Answer:
breadth = 4 ft ; length = 12 ft
Step-by-step explanation:
p/2 = 32/2 = 16ft
l + b = 16
b = 1/3 l
l + 1/3 l = 16
(3 + 1)/3 l = 16
4/3 l = 16
l = 16 · 3/4
l = 4 · 3
l = 12 ft
b = 12 · 1/3
b = 4 ft

What is a number line?A number line refers to a straight line in mathematics that has numbers arranged at regular intervals or portions along its width. A number line is often shown horizontally and can be postponed in any direction.
Cecil started from Point A and moved according to the expression 10 + (−5) + 19 + 6 + (−19) + 5 + (−10).
Let 'x' be the number of steps in order to return to the starting point. Then the equation is given as,
x + 10 + (−5) + 19 + 6 + (−19) + 5 + (−10) = 0
Simplify the equation, then the equation is given as,
x + 10 − 5 + 19 + 6 − 19 + 5 − 10 = 0
x + 40 − 24 = 0
x + 16 = 0
x = − 16
The number of steps in order to return to the starting point will be negative 16.

Answer:
∆QRS / ∆XZY = 1/2
Step-by-step explanation:
You want the similarity ratio of ∆QRS to ∆XZY. Side lengths are marked in the diagram.
The similarity ratio will be the ratio of two corresponding side lengths.
Corresponding sidesYou can find corresponding sides several ways:
Use the similarity statement to identify corresponding vertices. A side will be defined by 2 of them. Use vertex identifiers that are in the same positions in both triangle names: QR : XZ (first two vertices listed), for example.Use the markings in the figure to identify corresponding sides. Corresponding sides will have the same angle marks at either end. For example, the side marked 1 in ∆QRS has 1-arc and 3-arc angle markings at its ends. The side marked 2 in ∆XZY also has 1-arc and 3-arc angle markings at either end. It will be the corresponding side.Use side lengths. When both triangles have their side lengths sorted into increasing order, the corresponding numbers are corresponding sides. The side lengths in ∆QRS are {1, 2, 2}. In ∆XZY, they are {2, 4, 4}.The ratios of corresponding sides are 1:2, 2:4, and 2:4. The 2:4 ratios reduce to 1:2, which is the answer you're looking for. Written as a fraction, the ratio is ...
1/2 . . . . ratio of ∆QRS to ∆XZY

I just need to know how to get to 55 pls
Answer/Step-by-step explanation:
Okay, so this question really is a nightmare, because this image is just not possible. Like, literally, Z is or is not the center, you do or do not have enough info. Its a bad question. This is not your fault. If you don't care why its a bad question scroll down to "How could someone get 55°"
If Z is the center, BZ and CZ are radii and equal. Angle CBZ is 60° because
AngleABC + Angle CBZ = 180°
120° + CBZ = 180°
CBZ = 60°
That means AngleC is also 60°. And then, since 180° in a triangle, AngleCZB also must be 60°.
This makes AngleCZD 120°.
But if Z is the center and ArcCD is 115°, then AngleCZD should be 115°.
Contradiction! Angle CZD can't be both 120° and 115° something is wrong here. See image.
How could someone get 55°? Well, it is also not correct but... If ArcCD is 115° then AngleCZD is 115° (if Z is the center) So AngleCZB is 180°-115°, which is 65°.
AngleCBZ is 60°
60° + 65° + C = 180°
125 + C = 180
C = 55°

Selected values of the continuous function f are shown in the table below. Determine the validity of the following statement:
f(x)=0 has at least two solutionsin the interval {2,9}
True
False
could be true or false
Function may return true or false.
What does "continuous function" mean?A continuous function is one in which a continuous variation of the input (i.e., a change without a jump) results in a continuous modification of the function's value. This indicates that there aren't any discontinuities, or sudden changes in value.
Here, the function f(x) is continuous.
It follows that if x = 2 then f(x) = 3,
if x = 5 then f(x) = -9,
if x = 7 then f(x) = -15,
if x = 9 then f(x) = -13.
There are at least two solutions in the interval {2,9} for the graph of the function cross x axis f(x) = 0, hence it is not provided.
Therefore, it may be true or false.

How do I do y=mx+b in these type of questions
1. y<-3/4x+2
2. y≤5
3. x+y>6
With linear inequalities in two variables, you still have y=mx+b and it still tells you the same thing.
The inequality portion adds two additional layers on top of the y=mx+b line.
If the inequality is > or <, then you draw the line as a dashed line.
If the inequality is ≥ or ≤, then you draw the line as a solid line.
The difference is that points on the > or < line do NOT make the inquality true, while points on the ≥ or ≤ line do.
The other piece is that all the points on one side of the line will also make the inequality true.
If you have "y>mx+b" or "y≥mx+b", then you shade above the line.
If you have "y<mx+b" or "y≤mx+b", then you shade below the line.
So there are three parts:
1. Where is the line?
2. Is the line solid or dashed?
3. Do you shade above or below the line?
The three graphs are attached.

The dimensions of the rectangular prism are:
Length = 4 meters.
Width = 2 meters.
Height = 2 meters.
What are the dimensions of the storage space?A rectangular prism of width W, height H, and length L has a volume given by the formula:V = W*H*L
Here we know that: the height and the width are both 2 meters less than the depth, then:W = L - 2H = L - 2 and the volume is 16 cubic meters
Replacing that in the volume equation we will get:16 = L*(L - 2)*(L - 2)It is ratter easy to notice that if we take L = 4, we will get:16 = 4*(4 - 2)*(4 - 2) 16 = 4*(2)*(2)16 = 4*416 = 16 So L = 4 is a solution, then:
W = L - 2W
= 4 - 2 = 2

Write an equation in slope-intercept form of the line that is perpendicular to the one given and passes through the given point. (4,8); y=-2x - 4
An equation in slope-intercept form of the line perpendicular to y = 2x-4
is y =(-1/2)x+10.
What are lines and their slopes?We are aware that there are many types of equations for lines, with the
general type being Ax+ By + C = 0, and the slope-intercept form equation
being y = mx + b.
m is the slope, and b is the y-intercept.
The y-intercept is the point (0,b) where the line intersects the y-axis when
x = 0, and the slope is the rate of change of the y-axis relative to the x-axis.
We are aware that the slopes of perpendicular lines are oppositely negative.
The slope of the given line, y = 2x-4, is 2.
Consequently, the given line will pass through point with a slope of (-1/2). (4,8).
∴8= (-1/2)(4)+b
8= -2+b
b = 10.
∴ y =(-1/2)x+10 is our required line.
