divide 10 dollars by 6 avacados to get your unit rate, and then multiply that by 12 to get your cost.
10/6 is 3/2
3/2 times 6 is 18
so 18 dollars for 12 avacados
Answer: $20 if six avocados are $10 add 10+ 10= 20
Can you guys help? I really don’t know
Answer:
x = 1.4
Step-by-step explanation:
6 - 2x = 8(x -1)
6 - 2x = 8x - 8
collecting like terms
-2x - 8x = -8 - 6
-10x = -14
10x = 14
dividing both sides by 10
x = 14/10
x = 1.40 (2d.p)

A researcher wishes to estimate the proportion of adults who have high-speed Internet access. What size sample should be obtained if she wishes the estimate to be within 0.03 with 90% confidence if (a) she uses a previous estimate of 0.34?(b) she does not use any prior estimates? n=_____(Round up to the nearest integer.)
Answer:
675 samples
752 samples
Step-by-step explanation:
Given that :
α = 90%
E = 0.03
Previous estimate (p) = 0.34
Estimated sample proportion (n)
n = p *q * (Zcritical /E)
Zcritical = α/2 = (1 - 0.9) /2 = 0.1 / 2 = 0.05
Z0.05 = 1.645 ( Z probability calculator)
q = 1 - p = 1 - 0.34 = 0.66
n = 0.34 * 0.66 * (1.645/0.03)^2
n = 674.70
n = 675
B.) without prior estimate given ;
p and q should have equal probability
Hence ;
p = 0.5 ; q = 0.5
n = 0.5 * 0.5 * (1.645/0.03)^2
n = 751.67361
n = 752

Let's look at the factors of 28.
1,28
2,14
4,7
We see that 4 and 7 add to make 11, but not -11. Well, we can just make both of them negative and then it will be -11 and their product will still be 28. Our numbers are -4 and -7.
the 2 numbers are 5, and 10

Answer:
27°Step-by-step explanation:
The angle at the intersection of lines q and r is 90° as they are perpendicular
117° is the exterior angle of the triangle
Exterior angle is:
117° = 90° + x as per its propertySolving the equation we get:
x = 117° - 90°x = 27°Answer: 27

USING ALGEBRA TILES Write the sum of the two algebraic expressions modeled by the algebra tiles. Let x be the variable. Then use the algebra tiles to simplify the expression. math
Answer:
the picture is super blurry can u change the picture and I'll do my best to answer it :)
Step-by-step explanation:
The sum of the two algebraic expressions modeled by the algebra tiles is 3x - 1.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
We have to determine the sum of the two algebraic expressions modeled by the algebra tiles.
Let the variable would be x.
List the algebraic expression by the algebra modeling tiles
⇒ (2x - 6) + (x +5)
⇒ 2x - 6 + x +5
Rearrange the terms and apply the arithmetic operation
⇒ 3x - 1
Therefore, the sum of the two algebraic expressions modeled by the algebra tiles is 3x - 1.

Let g(x) = -2(3x + 4)(x - 1)(x – 3)2 be a polynomial function.
1. Sketch a graph of the polynomial.
2. Name all horizontal and
vertical intercepts of the graph.
3. State the end behavior of g.
Answer:
Hope this helped a little :)
Step-by-step explanation:
The all horizontal and vertical intercepts of the graph are x-intercept(s): (-4/3, 0), (1,0), (3,0) and y-intercept(s): (0,72).
The given function is g(x) = -2(3x+4)(x-1)(x-3)².
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
1) The sketch a graph of the polynomial is given below.
2) To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
x-intercept(s):
(-4/3, 0), (1,0), (3,0)
y-intercept(s): (0,72)
3) Use the degree and the leading coefficient to determine the behavior.
Falls to the left and falls to the right
Therefore, the all horizontal and vertical intercepts of the graph are x-intercept(s): (-4/3, 0), (1,0), (3,0) and y-intercept(s): (0,72).

The required domain of the function given is all real numbers. Option B is correct.
Given that,
To determine the domain of the given function shown in the graph.
The domain is defined as the values of the independent variable for which there is a certain value of the dependent variable exists in the range of the function.
Here,
As shown in the graph function is given as y = 1.5,
So the domain x for the given function is given as all real values of the x from -∞ to +∞.

• Washington Avenue is represented by the line x = 3.
.
Lincoln Avenue passes through the point (5,2).
Lincoln Avenue and Washington Avenue are parallel.
line
Lincoln Avenue is represented by the line
Answer:
Lincoln Avenue is represented by the line [tex] x = 5 [/tex], which is a VERTICAL LINE.
Step-by-step explanation:
The equation of the line of Washington Avenue, x = 3, suggests that the line is a vertical line, since a vertical line takes the form of x = k, where k is the value x would always take and also it is the x-intercept.
Given that Lincoln Avenue passes through the point (5, 2), and its line is parallel to that of Washington Avenue, it means that the line do not intercept each other, and Lincoln Avenue is also a vertical line.
Therefore, if Lincoln Avenue passes through (5, 2), its line can be represented also in the form, x = k. Where, k is the value that x would always take, and also, it is the x-intercept. x would always be 5 even when y changes.
Therefore, the equation of the line that represents Lincoln Avenue would be:
✅ [tex] x = 5 [/tex]
✅This is also a Vertical line.
