Answer:
Length of the hypotenuse = 8.5 units
Step-by-step explanation:
Given the length of the sides of an isosceles right triangle to be 6units
Hint: an hypotenuse is the longest line
To solve this, we use Pythagoras rule
Hypotenuse^2 = adjacent ^2 + opposite ^2
Adjacent = opposite = 6
Let our hypotenuse to be a
a^2 = 6^2 + 6^2
a^2 = 36 +36
a^2 = 72
To get a, let's find the square root of 72
a = 8.485 unit
Therefore, the length of the hypotenuse = 8.5 units
Answer:
x > 453
Step-by-step explanation:
Because he died in 453, we want all values greater than 453. Use the > sign to express this.
<h3><u>
Answer:</u></h3>
Option: C is the correct answer.
$ 1.50 is the cost of 1 eraser.
<h3><u>
Step-by-step explanation:</u></h3>
Alicia bought a notebook and several erasers at the student store.
Let the cost of 1 eraser=$ x.
Now from the scatter plot we could see that when Alicia did not bought any eraser then her total cost =$ 2.
That means cost of a notebook=$ 2.
Now when she buys a notebook and two eraser then she pays=$ 5.
i.e.
Total cost=cost of notebook+ 2× cost of 1 eraser
Total cost=cost of notebook+2×x
i.e.
5=2+2x
⇒ 2x=5-2
⇒ 2x=3
⇒ x=1.5
Hence, cost of one eraser is:
$ 1.50

Answer:
x = 2
Step-by-step explanation:
Using Pythagoras identity in the right triangle
x² = 10² + 6² = 100 + 36 = 136 ( take the square root of both sides )
x = 
= 
= 2
