Answer:

  a:  12^18

Step-by-step explanation:

The applicable rule of exponents is ...

  (a^b)(a^c) = a^(b+c)

__

All of the bases are the same in this expression, so the exponents add:

  12^3 * 12^9 * 12^4 * 12^2 = 12^(3+9+4+2) = 12^18 . . . . matches choice A

The mean absolute deviation for the class is,  10.96

Data refers to the elements that make up persons, things, events, and ideas. It could be an integer, a title, or anycast. Data must be tabulated after collection in order to study their prominent characteristics. The presentation of data is the name given to such a configuration.

Bar Chart, Histogram, Line Graph, Pie Chart, Frequency Distribution Table.

Given,

Student Score

Tom 89

Jon 72

Sue 98

Jill 78

Zeke 62.

Therefore, The mean of the data set is,

= 399/5

= 79.8.

Now,

Total of data value - mean = 54.8

54.8/5

= 10.96

Answer: 3 hours

Step-by-step explanation:

25 x 3 = 75

90 - 75 = 15 ( aka 1 service call)

Hope this helps!

Answer:

3 hours

Step-by-step explanation:

$25(3 hours)=$75

$75+$15=$90

Answer:

x = -3

Step-by-step explanation:

The equation of any linear function is y = mx + c, where m is the gradient and c is the y-intercept

The equation of the function is y = -x + 4

The gradient is negative one (hence 1x) and the y-intercept is 4

We need to find what x equals when the y = 7

7 = -x + 4

Rearrange

7 - 4 = -x

-x = 3

x = -3

Answer:

[tex]d = 10[/tex]

Step-by-step explanation:

[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Simply plug in the 2 coordinates into the distance formula to find distance d:

[tex]d = \sqrt{(-2-6)^2+(4-(-2))^2}[/tex]

[tex]d = \sqrt{(-8)^2+(4+2)^2}[/tex]

[tex]d = \sqrt{64+(6)^2}[/tex]

[tex]d = \sqrt{64+36}[/tex]

[tex]d = \sqrt{100}[/tex]

[tex]d = 10[/tex]

Answer:

10 units

Step-by-step explanation:

( x1, y1) =A(6,-2)

(x2, y2) =B(-2,4)

Using distance formula,

AB ^2 = (x2-x1) ^2 +(y2-y1) ^2

=(-2-6)^2 +(4+2)^2

=64+36

=100

Therefore, AB=10 units

Answer: image below is the answer

Step-by-step explanation:

$1.80 + $1.20 = $3.00  <  $1.86 + $1.23  <  $2.00 + $1.50 = $3.50

Double these supplies will cost between 2 × $3.00 and 2 × $3.50.

2 x $1.23 = $2.46

Think about more items Kira could buy so that her total cost is more than $4 but less than $6.

$1.80 + ($1.10 x 2) = $4.00  <  $1.86 + ($1.23 x 2)  <  $2.00 + ($1.25 x 2) = $4.50

Think about more items Ida could buy so that her total cost is more than $8 but less than $9.

Answer:

3 hours

Step-by-step explanation:

Let the number of hours worked = x

Delicious Doing caterers events at a flat rate $500 plus $100 per hour after the first 2 hours.

$500 + $100 × x

500 + 100 × 1

After the first 2 hours = $500 + $100

= $600

After the first 3 hours = $500 + $100 × 2

= $700

Cathy's Catering has a flat rate of $620 per event plus $70 per hour after the first three hours.

$620 + $70 × x

620 + 70x

After the first 3 hours

= $600 + $70

= $670

What is the most amount of hours you could hire Cathy's Catering for and it cost less than Delicious Doings?

The Inequality is given as:

Cathy's Catering for < Delicious Doings

620 + 70x < 500 + 100x

Collect like terms

620 - 500 < 100x - 70x

120 < 30x

120/30 < x

4 < x

Therefore, the most amount of hours the most amount of hours you could hire Cathy's Catering for and it cost less than Delicious Doings is 3 hours

Answer:

y = 2x

Step-by-step explanation:

Coordinates:

(1, 2)

(0, 0)

Slope = 2/1 = 2

y = mx + b

2 = 1 * 2 + b

2 = 2 + b

b = 0

So:

y = 2x

Answer: (66/11)^3-6*8 = 168

              10/7+28-51/2 = 23.93

Step-by-step explanation:

First set:

(66/11)^3-6*8

(66/11)=6

(6)3-6*8

216-6*8

6*8=48

216-48= 168

Second Set:

10/7+28-51/2

= 206/7-5.5

Answer: 55 degrees / Acute angle.

Step-by-step explanation:

The angle is less than a right angle, bent forward so it's less than 90 degrees, meaning it's an acute angle.

Answer:

w = 90/65 (125)

Step-by-step explanation:

Since you are trying to find how much Gabriel can type in 125 seconds, you have to find how much he can type in 1 second. Then you can multiply by 125 to get your answer!
