Using a savings amount of $450, assume you deposited the total amount

Mathematics
1 answer:
ankoles [38]3 years ago

Answer:

<h2> 7.3%</h2>

Step-by-step explanation:

Using the formula for calculating the simple interest to get the rate of return;

Simple Interest = Principal * Rate * Time/100

Given Principal = $450,

Time (in years) = 1 year

Simple interest = $32.75

Rate (in %) =?

Substituting the given values in the given formula to get the rate;

32.75 = 450*1*R/100

450R = 3275

R = 3,275/450

R = 7.3%

The rate of return is  7.3%

babunello [35]

2) 200 mL

3) 0.2 kg

Step-by-step explanation:

2)

In this problem, we know that:

- With 1 liter of juice, we can fill a total of 5 cups

So we know that the total volume of 5 cups is equal to

V = 1 L

This means that the volume of each cup is equal to the total volume divided by the number of cups (5), therefore:

V_1=\frac{V}{5}=\frac{1L}{5}=0.2 L

And keeping in mind the equivalence between liters and milliliters:

1 L = 1000 mL

This means that the capacity of each cup is

V_1=0.2 L \cdot 1000 mL/L = 200 mL

3)

Here we want to find the mass contained in each cup.

We know that the mass of a substance is related to each volume by the equation

d=\frac{m}{V}

where

d is the density

m is the mass

V is the volume

In this problem, we have:

V = 0.2 L is the volume of juice in each cup

d=1kg/L is the density of juice (assuming it is the same as the density of water)

So, the mass of juice in one cup is:

m=dV=(1)(0.2)=0.2 kg

Natalka [10]

Answer:

y = -3/7x + 5

Step-by-step explanation:

y2 - y1 / x2 - x1

2 - 8 / 7 - (-7)

-6/14

= -3/7

y = -3/7x + b

2 = -3/7(7) + b

2 = -3 + b

5 = b

Start at 200. creat a that multiples each number by two stop when you have 5 numbers.
Leokris [45]

200

200*2 = 400

400*2 = 800

800*2 = 1600

1600*2= 3200

This is 5 numbers

If you want 5 numbers that are multiplies by 2

3200*2 =6400
