Wht is 84 is 74% of what number

1 answer:

'is' in mathematics means equal
'of' in mathematics means multiplication

percent means over 100

84 = 74% * x

84 = 74/100 * x

84 = 37/50 * x

Multiply 50/37 on both sides, so we can isolate 'x'

85 * 50/37 = x

x = 4250/37

x ≈ 114.864865

84 is 74 percent of <span>114.86</span>.

Change the subject of the equation v = u + at to a.

emmasim [6.3K]

<h3>Answer ↓</h3>

<h3>Calculations ↓</h3>

In order to make a the subject of this equation , we need to get a by itself .

The current equation is :

v = u + at

Subtract u on both sides :

v-u=at

Now, divide by t on both sides :

v-u/t=a

<h3>So the formula looks like ↓</h3>

$\boxed{\\\begin{minipage}{3cm}Equation \\ a=$\displaystyle\frac{v-u}{t} $ \\ \end{minipage}}$

A vector has an x-component of −24.5 units and a y-component of 31.5 units. Find the magnitude and direction of the vector.

jasenka [17]

we are given a vector

whose

x-component is -24.5

so, $v_x=-24.5$

y-component is 31.5

so, $v_y=31.5$

Magnitude:

we can use formula

$|v|=\sqrt{(v_x)^2+(v_y)^2}$

we can plug values

$|v|=\sqrt{(-24.5)^2+(31.5)^2}$

$|v|=39.90614$

Direction:

we can use direction formula

$\theta=tan^{-1}(\frac{v_y}{v_x})$

now, we can plug values

$\theta=tan^{-1}(\frac{31.5}{-24.5})$

$\theta=180-52.12$

$\theta=127.88$ ................Answer
