Answer:
She had a success rate of 60 %.
Step-by-step explanation:
In order to calculate her percentage of success we need to take the total amount of shots she made and divide it by the total amounts of shots she attempted and multiply it by 100. Since she took 25 shoots and made 15, we have:
percentage of success = (15/25)*100% = 0.6*100% = 60 %
She had a success rate of 60 %.
Y = -0.4x
1) It is a straight line
2) I passes through the origin (0,0), because the y-intercpet is 0.
3) The slope is negative, so it passes throuh II and III quadrants
4) The magnitude of the slope = 0.4
4) The angle of the line with the negative side of the x-axis is that whose tan is 0.4 => angle = 21.8 °
With all that information you can identify the graph, given that you didn't include the options.
Step-by-step explanation:
here
f(x)=2x^2-1
Now
f(4y)=2*4y^2-1
Maria had 2 yards of trim when she started.
Step-by-step explanation:
Step 1:
All of the sides of the triangle is 22 inches long each.
The total length of the sides of the triangle 
So the total length of the trim for the banner is 66 inches long.
If Maria still has 
a foot of trim left, she had 6 inches of the trim left.
The length of the trim when she started
inches.
Step 2:
Now we need to convert the 72 inches into yards.
We have 1 inch = 0.0277778 yards.
So 72 inches 
So Maria had 2 yards of trim when she started.
