Angles B and W are supplementary. Angle B has a measure of (4x+16)˚. Angle W has a measure of 68˚.
What is the value of x?
Answer:
Step-by-step explanation:
first, set angle b+w=180. You do this because both of the angles added together equals 180°.
Second, begin to isolate the variable. 4x+16 +68= 180
4x = 96
x = 24

Which of expressions illustrates the associative property?
ab + bc
a ( b + c ) = ab + bc
a ( b + c ) = (a + b ) + c
a + b + c = c + b + a
Answer:
c) a ( b + c ) = (a + b ) + c
Step-by-step explanation:
The associative property is a property of some binary operations, which means that rearranging the parentheses in an expression will not change the result. In propositional logic, associativity is a valid rule of replacement for expressions in logical proofs.

number 2 is 0.7
Step-by-step explanation:
Scince they are negative, adding is technically making the number lower, so
-16+-33=-49
2. Is 0.7 because if you convert 2 and 8/10 into decimal form it's 2.8
So 2.8 plus -3.5 is 0.7

Step-by-step explanation:
A rectangle has a length that is unknown but is 12 inches longer than its width, w. The perimeter of the rectangle is 104 inches.
(a) Write an expression for the length of the rectangle in terms of w. Label it on the diagram. (b) Write an equation using the perimeter to find the value of w. Solve it for w.
Answer:
[tex]2w+2(w+12)=P (104)[/tex] and [tex]w=20[/tex]
Step-by-step explanation:
We know that the following equation represents the problem:
[tex]2w+2(w+12)= P[/tex]
So this means that we can do this:
[tex]4w+24= P[/tex]
We know that [tex]P[/tex] is 104. We need to fix our current equation, giving us:
[tex]4w+24=104[/tex]
We can subtract 24 to give us [tex]w[/tex] as a standalone with a coefficient.
[tex]104-24=80[/tex]
[tex]4w=80[/tex]
Then, simply divide the answer by the coefficient to give us the answer of:
[tex]80/4=20\\[/tex]
[tex]w=20[/tex]
[tex]w[/tex] is 20.

A rectangular prism has a volume of 198 cm³. A rectangular pyramid has the same height as the rectangular prism and a base that is congruent to the base of the rectangular prism.
What is the relationship between the volume of the rectangular prism and the rectangular pyramid?
The volume of a rectangular pyramid is 3 times the volume of a rectangular prism. The volume of the rectangular pyramid is 594 cm3.
The volume of a rectangular pyramid is 12 the volume of a rectangular prism. The volume of the rectangular pyramid is 99 cm3.
The volume of a rectangular pyramid is 13 the volume of a rectangular prism. The volume of the rectangular pyramid is 66 cm3.
The volume of a rectangular pyramid is 2 times the volume of a rectangular prism. The volume of the rectangular pyramid is 396 cm3.
9514 1404 393
Answer:
(c) The volume of a rectangular pyramid is 1/3 the volume of a rectangular prism. The volume of the rectangular pyramid is 66 cm3.
Step-by-step explanation:
The pyramid with the same overall dimensions will obviously have a smaller volume. The ratio is 1/3.
__
The formula for the volume of a rectangular prism is ...
V = LWH
The formula for the volume of a rectangular pyramid is ...
V = (1/3)LWH
The pyramid has 1/3 the volume of the prism.
Answer:
The volume of a rectangular pyramid is 1/3 the volume of a rectangular prism. The volume of the rectangular pyramid is 66cm³

1. the pristine data set,makes it different from the residual plot in points from an arbitrary scatter.
2.a linear patter shows some data of numerical bivariate of a scatter plot, the Residual plot would look homogeneous to, If the points in a residual plot are arbitrarily dispersed around the horizontal axis, a linear regression model is felicitous for the data; otherwise, a nonlinear model is more congruous.
