there are 9 15's in 120 which means its going by 15's 3 x 5= 15 and if it says 6 that means its timesed by 2. 15 x 2= 30 then 30 x 10= 300
This net consists of a square and 4 identical triangles. What is the surface area of the solid this net can form?
144 square inches
184 square inches
224 square inches
264 square inches
Answer: C, 224 inches squared
Step-by-step explanation:
When formed into a solid, the triangles are folded upwards to make a pyramid. You can find the surface area by finding the areas of the individual shapes.
There are four triangles with a height of 10 inches and a base of 8 inches.
There is one square with a side length of 8 inches.
Triangle area formula : A = (b * h) / 2
Square area formula: A = s^2
(10 * 8) / 2 = 40
8 ^ 2 = 64
There are four triangles with area of 40 and one square with area of 64.
40 + 40 + 40 + 40 + 64 = 224 inches squared. The correct answer choice is C.
The surface area of the pyramid is 224 in².
What is surface area?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Given net will form a square pyramid, so we will find the surface area of the square pyramid.
Therefore,
The area of the pyramid = side² + 2 × side × height
= 8² + 2 × 8 × 10
= 64 + 160
= 224
Hence the surface area of the pyramid is 224 in².

Suppose you have a rectangle with a perimeter of 2 cm. What can you conclude about the side lengths? Can all 4 sides of the rectangle measure a whole number of centimeters?
Answer:
Step-by-step explanation:
The formula for a perimeter of a rectangle = 2(L+B)
= 2L+2B
Where L and B are length and breadth respectively.
The question says ;
2cm = 2(L+B)
2cm = 2L+2B
Divide both sides by 2
1 = L+B
If the sum of the length and breadth is equivalent to 1cm, then the length itself is less than 1 cm. That is L < 1 cm
When all sides of the rectangle is summed, it will definitely be a whole number since the perimeter is 2 cm

Using Letter A, as example:
To calculate the distance between the points, you use the formula:
[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]d = \sqrt{(2-2)^2+(10-4)^2}[/tex]

Your friend buys a skateboard that is on sale for one third off the original price. Your friend spent $36 than the original price. What was the original price of the skateboard?
Answer:
original price of skateboard = $54
Step-by-step explanation:
Let the original price of the skateboard be x
selling price = one third off the original price = $36
x - (1/3x) = 36
[tex]\frac{x}{1} - \frac{x}{3} = \frac{3x-x}{3} = \frac{2x}{3}[/tex]
[tex]\frac{2x}{3} = 36\\2x = 108\\x = \frac{108}{2} = 54[/tex]
∴ x = 54

Luke is designing a scale model of a clock tower. The design of the front of the tower is shown below. What will be the area of the front face of his model? 2,500 square millimeters 10,000 square millimeters 12,500 square millimeters 15,000 square millimeters
The image of the front of the tower is missing, so i have attached it.
Answer:
Option B - 10,000 square millimeters
Step-by-step explanation:
From the image attached, we see that the dimensions of the front of the tower are;
Length; L = 200 mm
Width; w = 50 mm
Now, this front face takes the shape of a rectangle.
Area of rectangle = Length x width
Thus, plugging in the values of length and width, we will get;
Area of front face = 200 x 50
Area of front face = 10,000 square millimeters
Answer:
12,500 mm^2
Step-by-step explanation:
50 x 200 = 10,000 mm
(300 - 200 = 100) 100 x 50 x 1/2 = 2,500 mm
10,000 + 2,500 = 12,500 mm^2

Solve the quadratic equation by completing the square. What are the missing pieces to the steps?
-27 = 4x²- 24x
-27 = 4(x²- 6x + 9)
9 =4(x²- 6x + 9)
9/4 = (x -3)
+__= x - 3
__ = x
Answer:
The missing pieces should be after line 3.
9/4 = (x - 3)^2
<=> (3/2)^2 = (x - 3)^2
<=> x - 3 = 3/2 or x - 3 = -3/2
<=> x = 3 + 3/2 or x = 3 - 3/2
<=> x = 9/2 or x = 3/2

[tex]\frac{3}{2}=x-3[/tex]
and
[tex]\frac{9}{2}=x[/tex]
Step-by-step explanation:
[tex]-27=4x^2-24x[/tex]
First, factor 4 to make isolate [tex]x^2[/tex]
[tex]-27=4(x^2-6x)[/tex]
Now, divide by 4.
[tex]-\frac{27}{4}=x^2-6x[/tex]
Complete the square by adding [tex](\frac{b}{2})^2[/tex]
[tex](\frac{b}{2})^2-\frac{27}{4}=x^2-6x+ (\frac{b}{2})^2[/tex]
[tex](\frac{6}{2})^2-\frac{27}{4}=x^2-6x+ (\frac{6}{2})^2[/tex]
[tex](3)^2-\frac{27}{4}=x^2-6x+ (3)^2[/tex]
[tex]9-\frac{27}{4}=x^2-6x+9[/tex]
Solve the difference.
[tex]\frac{9*4-27}{4}=x^2-6x+9[/tex]
[tex]\frac{36-27}{4}=x^2-6x+9 \\\frac{9}{4}=x^2-6x+9[/tex]
Factor the equation.
[tex]\frac{9}{4}=(x-3)(x-3)[/tex]
Rewrite it;
[tex]\frac{9}{4}=(x-3)^2[/tex]
Extract the square root.
[tex]\sqrt{\frac{9}{4} }=x-3[/tex]
Take the square root of 9 and 4.
[tex]\frac{3}{2}=x-3[/tex]
Add 3.
[tex]\frac{3}{2}+3=x[/tex]
Do the sum
[tex]\frac{3+2*3}{2}=x\\\frac{3+6}{2}=x\\\frac{9}{2}=x[/tex]

Unit 6. 2) Please help. What is the probability that a student is absent given that today is Monday?
Enter your answer as a fraction in simplest form, formatted like this: 3/14
Answer:
Let's denote:
The probability that today is Monday: P(A)
The probability that a student is absent: P(B)
The probability that a student is absent given that day is Monday: P(B|A)
As given,
P(A intersect B) = 3/100
P(A) = 1/5
=> P(B|A) x P(A) = P(A intersect B)
=> P(B|A) = P(A intersect B)/P(A) = (3/100)/(1/5) = 15/100 = 3/20
Hope this helps!

Stefan bought 2 turkey sandwiches and 5 ham sandwiches for a total cost of $40.50. Nancy bought 4 turkey sandwiches and 1 ham sandwich for a total cost of $31.50. The equations below represent Stefan's and Nancy's purchases.
Answer:
Price of each turkey sandwich = $6.5
price of each ham sandwich = $5.5
2a + 5b = 40.50.........(i)
4a + b = 31.50..............(ii)
Step-by-step explanation:
Let
price of each turkey sandwich = a
price of each ham sandwich = b
Stefan purchase
2a + 5b = 40.50.........(i)
Nancy purchase
4a + b = 31.50..............(ii)
combine the equations
2a + 5b = 40.50.........(i)
4a + b = 31.50..............(ii)
b = 31.50 - 4a
insert the value of b in equation(i)
2a + 5b = 40.50.........(i)
2a + 5(31.50 - 4a) = 40.50
2a + 157.5 - 20a = 40.50
-18a = 40.50 - 157.5
-18a = -117
divide both sides by -18
a = -117/-18
a = 6.5
insert the value of a in equation(ii)
4a + b = 31.50..............(ii)
4(6.5) + b = 31.50
26 + b = 31.50
b = 31.50 - 26
b = 5.5
Price of turkey sandwich = $6.5
price of ham sandwich = $5.5
