Answer:
b. 6¹⁰ / 7⁶
Step-by-step explanation:
(6⁵/7³)²
6 × 6 × 6 × 6 × 6 = 7776
7 × 7 × 7 = 343
(7776/343)²
7776²/343²
7776 × 7776 = <u>60.466.176</u>
343 × 343 = <u>117.649</u>
6¹⁰/7⁶
6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 = 60.466.176
7 × 7 × 7 × 7 × 7 × 7 = 117.649
6¹⁰ = 7776²
7⁶ = 343²
= <u>b</u><u>.</u><u> 6¹⁰ / 7⁶</u>
Answer:
11 tickets
Step-by-step explanation:
1. write an equation:
First, variable x symbolizes the number of adults who bought tickets. And variable y symbolizes the number of students.
If each adult paid $6, and each student paid $4, and the total dollars you've collected is 104, this is how we'll write our equation:
6x + 4y = 104
2. we can write another equation based on this information: "You sold 21 tickets". Which concludes that the number of tickets adults and students had paid for equals the number of tickets you've sold:
x + y = 21
3. now, we've got two equations. Let's compensate:
x + y = 21
x = 21 - y
6x + 4y = 104
6 (21 - y) + 4y = 104
126 - 6y + 4y = 104
-6y + 4y = -22
-2y = -22
y = -22 / -2
<u>y = 11</u>
So the number of student tickets is <u>11</u>.
Answer:
Step-by-step explanation:
The total length of triangle is 40 in. The length of the right triangle is the total length divided by 2 which 40/2 = 20.
We have 2 right triangles. We can use the pythagorean theorem to solve for x.
a^2 + b^2 = c^2
x^2 + 20^2 = 25^2
x^2 + 400 = 625
- 400 - 400
x^2 = 225
x = 15
