xxMikexx [17]

Answer:

1%

Step-by-step explanation:

\text{\color{blue}{100\%} represents the \color{blue}{starting balance}: \color{blue}{\$50}.}

100% represents the starting balance: $50.

Method 1

Express the ending balance as a percentage of the starting balance:

\frac{\color{darkviolet}{\$50.50}}{\color{blue}{\$50}}=

$50

$50.50

​

=

\,\,1.01

1.01

1.01\times100=

1.01×100=

\,\,\color{darkviolet}{101\%}

101%

\text{Subtract the starting \color{blue}{100\%} to get the \color{green}{percent interest}:}

Subtract the starting 100% to get the percent interest:

\color{darkviolet}{101\%}-\color{blue}{100\%}=

101%−100%=

\,\,\boxed{\color{green}{1\%}}

1%

Two gears in a machine are aligned by a mark drawn from the center of one gear to the center of the other. If the first gear has
Aleksandr [31]

Answer:

5

Step-by-step explanation:

for the first gear

revolutions/teeth

1 / 24

2 / 48

3 / 72

4 / 96

5 / 120

6 / 144

for the second gear

revolutions/teeth

1 / 40

2 / 80

3 / 120

4 / 160

<em>the two marks will meet after 120 teeth, 5 revolutions of the first gear and 3 revolutions of the second.</em>

the way to get that amount of teeth is

24 = 2 \times 2 \times 2 \times 3 =  {2}^{3}  \times 3

40 = 2 \times 2 \times 2 \times 5 =   {2}^{3}  \times 5

the Least Common Multiple equals the product of all factors, but those factors who are repeted for both numbers should be only once.

{2}^{3} \times 5 \times 3 = 120

120 teeth are 5 revolutions for gear1 and 3 por gear2

Please help !!!!!!!!!
Kaylis [27]

Answer:

9) JK = 24.5

10) LM = 24.5

11) m∡L = 51°

12) m∡M = 129°

Step-by-step explanation:

in a parallelogram, adjacent angles are supplementary (add to 180 degrees) and are also congruent

so, ∡K = ∡M and ∡J = ∡L

since ∡'s L and M are adjacent we can add them and set them equal to 180

5z - 6 + 2z - 3 = 180

7z - 9 = 180

7z = 189

z = 27

therefore, m∡M = 5(27)-6 = 129 and m∡L = 180-129, or 51

Also in a parallelogram, opposite sides are equal; so KJ = LM and KL = JM

7x = 3x + 14

subtract 3x from each side to get:

4x = 14

x = 14/4 = 3.5

to find measure of JK, substitute 3.5 for 'x' to get (3.5)(7) = 24.5

to find measure of LM, substitute 3.5 for 'x' to get (3.5)(3)+14 = 24.5
