Natalia is writing a recursive formula to represent the sequence.
8, 12, 18, 27, ...
What value should she use as the common ratio in the formula?
1/4, 2/3, 3/2, 4/1
Answer:
The answer to your equation would be 1.5.
Step-by-step explanation:
The common ratio if there exists one can be found by choosing a term and dividing by its previous term
So does 12/8=18/12=27/18? Put each into the calculator. If they are equal fractions then this sequence is geometric and has a common ratio.
Each of the fractions are equal to 1.5.
Therefore the commom ratio is 1.5.

Answer:
The correct answer is: Option 2
[tex]y+1 = \frac{8}{9}(x+4)[/tex]
Step-by-step explanation:
Point-slope form of an equation is given by:
[tex]y-y_1= m(x-x_1)[/tex]
Here m is the slope of the line and (x1,y1) is the point from which the line passes
Given points are:
(-4,-1) and( 5,7)
Slope is given by the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\m=\frac{7-(-1)}{5-(-4)}\\m = \frac{7+1}{5+4}\\m = \frac{8}{9}[/tex]
Now we will put the first point and slope in general form of equation of line
[tex]y-(-1) = \frac{8}{9}(x-(-4))\\y+1 = \frac{8}{9}(x+4)[/tex]
Hence,
The correct answer is: Option 2
[tex]y+1 = \frac{8}{9}(x+4)[/tex]
In ΔCDE, \text{m}\angle C = (5x+18)^{\circ}m∠C=(5x+18) ∘ , \text{m}\angle D = (3x+2)^{\circ}m∠D=(3x+2) ∘ , and \text{m}\angle E = (x+16)^{\circ}m∠E=(x+16) ∘ . Find \text{m}\angle D.M∠D.
Answer:
Angle D = m∠D= 50°
Step-by-step explanation:
In ΔCDE we are given: 3 angles
m∠C=(5x+18) ∘
m∠D=(3x+2) ∘
m∠E=(x+16) ∘ .
The sum of angles in a triangle = 180°
Hence:
m∠C + m∠D + m∠E = 180°
(5x+18)° + (3x+2)° + (x+16)° = 180°
5x + 18 + 3x + 2 + x + 16 = 180°
5x + 3x + x + 18 + 2 + 16 = 180°
9x +36= 180°
Subtract 36 from both sides
9x + 36 - 36 = 180° - 36°
9x = 144°
x = 144°/9
x = 16
From the above question, we are asked to find:angle D (m∠D )
Hence:
m∠D=(3x+2)°
m∠D=( 3 × 16 + 2)°
m∠D=(48 + 2)°
m∠D= 50°
this is due in 15min and welp don't know this exactly can sum1 help me

A recipe calls for 2 cups of sugar, 3 cups of flour, 1 cup of butter, and 1/2 a cup of chocolate chips. What is the ratio of flour and butter to sugar?
Answer:
2 : 1
Step-by-step explanation:
Recipe :
Sugar = 2 cups
Flour = 3 cups
Butter = 1 cup
Chocolate chips = 1/2 cup
ratio of flour and butter to sugar?
Total cups of flour plus butter = (3 + 1) = 4 cups
Cups of sugar = 2 cups
ratio of flour and butter to sugar :
4 cups : 2 cups
= 2 : 1

James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply
Answer:
When x=2, both expressions have a value of 18.
The expressions have equivalent values for any value of x.
The expressions have equivalent values if x=8
Step-by-step explanation:
James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply. 7 x + 4 and 3 x + 5 + 4 x minus 1
When x = 2, both expressions have a value of 18.
7x + 4
= 7(2) + 4
= 14 + 4
= 18
3x + 5 + 4x - 1
3(2) + 5 + 4(2) - 1
6 + 5 + 8 - 1
= 18
The expressions are only equivalent for x = 4 and x = 6.
• This is not true because the expression is also equivalent for x = 2
The expressions are only equivalent when evaluated with even values.
When x = 1
7x + 4
7(1) + 4
= 7 + 4
= 11
3x + 5 + 4x - 1
3(1) + 5 + 4(1) - 1
3 + 5 + 4 - 1
= 11
The expressions have equivalent values for any value of x.
Yes, it has an equivalent value at any value of x
The expressions should have been evaluated with one odd value and one even value.
When x = 0, the first expression has a value of 4 and the second expression has a value of 5.
7x + 4
7(0) + 4
= 0 + 4
= 4
3x + 5 + 4x - 1
3(0) + 5 + 4(0) - 1
0 + 5 + 0 -1
= 4
The expressions have equivalent values if x = 8.
7x + 4
7(8) + 4
56 + 4
= 60
3x + 5 + 4x - 1
3(8) + 5 + 4(8) - 1
24 + 5 + 32 - 1
= 60

Step-by-step explanation:
A construction company is starting to build a new house. They need to put tape around the site to begin. The new home site is 202020 meters wide by 404040 meter long rectangle. The company already has 100100100 meters of tape. How much more tape does the company need to tape the site?
Answer:
20 meters
Step-by-step explanation:
A construction company is starting to build a new house. They need to put tape around the site to begin. The new home site is 20 meters wide by 40 meter long rectangle. The company already has 100 meters of tape. How much more tape does the company need to tape the site?
We would have to find the perimeter of this rectangle
Perimeter fo a rectangle = 2L + 2W
In the above question,
L = Length = 40 m
W = Width = 20 m
Hence:
Perimeter = 2(40m) + 2(20m)
= 80m + 40m
= 120m
Hence, he would need 120 meters of tape
From the above Question, the company already has 100m
Hence, the amount of tape that the company needs more =
120m - 100m = 20 m
what is the slope of 4x + 4y = 8?
Answer:
m=-1
Step-by-step explanation:
4x-8=-4y
x-2=-y
-x+2=y
Answer:
m=-1
Step-by-step explanation:
It is easiest to put the equation into slope-intercept form first.
4x+4y=8
4y=-4x+8
y=-x--2
The slope of the line is -1
Lou's car had 6.6 gallons in the 16- gallon tank on the coldest day of the year . Lou filled the tank with gas that cost 3.70 per gallon how much money did lou spend
Answer: $33.48
Step-by-step explanation:
Given that:
Capacity of car tank =. 16 gallons
Gallons of already filled = 6.6 gallons
Amount left of tank capacity = 16 - 6.7
Amount left of tank capacity = 9.3 gallons
Cost of gas per gallon = $3.60
Hence, amount spent in gas will be
Amount left of tank capacity * cost per gallon of gas
= 9.3 gallons * $3.60
= $33.48
Total amount spent on gas = $33.48

Leila bought 3 bananas, which weighed a total of Three-fourths of a pound. If each banana weighed the same amount, what is the weight of each banana? StartFraction 1 Over 12 EndFraction of a pound StartFraction 1 Over 9 EndFraction of a pound One-fourth of a pound One-third of a pound
Answer:
[tex]Each\ Weight = \frac{1}{4}[/tex]lb
Step-by-step explanation:
Given
[tex]Weights = \frac{3}{4}lb[/tex]
[tex]Bananas = 3[/tex]
Required
Determine the weight of each
To do this, we simply divide the total weight by the number of bananas.
[tex]Each\ Weight = \frac{3}{4}/3[/tex]
Convert to multiplication
[tex]Each\ Weight = \frac{3}{4} * \frac{1}{3}[/tex]
[tex]Each\ Weight = \frac{1}{4}[/tex]
Hence, each banana weighs 1/4 of a pound

Select the correct locations on the graph
select the lines that represent functions
Step-by-step explanation:
Using the vertical line test, we can see which lines are functions, and which are not. If a vertical line were to hypothetically appear, would it touch more than one part of the line? If so, it is not a function.
The lines outlined in a black box are the correct answers.
