Answer:
A and E
Step-by-step explanation:
A will give the total pound.
E will give the number of servings.
The team won 4 gold medals, 4 silver medals and 10 bronze medals.
Step-by-step explanation:
Given,
Total medals won = 18
Ratio of gold, silver and bronze = 2:2:5
Let,
x be the original number.
Therefore,
Gold medals = 2x
Silver medals = 2x
Bronze medals = 5x
According to given statement;
Dividing both sides by 9
Gold medals = 2x = 2(2) = 4
Silver medals = 2x = 2(2) = 4
Bronze medals = 5x = 5(2) = 10
The team won 4 gold medals, 4 silver medals and 10 bronze medals.

Answer:
62.8yd
Step-by-step explanation:
formula for circumference of a circle = 2 π r
The perimeter is 4 semi circles, so 2 full circles. The diameter is 10yd and the radius is half the diameter, so the radius is 5yd
working:
2 x π x 5 = 31.4yd
31.4 x 2 = 62.8yd
Answer:
a=8
b=17
Step-by-step explanation:
Isoceles means we will have 2 congruent sides in this triangle.
So it appears we are to assume it is sitting on its base which means that other side has measurement ax+9 as well
So we have the sum of the 3 sides is the perimeter.
That means we have the equation:
(ax+9)+(ax+9)+(4x+b)=20x+35
Combine like terms:
(a+a+4)x+(9+9+b)=20x+35
(2a+4)x+(18+b)=20x+35
This implies 2a+4=20 and 18+b=35.
2a+4=20
Subtract 4 on both sides:
2a=16
Divide both sides by 2:
a=8
18+b=35
Subtract 18 on both sides:
b=17
So a=8 and b=17.
