Answer:
113.09733
Step-by-step explanation:
It is 113.09733 because
the formula for area is Pi(Radius)^2
And 6^2 is 36.
36 x Pi is 113.09733
Answer:
140
Step-by-step explanation:
The ratio of similitude is 6/5, so the ratio of the areas is (6/5)² = 36/25.
So, the area of XYZ is 100(36/25) = 144, which is about <u>1</u><u>4</u><u>0</u>
Factors are (3x + 5) and (x - 2). Zeros are -5/3 and 2.
Step-by-step explanation:
- Step 1: Given quadratic equation 3x² - x = 10 ⇒ 3x² - x - 10 = 0
- Step 2: Use factoring method (product and sum rule) to find factors and zeros. So the equation can be written as below.
⇒ 3x² - 6x + 5x - 10 = 0
⇒ 3x(x - 2) + 5(x - 2) = 0
⇒ (3x + 5)(x - 2) = 0 These are the factors of the equation.
- Step 3: Find zeros by equating the factors to 0.
⇒ 3x + 5 = 0 and x - 2 = 0
⇒ x = -5/3 and 2
Answer:
Step-by-step explanation:
Given that prices for a pair of shoes lie in the interval
[80,180] dollars.
Delivery fee 20% of price.
i.e. delivery fee will be in the interval [4, 9]
(1/20th of price)
Total cost= price of shoedelivery cost
Hence f(c) = c+c/20 = 21c/20
The domain of this function would be c lying between 80 to 180
So domain =[80,180]
---------------------------------
Amount to be repaid = 42 dollars
Once he received this amount, the price would be
105+42 =147
But since price range is only [21*80/20, 21*180/20]
=[84, 189]
Since now Albert has 147 dollars, he can afford is
[80,147]
Answer:
12 times
Step-by-step explanation:
Without the discount pass, the bus fare is $1.25. The monthly discount pass is $15.00. 15 ÷ 1.25 is 12. So, the bus would have to be used 12 times in a month so that the total monthly cost without the discount pass is the same as the total monthly cost with the discount pass.
