If a thousand dollars is put into a bank account each year the account earns 7% simple interest in 4 years how much interest would it have gained

Answers

Answer:

$280

Step-by-step explanation:

According to the problem, calculation of the given data are as follows:

Principal amount (P) = $1,000

Rate of interest (r) = 7%

Time period (t) = 4 years

Here we use simple interest formula to calculate interest after 4 years.

I = P × r × t

By putting the value, we get

I = $1,000 × 7% × 4

= $70 × 4

= $280

Step-by-step explanation:

From the equation y−3=−2(x+1), identify the slope and a point on the line.

Answers

Answer:

slope = - 2, point on line = (- 1, 3 )

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 3 = - 2(x + 1) ← is in point- slope form

with slope m = - 2 and (a, b ) = (- 1, 3 )

The slope of equation y−3=−2(x+1) is -2.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

y−3=−2(x+1)

Using Slope- Intercept form

y= mx + b

So, the slope for the equation is -2.

Hence, the slope is -2.

Cindy has $75. She goes to the store and buys a set of markers for $6, a box of pencils for $12, and 4 notebooks. The notebooks all cost the same. Cindy has $39 left when she leaves the store.

Part A. Write an equation to determine the price of one notebook. Let n represent the cost of the notebook.






Part B. What is the price of each notebook?

Answers

A: We want to take away all the useless numbers that don’t relate to the notebook first, and subtract them.
75 - 6 = 69
69 - 12 = 57
There, now we have to subtract the amount of money she has when she leaves from the total amount spent right now.
57 - 39 = 18
To get the amount spent on all four notebooks, all you need to do is divide by 4
18 / 4 = $4.50
And that’s your answer!

B: $4.50

If the surface area of a sphere is 144pi square centimeters, what is the length of the radius of the sphere, in centimeters

Answers

Answer:

6cm

Step-by-step explanation:

The formula for the surface area of a sphere = 4πr²

From the Question, we are given:

The surface area of a sphere = 144pi square centimeters = 144π cm²

The length of the radius of the sphere, in centimeters is calculated by:

4πr² = 144π

Divide both sides by 4π

4πr²/4π = 144π/4π

r² = 36

Square root both sides

√r² = √36

r = 6cm

Therefore, the length of the radius of the sphere, in centimeters is 6 centimeters.

The surface area of the shoe box is,

⇒ SA = 418 square inches

We have to given that,

A shoe box has a length of 14.5 inches, a width of 7 inches, and a height of 5 inches.

Since, We know that,

Surface area of cuboid is,

SA = 2 (lw + lh + hw)

Here, we have;

Length = 14,5

Width = 7 inches

Height = 5 inches

Hence, We get;

The surface area of the shoe box is,

SA = 2 (14.5 x 7 + 14.5 x 5 + 5 x 7)

SA = 2 (101.5 + 72.5 + 35)

SA = 2 (209)

SA = 418 square inches

Thus, The surface area of the shoe box is,

⇒ SA = 418 square inches

2x+3y = 18

3y = 18-2x ..... subtract 2x from both sides

3y = -2x+18

y = (-2x+18)/3 .... divide both sides by 3

y = (-2x)/3 + 18/3

y = (-2/3)x + 6

Evaluate (2.4x10^4) (4.5x10^3)

Answers

Answer:

108000000x^2

Step-by-step explanation:

The given expression (2.4 × 10⁴) (4.5 × 10³) becomes 1.08 × 10⁸ after performing the operations.

To evaluate the expression (2.4 × 10⁴) (4.5 × 10³), we use the properties of exponents.

When multiplying numbers written in scientific notation, we multiply the coefficients and add the exponents.

(2.4 × 10⁴) (4.5 × 10³) = (2.4 × 4.5) × (10⁴ × 10³)

= 10.8 × 10⁷

Next, we simplify the result by adding the exponents since the base (10) is the same:

10.8 × 10⁷ = 1.08 × 10⁸

Therefore, the final result of the expression is 1.08 × 10⁸.
