Answer:
0.08 pounds per pint.
Step-by-step explanation:
Given: The density of a certain material is such that it weighs 10 ounces per gallon.
We are to express this density in pounds per pint.
1 gallon ⇒ 10 ounces
1 pound = 16 ounces
How many pounds? = 10 ounces.
Cross-multiplying gives;
pounds
1 gallon = 8 pints
The density in pounds per pint is;
0.625 pounds ÷ 8 pints = 0.078125 pounds per pint = 0.08 pounds per pint (answer rounded up to the nearest hundredth).
Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0)
You need to find "m" and "b".
In the table, when x = 0, y is 0, so the y-intercept is 0
y = mx + 0 or y = mx
To find "m", you can use the slope formula and plug in 2 points:
(0,0) and (1, 3)
m = 3
Slope: 3
y-intercept: 0
Equation: y = 3x
Answer:
first one
Step-by-step explanation:
same x value can't have more than one y value
Answer:
the answer is D (9)
Step-by-step explanation:
3(n-5)=12
3n-15=12
add 15 on both sides
3n=27
divide both sides by 3
n=9
1/2 chance of one baby being a boy
1/2*7
7:2 chance
