The answer is 25 children and 75 adults. Equation 1: A+C= 100 and equation 2: 2c+3a= 275
25(2)=50 75(3)=225.
225+50=275
Also 75+25=100
The answer is
the vector PQ has (4-1, 8-2) as components, so it is vecPQ= (3, 6)
using the definition
the distance PQ= sqrt ( 3²+6²)= sqrt(9+36)=sqrt(45)
To find the difference, subtract Thea's earnings from Hadley's earnings.
Thea earned $54 more than Hadley.
Answer:
About 588.7 mm^3
Step-by-step explanation:
The formula for the volume of a sphere is (4/3)*pi (or in this case 3.14)*r^3, where r is the radius.
We need the radius. We are given the diameter, 10.4.
The radius is half the diameter, so 10.4/2=5.2.
Use r=5.2 and put it into the formula:
(4/3)*3.14*5.2^3≈588.7
