In the past you paid $800 per month to rent your apartment. You now pay $900 per month for your rent. What is the percent increase in your rent?

Answers

Answer:

Percent increase in rent is 12.5%

Step-by-step explanation:

Given:

In past the rent you paid $800 per month to rent your apartment.

i.e, Original rent paid = $ 800

You now pay $900 per month for your rent.

i.e New rent paid = $900

Increase in the rent is= New rent - Original rent= $900 -$800 =$100.

To find the percent increase in rent.

Percent increase is equal to Divide the increase by the original number and multiply the answer by 100.

i.e,

$Percent Increase = (Increase in rent)/(Original rent ) * 100$

then;

$Percent Increase = (\$ 100)/(\$ 800) * 100$

Simplify:

$Percent Increase = 12.5\%$

therefore, the percent increase in your rent is 12.5%

12.5% the difference is $100 write a proportion, 100 = x800 100 differencece = xoriginal 100

Which letter in the word happy has an order 2 rotational symmetry

Answers

The letter H is the only one in the word "happy" that has the rotational simmetry on the order of two. In fact, if you rotate the letter H 180° clockwise or counterwise, it will still look the same; it is called "on the order of two", exactly because you've rotated it 180° (two rotations of 90°).

Answer

Letter H

Explanation
The order of symmetry is the number times an object appears exactly the same when rotated about a certain axis.
From the word HAPPY, only letter H will have 2 order of symmetry.
When rotated at 180°, It will look exactly the same.
A, P, P and Y have only 1 order of symmetry.

(a) 3x + 7y = 13, 5x + 2y = 12
How do i solve this linear equation using substitution method??

Answers

Answer:

x= 2, y= 1

Step-by-step explanation:

First label the 2 equations:

3x +7y= 13 -----(1)

5x +2y= 12 -----(2)

Make x or y the subject of formula for one of the equation so that we can substitute its value into the 2nd equation.

Here, I am making y the subject of formula in the 2nd equation.

5x +2y= 12

2y= 12 -5x

$y = 6 - (5)/(2) x$ -----(3)

Substitute (3) into (1):

$3x + 7(6 - (5)/(2) x) = 13$

Expand:

$3x + 42 - (35)/(2) x = 13$

Bringconstantstooneside:

$3x - (35)/(2) x = 13 - 42$

Simplify:

$- (29)/(2) x = - 29$

Multiplyby-2onbothsides:

$- 29x = - 58$

Divideby-29onbothsides:

x=2

Substitute x=2 into (1):

3(2) +7y= 13

7y +6= 13

7y= 13 -6 (-6onbothsides)

7y= 7

y= 7 ÷7

y= 1

What is the image point of (3, -3) after a translation left 3 units and up 4 units?.

Answers

The imagepoint of (3, -3) after a translation of $(-3, 4)$ is $(0,1)$ .

Determination of the coordinates of resulting point after translation

Geometrically speaking, a translation is determined by following formula:

$V'(x,y) = V(x,y) + T(x,y)$ (1)

Where:

$V(x,y)$ - Original point
$T(x,y)$ - Translation vector
$V'(x,y)$ - Resulting point

If we know that $V(x,y) = (3, -3)$ and $T(x,y) = (-3, 4)$ , then the coordinates of the resulting point are, respectively:

$V'(x,y) = (3, -3) + (-3, 4)$

$V'(x,y) = (0, 1)$

The imagepoint of (3, -3) after a translation of $(-3, 4)$ is $(0,1)$ . $\blacksquare$

James is looking into life insurance. He currently makes $50,000 a year and has two children, ages 15 and 11. How much coverage and how long a term of life insurance would you recommend to James?

Answers

The coverage amount is $500,000

The recommended term of life insurance is 10-year term.

Based on the information given i would recommend insurance coverage amount of $500,000 and a term of life policy of 10-year term.

James will need a coverage amount of $500,000 until the two children are financial independent and can cater for themselves.

Using a long term policy of 10 years term of life insurance is recommended as the older will be 25 years and the youngest will be 21 years by then.

Coverage insurance amount:

Insurance coverage=Salary× Term of life

Insurance coverage=$50,000×10 year

Insurance coverage=$500,000

Inconclusion:

The coverage amount is $500,000

The recommended term of life insurance is 10-year term.

Step-by-step explanation:

If James wants to cover both of his children at his current salary until they both can support themselves on their own, he would need a 10-year term policy (if the youngest moves out when he/she is 21) with a face value of $500,000 (current salary-$50,000*10 years).
