Joel opened a
savings account and
deposited $3500 as
principal. The account
earns 7% interest,
compounded
semianually. What is the
balance after 48
months?
Answer:
Step-by-step explanation:
The balance of the savings account after 48 months can be calculated using the formula for compound interest:
A = P * (1 + r/n)^(nt)
where:
A is the balance after t years
P is the principal (initial amount)
r is the interest rate (as a decimal)
n is the number of times compounded per year
t is the number of years
Step-by-step, the calculation is as follows:
Convert the interest rate from a percentage to a decimal:
r = 7% = 0.07
Determine the number of times compounded per year:
n = 2 (compounded semi-annually)
Determine the number of years:
t = 48 months / 12 months/year = 4 years
Plug the values into the formula:
A = P * (1 + r/n)^(nt)
A = $3500 * (1 + 0.07/2)^(2 * 4)
Calculate the balance using the formula:
A = $3500 * (1.035)^8
A = $3500 * 1.306769
A = $4588.72
So, the balance in the savings account after 48 months is $4588.72.
Which of the following is the midsegment for A ACE?
A. AC
B. BC
C. DB
D. CE
Explanation:
Points B and D are midpoints of segments AC and CE respectively. This is because of the tickmarks indicating congruent segment pieces (AB = BC and CD = DE)
Joining the midpoints together forms a midsegment. The midsegment is half as long as the side parallel to it. This means BD is half as long as AE. Flip things around to say that AE is twice as long as BD.

What is Exponential function?The exponential function is a mathematical function denoted by f(x)=\exp or e^{x}. Unless otherwise specified, the term generally refers to the positive-valued function of a real variable, although it can be extended to the complex numbers or generalized to other mathematical objects like matrices or Lie algebras.
here, we have,
An exponential function is in the form:
y = abˣ
where y,x are variables, a is the initial value and b is the multiplicative factor.
Let y represent the amount of substance remaining after x hours. Hence:
a = 9375, at x = 4, y = 15:
15 = 9375(b)⁴
b = 0.2
y = 9375(0.2)ˣ
For the 7th hour, x = 7:
y = 9375(0.2)⁷
= 0.12
The amount of radioactive material that would remain by the 7th hour of decay is 0.12 grams.

Metalworking Twelve equally spaced holes are to be drilled in a metal strip 3414-in. long, with 2 in. remaining on each end. What is the distance, to the nearest hundredth of an inch, from center to center of two consecutive holes.
Rounded to the nearest hundredth of an inch, the distance is 310.91 inches.
How would you define distance?How far apart or how far away items or locations are from one another is measured numerically as distance. A physical quantity, it is typically stated in terms of meters, kilometers, miles, or feet. Given that it simply has magnitude and no direction, distance is a scalar quantity.
Usually, a formula is used to determine the distance between two points. One example is the distance formula in Euclidean geometry, which includes computing the square root of the sum of the squares of the coordinate differences between the two points.
Distance can be measured in a variety of contexts, including physics, where it is used to describe an object's displacement through time, and geography, where it is used to define the separation between two points on the surface of the Earth. It is also frequently used in daily life when people go for walks or runs or when they drive from one area to another to calculate the distance they travel.
There are no holes in the first and last 2 inches of the metal strip, leaving 3410 inches (3414 - 2 - 2) as the remaining length.
We can divide the total remaining length by the number of gaps between the holes to determine the distance between the centers of two adjacent holes. The distance between the 12 holes is determined by the fact that there are 11 gaps between them.
distance = (total length - length of 2 end pieces) / (number of gaps)
distance = (3410 in.) / 11
distance ≈ 310.91 in.
Rounded to the nearest hundredth of an inch, the distance is 310.91 inches.

It should be noticed that every outside angle and corresponding interior angle constitute a linear pair. We are aware that a triangle's internal angle is created when its sides come together at its apex.
Given that,
The measure of angle 4 is 120°, and the measure of angle 2 is 35°.
Triangle A B C. Angle A is 2, angle B is 1, and angle C is 3. The exterior angle to angle B is 5, and the exterior angle to angle C is 4.
The sum of an interior and exterior angle is 180°,
∠4 + ∠3 = ∠1 + ∠5 = ∠2 + ∠6 = 180°
and ∠2+ ∠1 +∠3 = 180°
Also, ∠3 = 180 - ∠4
∠3 = 180 - 120 = 60°
Substitute the values,
∠2+ ∠1 +∠3 = 180°
35 + ∠1 + 60 = 180
∠1 = 180 - 95
∠1 = 85°
Now, ∠1 + ∠5 = 180
∠5 = 180 - 85
∠5 = 95°
Hence, the measure of angle that is an exterior angle to B is 95°.

Tamaya borrowed $8,500 to buy a car. After 42 months, she ended up paying $1,785 in interest on the car loan. What was the simple interest rate on Tamaya’s car loan?
Answer:
5%
Step-by-step explanation:
We can use the formula for simple interest to solve for the interest rate:
I = Prt
where:
I is the interest
P is the principal (the amount borrowed)
r is the interest rate
t is the time in years
We know the principal (P) is $8,500, the interest (I) is $1,785, and the time (t) is 42 months, or 42/12 = 3.5 years. So, we can plug in the values and solve for r:
I = Prt
$1,785 = $8,500 * r * 3.5
$1,785 / $8,500 / 3.5 = r
r = 0.05, or 5%
So, the simple interest rate on Tamaya's car loan was 5%.
A washer and a dryer cost $993 combined. The washer costs $43 more than the dryer. What is the cost of the dryer?
Answer:425
Step-by-step explanation:
993-43=950
950/2=425
Answer:
$475
Step-by-step explanation:
Let's call the cost of the dryer x. That means the cost of the washer is x + $43. The combined cost of the two is $993, so we can write the equation:
x + (x + $43) = $993
Expanding the right side:
2x + $43 = $993
Subtracting $43 from both sides:
2x = $950
Dividing both sides by 2:
x = $475
So the cost of the dryer is $475.

What is the slope of the line that passes through the points ( 6 , 7 ) (6,7) and ( 16 , 22 ) (16,22)? write your answer in simplest form.
Answer:
Step-by-step explanation:
The slope of a line is the change in y (the vertical axis) divided by the change in x (the horizontal axis).
Given the two points (6,7) and (16,22), we can calculate the slope as follows:
Change in y = 22 - 7 = 15
Change in x = 16 - 6 = 10
Therefore, the slope of the line passing through the two points is:
slope = change in y / change in x = 15 / 10 = 3/2
So the slope of the line is in its simplest form, 3/2.
