x is your starting running time. 1/10 of a minute is 6 seconds, so you can do x - 6(6). 6 times 6 = 36, so your answer is x - 36 seconds. 36 seconds.

Answer:

Total change = <em>x </em>- 36 seconds.

Step-by-step explanation:

Let Greg's initial running time be <em>x </em>seconds.

Also, 1/10 minute = 6 seconds.

In the first week, his running time = <em>x </em>- 6

In the second week, his running time = <em>x </em>- 6 - 6 = <em>x </em>- 2(6)

In the third week, his running time = <em>x </em>- 6 - 6 - 6 = <em>x </em>- 3(6)

....

....

In the sixth week, his running time = <em>x </em>- 6(6) = <em>x </em>- 36

Hence, the total change = <em>x </em>- 36.

A new bean company is working on designing its label for the can. If the can measures 4 inches in height and has a 3 inch diamet
Arlecino [84]

Answer: 37.68 square inches of paper

Step-by-step explanation:

Hi to answer this question we have to calculate the side area (since the label doesn't cover the top and bottom area)

First, we have to find the circumference.

Circumference (C) = 2 π r

Since:  

Diameter = 2 radius

3 = 2r

3/2 =r

r =1.5 inches

Back with the circumference formula

Replacing with the values given:

C = 2 (3.14) 1.5

C= 9.42

Side area = C x heigth = 9.42 x 4 = 37.68 square inches

Ostrovityanka [42]

On a long hike Lucy drank 6 pints of water, which is equal to 3 quarts.

<h3>What is quarts?</h3>

An English measurement of volume equal to one-quarter gallon is the quart. There are now three different types of quarts in use: the liquid quart, dry quart, and imperial quart of the British imperial system. One liter is roughly equivalent to each. It is divided into four cups or two pints (in the US). The precise dimensions of the quart have historically changed in line with shifting values of gallons over time and in relation to various commodities.

A measure of liquid capacity that is equal to two pints or a quarter of a gallon, or roughly 0.94 liter in the US and 1.13 liter in the UK.

Since, 1 quart = 2 pints

Therefore by unitary method we can say,

2pint= 1 quart

6pint= 3quarts

Diego's family spends $87 on 4 tickets to the fair and a $39 dinner.
svlad2 [7]

Answer: b. Lin buys a pack of 87 pencils. She gives 39 to her teacher and shared the remaining pencils between herself and 3 friends.

Step-by-step explanation:

Lin buys 87 pencils which is why the entire number line adds up to 87.

She gave 39 of these pencils to her teacher which s why there is a section of the number line that is unlike the rest and is 39 in number.

The rest of the number line is a set of 4 spaces which are equal.

Lin shared the remaining pencils between herself and 3 friends which means she shared the pencils with 4 people. These four equal quantities of pencils are the 4 spaces.
