Nicolas has $650 to deposit into two different savings accounts. • Nicolas will deposit $400 into Account I, which earns 3.5% an

Nitella [24]

The initial amount is $650. The $400 is deposited in Account 1 with 3.5% annual simple interest. The $250 is deposited in Account 2 with 3.5% interest compounded monthly.
n = 2 years
Account 1: Simple Interest

F = P (1+rn)
= 400 (1 +(0.035*2))
= $428

Account 2: Compound Interest

F = P (1+i)^n
= 250 ( 1+0.035)^2
F = 267.81

Total money after 2 years = $428 + $267.81
T = $695.81

Answer:

$-\dfrac{3}{5}$

Step-by-step explanation:

1. Find the numerator:

$\dfrac{1}{3}-\dfrac{5}{6}=\dfrac{1\cdot 2}{3\cdot 2}-\dfrac{5}{6}=\dfrac{2}{6}-\dfrac{5}{6}=\dfrac{2-5}{6}=-\dfrac{3}{6}=-\dfrac{1}{2}.$

2. Simplify the fraction:

$\dfrac{-\frac{1}{2}}{\frac{5}{6}}=-\dfrac{1}{2}\cdot \dfrac{6}{5}=-\dfrac{3}{5}.$

The sum of two numbers is no more than 28. Let x represent the first number, and let y represent the second number. Which

Ostrovityanka [42]

$x + y\leq 28$ is the inequality that represents this situation

Solution:

Given that sum of two numbers is no more than 28

Let "x" represent the first number

Let "y" represent the second number

To find: Inequality that represents this situation

Sum of two numbers means we have to add "x" and "y"

Sum of two numbers is no more than 28

Here, "no more than 28" , means that not greater than 28

It can be less than or equal to 28

Thus we frame a inequality as,

$\text{ sum of x and y } \leq 28$

$x + y\leq 28$

Thus the required inequality is found

Ella is stuffing envelopes. She has 48 red pages, 25 white pages, and 84 blue pages. If she need to put 2 red pages, 1 white pag

Marina CMI [18]

Divide each number of pages she has, with the number of pages required.

48 red pages divided by 2 red pages.

48 ÷ 2 = 24

25 white pages divided by 1 white pages.

25 ÷ 1 = 25

84 blue pages divided by 4 blue pages.

84 ÷ 4 = 21

Now add the total amount.

24 + 25 + 21 = 70

Ella can make 70 envelopes.
