1/6+2*n or 2/5*x = 5/6+2*n
x = (5/2)*(1/6+2*n) or x = (5/2)*(5/6+2*n)
x = 5/12+5n or x = 25/12+5n
these equations form the set of all solutions. The n is any integer.
--------
The two smallest positive solutions occur when n = 0, so,
x = 5/12+5n or x = 25/12+5n
x = 5/12+5*0 or x = 25/12+5*0
x = 5/12 or x = 25/12
--------
Plugging either x value into the expression 12*sin(2pi/5*x)+10 should yield 16, which would confirm the two answers.
Answer:

Step-by-step explanation:
12sin(⅖pi x) + 10 = 16
sin(⅖pi x) = 6/12

⅖pi x = pi/6, pi - pi/6
⅖pi x = pi/6, 5pi/6
x = 5/12, 25/12
