Answer:
207,50
Step-by-step explanation:
1% = 2,5
2,5x25 = 62,5 250 - 62,5 = 187,5
2,5x8 = 20
187,5+20= 207,50
Solution
For this case we have the following
y+3 = x = 10
Then x= 10
So we can set up this equation:
y+3 = 10
y= 7
Then the answer is:
y=7
Answer:
a. 4 : 1
b. 2 students
c. 3 : 1
Step-by-step explanation:
a. There were 12 students who got a C and 3 students who got As. The ratio is therefore:
12 : 3
Take it to the lowest form by dividing both sides by 3:
= 4 : 1
b. There were 4 students with a D grade and 8 with a B. The ratio is:
= 4 : 8
Taken to the lowest form that would be:
= 1 : 2
This means that for every student receiving a D, 2 students received an A.
c. 12 students received a C and 4 students received a D. That ratio is therefore:
= 12 : 4
Take to the lowest form by dividing both sides by 4:
= 3 : 1
Answer:
28.3 square inches
Step-by-step explanation:
Use the area of a circle to determine its area:

Therefore, the area of a circle with a radius of 3 inches is 28.3 square inches
just multiply 45 time 31!
