115.5  is the total amount of interest paid by this investment at the end of 5 years

percentage, a relative value indicating hundredth parts of any quantity.

Given,

Samantha invested $660 into an account that paid 3.5% interest compounded annually.

We need to find  total amount of interest paid by this investment at the end of 5 years

A=P(1+rt)

A is final amount

P is principal amount

r is rate of interest

t is time

A=?,P=660,r=3.5%=0.035, t=5

A=660(1+0.035(5))

=660(1+0.175)

=660(1.175)

A=775.5

To check the total amount of interest paid by this investment at the end of 5 years

We need to find difference between initial amount and final amount

775.5-660

115.5

Hence 115.5  is the total amount of interest paid by this investment at the end of 5 years

Answer:

-5

Step-by-step explanation:

Answer:

The two cities are 1,000 miles apart

Step-by-step explanation:

The key to solving this is in the scale given:

4cm represents 25 miles

4cm = 25 miles

∴ 1 cm = 25 ÷ 4 = 6.25 miles

Measured distance on map = 160cm

1 cm = 6.25 miles

∴ 160 cm = 160 × 6.25 = 1000 miles

∴ The two cities are 1,000 miles apart

Answer:

10 pencils

Step-by-step explanation:

Given that:

Number of pencils bought by Sam and Sara are the same.

Let the number of pencils bought = x

Sam put 1/4 in his pencil box

Sara put 1/2 in her pencil box

1/4 of Sam's pencil = 5

That is ;

1/4 of x = 5

x /4 = 5

x = 20

Hence, number of pencils Sara put in her box

:

1/2 of 20

1/2 * 20

20/2

= 10

10 pencils

Step-by-step explanation:

because nine divided by 3 is 3 then subtract 3 which is 0 then subtract 3 again which is -3

The equation to determine how each of them contributed is

x= 30/5 = $6.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

We have,

They have $30.00 to spend between them.

let $x be the amount each contributed.

So, the equation to determine how each of them contributed

x = 30/ 5

x= $6.

Step-by-step explanation:

Considering the line graph

Some of the points on the line are given by

Finding the slop between any two given points

Let us take the point (0, 5) and (2, 6)

[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:5\right),\:\left(x_2,\:y_2\right)=\left(2,\:6\right)[/tex]

[tex]m=\frac{6-5}{2-0}[/tex]

To the  y-intercept, set x = 0.

We already know that when x = 0, the value of y = 5

so

Equation of line can be obtained using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = 1/2 and any point let say (2, 6)

[tex]y-6=\frac{1}{2}\left(x-2\right)[/tex]

add 6 to both sides

[tex]y-6+6=\frac{1}{2}\left(x-2\right)+6[/tex]

[tex]y=\frac{1}{2}x+5[/tex]

Linear bc the equation of this scenario is y=4x+20  

Step-by-step explanation:

Answer:

(6, 1)

Step-by-step explanation:

We are given the equation for (y), [y=x-5]

So we can implement that in all the places the (y) are in the other equation.

x+3(x-5)=9

x+3x-15=9

add 15 to each side

4x=24

Divide each side by 4

x=6

Now we can apply our (x) into one of the equations.

y=(6)-5

y=1

So our solution is (6, 1)

Answer:

x = 17

Step-by-step explanation:

Since 2 sides of the triangle are congruent then it is isosceles, so

The 2 base angles are congruent, both 29°, thus

11x - 65 = 180 - (29 + 29) = 180 - 58 = 122 ( add 65 to both sides )

11x = 187 ( divide both sides by 11 )

x = 17

The answer is x=4 or x=−10

Solutions:

(x + 3)² = 49

(x+3)(x+3)=49

x²+6x+9=49

(x-4)(x+10)

x-4=0 x+10=0

x=4 x=-10

Answer:

the answer would be 211

Step-by-step explanation:

you simply add the length and width together to find perimeter. since you have the total perimeter and the length you would instead subtract the two.

292-81= 211

Answer:

68m

Step-by-step explanation:

The perimeter  of a rectangle with length  and width  is given by the following.

P=21+2w

We need to find w when P=292 m  and l+78m .

Using these values in the equation above, we'll solve for w.

P=21+2w

292=2(78)+2w

292=156+2w

136=2w

68=w

Subtracting 156  from both sides

Dividing both sides by  2

So the width of the parking lot is 68m

Answer:

Answer:

Step-by-step explanation:

Answer:

y = 2x - 7

Step-by-step explanation:

The question is asking for slope-intercept form, y = mx + a.

Given:

(1, -5) and (9, 11)

Find the slope (m) between the two points:

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

x1 = 1

x2 = 9

y1 = -5

y2 = 11

m = ( 11 - (-5) )/(9 - 1)

= 16/8

m = 2

y = 2x + a

Use one of the two points to find a (I will use (1, -5)):

-5 = 2(1) + a

-5 = 2 + a

-7 = a

a = -7

y = 2x + (-7)

y = 2x - 7

Answer:

50.6
