Answers

Answer 1

Given Length of Cuboid = 12cm

Given Breadth of Cuboid = 9cm

Given height of Cuboid = 8cm

Total Surface area of cuboid = 2(lb + bh + hl)

where, l stands for legth of the cuboid, b stands for breadth of the cuboid and h stands for height of the cuboid.

Put the given values of l,b and h in the formula

=> Total surface area of cuboid = 2((12×9)+(9×8)+(8×12))

=> 2(108 + 72 + 96)

=> 2(180 + 96)

=> 2 × 276

=> 552 sq. cm is the total surface area of cuboid

9. At the bowling alley, Angela rented shoes for $3 and it cost her $2.50 to bowl each game.
a) State an equation that represents the cost of bowling in the form C = mx + b, where C is the total
cost and x is the number of games bowled.
b) How much did it cost her to bowl four games?​

Answers

Answer:

$13

Step-by-step explanation:

For the equation, m will be 2.50 and b will be 3.  This is because 2.50 will change as she plays more games.  The 3 will stay the same no matter how many games she plays.

C = 2.5x + 3

To find the cost to bowl four games, plug 4 into x and solve for C.

C = 2.5x + 3

C = 2.5(4) + 3

C = 10 + 3

C = 13

What is her average speed in miles/min?

- Show how you convert the average speed to mis. Show your set up and answer.

Answers

Answer:

V_avg = 0.5556 miles/min

V_avg = 0.00926 miles/sec

Step-by-step explanation:

Bonita jogs 2.5 miles west of Vinces' house to school. It took her 15 minutes to arrive.

Speed 1; distance/time = V1 = 2.5/15 = 1/6 miles/min

Furthermore she ran 5 miles to the discount store for personal supplies. This took her 5 minutes.

Thus;

Speed 2; V2 = 5/5 = 1 mile/min

She then slowly walks back to school, which takes her another 10 minutes. Distance from the discount stor to school is 5 miles as stated in speed 2.

Thus;

Speed 3: V3 = 5/10 = ½ mile/min

Her average speed is;

V_avg = (V1 + V2 + V3)/3

V_avg = (1/6 + 1 + ½)/3

V_avg = 10/18 = 0.5556 miles/min

Converting to miles/seconds

60 seconds make 1 minutes, therefore 1 mile/min = 1/60 miles/seconds

Thus;

V_avg = 0.5556 miles/min = 0.5556 × 1/60 miles/sec = 0.00926 miles/sec

Which property is shown in the matrix addition below?
[-6 15 -2 ] + [6 -15 2 ] = [0 0 0

Answers

Answer:

The property shown in matrix addition given is "Additive Inverse Property"

Step-by-step explanation:

First of all lets define what a matrix is.

A matrix is an array of rows and columns that consists of numbers. There are several types of matrices. The one in our question is a row matrix which consists of only one row.

There are several addition properties for matrices.

One of them is additive inverse property. The additive inverse of a matrix consists of the same elements but their signs are changed.

Additive inverse property states that the sum of a matrix and its additive inverse is a zero matrix.
