Does Anyone Know How To Solve This Problem?

Answers

Answer 1

Answer:

50, 130

Step-by-step explanation:

Since they are a linear pair they add to 180

z + ( 2.4z+10) = 180

Combine like terms

3.4z + 10 = 180

Subtract 10 from each side

3.4z+10-10 = 180-10

3.4z = 170

Divide each side by 3.4

3.4z/3.4 = 170/3.4

z = 50

2.4z + 10 = 130

Shakia buys a bunkbed originally priced at $119.99 at a discounted price of $71.99. What is the discounted percent? Round to the nearest whole number. Then write an equation that relates the markdown price y to the original price x.

Answers

Answer:

the discounted percentage is 40%, saving 48$

Step-by-step explanation:

The discounted price is as a result of the original price being reduced by 40% and the relation of the markdown price and the original is 0.8x = y.

The discount percentage can be found by:

= (Original price - Discounted price) / Original price x 100%

= (119.99 - 71.99) / 119.99 x 100%

= 48/119.99 x 100%

= 40%

The markdown price is as a result of 40% being deducted from the original price:

Original price - 20% of original price = Markdown price

x - (20% × x) = y

x - 0.2x = y

0.8x = y

In conclusion, the markdown percentage is 40% and the equation that shows it is 0.8x = y

Answer:

  a) $5176 periodic deposit

  b) $98,344 comes from deposits; $31,656 comes from interest.

Step-by-step explanation:

a) A suitable annuity formula can tell you the deposit required to achieve a particular future value.

  FV = P((1+r)^n -1)/r

For a future value of FV from a periodic payment of m for n periods compounded at rate r per period.

Here, FV = $130,000, r = 0.03, n = 19, so the payment P is ...

  P = FV·r/((1+r)^n -1)

  P = $130,000(0.03)/(1.03^19 -1) ≈ 5176.80

The periodic deposit is $5176.

__

b) So, 19 deposits of $5176 have a value of ...

  19 · $5176 = $98,344

This is the amount that comes from deposits.

The remaining amount, $130,000 -98,344 = $31,656, is the amount that comes from interest.

What is probability?

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

As shown above, a classic deck of cards is made up of 52 cards, 26 are black, and 26 are red.

Each color is split into two suits of 13 cards each (clubs and spades are black and hearts and diamonds are red).

Each suit is split into 13 individual cards (Ace, 2-10, Jack, Queen, and King).

Then the probability of drawing a 5 of one suit will be given as

Total event = 52

Favorable event = 4 {5 club, 5 spade, 5 heart, and 5 red}

Then we have

Take the square root of 25 to factor this equation out.

The equation will look like this:

The sum of two consecutive integers is 99. Find the integers

Answers

Answer:

48

Step-by-step explanation:

The consecutive numbers will be x and x + 1. Then write out the equation 2x + 1 = 99

Collect like terms

2x = 99 - 1

2x= 98

divide both sides by 2

x = 49

Answer:

49,50

Step-by-step explanation:

N+N+1=99   add the N's together

2N+1=99      subtract 1 from both sides

2N=98         divide 2 by 98

N=49           add the 1 from before

49+1=50

49,50 are the consecutive integers

y=20

The  Value of x and y is 10 and 20 respectively.

 Given that,

                     [tex]y = 2x\\y = 5x - 30[/tex]

Substitute y = 2x in second equation.

            [tex]2x=5x-30\\\\5x-2x=30\\\\3x=30\\\\x=30/3=10[/tex]
