One gallon is equal to about 3.785 liters. What is this amount rounded to the nearest tenth? To the nearest hundredth? Show your work. ook at problem 3. What is the greatest number of whole liters of water you could pour into a one-gallon container without it overflowing? Explain your answer.

Answers

Answer:

3.8 ; 3.79 ; 3

Step-by-step explanation:

Given that:

1 gallon is equal to about 3.785 litres

3.785 to the nearest tenth :

Tenth digit = 7 ; round up 8 to 1 and add to 7

Hence,

3.785 = 3.8 (nearest tenth)

3.785 to the nearest hundredth :

Hundredth digit = 8 ; round up next digit 5 to 1 and add to 8

3.785 = 3.79 ( nearest hundredth)

What is the greatest number of whole liters of water you could pour into a one-gallon container without it overflowing?

The greatest Number of whole liters of water that could be poured into a 1 gallon container without it overflowing is 3 liters because, rounding up 3.785 to the nearest integer of 4 means we will exceed the maximum litres by about 0.215 gallons and hence, cause the container to overflow.

10 bags of chips and 8 soda cans cost $15.
5 bags of chips and 5 soda cans cost $8.
How much does a bag of chips cost? How much does a can of soda cost?

Answers

Answer:

One bag of chips costs $1.10

One can of soda costs $0.50

Step-by-step explanation:

1. Create a system of equations (b = bags of chips | s = soda)

10b + 8b = 15

5b + 5s = 8

2. Use the Elimination method by multiplying 5b+5s=8 by -2

10b + 8b = 15

-2(5b + 5s = 8)

=

10b + 8b = 15

- 10b - 10s = -16

(10b and -10b will cancel out, so you will only have s left)

=

-2s = -1

Divide by 2

Soda = 1/2, or $0.50

3. Plug in S (0.50) into an equation above and get B by itself

5b + 5(0.50) = 8

=

5b + 2.5 = 8

     - 2.5    -2.5

5b = 5.5

Bag of Chips = $1.10

The flu is starting to hit Weston. Currently, there are 380 people infected, and that number is growing at a rate of 15% per day. Overall, how many people will have gotten the flu in 7 days? If necessary, round your answer to the nearest whole number.

Answers

Answer:

1011 or 1010, depending on how you round. (I got 1011)

Explanation:

we need to calculate 15% of the non-constant x seven times.

x starts as 380.

15%=0.15

15% of x seven times:

380*0.15=57,

380+57=437;

437*0.15= 65.55,

437+65.55= 502.55;

502.55*0.15=75.38,

502.55+75.38=577.93;

577.93*0.15=86.69,

577.93+86.69=664.62;

664.62*0.15=99.69,

664.62+99.69=764.31;

764.31*0.15=114.65,

764.31+114.65=878.96;

878.96*0.15=131.84

878.96+131.84= 1011

What is the approximate length, in centimeters, of the diagonal from point A to point B in the right rectangular prism shown? Round your answer to the nearest whole centimeter.

A.8
B.9
C.10
D.11

Answers

Answer:

11

Step-by-step explanation:

First, find the diagonal along the base of the prism. Let B be the diagonal along the base.

8^(2)+6^(2)=b^(2)

64+36=b^(2)

100=b^(2)

10=b

Then let d be the diagonal from point A to point B

b^(2)+5^(2)=d^(2)

10^(2)+5^(2)=d^(2)

100+25=d^(2)

125=d^(2)

\sqrt(125)=d

11=d

Mr. Hamilton decorates his U.S. History classroom by putting up pictures of the presidents. The wall is 9.75 feet long. In the center, there is a window that is 5 3/4 feet long. ​ Each president's picture is 6 inches wide. If the pictures are placed side by side on either side of the window, how many pictures can he fit on this wall?

Answers

Answer:

8 pictures

Step-by-step explanation:

Given

[tex]Window = 5\frac{3}{4}ft[/tex]

[tex]Wall = 9.75ft[/tex]

[tex]Pictures = 6\ inches[/tex]

Required

Determine the number of pictures

First, we need to calculate the length of the available space

This is calculated by subtracting the width of the window from the width of the wall.

[tex]Space = Wall - Window[/tex]

[tex]Space = 9.75 - 5\frac{3}{4}[/tex]

Convert fraction to decimal

[tex]Space = 9.75 - 5.75[/tex]

[tex]Space = 4ft[/tex]

Since, the pictures are placed side by side.

This means that, there's no empty space between them.

Number of pictures is:

[tex]Number = \frac{Space}{Pictures}[/tex]

[tex]Number = \frac{4\ ft}{6\ in}[/tex]

Convert feet to inches

[tex]Number = \frac{4 * 12\ in}{6\ in}[/tex]

[tex]Number = \frac{48\ in}{6\ in}[/tex]

[tex]Number = \frac{48}{6}[/tex]

[tex]Number = 8[/tex]

Hence, 8 pictures can fit the wall

8 pictures
