An investment of $5000 earns $6000 simple interest in 12 years. Calculate the interest rate.Please show working out

Answers

Answer 1
Answer:

Answer:

10%

Step-by-step explanation:

To solve this problem we can use a modified version of the simple interest formula which is shown below:

r=(I)/(Pt)

I = interest amount

P = principal amount

t = time (years)

Lets plug in the values:

r=(6000)/((5000)(12))

r=0.1

The last step is to convert 0.1 into a percent:

0.1(100) = 10

The interest rate is 10%

Sam is moving into a new apartment. Before he moves in, he has to pay his landlord the first month's rent and a security deposit 1.5 times that of the monthly rent. If he pays the landlord $3275 before he moves in, what is the monthly rent?

Answers

The monthly rent will be $1310

Let the monthly rent be represented by x.

Since the security deposit is 1.5 times that of the monthly rent, then the security deposit will be: = (1.5 × x) = 1.5x

Then the monthly rent will be calculated thus:

(1.5x + x) = $3275

2.5x = $3275

Then, we'll find the value of x

x = $3275/2.5

x = $1310

Therefore, the monthly rent will be $1310.

x = monthly rent
x + 1.5x = 3275
2.5x = 3275
x = 3275/2.5
x = 1310 <== rent

1.5(1310) = 1965 -- security deposit


check...
1310 + 1965 = 3275
3275 = 3275 (correct)

so his monthly rent is : $ 1310

Jacob is showing his steps to solve the expression −27.8 ÷ 1 over 7.In which step did Jacob make an error?

Step 1: −27.8 ÷ 1 over 7
Step 2: −27.8 ⋅ 7

Step 3: −194.6

Step 1

Step 2

Step 3

There is no error.

Answers

Answer:

D.There is no error.

Step-by-step explanation:

We are given that Jacob is showing his steps to solve the expression

-27.8/(1)/(7)

We have to find the error in Jacob steps in which he makes error

Jacob writes his first step

Step:1 -27.8/ (1)/(7)

Jacob's first step is true.

We know that if we changes  divide sign of term  into multiply then the the term which is write on right side of divide sign reciprocal. Therefore,

Step:2-27.8*7=-27.8\cdot 7

Hence, Jacob's second step is right.

Now ,  we multiply -27.8 with 7 then we get

Step:3 -27.8\cdot7=-194.6

Hence, Jacob's third step is also right.

Therefore, Jacob makes no error in his steps.

Hence, Option D is true.

There is no error, Jacob did everything right :)

A cube is sliced diagonally, containing two vertices, and perpendicular to the base, as shown below. Which figure best represents the cross-section parallel to the slice?

Answers

Half of a square (cube) is a triangle diagonally.

What form is the diagonal cross-section of a dice?

Slicing the cube with this aircraft creates a moving segment that may be a triangle, but not an equilateral triangle; it's miles a scalene triangle. note that if any two decided-on factors are equidistant from the original vertex, the move section might be an isosceles triangle.

How do you discover the diagonal attitude of a cube?

Use the trigonometric formula c^2 = a^2 + b^2 – 2ab cos C to resolve the unknown perspective of this triangle. C=1 and each a and b are equal to √three/2. Plugging those values into the equation, you'll determine that the cosine of your unknown angle is 1/three.
