Artur has the highest score when I added and then caleb then joshua then trio had the lowest score wait until someone else answers this time please!!!
Answer:
5. f(x) = 10,000 (1.5)^x
Step-by-step explanation:
We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.
Let's test it.
Initial:
10,000
After 1 year
10,000 + (.5*10000)
10,000 + 5000 = 15,000
After 2 years
15,000 + (.5*15000)
15,000 + 7500 = 22,500
Let's try our equation.
f(x) = 10,000 (1.5)^x
x = 2
10,000(1.5)^2
10,000(2.25) = 22,500
The same!
TanB = AC/ BC
tanB = 8 / 6
answer
tanB = <span>8/6</span>
Answer:
90
Step-by-step explanation:
The mean is measured as
mean = 
After 5 tests the mean is 84, that is
= 84 ( multiply both sides by 5 )
score = 420
let the sixth test score be x, then
= 85 ( multiply both sides by 6 )
420 + x = 510 ( subtract 420 from both sides )
x = 90
Require to score 90 on the sixth test
1. SET UP EQUATION
(15x+1)+(6x+5)+(4x-1)=180
2. SIMPLIFY
25x+5=180
3. SUBTRACT 5 ON BOTH SIDES
25x=175
4. DIVIDE 25 ON BOTH SIDES
x=7
5. PLUG IN 7 FOR EACH ANGLE
15(7)+1
6(7)+5
4(7)-1
6. SIMPLIFY
105+1
42+5
28-1
7. SOLVE
106
47
27
ANSWERS:
x=7
15x+1=106 degrees
6x+5=47 degrees
4x-1=27 degrees
