Answer: <u><em>No. of students in 9th grade = 150 </em></u>

<u><em>No. of students in 10th grade = 300</em></u>

Step-by-step explanation: Total No. of Students = 450

∴No. of students in 9th grade = 1/3 of 450

I.e. = 1/3 × 450 = 150 students in 9th grade.

<em>Let the No. of students in 10th grade be 'x'</em>

x = 450 - 150 = 300 students in 10th grade.

∴No. of Students in 9th grade = 150 students

∴No. of Students in 10th grade = 300 students

Which of the following graphs represents a function? If you don’t know then please don’t write “i don’t know” or “I can’t help w
Vadim26 [7]

Answer:

B. x

Step-by-step explanation:

The answer would be graph x. A function must be that one x value should only have one y value. graph w doesn't work since when you plug in 0, you get two y's. same thing with z. Y doesn't work since at x value of 3, it curves back so x value 2 has 2 y's. X is the only one that each x value has only one y.

Two concentric circles are of radii 5 cm and 3 cm. Determine the length of the chord of the larger circle which touches the smal
tangare [24]

Answer:

Let O be the common center of two concentric circles and let AB be a chord of larger circle touching the smaller circle at P join OP

Since OP is the radius of the smaller circle to any chrod of the circle bisects the chord.

∴ AP=BP

In right ΔAPO we have

OA  

2

=AP  

2

+OP  

2

⇒25−9=AP  

2

 

⇒AP  

2

=16⇒AP=4

Now AB=2,AP=2×4=8[∵AP=PB]

hence the length of the chord of the larger circle which touches the smaller circle is 8cm.

Some one help me!,!!,!,!!!!!
ella [17]

Answer:

See below in bold.

Step-by-step explanation:

The angle below and to the right of 30 degrees = 90-30 = 60 degrees,.

< EAC + 5x + 6x = 180

But m < EAC = the angle found in first line so its 60 degrees.

S0 3x + 5x + 60 = 180

8x = 120

x = 15

So m < CAB = 75 degrees and m < BAH = 45 degrees.

Finally the m  <  on top left = 90 degrees.

Use the zero product property to find the solutions to the equation 2x + x-1-2.
Mazyrski [523]

Answer:

im sorry this isnt an answer but it won't let me comment this correction

Step-by-step explanation:

you didnt rewrite the images back into the problem as text so i did it for you so people can answer the problem better with the fractions included.

Use the zero product property to find the solutions to the equation 2x2 + x – 1 = 2.

x = -1/2 or x = 2

x = –2 or x = 1/2

x = -3/2 or x = 1

x = 1 or x = 3/2
