Which number line best shows the position of square root of 7?

Answers

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

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

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

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

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]

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".

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

48

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]
