You will place the sticker [tex]\frac{5}{8}[/tex] inches from the edge of the switch board
Step-by-step explanation:
Given data:
Sticker’s length = [tex]2 \frac{1}{2}[/tex]
Breadth of switch box = [tex]3 \frac{3}{4}[/tex]
Subtracting the above value, we get
[tex]\text { Switch Box's total area }=3 \frac{3}{4}-2 \frac{1}{2}=\frac{15}{4}-\frac{5}{2}=\frac{15-10}{4}=\frac{5}{4}[/tex]
Divided [tex]\frac{5}{4}[/tex] by 2 gives you the distance from the edge if you put the sticker in the centre). Therefore,
[tex]\frac{\left(\frac{5}{4}\right)}{\left(\frac{2}{2}\right)}=\frac{5}{8}[/tex]
So, will place the sticker [tex]\frac{5}{8}[/tex] inches far from the edge of the switch board.

(A) x + 32 < 50
(B) 5x + 32 < 50
(C) 5 + x + 32 < 50
(D) x/5 + 32 < 50
Answer:
5x + 32 < 50
Step-by-step explanation:
On a particular airline, bags checked in must weigh less than 50 pounds. Betty packed 32 pounds of clothes and five gifts that weigh the same amount.
If each gift weighs w pounds, then the weight of five gifts will be 5w pounds and an additional 32 pounds of clothes will make it total (32 + 5w) pounds.
Now, this total weight has to be less than 50 pounds.
Therefore, the inequality equation that can be used to find the possible weight of each gift, w is

Find an equation of the line. Write the equation using function notation.
Through (3,-3); perpendicular to 4y=x-8
The equation of line perpendicular to 4y = x-8 passing through (3,-3) is:
[tex]y = -4x+9[/tex]
Step-by-step explanation:
Given equation of line is:
[tex]4y=x-8[/tex]
We have to convert the given line in slope-intercept form to find the slope of the line
So,
Dividing both sides by 4
[tex]\frac{4y}{4} =\frac{x-8}{4}\\y = \frac{1}{4}x-\frac{8}{4}\\y = \frac{1}{4}x-2[/tex]
Let m1 be the slope of given line
Then
[tex]m_1 = \frac{1}{4}\\[/tex]
Let m2 be the slope of line perpendicular to given line
As we know that produt of slopes of two perpendicular lines is -1
[tex]m_1.m_2 = -1\\\frac{1}{4} . m_2 = -1\\m_2 = -1*4\\m_2 = -4[/tex]
The slope intercept form of line is given by:
[tex]y = m_2x+b[/tex]
Putting the value of slope
[tex]y = -4x+b[/tex]
to find the value of b, putting (3,-3) in equation
[tex]-3 = (-4)(3) + b\\-3 = -12 +b\\b = -3+12\\b = 9[/tex]
Putting the value of b in the equation
[tex]y = -4x+9[/tex]
Hence,
The equation of line perpendicular to 4y = x-8 passing through (3,-3) is:
[tex]y = -4x+9[/tex]

Final answer:
The result is the equation f(x) = -4x + 9 in function notation.
Explanation:
To find the equation of a line that is perpendicular to another and passes through a given point, follow these steps:
First, determine the slope of the given line. The equation given is 4y = x - 8. To put this in slope-intercept form, divide everything by 4 to get y = ⅔x - 2. The slope (m) of this line is ⅔.To find the slope of a line perpendicular to this one, take the negative reciprocal of ⅔, which is -4.Now, using the point-slope form of a line equation, which is y - y1 = m(x - x1) where (x1, y1) = (3, -3) and m = -4, we get:Therefore, the equation of the line in function notation is f(x) = -4x + 9.
Two of the angles in a triangle measure 18° and 72°. What is the measure of the third angle?
Final answer:
To find the third angle of a triangle, add the two known angles and subtract from 180 degrees. In this case, the third angle measures 90 degrees since the sum of the two given angles is 90 degrees.
Explanation:
When determining the measure of the third angle in a triangle, we utilize the fundamental property that the sum of all angles in a triangle equals to 180 degrees. Given that two of the angles measure 18° and 72°, we can find the third angle by subtracting the sum of these two angles from 180°.
The calculation is as follows:
Add the two known angle measures: 18° + 72° = 90°.Subtract this sum from the total sum of angles in a triangle: 180° - 90° = 90°.Therefore, the measure of the third angle in the triangle is 90 degrees.

[tex] |x - 8| + 2 = 20[/tex]
Answer:
Solutions are -10 and 26
Step-by-step explanation:
( - the abolute sign I'm using
( x - 8 ) + 2 = 20
( x - 8 ) = 18
x - 8 = 18 (postive case)
x - 8 + 8 = 18 + 8
x = 26
( x - 8 ) = 18
x - 8 = -18 (negative case)
x - 8 + 8 = -18 + 8
x = -10
y =( x + 3) 2 - 1 identify the vertex
Answer:
Step-by-step explanation:
The vertex is of the form (h, k). The general equation of a quadratic in vertex form is
[tex]y=(x-h)^2+k[/tex]
where h is the x coordinate of the vertex and k is the y coordinate of the vertex. The important thing to remember is that the "x -" part of the formula is constant, it doesn't change. So if our expression inside the parenthesis is
(x + 3), it is understood to be (x - (-3)) which indicates movement to the left. The "+ k" part is not taken literally. If we have a + 2 at the end of our equation we are moving up 2; if we have a -1 at the end, we are moving down 1. Our vertex then is located at (-3, -1)
Henry, Brian and Colin share some sweets in the ratio 4:5:4. Henry gets 56 sweets. How many more sweets does Brian get over Colin?
Both Henry and Colin have a ratio of 4, so Colin gets the same amount as Henry, so we know Colin has 56.
Brian's ratio is 5, so for every 4 Colin gets, brian gets 5 ( 1 more).
Divide Colin's quantity by 4 :
56/4 = 14
Brain gets 14 more.

geometry math thanks if you help
Answer: Option B.
Step-by-step explanation:
For this exercise it is important to remember that, by definition, a relation is a function if and only if each input value has an unique output value.
The input values are the values of the variable "x" and the output values are the values of the variable "y".
You can observe in the table shown in the picture, that the input value -2 has two different output values:
[tex]x=-2,y=3\\\\x=-2,y=-13[/tex]
Notice that the input vale -1 has two different output values too:
[tex]x=-1,y=-1\\\\x=-1,y=-9[/tex]
Therefore, based on this, you can conclude that the information given in the table is a relation but not a function.

Question:
Set up a right triangle model for this problem and solve by using a calculator. Follow the models above,
A photographer stands 60 yards from the base of a lighthouse and observes that the angle between the ground and the top of the lighthouse is 41° How tall is the lighthouse?
Answer:
The height of lighthouse is 52.2 yards
Solution:
Given that photographer stands 60 yards from the base of a lighthouse and observes that the angle between the ground and the top of the lighthouse is 41 degree
The diagram is attached below
Consider a right angled triangle ABC
AB is the height of the lighthouse
BC is the distance between the base of a lighthouse and Photographer
As per given, BC = 60 yards
Angle between the ground and the top of the lighthouse is 41 degree
Angle ACB = 41 degree
To find: height of lighthouse i.e AB = ?
We know that,
[tex]tan(\angle ACB) = \frac{Perpendicular}{Base}[/tex]
Here Base is BC and perpendicular is AB
[tex]\tan 41^{\circ}=\frac{A B}{B C}[/tex]
Substituting the values,
[tex]\begin{aligned}&\tan 41^{\circ}=\frac{A B}{60}\\\\&0.8692=\frac{A B}{60}\\\\&A B=0.8692 \times 60=52.157 \approx 52.2\end{aligned}[/tex]
Thus the height of lighthouse is 52.2 yards

People at the state fair were surveyed about which type of
lemonade they preferred. The results are shown below.
Pink lemonade: 156 males, 72 females
Yellow lemonade: 104 males, 48 females
Answer:
Step-by-step explanation:
You would require the table with the number of males and females who prefer either pink or yellow lemonade at the state fair.
Pink Lemonade Yellow Lemonade TOTAL
Male 156 104 260
Female 72 48 120
TOTAL 228 152 380
P(pink lemonade | female) = 72 / (48 + 72) = 72 / 120 = 0.6
P(pink lemonade) = (156 + 72) / (156 + 72 + 104 + 48) = 228 / 380 = 0.6
Therefore, The event "prefers pink lemonade" and "female" are independent because P(pink lemonade | female) = P(pink lemonade) = 0.6
Answer:
P(pink lemonade | female) = P(pink lemonade) = 0.6.

The height of a wooden pole, h, is equal to 15 feet. Ataut wire is stretched from a point on the ground to the top of the pole. The
distance from the base of the pole to this point on the ground, b. is equal to 8 feet.
The question is incomplete. Here is the complete question:
The height of a wooden pole, h, is equal to 15 feet. A taut wire is stretched from a point on the ground to the top of the pole. The distance from the base of the pole to this point on the ground, b. is equal to 8 feet. What is the length of the wire?
Answer:
Length of wire = 17 feet
Step-by-step explanation:
Given:
The height of the wooden pole is, [tex]h=15\ ft[/tex]
The distance from the base of the pole to this point on the ground is, [tex]b=8\ ft[/tex]
Let the length of the wire be 'l'.
Now, consider the triangle formed by the pole, the base, and the wire. The length of the wire is the slant length and hence the hypotenuse of the triangle.
Using Pythagorean theorem, we can find the hypotenuse.
[tex](Hypotenuse)^2=(height)^2+(base)^2\\l^2=h^2+b^2[/tex]
Plug in the given values and solve for 'l'. This gives,
[tex]l^2=15^2+8^2\\\\l^2=225+64\\\\l^2=289\\\\l=\sqrt{289}\\\\l=\pm17[/tex]
As length can never be negative, we ignore the negative result.
Therefore, the length of the wire is 17 feet.

Describe the transformations of the graph of y=x that will produce the graph of
y = -(x + 2)2 +3.
The graph of y = x is transformed by a reflection about the x-axis, a horizontal translation to the left by 2 units, and a vertical translation upward by 3 units to produce the graph of y = -(x + 2)^2 + 3.
Explanation:The given equation is y = -(x + 2)^2 + 3, and we need to describe the transformations of the graph of y = x that will produce this graph.
The first transformation is the reflection about the x-axis, which is indicated by the negative sign in front of the original equation. This flips the graph upside down.
The second transformation is the horizontal translation to the left by 2 units, which is indicated by the addition of 2 inside the parentheses. This shifts the graph 2 units to the left.
The third transformation is the vertical translation upward by 3 units, which is indicated by the addition of 3 to the entire equation. This moves the graph 3 units up.

four times the area of the curved surface of a cylinder is equal to 6 times the sum of the areas of its bases. if its height is 12 cm find its curved surface area
Answer:
Step-by-step explanation:
Curved surface Area = 2πrh
Area of its bases = 2πr²
6* Area of its bases = 4 * Curved surface Area
6 * 2πr² = 4 *2πrh
r² / r = 4 * 2* π*12 / 6 * 2 * π { substituting h =12 cm}
r = 4*2
r = 8 cm
Curved surface Area = 2πrh
= 2 * 3.14 * 12 * 8
= 602.88 Sq. cm
Answer:
603.42
Step-by-step explanation:
Curved Surface Area = 2πrh sq.cm
Area of the base = πr² sq. cm
Sum area of the base = πr² + πr² = 2πr² sq.cm
A.T.Q
4(2πrh) = 6x2πr²
8πrh = 12πr²
2h = 3r
r = 8 cm
Curved Surface Area = 2πrh

The question asks for equivalent expressions to 3-8/3-4. After clarifying and simplifying the expression, we determined that the equivalent expressions are 3-12 (A) and 13/12 (F).
Explanation:The question is asking us to determine which expressions are equivalent to 3−83−4. First, let's clarify this expression. The symbols − and − can stand for subtraction or negative signs, making the expression ambiguous. However, we can interpret this as a subtraction problem with mixed numbers, which would be processed as 3 minus 8 thirds minus 4. Converting the mixed numbers to improper fractions, we get: 3−(8/3)−4 which simplifies to (9/3)−(8/3)−(12/3). This simplifies to 1/3−(12/3), or 1/3− 4, which then further simplifies to −(⅔).
When we look for equivalent expressions, we have the following options:
A) 3−12 is correct because it is the simplified form of 3 minus 8/3 minus 4, which is −3 1/3.B) 3−4 is incorrect because it simplifies to −1, which is not the same as −3 1/3.C) 3² is incorrect as this represents 3 squared, or 9, which is not the same as −3 1/3.D) 13² is incorrect because it represents 1/3 squared, which is 1/9, not the same as −3 1/3.E) 13´ could be construed as 13 to the power of 4 or 1/3 to the power of 4, but both interpretations are incorrect.F) 13⅜ is correct because it represents 1/3 minus 8/3 minus 4, which is −3 1/3.

Liza is driving to her sister's house 360 miles away. After 4 hours, Liza is 2/3 of the way there. How many more hours does Liza have to drive?
Answer:
Liza need to drive 2 more hours to reach her sister house
Solution:
Given that Liza is driving to her sister's house 360 miles away
So total distance = 360 miles
After 4 hours, Liza is 2/3 of the way there.
[tex]\frac{2}{3} r d \text { of total distance }=\frac{2}{3} \times 360=240[/tex]
So Liza has covered 240 miles in 4 hours
Let us find the speed
The relation between distance and speed is given as:
[tex]speed = \frac{distance}{time}[/tex]
[tex]speed = \frac{240}{4} = 60[/tex]
Thus speed = 60 miles per hour
Assuming speed is same throughout the journey, let us calculate the time taken to complete remaining distance
Remaining distance = 360 - 240 = 120 miles
Now distance = 120 miles and speed = 60 miles per hour
[tex]time taken = \frac{distance}{speed}\\\\time taken = \frac{120}{60} = 2[/tex]
Thus Liza need to drive 2 more hours to reach her sister house
Rita's family is moving to Grand Junction to Dallas. The moving van averages 60 miles each hour. About how many hours does the van take to reach Dallas? Explain your work
Answer:
16 hours and 20 minutes.
Step-by-step explanation:
Please consider the complete question.
Rita's family is moving to Grand Junction to Dallas, which is 980 miles. The moving van averages 60 miles each hour. About how many hours does the van take to reach Dallas?
To find the time taken by van to reach Dallas, we will divide total distance by speed.
[tex]\text{Time}=\frac{\text{Distance}}{\text{Speed}}[/tex]
[tex]\text{Time taken to reach Dallas}=\frac{980\text{ Miles}}{60\frac{\text{ Miles}}{\text{Hour}}}[/tex]
[tex]\text{Time taken to reach Dallas}=\frac{980\text{ Miles}}{60}\times \frac{\text{ Hour}}{\text{Miles}}[/tex]
[tex]\text{Time taken to reach Dallas}=\frac{98}{6}\text{ Hour}[/tex]
[tex]\text{Time taken to reach Dallas}=16.3333\text{ Hour}[/tex]
Let us convert 0.3333 hours into minutes by multiplying 0.3333 by 60.
[tex]0.3333\times 60=19.998\approx 20[/tex]
Therefore, it will take 16 hours and 20 minutes for the van to reach Dallas.
Final answer:
To calculate the time it takes for the van to reach Dallas, divide the distance from Grand Junction to Dallas by the average speed of the van.
Explanation:
To calculate the time it takes for the van to reach Dallas, we need to divide the distance from Grand Junction to Dallas by the average speed of the van.
The distance from Grand Junction to Dallas is not provided in the question, so we cannot calculate the exact time taken. However, if we are given the distance, we can use the formula:
Time = Distance / Speed
For example, if the distance is 300 miles, and the van's average speed is 60 miles per hour, then the time taken would be:
Time = 300 / 60 = 5 hours
