Answer:
54 minutes
Step-by-step explanation:
The sum of fractions is ...
2/5 + 3/20 + 1/3 = 11/20 +1/3 = (3·11 + 20·1)/(20·3) = 53/60
Then the 42 minutes devoted to English represents 1 - 53/60 = 7/60 of her study time.
Kaya's social studies time is 3/20 = 9/60 of her total, so the ratio of SS to Eng is ...
SS : Eng = (9/60) : (7/60) = 9 : 7
When we multiply the numbers in this ratio by 6, we find ...
SS : Eng = 54 : 42
Kaya spent 54 minutes studying social studies.
15 minutes is 25% of an hour. You can tell this because there are exactly 4 15 minute periods in one hour.
Hope this helped.
Answer:
By definition, the slope of a vertical line is undefined. Because the value of x is always equal to 4 it is never equal to 0 therefore there is no y-intercept.
Step-by-step explanation:
<span>Subtract 55 from 180 total degrees of a triangle to get 125.
Put 2x and x + 10 together...
3x + 10 = 125
Subtract 10 from both sides...
3x = 115
Divide by 3...
x = 38.3333
Now to find the measure of angle 2...
38.333(2) = 76.66666
Don't know if that's a multiple choice question or not, but that's what I got</span>
