Answer:

yes, Tony’s statement correct

Step-by-step explanation:

Lets solve both Left hand side and right hand side separately and then equate.

LHS

7\frac{1}{4} -3\frac{3}{4} = \frac{29}{4} -\frac{15}{4}

= \frac{29}{4} -\frac{15}{4 } = \frac{14}{4}

Taking RHS

4\frac{1}{4} -\frac{3}{4} = \frac{17}{4} -\frac{3}{4} =\frac{14}{4}

clearly LHS = RHS hence both quantities are equal to each other

How many liters of water must Sharon add to 2 liters of a sugar and water solution that is 36% sugar to create a solution that i
Dahasolnce [82]

The amount of sugar x in the starting solution contributes to a 36% concentration, so we have

\dfrac x2=0.36\implies x=0.64

units of sugar in the solution.

Into this solution, Sharon wants to pour y liters of water to obtain a smaller concentration of sugar in the overall solution:

\dfrac{0.64}{2+y}=0.12\implies\dfrac{16}3=2+y\implies y=\dfrac{10}3\approx3.33

So Sharon needs to add \dfrac{10}3 liters of water to the solution to get the desired concentration.

Nicolet wants to buy a new state of the art computer for R35 000. She decides to save by depositing an amount of R500 once a mon
sineoko [7]

Answer:

54.72 months

Step-by-step explanation:

Given:

Future value = R35,000

Annuity = R500

Interest = 11.32% per year

Interest per month, r = \frac{11.32}{12} = 0.943% = 0.00943

Let 'n' be the total time in months taken

Now,

Future value of annuity is calculated using the formula as:

\textup{Future value}=\textup{Annuity}\times[\frac{(1+r)^n-1}{r}]

on substituting the respective values, we get

35000=500\times[\frac{(1+0.00943)^n-1}{0.00943}]

or

70=[\frac{(1.00943)^n-1}{0.00943}]

or

1.6601 = 1.00943ⁿ

taking log both sides, we get

log(1.6601) = n × log(1.00943)

or

0.22= n × 0.00402

or

n = 54.72  months

In estimating the body temperature of a person, what difficulties did you encounter?Explain​
monitta

Answer:

In general , While estimating a bodies temperature that temperature is not the same for long, the temperature of the body is not at homeostasis, the temperature constantly has bumps and drops in the temperature this causes in accuracy thats why the thermometer takes 10-20 seconds because it takes the average of all the temperature's so it is accurate, that is a difficulty when estimating temperature because estimates are not good and the temperature keeps having ups and downs.
