Answer:
4/5 or -4/5
Step-by-step explanation:
We are going to use the Pythagorean Identity:
We are given the value of which is 3/5 so plug that in:
Simplify:
Subtract 9/25 on both sides:
Take the square root of both sides:
has an inner diameter of
2.7 cm and an outer
diameter of 3.6 cm. If the
density of stainless-steel
is 8 g/cm3, what is the
mass of the fitting?
Subtract the volume of the inside diameter from the volume of the outside diameter and then multiply that by the density.
Volume of outside:
PI x 1.8^2 x 3.9 = 39.67704 cubic cm
Volume of inside:
PI x 1.35^2 x 3.9 = 22.318335 cubic cm
Difference: 39.67704 - 22.318335 = 17.358705 cubic cm.
Mass = 17.358705 x 8 = 138.86964 grams. Round the answer as needed.
Answer:
Let x be the number of albums to be bought and
let y be the number of movies to be bought.
The amount to be spent on albums is 10x and
The amount to be spent on movies is 30y.
As per the given condition: The total amout to be spent must equal $ 150.
then, we have
......[1]
Now, find x-intercepts and y-intercepts of equation [1];
x-intercepts defined as the graph crosses the x-axis.
Substitute y= 0 in [1] to solve for x;
10x =150
Divide both sides by 10 we get;
Simplify:
x = 15
y-intercepts defined as the graph crosses the y-axis.
Substitute value of x=0 in [1] to solve for y;
10(0)+30y = 150
30y =150
Divide both sides by 30 we get;
y =5
Now, plot these points (0, 5) and (15, 0) on graph and connect them with a line as shown in the figure below;
Answer:
x + 3y = 15
The graph is attached below.
Step-by-step explanation:
Given the price of album = $10.
and the price of movies = $30.
Let's assume she buys "X" albums and "Y" movies.
Cost would be (10X + 30Y).
She plans to spend a total of $150, so cost would be same as total expenditure.
10X + 30Y = 150
X + 3Y = 15
we can graph this equation of line on a graph paper as given below:-
