From a rectangular piece of cardboard having dimensions a × b, where a = 20 inches and b = 70 inches, an open box is to be made by cutting out an identical square of area x2 from each corner and turning up the sides (see the figure). Express the volume V of the box as a function of x.

Answers

check the picture below.

The volume of the box as a function of x will be 1400x - 180x² - 4x³.

First and foremost, you should note that the volume of a rectangular prism is given as:

= Length × Width × Height

where,

Length = 70 - 2x

Width = 20 - 2x

Height = x

Volume = Length × Width × Height

Volume = (x)(20 - 2x)(70 - 2x)

Volume = 1400x - 40x² - 140x² + 4x³

Volume = 1400x - 180x² - 4x³

Therefore, the volume of the box as a function of x will be 1400x - 180x² - 4x³.

To do this we have to multiply 20 with 0.0625

20×0.0625

1.25 pounds

20 oz is equal to 1. 25 lb

Hence, the nuts in pounds is 1. 25 lb if Joe bought 20 ounces of nuts at the store.

Use the empirical rule to calculate estimates of tolerance intervals containing 68.26 percent, 95.44 percent, and 99.73 percent of all possible bank customer waiting times. (round your answers to 3 decimal places. negative amounts should be indicated by a minus sign.)

Answers

By empirical rule, 68.36 percent lie within 1 standard deviation of mean on either side, similarly, 95.44 and 99.7 percent lie in 2 and 3 standard deviations respectively. So, 68.36% tolerance interval is (134.5-16.6343 to 134.5+16.6343) which is (117.8657 to 151.1343) 95.44% tolerance interval is (134.5-2*16.6343 to 134.5+2*16.6343) which is (101.2314 to 167.7686) 99.73% tolerance interval is (134.5-3*16.6343 to 134.5+3*16.6343) which is (84.5971 to 184.4029)

at a wedding dance couples have new partners nine times during a five minute song how long does one couple dance together

one couple dances toghether for _ of a minute

Answers

33.33333333333333333 seconds for every dance with couple

Final answer:

To determine how long one couple dances together, divide the total song duration by the number of times partners change plus one. With nine partner changes during a five-minute long song, each couple dances together for 0.5 minutes.

Explanation:

The question involves calculating the amount of time one couple dances together during a wedding dance if couples change partners nine times during a five-minute song. To find the answer, we need to divide the total time of the song by the number of times the partners change.

First, we find out how many times the couples will dance together. If they switch partners nine times, there will be ten different dancing intervals. Next, we divide the total length of the song by the number of intervals:

5 minutes ÷ 10 intervals = 0.5 minutes per interval.

Therefore, one couple dances together for 0.5 of a minute.

what number must you add to complete the square x^2+24x=17

Answers

We have
x² + 24x = 17 (1)

Note that
(x + 12)² = x² + 24x + 144
By adding 144 to the left side of equation (1), it becomes a perfect square.

Therefore
x² + 24x = (x+12)² - 144 (2)

Substitute (2) into (1).
(x + 12)² - 144 = 17
(x + 12)² = 17 +144
(x + 12)² = 161

Answer:
We added 144 to the left side of equation (1) in order to make it a perfect square.

Jenny charges for delivering the cakes.

Bob lives 12 miles away.

How much will Jenny charge to deliver the cakes? delivery charges £4 mixed cost + 60p per mile

Answers

Final answer:

To deliver the cakes to Bob, Jenny will charge £11.20.

Explanation:

To calculate the delivery charges, we need to find the distance between Jenny's location and Bob's location. Since Bob lives 12 miles away, the delivery distance will be 12 miles. Jenny charges £4 as a mixed cost plus 60p per mile. So, the delivery charge will be £4 + (12 miles * 60p) = £4 + £7.20 = £11.20.

What is Unitary method?

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Steps to Use Unitary Method

First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.

Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.

Given:

riding at a rate of 9 miles per hour
