Answer:
y=40
Step-by-step explanation:
If y varies jointly as a and b
y∝ab
If y varies inversely as the square root of c
y∝
Combining the two
y∝
Introducing Variation Constant
y=16, When a=4, b=5, c=25
Therefore the equation connecting a. b and c is:
We are to determine y when a=5, b=4 and c=4
Answer choice C divide by 4.
Answer:
complementary, x=60
Step-by-step explanation:
complementary angles add up to 90 degrees.
90= x + x- 30
2x= 120
x= 60
Answer:
Step-by-step explanation:
The shape of the container isn’t changing here, so the height of the water will be proportional to the volume. 75 cm^3 is ¾ of 100 cm^3, so the water will rise ¾ as high.
¾ of 8 cm is 6 cm.
Answer:
y = -1/3x + 3
Step-by-step explanation:
Slope = -1/3
Y-intercept = (0, 3)
