Answer:
[tex]a_n_+_1 = a_n + 6[/tex]
Step-by-step explanation:
Recursive equations use the previous term as a base for the next. Because of this, the left side of the equation needs to be a representation of the next term. The right side of the equation consists of the current term plus, minus, times, or divided by a certain number. Therefore, your answer here is [tex]a_n_+_1 = a_n + 6[/tex].

Sally can paint a room in 9 hours while it takes Steve 5 hours to paint the same room. How long would it take them to paint the room if they worked together?
Answer: About 3 hours and 5 minutes to paint the room together.
Step-by-step explanation:
Sally can paint 1/5 of the room in an hour and Steve can paint 1/8 of the room in an hour.
Room/Hour
1/5 ± 1/8 =8/40
8/40+5/40=13/40
How long to paint the room?
13/40 x 1= 40/13
40÷13=3.0777
So the answer will be Sally and Steve can paint the room in about 3 hours and 5 minutes

Answer: C(x) = 13x +95
Step-by-step explanation:
Here's the remainder of the question:
If C(x) represents the total cost and x represents the number of people attending the banquet, which equation shows the total cost? A C(x)=95x – 13 B C(x)=13x – 95 C C(x)=95x +13 D C(x)=13x +95
Based on the information given in the question, the total cost will be:
= 95 + 13(x)
= 95 + 13x
Therefore, the correct answer will be C(x)=13x +95

Alice is searching online for tickets to a knicks game. Two weeks ago, the cost was $30. Now the cost is $39. What is the percent increase
Given:
Two weeks ago, the cost of tickets = $30
Now, the cost of tickets = $39
To find:
The percent increase.
Solution:
We have,
Initial value = $30
New value = $39
Formula for percentage increase is:
[tex]\%\text{increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]
Using this formula, we get
[tex]\%\text{increase}=\dfrac{39-30}{30}\times 100[/tex]
[tex]\%\text{increase}=\dfrac{9}{3}\times 10[/tex]
[tex]\%\text{increase}=3\times 10[/tex]
[tex]\%\text{increase}=30[/tex]
Therefore, the percent increase in the cost of tickets is 30%.
A cake has circumference of 2517 25 1 7 inches. What is the area of the cake? Use 227 22 7 for π π . Round to the nearest hundredth. AWNSER
Answer:
22in²
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Circumference = 25 (1/7)
As we know,
Circumference of a circle = 2πr
By solving this we get
Radius (r) = 4in
Now. we can calculate the area by using following formula,
Area = πr²
By putting the value, we get
Area = (22/7) × 4²
= 22/7 × 16
= 352÷16
Area = 22in²
What is the surface area of this composite solid?
Use 11.3 meters for the slant height of the triangular prism.
Enter your answer in the box.
__m²
Composite made up of a rectangular prism surmounted by a triangular prism. The rectangular prism has dimensions of 16 meters wide by 20 meters long by 12 meters high. The triangular prism has dimensions of 16 meters wide by 20 meters long with a triangular altitude of 8 meters high.
Answer:
1764 m²Step-by-step explanation:
Refer to attached picture.
All given dimensions are given on the picture (not to scale).
Since altitude of the triangle and slant height is given, we can find the base of the triangle using Pythagorean:
[tex]b/2 = \sqrt{11.3^2-8^2} = \sqrt{64} = 8m, \\b = 16 m[/tex]It has 9 faces and the total surface area is:
S = 16*20 + 2(20*12) + 2(20*11.3) + 2(16*12) + 2(1/2*8*16) = 1764 m²Greg uses a triangular area of his back yard as a garden.If the area if his garden 1.248 square feet,whats the area of the garden?
Answer:
192 ft²
Step-by-step explanation:
Area of rectangular backyard = 1248 ft²
Width of backyard = 52 ft
Length = x
Area of rectangular backyard = Length * width
1248 = x * 52
x = 1248 / 52
x = 24 feets
Hence, x = height of triangular garden
Area of triangle = 1/2 base * height
Area = 1/2 * 16 * 24
Area = 192 ft²
Determine the slope
Answer:
1/3
Step-by-step explanation:
We use the formula y2-y1/x2-x1. The two points that I would use are (3,-1) and (-3,-3). This means that the equation will be -3--1/-3-3. This is equal to -2/-6. This is also equal to 1/3. Therefore, the slope is 1/3.

Jayna used the distributive property to simplify the expression 4(a + 2) and got(4a + 2). Do you agree with Jayna?
Answer:
No
Step-by-step explanation:
I would not agree with Jayna because using the distributive property, you can get:
4(a + 2) = 4(a) + 4(2) = 4a + 8
Jayna did not get the right answer because she did not distribute the 4 to the 2 in a + 2 and she only multiplied a by 4.
Isaac finished eight of the ten homework problems. Phil has finished of the homework. How many more problems did Isaac finish?
Answer:
-2
Step-by-step explanation:
If Issac has finished 8/10 problems in the homework, and Phil has completed all of it, it can be concluded that Phil completed 10/10. 10/10 would equal a whole, or in this case, the entire homework. If Issac completed 8 problems, and Phil completed 10, subtract both values to find that Issac completed -2 more problems than Phil.

Which function is best represented by this graph?
A. y = 1/2x + 6
B. y = −2x + 3
C. y = 2x + 6
D. y = −1/2x + 3
Answer:
d
Step-by-step explanation:
not a bc it has to be negative
not c bc its has to be negative
not b bc the slope is -1/2
IT'S D
Answer:
D
Step-by-step explanation:
from the picture, we know that the slope is negative to begin, since the line is going on a downward direction from left to right. this eliminated A and C instantly.
Now we also can see the graph crossed at 3 for the y intercept, which is another reason to eliminate A and C.
we must then find the show of the line.
let us use to point (0,3) since this is the y intercept and (6,0) since this is the x intercept. to find the slope, m, at must use the equation
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
so, let's label (0,3) as point 1 and (6,0) as point two. then,
x1 = 0
y1= 3
and
x2= 6
y2=0
Now we just plug in and simplify.
[tex] m = \frac{0 - 3}{6 - 0} = \frac{ - 3}{6} = - \frac{1}{2} [/tex]
we now have our slope and y intercept, so we can plug them into our equation
[tex]y = mx + b[/tex]
where m is the slope and b is the y intercept.
our equation is thus
[tex]y = - \frac{1}{2} x + 3[/tex]
so, the answer is D

Someone please help 20 points!
please help me PLEASE
Answer:
The answers are A, B and C.
Step-by-step explanation:
To solve the inequality you first have to use Distributive Property. You should get -3k + (-21) > -57
Next Divide 21 on both sides. -57/21 is -36
You should have -3k > -57
Divide -3 on both sides. -57/-3 is 12
You should end up with k > 12
And you never used -5, 0 or 8 in the equation and the question asks to choose the following that isn't included in the solution so your answers are A, B and C.
