Levi invests money in an account paying a simple interest of 8.7% per year. If he invests $70 and no money will be added or removed from the investment, how much will he have in one year, in dollars and cents?
Answers
Answer:
Pn=Po(1+r)^n
r=8.7%=8.7/100=0.087
Po=$70
n=1
P1=70(1+0.087)^1
=70(1.087)=76.09
=76
Answer:$76.09
Step-by-step explanation:
100%+8.7%=
108.7%\,\,108.7\%108.7%
Whole balance before interest = 100%, then add on interest
108.7% of the current balance means 108.7100 of it.\text{108.7\% of the current balance means \(\frac{108.7}{100}\) of it.}108.7% of the current balance means 100108.7 of it.
"Percent" literally means "out of 100."
108.7100=\frac{108.7}{100}=100108.7=
1.087\,\,1.0871.087
To find 108.7% of the current balance, multiply by 1.087:\text{To find 108.7\% of the current balance, multiply by \(1.087\):}To find 108.7% of the current balance, multiply by 1.087:
$70×1.087=\$70\times1.087=$70×1.087=

x³ is the right answer.I need help can you guys answer it the question is which rate describes a unit rate of 8:1???
options:
A: 12 feet for 3 dogs
B:40 miles for 5 hours
C: 70 for 5 umbrellas
D: 45 sit ups in 9 seconds
Answers
solution: simplify both numbers by the gcf
40/5=8
5/5=1
8:1
Answer: B) 40 miles for 5 hours
Divide both values by 5 and we'll simplify that to 8 miles for 1 hour. This is the same as saying 8 miles per hour, or 8 mph.
The ratio 8:1 is read as "8 to 1", meaning the first value is 8 times that of the second value. Note how 40 is 8 times that of 5, ie 40 = 8*5.

2/3x - 2 = 3/7 rewrite without fractions
Answers
The value of the expression in can be estimated by using LCM and algebraic rules and it comes 3.64.
How given expression can be rewrite or simplified?To rewrite the equation 2/3x - 2 = 3/7 without fractions, we need to eliminate the fractions by multiplying both sides of the equation by the least common multiple (LCM) of the denominators.
The denominators in this equation are 3 and 7, and their LCM is 21. So, we will multiply both sides of the equation by 21:
21 x (2/3x - 2) = 21 x (3/7)
Simplifying the left-hand side, we distribute the 21 to both terms:
14x - 42 = 9
Adding 42 to both sides, we get:
14x = 51
Finally, dividing both sides by 14, we get
x = 3.64 (rounded to two decimal places)
Therefore, the equation 2/3x - 2 = 3/7, rewritten without fractions, is 14x - 42 = 9. The solution to the equation is x = 3.64.

What is the y-intercept of this line: y= 7x-5
Answers
Answer:
- 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 7x - 5 ← is in slope- intercept form
with y- intercept c = - 5
The y-intercept of the line y = 7x - 5 is -5.
To find the y-intercept of the line represented by the equation y = 7x - 5, we need to determine the value of y when x is equal to zero. The y-intercept represents the point where the line crosses or intersects the y-axis.
In this case, when we substitute x = 0 into the equation, we get:
y = 7(0) - 5
y = -5
Therefore, the y-intercept of the line y = 7x - 5 is -5. This means that the line intersects the y-axis at the point (0, -5), with the y-coordinate being -5. Graphically, this indicates that the line crosses the y-axis at a height of -5 units.

What is the equation for the line in slope-intercept form?
Enter your answer in the box.
Answers
_________the answer is -4+5_________
To find the slope use formula: (y2-y1)/(x2-x1). We get : (13-5)/(-2-0) = 8/-2 = -4
For equation of line we know y=mx+b where m is the slope and b is the y-intercept. We know m=-4. So we have:
y = -4x+b
To find b, we just replace one of the coordinates for x and y. Let’s take (0,5)
5 = -4(0)+b
b=5
So the equation of the line is:
y = -4x+5

Answer:
x+y = 1
x = 3, y = -2
Step-by-step explanation:
Given the expressions
x-y = 5
x²-y² = 5
From 2:
x²-y² = 5
(x+y)(x-y) = 5 .... 3
Substitute equation 1 into 3;
(x+y)(5) = 5
Divide both sides by 5
x+y = 5/5
x+y = 1
b) To deduce x and y, we will solve the equation below simultaneously
x-y = 5
x+y = 1
Add both equations
x+x = 5+1
2x = 6
x = 6/2
x= 3
Substitute x = 3 into equation 1
Recall from 1:
x-y = 5
3-y = 5
y = 3-5
y = -2
Hence x = 3, y =-2
