Answer:
$511.7
Step-by-step explanation:
Given data
Cost of stereo system= $480.50
Tax= 6 1/2% = 6.5%
Let us find the amount of the tax
=6.5/100*480.5
=0.065*480.5
=$31.2
Hence the amount of the tax = $31.2
Therefore the total cost is
=31.2+480.50
=$511.7

Rewrite –220° in radians. Write the solution as a fraction in simplest form.
Answer:
- [tex]\frac{11\pi }{9}[/tex]
Step-by-step explanation:
To convert degrees to radians
radian measure = degree measure × [tex]\frac{\pi }{180}[/tex] , then
radian measure = - 220 × [tex]\frac{\pi }{180}[/tex] ( divide 220 and 180 by 20 )
= - [tex]\frac{11\pi }{9}[/tex]
Write an explicit rule and a recursive rule for each sequence
Answer:
[tex]a_{n}[/tex] = 1.3n - 4.7
Step-by-step explanation:
There is a common difference d between consecutive terms
d = - 2.1 - (- 3.4) = - 0.8 - (- 2.1) = 0.5 - (- 0.8) = 1.8 - 0.5 = 1.3
This indicates the sequence is arithmetic with nth term ( explicit rule )
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 3.4 and d = 1.3 , then
[tex]a_{n}[/tex] = - 3.4 + 1.3(n - 1) = - 3.4 + 1.3n - 1.3 = 1.3n - 4.7
A recursive rule allows a term in the sequence to be found by adding d to the previous term, that is
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 1.3 : a₁ = - 3.4
Solve by using common denominators 2/1 divide 1/4

Which expression is equivalent to 5 ( 3x + 3 ) − 7x
A. 8x + 15
B. x +15
C. 8x+3
D. x+3
the answer is letter A bro
Answer:
The first Option is equivalent to the equation.
Step-by-step explanation:
1) Expand by distributing term.
[tex]15x + 15 - 7x[/tex]
2) Collect like terms.
[tex](15x - 7x) + 15[/tex]
3) Simplify.
[tex]8x + 15[/tex]
Hence, 8x + 15 is equivalent to this equation.
What is the solution to the equation x3 = 8 /27?
A. x = ± 2/7
B. x = ± 2 /3
C. x = 2/27
B. x = 2/ 3
Answer: x=2/3
Step-by-step explanation:
x3=8/27
(x)^3=(2*2*2)/(3*3*3)
(x)^3=(2)^3/(3)^3
(x)^3=(2/3)^3
same power got cancel
x=2/3

Answer:
30.1 ft²
Step-by-step explanation:
The area of a triangle with an included angle and two sides cam be found using the formula, A = ½*ab*sin(C)
a = 7 ft
b = 9 ft
C = 73°
Plug in the values
Area = ½*7*9*sin(73)
Area = 30.1235998 ≈ 30.1 ft² (nearest tenth)

Dad is getting food ready for my birthday party! Including me, there will be 14 people at the party. Dad is baking cupcakes for us! He can bake 16 cupcakes per batch.
How many batches should I tell Dad to make so we can each have 5 cupcakes?
Answer:
5 batches
Step-by-step explanation:
fist to find how many cupcakes you need multiply the amount of people times amount of cupcakes per person
(if rule is 5 per person)
14x5=70
then you want to find how many batches to make
70/16=4.375
but you and make 0.375 batches so just make 1 more batch
so you should tell your dad to bake 5 batches
can someone help me plz
Answer:
9442 lb
Step-by-step explanation:
First find the volume of the tank. This being a sphere, the volume is V =(4/3)π·r³. Here the diameter is 17 ft, so the radius, r, is half that: 8.5 ft.
Then the volume of the sphere is V = (4/3)π·(8.5 ft)³, and half that (the volume of the hemisphere) is (2/3)π·72.25 ft³.
Water weighs 62.4 lb/ft³. To find the weight of the water in the full tank, multiply the tank volume by this weight density 62.4 lb/ft³:
×
(2/3)π·72.25 ft³ · 62.4 lb/ft³ ≈ 9442 lb
Solve 6f-4g=1,6f-6g=5
Answer:
The solution is (-1/2, -2)
Step-by-step explanation:
Given 6f-4g=1,6f-6g=5, write these in columnar form:
6f-4g=1
6f-6g=5
Change all of the signs in the first equation:
-6f + 4g = -1
6f-6g=5
-------------------
-2g = 4, and so g = -2
Substituting -2 for g in either equation enables us to find f. Let's use the first equation: 6f - 4(-2) = 5 yields 6f + 8 = 5, or 6f = -3
Then f = -1/2 and g = -2. The solution is (-1/2, -2)
Find the value of n that makes the equation true.
n+5=n+7
Answer:
No solution
Step-by-step explanation:
Answer:
There's not a value of n so that n + 5 = n + 7
Step-by-step explanation:
if n + 5 = n + 7, then:
subtract 5 from each side of the equation:
n = n + 2 which does not have a solution for n

Jackie bought a 3-pack of tubes of glue. She used 0.27 ounce of the glue from the 3-pack
and had 1.35 ounces left in total. Which describes a way to determine the number of ounces
sold in each tube of glue?
Divide 1.35 by 3 and then subtract 0.27 from the quotient.
Solve for in the equation 3 (x - 0.27) = 1.35.
Solve for x in the equation 3x - 0.27 = 1.35.
Subtract 0.27 from 1.35 and the divide the difference by 3.
Answer:
The answer is (A)
Step-by-step explanation:
:D
Answer:
Solve for in the equation 3 (x- 0.27)= 1.35
Step-by-step explanation:
First you look at a diagram and notice that you are moving forward so you are multiplying the 3 pack of tubes by the 0.27 ounce of glue to get your answer of 1.35

Carmen had
of a spool of yarn. She used
of her yarn for a project. What fraction of the spool was used for the project?
Write your answer in simplest form.
it would depend how much you actually used, but you would take the amount you used and divide it by the total amount of yarn. so if the yarn was 4m long and you used 2m then it would be 2/4 which is 0.5 which is also 50%, so half the yarn was used.

Answer:
V = (4, 4 )
Step-by-step explanation:
Use the midpoint formula, the equation corresponding coordinates to the coordinates of the midpoint M
let V = (x, y ) , W = (8, 6 ) , then
[tex]\frac{x+8}{2}[/tex] = 6 ( multiply both sides by 2 )
x + 8 = 12 ( subtract 8 from both sides )
x = 4
and
[tex]\frac{y+6}{2}[/tex] = 5 ( multiply both sides by 2 )
y + 6 = 10 ( subtract 6 from both sides )
y = 4
coordinates of V = (4, 4 )
