They can make 4 teams and have 4 players that won’t be in a team.

This is because 5*5 is 25 but they don’t have 25 players so you would have to go down which is 4*5=20. Sorry if that’s very confusing but hope that helps!

graph each equation for the interval -360 is less than or equal to x and 360 is greater than or equal to x: y=1/2cos(2x+60)
lianna [129]

Answer:

See graph

Step-by-step explanation:

We want to graph y=\frac{1}{2}\cos(2x+60\degree) on the interval -360\degree \le x \le 360\degree

We need to plot some few points

(-30\degree,\frac{1}{2})

(-15\degree,\frac{\sqrt{3}}{4})

(0\degree,\frac{1}{4})

(15\degree,0)

(30\degree,-\frac{1}{4})

(45\degree,-\frac{\sqrt{3}}{4})

(60\degree,-\frac{1}{2})

(75\degree,-\frac{\sqrt{3}}{4})

(90\degree,-\frac{1}{4})

(105\degree,0)

(120\degree,\frac{1}{4})

(135\degree,\frac{\sqrt{3}}{4})

(150\degree,\frac{1}{2})

This will give us one cycle.

We then use the pattern to complete the graph on the interval

-360\degree \le x \le 360\degree

45% of all 1st graders at Sierra Elementary School are female students. This year there are 54 female 1st graders at Sierra Elem
Anit [1.1K]

Answer:

There are 120 1st graders at Sierra Elementary School this year

Step-by-step explanation:

Let n represent the total number of 1st graders at Sierra Elementary School

Since 45% of all 1st graders at Sierra Elementary School are female students and this year there are 54 female 1st graders, 45% of n is equal to 54

→ n(\frac{45}{100}) = 54

→ 45n = 5400

→ n = 120

For the parallelogram, if m<2=4x-17 and m<4=3x-8, find m<1.
kompoz [17]

Answer:

D. 161°

Step-by-step explanation:

m<2 is congruent to m<4, m<1 is congruent to m<3 by properties of a parallelogram

to find x:

4x-17=3x-8

x-17=-8

x=9

m<4=3(9)-8=19

so, m<4=19°

m<2 =19°

to find m<1:

the interior angles of a parallelogram add up to 360°

360-2(19)=2x

2x=360-38

2x=322

x=161°

m<1=161°

Chloe invests money in an account paying simple interest. She invests $200 and no money is added or removed from the investment.
MissTica

Answer:

2%

Step-by-step explanation:

Chloe's simple interest for 1 year is $4. You can get this by subtracting the amount she invested from the total amount she got after one year.

  • $204 - $200 = $4

Now that we know the simple interest, we can now get the simple interest rate or<em> simple percent interest per year </em>by dividing $4 by $200.

  • $4 ÷ $200 = 0.02

Let's change 0.02 into a percentage.

  • 0.02 x 100 = 2%

This means that every year, her investment will earn a <em>2% simple interest.</em>
