Ernesto has $70 in a savings account. The interest rate is 5%, compounded annually. To the nearest cent, how much will he have in 3 years?
Answer: $81.03
Step-by-step explanation:
The interest is compounded annually which means that the future value formula applies:
Future value = Amount * ( 1 + rate) ^ number of years
Amount = $70
Rate = 5%
Number of years = 3 years
In 3 years, Ernesto will have:
= 70 * ( 1 + 5%)³
= $81.03
You answer 0.8 questions correctly.
a. What percent of the questions did you answer correctly?
you answer 0.8 questions correctly. what percent of the questions did you answer correctly. What fraction of the questions did you answer incorrectly? Use / for fraction and answer
Answer:
Step-by-step explanation:
Fraction:
0.8 = 8/10 = 4/5
Percent:
0.8*100 = 80%
Answer:
Solution :-0.8 can be written as
8/10 and
Percentage = 8/10 × 100
Percentage = 8 × 10
Percentage = 80%
Or,
Simply
Percentage = 0.8 × 100
Percentage = 80%

solve the inequality -2(y+4)>16
y < -12
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
−2y − 8 > 16
Step 2: Add 8 to both sides.
−2y − 8 + 8 > 16 + 8
−2y > 24
Step 3: Divide both sides by -2.
−2y/−2 > 24/−2
y < −12
Answer:
y < −12
Step-by-step explanation:
−2(y + 4) > 16
↓
−2y − 8 > 16
↓
y < −12

c. $425.26
d. $375.26
Answer:
its a. 475.26
Step-by-step explanation:
445/ 100= 4.45
4.45×3.4=15.13
15.13+445=460.13
460.13+15.13= 475.26

please help meee and show all steps please!!!ty
Answer:
x = -4 and x = 5
Step-by-step explanation:
Since [tex]x^2 + 2x[/tex] and [tex]3x + 20[/tex] both equal to y, we know that the expressions equal to each other. We can write a new equation base on that.
[tex]x^2 + 2x = 3x + 20[/tex]
Now we solve the equation.
[tex]x^2 + 2x = 3x + 20[/tex]
[tex]x^2 - x = 20[/tex]
[tex]x^2 - x - 20 = 0[/tex]
[tex](x + 4) (x - 5) = 0[/tex]
[tex]x + 4 = 0 ; x -5 = 0[/tex]
[tex]x = -4 ; x = 5[/tex]
evaluate 2x + 5 - 10 when x = 12

Ben says he will sell Catalina a ring that he found in his yard. Ben and Catalina look at the ring and decide that they are not sure what it is, probably just a shiny stone. Catalina pays Ben $10 for the ring. The ring turns out to be a diamond worth much more than $10. Ben wants the ring back, and Catalina refuses. What is the most likely result
Answer:
If both parties are over the age of 18, a lawsuit is likely to occur.
Step-by-step explanation:
Ben would likely try and sue Catalina for theft, however she wouldn't be found guilty because of the transfer of property, goods, and or services was entirely legal in this case.
What is the solution to the system of equations below? Please show work.
Y = 3/4x - 3
3x - 4y = 12
1) (4,0)
2) (0,-3)
3) no solution
4) infinite solution
Answer:
2) (0,-3)
Step-by-step explanation:
hello :
put x=0 and y= -3 in this system !
Y = 3/4x - 3
3x - 4y = 12
- 3 = 3/4(0) - 3 means : -3 = -3 ......true
3(0) - 4(-3) = 12 means : 12= 12 ......true
Evaluate function expression.
who can help ?
Given:
The graph of two function f(x) and g(x).
The expression is:
[tex]-1\cdot f(-8)-4\cdot g(4)[/tex]
To find:
The value of the given expression.
Solution:
From the given graph, it is clear that
[tex]f(-8)=-5[/tex]
[tex]g(4)=3[/tex]
Substitution [tex]f(-8)=-5[/tex] and [tex]g(4)=3[/tex] in the given expression, we get
[tex]-1\cdot (-5)-4\cdot 3[/tex]
[tex]=5-12[/tex]
[tex]=-7[/tex]
Therefore, the value of the given expression is -7.

Answer:
1) 23^a+b
2) 5^5
3) 11^x-y
4) 2^10
Step-by-step explanation:
if they have the same base numbers then they are pretty easy to combine. multiplication means you add the exponents, and division means you subtract the exponents. for number 2, you would make them the same base by making 25 -> 5^2 and then just add the exponents.
