April invests $30,000, part at 6.5% annual interest and the balance at 4.2% annual interest. How much is invested at each rate if April receives a 1-year interest payment of $1662.50?

Answers

Answer:

$17500 at 6.5% and $12500 at 4.2%

Step-by-step explanation:

Given

Let x be the amount invested at 6.5%Then (30000 - x) is invested at 4.2%

The equation for the interest:

x*6.5/100 + (30000 - x)*4.2/100 = 1662.500.065x + 1260 - 0.042x = 1662.500.023x = 1662.50 - 12600.023x = 402.5x = 402.5/0.023x = 17500

So $17500 invested at 6.5% and $12500 at 4.2%

if you get this correct and solve this question step by step with a good explanation then i will mark you brainliest!

Answers

Answer:

v = 2/5    Or    v = 0.4

Step-by-step explanation:

12/5 = 6v

to isolate V divide both sides by 6

(12/5) : (6)= 6v : (6)

For the left side because there is a fraction when you devide you change it into multiplication, flipping the addent and quotient so you’ll have

12/5 * 1/6  (you semplify the cross numbers) you’ll have 2/5

on the right side the 6 cancel each other. Because 6/6 = 1. so you will have 1v which is v.

2/5 = v

or decimal form

0.4 = V

23^x=6
can someone show me how to solve this

Answers

23 to the power of x is equal to 6. Since the outcome is less than the number were multiplying then x is less than 1. This means X could be a negative number or a number between 0 and 1. When we multiply 23 to the power of a negative number the result will be 1/20 to the power of *the positive of the number we used*
I don’t know the exact formula used but 23 to power of negative 24 and 23 to the power of .6 are close to 6.

b. -1/2
c. 1/2
d. squr3/2​

Answers

Answer:

B -1/2

Step-by-step explanation:

The given trigonometric expression can be evaluated as -1/2.

What are trigonometric ratios?

The trigonometric ratios are defined for a right angled triangle.

The example of these ratios are sin, cos, tan, cosec, sec and cot.

The trigonometric ratios are useful in determining the heights and distances of the large objects.

The given trigonometric expression is as below,

cos(11π/21)cos(π/7) - sin(11π/21)sin(π/7)

Suppose, A = 11π/7 and B = π/7

Then, the given expression can be written as,

cosAcosB - sinAsinB

As per the trigonometric identity cos(A + B) = cosAcosB - sinAsinB.

Then, the given expression can be written as,

⇒ cos(11π/21)cos(π/7) - sin(11π/21)sin(π/7) = cos(11π/21 + π/7)

⇒ cos(2π/3) = -1/2

Hence, the exact value of the given expression is -1/2.

280 miles in all

Step-by-step explanation:

Step one:

given data

we are told that the team traveled 148miles south.

and also they traveled 132miles north.

Step two:

We are expected to solve for the total distance the team traveled

Hence total distance= 148+132= 280 miles in all

Note: the team;'s displacement is 148-138= 10miles in

two thousand ticketa are sold at a raffle for a chance to win a gaming computer system worth $1800. the tickets are sold for $2 each. if a person buys only one ticket what is the expected value for that ticket?round to the nearest cent if necessary

Answers

Answer:

The expected value of the ticket is -$1.10

Step-by-step explanation:

Here, we want to find the expected value of the ticket sales

We start by calculating the probabilities

The probability that someone wins the system is 1/2000

The probability that a person loses the system is 1999/2000

So the expected value will be;

(1/2000 * 1,800) - (1999/2000 * 2)

= 0.9-1.999 = -1.099

To the nearest cent, this is -1.10

Find the area of a circle with a radius of 5 feet. Round your answer to the nearest tenth. Find the area of a circle with a diameter of 56 millimeters. Round your answer to the nearest hundredth.

Answers

Case 1 :

Radius, r = 5 feet.

Area,

[tex]A=\pi r^2\\\\A = 3.14\times 5^2\ feet^2\\\\A = 78.5\ feet^2[/tex]

Case 2 :

Diameter, d = 56 mm.

So, radius, r = d/2 = 28 mm.

Area,

[tex]A = 3.14\times 28^2\ mm^2\\\\A = 2461.76\ mm^2[/tex]

Hence, this is the required solution.
