Answer:
Step-by-step explanation:
since 105 + z is a straight line we know it equals 180 so we can use this equation
180 = 105 + z
simplify
75 = z
the since we know that all quadrilaterals equal 360 degrees we can add our two given number and z then subtract from 360:
102 + 85 + 75
= 262
now subtract
360 - 262
= 98
y = 98

Answer:
first he had M some unknown amount
then he had 2/3 M since he spent 1/3 M
then he spent 3/4 of the (2/3 M) so he had 1/4 of the ( 2/3M)
then he spent what was left $20 so $20 = 1/4 ( 2/3 M) now solve for M
and check by doing each step and figuring how much was spent and how much left.
<u>another</u><u> </u><u>method</u><u> </u>
let us consider the left amount be Y and total now of M dollar be X
then
Y = amount of money Nartin has left
Y = X - ( 1/3 ) ( X ) - ( 3/4 ) ( X - 1/3 X ) - 20
Y = X - 1/3 X - 3/4 X + 3/12 X - 20
Y = X - 4/12 X - 9/12 X + 3/12 X - 20
Y = X - 10/12 X - 20
Y = X - 5/6 X - 20
Y = ( 1 / 6 ) ( X ) - 20

Answer: The correct answer is 94 cm.
Step-by-step explanation:
wingspan length
60 meters 70.5 m
----------------- = ----------------
80 cm x
Cross multiply
(60 m)x = (70.5 m)(80 cm)
Solve for x by dividing both sides of equation by 60 m:
x = (70.5 m)(80 cm) / (60 m) = 94 cm
The length of the model is 94 cm.
15 × h
h= per hour
and to solve how many hours it would take:
600= 15 × h
600÷ 15 = 40
so it would take 40 hours to rise to the surface
