HELP PRETTY PRETTY PLEASE!?!?

Answer:

9b-12<9b+8

Step-by-step explanation:

b<20

Answer:

perimeter of rectangle=2(l+b)

=2(13.5+7)

=2*20.5

=41

area of rectangle=l*b

=13.5*7

=94.5 inch^2

area of triangle=1/2*b*h

=9.48*4.2/2

=19.90

=19.9

perimeter of triangle=a+b+c

=(4.46+9.48+10) inches

=23.94 inches^2

to find x

7x+2=3x+18

7x-3x=18-2

4x=16

x=16/4

x=4

perimeter of rectangle=2(l+b)

=2(7x+2+12.5)

=2(7*4+12.5)

2*40.5

=81

perimeter of triangle=1/2*b*h

=7.3*6.3/2

=45.99/2

=22.99

=23 mm^2

area of a triangle=a+b+c

=s+s+s

=7.3+7.3+7.3

=21.9 mm^2

Radius=14 inc

diameter=radius*2=28 inc

circumference=2πr

=2*3.14*14

=87.92

area of ciecle=π[tex]r^{2}[/tex]

=3.14*(14)^2

=3.14*196

=615.44

Answer:

  42.1 cm

Step-by-step explanation:

The long arc is 265°/360° = 53/72 of the circumference of the circle. Its length is ...

  arc length = 53/72C = 53/72(2πr) = 53π/36(9.1 cm) ≈ 42.1 cm

there is no table.  Sorry!

Step-by-step explanation:

Answer:

15ways

Step-by-step explanation:

This question bothers combination

Combination has to do with selection

Given

Total number of teams  = 6

champion and runner up = 2

number of ways is expressed as 6C2

6C2 = 6!/(6-2)!2!

6C2 = 6!/4!2!

6C2 = 6*5*4!/4!*2

6c2 = 30/2

6C2 = 15

Hence the number of ways they can be selected is 15ways

Answer:

[tex] \frac{4}{?100} \times \frac{2000}{?1} = 80 \\ \\ 2000 + 80 = 2080 \\ \\ 2080 \times 15 = 31200 [/tex]

Answer: 7.3

Step-by-step explanation:

you plug in y=a(1/2) ^t/h

To 9300 = 3300 (1/2)^t/h

Answer:

If you're timed then I would say,

Yes this is a random study because the problem specifically states that the survey samples were randomly selected from populations.

I think that is the answer! However, if you have time I would wait for another person to answer as well because I'm terrible at statistics :(

Answer:

No, its nat a random sample

Step-by-step explanation:

Its not a random sample because you have already selected two populations (the two largest US cities) which may or may not be representative of the vast majority of the country.

Hope this helps:)

Answer:

population=12780

Step-by-step explanation:

7% of 9000 is 630

630 times 6 is 3780

9000 plus 3780 is 12780

Answer:

1.6+3 x 4 -2/2

1.6+12-2/2

1.6+12-1

13.6-1

12.6

hope this helps

have a good day :)

Step-by-step explanation:

The expression 1.6 + 3 x 4 - 2 divided by 2  simplifies to 12.6.

Use the concept of mathematical expression defined as:

Using operations like addition, subtraction, multiplication, and division, a mathematical expression is defined as a group of numerical variables and functions.

The given expression is:

1.6 + 3 x 4 - 2 divided by 2

We know the BODMAS rule,

According to this rule for a mathematical expression, we have to follow these operations in the following order:

1: Bracket opening

2: Division

3: Multiplication

4: Addition

5: Subtraction

Now applying this rule in the given expression,

1.  1.6 + 3 x 4 - 1

2. 1.6 + 12 - 1

3. 13.6 - 1

4. 12.6

Hence,

The expression 1.6 + 3 x 4 - 2 divided by 2  simplifies to 12.6.

Answer:

180

Step-by-step explanation:

225 X .80 (100%-20%)

Answer:

So Joyce earns $700 and Marianne earns $900 per week. and $900=$200+$700. A slightly different approach is to say, if Marianne didn't earn 200 more than Joyce, then the combined income would be $200 less or $1600-$200=$1400. Now they both earn the same so each would get half of $1400 or $700.

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Because B and D were both according to the Mean, and that is the same in the table so we can cross those out. And C is wrong because there are not less of a variation but more variation. So A would be your answer!

Answer:

acute angles and an obtuse angle

Step-by-step explanation:

There are different types of triangle. We have;

Right angled

Obtuse triangle

isosceles triangle etc

Angles of an obtuse triangle is made up of two acute angles are an obtuse angle.

hence the two angles that can make up a triangle out of this three is acute angles and an obtuse angle since this two angles literally form an obtuse triangle

Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of small hat purchased, y represent the number of medium hat purchased and z represent the number of large hat purchased.

Since a total of 47 hats where purchased,  hence:

x + y + z = 47    (1)

Also, he spent a total of $302, hence:

5.5x + 6y + 7z = 302     (2)

He purchases three times as many medium hats as small hats, hence:

y = 3x

-x + 3y = 0    (3)

Represent equations 1, 2 and 3 in matrix form gives:

[tex]\left[\begin{array}{ccc}1&1&1\\5.5&6&7\\-3&1&0\end{array}\right] \left[\begin{array}{c}x\\y\\z\end{array}\right] = \left[\begin{array}{c}47\\302\\0\end{array}\right] \\\\\\\\ \left[\begin{array}{c}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}1&1&1\\5.5&6&7\\-3&1&0\end{array}\right] ^{-1} \left[\begin{array}{c}47\\302\\0\end{array}\right] \\\\\\ \left[\begin{array}{c}x\\y\\z\end{array}\right] = \left[\begin{array}{c}6\\18\\23\end{array}\right][/tex]

Therefore he purchases 6 small hats, 18 medium hats and 23 large hats

Answer:

Let x represent the number of small hat purchased, y represent the number of medium hat purchased and z represent the number of large hat purchased.

Since a total of 47 hats where purchased,  hence:

x + y + z = 47    (1)

Also, he spent a total of $302, hence:

5.5x + 6y + 7z = 302     (2)

He purchases three times as many medium hats as small hats, hence:

y = 3x

-x + 3y = 0    (3)

Therefore he purchases 6 small hats, 18 medium hats and 23 large hats

Answer:

????

Step-by-step explanation:

Answer:

Step-by-step explanation:

Property of the perpendicular lines,

If the two lines [tex]L_1[/tex] and [tex]L_2[/tex] having slopes [tex]m_1[/tex] and [tex]m_2[/tex] are perpendicular to each other,

Then [tex]m_1\times m_2=-1[/tex]

Equation of line [tex]L_1[/tex] → y = 3x + 5 ------(1)

Equation of line [tex]L_2[/tex] → 6y + 2x = 1 ------- (2)

Slope of line [tex]L_1[/tex],

[tex]m_1=3[/tex]

Slope of line [tex]L_2[/tex],

6y + 2x = 1

6y = -2x + 1

[tex]y=-\frac{2}{6}x+\frac{1}{6}[/tex]

[tex]y=-\frac{1}{3}x+\frac{1}{6}[/tex]

Therefore, [tex]m_2=-\frac{1}{3}[/tex]

By using the property of perpendicular lines,

[tex]m_1\times m_2=3\times (-\frac{1}{3} )[/tex]

              [tex]=-1[/tex]

Therefore, both the lines are perpendicular.
