What do you mean? 7 in 0.37 is 0.07 or 7 hundredths.
7 in 0.73 is 0.7 or 7 tenths?
Is that what you meant...
Step-by-step explanation:
1. a) q=4+0.8(7)
q=4+5.6
q=9.6
b) q=4+0.8(100)
q=4+80
q= 84
2. a) 12=4+0.8p
-4 -4
<u>8</u>=<u>0.8p</u>
0.8 0.8
10=p
b) 60=4+0.8p
-4 -4
<u>56</u>=<u>0.8p</u>
0.8 0.8
70=p
Answer: 2005
Step-by-step explanation:
Exponential function to determine the value of item after t years,
, where r= rate of growth, A=Initial value.
As per given , A = 7.85% = 0.0785
A = $125,000
Substitute all values in function, we get
When f(x)= 3A , then
Taking tog on both sides , we get
The year will be 1990+15= 2005
Hence, the required year = 2005
Answer:
D.
Step-by-step explanation:
There is not enough information to determine congruency. The corresponding angles are congruent, but angle measures do not affect side lengths. For example, a 45-45-90 right triangle could have side measures of 1, 1, √2 and another 45-45-90 right triangle could have side measures of 2, 2, 2√2. They are both special right triangles, but they are not congruent until you know some side lengths. You can only say these are similar.
Bruce does have enough money to buy the video game.
x/42 = 30/100
x=12.60 - This is the amount of money the video game is without tax
x/12.60 = 5/100
x=0.63 - sales tax amount
0.63+12.60=13.23 - amount of video game with tax
