Elena's father put $460 into a savings account for her. The account pays 2.5% simple interest each year. If he neither adds nor withdraws
money from the account, how much interest will the account earn after 4 years? Round to the nearest cent.

Answers

Answer:

$46

Step-by-step explanation:

Give that Elena's father put $460 into a savings account.

So, the principal amount, P= $ 460

Yearly simple interest , R= 2.5% = 0.025

Time, t = 4 years.

The interest, I, for the principal amount, P,  at the rate of R yearly, after t years,

[tex]I= P\times R \times t[/tex]

By using the given values, we have

[tex]I=460\times 0.025 \times 4 = 46[/tex]

Hence, the account will earn $46.

Answer:

x = 35      y = 82

Step-by-step explanation:

all triangles add up to 180

the tick mark shows that 2x = y - 12

2x + 2x + 40 = 180

4x + 40 = 180

4x = 140

x = 35

y - 12 + y - 12 + 40 = 180

2y - 24 + 40 = 180

2y + 16 = 180

2y = 164

y = 82

Check:

40 + 2(35) + (82 - 12) = 180

The graph below shows the distance, y, in miles, of a bird from its nest for a certain amount of time, x, in minutes:

Graph titled Distance Vs Time is shown with Time in minutes along the x axis and Distance from Nest in miles along the y axis. The scale on the x axis shows the numbers 0 to 25 at increments of 5, and the scale on the y axis shows the numbers 1 to 8 at increments of 1. A straight line joins the ordered pairs 0, 3 and 5, 4 and 10, 5 and 15, 6 and 20, 7.

Based on the graph, what is the initial value of the graph and what does it represent? (1 point)

a
3 miles per minute; it represents the speed of the bird

b
0.2 mile per minute; it represents the speed of the bird

c
0.2 mile; it represents the original distance of the bird from its nest

Step-by-step explanation:

The quadratic equation is as follows :

The solution of a quadratic equation [tex]ax^2+bx+c=0[/tex] is given by :

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]

Equation (1) can also be written as follows :

Here, a = 7, b = -1 and c = -9

[tex]x=\dfrac{-b+ \sqrt{b^2-4ac} }{2a}, x=\dfrac{-b-\sqrt{b^2-4ac} }{2a}\\\\x=\dfrac{-(-1)+\sqrt{(-1)^{2}-4(7)(-9)}}{2(7)}, \dfrac{-(-1)-\sqrt{(-1)^{2}-4(7)(-9)}}{2(7)}\\\\x=1.20\ s, -1.06\ s[/tex]

A) Converse and Inverse B) Inverse and Contrapositive C) Conditional Statement and Converse D) Conditional Statement and Contrapositive

Answers

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect.

Two or more lines which have no intersections but are not parallel, known as skew lines.

Option D is correct.

Conditional Statement: If two lines are parallel, then they do not intersect.

Converse: If two lines do not intersect, then they are parallel.

Inverse: If two lines are not parallel, then they intersect

Contrapositive: If two lines intersect, then they are not parallel.

Thus,  option (D) Conditional Statement and Contrapositive , is correct.

Converse and Inverse are false because skew lines are a type of lines which are neither parallel nor intersecting in 3D

Solve this equation.
24 + 0.44x = 19 + 1.69x

Answers

Answer:

x = 4

Step-by-step explanation:

24 + 0.44x = 19 + 1.69x

24 + 0.44x - 1.69x = 19

-1.25x = 19 - 24

-1.25x = -5

x = 4

Step-by-step explanation:

24 + 0.44x = 19 + 1.69x

24 - 19 = 1.69x - 0.44x

5 = 1.25x

1.25x = 5

Solve: 2.3 = v + 0.47 v = _____

Answers

Answer:

2.3=v+0.47v=

We move all terms to the left:

2.3-(v+0.47v)=0

We add all the numbers together, and all the variables

-(+1.47v)+2.3=0

We get rid of parentheses

-1.47v+2.3=0

We move all terms containing v to the left, all other terms to the right

-1.47v=-2.3

v=-2.3/-1.47

v=1+0.83/1.47

Answer:

[tex]v = 1.564[/tex]

Step-by-step explanation:

[tex]1v + 0.47v = 2.3[/tex]

If c varies diráctly as (1 + 1) and c= 8, when r = 3, calculate the value ofr when c= 20.
(4marks)​

Answers

c = k(r + 1)

8 = k(3 + 1)

8 = 4k

8/4 = k

2 = k

c=2(r + 1)

When c = 20, then

20 = 2(r + 1)

20 = 2r + 2

20 - 2 = 2r

18 = 2r

18/2 = r

9 = r

Therefore, the value of r is 9 when c is 20.
