pls tell me which to pick (a,b,c,or d)
Answers
Answer:
B (Y, N, N)
Step-by-step explanation:
a) y = 1/3x, so each value satisfies it. This is true.
b) If "a" is "Y" then b has to be no
c) 1 * 11 = 11
2 * 2 = 22
3 * 5 = 15
The last equation does not follow the rules for the previous two equations, so it is no.
Thus, the answer is B (Y, N, N)
A cashier can ring up 12 items per minute. How long will it take the cashier to ring up 72 items?
Answers
Answer:
So it will take 6 minutes to ring up 72 items.
Step-by-step explanation:
Well this seems pretty simple just have to reads the question and know what to find.
So what we know :
A cashier can ring up 12 items per minute
So :
1 minute = 12 Minutes
And we have to find :
How long for 72 items
So since we know he can do 12 in a minute and it is asking how many minutes it will take for 72 we can divide.
So :
72 / 12
=
6
So it will take 6 minutes to ring up 72 items.
I hope this helps!

Step-by-step explanation:
Label the point where the altitude meets the base P and the end points of the base A and B where m∠A = 27 and m∠B = 41
tan 27 = 102/AP and tan 41 = 102/PB
APtan 27 = 102 PBtan 41 = 102
AP = 102/tan 27 PB = 102/tan 41
AP = 200.186 PB = 117.338
x = AP + PB = 200.186 + 117.338 = 317.52

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
1. 5 + 0 = 0
5 = 0
This is not an equation because LHS ≠ RHS.
2. 15 x 0 =0
0= 0
This is an Equation.
