3. Jen’s parents buy a tablet for her to use in school. Of the $1500 cost, her parents expect her to pay back $1000 one year lat
NNADVOKAT [17]

Answer:

<h3>33.3%</h3>

Step-by-step explanation:

Using the formula for calculating simple interest as shown;

Simple Interest = Principal * Rate *Time/100

Principal = Cost of tablet = $1500

Interest after one year  =  $1500-$1000 = $500

Time = 1year

Substituting this values into the formula;

500 = 1500*rate*1/100\\Cross\ multiplying\\50,000 = 1500 * rate\\Rate = 50,000/1500\\Rate = 33.3%

The interest rate that her parents assumed is 33.3%

Pilar and Ravi start at opposite ends of a 55-mile bike trail. They start riding their bikes toward each other at the same time.
Lynna [10]

Answer:

Ravi’s average speed is 7 miles per hour

Step-by-step explanation:

In this question, we are tasked with calculating what Ravi’s average speed was.

We must know that the term average speed is mathematically equal to Total distance/ Total time

We already have the time of 3 hours, what is needed is the distance.

From the question, we can see that they met at the point where Pilar had travelled 55 miles. What this means is that Ravi would have traveled (55-34) miles to this point since they are coming in opposite direction. This means that Ravi had traveled 21 miles

Thus his average speed is 21 miles/ 3 hours = 7 miles per hour

vagabundo [1.1K]

Answer:

114

Step-by-step explanation:

To evaluate f(7) substitute x = 7 into f(x), that is

f(7) = 268 - 22(7) = 268 - 154 = 114

A triangle has sides with lengths of 7 feet, 15 feet, and 17 feet. is it a right triangle?
aksik [14]
To test if this is a right triangle, let's test these side lengths with the Pythagorean Theorem.

a^2 + b^2 = c^2

c is the hypotenuse, the longest side of a right triangle.
a and b are the legs of the right triangle.

a = 7
b = 15
c = 17

7^2 + 15^2 = 17^2 ?

49 + 225 = 289 ?

274 ≠ 289

Thus, this triangle is not a right triangle since it does not satisfy the Pythagorean Theorem.

Have an awesome day! :)
