MATHEMATICS MIDDLE SCHOOL

A high school graduating class is made up of 462 students. There are 132 more girls than boys. How many boys are in the​ class?

Answers

Answer 1
Answer:

Answer: There are 165 boys

Step-by-step explanation:

Let's call b the number of boys and call g the number of girls in the class.

Then we know that:

There are 462 students. This is:

b + g = 462

We also know that there are 132 more girls than boys, this means that:

g = b + 132

Now we substitute the second equation in the first and solve for b.

b + (b + 132) = 462

2b = 462-132

2b = 330

b = 165

absolute value tells the distance from that point to 0
so it is always positive

we see that from C to D is 2
also
from A to C is 2

it would be from A to C since it is distance from 0 to -2 which is discribed

How do you find the area of a circle? Isn't it π and something?

Answers

Hi there!


You are partially correct on the π symbol, but there's more!


The formula for finding the area of a circle is:


A = π r².


A stands for area, π stands for pi, and r stands for radius. The ² is there because the radius is half as big as the diameter of a circle.


Hope this helps! :D

the powers of 2 that are in the range 2  through 1,000 are 2,4,8,16,32,64,128,256,&512 .what does that  mean and it said find all the powers of 3 that are in range 3 through 1,000 

 

 

im so confused

Answer:

  • the powers of 2 that are in the range 2  through 1,000 are 2,4,8,16,32,64,128,256,&512.

" This means that we are asked to find the value of 2^n for each n belonging to natural numbers.

Now we will stop our approximation when the value exceeds 1000.

i.e. the range is from 2-1000 ".

since the next number after 512 is 512×2=1024 which exceeds 1000. hence our successive approximation will stop at 512.

  • similarly for the powers of 3 i.e. 3^n

We will start writing our approximation and stop when it will exceed 1000.

i.e. 3, 3^2=9,3^3=27,3^4=81,3^5=243,3^6=729

i.e. the sequence is: 3,9,27,81,243,729.

We stopped at 729 because the next number in the series would be:

3^7=2187

which exceeds 1000.
It means you need to find every power of 3 that are in the range of 3-1000 - the power is the number that says how many times you multiply the original number by itself
So 3 to the 1st power is 3 = 3
3 to the 2nd power is 3X3 = 9
3 to the 3rd power is 3X3X3 = 27
And so on... Hope I helped!

Solve A and B

a.g/-4≥17
b.8x+63>127

plz help me quickly!!

Answers

g(-1/4)>=17/(-1/4) g>=-68 8x=64 8x/8=64/8 x=8
A. (g)/(-4) ≥ 17
Multiply by -4 on either sides to cancel out
g ≥ 17

B. 8x + 63 > 127
Take 63 to the other side
    8x > 64
Divide by 8 on either sides to isolate x
    (8x)/(8) > (64)/(8)
    8 and 8 cancels out
    x > 8
