Janell has a 10 inch by 12 inch photograph. She wants to scan the photograph
Complete Question:
Janeel has a 10 inch by 12 inch photograph. She wants to scan the photograph, then reduce the results by the same amount in each dimension to post on her Web site. Janeel wants the area of the image to be one eight of the original photograph. Write an equation to represent the area of the reduced image. Find the dimensions of the reduced image.
Correct Answer:
A) [tex](10-x)(12-x)=15[/tex]
B) Dimensions are : Length = 10-x = 3 inch , Breadth = 12-x = 5 inch
Step-by-step explanation:
a. Write an equation to represent the area of the reduced image.
Let the reduced dimensions is by x , So the new dimensions are
[tex]length=10-x\\breadth=12-x[/tex]
According to question , Area of new image is :
⇒ [tex]Area = \frac{1}{8}Length(breadth)[/tex]
⇒ [tex]Area = \frac{1}{8}(10)(12)[/tex]
⇒ [tex]Area = 15[/tex]
So the equation will be :
⇒ [tex](10-x)(12-x)=15[/tex]
b. Find the dimensions of the reduced image
Let's solve : [tex](10-x)(12-x)=15[/tex]
⇒ [tex]120-10x-12x+x^2=15[/tex]
⇒ [tex]120-22x+x^2=15[/tex]
⇒ [tex]x^2-22x+105=0[/tex]
By Quadratic formula :
⇒ [tex]x = \frac{-b \pm \sqrt{b^2-4ac} }{2a}[/tex]
⇒ [tex]x = \frac{22 \pm8 }{2}[/tex]
⇒ [tex]x = \frac{22 +8 }{2} , x = \frac{22 -8 }{2}[/tex]
⇒ [tex]x = 15 , x =7[/tex]
x = 15 is rejected ! as 15 > 10 ! Side can't be negative
⇒ [tex]x =7[/tex]
Therefore, Dimensions are : Length = 10-x = 3 inch , Breadth = 12-x = 5 inch

5. Graph the given relation or equation and find the domain and range. Then determine whether the relation or equation is a function.
(3.9, 5.9), (–1.1, 5.9), (–4.1, 3.9), (–4.1, –2.1)
Given:
Given that the coordinates are (3.9, 5.9), (–1.1, 5.9), (–4.1, 3.9), (–4.1, –2.1)
We need to determine domain and range and also find whether the relation is a function.
Domain:
The domain is the set of all independent x - values.
Thus, we have;
[tex]Domain=\{3.9,-1.1,-4.1\}[/tex]
Thus, the domain is {3.9,-1.1,-4.1}
Range:
The range is the set of all dependent y - values.
Thus, we have;
[tex]Range=\{5.9,3.9,-2.1\}[/tex]
Thus, the range is {5.9,3.9,-2.1}
Function:
We need to determine whether the given relation is a function.
For a relation is said to be a function, if every value of x has only one image in the y - coordinate.
After plotting the graph, it is obvious that the x - value -4.1 has two images 3.9 and 2.1
Hence, the given relation is not a function.

The measure of arc BD is __.
The measure of arc ADB is __.
The measure of arc ABC is __.
PLEASE HELP. URGENT!! ASAP
- The measure of arc [tex]\( BD \)[/tex] is 260°.
- The measure of arc [tex]\( ADB \)[/tex] should be 320° (corrected).
- The measure of arc [tex]\( ABC \)[/tex] is 80°.
To find the measure of each arc in the circle, we need to remember that the total degrees in any circle is 360°. The diagram shows a circle with specific arcs and angles labeled.
Here are the steps to find each arc's measure:
1. Measure of arc [tex]\( BD \)[/tex]:
- Arc [tex]\( BD \)[/tex] is opposite the central angle [tex]\( \angle BRD \)[/tex], which is not directly given.
- Since [tex]\( \angle BRC \)[/tex] is 40° and [tex]\( \angle CRD \)[/tex] is 60°, then [tex]\( \angle BRD = 360° - (\angle BRC + \angle CRD) \)[/tex].
- Calculating [tex]\( \angle BRD \)[/tex] gives [tex]\( 360° - (40° + 60°) = 260° \)[/tex].
- Therefore, the measure of arc \( BD \) is 260°.
2. Measure of arc [tex]\( ADB \)[/tex]:
- Arc [tex]\( ADB \)[/tex] includes arcs [tex]\( AD \)[/tex] and [tex]\( DB \)[/tex].
- We already know [tex]\( DB \)[/tex] is 260°.
- [tex]\( AD \)[/tex] is opposite the central angle [tex]\( \angle ARD \)[/tex], which is given as 120°.
- Adding them together, the measure of arc [tex]\( ADB = \angle ARD + \angle BRD = 120° + 260° = 380° \).[/tex]
- This exceeds 360°, which suggests an error. Since [tex]\( AD \)[/tex] and [tex]\( BD \)[/tex] are parts of the circle that add up to its whole circumference, they should add up to 360°, not more. Hence, [tex]\( ADB \)[/tex] should be [tex]\( 360° - \angle BCD \)[/tex] which is 360° - 40° = 320°.
3. Measure of arc [tex]\( ABC \)[/tex]:
- Arc [tex]\( ABC \)[/tex] includes arcs [tex]\( AB \)[/tex] and [tex]\( BC \).[/tex]
- [tex]\( BC \)[/tex] is opposite the central angle [tex]\( \angle BRC \)[/tex], which is given as 40°.
- [tex]\( AB \)[/tex] is the rest of the circle not included in \( ADB \), so [tex]\( AB = 360° - \angle ADB \)[/tex].
- Since we've found an inconsistency with [tex]\( ADB \)[/tex], we should instead calculate [tex]\( AB \)[/tex] as [tex]\( 360° - (BD + CD) = 360° - (260° + 60°) = 40° \).[/tex]
- Adding \( AB \) and \( BC \), the measure of arc [tex]\( ABC = AB + BC = 40° + 40° = 80° \).[/tex]
There seems to be an error with the measure of arc [tex]\( ADB \)[/tex] as calculated before. Arcs [tex]\( AD \)[/tex] and [tex]\( DB \)[/tex] should add up to 360° because they complete the circle together. It's also worth noting that in a properly drawn circle, the sum of the measures of arcs [tex]\( BC \)[/tex], [tex]\( CD \)[/tex], and [tex]\( DA \)[/tex]should add up to 360°. If [tex]\( BC \)[/tex] is 40° and [tex]\( CD \)[/tex] is 60°, then [tex]\( DA \)[/tex] should be 360° - (40° + 60°) = 260°, not 120°. This discrepancy suggests there may be a mistake in the given information or a misinterpretation of the diagram.
To summarize, given the information provided:
- The measure of arc [tex]\( BD \)[/tex] is 260°.
- The measure of arc [tex]\( ADB \)[/tex] should be 320° (corrected).
- The measure of arc [tex]\( ABC \)[/tex] is 80°.
Have three witches each holding a broom and a spoon. Witches say witch plus witch plus witch =45. Three brooms say broom plus broom plus a broom =21 and three spoons say spoon plus spoon plus spoon = 12 then final question is a plain witch plus broom x spoon equal a ? What’s answer?
Answer:
a=43
Step-by-step explanation:
w+w+w= 45 which means 15+15+15=45
b+b+b=21 which means 7+7+7=21
s+s+s=12 which means 4+4+4=12
w+b×s= a which means 15+7×4= 43
(hope this helps)
Answer:
The answer to the question is 43
Step-by-step explanation:
Let us recall the values from the following question stated:
Three witches each holds a broom and a spoon, saying plus witch plus witch = 45
Three brooms say broom plus broom plus a broom at = 21
Three spoons say spoon plus spoon plus = 21
Now, let us find when a plain witch plus broom x spoon
Then,
Three witches = 45, resulting to 15+15+15=45
Three brooms (b+b+b) which is =21 or 7+7+7=21
Three spoons (s+s+s) is =12 or 4+4+4=12
we make use of multiplication for the witches, the brooms, and the spoons
Therefore
w+b×s= a, which is 15+7×4= 43

There's 6,954 cases filed with Surpreme court only 82 were chosen by Surpreme court. what percentage was decided by the court ?
Answer:
1.2%
Step-by-step explanation:
Since only 82 were chosen by supreme Court,
The total is 6954
To calculate the percentage of the case decided by the court
82/6954 ×100
8200/6954
1.179~1.2
So the final answer is 1.2%
Final answer:
The percentage of cases decided by the Supreme Court compared to those filed is approximately 1.18%.
Explanation:
To calculate the percentage of cases decided by the Supreme Court out of the total number of cases filed, we use the formula for finding a percentage: (Number of cases decided / Total cases filed) × 100. In this scenario, the Supreme Court decided 82 cases out of 6,954 cases filed.
So, the calculation would look like this:
(82 / 6,954) × 100 = (0.01179) × 100 ≈ 1.18%
Therefore, approximately 1.18% of the cases filed with the Supreme Court were decided by the court.
The water temperature required for a certain manufacturing process is 134°F. However, the process allows for a variation of 7°F in the water temperature.
If x represents the water temperature, which inequality describes the situation? What is the range of water temperatures that is allowed for this process?
Answer:
The temperature that represents a smaller value would be the one with negative eighty (or -80) degrees Fahrenheit. Although it is negative, the value of 80 does not mean it has a smaller value as to 134 degrees. It is just that the difference between the absolute values of the two show that 134 degrees Fahrenheit has a bigger value.

c. 1.1x - 3.01y
Step-by-step explanation:
a) 2.56x + 0.14 − 1.87x
To simplify this algebraic expression, you start by collecting like terms;
2.56x − 1.87x + 0.14
Then perform arithmetic operation
0.69x + 0.14
b) 7.32a + 2.1 (2.7 − 18a)
Here; first, the bracket must be opened
To open the bracket; each expression in the bracket is multiplied by 2.1. This leaves us with
7.32a + 2.1 * 2.7 − 2.1 * 18a
7.32a + 5.67 - 37.8a
Then, you collect like terms
7.32a - 37.8a + 5.67
Then perform arithmetic operation
-30.48a + 5.67
Rearrange
5.67 - 30.48a
c) 0.12x + 0.34y + 0.98x − 3.35y
Here, you start by collecting like terms
0.12x + 0.98x + 0.34y − 3.35y
Then perform arithmetic operation
1.1x - 3.01y

The perimeter of triangle ABC = 12 cm.
The area of triangle ABC is
the area of triangle DEF.
The correct statements of the triangle are; AC = 5 cm; BA = 4 cm; The perimeter of triangle ABC is 12 cm.
What are the correct statements of the Triangles?As we know that a, b, and c are midpoints of the sides of right triangle that means midpoint divide the side in equal parts.
Now we have to calculate the sides of triangle ABC by using Pythagoras theorem.
Using Pythagoras theorem in ΔACF :
AC² = FA² + CF²
Thus;
AC² = 3² + 4²
AC = √25
AC = 5
Using Pythagoras theorem in ΔDAB, we have;
BA = √(5² - 3²)
BA = 4 cm
Using Pythagoras Theorem, we have;
CB = √(5² - 4²)
CB = 3 cm
Perimeter of ΔABC = Side AB + Side CB+ Side AC
Perimeter of ΔABC = 4 + 3 + 5
Perimeter of ΔABC = 12 cm
Area of ΔABC = (1/2) * 4 * 3 = 6 cm²
Area of ΔDEF = (1/2) * 8 * 6 = 24 cm²
Area of ΔABC = (6/24) * Area of ΔDEF

Given the information provided, we can determine the lengths of the sides of triangle ABC and its perimeter and area.
Explanation:Given that points A, B, and C are midpoints of the sides of right triangle DEF, we can determine the lengths of the sides using the information provided.
BC = 6 cmAC = 5 cmBA = 4 cmDE = 10 cmFD = 6 cmFE = 8 cmTo find the perimeter of triangle ABC, we sum the lengths of all three sides: AB + BC + CA. Substituting the given lengths, AB = BA = 4 cm, BC = 6 cm, and CA = AC = 5 cm, the perimeter is 4 cm + 6 cm + 5 cm = 15 cm.
The area of triangle ABC can be determined using the formula A = bh, where b is the base and h is the height. Triangle ABC and triangle DEF are similar triangles, so their areas are proportional. Since point A is the midpoint of DE, half the base of triangle DEF is equal to the base of triangle ABC. Substituting the given length of DE = 10 cm, the base of triangle ABC is 10 cm / 2 = 5 cm. The height of triangle ABC is equal to the length of AC = 5 cm. Therefore, the area of triangle ABC is A = 5 cm * 5 cm = 25 cm².

Diego has a skateboard, scooter, bike and go-cart. he wants to know which vehicle, is the fastest. a friend records how far diego traveles on each vehicle in 5 seconds. for each vehicle, diego travels as fast as he can along a straight path vehicle skateboard path=90 feet scooter=1,020 bike=4,800 centimeters go kart=0.03 kilometers a.100 inches equal 245 centimeters whatis the distance each vehicle traveled in centimers? ?
Answer:
1. Skateboard: 2,743.2. Scooter: 2,590.8. Bike: 4,800. Go-cart: 3,000.
After converting all distances to centimeters, it's clear that Diego's bike traveled the furthest (4800 cm) in 5 seconds, making it the fastest.
Explanation:Understanding the speed of Diego's vehicles requires us to convert the distances all to the same unit, centimeters. First, we know that 1 foot equals 30.48 cm. Therefore, the skateboard traveled 90 feet * 30.48 cm/foot = 2743.2 cm. The scooter traveled 1020 feet, which means it traveled 1020 feet * 30.48 cm/foot = 31,089.6 cm. The bike traveled 4800 cm, so no conversion is needed for this vehicle. Lastly, 1 kilometer equals 100,000 cm, meaning the go-kart traveled 0.03 kilometers * 100,000 cm/kilometer = 3,000 cm. Now that we have all the distances in the same unit, we can compare and state that the bike traveled the furthest in 5 seconds, making it the fastest.

The angle of elevation from L to K measures 24°. If KL = 19, find JL. Round your answer to the nearest tenth.
Answer:
jl = 19cos24 = 17.4. jk = 19sin24 = 7.7.
Step-by-step explanation:
We have a rt. triangle; the hyp is kl
and the hor side is jl. The angle between the hor side and hyp = 24 deg.
The value of JL rounding up to the nearest tenth will be 17.36.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
In another word, the angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.
Angle is the measurement of rotation motion for example if you want to measure the length in rotation geometry then it is helpful.
Given that the KL = 19 units, the angle LJK = 24°
Now by a trigonometric function
cos24° = Jl/19
JL = 19 × cos24°
JL = 17.36 hence, the correct answer or the length of the JL is 17.36 units.
