Answer:
1000 : 1000 : 1500
Step-by-step explanation:
2 + 2 + 3 = 7
3500 ÷ 7 = 500
2 × 500 = 1000
2 × 500 = 1000
3 × 500 = 1500
1000 : 1000 : 1500
Answer:
55
Step-by-step explanation:
Remark
This is a really good question to know the answer to. <PRQ = 1/2 POQ (the central angle. )
The central angle for this question is 110o. So any angle that has its vertex on the circumference is 1/2 110 = 55. The central angle and the angle on the circumference must be related as they are as this question is. (Both are on the same side of PQ which is not drawn but you can draw it).
So 2/7 cookies on Monday
n 1/3 more on Tuesday
so we are going to fine Tuesday's amount , to find what fraction did Gail sell on the two days
so
2/7 + 1/3
find lCM which is 21
u add and get 13/21
so
31/21+2/7=19/21
Answer:
Use the formula V = 4/3pi r^3
Substitute r for 7 cm
Step-by-step explanation:
-6x + 6y =6
-6x + 3y = -12
You would multiply the bottom equation by -1 to make -6x a positive so you can eliminate it.
-6x + 6y = 6
6x + -3y = 12
Eliminate -6y and add 6y to -3y as well as 6 and 12.
0 + 3y = 18
3y = 18
divide both sides by 3
y = 6
now that you know the value of y it will be easy to find x :)
