Answer:
2.25 cm³
Step-by-step explanation:
The volume of a pyramid can be found using the formula:
[tex] \boxed{\text{volume of pyramid= ⅓×base ×height}}[/tex]
Base area
= area of square
= side ×side
= 1.5²
= 2.25 cm²
Volume of paperweight
= ⅓(2.25)(3)
= 2.25 cm³

A rucksack can hold a maximum of 3 kg.
A particular textbook has a mass of 650 g.
What is the maximum number of these textbooks that the rucksack can hold?
Reason:
x = number of textbooks
650x = weight of all x books, at 650 grams each
3 kg = 3000 g
650x = 3000
x = 3000/650
x = 4.615 approximately
Round down to the nearest integer. This is because 4 textbooks weigh 4*650 = 2600 grams = 2.6 kg; while 5 textbooks weigh 5*650 = 3250 grams = 3.25 kg which is over the weight limit.
This means 4 books is the most the rucksack can hold. This is of course only when we have 4 of the same exact book.
Trey made a scale drawing of a microchip using s scale of 2 inches to 1 centimeter. His drawing was an enlargement that depicted the chip as 6inches long and 4 inches wide. However, the drawing isnt big enough to clearly show all of the chips components. So he wants to make the drawing bigger. Complete the steos below to figure the dimensions if trey changes the scale to 3 inches to 1 centimeter.
A) What is the actual length of the microship?
B) What is the actual width of the microchip?
C) Trey wants to change the scale of the drawing to 3in to 1cm. Use the actual length from part A to find the length of the microchip in treys new scale drawing.
D) Use the actual width from part B to find the width of the microchip in treys new scale drawing.
E) what is the ratio of a drawing measurement from the original scale to the corresponding drawing measurement in the new scale?
Answer:
A) The actual length of the microchip is 3 centimeters.
B) The actual width of the microchip is 2 centimeters
C) The ratio of the original scale drawing measurements to the new scale drawing measurements is 2 inches to 3 inches.
Step-by-step explanation:
A) actual length = scale length × reciprocal of scale factor
The scale is 2 inches to 1 centimeter, so the scale factor is. 2in/1cm The reciprocal of the scale factor is. 1cm/2in The length of the chip in the scale drawing is 6 inches.
= 6 in. x (1cm/2in)
= 3 cm
B) actual width = scale width × reciprocal of scale factor
= 4 in. x (1cm/2in)
= 2 cm
C) The original scale drawing, the microchip was 6 inches long. It is now 9 inches long.
Ratio: 6in/9 in 3in/2in
The microchip was 4 inches wide. In the new scale drawing, the microchip is 6 inches wide.
Ratio: 4in/6in 2in/3in

Amaya is graphing the inequality x>11 on a number line. Which statements below describe steps she may take to graph the inequality correctly? Check all that apply.
Draw an open circle at 11.
Draw a closed circle at 12.
Shade all numbers to the left of 11.
Shade all numbers to the left of 12.
Shade all numbers to the right of 11.
Shade all numbers to the right of 12.
Answer:
Draw an open circle at 11.
Shade all numbers to the right of 11.
Step-by-step explanation:
If you have an inequality that has a < or a > symbol, then your circle is open.
Because x is greater than 11, you would shade the numbers greater than 11, or to the right of 11.
Answer:
Draw an open circle at 11.
Shade all numbers to the right of 11.
Step-by-step explanation:
she draws an open circle because the "greater than" sign is not "greater than or equal" if it is the sign "greater than or equal" the circle should be a closed circle.
And she shades all numbers to the right of 11 because "x" is greater than 11 and she shades the side that is positive, not negative.

write an equation using x and y to represent the hanger.
Answer:
Step-by-step explanation:
Givens
The triangle is x
The square is y
Left side
x + 3y is the weight
Right side
4x + y is the weight.
The weights are equal because the hanger is balanced.
Balance equation
x + 3y = 4x + y Subtract x from both sides
x-x + 3y = 4x-x + y Combine
3y = 3x + y Subtract y from both sides
3y - y = 3x + y - y Combine
2y = 3x
Answer
2y = 3x
Answer:
x +3y = 4x +y
Step-by-step explanation:
A hanger diagram like this is intended to show you that the total weight on the left side is equal to the total weight on the right side.
__
left sideThe left side shows 1 triangle and 3 squares. x and y are defined as the weights of the triangle and square, respectively, so the weight on the left side can be represented as ...
x + 3y
right sideThe four triangles and 1 square on the right can have their total weight represented as ...
4x +y
balanceThe intent of the diagram is to show that the left-side weight is equal to the right-side weight. That equality can be written as ...
x +3y = 4x +y
_____
Additional comment
This problem is not asking for any sort of "solution" or relationship between x and y. We could find such a relationship by solving the equation for y:
x +2y = 4x . . . . subtract y from both sides
2y = 3x . . . . . . . subtract x from both sides
y = (3/2)x . . . . . divide by the coefficient of y
This tells you that the hanger will only be balanced if the weight of a square is half-again as much as the weight of a triangle.

What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
A rucksack can hold a maximum of 3 kg.
A particular textbook has a mass of 650 g.
Hence, We get;
⇒ 3 kg = 3000 g
Thus, the maximum number of these textbooks that the rucksack can hold is,
⇒ 3000 ÷ 650
⇒ 4.61
Thus, the maximum number of these textbooks that the rucksack can hold is, 4

"The area of the base of a rectangular prism is 12 cm2, and the height is 3 1/3cm. Determine the volume of the rectangular prism."
please helppppppp
Answer:
Given The base of a rectangular prism has an area of 12 sq cm. The height of the rectangular prism is 3 cm
Now volume of the rectangular prism is given by length x width x height
Also area of rectangular prism is 12 sq cm and height of the rectangular prism is 3 cm.
But area of rectangle is length x width
Now volume of the rectangular prism V = 12 cm^2 x 3 cm V = 36 cm^3Therefore volume of the rectangular prism will be 36 cm^3
Answer:
Step-by-step explanation:
Volume of rectangular prism=w x h x l
V=12cm^2 x 3 1/3
V=12cm^2 x 1
V=12cm^3
please help What number should be placed in the box to help complete the division calculation?
Answer:
702
Step-by-step explanation:
The best way to do it is to divide 13 into 702. 13 doesn't go into 7 but it does go into 70 5 times. 70 - 65 = 5. Once you bring down the 2, 5 turns into 52 which 13 goes evenly into it 4 times. So your answer for that is 54. Then to get your number you multiply 54 with 13 and you get 702. So 702 is your answer.

How to express 5 x 5 x 5 using exponent?
(A) 103 (B) 53 (C) 23
Answer:
B
Step-by-step explanation:
An exponent is a number multiplied by itself several times. 5x5x5 is multiplying 5 three times, so it would be 5 to the power of 3.
Hey there!
5 * 5 * 5
= 5^3
= 25 * 5
= 25 + 25 + 25 + 25 + 25
= 50 + 50 + 25
= 100 + 25
= 125
Thus, the equation answer should be:
125
Therefore, the overall answer should be: 5^3
(Because you’re EXPRESSING 5 THREE times)

Write an equation of a line that passes through the point (7, 3) and is parallel to the line y = negative 2 over 3x + 3. y = 3 over 2x − 3 y = 3 over 2x + 3 y = negative 2 over 3x + 23 over 3 y = negative 2 over 3x − 23 over 3
The equation of line parallel to y = -2/3x + 3 and passing through (7, 3) will be y = -2/3 x + 23 / 3. Then the correct option is C.
What are parallel lines?When the distance between the lines is constant then the lines are called parallel lines. The lines do not intersect when they are separated from each other. And the slope of the lines is equal.
The equation of a line is given below.
y = -2/3 x + 3
Then the slope of the line will be
m = -2/3
Then the equation line which is having a slope of - 2/3 will be
y = -2/3 x + c
The line is passing through (7, 3). Then we have
3 = -(2/3) (7) + c
3 = -14/3 + c
c = 3 + 14/3
c = 23/3
Then the equation will be
y = -2/3 x + 23 / 3
Then the correct option is C.
