Answer:
4/9
Step-by-step explanation:
The exponent value would be 3
Answer:
Area = 28 cm² (check the attached diagram for better clarity)
Step-by-step explanation:
The question is incomplete but let's see a similar example
The front of a rectangular pyramid can refer to either one of two possibilities: it could be either the side that has the breadth and the height or the side that has the length and the height. In this case, we were given the formula for calculating the area of the front face of this rectangular prism as the product of breadth and height
Mathematically,
A = bh
From the attached diagram, we will see the properties of the rectangular prism as:
length = 5 cm, breadth = 4 cm, height = 7 cm
To calculate for the front face, we use A = bh,
⇒ A = 4 * 7 = 28 cm²
Example 2
If the breadth of the rectangular prism is 2 cm and the height is 3 cm, we have:
A = 2 * 3 = 6 cm²
Probably the last option. Because it has the points shown on the coordinate graph.
Answer:
B
Step-by-step explanation:
Our system of equations is:
3x + y = 23
8x + 2y = 23
If we want to use substitution, that means that we essentially want to manipulate one of the two equations so that one variable (like y) is written in terms of the other (like x), and then substitute that expression into the second equation so that we have one variable and one equation and we can easily solve from there.
So the first thing to be done is to write one of the variables in terms of the other. It would be easiest to do it with the first equation and write y in terms of x - in other words, "solve the first equation for y".
The answer is B.
