Answer:
1394
Step-by-step explanation:
Set up equation to find the number:
Variable n = number
65/100 = 1105/n
Cross multiply:
65 × n = 100 × 1105
65n = 110,500
n = 1700
Check your work:
1700 × 65%
Convert percentage into decimal:
1700 × 0.65
1105
Correct!
Find 82% of 1700:
Variable x = 82% of 1700
82/100 = x/1700
82 × 1700 = 100 × x
139,400 = 100x
1394 = x
Check your work:
1700 × 82%
1700 × 0.82
1394
Correct!
Answer: 2 visits
Step-by-step explanation: Because you already have to pay for a $35 membership, you do 45-35=10 because the maximum amount of money you can spend is $45.
Then, you see that it is $5 per visit, therefore, letting you only be able to visit twice because 5+5=10.
135 times because 675 divided by 5 is 135. you would divide the number of her heart beats by the number
Answer:
∫
= ㏑|x| +c
Proof:
let x = 
take derivative for both sides
so dx = * du
substitute in the original function
∫du = u + C
u = ㏑|x|
Multiply by for to get t alone 9 times four is 36
