Its 11/12 , you need to divide the "wanted results" (every dog which is either black, with spots or both ) by every every possible result ( all dogs ). so 11/12=0.92
Answer:
6y^2+2y
Step by step explanation:
2y*(y+3)+4y*(y-1)
Distribute 2y through the parentheses
2y^2+6y+4y*(y-1)
Distribute 4y through the parentheses
2y^2+6y+4y^2-4y
Collect like terms
6y^2+6y-4y
Collect like terms
6y^2+2y
Answer
6y^2+2y
(2) So we know Ethan uses 1/4 cup of milk for his cake. And if he needs to make 3 times the amount of 1 cake, he'll make 3 cakes today. So we multiply the amount of cakes (3) by the amount of milk needed (1/4)
3 * 1/4 = 3/4
Ethan will need 3/4 cups of milk.
(3) We know Isabella need's 2/5 of a gallon of the food to make 1 gallon.
She want's to make 5 gallons, so like the other problem, we multiply the amount of gallons (5) by the amount of food needed (2/5):
5 * 2/5 = 10/5 = 2/1.
Isabella will need 2 gallons of food.
There are two prime numbers between 20 and 30: 23 and 29.
To find the percentage each number is of 125, you’d divide the number by 125 and move the decimal in the answer 2 places to the right to turn it to percentage notation (from decimal notation), so you’d solve 23/125 and 29/125.
23/125= .184
Moving the decimal two places to the right makes this 18.4%
29/125= .232
Moving the decimal two places to the right makes this 23.2%
X has two possible values of which you are to pick/use only one: 18.4 and 23.2
130 * 3 equals 390 so 390 is your answer
