Answer: 22 blue balloons
Step-by-step explanation:
IF 3/10 balloons are red out of 60, we have
= 18 red balloons in total
1/3 of the balloons are yellow, 60/3=20 yellow balloons
Blue balloons= 60-18 (red)-20(yellow)=22
Answer:
here ya go :)
Step-by-step explanation:
Z + Y = a right angle so need to equal 90 degrees:
Find Z & Y:
2b + 6 + 3b -1 = 90
5b +5 = 90
5b = 85
b = 85/5
b = 17
Z = 2(17) +6 = 34+6 = 40 degrees
Y = 3(17) - 1 = 51 - 1 = 50 degrees
Y & W make a straight line so need to equal 180:
W = 180 - 50 = 130 degrees.
Z & X make a straight line so need to equal 180:
X = 180 - 40 = 140 degree.

Answer:
The area of the new square=324 in²
Step-by-step explanation:
The area of a square can be expressed as;
A=L×L
where;
A=area of the square
And since the sides of a square are equal, they can be expressed as;
L=length of one side
L=length of the other side
In our case;
L=unknown
A=81 in²
replacing;
81=L²
√L²=√81
L=9
Multiply side length by 2
9×2=18 inches
The new area can be expressed as;
A=18²=324 in²
The area of the new square=324 in²
