Answer: Remaining balance is $150
Step-by-step explanation:
Contact lens= $200
25% of the amount was paid
= 25/100 × 200 = $50
Out of $200 of contact lens, $50 was paid as deposit, subtract $200 from $50 to give balance.
$200 - $50 = $150
I hope this helps.
After calculating a 25% deposit on the $200 contact lenses, which is $50, the remaining balance that needs to be paid is $150.
Explanation:If the cost of your new contact lenses is $200, and you left a 25% deposit upon ordering the lenses, we need to first calculate the amount of the deposit and then determine the remaining balance.
To find the deposit amount, we take 25% of the total cost:
Deposit = 25% of $200Deposit = 0.25 × $200Deposit = $50Once we have calculated the deposit amount, we subtract it from the total cost to find the remaining balance owed:
Remaining Balance = Total Cost - DepositRemaining Balance = $200 - $50Remaining Balance = $150So, after leaving a 25% deposit on the contact lenses, your remaining balance would be $150.

Determine the center and radius of the following circle equation:
22 + y2 – 10x + 18y + 42 = 0
Answer:
C(5,-9) and r=8.
Step-by-step explanation:
C(p, q) - center
r=radius
k:x^2 +y^2 +dx+ey+f=0
x^2+y^2 - 10x+18y+42=0
d=-10, e=18, f=42
p=-d/2=-(-10)/2=10/2=5
q=-e/2=-18/2=-9
r^2 =p^2+q^2-f
r^2 =5^2 +(-9)^2 - 42
r^2=25+81-42
r^2 =106-42
r^2 =64
r=sqrt(64)
r=8
C(p,q)=C(5,-9) r=8

Which of the following defines liquid measure?
A. The measure of how much space is filled by an object
B. Units used to measure the volume of liquids, such as water, gasoline, and
milk
C. The volume of space inside a container
D. How heavy an object is
Liquid measure refers to the units used for measuring the volume of liquids such as liters, milliliters, etc. It's closely tied to the concept of volume, which is the amount of space that an object, liquid or solid, occupies.
Explanation:Liquid measure is defined as B. Units used to measure the volume of liquids, such as water, gasoline, and milk. This concept is related to the broader idea of volume, which is the measure of the amount of space occupied by an object, regardless of its state of matter. Let's say we want to measure the volume of water we're pouring into a jug. The volume units we would use (liters, milliliters, etc.) are examples of a liquid measure. Similarly, if we are filling a car's gas tank, the liters or gallons dispensed would be a liquid measure too.
Another example is milk that is sold in containers of varying volumes, from small cartons to large gallons. Each of these volumes is a measure of liquid. So, when we talk of liquid measure, we're looking at how much space a certain quantity of liquid occupies which is generally determined in liters, milliliters or sometimes cubic meter (m³).

Which three length cannot be the length of the sides of a triangle
The missing choices are here
A. 23 m, 17 m, 14 m
B. 11 m, 11 m, 12 m
C. 5 m, 7 m, 8 m
D. 21 m, 6 m, 10 m
Answer:
21 m, 6 m, 10 m cannot be the length of the sides of a triangle ⇒ D
Step-by-step explanation:
There is a fact to form a triangle:
The sum of the lengths of the two smaller sides must be greater than the length of the third side
A.
∵ The smallest sides are 14 m and 17 m
∵ Their sum = 14 + 17 = 31 m
∵ The third side is 23 m
∵ 31 > 23
∴ 23 m, 17 m, 14 m can be the length of the sides of a triangle
B.
∵ The smallest sides are 11 m and 11 m
∵ Their sum = 11 + 11 = 22 m
∵ The third side is 12 m
∵ 22 > 12
∴ 11 m, 11 m, 12 m can be the length of the sides of a triangle
C.
∵ The smallest sides are 5 m and 7 m
∵ Their sum = 5 + 7 = 12 m
∵ The third side is 8 m
∵ 12 > 8
∴ 5 m, 7 m, 8 m can be the length of the sides of a triangle
D.
∵ The smallest sides are 6 m and 10 m
∵ Their sum = 6 + 10 = 16 m
∵ The third side is 21 m
∵ 16 < 21
∴ 21 m, 6 m, 10 m cannot be the length of the sides of a triangle

You need to use the following formula to find the volume of a Square pyramid:
[tex]V=\frac{1}{3}s^2h[/tex]
Where "s" is the edge of a side of the square base and "h" is the height of the pyramid.
Knowing that:
[tex]s_A=12\ in\\\\h_A=8\ in\\\\\\s_B=36\ in\\\\h_B=24\ in[/tex]
You can find the volume of the Pyramid A and the volume of the Pyramid B:
[tex]V_A=\frac{1}{3}(12\ in)^2(8\ in)\\\\V_A=384\ in^3\\\\\\V_B=\frac{1}{3}(36\ in)^2(24\ in)\\\\V_B=10,368\ in^3[/tex]
Finally divide the volume of the Pyramid B and the volume of the Pyramid A, in order to find how many times bigger than the Pyramid A is the Pyramid B.
You get:
[tex]\frac{10,368\ in^3}{384\ in^3}=27[/tex]

Rope costs $0.65 per foot.How much do 10.8 feet of rope cost?
Answer:
$7.02
Step-by-step explanation:
So we know that one foot of rope costs $0.65, and we are trying to fin the cost of 10.8 feet of rope. To find the cost of 10.8 feet of rope, we would multiply the length of the rope (in feet) and multiply it by the cost of one foot of rope. The length of the rope is already given to us in feet, so now we just need to multiply it by the cost per foot ($0.65).
$0.65 × 10.8 = ($0.65 × 10) + ($0.65 × 0.8) = $6.5 + $0.52 = $7.02
The cost of 10.8 feet of rope would be $7.02.
I hope this helps. :)
The required, 10.8 feet of rope costs $7.02.

Suppose that $2000 is invested at a rate of 5.1%, compounded semiannually. Assuming that no withdrawals are made, find the total amount after 6 years.
Do not round any intermediate computations, and round your answer to the nearest cent.
Solution:
The formula for compound interest, including principal sum, is:
[tex]A = p( 1 + \frac{r}{n})^{nt}[/tex]
Where,
A = the future value of the investment/loan
P = the principal investment amount
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per unit t
t = the time the money is invested
From given,
p = 2000
[tex]r = 5.1 \% = \frac{5.1}{100} = 0.051[/tex]
t = 6 years
n = 2 ( compounded semiannually)
Substituting the values we get,
[tex]A = 2000( 1 + \frac{0.051}{2})^{ 2 \times 6}\\\\A = 2000( 1 + 0.0255)^{12}\\\\\A = 2000(1.0255)^{12}\\\\A = 2000 \times 1.35278\\\\A = 2705.5649[/tex]
Thus the total amount after 6 years is $ 2705.5649
Final answer:
Using the compound interest with an initial investment of $2000 at a 5.1% interest rate compounded semiannually, the total amount after 6 years is calculated to be $2710.34.
Explanation:
To calculate the total amount after 6 years when $2000 is invested at a rate of 5.1% compounded semiannually, we use the formula for compound interest, which is [tex]A = P(1 + r/n)^(nt).[/tex] Here, A represents the future value of the investment, P is the principal amount, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the time the money is invested for in years.
We can plug the values into the formula:
P = $2000 (the initial investment)
r = 0.051 (5.1% interest rate expressed as a decimal)
n = 2 (since the interest is compounded semiannually)
t = 6 (the investment period in years)
Therefore, we calculate A using the following expression:
[tex]A = 2000(1 + 0.051/2)^(2*6)[/tex]
[tex]A = 2000(1 + 0.0255)^(12)[/tex]
[tex]A = 2000(1.0255)^12[/tex]
After calculating the above expression without rounding intermediate computations and rounding the final answer to the nearest cent, the total amount comes out to be:
A = $2710.34
Thus, the total amount after 6 years, with a 5.1% interest rate compounded semiannually, is $2710.34.
