Use parentheses to show two ways of grouping the numbers in 12 • 8 • 25. Tell which expression you think would be easier to simplify, and why. Then simplify the expression.

Answers

Answer 1

Step-by-step explanation:

First no. is 12

Second no. is 8

Third no. of 25

Way 1 of grouping the numbers,

(12×8)×25

We can use associative law of multiplication as follows :

(a×b)×c = a×(b×c)

(12×8)×25 = (96) × 25

= 2400

Way 2,

12×(8×25) = 12 × 200

= 2400

Way 2 is easier to simplify because when we multiply 8 and 25, we get 200. It is very easy to multiply any number with a number that have zeroes. As a result we easily get the answer i.e. 2400.

Lortetta and her family are going on vacation. Their destination is 610 miles from their home. Loretta is going to share some of the driving with her dad. Her average speed while driving 55 mph and her dad's average speed while driving is 65 mph. The plan is for Loretta to drive for the first 4 hours of the trip and her dad to drive for the remainder of the trip. Determine th enumber of horus it will take her family to reach their desination.

Answers

Answer: 10 hours

Step-by-step explanation:

First and foremost, we should note that:

Speed = Distance / Time

Total destination = 610 miles

Loretta speed = 55 mph

Time to be used by Loretta = 4 hours

Loretta's distance = Speed × Time = 55 × 4 = 220 miles

The distance to be covered by her dad will then be:

= 610 - 220

= 390 miles

Her dad's average speed = 65 mph.

Time taken by her dad will be:

= 390 / 65

= 6 hours

The number of hours to be used by the family will then be:

Time taken by Loretta + Time taken by her dad

= 4 hours + 6 hours

= 10 hours

use the function y=3/2x+3 to complete the table of values

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Given the function

Putting all the values of y=9, 6, 0, and -3 to complete the table

FOR y=9

putting y=9

switch sides

subtract 3 from both sides

Hence,

when y=9, x=4

FOR y=6

putting y=6

switch sides

subtract 3 from both sides

Hence,

when y=6, x=2

FOR y=0

putting y=0

switch sides

subtract 3 from both sides

Hence,

when y=0, x=-2

FOR y=-3

putting y=-3

switch sides

subtract 3 from both sides

Hence,

when y=-3, x=-4

Hence, the table becomes:

x                     y

9                    4

6                    2

0                    -2

Option 4 (4, 2, 3)

Step-by-step explanation:

Coordinances for a three-dimensional coordinate system are (x, y, z).

The letter labeling each axis is always on the positive side.

Therefore, all of the coordinances must be positive.

If you look at the x,y plane you can identify that the point is two over on the y axis and four over on the x.  You can use this same strategy on the z axis to get the coordinances (4, 2, 3).

Step-by-step explanation:

This is a difference of squares.

√x^2 - √49  is the basic formula for factoring a difference of squares. The  idea is that the middle term has been cancelled out.

√x^2 = x

√49 = 7

(x - 7)(x + 7) is the way this factors.

(x - 7)(x + 7)

===========

(x + 7)

The (x +7) in the numerator cancels with the (x + 7) in the denominator.

The answer is (x - 7)

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

She might have wanted you to do it like this.

(x + 7) || x^2  + 0x    - 49  || x     -   7

                   -7x      - 49   ...... Subtract.

Answers

Answer:

Plz Brain -list the answer  It takes effort tnx dear

Step-by-step explanation:

From given condition

equation of line is given as,

x*cos(α)+y*sin(α)=p

& as tanα= 5/12 so from Pythagoras theorem

sinα=  5/13

​cosα=  12/13

⇒12x+5y=39

⇒12x+5y−39=0

p = 3, α = tan-1 (5/12) So, tan α = 5/12 sin α = 5/13 cos α = 12/13 The equation of the line in normal form is given by By using the formula, x cos α + y sin α = p Now, substitute the values, we get 12x/13 + 5y/13 = 3 12x + 5y = 39 ∴
