Which of the following is the best estimate in meters for the average width of doorway?

Standard interior doors typically range from0.7 to 0.9 metersin width and 2.0 to 2.1 meters in height. Thus, average width of the door way is about 1.0 m.

Here are the calculations for the gumballs:

• Total Gumballs: 120
• Red Gumballs: 20% of 120 = 24
• Orange Gumballs: 30% of 120 = 36
• Yellow Gumballs: 5% of 120 = 6
• Green Gumballs: 10% of 120 = 12
• Blue Gumballs: 120−(24+36+6+12) =42

Difference

The difference between the number of blue gumballs and yellow gumballs is: 42 − 6=36

To find the area of the largest circle that fits in the rectangle, we need to determine the area of a circle with a diameter of 8 cm or less to fit on the rectangle with the given measurements as illustrated below.

​​​​​​​

Area of circle= πr2

Radius of circle, r=8cm/2=4cm

Then, area of the largest circle is:

Area of circle= π*4 cm *4 cm =16π cm2

To calculate the number of months it will take to pay off the television, we first subtract the down payment from the total cost of the television:

1,570−400=1,170

Now, we divide the remaining balance by the monthly payment amount:

1,170÷100=11.7

Since the consumer cannot make a fraction of a payment, it will take 12 months to pay off the television.

Let two number be x and y. Then

Three time a number=3x

Eight times a different number=8y

Sum of the two is 3x+8y

Given the equation D=2R means that the get the value of D, multiply the value of R by 2. That is D is two times the value of R.

C. 3.9 meters

Explanation

To convert centimeters to meters, we divide by 100

1 meter = 100 centimeters.

390 cm÷100

=3.9 meters

Change in weight of client=new -old=1072-841= 231

Percent change=change/old*100%=231/841*100%=27.47%

The percentage change increase is about 27%

To calculate the average rate of change per month, we first determine the total change in the account balance and then divide that by the number of months over which the change occurred.

The change in the balance from March 15 to August 15 is:

Changeinbalance=1450−1140=310

Now, we calculate the number of months between March 15 and August 15:

Numberofmonths=5months

Next, we find the average rate of change per month:

Averagerateofchangepermonth = = 62
