The perimeter of a rectangle is 162 inches. what are the dimensions of the rectangle if the length is 7 times than 3 times the width?
Answers
Answer:
3.68 inches × 77.28 inches
Step-by-step explanation:
Given that,
The perimeter of a rectangle is 162 inches.
Let the width is b.
ATQ,
Length = 7 times than 3 times the width
l = 7(3b) = 21b ...(1)
The perimeter of a rectangle is given by :
P = 2(l+b)
Put all the values,
162 = 2(21b+b)
81 = 22b
b = 3.68 inches
Put the value of b in equation (1)
l = 21b
= 21 (3.68)
= 77.28 inches
Hence, the dimensions of the rectangle are 3.68 inches × 77.28 inches

Matthew purchased a desk that was on sale for 45% off the orginal price of $480.If the sales tax was 8% (of the sale price), how much did mattew spend on the desk
Answers
Answer:
285.12
Step-by-step explanation:
discount amount = 45/100 x 480= 45x48/10
=216.0
price after discount= 480-216=264
sales tax= 8/100 x 264=21.12
total money spent = 264+21.12=285.12
45% of 480
= 45/100 x 480
= 0.45x480
=216
=480-216
=264
8% of 264
= 8/100 x 264
= 0.08 x 264
= 21.12
= 264 + 21.12
=285.12
Therefore, he paid $285 and 12 cents

You deposit $300 in a savings account that pays 6% interest compounded semiannually. How much will you have at the middle of the first year? How much at the end of one year?
Answers
Answer:
The total amount accrued, principal plus interest, from compound interest on an original principal of $ 300.00 at a rate of 6% per year compounded 2 times per year over 0.5 years is $ 309.00. The total amount accrued, principal plus interest, from compound interest on an original principal of $ 300.00 at a rate of 6% per year compounded 2 times per year over 1 year is $ 318.27.Step-by-step explanation:
a) How much will you have at the middle of the first year?
Using the formula
[tex]A\:=\:P\left(1+\frac{r}{n}\right)^{nt}[/tex]
where
Principle = PAnnual rate = rCompound = nTime = (t in years) A = Total amountGiven:
Principle P = $300
Annual rate r = 6% = 0.06 per year
Compound n = Semi-Annually = 2
Time (t in years) = 0.5 years
To determine:
Total amount = A = ?
Using the formula
[tex]A\:=\:P\left(1+\frac{r}{n}\right)^{nt}[/tex]
substituting the values
[tex]A=300\left(1+\frac{0.06}{2}\right)^{\left(2\right)\left(0.5\right)}[/tex]
[tex]A=300\cdot \frac{2.06}{2}[/tex]
[tex]A=\frac{618}{2}[/tex]
[tex]A=309[/tex] $
Therefore, the total amount accrued, principal plus interest, from compound interest on an original principal of $ 300.00 at a rate of 6% per year compounded 2 times per year over 0.5 years is $ 309.00.
Part b) How much at the end of one year?
Using the formula
[tex]A\:=\:P\left(1+\frac{r}{n}\right)^{nt}[/tex]
where
Principle = PAnnual rate = rCompound = nTime = (t in years) A = Total amountGiven:
Principle P = $300
Annual rate r = 6% = 0.06 per year
Compound n = Semi-Annually = 2
Time (t in years) = 1 years
To determine:
Total amount = A = ?
so using the formula
[tex]A\:=\:P\left(1+\frac{r}{n}\right)^{nt}[/tex]
so substituting the values
[tex]A\:=\:300\left(1+\frac{0.06}{2}\right)^{\left(2\right)\left(1\right)}[/tex]
[tex]A=300\cdot \frac{2.06^2}{2^2}[/tex]
[tex]A=318.27[/tex] $
Therefore, the total amount accrued, principal plus interest, from compound interest on an original principal of $ 300.00 at a rate of 6% per year compounded 2 times per year over 1 year is $ 318.27.

Answer:

Step-by-step explanation:
just trust
The formula that gives the x-coordinates of the maximum values of
y = cos(x) is kπ for k= 0, 2±, ±4.
Option B is the correct answer.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
The formula that gives the x-coordinates of the maximum values for
y = cos(x) is kπ + π/2 or (2k+1)π/2, where k is any integer.
Now,
This formula corresponds to kπ for k= 0, 2±, ±4
where k can take the values 0, 2, -2, 4, -4, etc.
The cosine function oscillates between -1 and 1, with a period of 2π.
The maximum value of the function is 1, which occurs when the argument of the cosine function is an odd multiple of π/2.
This means that the x-coordinates of the maximum values are given by:
x = kπ + π/2, where k is any odd integer
We can simplify this formula by writing k = 2m+1, where m is any integer, to obtain:
x = (2m+1)π/2
This formula covers all the possible values of k, including positive and negative integers.
For example, when m = 0, we get x = π/2, which is the first maximum value of the function.
When m = 1, we get x = 3π/2, which is the second maximum value, and so on. If we allow m to be negative, we get the values of x for the maximum values of the cosine function in the negative direction.
Therefore,
kπ for k= 0, 2±, ±4
which gives the values of k that correspond to the x-coordinates of the maximum values of y = cos(x).

In addition to his weekly salary, Ethan is paid $16 per delivery.
Last week, he made 5 deliveries, and his total pay was $215. Write a linear equation in
slope-intercept form to find Ethan's total weekly pay T if he makes d deliveries. (please help quickly! I WILL MARK BRAINLEST!!)
Answers
Answer:
Step-by-step explanation:
T=16d=135
The linear equation in slope-intercept form to find Ethan's total weekly pay is T = 16d + 135
A linear equation is in the form:
y = mx + b
where m is the slope of the line, b is the y intercept and y, x are variables.
Let T represent the total money paid to Ethan in a week for d deliveries.
Ethan is paid $16 per delivery, hence m = 16.
T = 16d + b
For 5 deliveries, his total pay was $215. Hence when d = 5, T = 215:
215 = 16(5) + b
215 = 80 + b
b = 135
T = 16d + 135
The linear equation in slope-intercept form to find Ethan's total weekly pay is T = 16d + 135
