Answer:
The distance between the top two buttons on his shirt is 3.8 inches.
Step-by-step explanation:
Maurice's shirt has 5 buttons. Distance between first and last button is 15.25.
If we see, they would be arranged like
*
*
*
*
*
They are equally spaced between each button.
So, there are 4 equal spaces between the buttons.
Distance between each two consecutive buttons =[tex]\frac{15.25}{4}[/tex] =3.8125
So, distance between the top two buttons on his shirt is 3.8 inches.

A basketball hoop has a
diameter of approximately
18 inches. What is the
circumference of the
basketball hoop?
The perimeter of the basketball hoop is 18π inches.
The circumference of a circle can be found using the formula:
C = πd
where C is the circumference and d is the diameter of the circle.
In this case, the diameter of the basketball hoop is approximately 18 inches. So we can plug this value into the formula to get:
C = π(18)
Using a calculator or approximating π to 3.14, we can evaluate this expression to get:
C ≈ 56.52 inches
Therefore, the circumference of the basketball hoop is approximately 56.52 inches.

5 pencils and 3 pens costs £11.
4 pencils and 6 pens costs £16.
Find the cost of a pencil.
Find the cost of a pen.
Answer:
The pencil is £1 and the pen is £2
Step-by-step explanation:
Let the pencil be p and let the pen be f.
5p + 3f = 11
4p + 6f = 16
the top one multiplies by two:
10p + 6f = 22
4p + 6f = 16 subtract
6p = £6
pencil = £1
Then you substitute the value of the pencil into the equation and find the value of the pen.

2. The floor plan for a rectangular building states that the length of the building is to be 8 meters more than 3 times its width . If the floor area is to be 256 square meters, what must be the length and width of the building?
Area of a rectangle = Length × Width
Length of the building is to be 8 meters more than times its width.
= Length = 3W + 8
Area = 256m²
Hence:
256 =( 3W + 8 )× W
256 = 3W² + 8W
= 3W² + 8W - 256
Factorise
= 3W(W - 8) + 32(W - 8)
= (3W + 32) ( W - 8)
W - 8 = 0
W = Width = 8m
Length = 3W + 8
Length = 3(8) + 8
= 24 + 8
= 32m.
D. 32 meters long and 8 meters wide
3. The area of the dining room is 130 square units. If the width is 3 meter less than its length what is the width
of the room?
A. 10 units
B. 11 units
C 12 units
D. 13 units
Area = Length × Width
The width is 3 meter less than its length
W = L - 3
Area = 130 square units
Hence:
130 = L (L - 3)
130 = L² - 3L
L² - 3L - 130
= L² + 10L - 13L - 130
= L(L + 10) - 13(L + 10)
= (L - 13) (L + 10)
L - 13 = 0
L = Length = 13 units
L + 10 = 0
L = -10 units.
W = L - 3
L = 13 units
W = 13 - 3
W = 10 units
Therefore, the width of the room is 10 units
A. 10 units
4. One of the factors of 2b² + 15b-50 is b + 10. What is the other factor?
A.2b - 10
B. 2b -5
C. 2b +5
D. 2b + 10
2b² + 15b -50
One of the factors is b +10.
We factorise
2b² + 15b - 50
= 2b² + 20b - 5b - 50
= 2b(b + 10) - 5(b + 10)
= (2b - 5) (b + 10)
The other factor is 2b - 5
B. 2b -5
5. The area of the nachos is 15x² - 10x square centimeters. If the base is 5x centimeters, which is the length of

Nachos are triangular in shape
Area of a triangle = 1/2 × Base × height
A = 1/2 bh
A = bh/2
2A = bh
h = 2A/b
The area of the nachos is 15x - 10x square centimeters. If the base is 5x centimeters,
h = 2(15x² - 10x)/5x
h = 30x² - 20x/5x
h = 30x²/5x - 20x/5x
= 6x - 4 cm
the length of the height is:
C. 6x - 4 cm

Some number minus 11 is equal to the product of the number and 18.
Answer:
n - 11 = 18n
Step-by-step explanation:
n−11=18n
Step 1: Subtract 18n from both sides.
n−11−18n=18n−18n
−17n−11=0
Step 2: Add 11 to both sides.
−17n−11+11=0+11
−17n=11
Step 3: Divide both sides by -17.
−17n−17=11−17
n=−1117
Answer:
n = −11/17

Answer:
x = 60
Step-by-step explanation:
In order to make L parallel (||) to M, you want to prove that the angles are same-side interior angles since the Same-Side Interior Angle Theorem only works for parallel lines cut by a transversal.
In order to make the angles (marked with the expressions) same-side interior angles, they have to add up to 180 degrees because they are supplementary angles.
Make an equation where the two angles add up to (equal) 180.
(x - 5) + (2x + 5) = 180Combine like terms on the left side of the equation.
3x = 180Divide both sides of the equation by 3.
x = 6060 is the value of x that will make L || M.

The perimeter of the rectangle below is 54 units. Find the value of x
Answer: x=5
Step-by-step explanation:
3x appears two times and so does 2x +2. That created the equation 3x + 3x + 2x + 2 + 2x + 2=54. Combine like terms. You get 10x +4=54. Then you solve. Inverse operation: You subtract 4 from 54. Which is 50, then divide by 10. X=5
The value of the x for the given rectangle is 5 units.
What is the perimeter of a rectangle?The whole distance that a rectangle's boundaries, or its sides, the cover is known as its perimeter. Given that a rectangle has four sides, the perimeter of the rectangle will be equal to the sum of its four sides.
Given, The perimeter of the rectangle below is 54 units.
Also given the length of the rectangle = 3x
and the width of rectangle = 2x + 2
Since, Perimeter of rectangle = 2 *( length + width)
Perimeter of rectangle = 2 * (3x + 2x + 2)
Since we have a perimeter
54 = 2 *(5 x + 2)
5x + 2 = 27
5x = 25
x = 5
Therefore, For the given rectangle, the value of x is 5 units.
