Three small squares are drawn inside a larger square as shown. What is the length of the line marked with a question mark?
Answers
Answer:
19
Step-by-step explanation:
let the smallest square be A, medium square is B and the largest is C ;
as the length side of the main square is 28, we can find that,
A= 28-22 = 6
C= 28-15 = 13
So to find B,
A+B+C = 28
B = 28-A-C
B = 28-6-13 = 9
So the line with questioned mark is,
28-9 = 19

Answer:
15 or 3 so B
Step-by-step explanation:
So 5/6 of 18 is 90/6. If you like, you can divide that to simplify and you get 15. Another way to do it is to divide 18 by 6 which gets you 3.
Step by step explanation:
18(5/6) -Reduce the numbers with the GCF (greatest common factor)
3*5 - Multiply the numbers

Point P is the centroid of LMN. Find PN
Answers
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

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

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?
Answers
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

Write an equation of the line passing through point P that is perpendicular to the given line P(6, -3), y
Answers
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]

Some people don't like walking.
Answers
Answer: All people do like walking
It might be more grammatically correct to say "all people like walking", but I wanted to include the "do" in there because we can see how the "don't" flips to "do". The "some" flips to "all" as well.
The negation of a statement is the complete opposite in every way. If a friend makes a claim that some people don't like walking, and you can prove that all people do like walking, then this contradicts your friend. The same can be said in reverse: if your friend claims "all people do like walking", then you can counter back with "some people don't like walking". All it takes is one counter-example to prove the claim "some people don't like walking" to be correct. In terms of logic, the word "some" means "one or more".
What is the measure of x
Answers
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]

In ANOP, NP is extended through point P to point Q,
mZOPQ = (6x – 15)°, mZPNO = (2x + 18)°, and
mZNOP = (2x – 13). What is the value of x?
Answers
Answer:
x = 10
Step-by-step explanation:
Form the information given, we can deduce that:
m<OPQ is an exterior angle of ∆NOP = (6x - 15)°
m<PNO = (2x + 18)° and m<NOP = (2x - 13)° are both interior angles that are opposite to the exterior angle.
Therefore, based on the exterior angle theorem:
m<OPQ = m<PNO + m<NOP
(6x - 15)° = (2x + 18)° + (2x - 13)°
Solve for x
6x - 15 = 2x + 18 + 2x - 13
6x - 15 = 4x + 5
6x - 15 - 4x = 4x + 5 - 4x (Subtraction property of equality)
2x - 15 = 5
2x - 15 + 15 = 5 + 15 (addition property of equality)
2x = 20
2x/2 = 20/2 (division property of equality)
x = 10
