Answer:

y=8.9

Step-by-step explanation:

To solve this problem, we have to use the pythagorean theorem.

the formula for the pythagorean theorem is a²+b²=c²

(8)²+(y)²=(12)²

64+y²=144

y²=144-64

y²=80

y=√80

y=4√5

y=8.9

hope this helps!!

Ede4ka [16]

Answer:

<u>The retail price of the car is US$ 10,024 Rounding to the next whole</u>

Step-by-step explanation:

1. Let's check the information given to us to answer the question correctly:

Mark up the purchase price = 17.4%

Price of purchase of the car = $ 8,538

2. What is the retail price of the car at this dealership?

For calculating the retail price of the car, we will use the Rule of Three Simple, this way:

x = retail price of the car

x * 1 = 8,538 * 1.174

x = 10,023.61

<u>The retail price of the car is US$ 10,024 Rounding to the next whole</u>

Answer:

$8,000

Step-by-step explanation:

Let the store earned $x in December.

Therefore,

Money spent to buy new inventory =\frac{1}{4} x

Remaining money = x - \frac{1}{4} x =\frac{3}{4} x

Money used to pay bills =\frac{1}{2} \times \frac{3}{4} x=\frac{3}{8} x

Money still left over = $3,000

Total money earned in December = \frac{1}{4} x+ \frac{3}{8} x+3,000

\therefore x= \frac{1}{4} x+ \frac{3}{8} x+3,000

\therefore x= \frac{2}{8} x+ \frac{3}{8} x+3,000

\therefore x= \frac{5}{8} x+ 3,000

\therefore x- \frac{5}{8} x=3,000

\therefore \frac{8x-5x}{8} =3,000

\therefore \frac{3x}{8} =3,000

\therefore x =3,000\times \frac {8}{3}

\therefore x =1,000\times 8

\therefore x =\$8,000

Thus, total money earned in December is $8,000.

A child throws a water balloon down out of a window . Substitute 0 for h into the equation h=-16t^2 - 10t+6 To determine how man
Igoryamba

Answer:

t = 3/8 seconds

Step-by-step explanation:

h=-16t^2 - 10t+6

h= 0 when it hits the ground

0=-16t^2 - 10t+6

factor out a -2

0= -2(8t^2 +5t -3)

divide by -2

0 = (8t^2 +5t -3)

factor

0=(8t-3) (t+1)

using the zero product property

8t-3 = 0    t+1 =0

8t = 3         t= -1

t = 3/8     t= -1

t cannot be negative  ( no negative time)

t = 3/8 seconds
