Monica deposits ​$200 into a savings account that pays a simple interest rate of 3.9​%. Paul deposits ​$300 into a savings account that pays a simple interest rate of 3.2​%. Monica says that she will earn more interest in 1 year because her interest rate is higher. Is she​ correct? Justify your response.

Answers

Answer: No, Monica is incorrect.  Paul will get more interest in 1 year.

Step-by-step explanation:

Formula: Simple interest : [tex]\dfrac{\text{principal x rate x time}}{100}[/tex]

Given: For Monica, Principal =$200, rate = 3.9%

Interest in 1 year = [tex]\dfrac{200\times3.9\times1}{100}=\$7.8[/tex]

For Paul, Principal =$300, rate = 3.2%

Interest in 1 year = [tex]\dfrac{300\times3.2\times1}{100}=\$9.6 > \$7.8[/tex]

Thus , Paul will get more interest in 1 year.

i.e. Monica is incorrect.

LIFE

I wonder what it's all about, and why
We suffer so, when little things go wrong?
We make our life a struggle,
When life should be a song.

Our troubles break and drench us,
Like spray on the cleaving prow
Of some trim Gloucester schooner.
As it dips in a graceful bow.

Our troubles break and drench us
But like that cleaving prow,
The wind will fan and drys us.
And we'll watch come other bow.

But why does sorrow drench us
When our fellow passes on?
We just exchanged life's dreary dirge
For an eternal life of song.

What is the inborn human trait
That frowns on a life of song?
That makes us weep at the journey's end,
When the journey was oft-times wrong?

Weep when we reach the door
That opens to let us in,
And brings to us eternal peace.
As it closes again in sin.

Millions have gone before us,
And millions will come behind.
So why do we fight
At a fate both wise and kind.

We hang into a jaded life
A life full of sorrow and pain.
A life that warps and breaks us,
And we try to run through it again and again.​

1. The number of triangles to the total number of shapes​

Answers

Answer:

count the number of triangles and then the total number of shapes so if there are 7 triangles and 21 shapes total the answer would be 7-21

Step-by-step explanation:

The ratio of the triangles to the total number of shapes will be 4/9. Then the correct option is D.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The total number of shapes is 9. And the number of triangles is 4.

Then the ratio of the triangles to the total number of shapes will be given as,

Ratio = 4 / 9

The ratio of the triangles to the total number of shapes will be 4/9. Then the correct option is D.
