It would be 115
180-65 = 115 and 180 comes from the straight line which is half of 360
Answer:
240
12.5p + 65
14
p
Step-by-step explanation:
I'll explain the equation in different parts
12.5p - Since the number of times he visits is unknown, it has to be a variable. With each visit, however, he earns 12.5 points.
65 - This is a set value that remains constant
240
- Since he needs AT LEAST 240 points, he needs 240 points or more to get his free ticket
As for solving the equation just use properties of equality
240
12.5p + 65
175
12.5p
14
p
Answer:
There area 14 one cent stamps
Step-by-step explanation:
Let
x -----> the number of 1 cent stamps
y -----> the number of 8 cent stamps
z -----> the number of 12 cent stamps
we know that
0.01x+0.08y+0.12z=1.78 -------> equation A
x=y+4 ------> y=x-4 -----> equation B
x=2z -----> z=0.5x ------> equation C
substitute equation B and equation C in equation A and solve for x
0.01x+0.08(x-4)+0.12(0.5x)=1.78
0.01x+0.08x-0.32+0.06x=1.78
0.15x=1.78 +0.32
0.15x=2.10
x=14
therefore
There area 14 one cent stamps
What do u need help with like what’s the question
Answer:
the height of the water in the pool is 2m
Step-by-step explanation:
This problem bothers on the mensuration of solids.
Given data
Volume of pool v= 270m³
Base length l= 15m
Base width b= 9m
Height h=?
The pool takes the shape of a rectangular prism
The expression for the volume of the pool is
v= l*b*h
Substituting our given data we have
270= 15*9*h
270= 135h
h= 270/135
h= 2
Therefore the height h =2m
