A. 300 in²
B. 360 in²
C. 204 in²
D. 420 in²
Answer:
B. 360 in²
Step-by-step explanation:
Rectangle 1
length = 12 in
breadth = 12 in
Surface area = length × breadth
⇒Surface area = 12 × 12
⇒Surface area = 144 inch²
Rectangle 3 (behind)
length = 12 in
breadth = 13 in
Surface area = length × breadth
⇒Surface area = 12 × 13
⇒Surface area = 156 inch²
Rectangle 2
length = 12 in
breadth = 5 in
Surface area = length × breadth
⇒Surface area = 12 × 5
⇒Surface area = 60 inch²
Adding the 3 areas we get
144+156+60 = 360 in²
∴ 360 in² of paint is needed to cover all the rectangular faces of the prism.
To solve this problem, one must find the surface area of the rectangles. This is the total area of each rectangle added together. The formula for the area of the rectangle is w*l=A
Rectangle one: 13*12 = 156 in^2
Rectangle two: 5*12 = 60 in^2
Rectangle three: 12*12 = 144 in^2
156 + 60 + 144 = 360 in^2
This means total to paint the rectangle sides of the prism, we need 360 in^2 of paint.
Answer:
i) Line
ii) point
Step-by-step explanation:
Given is a number 3. We have to find the kind or kinds of symmetry
On seeing 3, we find that no vertical line can divide 3 into exactly two symmetrical figures.
But if we draw a horizontal line in the middle of 3, we get two symmetrical figures up and down the line.
Hence i) symmetric about a line
Next is imaging the middle of 3 end point.
At that point we find that the figure is symmetrical on all sides of the point
Hence there is also a point symmetry
Kinds of symmetry are
i) Line
ii) point
A. 600
B. 0.06
Answer: Complete the statement: 0.6L =______mL.
A. 600
The solution to the equation 5x = 30 is x = 6
From the question, we have the following parameters that can be used in our computation:
5x = 30
Divide both sides of the equation by 5
So, we have the following representation
5x/4 = 30/5
Evaluate the quotient
x = 6
Hence, the solution to the equation is x = 6

Answer: x = 6 or in other words the answer to this question is 6.
Step-by-step explanation: We will need to isolate the variable x so we divide both sides by 5 and get our solution of 6.
of the following intervals contains the x-coordinate
of the vertex of the graph of f?
Answer:
Below in bold.
Step-by-step explanation:
The zeroes ( = x-intercepts) are x = -3 and x = -1.
So the x -coordinate of the vertex is between x = -3 and x = -1.
The actual x-coordinate is halfway between these value: at x = -2.
Answer:
x = -3 or x = -1
Step-by-step explanation:
f(x) = (x + 3)(x + 1)
⇒ x = -3 or x = -1
