Answer:

\large{ \tt{☄ \: EXPLANATION}} :

✎ Firstly , Remember these things :

  • To convert the percentage into a decimal fraction, remove the % symbol and divide it by 100 as in the case of conversion of percentage into fraction. We know that , divide by 100 means shifting to the left ; so to convert a percentage into decimal fraction, remove the % symbol and shift the decimal point two places to the left. For example : 12\% =  \frac{12}{100}  = \boxed{  0.12}

\large{  \tt{☥ \: LET'S \: SOLVE}} :

\large{1. \:  \: 52\%  \: \text{of} \: 210 =  \frac{52}{100} \times 210 = 0.52 \times 210 =  \boxed{109.2}  }

\large{ 2. \:  \: 35\%  \: \text{of} \: 500 =  \frac{35}{100}  \times 500 = 0.35 \times 500 =  \boxed{175} }

\large{3. \: 28\%  \: \text{of}  \: 866 =  \frac{28}{100} \times 866 = 0.28 \times 366 =  \boxed{102.48} }

\large{ \tt{✺ \: REPEAT \: DAILY} }:

Theoretical probability is what we expect to happen. For example, we do a test of flipping a coin. You know that its either gonna be heads or tails.

Experimental probability is what actually happens when we try it out. It occurs when we are doing an experiment and then something happens.

A rental truck cost $48 plus $0.40 per mile.
Natalija [7]
(a) If we let x be the number of miles and y be the total cost, the equation for relating the number of miles and the total cost would be,
                                y = 0.4x + 48

(b) If the rental cost is 60,
                               60 = 0.4x + 48
The value of x from the equation is 30.

(c) You may prepare the table of values by allowing x be any number and then solve for y until we arrive with an answer for y being equal to 60.

jenny borrowed $500 for 5 years at 4% interest compounded annually. what is the total amount she will have paid when she pays of
alexdok [17]
Use the formula for compound interest,  
  
A=P(1+ \frac{r}{n})^{nt}  
  
Where P is the starting amount (500$), r is the rate of interest (0.04), n is the number of times the interest is compounded per unit (1 per year), and t is the amount of time it is compounded (5 years).  
  
Now, plug it into the formula:  
  
A=500(1+ \frac{0.04}{1})^{5}  
  
Do the math, and your answer is she must pay <span>608.32$ when she pays her debts.</span>

A soccer ball is kicked from ground level. The function y = -12x (x - 6) shows the height in feet) of the
enot [183]

Answer:

6 seconds

Step-by-step explanation:

Given

y = - 12x(x - 6)

When the ball hits the ground then height of ball is zero

let y = 0 , that is

- 12x(x - 6) = 0

Equate each factor to zero and solve for x

- 12x = 0 ⇒ x = 0 ← when ball is first kicked

x - 6 = 0 ⇒ x = 6 ← when the ball hits the ground.

The ball hits the ground after 6 seconds
