There are 70 students in a school band. 40%are sixth graders,20% are seventh graders and the rest are eighth graders.How many sixth graders are there.

Answers

Answer 1
Answer:

Answer:the number of sixth graders is 28

Step-by-step explanation:

Total number of students in the school band is 70. 40% are sixth graders. 20% are seventh graders and the rest are eighth graders. This means that the percentage of eighth graders is 100 - (40+20) = 100 - 60 = 40%

This means that the number of sixth graders would be 40% of the total number of students in the school band. It becomes

40/100 × 70 = 0.4×70 = 28

Answer:

x>-16

Step-by-step explanation:

First

4> -x/4

switchsides

-x/4<4

then multipy both sides by 4

4(-x/4)<4*4

then multipy bothsides by -1 and reverse the inequality

(-x)(-1)> 16(-1)

Nellie is analyzing a quadratic function f(x) and a linear function g(x). Will they intersect?

Answers

Answer: yes choice B

Step-by-step explanation:

g(x) has -5 slope

y - g(-1) = -5(x +1)

y -5 = -5x -5

y = -5x

f(x) = xx/2 +2

Xx/2 +2= -5x

Xx/2 +5x +2 = 0

Xx + 10x +4 =0

Solutions: -5 + root(100 -16)/2

And -5 - root(84)/2

Both intersection look like in negative x values

y= 15x+30

Step-by-step explanation:

Find slope using 2 points. Y intercept is where the graph intersects the y axis and you can see it intersects at 30

Y=15x + 30 :) hope this helps and all best of luck for your math

= -120 (Ans)

Answer:

-120

Step-by-step explanation:

lots of approaches here

suggest saying that there are 3 (odd) number of negative signs

so the answer is negative (-)

5*4 = 20

20*2 = 40

40*3 = 120

we determined that the answer has to be negative

-120

Choose the equation of the horizontal line that passes through the point (-2,-1). A.) y = -1

B.) y = -2

C.) x = -2

D.) x = -1

Answers

Answer:

  A.)  y = -1

Step-by-step explanation:

The equation of a horizontal line is ...

  y = constant

To make that line go through the point (x, y) = (-2, -1), the constant must match the y-coordinate of the point: -1.

  y = -1

I can’t figure out how to solve this, can someone help? 5m-12=m

Answers

Answer:

m = 3

Step-by-step explanation:

5m - 12 = m

subtract 5m from both sides

5m - 5m - 12 = m - 5m

simplify

-12 = -4m

divide both sides by -4

-12 / -4 = -4m / 4

simplify

3 = m

hope this helps :)
