Ira invests $4000 into an account that earns 0.6% simple interest annually. Which statement best describes the relationship between the number of years Ira has his money invested and the balance in any year
The Amount of money that she received at the end of the read is $4024, the relationship between the number of years Ira has his money invested and the balance in any year differs by $24 which is the simple interest.
Amount invested by Ira = P = $4000
The rate of Interest (r) = 0.6 %
Time period (t) = 1 year.
The simple interest is given by,
[tex]S.I. = \frac{P*r*t}{100}[/tex]
Now, putting the values in the formula, we get:
[tex]S.I. = \frac{4000*0.6*1}{100} =24[/tex]
Hence, the simple interest will be $24
Now, the Amount/balance that she received in the year is A = P +S.I
A = P+S.I.
A = 4000 +24 = $4024

The equation y=2x represents a proportional relationship.
Select the true statement.
The graph is a curve
The y-intercept is 2
The slope is 2
The slope is 0
The slope of the line is 2 whose equation is given by y = 2x.
The given equation is y = 2x
The general equation of the line is given by
y = mx +c where m is the slope and c is the intercept of the line.
The slope of line a line's steepness can be determined by looking at its slope. The slope is calculated mathematically as "rise over run."
The intercept of the line is a point on the y-axis known as an intercept is where the line's slope passes.
On Comparing the given equation with the general equation, we have:
m = slope = 2

The sales revenue necessary to generate net income of $100,000 is: $416,667.
How to find the sales revenue?Using this formula to find the sales revenue
Sales revenue = Sales revenue + (Sales revenue × Net income / Fixed costs)
Let plug in the formula
Sales revenue = $250,000 + ($250,000 × $100,000 /$150,000)
Sales revenue = $250,000 + ($250,000 ×0.6666666)
Sales revenue = $250,000 + $166,666.65

What is the slope of a line perpendicular to the line whose equation is 5x-y=-7. Fully simplify your answer.
Answer:
-1/5
Step-b-1/5y-step explanation:
The rule for a perpendicular slope of a line is -1/s
In this case, we find the slope of the line first.
5x - y = -7
-y = -5x - 7
y = 5x + 7
The slope is 5, so -1/(5) is the slope of the perpendicular line.

Can you help me please and explain I don’t get this. *slope*
Answer:-5/1
Step-by-step explanation:
down 5 and over 1
to get the slope, find a spot on the graph and then go 1 to the right and read how much the graph went up or down.
on 5) you see it did neither, so m=0
when the graph goes up, m is positive, when it goes down, m is negative.
so on graph 1, you have 2 dots.
you go 2 right, and 4 down. when the dots are not 1 apart (counting going right) then divide by the steps you went right.
4 divided by 2 is 2.
-> graph went down, slope for 1) is m = -2
graph 2) you go 2 right and 2 up, 2/2 = 1. you went up, so m is positive and m = 1 for this graph.
3) is undefined because it doesn't go anywhere when you go right, it's 100% vertical
4) m = -5 because you went 1 right and 5 down
5) you go 6 right between the dots and 4 down. m is negative because it went down, not up. so m = -(4/6)

A 35-tooth gear on a motor shaft drives a larger gear having 63 teeth. If the motor shaft rotated at 900 rpm, what is the speed of the larger gear
If the motor shaft rotated at 900 rpm, the speed of the larger gear will be 100 rpm.
What is the ratio?
It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
it is given that, A 35-tooth gear on a motor shaft drives a larger gear having 63 teeth and the motor shaft rotated at 900 rpm.
The number of teeth on the smaller gear,n₂ = 35
The number of teeth on the larger gear,n₁ = 63
The gear ratio is obtained as,
n₁/n₂=63/35
n₁/n₂=9:5
If the motor shaft rotated at 900 rpm, The speed of the larger gear is,
=900 rpm / 9
=100 rpm
Thus, if the motor shaft rotated at 900 rpm, the speed of the larger gear will be 100 rpm.

Solve each equation below. Show each step and check your work.
a) 56a – 178 = 98 – 248
b) 640 + 70 = 69y + 20
Answer:
A) 0.5
B) 10
Step-by-step explanation:
A) First, you need to Combine Like Terms on the right side of the =
98-248 = -150
Now, you need to Isolate the variable by getting rid of the -178. What you do to one side, you must do the the other.
56a-178(+178) = -150(+178)
56a = 28
Finally, you must remove that 56 on the a. Since it stands for 56 x a, you must do the same you did with the -178 except with Division.
56a/56 = 28/56
a = 0.5
B) Combine Like terms
640+70 = 710
Isolate the variable
710(-20) = 69y+20(=20)
690 = 69y
Remove the 69 with division
690/69 = 69y/69
10 = y
The simple interest on a sum of money invested 6 months at 5% per annum is $1680. Determine the amount of money invested.
Answer:
9514 1404 393
Answer:
$67,200
Step-by-step explanation:
The amount if interest is given by the formula ...
I = Prt
where P is the amount invested, r is the annual rate, and t is the number of years. Here, we want to find P when r = 0.05 and t = 1/2 such that I = 1680.
P = I/(rt) = $1680/(0.05·0.5) = $1680/0.025
P = $67,200
The amount invested was $67,200.
