Answers
Answer:
265 is the snakiest number
Step-by-step explanation:
36 = 3 x 12 and 96 = 8 x 12 so LCM is 3 x 8 x 12 = 288
288 = 32x9 = 36x8 = 48x6 = 96x3
288 - 28 = 260

A 2 1/2 foot by 8-foot concrete wall is to be built using concrete blocks. Find the area of the wall.
Answers
20 foot² is the area of the wall.
What does a math area mean?
The amount of space occupied by a flat (2-D) surface or an object's shape is known as its area. On a sheet of paper, use a pencil to create a square. It has two dimensions. Its Area refers to the area that the shape occupies on the paper. Consider your square as being composed of smaller unit squares.Length of concrete wall = [tex]2\frac{1}{2}[/tex] foot
Breadth of concrete wall = 8 foot
Since, area means product of dimensions so we use the formula mentioned below:
Area of the concrete wall = length× breadth
= [tex]2\frac{1}{2}[/tex] * 8
= 5/2 * 8
= 5 * 4 = 20 foot²

David and his children went into a grocery store and he bought $7.50 worth of apples and bananas. Each apple costs $0.75 and each banana costs $0.50. He bought 5 more bananas than apples. By following the steps below, determine the number of apples, x, and the number of bananas, y, that David bought.
DETERMINE THREE WAYS TO HAVE 5 MORE BANANAS THAN APPLES
Answers
Answer:
Let the number of apples and bananas bought be x and y respectively.
x + 5 = y ------ equation (1)
0.75x + 0.50y = 7.50 ------ equation (2)
Substitute equation (1) into equation (2):
0.75x + 0.50(x+5) = 7.50
0.75x + 0.50x + 2.50 = 7.50
1.25x = 5
∴x = 4
Substitute x = 4 into equation (1):
∴y = 4+5
= 9
∴David bought a total of 4 apples and 9 bananas.

Given g(x) = −2x^2 + 3x + 20, find g(0), g(−2.5), g(4), g(0.75), g(20)
Answers
The functions g(0) = 20, g(−2.5) = 0, g(4) = 0, g(0.75) = 21.125, g(20) = -720 as a result of the mapping with the function g(x) = −2x² + 3x + 20
What is a function?A function is a mapping whose codomain is the set of real numbers. It can also be defined as a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
From the function g given as g(x) = −2x² + 3x + 20, by careful mapping we have the following;
put 0 for values of x
g(0) = -2(0)² + 3(0) + 20
g(0) = 20.
put -25 for values of x
g(-25) = -2(-25)² + 3(-25) + 20
g(-25) = -12.5 - 7.5 + 20
g(-25) = 0
put 4 for values of x
g(4) = -2(4)² + 3(4) + 20
g(4) = -32 + 12 + 20
g(4) = 0
put 0.75 for values of x
g(0.75) = -2(0.75)² + 3(0.75) + 20
g(0.75) = -1.25 + 2.25 + 20
g(0.75) = 21.125
put 20 for values of x
g(20) = -2(20)² + 3(20) + 20
g(20) = -800 + 60 + 20
g(20) = -720
Therefore, by proper mapping of the function g(x) = −2x² + 3x + 20, we derived g(0) = 20, g(−2.5) = 0, g(4) = 0, g(0.75) = 21.125, and g(20) = -720.

Timothy plans to add a railing parallel to a flight of stairs that goes down to the basement in his house. Each step has the dimensions shown in the sketch.
What will be the length of the railing?
Answers
The length of the railing is 105.81 inches.
Given,
The stair has 7 steps
The rise of each step = 8.5 inches
The tread of each step = 12.5 inches
Slope of each step = x
We have to find the length of the railing.
Length of railing = 7x
Then,
Slope of step, x can be determined using Pythagorean theorem.
Let rise be the height of the right angled triangle and tread be the base of the triangle
Then,
Hypotenuse= Slope, x = [tex]\sqrt{Rise^{2} + Tread^{2} }[/tex]
x = [tex]\sqrt{8.5^{2}+ 12.5^{2} }[/tex]
x = [tex]\sqrt{72.25 + 156.25}[/tex]
x = √228.5
x = 15.12 inches
That is,
The slope, x of one step is 15.12 inches
Now,
Length of the railing = 7x = 7 × 15.12 = 105.81 inches
Therefore,
The length of the railing is 105.81 inches.

Which of the following is a good point estimator for the population variance?
Answers
A good point estimator for the population variance is: s².
What is a two-tailed test?A two-tailed test can be defined as a type of hypothesis test in which a rejection of the null hypothesis occurs for values of the point estimator in either tail of the sampling distribution.
In Statistics, the basis of an inference about the population is usually used to determine statistical inference based on all of the statistics that are calculated from samples.
This ultimately implies that, the sample mean should be close to the population mean, the sample proportion should be close to the population proportion, and the sample standard deviation should be close to the population standard deviation.
In this context, we can logically deduce that standard deviation (s²) is considered as a good point estimator for the population variance.

-1/4-a-4=7/4a-3
solving equations with one unlike equations
Answers
Answer:
a = -5/11
Step-by-step explanation:
You want to solve the equation -1/4-a-4=7/4a-3.
SolutionThe first step in solving this 3-step equation can be to add the opposite of (-a) so that the variable 'a' appears only on one side of the equation:
-1/4 -a -4 +a = 7/4a -3 +a
-17/4 = 11/4a -3 . . . . . . . . . . . simplify
The second step is to add the opposite of the constant (-3) so that the constant is on one side of the equation, and the variable is on the other side.
-17/4 +3 = 11/4a -3 +3
-5/4 = 11/4a . . . . . . . . . . simplify
The third step is to multiply by the inverse of the coefficient of the variable:
(4/11)(-5/4) = (4/11)(11/4a)
-5/11 = a . . . . . . . . . . . . . . . simplify
Check-1/4 -(-5/11) -4 = (7/4)(-5/11) -3
-17/4 +5/11 = -35/44 -3
(-187 +20)/44 = (-132 -35)/44
