Answer:
25 unit
Step-by-step explanation:
from the diagram
QS=QR+RS
26=(2x-39)+(x+5)
26=3x-34
3x=34+26
3x=60
x=60/3
x=20
now
RS=x+5
RS=20+5
RS=25 unit
Answer/Step-by-step explanation:
This is a proportional relationship between amount of strawberries and the amount of bananas needed in making smoothie.
Thus, a constant of proportionality, k, is a ratio that exist between both quantities.
k = y/x = amount of strawberry/amount of bananas.
Since we are given that a recipe of smoothie contains 5 cups of strawberries for every 2 cups of bananas, therefore,
k = ⁵/2 = 2.5.
Any point that will be on the line shown must have the same value of k (y/x).
Thus, given the point (1, 2.5). The ratio between y and x is:
k = 2.5/1 = 2.5.
Since this also shows the same constant of proportionality as 2.5, therefore, the point is also on the line.
Break it up into two rectangular solids. like two legos stuck together.
top is 10x4x3 = 120
bottom is 2x4x4 = 36
combined 120+36=156 ft²
