pleaseee help meeee 42 + 1 x 4

Consider the below below figure is attached with this question.

Given:

M is the midpoint of LN.

N is the midpoint of MO.

To prove:

LM=NO​ (instead of LM=MO).

Solution:

It is given that, M is the midpoint of LN. So,

[tex]LM=MN[/tex]             ...(i)

N is the midpoint of MO. So,

[tex]MN=NO[/tex]             ...(ii)

Using (i) and (ii), we get

[tex]LM=NO[/tex]

Hence proved.

Answer:

[tex]\large \boxed{\sf h= \frac{S-2\pi r}{2\pi r} }[/tex]

Step-by-step explanation:

The surface area of a cylinder:

[tex]S=2\pi r h + 2\pi r[/tex]

Solve for height h

Subtract 2πr  from both sides

[tex]S-2\pi r=2\pi r h[/tex]

Divide both sides by 2πr

[tex]\displaystyle \frac{S-2\pi r}{2\pi r} = h[/tex]

Answer:

[tex]\huge\boxed{(2,4)}[/tex]

Step-by-step explanation:

2x + 5y = 16 ------------------(1)

-5x -2y = 2   ------------------(2)

Multiplying (1) by 5

5(2x+5y) = 16*5

10x+25y = 80 ----------------(3)

Multiplying (2) by 2

2(-5x-2y) = 2*2

-10x - 4y = 4 -----------------(4)

Adding Eq. (3) and (4)

10x + 25y -10x -4y = 80 + 4

25y - 4y = 84

21y = 84

Dividing both sides by 21

y = 4

[tex]\rule[225]{225}{2}[/tex]

Now, Putting y = 4 in Eq. (1)

2x + 5(4) = 16

2x + 20 = 16

2x = 20 - 16

2x = 4

Dividing both sides by 2

x = 2

[tex]\rule[225]{225}{2}[/tex]

Ordered Pair = (x,y) = (a,b) = (2,4)

[tex]\rule[225]{225}{2}[/tex]

Hope this helped!

Answer: 1,3 on edg 2020

Step-by-step explanation:

Answer:

1st and 3rd

Step-by-step explanation:

EDG correct :)

Step-by-step explanation:

a. y = 2 + 4.3(-6)

y= 2- 25.8

y= -23.8 or y= -24

b. y= (9-3)2

18-6=12

c. y= 3.5-2

y= 1.5

d. y= 5(-2) - 4

y= -10-4

y= -14

Answer:

65.8

Step-by-step explanation:

(2.6*4.7)/2=6.11

11*4.7=51.7

(4.7(17-(2.6+11)))/2=7.99

6.11+51.7+7.99=65.8

Answer:

2/5

Step-by-step explanation:

Picking 4 cards out of 10, and as a fraction, it would be 2/5

Answer:

2/5 chance

Step-by-step explanation:

Well there 10 letters and only 4 letters are between Q and t (Q,R,S,T) so 4/10 simplified is 2/5.

Answer:

11

Step-by-step explanation:

20-[(x-19)+(x+17)]

=20-2x+2

=22-2x

As AB+BC=AC, 22-2x=0.

Thus 2x=22

x=11

it should be right

Numbers are already in ascending order

So the 5 numbers are

Answer:

Step-by-step explanation:

10q+3q+5=2(q-3)  Given

13q+5=2q-6    Simplify both sides

-2q on both sides

11q+5=-6

-5 On both sides

11q=-11 Divide by 11

q=-1

Answer:

the answer is b

Answer:

-11

Step-by-step explanation:

plug -3 in x values.

h(-3) = -3^2 -2

=-11

Answer: h(-3) = 7

Explanation: If h(x) = x² - 2, then h(-3) = (-3)² - 2

which simplifies to 9 - 2 or 7.

Remember to always use parenthses when

substituting your given value in for x.

Answer:

The answer, if it is addition, would be 4 + 4/5w

Step-by-step explanation:

(x - 5)(x - 4)

Hi there !

x² - 9x + 20​ =

= x² - 4x - 5x + 20

= x(x - 4) - 5(x - 4)

= (x - 5)(x - 4)

Good luck !

Answer:

M(6,3)

Step-by-step explanation:

Find the average of your x1 and x2 and your y1 with your y2.

Don't change which ordered pair is 1 or 2.

so:

U(2,3)

V(10,3)

M(x,y)

x= (2+10)÷2=(12)÷2=6       X=6

y=(3+3)÷2=6÷2=3             Y=3

Answer:

y = -5/3x + 57/3

Step-by-step explanation:

Solve 5x = 1 -3y for y

so 3y = -5x + 1 divided by by 3

y = -5/3x +1/3

Since its parallel it has the same slope

To find the y-intercept you need to move 9 to 0

so the intercept = 12/3 + 45/3 = 57/3

Answer:

Step-by-step explanation:

y + 6 = 12(x - 7)

y + 6 = 12x - 84

y = 12x - 90

1. Summarize the data given.

You know that you made $51 in just one day. You charge $9 for going to their house, plus $6 hours for raking.

9 + 6x = 51

X = The Hours Spent Raking

2. Turn the equation so then 6x is by itself.

9 + 6x = 51

-9             -9

6x = 42

3. Remove the number, so x remains by itself.

6x = 42

/6    /6

x = 7

So that means, you spent 7 hours raking leaves on the day I made 51 dollars.

Answer:

You spent 7 hours.

Step-by-step explanation:

First add 9 and 6 together which is 15 and then you continue to add 6 until you reach 51. I added 6 to my sum 7 times .

Answer:

The steepness of the graph will decrease when the width of the bottle is increased.

Step-by-step explanation:

We are told that a bottle with a height vs. volume graph is created asthe bottle is consistently filled with liquid

Now, from initial conditions, the bottle will be empty and immediately we start putting liquid into the bottle, the graph of height vs volume starts.

Now, this height(H) represents the height of the liquid in the bottle while volume(V) is the volume of liquid in the bottle.

Now, we want to find the correlation between the width of the bottle and the steepness of the graph.

Thus, if we are to increase the width of the bottle, it means we are also increasing the capacity of the bottle which is the volume of the bottle.

What this means is that for us to get to the same height(H) before the increase in bottle width, we will need to pour in a larger volume of liquid(V').

If the extra amount of liquid to be poured is v, then the new volume that will get the liquid to the initial height(H) is;

V' = V_initial + v

The implication of this is that the slope of the graph will decrease.

Thus in terms of the question, the steepness of the graph will decrease when the width of the bottle is increased.
