Answer:
22 grams
Step-by-step explanation:
loses 50% of it's mass per 22 years
so after 22 years the mass would be 44 grams
22 years later would leave 50% of 44 grams = 22 grams
Answer:
Do l x w. Length (x) width.
Step-by-step explanation:
Answer:
2πr=72
=2*22/7*r=72
=r=72*7/44=504/44=252/22=126/11=11.45
=πr theta /180=22/7*11.45*60/180
=11.99=12(approx)
answer is (a) 12
Answer:
Metallic Balloons = 74
Bunches of Helium Balloons = 38
Step-by-step explanation:
The question basically asks for the number of "metallic balloons" sold and the number of bunches of "helium balloons" sold.
We will do it in our way. Let B be number o metallic balloons and H be number of bunches of Helium balloons.
Since Metallics cost 2 each and Heliums cost 3.5 per bunch and totaled sales is 281, we can write and equation as:
2B + 3.5H = 281
and, since they sold 36 MORE metallic than helium ,we can write an equation as:
B - 36 = H
We can put 2nd equation in 1st one and solve for B first:

B = 74
Now, we find H:
H = B - 36
H = 74 - 36 = 38
H = 38
The answer is x(x+7)=169 because the formula for a right triangle is a^2+b^2=c^2. With that said 13 squared as the hypotenuse is 169. since ether is one side that has to be 7 feet longer than the other side that means you add 7 to the unknown length, x. Then you still have to add x into the equation considering it is still aprat of the problem. HOPE THIS HELPS!!!
