Create a proportion using the form = to represent the following word problem.

Anna11 [10]

Answer :
x = 53.85

Step by step explanation:
If 78% of x (some numbers) is equal to 42, then we must set this as an equation to find it.

1) Rewriting 78% as a fraction and considering that when we say 78% of some number (x) we mean a product.
78% = 78/100 ➡️ 78/100x = 42

2) Then we can go on :
100 * 78/100x = 42 * 100
78x = 4200
78x/78 = 4200/78 ➡️ x = 53.85

3) Alternatively, simply dividing 42 by 0.78 (78%) would come to the same result :

42/0.78 = 53.85

Given an exponential function for compounding interest, A(x) = P(.95)x, what is the rate of change?

statuscvo [17]

Answer:

Option 3

The rate of change is -5%

Step-by-step explanation:

Given : An exponential function for compounding interest, $A(x) = P(.95)^x$

To find : What is the rate of change?

Solution :

The general form of an exponential function is:

$f(x) = a(1+r)^x$

Where, a is the initial amount,

(1+r) is the rate of change,

r is the growth or decay factor

We have given, $A(x) = P(.95)^x$

Rate of change is

$1+r=0.95$

$r=0.95-1$

$r=-0.05$

Convert to percent,

$r=-0.05\times 100=-5\%$

Therefore, Option 3 is correct.

Jenna saves $3 for every $13 dollars she earns. Vanessa saves $6 for every $16 she earns. Is Jenna's ratio of money saved to mon

jeka94

We have been given that Jenna saves $3 for every $13 dollars she earns. Vanessa saves $6 for every $16 she earns.

We can compare the ratios of saved money to earned money by Jenna and Vanessa as:

$\frac{3}{13} =\frac{6}{16}$

Let us simplify our equation.

$0.2307692307692308=0.375$

We can see that $0.231\neq 0.375$ , therefore, Jenna's ratio of money saved to money earned is not equivalent to Vanessa's ratio of money saved to money earned.
