Solve the following:<br>a) -5/4 [8/7+16/5]

Otrada [13]

Answer:

-38/7

Step-by-step explanation:

We are given $-\frac{5}{4}(\frac{8}{7}+\frac{16}{5})\\$ . First find the sum of the fractions in the parentheses. The greatest common multiple is 35 so we have $\frac{8}{7}+\frac{16}{5}=\frac{40}{35}+\frac{112}{35}$ .

The sum of $\frac{40}{35}+\frac{112}{35}$ is $\frac{152}{35}$ .

Now we multiply it by $-\frac{5}{4}$ so we have

$\\-\frac{5}{4} \cdot \frac{112}{35}\\=-\frac{1}{7}\cdot \frac{38}{1}\\=\boxed{-\frac{38}{7}}\\$

Flor tiene una papelería y vende los lápices en $12 y los bolígrafos en $20. ¿Qué expresión algebraica permite saber cuánto debe

stiks02 [169]

Answer:

c=120x+200y

Step-by-step explanation:

La expresión algebraica debería indicar que el valor total que debe cobrar Flor es igual a 10 que representa el número de bolsas por el resultado de la suma del precio de cada item por la cantidad, lo que se puede expresar de la siguiente forma:

c=10(12x+20y)

c=120x+200y

De acuerdo a esto, la expresión algebraica que permite saber cuánto debe cobrar Flor por 10 bolsas que contengan x cantidad de lápices y "y" cantidad de bolígrafos es c=120x+200y.

Brenda invests $4,848 in a savings account with a fixed annual interest rate of 5% compounded 2 times per year. What will the ac

s2008m [1.1K]

She invests some amount in a saving account of fixed interest compounded half-yearly. It says to find its Future Value after six years.

The principal amount is P = $4,848.

Annual interest rate is 5% i.e. r = 0.05

Compounding period is two times per year i.e. n = 2.

Time of investment is t = 6 years.

We know the formula of Future Value is given by :-

$FV=P*(1+\frac{r}{n})^{nt}$

We can plug the given values in the formula to calculate the answer.

$FV = 4848*(1+\frac{0.05}{2})^{(2*6)} \\\\ FV = 4848*(1+0.025)^{(12)} \\\\ FV = 4848*(1.025)^{(12)} \\\\ FV = 4848*(1.344888) \\\\ FV = 6520.02102$

Hence, future value of investment after six years is 6,520.02 dollars.
