Answer:
x=15 y=22.5
Step-by-step explanation:
6x-5=85
6x=90
x=15
4y=90
y=22.5
4y makes a right angle so it is 90 degrees

Answer:
b. Continuous
Step-by-step explanation:
Continuous variable is a variable that can take on any value between its minimum value and its maximum value. A continuous variable is a type of quantitative variable used to describe data that is measurable while Discrete variables are countable in a finite amount of time. Now, justifying whether the gallons of gasoline pumped by a filling station during a day is continuous or discrete. The number of gallons of gasoline pumped by a filling during during a day is a continuous variable because it has a measurable volume which can take value from the minimum to maximum values of the total volume of gasoline the filling station have in the storage tank.
Answer:
<em>V = 65.9 cubic millimeters</em>
Step-by-step explanation:
<u>The Volume of a Right Circular Cone</u>
Given a right circular cone of radius r and height h, its volume is calculated as follows:
The cone shown in the image has a radius of r=3 mm and a height of h=7 mm, thus the volume is:
Taking pi as 3.14:
Calculating:
V = 65.9 cubic millimeters
Answer:
Line A.
Step-by-step explanation:
When you put x as zero into 3x-2, you get 3(0)-2. That equals -2. Therefore, y = -2. When x=0, that is the y-intercept, so the y-intercept is -2. Line A crosses the y-axis at -2, so line A has that y-intercept.
Slope is always y/x. On a graph, that is the number of squares UP over the number of squares ACROSS. Counting, we get, 3 squares up over 1 square across for line A. 3/1= 3. The slope is the number we multiply by x. In the equation, that is 3, because we see 3x, and no sign or space between 2 numbers automatically means we multiply. So line A also has the correct slope.
In linear equations (straight lines), the same slope and y-intercept are enough to tell you that the equation matches the line.
Therefore, the answer is A!
