Answer:

h = 5/2

Step-by-step explanation:

\frac{3}{4} *\frac{1}{2} *h=\frac{15}{16} \\\\\frac{3}{8} *h=\frac{15}{16}

divide both sides by 3/8

h=\frac{5}{2}

Jim has some money ($n) in his pocket and his mum gives him $20. How much poney does he have now?​
liq [111]

Answer:

$n + $20

Step-by-step explanation:

Jim already has $n, and his mom has given him $20. We know we are not taking $n and subtracting $20, since his mom is adding that on to what he already has, we know we are not dividing, not multiplying but adding.

Conclusion : To find how much money he has now you would use the expression $n + $20

Hope this helps, please mark brainliest if possible. Have a nice day.

Help!! Which of the following uses the reciprocal property to rewrite 12/x-3 = 20/x+3?
loris [4]

<em><u>The reciprocal property is:</u></em>

\frac{x - 3}{12} = \frac{x + 3}{20}

<em><u>Solution:</u></em>

Given that,

\frac{12}{x - 3} = \frac{20}{x + 3}

<em><u>The reciprocal property is given as:</u></em>

The reciprocal of a fraction is the numerator and denominator switched

\frac{a}{b} = \frac{c}{d}\\\\Then\\\\\frac{b}{a} = \frac{d}{c}

Therefore,

\frac{12}{x - 3} = \frac{20}{x + 3}

By reciprocal property,

Switch the numerator and denominator of right side fraction as well as left side fraction

The we get,

\frac{x - 3}{12} = \frac{x + 3}{20}

Thus option C is correct

The graph shows the distance y, in centimeters, a pendulum moves to the right (positive displacement) and to the left (negative
AVprozaik [17]

Time required for the pendulum to swing from its position furthest to the right to its position furthest to the left: 1.25 seconds

Step-by-step explanation:

A pendulum is a system consisting of a rod/string connected to a mass which is left free to oscillate back and forth around its equilibrium position, straight vertical.

The period of a pendulum is the time the pendulum takes to complete one full oscillation, that means it is the time the pendulum takes to go from its furthest position on the left to the same position again. It is calculated as

T=2\pi \sqrt{\frac{L}{g}}

where L is the length of the pendulum and g the acceleration of gravity.

The figure in this problem represents the position of the pendulum. We observe that the time it takes for the pendulum to do one complete oscillation is 2.5 seconds.

The time it takes for the pendulum to swing from its position furthest to the right to its position furthest to the left is half the period: therefore, it is

\frac{T}{2}=\frac{2.5}{2}=1.25 s

Happy New Year!!
Kazeer [188]

145÷7.25 = 20

Step-by-step explanation:

This is a simple division of numbers with decimals.

Here we have dividend ( the number to be divided) (or numerator) = 145

and divisor (the number which divides dividend) (or denominator)= 7.25

Now, in case of decimals in denominator, we add number of zeroes in numerator equal to number of digits after decimal point in denominator, and thus the decimal point gets removed. So, this gives us 14500÷725, which by simple calculation is equal to 20.
