Play ground 70% (TOTAL)
books 30% (TOTAL)
60% of the 70% are boys
20% of the 30% are boys
Does that sound about right for a start?
3 oranges / 4 friends = 3/4 orange for each of them, or 0.75 orange each
(You can check the answer by saying, if each of them get 3/4 of an orange, then multiplying that by the 4 friends should give me the 3 oranges. 3/4 x 4 = 3, so it's correct).
Answer:
About 22.7 millions
Step-by-step explanation:
Latin America 58%
App. 39.1 million = 39,100,000
People were born in Latin America:
0.58 x 39100000 = 22,678,000
Round to the nearest tenth million = 22.7 millions
Answer:
a. 55 hours
b. 1.9 degrees C
Step-by-step explanation:
This means for each hour the temperature drops 0.08. This is the expression 0.08x where x is number of hours.
a.) If the temperature has dropped 4.4, then 4.4 = 0.08x. Solving for x will give the number of hours it takes to drop 4.4.
4.4 = 0.08x
4.4 / 0.08 = x
55 = x
b.) If the temperature after 55 hours and dropping 4.4 is -2.5, then the temperature at the start would be -2.5 + 4.4 = 1.9. The temperature at noon was 1.9 degrees celsius.
Answer:
x=−3 or x=5
Step-by-step explanation:
x2−2x−15=0
Step 1: Factor left side of equation.
(x+3)(x−5)=0
Step 2: Set factors equal to 0.
x+3=0 or x−5=0
x=−3 or x=5
