At Dustin's Hats, 10 out of the 25 hats at the store are baseball caps. What percentage of hats at the store are baseball caps?
Answers
Answer:
BaseBall hats: 40%
Other Hats: 60%
Step-by-step explanation:
10/25= baseball hats or: 10*4: 25*4: 40/100: 40%
15/25= other hats: 15*4/25*4=60/100/ 60%
So 40% are baseball caps
(sinA + cosA)/ (secA + cosecA) = sinA* cosA
Answers
Answer:
Proof below
Step-by-step explanation:
Trigonometric Identities
We'll prove that:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\sin A*\cos A[/tex]
Recall:
[tex]\displaystyle \sec A =\frac{1}{\cos A}[/tex]
[tex]\displaystyle \csc A =\frac{1}{\sin A}[/tex]
Applying those definitions:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\frac{\sin A+\cos A}{\frac{1}{\cos A}+\frac{1}{\sin A}}[/tex]
Adding the fractions:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\frac{\sin A+\cos A}{\frac{\sin A+\cos A}{\cos A*\sin A}}[/tex]
Dividing the fractions:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=(\sin A+\cos A)*\frac{\cos A*\sin A}{\sin A+\cos A}[/tex]
Simplifying:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\cos A*\sin A[/tex]
Hence proved

y =[tex]-\frac{1}{2}[/tex] x + 5
Step-by-step explanation:
Given parameters:
Coordinates = (-6,2)
Slope = [tex]-\frac{1}{2}[/tex]
Unknown:
Equation of the line that passes through = ?
Solution:
The equation of a line is expressed as;
y =mx + c
y and x are the coordinates
m is the slope
c is the y-intercept
let us find c;
2 = [tex]-\frac{1}{2}[/tex] x 6 + c
2 = -3 + c
c = 5;
The equation of the line is;
y =[tex]-\frac{1}{2}[/tex] x + 5

Ben is going to make 1/4 pound burgers for a barbecue next weekend. He is planning on making 19 burgers. How much hamburger meat will he need to make 19 quarter pound burgers?
Answers
Answer:
4.75 pounds of hamburger meat
Step-by-step explanation:
In order to calculate the total amount of hamburger meat that Ben would need we would need to multiply the total number of burgers that he wants to make (19) by the amount of meat each burger will use (1/4 pound or 0.25 pound). Therefore, we would do the following...
19 * 0.25 = 4.75 pounds
Finally, we can see that Ben would need a total of 4.75 pounds of hamburger meat to make 19 equal sized 1/4 pound burgers.

Option C
Step-by-step explanation:
Since it's draining, it means it must start at a certain value and end at a maximum of 0 since water cannot ever be less than 0. Since it's original amount is 40, it can only start draining from 40 and end at max 0 hence 0 ≤ y ≤ 40
