1 true and false question = 1 / 2 chances
2 multiple choice question = 2/8
1/2 + 2/8 =
4/8 + 2/8 = 6/8.
6/8 = 3/4
you have a 75% chance of getting all 3 answers correct and getting a 100% on the quiz
hope this helps :D
No. 1/4 of an hour is 15 minutes..
15 minutes read every day for 15 days is 225 minutes, which is less than 500
the answer is 4.5 ft
Step-by-step explanation:
Step-by-step explanation:
Given that the two fugures in the question above are similar, it means they have the same shape, even though they are if different sizes, the ratio of their corresponding sides are proportional. Thus,
18/x = 8/2
Let's solve for x as required.
We have,
18/x = 8/2
=>Cross multiply:
18 × 2 = 8 × x
36 = 8x
=>Divide both sides by 8
36/8 = x
4.5 = x
x = 4.5 ft
For this case, the first thing we must do is define variables.
We have then:
x = Carli's bill
y = Angela's bill
We have then:
"their total bill was $ 109"
x + y = 109
"Carli went over her data limit on her phone, so her share of the bill was $ 15 more than Angela's"
x = y + 15
Answer:
A system of equations that represents this situation is:
x + y = 109
x = y + 15
Answer:
642 mm or 64.2 cm
Step-by-step explanation:
67cm-28mm
We need the same units
67 cm * 10 = 670 mm
670 mm - 28 mm
642 mm
We can convert back to cm by dividing by 10
64.2 cm
