Which of the following formulas shows how to calculate the ending balance of an account with a beginning balance of $600 that earns 3.5% compound interest over 8 years?
Answer:
[tex]A(t) = 600(1.035)^8[/tex]
The ending balance is of $790.1.
Step-by-step explanation:
Compound interest:
The amount of money earned after t years, in compound interest, is given by:
[tex]A(t) = A(0)(1+r)^{t}[/tex]
In which A(0) is the initial amount of money and r is the interest rate, as a decimal.
$600 that earns 3.5% compound interest over 8 years
This means, respectively, that:
[tex]A(0) = 600, r = 0.035, t = 8[/tex]
So, the formula is:
[tex]A(t) = A(0)(1+r)^{t}[/tex]
[tex]A(t) = 600(1+0.035)^{8}[/tex]
[tex]A(t) = 600(1.035)^8[/tex]
Ending balance:
The ending balance is:
[tex]A(t) = 600(1.035)^8 = 790.1[/tex]
The ending balance is of $790.1.

9514 1404 393
Answer:
D There is an infinite number of solutions to the system of equations
Step-by-step explanation:
When you put the first equation in standard form by dividing it by 2, you get ...
x -2y = 4
When you put the second equation in standard form by dividing it by 8, you get ...
x -2y = 4
These are the same equation, so describe the same line. There are an infinite number of (x, y) pairs that will satisfy this equation.
There is an infinite number of solutions.

Lauren wants to gift wrap a box which is in the shape of a cube. The dimensions of the cube is 25 cm. Determine the surface area of the box to knov
how much wrapping paper should be purchased.
Answer:
3,750cm²
Step-by-step explanation:
Total surface area of a cube is expressed as;
A = 6L²
L is the side length of the cube;
Given
L = 25cm
TSA = 6 (25)²
TSA = 6 * 625
TSA = 3,750cm²
Hence the total surface area of the box is 3,750cm²

Which angle measure must equal 52°?
A. а
в. Ь
с. с
D. d
Е. е
Answer:
Option C will be your answer
Step-by-step explanation:
Angle C will be equal to 52 by vertical angle theorem
hope it helps you
have a great day !!
Angle c is the vertical opposite angle with 52° so it will have a measure of 52° thus option (C) is correct.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
Two opposite angle made by two intersecting lines is said to be vertically opposite angle so the angle opposite to 52° is c so, ∠c = 52°.
Hence " Angle c has a measure of 52° since it is the vertical opposite angle with 52°".

9514 1404 393
Answer:
C) 625π cm^2
Step-by-step explanation:
The area of a circle is given by ...
A = πr²
where r is the radius. The radius is half the diameter, so is 25 cm. The area is ...
A = π(25 cm)² = 625π cm²

Step-by-step explanation:
cost of tank tops
20 / 5 = $4 each
cost of t-shirts
35 / 5 = $7 each
7 - 4 = $3
Answer:
$3
Step-by-step explanation:
1.Approach
To solve this problem, one must first find the cost of each product. This can be done by diving the price by the amount of each product. After finding the unit price of each product, one will subtract the cost of the tank-top from the cost of the t-shirt.
2.The unit price of a t-shirt
It is the given that 5 t-shirts cost $35. Divide the price of the shirts by the number of shirts to find the cost of each individual shirt.
35 ÷ 5 = 7
Each individual t-shirt costs $7.
3.The unit price of a tank-top
It is given that 5 tank-tops cost $20. Divide the price of the tank-tops by the number of tank-tops to fund the unit price of each tank-top.
20 ÷ 5 = 4
Each tank-top costs $4.
4.Find out how much more each shirt costs
Now subtract the price of the unit price of the tank-top from the unit price of the t-shirt.
(t-shirt) - (tank-top)
= 7 - 4
= 3

Answer:
2.1134 liters
Step-by-step explanation:
There are 4 quarts in a gallon and each quart is 1.0567 liters. 2 quarts are 1/2 a gallon. 1.0567*2=2.1134
9514 1404 393
Answer:
2. 1.8927 L
3. 603.22 cm²
Step-by-step explanation:
To convert units, multiply by a ratio whose value is 1. That is, the numerator and denominator are equal amounts, but have units that cancel ones you don't want and give you units you do want.
2.
[tex]\displaystyle \frac{1}{2}\text{ gal}\times\frac{4\text{ qt}}{1\text{ gal}}\times\frac{1\text{ L}}{1.0567\text{ qt}}=\frac{4}{2\times1.0567}\text{ L}\approx\boxed{1.8927\text{ L}}[/tex]
__
3.
[tex]A=LW=(8.5\text{ in})(11\text{ in})\times\left(\dfrac{2.54\text{ cm}}{1\text{ in}}\right)^2=\boxed{603.2246\text{ cm}^2}[/tex]
_____
Additional comment
It can be helpful to remember that a liter is larger than a quart. So 2 quarts will be less than 2 liters. (You may recall reading on the half-gallon container that it holds 1.89 L.)

5. How much force is needed to stop a 1,400 kg truck pulling up to a stop light if
the truck took 4 seconds to stop and was moving at 36 m/s?
Answer:
Step-by-step explanation:
F=ma
F=m(dv/dt)
F=1400(-36/4)
F=-12600N (the negative sign just means the force was slowing the vehicle, the magnitude of the force is just the absolute value.
F=12600N
