Answer:
5100 mm², hope that helps! (OwO)
Step-by-step explanation:
surface area]=2*[area of the base]+[perimeter of the base]*height
area of the base=30*70-----> 2100 mm²
perimeter of the base=2*(30+70)-----> 200 mm
height=4 1/2 mm-----> (4*2+1)/2-----> 9/2 mm
[surface area]=2*[2100]+[200]*9/2-----> 5100 mm²
Y=5 because the two triangles are congruent due to the postulate SAS
Answer:
9
Step-by-step explanation:
area of a circle = pi times radius^2
254.34= 3.14 X r^2 get rid of 3.14 by dividing both sides by 3.14
254.34/3.14= r^2
81= r^2
find the square root of 81=9
Answer:
31

thye blow up 36 balloons in total but 5 pop 36-5=31
Answer:
Step-by-step explanation:
Without a second equation relating x and y, we can solve 3x - 1/2y = 2 ONLY for x in terms of y or for y in terms of x:
x in terms of y: Multiply all three terms of 3x - 1/2y = 2 by 2, to eliminate the fraction: 6x - y = 4. Now add y to both sides to isolate 6x: 6x = 4 + y.
Last, divide both sides by 6 to isolate x:
x = (4 + y)/6
y in terms of x:
y = 6x - 4
If you want a numerical solution, please provide another equation in x and y and solve the resulting system.
