Answer:
6 minutes
Step-by-step explanation:
Mr Crenshaw checks at a rate of 1/10 and Mr. Aguirre checks at a rate of 1/15.
If they work together, they will be checking at a combined rate of:
1/10 + 1/15 = [3(1) + 2(1)]/30
= 5/30 = 1/6
Their combined rate is 1/6 which means they check one set in 6 minutes
Answer:
62°
Step-by-step explanation:
In an isosceles triangle, angle opposite to equal sides are equal.
So according to angle sum property :
x + x + 56 = 180
2x + 56 = 180
x = 180 - 56 /2
x = 62°
1. You would add 5 to -14, getting -9, which leaves you with 3x=-9. You would then divide -9 by 3, leaving you with x=-3.
2. First, subtract 22 from 10, getting -12=-2c. Next divide -12 by -2, leaving you with 6=c.
3. Add 17 to 18 to get 35=-5b. Then divide 35 by -5, leaving you with -7=b.
4. Subtract 12 from -12, giving you -24=-8x. Then divide 24 by 8, giving you 3=x.
5. Add .03 to -9, giving you 1.3n= -8.97. Divide-8.97 by 1.3 to get n=-6.9.
6. Subtract 7/9 from 2/9 leaving you with -5/9=-5/11h. Divide and get h=1 and 2/9.
Hope this helped! : )
