Answer:
They are two angles that have a common vertex and a common side.
Step-by-step explanation:
Well, we want to find how much it would cost for 1 gallon, the easiest way to do that is subtract 21 from 18.
21 - 18 = 3
So, it's 3 dollars per gallon. Now that we know that we multiply it by 8 to find how much it would cost.
8 x 3 = 24
Eight gallons of gas would cost 24$ :D
Answer:
x = - 6
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 9 when x = 3, thus
k = 
= 
= - 3
y = - 3x ← equation of variation
When y = 18, then
18 = - 3x ( divide both sides by - 3 )
x = - 6
Solution :
The term 'literacy rate' provides the ability of a person who is from a definite age group can read or write.
a). 
does not determine the rate at which the variable explains another, but it explains the amount the amount of variability in one of the variables as explained by the other variable.
b). The slope given provides an expected improvement but it cannot guarantee the improvement. The value may be less or it could be more also.
The regression model provides the prediction and not the actual values.
Answer:
1335cm³
Step-by-step explanation:
According to the question above,Krispy kritters cereal used to come in a box with a volume of 2,850 cm3. However, the krispy kritters co. Designed a new larger box 22.5 cm wide, 6.2 cm deep, and 30 cm high and we are now asked to find "How many more cubic centimeters will the new box hold than the old box?
Now we are all aware that the volume of a cube or cuboid(since its a box ) is length multipled by width multiplied by the height.
And we were given the new dimensions which are;
12.5cm wide
6.2cm deep and
30cm high
Apply this given figures in the formula above and we have:
V = 12.5 × 6.2 × 30
= 4185cm³( this is the volume of the new box designed by krispy kritters co for their cereal)
Therefore,the difference in volume between the new box and the old box is
4185 - 2850 = 1335cm³
