What is the density of a 60-gram pyramid with rectangular base 5 cm x 7 cm and height 9 cm?
Answers
Answer:
A
Step-by-step explanation:
The density of the pyramid is approximately 0.57 grams per cubic centimeter.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
To find the density of the pyramid, we need to know its volume as well as its mass.
The volume of a pyramid is given by:
V = (1/3) × base area × height
The base of the pyramid is a rectangle with dimensions 5 cm by 7 cm, so its area is:
A = 5 cm × 7 cm
= 35 cm²
Using the formula for the volume of a pyramid, we have:
V = (1/3) × A× h
V = (1/3) × 35 cm² × 9 cm
V = 105 cm³
Now we can calculate the density:
density = mass / volume
Since the mass of the pyramid is given as 60 grams, we have:
density = 60 g / 105 cm³
To get the density in units of grams per cubic centimeter, we need to convert the units of mass and volume to grams and cubic centimeters, respectively:
density = (60 g / 1000) / (105 cm³ / 1000)
density = 0.57 g/cm³
Therefore, the density of the pyramid is approximately 0.57 grams per cubic centimeter.

Write the equation for a circle with a center at (-7 , -4) and a radius of 2.
Answers
Answer:
(x + 7)² + (y + 4) ² = 2²
Step-by-step explanation:
Start with the standard equation of a circle with center at (h, k) and radius r:
(x - h)² + (y - k)² = r²
Here we are given that h = -7, k = -4 and r = 2, and so we obtain:
(x + 7)² + (y + 4) ² = 2²
Step-by-step explanation:
The answer is above, as well as the equation used to get to the answer.

Answer:
k = 5.25
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of proportionality
To find k use the condition y = 84 and x = 16 , then
84 = 16k ( divide both sides by 16 )
5.25 = k

What is the equation of a circle with a center located at (-3, 4) and a diameter of 14?
Answers
Answer: (x + 3)^2 + (y - 4)^2 = 49
Step-by-step explanation:
The equation of a circle given the center and radius: (x - h)^2 + (y - k)^2 = r^2
Given: center (-3,4) ; h = -3 and k = 4
diameter = 14
To find the radius: divide the diameter by 2 = 14/2 = 7 = r
Center: (-3,4) and radius: 7
Equation of a circle: (x - h)^2 + (y - k) ^2 = r^2
Substitute h = -3, k = 4, r = 7
(x - (-3))^2 + (y - 4)^2 = 7^2
Answer:
Equation of the circle: (x + 3)^2 + (y - 4)^2 = 49
