Step-by-step explanation:
1. 3 and 2 are complementary because when you add them up, they give a toral of 90°.
2. As you may tell from the picture, and that they stated it in the question, angles 1 and 2 are added and they give a total of 90°.
3. If we consider that angle 3 is somewhat equal to angle 1, then the statement is true.
4. As I mentioned, if angle 1 and angle 3 are equal, then the statement is also true.
5. It was kind of proven above that angle 1 and angle two are similar, so this is true.
6. Like option 5, this is also the same thing.
I hope it helped!
Answer:
9
Step-by-step explanation:
For each pizza variety, Daniel can choose 18 different toppings. Therefore, for 23 pizza varieties, Daniel can choose from 23 * 18 = 414 different combinations of varieties and toppings.
For each pizza size, Daniel can choose from 414 different combinations of varieties and toppings. Therefore, for n pizza sizes, Daniel can choose from n * 414 = 3726 combinations
414n = 3726
divide both sides by 414 to isolate the n
n = 9
9x^4 -225y^8
= 9(x^4 - 25y^8)
= 9(x^2 + 5y^4)(x^2 - 5y^4)
A gallon of gasoline cost 30 cents in 1960 an
$1.30 in 1980
percent increase in the price = ?
first we have to convert cents into dollars so that both amounts have to be in same unit
30 cents = $0.3
increase in gasoline cost = $1.30 - 0.3 = $1
now for calculating percent increase divide this with the new amount and than multiply with 100
percent increase = ($1 / $1.30) x 100 = 76.92% = 77% approx.
so, there is 77% increase in the price of gasoline
Take the cost of the item. Subtract how much you already paid from the cost of the item. Then boom! You got your answer. Hope I helped.
