Miss Tamika just started an art class. She had 10 children enrolled for the first class. · Before she began the art lesson, she told each of the children to shake hands with ! each of the other children and introduce I themselves. Miss Tamika did not include i herself because she had already met each i of the children. How many handshakes were there between all of the children?​

Answer:

7. x = 88

8. x = 59

Step-by-step explanation:

You're probably trying to equal 180° because that's what the triangle should equal so

7. 48° + (88° - 44°) + 88° = 180°

8. 73° + (59° - 11°) + 59° = 180°

I hope this is right :,)

Answer:

Yes

Step-by-step explanation:

Answer:

The cylinders volume is 113.04 cubic inches

Step-by-step explanation:

The volume of a cylinder can be represented by the formula : V = π*r^2*h

So, now that we have the formula, we can simply plug in the values, and we have the volume of the cylinder.

V = π * 2^2 * 9

V = π * 4 * 9

It says to use 3.14 as π.

V = 3.14 * 4 * 9

V = 113.04

The cylinders volume is 113.04 cubic inches

Answer:

  4 miles per hour

Step-by-step explanation:

The given relations allow us to write two equations.

__

The downstream speed is the sum of the canoe speed and the stream speed:

  6 = c + s

The upstream speed is the difference of the canoe speed and the stream speed:

  2 = c - s

Adding these two equations, we get ...

  8 = 2c

  4 = c . . . . . divide by 2

The canoe speed in still water is 4 miles per hour.

Hey there!

x + 19 + 7x + 9 = 180°

1x + 19 + 7x + 9 = 180°

8x + 28 = 180°
SUBTRACT 28 to BOTH SIDES

8x + 28 - 28 = 180° - 28

SIMPLIFY IT!
8x = 180 - 28

8x = 152

DIVIDE 8 to BOTH SIDES

8x/8 = 152/8

SIMPLIFY IT!
x = 152/8

x = 19

Therefore, your answer should be:

x = 19

Good luck on your assignment & enjoy your day!

Answer:

25

Step-by-step explanation:

x^2 + 10x + 25   = (x+5)^2

Given:

5:8 and 3:7 = 45:X

Explanation:

15:56 = 45:x

15x. = 2520

X=2520/15

x= 168

Conclusion:

Thus the value of x is found to be 168.

5:8 and 3:7=45:x

15:56 = 45:x

Product of means. = product of extremes

15x. = 2520

X=2520/15

x= 168

Answer: n= 15+58 = 73

Step-by-step explanation: Add pages for the week and weekend

Answer:

Step-by-step explanation:

HadizaReadingWeekly= 15 * Weekdays + 58 for Weekend

HRW=15*WD + 58

H =15*D +58

where H = HadizaReadingWeekly

D = days of the week (5)

then

H = 15*5 +58

H = 75 + 58

H = 133

Hadiza read 133 pages this week  

Answer:

y = x/2

Step-by-step explanation:

y = -x has a negative slope so cross this one out.

y = 2x has a steeper slope that would be above the black line so cross this one out

y = 0.001x has a slope that acends very slowly so cross this one out.

y = x/2 is the best match.

Some terminology:

 ⇒what is the slope

    ⇒ is the steepness of the line

        ⇒calculated by dividing the rise over the run

           ⇒ rise is the change in the y-direction

               ⇒ run is the change in the x-direction

                  ⇒look at the diagram I attached

 ⇒ how to find the slope in a linear equation

     ⇒look to the coefficient of the 'x' variable

        ⇒ that is the slope

      Ex. For the line y = x, the slope is 1

⇒A line with a positive slope rises from left to right while a line with a    negative slope falls from left to right.

   Ex. y=x has a positive slope and thus is rising

We want to find the equation that could represent the blue line

   ⇒ let's look into each equation and see whether they work or not

First case: [tex]y = -x[/tex]

  ⇒The equation given has the line falling, when the graph in the    

  equation is rising

       ⇒ not the answer

Second case: [tex]y=2x[/tex]

   ⇒ the equation given has the line that has a bigger slope than the

  the equation shown, which has a smaller slope than y = x

       ⇒ not the answer

Third case: [tex]y=\frac{1}{2}x[/tex]

    ⇒ the equation given fits the requirement of having a rising slope that

    is smaller than y = x

        ⇒ is a possible answer

Fourth case: [tex]y = 0.001x[/tex]

     ⇒ the equation given has a slope that is almost horizontal when the

     line shown in the graph doesn't

          ⇒ not the answer

Thus after examing all the choices:

   ⇒ Answer: [tex]y=\frac{1}{2}x[/tex]

Answer:

the answer for the first one is 141

and the answer for the second is 48

Answer:

First: -1628

Second: -16

Step-by-step explanation:

For the first problem, start by rewriting the equation by plugging in h and g as (4n-3)(-4n-4)

By FOILing this, you’ll end up with -16n^2-16n+12n+12
-16n^2-4n+12

Now you can plug in n, which is -10:

-16(10)^2-4(10)+12

-1600-40+12

-1628

For the second question, you’ll be plugging f(-2) into g, but I’ll leave -2 as n for simplicity until the end

g(n)=n^2+2n

f(n)=2n-4

g(n)=(f(n))^2+2(f(n))

(2n-4)^2+2(2n-4)

(4n^2-16n+16) + (4n-8)

4(-2)^2-16(-2)+16+4(-2)-8

16-32+16-8-8

Answer:

C, 60 degrees

Step-by-step explanation:

Right Triangle, with a 30 degree angle:
Given degrees:
90 (Right Triangle)
30

90+30 = 120
180-120 = 60

180 Degrees total in a triangle, you simply subtract the measure you have to fidn the third one.

Answer:

The measure of the third angle is 60°.

Step-by-step explanation:

We are given a right triangle that has a 90 degree and two other angles that are unknown.

Since one known angle is 90° and another angle given is 30° then the third angle must be 60°. All triangles must add up to 180°.

180° - 90° -  30° = 60°.

Here is an image of the demonstration/explaining types of triangles.

Step-by-step explanation:

Answer:

86,800,000

________________________________________________________

Remember the order of operations,

Go from top to bottom as most to least important. Start with exponents, the tiny floating numbers. 10 to the power of 5 is the same as 10 times itself 5 times, or increasing the zeros 5 times.

[tex]10^5 = 100,000[/tex]

Next, multiply by 868.

[tex]100,000 * 868 = 86,800,000[/tex]

Answer:

9x^2 - 36x + 35.

Step-by-step explanation:

One would be (x - 5/3)(x - 7/3)   <------ in factor form.

Getting rid of the fractions by multiplying each term by 3:

= (3x - 5)(3x - 7)

Converting to standard form

= 3x*3x -7*3x - 5*3x + 35

= 9x^2 - 36x + 35.

Answer:

Acute

Step-by-step explanation:

The angle is 5 degrees.

Acute angles are angles between 0-90

Right angles are angles measuring 90 degrees

Obtuse angles are angles between 90-180

Therefore this angle is Acute

Answer: √58

Step-by-step explanation:

[tex]\begin{aligned}&\left(x_{1}, y_{1}\right)=(-2,-3) \\&\left(x_{2}, y_{2}\right)=(1,4) \\&\text {The distance between two points is given by,} \\&d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}} \\&d=\sqrt{(4+3)^{2}+(1+2)^{2}} \\&d=\sqrt{7^{2}+3^{2}} \\&d=\sqrt{49+9} \\&\bold{d=\sqrt{58}}\end{aligned}[/tex]

Therefore, distance between the two points is √58 and the number that goes under the radical symbol is 58
