The answer is B. obtuse, because obtuse angles are between 90° and 180°. Acute angles are between 0 and 90, right angles are 90° exactly, and straight angles are 180°. I hope this helps!
(50-(x*50))+(40-(y*40))+20= discounted with 2 coupons
110-(z*110)= the price with the total coupon.
I believe these are the correct answers
8.25/3 = $2.75 per ice cream
2.75 * 2 = $5.50
It would cost $5.50 for 2 ice cream
The answer is C. If you simplify the ratios in the table, they equal 3:5. You look at the examples, and divide both numbers in the ratios by this simplified porpotion. If the numbers are the smame as eachother after dividing, that is how you know your answer
Answer:
5^ -7 =1 / 5^7
Step-by-step explanation:
(5^2)-^2/ 5^3
We know that a^b^c = a^(b*c)
(5^2)-^2 = 5^(2*-2) = 5^-4
5^-4/ 5^3
We know that a^b /a^c = a^ (b-c)
5 ^ (-4-3)
5^ -7
If we don't want to use negative exponents
We know that a^ -b = 1/ a^b
1 / 5^7
