1)1.10w+2.35(172-s)=294.20
When you solve
1.10x+2.35(172-x)=294.20 solve for x
X water=88
S=172-88=84
2)2t+4(40-f)=100
When you solve
2x+4(40-x)=100 solve for x
X=30 for t
40-30=10 for f
Hope it helps
Answer:
b = ⅓
x = ½, -1/7
Step-by-step explanation:
(b−5)x² − (b−2)x + b = 0
(b - 5)(0.5)² - (b - 2)(0.5) + b = 0
0.25b - 1.25 - 0.5b + 1 + b = 0
0.75b = 0.25
b = ⅓
(⅓−5)x² − (⅓−2)x + ⅓ = 0
(-14/3)x² + (5/3)x + 1/3 = 0
14x² - 5x - 1 = 0
14x² - 7x + 2x - 1 = 0
7x(2x - 1) + (2x - 1) = 0
(7x + 1)(2x - 1) = 0
x = 0.5, -1/7
Answer:
B. Time(length)
Step-by-step explanation:
The function that would be represented as a good name for a function for the length of the race and the return the time required to finished it
here the independent variable or the INPUT is the length while the output would be the time that required to finish it
Hence, the correct option is B,
Therefore all the other options would be incorrect
A: to find rate of change you take the smallest rate:
2 bushels/$15 and divide both by 2 so that you get 1 bushel and $15/2=$7.5, therefor 1 bushel/$7.50.
B:The current year is at 2 bushels/$16 or 1 bushel/$8, which is $.50 more than the previous year.
Answer:
20 yards
Step-by-step explanation:
Since it is an isosceles triangle, a perpendicular from it's peak to the base bisects the base.
30/2=15
So using the Pythagorean theorem, hypotenuse^2=base^2+height^2
25^2=15^2+H^2
625=225+H^2
H^2=400
height=20 yards
