Answer:

Boys x 2 = Girls

Step-by-step explanation:

If there are twice as many girls in school as boys than take the number of boys and multiply that by 2. For example if there are 400 boys in school and there are twice as many girs your equation would, 400 x 2 = 800 girls.

The distance formular is represented as :

d = √(x2 - x1)² + (y2 - y1)²

Let d = distance

The vertical and horizontal coordinates as x and y respectively ;

The square root of the sum of square of the difference between the x and y coordinates ;

Distance = √(x2 - x1)² + (y2 - y1)²

Hence, d = √(x2 - x1)² + (y2 - y1)²

Given:

The compound inequality [tex]2x-3 < 7[/tex] and [tex]5-x \leq 8[/tex].

To find:

The solution for the given compound inequality

Solution:

We have, compound inequality [tex]2x-3 < 7[/tex] and [tex]5-x \leq 8[/tex].

For [tex]2x-3 < 7[/tex],

Add 3 on both sides.

[tex]2x < 7+3[/tex]

[tex]2x < 10[/tex]

Divide 2 on both sides.

[tex]x< 5[/tex]            ...(i)

For [tex]5-x \leq 8[/tex],

Subtract 5 from both sides.

[tex]-x \leq 8-5[/tex]

[tex]-x \leq 3[/tex]

Divide both sides by -1. So, the sign of inequality is changed.

[tex]x \geq -3[/tex]            ...(ii)

Using (i) and (ii), we get the solution of given compound inequality as

[tex]x \geq -3[/tex]  and [tex]x< 5[/tex]

Therefore, the correct option is D.

From both percentages, we can see that -83.3% is greater than -86.67%, hence, −5/6 > −13/15

For us to compare negative fractions, we must know that higher negative fractions are less than the smaller ones

Given the fractions  −5/6 and −13/15

First we will need to write this fractions as percentage:

-5/6 * 100 = -500/6 = -83.3%

-13/15 * 100 = -1300/15 = -86.67%

From both percentages, we can see that -83.3% is greater than -86.67%, hence, −5/6 > −13/15

Answer:

1. 125 cm and 275 cm

Step-by-step explanation:

1. 400 cm in total

  Subtract 150 for the longer stick and you are left with 250 cm.

  Divide 250 cm by 2 because you have two sticks, and you get 125.

  That's how long the shorter stick will be.

  For the longer stick, take the other 125 cm left and add the 150 cm that you subtracted earlier because that's how much longer it is than the shorter stick.

  So... 125 cm for the shorter stick, and 275 cm for the longer one

Answer:

1, 6, 15, 20, 15, 6, 1

Step-by-step explanation:

The binomial expansion of (p + q)⁶ gives 1, 6, 15, 20, 15, 6, 1.

There is always one more extra term for each power;

    (p + q)⁰  =                                      1

    (p + q)¹ =                                   1         1

    (p + q)² =                             1         2           1

    (p + q)³ =                         1         3          3           1

    (p + q)⁴ =                   1          4          6          4             1

    (p + q)⁵ =             1          5          10         10         5              1

   (p + q)⁶ =          1        6           15         20        15            6             1

The above is a paschal triangle and which shows the coefficients of the expanded terms to their power.

====================================================

Explanation:

Check out the diagram below. I recreated the diagram in your textbook, but I added on a few other points and segments.

Point E is the midpoint of segment AB. Segment OE is perpendicular to AB.

Point F is the midpoint of CD. Segment OF is perpendicular to CD.

Right triangle AOE forms with OA = 10 as the hypotenuse (radius of the circle) and AE = 8, since E cuts AB in half.

Use the pythagorean theorem to find that...

a^2+b^2 = c^2

(AE)^2 + (OE)^2 = (OA)^2

8^2 + (OE)^2 = 10^2

64 + (OE)^2 = 100

(OE)^2 = 100-64

(OE)^2 = 36

OE = sqrt(36)

OE = 6

--------------------

Because chord CD is the same length as chord AB, this means the chords are the same distance from the center point O.

So, OE = OF = 6

Since we have rectangle OEPF, the opposite sides are congruent and we can say OF = EP = 6

Now focus on right triangle OEP. Use the pythagorean theorem again

a^2+b^2 = c^2

(OE)^2 + (EP)^2 = (OP)^2

(6)^2 + (6)^2 = (OP)^2

72 = (OP)^2

(OP)^2 = 72

OP = sqrt(72)

OP = sqrt(36*2)

OP = sqrt(36)*sqrt(2)

OP = 6*sqrt(2)

Answer:

14 + 3 + 4(14) - 28 = 45

45 = 45
