2) The equation shows how changes in matter are related to changes in energy.

3) the amount of energy released in nuclear reactions is so much larger than the energy released in chemical reactions

4) False

5) True

6) True

7) E = mc²
E = (0.0304)(3*10^8)²
E = 2.736 * 10^15 J

8) E = Mc²
E = 3 kg * (3 * 10⁸ m/s²
E = 3 kg * 9 * 10¹⁶ m/s²
E = 27 * 10¹⁶ kg-m/s²
E = 2.7 * 10¹⁷ kg-m/s²

9) 3 * 10²⁰ = m * 3 * 10⁸
m = 3 * 10²⁰ / 3 * 10⁸
m = 10¹² Kg

10) E = (3 * 10⁻²⁸)(3 * 10⁸)²
E = 3 * 10⁻²⁸ * 9 * 10¹⁶
E = 27 * 10⁻¹²
E = 2.7 * 10⁻¹¹ J

Hope this helps!

Step-by-step answer

P Answered by PhD

4

Part 1) 9 and 1 over 2 divided by 1 over 4

Part 2) 18, because the number of catalogs is 72 over 5 divided by 4 over 5

Part 3) 3.2

Part 4) 3.6 with bar over 6

Part 5) 4 over 7 and 4 over 9

Part 6) 43 over 9

Part 7) Benny spent to go to the summer camp $280.00

Part 8) $124

Part 9) (−$11) ⋅ 12

Part 10) -27 ft

Step-by-step explanation:

Part 1)

Let

x ------> the number of days

we now that

The total distance jogged must be equal to the distance jogged each day multiplied by the number of days

$9\frac{1}{2}=\frac{1}{4}x$

Solve for x

$x=\frac{9\frac{1}{2}}{\frac{1}{4}}$

therefore

The number of days is

9 and 1 over 2 divided by 1 over 4

Part 2)

Let

x ----> the number of catalogs

we know that

To find out the number of catalogs, divide the wide of the shelf by the thick of each catalog

$x=\frac{\frac{72}{5}}{\frac{4}{5}} =\frac{72}{4}= 18\ catalogs$

therefore

18, because the number of catalogs is 72 over 5 divided by 4 over 5

Part 3) Convert 16 over 5 to a decimal

we know that

$\frac{16}{5}=16(\frac{1}{5})=16(0.2) =3.2$

Part 4) How can 33 over 9 be expressed as a decimal?

we know that

$\frac{33}{9}= 3.666666...$ ----> is a repeating decimal

therefore

3.6 with bar over 6

Part 5) Which of the following numbers can be expressed as repeating decimals?

Verify each case

case a) 4 over 7

$\frac{4}{7}= 0.571428571428571428...$ ----> is a repeating decimal

case b) 2 over 5

$\frac{2}{5}=0.40$ ----> is a terminating decimal

case c) 7 over 8

$\frac{7}{8}=0.875$ ----> is a terminating decimal

case d) 4 over 9

$\frac{4}{9}=0.44444...$ ----> is a repeating decimal

therefore

4 over 7 and 4 over 9

Part 6) Which of the following rational numbers is equal to 4 point 7 with bar over 7 ?

Verify each case

case a) 43 over 9

$\frac{43}{9}= 4.77777...$

case b) 49 over 9

$\frac{49}{9}= 5.444444...$

case c) 35 over 9

$\frac{35}{9}= 3.888888...$

case d) 32 over 9

$\frac{32}{9}= 3.55555...$

therefore

43 over 9

Part 7)

we know that

1)Benny deposited $92.50 into his account every month for 10 month

so

$\$92.50(10)=\$925.00$

2) He used $36.50 every month to pay for art lessons

$\$925.00-10(\$36.50)=\$560.00$ -----> total money left in his account after 10 months

3) After 10 months, he used 1 over 2 of the total money left in his account to go to a summer camp for artists

so

$(1/2)(\$560)=\$280.00$

therefore

Benny spent to go to the summer camp $280.00

Part 8)

we know that

1) Mini earned $160 during the summer doing chores

2) She bought 3 dresses worth $12 each using her chore money.

so

$3(\$12)=\$36$

To find out how much money was left, subtract $36 from the amount earned during the summer doing chores

$\$160-\$36=\$124$

therefore

$124

Part 9)

we have

1 year=12 months

Let

x ----> the total deductions for the year

we know that

The total deductions for the year is equal to the Ryan's tennis club membership multiplied by the number of a months in a year

so

$x=(-\$11)12=-\$132$

therefore

(−$11) ⋅ 12

Part 10)

we know that

The total depth of a submarine is 45 ft

$15\%=15/100=0.15$

15% of 45 ft is

(0.15)(45)=6.75 ft

using proportion

Find out the deep after 4 minutes

Let

x ----> the deep after 4 minutes

$\frac{6.75}{1}\frac{ft}{min}=\frac{x}{4}\frac{ft}{min}\\\\x=6.75(4)\\\\x=27\ ft$

therefore

-27 ft

we now that

The total distance jogged must be equal to the distance jogged each day multiplied by the number of days

$9\frac{1}{2}=\frac{1}{4}x$

Solve for x

$x=\frac{9\frac{1}{2}}{\frac{1}{4}}$

therefore

The number of days is

9 and 1 over 2 divided by 1 over 4

Part 2)

we know that

To find out the number of catalogs, divide the wide of the shelf by the thick of each catalog

$x=\frac{\frac{72}{5}}{\frac{4}{5}} =\frac{72}{4}= 18\ catalogs$

therefore

18, because the number of catalogs is 72 over 5 divided by 4 over 5

Part 3) Convert 16 over 5 to a decimal

we know that

$\frac{16}{5}=16(\frac{1}{5})=16(0.2) =3.2$

Part 4) How can 33 over 9 be expressed as a decimal?

we know that

$\frac{33}{9}= 3.666666...$ ----> is a repeating decimal

therefore

3.6 with bar over 6

Part 5) Which of the following numbers can be expressed as repeating decimals?

Verify each case

case a) 4 over 7

$\frac{4}{7}= 0.571428571428571428...$ ----> is a repeating decimal

case b) 2 over 5

$\frac{2}{5}=0.40$ ----> is a terminating decimal

case c) 7 over 8

$\frac{7}{8}=0.875$ ----> is a terminating decimal

case d) 4 over 9

$\frac{4}{9}=0.44444...$ ----> is a repeating decimal

therefore

4 over 7 and 4 over 9

Part 6) Which of the following rational numbers is equal to 4 point 7 with bar over 7 ?

Verify each case

case a) 43 over 9

$\frac{43}{9}= 4.77777...$

case b) 49 over 9

$\frac{49}{9}= 5.444444...$

case c) 35 over 9

$\frac{35}{9}= 3.888888...$

case d) 32 over 9

$\frac{32}{9}= 3.55555...$

therefore

43 over 9

Part 7)

we know that

1)Benny deposited $92.50 into his account every month for 10 month

so

$\$92.50(10)=\$925.00$

2) He used $36.50 every month to pay for art lessons

$\$925.00-10(\$36.50)=\$560.00$ -----> total money left in his account after 10 months

3) After 10 months, he used 1 over 2 of the total money left in his account to go to a summer camp for artists

so

$(1/2)(\$560)=\$280.00$

therefore

Benny spent to go to the summer camp $280.00

Part 8)

we know that

1) Mini earned $160 during the summer doing chores

2) She bought 3 dresses worth $12 each using her chore money.

so

$3(\$12)=\$36$

To find out how much money was left, subtract $36 from the amount earned during the summer doing chores

$\$160-\$36=\$124$

therefore

$124

Part 9)

we have

1 year=12 months

Let

x ----> the total deductions for the year

we know that

The total deductions for the year is equal to the Ryan's tennis club membership multiplied by the number of a months in a year

so

$x=(-\$11)12=-\$132$

therefore

(−$11) ⋅ 12

Part 10)

we know that

The total depth of a submarine is 45 ft

$15\%=15/100=0.15$

15% of 45 ft is
