The exact value of the y in the similar right triangle is 2.2360679775 units

<h3 /><h3>How to find the side of a triangle?</h3>

The triangles are similar.

Similar triangles have corresponding sides of equal ratio.

The corresponding angles of similar triangle are equal.

Therefore, using similar ratio,

y / 5 = 1 / y

cross multiply

y × y = 5 × 1

y² = 5

square root both sides

y = √5

Therefore,

y = 2.2360679775 units

Answer:

Step-by-step explanation:

Givens

Observe the small triangle at the right. The smallest side is one.

The hypotenuse is y

In the largest tringle, the hypotenuse is 5

The smallest side is y

You can set up a ratio for this situation

Equation

smallest side -  smallest triangle       Largrest triangel -- largest side

============================         =========================

hypotenuse - smallest triangle            hypotenuse -- largest triangle

1/y = y / 5                   Cross Multiply

Solution

y^2 = 1*5                    Take the square root of both sides.

√y^2 = √5

y = √5

or

y =

9(2w−y)=21w−9y Solve for y
valentinak56 [21]

9(2w−y)=21w−9y

First you multiply the numbers in the parenthesis by 9

18w-9y=21w-9y

subtract. 21w-18w=3w

-9y=3w-9y

add. -9y+9y=0

0=3w

divide.

0=w

Final answer is 0.

you want to deposit $15,000 in a bank at an interest rate of 7% per year what is the future value of this money after 3 years
Assoli18 [71]
AMOUNT DEPOSITED: $15k ($15,000)
INTEREST RATE PER YEAR: 0.07% (7%)

STEPS:
→Multiply the amount deposited ($15k) by the interest rate per year (7%).
15,000 * 0.07
= $1,050 (interest earned in 1 year)

→Multiply the interest earned from the first year ($1,050) by the amount of years that you want to calculate (3 years)
$1,050 * 3
=3,150 (interest earned in 3 years)

→ Add the interest earned (in 3 years, in this particular equation) to the amount that you deposited ($15k)
$15,000 + $3,150
=$18,150

FINAL ANSWER: $18,150
