Answer:

Yearly interest rate would be 6.3%

Step-by-step explanation:

Since, the amount formula of an investment after t years is,

A=P(1+\frac{r}{n})^{nt}

Where,

Expression (1+\frac{r}{n})^{nt} represents change factor in the investment,

In which, r = annul rate or yearly interest rate,

n = number of compounding periods,

t = number of years,

If change factor is (1.021)^{3t} or (1+0.021)^{3t}

Then,

By comparing,

\frac{r}{n}=0.021, n = 3

\implies r = 3\times 0.021= 0.063 = 6.3\%

Hence, yearly interest rate would be 6.3%

BigorU [14]

Answer:

Length of scale = 15 cm

Width of scale = 5 cm

Step-by-step explanation:

Dimensions of the kitchen of Mai are given as:

Length of kitchen = 6 m

Width of kitchen = 2 m

Scale to be used = 1 to 40

To find:

The drawing with labeling and dimensions of the scale drawing.

Solution:

First of all, let us understand about the concept of scaling.

Scaling is a method to represent big structures on paper.

For this purpose, we decide a scaling factor and draw the big structures on paper by scaling down (making it small) by using a scaling factor.

Here, the scale factor used is 1 to 40.

i.e. 1 unit on scale is equivalent to 40 units on the actual kitchen.

40 units of kitchen = 1 unit of scale

1 unit of kitchen = \frac{1}{40} units of scale

6 m of kitchen = \frac{1}{40}\times 6\ m = \frac{600}{40}\ cm = 15\ cm

Length of scale = <em>15 cm</em>

40 units of kitchen = 1 unit of scale

1 unit of kitchen = \frac{1}{40} units of scale

2 m of kitchen = \frac{1}{40}\times 2\ m = \frac{200}{40}\ cm = 5\ cm

Width of scale = <em>5 cm</em>

<em></em>

Please refer to the attached image as well for representation of given scale.

3/5 of gallon of juice is poured equally into 6 glasses . How much juice is in each glass?
Setler [38]
Hi there! For this question, we will have to divide. When it comes to dividing fractions, we keep, change, flip. In other words, keep the first fraction the same, change division into multiplication, and flip the second fraction over by its reciprocal. In this case, 3/5 stays the same and 6/1 becomes 1/6. 3/5 * 1/6 is 3/10 or 1/10 in simplest form. There. There are 1/10 gallon of juice in each glass.
