First we have to see the formula of profit, which is
And it is given that profit should be atleast $150, that is
Let Ritax dollars per cake, so for 15 cakes, she charge 15x .
And she epent 30 dollars for 15 cakes.
So we will get
Adding 30 to both sides
Correct option is the second option .
Answer: 8 & 13
Step-by-step explanation:
13 squared is 169 and 8 squared is 64, and the difference of those two squares would be 169 - 64 = 105. Hope this helps!
If i’m not mistaken it’s the second choice 216. 12x18=216
Answer:
4
Step-by-step explanation:
Two perpendicular lines must have a slope that multiplies to -1. With this in mind, we take the slope from the given equation, -1/4, and add multiply it by a variable new slope, z. We get the equation -1=-1/4z
Working it out:
-1=-1/4z
-1/-1/4=-1/4z/-1/4 (The two -1/4's on the right cancel out, leaving us with just z on the right side. -1 divided by -1/4 is equal to 4)
4=z
The slope of your line perpendicular to the given line is 4.
A trick for me to remember this is the answer for a perpendicular slope is the negative reciprocal. Add a negative sign to the number and flip it. It will never be wrong if worked out correctly. I can help you with this strategy more if you ask.
