The area of an 15cm wide rectangle is 360 cm^2 what is the length

Answer:

x = 9

Step-by-step explanation:

2X + 10=28

Subtract 10 from each side

2X + 10-10=28-10

2X = 18

Divide each side by 2

2X/2 = 18/2

x = 9

Answer:

X=9

Step-by-step explanation:

28-10=18

2 x 9= 18

Answer:

3,21 is

2,21 is not a proper ordered pair.

Step-by-step explanation:

Remark

It's not a solution

You can either use the x value to find out the proper y value

or

You can use the y value to find out the proper x value

Proper y value

Let x = 2

y = 7*2

y = 14

So the proper y value given that x = 2 is 14.

Proper x value

Let y = 21

21 = 7x                    Divide both sides by 7

21/7 = 7x/7

3 = x

But (2,21) is not a solution. (3,21) is.

Answer:

4

Step-by-step explanation:

2 · 4 = 8

8 + 4 = 12

the value of x is 4

Answer:

0.6

Step-by-step explanation:

Answer:

-2(4-1)

Step-by-step explanation:

Do parentheses first because of PEMDAS. That means 4-1 equals 3. Then take -2 and times it by the 3 to get -6.

Answer:

The answer would be -2(4-1)

Step-by-step explanation:

-2 multiplied by 4 is -8

-2 multiplied by -1 is 2

you then add -8 and 2 which equals -6

Answer:

x=81

Step-by-step explanation:

all triangles = 180 degrees

180 - 18 = 162

162/2 = 81

81 is your answer

Answer:

81 Degrees

Step-by-step explanation:

These are the same number which means all you have to do is remember that triangles are 180 degrees total and subtract out the 18 and you get 162 which you then divide by 2.

Answer:

1350

Step-by-step explanation:

multiply

Answer:

x = 24

Step-by-step explanation:

Ok so basically the angles shown are vertical angles

One of the properties of vertical angles is that they are congruent

That being said we would use this equation to solve for x

120 = 5x

then you would solve for x

*isolate the variable*

step 1 divide each side by 5

120/5=24

5x/5=x

we're left with x = 24

Answer:

D) 476 ft²

Step-by-step explanation:

12x14=168

(25+31)/2=28

28x11=308

308+168=476

Answer:

Arithmetic

Step-by-step explanation:

Sequences:

A sequence is called arithmetic if the difference between consecutive terms is the same.

A sequence is called geometric if the quotient between consecutive terms is the same.

In this question:

28 - 22 = 22 - 16 = 16 - 10 = ... = 6

Difference is always 6, that is, each term is the previous one subtracted by 6. So the sequence is arithmetic.

Answer:

$13.64

Step-by-step explanation:

you need about 1853 sheets of paper which is

1853 ÷ 500, or 3.706 reams

if 1 ream costs $3.68 then 3.706 reams costs 3.706 × 3.68 or $13.64

Answer:

[tex]P(C\ or\ D) = 1[/tex]

Step-by-step explanation:

Given

[tex]P(C) = \frac{3}{7}[/tex]

[tex]P(D) = \frac{4}{7}[/tex]

Required

[tex]P(C\ or\ D)[/tex]

Since the events are mutually exclusive, then:

[tex]P(C\ or\ D) = P(C) + P(D)[/tex]

So, we have:

[tex]P(C\ or\ D) = \frac{3}{7} + \frac{4}{7}[/tex]

Take LCM

[tex]P(C\ or\ D) = \frac{3+4}{7}[/tex]

[tex]P(C\ or\ D) = \frac{7}{7}[/tex]

[tex]P(C\ or\ D) = 1[/tex]

Answer:

  B.  1.80

Step-by-step explanation:

The change of base formula can be used.

  [tex]\log_5(18)=\dfrac{\log{18}}{\log{5}}\approx\dfrac{1.25527}{0.69897}\approx1.7959\\\\\boxed{\log_5{18}\approx1.80}[/tex]

Answer:

[tex]\frac{5}{3}[/tex]

Step-by-step explanation:

let blank be O

[tex]\frac{5}{6} +O=\frac{5}{2} \\[/tex]

[tex]O=\frac{5}{2} -\frac{5}{6} =\frac{15}{6} -\frac{5}{6} =\frac{10}{6} =\frac{5}{3}[/tex]

Answer:

a₇ = 16992.84

Step-by-step explanation:

Given that,

a₁ = 11, r = 3.4 and n = 7

The geometric sequence is given by :

[tex]a_n=a_1\cdot r^{n-1}[/tex]

Put all the values,

[tex]a_7=11\times (3.4)^{7-1}\\\\=11\times (3.4)^6\\\\=16992.84[/tex]

So, the seventh term is equal to 16992.84.

Answer:

The slope of the line is 1

Step-by-step explanation:

the formula for slope is

y¹-y²

-----

x¹-x²

y¹ and x¹ can be either of the points.

So let's make it (6,5)

This means that y² and x² will be (8,7)

The equation will be

5-7d -2

----- = ---

6-8 -2

which can be simplified to 1 by divied both by -2
