Answer:

Yes

Step-by-step explanation:

A right triangle's formula, according to Pythagorean's Theorem, is a² + b² = c². a and b are the two legs, and c is the hypotenuse. To solve, we must substitute the variables with the given measurements.

9² + 12² = 15²

Let's now solve:

81 + 144 = 225

225 = 225

The formula works out in the end, so it is a right triangle!

(7.RP.3) When invested at an annual interest rate of 6% an account earned $180.00 of simple interest in one year. How much money
tresset_1 [31]

Answer:  f) $3,000


Step-by-step explanation:

Given: Simple interest amount S.I.= $180.00

The rate of interest annually= 6%

In decimal , the rate of interest annually r = 0.06

Time period t = 1 year

Let 'P' be the principal amount invested in account.

The formula to calculate simple interest is as :-

\text{Simple interest }=Prt

\\\Rightarrow180=P(0.06)\times1\\\\\Rightarrow\ P=\frac{180}{0.06}\\\\\Rightarrow\ P=\$3000

Hence, the principal amount invested in account = $3000

At the ritz concert tickets for adults cost $6 and tickets for students cost $4. How many of each ticket were purchased if 480 t
Anni [7]

Answer: the number of adult tickets is 210

The number if student tickets is 270

Step-by-step explanation:

Let x represent the number of adult tickets that were purchased.

Let y represent the number of student tickets that were purchased.

At the ritz, concert tickets for adults cost $6 and tickets for students cost $4. If the cost of total tickets purchased is $2340, then,

6x + 4y = 2340 - - - - - - - -1

Total number of tickets purchased is 480. This means that

x + y = 480

x = 480 - y

Substituting x = 480 - y into equation 1, it becomes

6(480 - y) + 4y = 2340

2880 - 6y + 4y = 2340

- 6y + 4y = 2340 - 2880

-2y = - 540

y = - 540/-2 = 270

x = 480 - 270

x = 210
