Answer:
$9.60
Step-by-step explanation:
<em>Find the Discount </em>
The sale is 85% off, and the chalkboard is $64. To find the discount, multiply 85% and 64
85%*64
Convert 85% to a decimal by dividing by 100, or moving the decimal 2 spots to the left
85/100=0.85
85. --> 8.5--> .85
0.85*64=54.4
$54.40 is the discount
<em>Find the price </em>
Now we now the discount is $54.40. We have to subtract the discount from the regular price to find the sale price
regular price - discount
64-54.40
9.6
$9.60 is the sale price
A standard numbered cube (die) has six faves numbered 1, 2, 3, 4, 5, 6
Three are even 2, 4, 6 and three are odd 1, 3, 5
P(even) = 3/6
P(odd) = 3/6
So for a fair die an odd number is equally likely as an even number
The answer is A) A number that is divisible by 10 is also divisible by 5 because all factors of 10 are also factors of 5.
hope this helps !
We use the Pythagorean theorem to determine if the side lengths given will result to either a right, acute, or obtuse triangle.
a = 7 ; b = 24 ; c = 26
a² + b² = c² ⇒ right triangle
a² + b² > c² ⇒ acute triangle
a² + b² < c² ⇒ obtuse triangle
7² + 24² = > < 26²
49 + 576 = > < 676
625 < 676 OBTUSE TRIANGLE
Variables that are the same are added so 4a and 2a are added making it 6a. Now you have 13+6a=3a+1. Now you have to move things. Move the 3a to the other side making it a negative. So now you have 13+6a-3a=1. You now have 13+3a=1. So move the 13 to the other side. 3a=13-1. Which makes 3a=12. All you have to do now is 12 divided by 3. So a=4
