HELP ME! Deandre estimated the weight of his mountain bike to be 13 kg. The actual weight of his mountain bike was 12.7 kg.
Find the absolute error and the percent error of Deandre's estimate. If necessary, round your answers to the nearest tenth.
Answer:
Absolute error = 13-12.7=0.3
13 =100%
12.7=x
x=(12.7)(100)/13
x=97.7
the percentage error is 97.7%

Answer:

Step-by-step explanation:
Cus the other guy is big brain
The scale factor of the dilation of line segment BA is 5.
What is Scale factor?To adjust the size of a figure without altering its shape, a scale factor is a number or conversion factor that is utilised. It is employed to change the size of an object. If the original figure's dimensions and the dilated (increased or lowered) figure's dimensions are known, the scale factor can be determined.
When both the original dimensions and the new dimensions are known, the scale factor may be determined. When employing the scale factor, there are two terms that must be understood. When a figure's size is increased, we refer to this as scaling up, and when its size is decreased, we refer to this as scaling down.
Given:
AC= 4
AA' = 16
and, A'C= 16+ 4 = 20
So, scale factor = AC/ A'C
= 4/5
= 1/5
Hence, the scale factor of the dilation of line segment BA is 5.

Point P is the centroid of LMN. Find PN
Answer:
PN = 14
QP = 7
Step-by-step explanation:
Extend PQ to R so that QR=PQ
MQ = QL (known, mid-point)
MPLR is parallelogram (diagonal bisect each other)
MP // RL NP/PR = NE/EL = 1/1 (E mid-point, known)
NP = PR
PQ = QR = 1/2 PR = 1/2 NP
NP = 2 PQ
NP + PQ = 2PQ + PQ = 3 PQ = QN = 21
PQ = 7
PN = 14

Which number line best shows the position of square root of 7?
Step-by-step explanation:
First off, you want to find the whole number in square root form
1 = √1
2 = √4
3 = √9
4 = √16
5 = √25
You want to find which to numbers √7 is in between
7 is between 4 and 9 so the √7 is in between √4 and √9 which means that √7 is between 2 and 3
The second one is your answer

14 years ago the age of the mother was 4 times the age of her daughter. The presen
age of the mother is 2 times the age of her daughter will be 4 years hence. What
their present ages?
Answer:
Daughter is 25, mother is 58
Step-by-step explanation:
Let m = age of mother now
Let d = age of daughter now
m - 14 = 4(d - 14)
m = 2(d + 4)
m - 14 = 4d - 56
m = 2d + 8
subtracting them gets
14 = -2d + 64
2d = 50.
d = 25
m = 58

The surface area of the prism is 48 units².
Step-by-step explanation:
Remember, a net is simply the outer surface of a 3D shape flattened and spread out as a combination of 2D shapes.
With this info, the rest is relatively easy.
The net shows that there are 4 rectangular sides and 2 square sides. We also know the lengths and widths of all of them.
One rectangle is 5 units long and 2 units wide. One square is 2 units long and 2 units wide.
Let's put this into an equation.
4( 5*2 ) + 2( 2*2)
We are adding the areas of the rectangles and squares.
So, let's simplify that equation.
4(10) + 2(4)
40 + 8

What is the measure of x
Answer:
x = 75°
Step-by-step explanation:
From the figure it appears that:
[tex] m\angle B = 36\degree [/tex]
and
[tex] m\angle D = 39\degree [/tex]
x is the measure of the exterior angle of [tex] \triangle BDH[/tex]
Therefore, by exterior angle theorem:
[tex] x = m\angle B+ m\angle D [/tex]
[tex] x = 36\degree+ 39\degree [/tex]
[tex] x =75\degree [/tex]

Write an equation of the line passing through point P that is perpendicular to the given line P(6, -3), y
Answer:
Equation of the line is: [tex]x=6[/tex]
Step-by-step explanation:
We know that , the equation of any line parallel to y axis is :
[tex]x=k[/tex] where [tex]k[/tex] ia a constant
And here it is given that the line is passing through the point P(6,-3)
Therefore, it will satisfy the equation [tex]x=k[/tex].
So, substitute [tex](6,-3)[/tex] in equation [tex]x=k[/tex], we get
[tex]k=6[/tex]
Hence the equation of line will be [tex]x=6[/tex]
