Find the scale factor,and find the unknown side lengths.<br> Help if you can please
Burka [1]

Step-by-step explanation:

Solution,

since two of these triangle are similar so,

i) LK/LJ=MN/NO

or,j/8=18/12

or,j=18×8/12

.°. j = 12m

ii)JK/JL=MO/NO

or,10/8=n/12

or,120/8=n

.°.n=15m

Which of the following is a solution of the system 2x + y = 9 and 3x + 5y = 19.​
Nezavi [6.7K]

2x+y=9

3x+5y=19

I will do this problem in 2 ways. I.)Substitution II.)Elimination

Solution I.) Substitution

We can subtract 2x from both sides in the first equation.

y=9-2x

Now we can substitute the y in the second equation with 9-2x

3x+5(9-2x)=19

-7x+45=19

-7x=-26

x=26/7

y=9-2(26/7)=11/7

Solution II.)Elimination

We can multiply both side of first equation by 5 to get a 5y in both equations.

10x+5y=45

Now because both are positive 5y we just need to do simple subtraction of the 2 equation, each side respectively.

(10x+5y)-(3x+5y)=45-19

7x=26

x=26/7

2*26/7+y=9

y=11/7

Ultimately you get the same answer, both are viable methods, some problems are faster with one method but I recommend mastering both since they are very useful.

I WILL GIVE YOU BRAINLY PLSS <br><br><br> Worth 19 points
Pavel [41]

Answer:

942

Step-by-step explanation :

so your d is 300 so your r = 300/2= 150  

a=3.14*r*r= 3.14*150*150= 70650

c= 3.14*d= 3.14*300= 942

OR

The curved surface area of solid cylinder is  

 

As we are given that:

Diameter of solid cylinder = 8 cm

Length or Height o solid cylinder = 140 cm

Formula used to calculate the curved surface area of cylinder is:2n x h

Curved surface area of cylinder =2r x h  

where,

r = radius of cylinder

h = height or length of cylinder

Radius of cylinder =  daimeter

Now putting all the given values in above formula, we get:

Curved surface area of cylinder =  2x 22/7 x 140cm

Curved surface area of cylinder = 3520cm^{2}

Therefore, the curved surface area of solid cylinder is3520cm^{2}
