Which of the following inequalities is graphed on the coordinate plane?
A. y > 1/2x - 1/2
B. y is less than or equal to 1/2x - 1/2
C. y is greater than or equal to 1/2x - 1/2
D. y < 1/2x - 1/2
Answers
Answer:
Option C
Step-by-step explanation:
Equation of any line is of the form y=mx+b where m is the slope and b the y intercept.
The given line has y intercept [tex]\frac{-1}{2}[/tex] and slope as [tex]\frac{1}{2}[/tex]
Hence equation of given line is :
[tex]y= \frac{1}{2}x-\frac{1}{2}[/tex]
Taking point (0,0) to check the inequality we have:
0≥[tex]\frac{-1}{2}[/tex]
The statement is true so option C [tex]y\geq \frac{1}{2} x-\frac{1}{2}[/tex] is right .

Problem page a delivery truck is transporting boxes of two sizes: large and small. the large boxes weigh 45 pounds each, and the small boxes weigh 15 pounds each. there are 120 boxes in all. if the truck is carrying a total of 3300 pounds in boxes, how many of each type of box is it carrying?
Answers
l= number of large boxes
equation 1: s+l=120
equation 2: 15s+45l=3300
solve by elimination, multiply equation 1 by -15.
-15(s+l=120) = -15s-15l=-1800 add to equation 2.
-15s+15s-15l+45l=-1800+3300 = 30l=1500
30l=1500 , l=50
s+l=120, s+50=120 --> s=70

Carl deposited $5,142 into a savings account 20 years ago. The account has an interest rate of 3.8% and the balance is currently $10,994.58. How often does the interest compound? daily monthly quarterly annually
Answers
The answer is it is compounded monthly which is 365/yr.
This is done using trial and error but I got it right at the first try.
Solution:
A = P (1+r/n) ^nt
Where:
A is the accrued amount or also known as the future value
P is the principal amount = $5,142
r is the nominal interest rate = 0.038
n is the number of compounding units = 365
t is time = 20
A = 5,142 (1 + 0.038/365) ^ 365(20)
= 5,142 (1.0001041095890410958904109589041)^7300
= 5.142 (2.13819163)
= $10994.58
What is the area of the trapezoid shown? (1) angle a = 120 degrees (2) the perimeter of trapezoid abcd = 36?
Answers
Neither statement alone is sufficient to determine the area of the trapezoid.
Explanation:The area of a trapezoid can be found using the formula:
Area = (1/2) * (sum of parallel sides) * height
To find the area of the trapezoid, we need the lengths of the parallel sides and the height.
(1) The given angle does not provide information about the lengths of the sides, so it is not sufficient to find the area.
(2) The perimeter of the trapezoid does not directly give information about the lengths of the sides, so it is also not sufficient to find the area.
Therefore, neither statement alone is sufficient to determine the area of the trapezoid.

The sun is 30 ∘ above the horizon. it makes a 60 m -long shadow of a tall tree. how high is the tree
Answers
To calculate the height of a tree with a 60-meter long shadow when the Sun is 30 degrees above the horizon, use the tangent trigonometric function. The tree's height is calculated to be around 34.62 meters tall.
Explanation:The student is asking how to calculate the height of a tree given the length of its shadow when the Sun is 30 degrees above the horizon. This is a trigonometry problem involving a right-angled triangle, where the tree represents the opposite side, the shadow represents the adjacent side, and the angle given is the angle of elevation of the Sun. Since we have the angle and the length of the adjacent side, we can use the tangent trigonometric ratio to find the height of the tree. The tangent of an angle in a right-angled triangle is the ratio of the opposite side to the adjacent side (tangent = opposite/adjacent).
Therefore, the tree is approximately 34.62 meters tall.

John's credit card company calculates a finance charge based upon a periodic rate of 1.75% on all unpaid balances. If John has an unpaid balance of $475, determine the finance charge that he will be assessed.
A. $8.31
B. $349.00
C. $346.30
D. $469.33
Answers
Final answer:
The finance charge for John is calculated by multiplying his unpaid balance by the periodic rate. The calculation results in a finance charge of $8.31, which is option A.
Explanation:
John's finance charge on his credit card, based on a periodic rate of 1.75% on an unpaid balance of $475, can be calculated using the formula: Finance Charge = Periodic Rate × Unpaid Balance. To find the finance charge, multiply 1.75% (or 0.0175 in decimal form) by $475. Therefore, the finance charge would be 0.0175 × $475 = $8.3125. When rounded to the nearest cent, this is $8.31, which corresponds to option A.
An urn contains six chips, numbered 1 through 6. two are chosen at random and their numbers are added together. what is the probability that the resulting sum is equal to 5?
Answers
Final answer:
The probability of drawing two chips from an urn numbered 1 through 6 such that their sum is 5 is 4/15, since there are four favourable outcomes (1,4), (2,3), (3,2), and (4,1) out of the total 15 possible combinations.
Explanation:
The question involves calculating the probability of drawing two chips from an urn, each numbered 1 through 6, such that their sum equals 5. To solve the problem, let's consider all possible combinations of two different chips that can be drawn at random:
(1, 4)(2, 3)(3, 2)(4, 1)There are 4 favourable combinations that result in a sum of 5. As each chip can be drawn only once, the total number of pairs can be given by the combination formula C(n, k) = n! / (k!(n-k)!)), where n is the total number of chips and k is the number of chips drawn. In this case, C(6, 2) = 6! / (2!4!) = 15, and so there are 15 possible pairs that can be drawn from our urn.
Therefore, the probability of getting a sum of 5 is the number of favourable outcomes divided by the total number of outcomes, which is 4 favourable combinations divided by 15 possible combinations, resulting in a probability of 4/15.

Angles STU and STR are supplementary angles.
Angles R and STR are congruent.
m<STU + m<STR = 180
8x + m<STR = 180
m<STR = 180 - 8x
m<R = m<STR = 180 - 8x
m<RST + m<R + m<STR = 180
7x - 54 + 180 - 8x + 180 - 8x = 180
-9x + 360 = 180
-9x = -126
x = 14
also m < SRT = 180-8x ( because side RS = side ST, so isosceles triangle)
So
7x - 54 + 180 - 8x = 8x (ext. angle of triangle =sum of opposite internal angles)
7x - 8x - 8x = -180 + 54 = -126
-9x = -126
x = 14 answer

Which is the graph of 4x – 3y = 12?
Answers
Answer:
its the last graph pictured
The graph of 4x - 3y = 12 is given below.
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Linear equations may include one or more variables.
The given linear equation is 4x - 3y = 12.
Rearranging it into slope intercept form, we get,
y = 4/3 x - 4
In order to find the points through which it passes, put some of the values of x.
When x = -3, y = -4 - 4 = -8
When x = 0, y = 0 - 4 = -4
When x = 3, y = 4 - 4 = 0
When x = 6, y = 8 - 4 = 4
...........
So the graph passes through (-3, -8), (0, -4), (3, 0) and (6, 4).
Hence the graph of the given equation is given below.
