You have one coupon for x dollars off and another coupon for x% off.
Write a rule that helps you decide when you should use one instead the other.
Answer:
if you want an item that is 100 dollars of then you would like the precent of because 1-100 percent is 1-100 so the larger the number the more you would want the percent but if it is 10% or 5 dollars of on an item of 10 dollars then the dollars of would be better so the higher the number the more you want percentage.
Find the 70th term of the arithmetic sequence 11,19,27
Answer:
should be 563
Step-by-step explanation:
11,19,27,35, 43, 51, 59, 67, 75, 83,
91, 99, 107, 115, 123, 131, 139, 147, 155, 163,
171, 179, 187, 195, 203, 211, 219, 227, 235, 243
(there is a notable difference of 80 on each row)
243+(80x4)=243+320=563
Answer:
563
Step-by-step explanation:
This is an arithmetic sequence since there is a common difference between each term. In this case, adding to the previous term in the sequence gives the next term. In other words, .
Formula;
L = a + (n - 1)*d
Givens
n = 70
a = 11
d = 8
Solution;
t = 11 + (70 - 1)*8
t = 11 + 69*8
t = 11+ 552
t = 563

How long does the banner measure in inches and in yards?
Enter your answers in the boxes.
Answer:
64.8 inches, 1.8 feet
Step-by-step explanation:
5.4*12=64.8
5.4/3=1.8
Answer:
Inches: 64.8, Yards: 1.8
Step-by-step explanation:
To get inches you multiply 5.4 by 12 and you get 64.8. To get yards you divide 5.4 by 3 and you get 1.8.
What is an equation of the line that passes through the point (8,2) and is parallel to the line x+4y=28
Answer:
[tex]y =\frac{-1}{4}x + 4[/tex]
Step-by-step explanation:
Parallel lines have same slope
x + 4y = 28
4y = -x + 28
[tex]y=\frac{-1}{4}x+\frac{28}{4}\\\\y=\frac{-1}{4}x+7[/tex]
m = (-1/4) and line passes through (8 , 2)
Equation: y - y₁ = m(x - x₁)
[tex]y - 2 = \frac{-1}{4}(x - 8)\\\\y -2 = \frac{-1}{4}x - 8*\frac{-1}{4}\\\\y -2 = \frac{-1}{4}x + 2\\\\ y = \frac{-1}{4}x + 2 +2\\\\ y =\frac{-1}{4}x + 4[/tex]
The revenue, Y, received for selling, t, DVD players is given by the equation: Y = -1/1000 t^2 + 10t. Find the number of DVD players that must be sold to obtain the maximum revenue.
The equation Y = -1/1000 t^2 + 10t is an illustration of a quadratic function
The number of DVD players that must be sold to obtain the maximum revenue is 5000
How to determine the number of DVDs?The equation of the function is given as:
[tex]Y = -\frac 1{1000} t^2 + 10t[/tex]
Differentiate the function
[tex]Y' = -2 * \frac 1{1000} t + 10[/tex]
Set to 0
[tex]-2 * \frac 1{1000} t + 10 = 0[/tex]
Simplify
[tex]- \frac 1{500} t + 10 = 0[/tex]
Subtract 10 from both sides
[tex]- \frac 1{500} t = -10[/tex]
Multiply both sides by -500
[tex]t = 5000[/tex]
Hence, the number of DVD players that must be sold to obtain the maximum revenue is 5000

A cabinet is the shape of a triangular prism. The triangular base has a base length of 14 inches and a base height of 22 inches. The cabinet is 67.5 inches tall. What is the volume of the cabinet?
Answer:
As Per Provided Information
We have been asked to determine the volume of triangular Prism . Volume of Triangular Prism is calculated by using the following formula
[tex] \bf \: Volume_{(Triangular~Prism)} = \cfrac{1}{2} \times b \: \times h \times l [/tex]
Substitute the given value and let's calculate the volume of cabinet .
[tex] \sf \: \longrightarrow Volume_{(Triangular~Prism)} \: = \cfrac{1}{2} \times 14 \times 22 \times 67.5 \: \: \\ \\ \sf \: \longrightarrow Volume_{(Triangular~Prism)} \: = \frac{1}{ \cancel2} \times \cancel14 \times 22 \times 67.5 \: \: \\ \\ \\ \sf \: \longrightarrow Volume_{(Triangular~Prism)} \: = 7 \times 22 \times 67.5 \: \: \\ \\ \\ \sf \: \longrightarrow Volume_{(Triangular~Prism)} \: = \: 154 \times 67.5 \: \: \\ \\ \\ \sf \: \longrightarrow Volume_{(Triangular~Prism)} \: = 10395 {cm}^{3} [/tex]
Therefore,
Volume of the Triangular Prism Cabinet is 10395 cm³.A. Antonia has a green rope and a blue rope. Her green rope is 4 feet in length. She cut the green rope into 2 pieces. One of the pieces is 21 inches in length.
How many inches long is the other piece of the green rope? Use words and numbers to explain your reasoning.
B. Antonia's blue rope measures 2 yards. She wants to cut the rope into MORE than 3 pieces so all the pieces of rope are equal in length with no rope left over.
What is ONE possible way that Antonia can cut the rope so that each piece of rope is less than 24 inches in length? Use words and numbers to explain your reasoning.
Type your answer in the box below. Make sure to label each part with A and B.
Answer:
The other part is 27 in. long
Step-by-step explanation:
1 ft is 12 in
2 ft are 24 in
4 ft are 48 in
48 in - 21 in = 27 in
Answer:
Part A
Green rope = 4 ft
As 1 ft = 12 in
Then 4 ft = 4 × 12 in = 48 in
Antonia cuts the green rope into 2 pieces. One of the pieces is 21 in long. To find the length of the unknown piece, subtract the length of the known piece from the total length:
length of unknown piece = 48 - 21
= 27 in
Part B
Blue rope = 2 yd
1 yd = 36 in
Therefore, 2 yd = 2 × 36 = 72 in
Antonia wants to cut the rope into MORE than 3 pieces, and all the pieces need to be of equal length. As the length of the rope is an even number of inches, Antonia could first cut the rope in half, so she would have 2 pieces each of 36 in in length. Then she could cut both of those lengths in half, so she would have 4 pieces each of 18 in in length.

Answer:
B is the answer
Step-by-step explanation:
looking at line CF,
it is a straight line thus being 180°
the < EOD is 90° < EOF is 55°
let < COD = t
therefore,
EOD + EOF + COD = 180
90 + 55 + t = 180
taking terms
t = 180 - (90 + 55)
t = 180 - 145
t = 35
COD = 35
EOD = 90
THUS, COE = COD + EOD
COE = 35 + 90
COE. = 125

Ms. Caswell deposits $450 into an account earning 8% simple interest per year. How
much simple interest is earned after 4 years?
Answer:
$144
Step-by-step explanation:
Use the simple interest formula, I = prt, where I is the interest money created, p is the starting amount, r is the interest rate as a decimal, and t is the amount of time.
Plug in the original amount, interest amount, and amount of time:
I = prt
I = 450(0.08)(4)
I = 144
So, $144 in simple interest is made in 4 years

lets use the point (6, 8)
substitute:
8 = 2/3(6) + 4 ?
8 = 4 +4?
8 = 8
