Answer:
[tex] \alpha = 108\degree, \: \beta = 72\degree [/tex]
Step-by-step explanation:
α and β are Supplementary (given)
[tex] \therefore \alpha + \beta = 180\degree.... (1)[/tex]
It is given that:
[tex] \alpha= \frac{3}{2} \beta[/tex]
Plugging the value of α in equation (1), we find:
[tex] \frac{3}{2} \beta + \beta = 180\degree[/tex]
[tex]\therefore \frac{3+2}{2} \beta = 180\degree[/tex]
[tex]\therefore \frac{5}{2} \beta = 180\degree[/tex]
[tex]\therefore \beta = 180\degree\times \frac{2}{5}[/tex]
[tex]\therefore \beta = 72\degree[/tex]
[tex]\implies \alpha= \frac{3}{2} \times 72\degree= 108\degree [/tex]
So,
[tex] \alpha = 108\degree, \: \beta = 72\degree [/tex]

Answer:
sample
or spot check

there are quite a number of different terms that can be used depending on the specific scientific field you are working in.

The equation y = (-16t – 2)(t-1) represents the height in feet of a beach ball thrown by a child as a function of time, `t`, in seconds.
from What height is the beach ball thrown? explain or show your reasoning
2 ft
Step-by-step explanation:
The height from which the beach ball was thrown happens when t = 0. So setting t = 0 to get y, we get
y = [-16(0) - 2](0 - 1)
= (-2)(-1)
= 2 ft
Therefore, the ball was thrown from a height of 2 ft.

a regular sheet of letter (printing) paper measrues 8.5 inches by 11 inches. you want to cut out squares from each corner that it may be folded up to produce an open - top box. What are the dimensions of the square cut outs that will result in a box of maximum volume
Answer:
The dimensions of the square, that will result in a box of maximum volume is a square with side length of approximately 1.585 inches
Step-by-step explanation:
The given dimension of the steel sheet are;
The width = 8.5 inches
The length = 11 inches
Let 'x' represent the side length of the squares cut out, we have;
The length of the box formed, l = 11 - 2·x
The width of the box formed, w = 8.5 - 2·x
The height of the box, h = x
The volume of the box, V = (11 - 2·x) × (8.5 - 2·x) × (x) = 4·x³ - 39·x² + 93.5·x
The maximum or minimum volume is found from dV/dx = 0 at max. or min.
dV/dx = d(4·x³ - 39·x² + 93.5·x)/dx = 12·x² - 78·x + 93.5 = 0
Which gives;
x = (78 ± √((-78)² - 4×12×93.5))/(2 ×12)
x = 4.915 or 1.585
When x = 4.915, V = 4 × 4.915³ - 39 × 4.915² + 93.5 × 4.915 = -7.65
When x = 1.585, V = 4 × 1.585³ - 39 × 1.585² + 93.5 × 1.585 = 66.15
Therefore, the local maximum occurs at x ≈ 1.585
Therefore, the dimensions of the square, 'x' that will result in a box of maximum volume is x ≈ 1.585 inches.

A data set is Normally distributed with a mean of 25 and a standard deviation of 8. If you calculate the standard score of every observation in this data set, the resulting scores will have a distribution that has
Answer:
The answer is "A mean of 0 and a standard deviation of 1".
Step-by-step explanation:
The standard answer of its following formula is calculated by:
[tex]\to z=\frac{X-\mu}{\sigma}[/tex]
Its standard score relates to the sampling distribution with the normal distribution average standard variation of 0 and 1, correspondingly. The mean for a standard scoring is 0, and the normal deviation is 1. that's why the mean=0, standard deviation=1.

1.) The check number on a check:
A.) identifies the bank and is located at the bottom left corner of the check.
B.) identifies the bank and is located at the top right corner of the check.
C.) identifies the transaction and is located at the bottom left corner of the check.
D.) identifies the transaction and is located at the top right corner of the check.
E.) None of these choices are correct.
Answer:
D) Identifies the transaction and is located at the top right corner of the check
Step-by-step explanation:
The check number on a check is the number located at the top right corner of the check, and it can also be found at the bottom of the check, located in lower right corner after the routing number and the account number
The check number aids in the tracking and identifying bank transactions such as to identify checks that the bank has processed and to know outstanding checks that are yet to be processed.
The check number also aids in balancing of the checkbook.
Therefore, the check number on a check identifies the transactions and is located at the top right corner of the check.
Can yall get me the volume calculations for the 3 shapes? Thank you! | Geometry
Figure 1
Name = Coneh = 4 unitsd = 8Since the diameter is 8, this cuts in half to the radius of r = 4. Plug the given values into the cone volume formula below
V = (1/3)*pi*r^2*h
V = (1/3)*pi*(4)^2*4
V = (64/3)pi ..... exact volume in terms of pi
V = (64/3)*3.14
V = 66.98667 .... approximate volume when using pi = 3.14
========================================================
Figure 2
Name = cylinderh = 4d = 8 which cuts in half to r = 4V = volume of cylinder
V = pi*r^2*h
V = pi*4^2*4
V = 64pi ..... exact volume
V = 64*3.14
V = 200.96 .... approximate volume when using pi = 3.14
========================================================
Figure 3
Name = rectangular prismb = 32h* = 12h = 4b and h* are dimensions along the bottom face, aka floor
h is the height or vertical dimension of the 3D room
V = volume of rectangular prism = volume of 3D room
V = length*width*height
V = (b)(h*)(h)
V = (32)(12)(4)
V = 1536 is the exact volume
There is no approximate volume for this figure because the result above is an integer.
========================================================
Combining the figures
Adding up the volumes for figures 1 through 3 gets us
(64/3)pi + 64pi + 1536 = (256/3)pi + 1536
The exact total volume in terms of pi is (256/3)pi + 1536
If we used pi = 3.14, then it leads to
(256/3)pi + 1536 = (256/3)*3.14 + 1536 = 1803.94667
The approximate total volume of all three figures combined is roughly 1803.94667 cubic units

if a, b, c, and d represent positive real numbers, what is the inequality when solved for x?
The inequality equation is x ≥ ( by - c - d ) / a
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
by - d ≤ ax + c be equation (1)
On simplifying the equation , we get
Subtracting c on both sides of the equation , we get
by - d - c ≤ ax
And , ax ≥ by - d - c
Divide by a on both sides of the equation , we get
x ≥ ( by - c - d ) / 2
Hence , the inequality is x ≥ ( by - c - d ) / a

Use the distance formula to find the distance to the nearest tenth, from R17, -2) to W(-2, 3).
Answer:
17.7
Step-by-step explanation:
I'm assuming you meant R(17, -2) to W(-2, 3). Here the x-coordinate changes by 17 - (-2), or 19, and the y-coordinate by 5. Think of these as the legs of a right triangle. The distance between these points is the length of the hypotenuse of this triangle: d = √(5^2 + 17^2)
or √314, which, to the nearest tenth is 17.7.

Complete the missing parts of the table for the following function. y=7x
Answers: 49, 1, 49
Those values go in the blanks from left to right
=====================================================
Explanation:
The rule we use is x^(-k) = 1/(x^k)
That means if we're evaluating something like 7^(-1), then it's the same as 1/(7^1) = 1/7 which explains how x = -1 leads to y = 1/7.
Similarly, 7^(-2) = 1/(7^2) = 1/49 is the y value when x = -2. So you'll type 49 into the first box to fill in that missing denominator.
Raising any nonzero value to the zeroth power leads to 1. That rule is x^0 = 1 where x can be anything you want but it can't be zero. Therefore 7^0 = 1 goes in the second box.
Lastly, 7^2 = 7*7 = 49 will go in the third box.
