Answer:
15
Step-by-step explanation:
In this problem we need to use the numbers given. So in the problem it states that k = 20 and v = 10. We can replace the letters in the equation for the numbers that it equals so the equation can make sense so 25 - 20 + 10 because k is 20 and v is 10 I simply just replaced the letters with the numbers given in the problem. Then we can just subtract 25 - 20 which is 5 and add 10 which leaves you at a final answer of 15. Hope this helped!
20100 = 16000 * (1.02)^ t
20100/16000 = 1.02^t
1.25625 = 1.02^t
log 1.25625 = t * log 1.02
t = log 1.25625 / log 1.02
= 11.5
Answer: 10 + 7x
40
We can use exclusion method:
A and C is not correct because Ms Hernandez doesn't want to spend more than 40 dollars --> so it must be less than or equal to 40
D. y = 10x, in 8 years she will have saved $8,000.
Since every year Cora saves $1,000. So $1,000 × 8 = $8,000.
Answer:
width= 223.9 ft
Step-by-step explanation:
perimeter=2(l+w)
948.2=2(250.2+w)
948.2=500.4+2w
948.2-500.4=2w
447.8=2w
w=447.8/2
=223.9 ft
