If y = 2x - 1 and (3, 5) and (4, 7) are part of the pattern then what is the y coordinate of (5, __ )? A) 8 B) 9 C) 10 D) 11
Answers
Answer:
(5, 9)
Step-by-step explanation:
Substitute the x- coordinate of the point into the equation to evaluate the y- coordinate, that is
x = 5 : y = (2 × 5 ) - 1 = 10 - 1 = 9 → B
Hence the coordinates of the point are (5, 9 )
Final answer:
Using the equation y = 2x - 1, the y-coordinate for the point (5, __) is calculated to be 9 by substituting x = 5 into the equation, resulting in the value that fits the identified pattern.
Explanation:
The question asks for the y-coordinate of the point (5, __) based on the pattern described by the equation y = 2x - 1. We see that the given points (3, 5) and (4, 7) fit this pattern, as plugging x = 3 into the equation gives y = 2(3) - 1 = 5, and plugging x = 4 into the equation gives y = 2(4) - 1 = 7. To find the y-coordinate for the point where x = 5, we can follow the same arithmetic pattern.
Using the equation, we plug in x = 5:
y = 2(5) - 1
= 10 - 1
= 9
Therefore, the y-coordinate for the point (5, __) is 9, which corresponds to option B.

That brings that to our equation 5:4.
Have an amazing day.
The ratio of trumpet players to saxophone players in the band is 4:5. This means there are 4 trumpet players for every 5 saxophone players.
To find the ratio of trumpet players to saxophone players in the band, we need to compare the numbers of each type of player.
The number of trumpet players is 4.The number of saxophone players is 5.We express the ratio of trumpet players to saxophone players as 4 to 5, which is written as 4:5.So, the ratio of trumpet players to saxophone players in the band is 4:5.
This means that for every 4 trumpet players, there are 5 saxophone players.
In ΔVWX, the measure of ∠X=90°, XV = 27 feet, and WX = 57 feet. Find the measure of ∠V to the nearest degree.
Answers
Answer:
[tex]<V=65\°[/tex]
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
In the right triangle VWX
[tex]tan(V)=\frac{WX}{XV}[/tex] -----> opposite side angle V divided by the adjacent side angle V
substitute the values
[tex]tan(V)=\frac{57}{27}[/tex]
[tex]<V=arctan(\frac{57}{27})=65\°[/tex]
Final answer:
To find the measure of ∠V, we take the ratio of XV to WX (opposite to adjacent side) and use the tangent function. By calculating tan(∠V) = 27/57 and taking the inverse tangent, we get ∠V ≈ 25° to the nearest degree.
Explanation:
To find the measure of ∠V in ∆VWX, where ∠X=90°, XV = 27 feet, and WX = 57 feet, we use the trigonometric ratios, specifically the tangent function, since we are dealing with a right-angled triangle and we have the lengths of the opposite side (XV) and the adjacent side (WX) to ∠V.
Step by Step Solution:
Use the definition of the tangent function: tan(∠V) = opposite/adjacent.
Substitute the known values: tan(∠V) = XV/WX = 27/57.
Calculate tan(∠V) = 0.4737.
Find the angle whose tangent is 0.4737 using an inverse tangent function on a calculator: ∠V ≈ 25° (to the nearest degree).
Therefore, the measure of ∠V is approximately 25°.

In the same circle, chord AB determines a 115° arc and chord AC determines a 43° arc. Find m∠BAC.
Answers
Answer:
36° or 101°
Step-by-step explanation:
Consider the figures given in the attachment.
Point C can be between A and B as shown in the left image of the attachment or outside AB chord as shown in the right image.
In both figures, ∠AOB = 115° and ∠AOC = 43°.
Both the triangles are isoceles triangle as OC and OA side is equal in ΔAOC and OA and OB is equal in ΔAOB.
In ΔAOC,
∠A + ∠O + ∠C = 180°
∠A = ∠C
∴ 2 ∠A =180-43=137°
∴∠A = 68.5
In ΔAOB,
∠A + ∠B + ∠O = 180°
∠A = ∠B
∴2 ∠A = 180-115=65°
∴∠A = 32.5°
For figure on the left side,
∠BAC = ∠OAC - ∠OAB = 68.5 - 32.5 =36°
For figure on right side,
∠BAC = ∠OAC + ∠OAB = 68.5 + 32.5 =101°
3. Mrs. LeBlanc is making a Pokémon box. The length of the box is 12 inches greater than its width, and its height is 5 inches less than its width. Find the dimensions of the Pokémon box formed, given that its volume is 9600 cubic inches. (Show all work including setting up the equation, simplifying the equation, listing the possible rational roots, testing the possible rational roots using synthetic division, and then identifying all of the dimensions.
Answers
Answer:
The width is 20 inches, the length is 32 inches and the height is 15 inches.
Step-by-step explanation:
Let x inches be the width of the box. If the length of the box is 12 inches greater than its width, then the length of the box is x+12 inches. If the height of the box is 5 inches less than its width, then the height of the box is x-5 inches.
The volume of box is
[tex]V=\text{length}\cdot \text{width}\cdot \text{height}\ in^3.[/tex]
Therefore,
[tex]9600=x\cdot (x+12)\cdot (x-5).[/tex]
Solve this equation:
[tex]x(x^2+12x-5x-60)=9600,\\ \\x^3+7x^2-60x-9600=0.[/tex]
The integer solutions of this equation can be among the divisors of -9600. The divisors of 9600 are:
[tex]\pm1, \pm2, \pm3, \pm4,\pm5,\pm6,\pm8,\pm10,\pm12,\pm15,\pm16,\pm20,\pm24,\pm25,\pm30,\pm32,....[/tex]
We can check all these divisors and see that x=20 is a solution, then using synthetic division
[tex]x^3+7x^2-60x-9600=(x-20)(x^2+27x+480).[/tex]
Since the quadratic factor has discriminant [tex]D=27^2-4\cdot 480=-1191<0,[/tex] we can state that the only solution is x=20 inches. The width is 20 inches, the length is 32 inches and the height is 15 inches.

To find the contribution of each man (this is a sexist problem as women could work as well, but that’s besides the point) take 5/2 and then multiply that value by 20 and you’ll find it takes 50 hours for two men to do it.
Answer: 50 hours
Answer:
50 hours.
Step-by-step explanation:
To solve these type of question we should always remember that man power is inversely proportionate to the work done.
That means if we double the manpower work done will be half. and when we reduce the manpower to the half time take to complete the work will be double.
It takes 5 men to brick a house = 20 hours
so 1 man will brick the house = 20 × 5
= 100 hours
Therefore, 2 men will brick the house = [tex]\frac{100}{2}[/tex]
= 50 hours.

What are four common denominators for 1/4 & 1/2
Answers
I am pretty sure that it is 8,12,16 and 20
if not plz forgive me
The common denominators for 1/4 and 1/2 are:
8421These denominators are found by identifying the multiples of the denominators of 1/4 and 1/2.
The question at hand involves finding four common denominators for the fractions 1/4 and 1/2. A common denominator is a shared multiple of the denominators of two or more fractions. This task is essential for operations like addition, subtraction, or comparison of fractions.
4: This is the most obvious choice since 4 is the denominator of one of the fractions, and 2 is a factor of 4. Hence, 1/2 can be expressed as 2/4.
8: Doubling the first common denominator gives us 8. In this case, 1/4 becomes 2/8 and 1/2 is 4/8.
12: Multiplying the denominators 4 and 2 gives us another common denominator, 12. Thus, 1/4 can be expressed as 3/12 and 1/2 as 6/12.
20: Choosing a higher number that is divisible by both 4 and 2. Here, 1/4 is 5/20 and 1/2 becomes 10/20.
These examples show how to scale the numerators accordingly to maintain the value of the original fractions while having the same denominator.

What is the percent of decrease from 10 to 3?
Write your answer using a percent sign (%).
Answers
The percent of decrease from 10 to 3 can be calculated by finding the difference between the two numbers, dividing this difference by the original number, and multiplying the result by 100. This method gives us a decrease of 70%.
Explanation:The question is looking to find the percent of decrease between two numbers, specifically from 10 to 3. To calculate this, we first find the difference between the two numbers (which is 10 - 3 = 7), then divide this difference by the original number (7 divided by 10 equals 0.7) and finally multiply the result by 100 to convert it to percentage form. This gives us a 70% decrease.
Here are the step-by-step calculations:
Find the difference between the two numbers: 10 - 3 = 7.Divide the difference by the original number: 7 / 10 = 0.7.Multiply the result by 100 to convert to a percentage: 0.7 x 100 = 70%.So, the decrease from 10 to 3 is 70%.

ABEF=CBED. The perimeter of CBED is 17. Find the length of BE
Answers
2.7. Because of the CPCTC theorem, like CB is equal to 5.9 so if you add the lengths of CB, CD, and ED and subtract this by 17, you find the length of BE which is 2.7
Answer:
Option B, 2.7 is the answer.
Step-by-step explanation:
Perimeter of CBED = CD + ED + BC + BE
17 = 5.6 + 2.8 + 5.9 + BE
