Answers

Answer 1

Answer:

205 sec

2x = 410

x = 205

what is the slope? thank you for anyone who helps ​

Answers

Answer:

1/4

Step-by-step explanation:

We can find the slope by using the slope formula

m = ( y2-y1)/(x2-x1)

   = ( 4 -3)/( 6-2)

   = 1/4

GIVEN :-

Coordinates of first point on the line are (2,3)

Coordinates of second point on the line are (6,4)

TO FIND :–

Slope of a line

Formula :-

⠀⠀⠀⠀[tex]\boxed{\sf{m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1}} }}[/tex]

where,

m = slope of a line

x2 and y2 = (6,4)

x1 and y1 = (2,3)

By substituting values according to the formula we get,

[tex]\sf{⟹m = \dfrac{4 - 3}{6 - 2} }[/tex]

[tex]\sf{⟹m = \dfrac{1}{4} }[/tex]

Hence, The line of a slope(m) is ¼

Use the simple interest formula.

You deposit $650 in a savings account. How long does it take an account with an annual interest rate of 5% to earn $178.25 in interest? Round your answer to the nearest tenth.

Answers

Answer:

The Answer is 5.5, rounded to the nearest tenth

Step-by-step explanation:

650 x .05 = 32.5

178.25 ÷ 32.5 = 5.48461538462

5.48461538462 rounds to 5.5

It will take 5 years and 6 months to earn $178.25 in interest.

What is the simple interest?

Simple interest is the borrowing amount added only to the principal amount.

The Formula to calculate the simple interest is;

                                                 S.I. = P x T x R / 100,

Where S.I. is simple interest, P is principal amount, T is time period and R is interest rate in a year.

Given:

You deposit $650 in a savings account with an annual interest rate of 5% to earn $178.25 in interest.

That means,

178.25 = 650 x 5 x t/100

t = 17825/3250

t = 5.5

Therefore, it will take 5 years and 6 months.
