Answer:

A = 12 units ^2

Step-by-step explanation:

The area of the trapezoid is found by

A = 1/2 (b1+b2)h

b1 = 2

b2 = 4

h = 4

I found these by looking at the graph

A = 1/2(2+4) 4

A = 1/2(6*4)

A = 12 units ^2

Answer:

Step-by-step explanation:

The dividend refers to the percentage of a company's annual dividend compared to its share price.

In this case, according to the given table, we have a dividend of 5.72, which means that's the factor that tell us how much are we going to receive.

[tex]5.72 \times 25 = 143[/tex]

Therefore, we are gonna receive $143 due to the 25 shares with a dividend of 5.72.

So, the right answer is D.

Answer:

A. 63°

Step-by-step explanation:

Since line RU and line TU are tangent to the circle from a common point U, then RU = TU.

Therefore; Triangle RUT is an isosceles triangle.

Thus; m∠R = m∠T

Hence; m∠R = (180° -54°)/2

                     = 126°/2

                     = 63°

I believe it is 45 studs to the end of the wall

Answer:

Step-by-step explanation:

First, convert 20 yds to 60 ft. and then from 60 ft to 720 in.

Use the formula for the nth term of an arithmetic sequence:

l = a + (n-1)d:

Here l = 720 ft, and a = 0.  The common difference, d, is 16 in.  Our task is to determine how many studs are needed.

Substituting the knowns, we get 720 = 0 + (n - 1)(16), which simplifies to:

720 = (n-1)(16).

Divide both sides by 16 to isolate (n-1):  45 = n - 1.

Adding 1 to both sides results in 46 = n.

46 studs total are needed; if the worker has already placed the first stud, then 45 additional studs are needed.

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:

These 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.

Answer:

C. 10z(x - 2y)

Step-by-step explanation:

10xz − 20y

Factor the terms

Factors of   10xz =          2 ×      5 × x ×        z

Factors of -20yz = (-1) × 2 × 2 × 5 ×       y × z

Identify their greatest common  factor

The common factors are 2, 5, and z. The greatest common  factor is 10z.

Rewrite them with the GCF as a factor

 10xz = 10z ×      x

-20yz = 10z × (-2y)

Replace the terms in the original expression with the factored terms

10xz − 20yz = 10z(x) + 10z(-2y)

Use the distributive property to isolate the greatest common factor

10z(x) + 10z(-2y) = 10z(x - 2y)

Answer:

C. 10z(x - 2y)

Answer:

36m^2

Step-by-step explanation:

Divide the figure into 2 rectangles with the dimensions : 6 x 3 and 2 x 9

Then, use the rectangle area formula A = b * h

18 + 18 = 36

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°

I think it’s 9.10 but I’m not really sure

QP = 6

Step-by-step explanation:

We are given a line MP with a point on it Q and we are to find the length of the line segment QP.

We know that the length of MP is [tex] x + 17 [/tex], MQ is [tex]3[/tex] and QP is [tex] 2 x + 22 [/tex] so we can write it as:

[tex]MP=MQ+QP[/tex]

[tex]x+17=3+2x+22[/tex]

[tex]2x-x=17-22-3[/tex]

[tex]x=-8[/tex]

Substituting this value of x to find the length of QP:

QP = [tex] 2x +22 = 2(-8) +22 = [/tex] 6

Answer: 50

Step-by-step explanation: First of all, you need to establish your rate of acceptance. This would be 10 out of 48 or 10/48. Next, you need to simplify this to 5/24. Okay now this is epic. Now you need to convert 5/24 to x/240. Simple. Just multiply both sides by ten in 5/24 and you get your answer of 50. Very cool.

Final answer:

Michelle can expect approximately 50 students to join her book club based on the proportion of surveyed students who expressed interest.

Explanation:

Michelle surveyed 48 students, and 10 said they would join the book club. To estimate how many out of the total 240 students might join, we use proportions. The first step is to set up a proportion with the numbers Michelle has provided and then solve for the unknown:

Number of students surveyed who would join / Total students surveyed = Expected number who would join / Total students in grade

10 / 48 = x / 240

To find x, multiply both sides by 240:

240 * (10 / 48) = x

Then solve for x:

x = 50

Thus, Michelle could expect about 50 students to join the book club.

ANSWER

[tex]y = 3x - 3[/tex]

EXPLANATION

Let

[tex]y = mx + c[/tex]

be the equation.

We can choose any two ordered pairs to determine the equation of the relation.

[tex](6,15) \: and \: (8,21)[/tex]

We find m using the formula;

[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]

[tex]m = \frac{21 - 15}{8 - 6} = \frac{6}{2} = 3[/tex]

The equation becomes

[tex]y = 3x + c[/tex]

When x=6, y=15.

This implies that,

[tex]15 = 3(6) + c[/tex]

[tex]15= 18 + c[/tex]

[tex]15 - 18= c[/tex]

[tex]c = -3[/tex]

The equation of the relation is therefore,

[tex]y = 3x -3[/tex]

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.

Step-by-step explanation:

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.

Answer:

[tex]-\frac{4m^{4}n^{2}}{9}[/tex]

Step-by-step explanation:

The given expression is

[tex]=\frac{(2m^3n^2)^3}{-18m^5n^4}[/tex]

Use the power rule of indices on the denominator;[tex](a^m)^n=a^{mn}[/tex]

[tex]=\frac{8m^9n^6}{-18m^5n^4}[/tex]

We apply the quotient rule of indices; [tex]\frac{a^m}{a^n} =a^{m-n}[/tex]

[tex]=\frac{8m^9n^6}{-18m^5n^4}[/tex]

[tex]=-\frac{4m^{9-5}n^{6-4}}{9}[/tex]

Simplify

[tex]=-\frac{4m^{4}n^{2}}{9}[/tex]

Answer:

The correct answer is

(2m³n²)³/(-18m⁵n⁴) = - m⁴n²/9

Step-by-step explanation:

It is given an expression,

(2m³n²)³/(-18m⁵n⁴)

Points to remember

Identities

1).  (xᵃ)ᵇ  =  xᵃᵇ

2).  xᵃ/xᵇ = xᵃ⁻ᵇ

To solve the expression

(2m³n²)³/(-18m⁵n⁴) = -2m⁹n⁶/18m⁵n⁴    (Using identity 1)

 = -2/18(m⁹⁻⁵n⁶⁻⁴)     (Using identity 2)

 = -1/9(m⁴n²)

 = - m⁴n²/9

Therefore the simplified form of given expression is given by,

(2m³n²)³/(-18m⁵n⁴) = - m⁴n²/9

Answer: D. 648*π in^3

Step-by-step explanation:

The formula for the volume of a cylinder is

[tex]V=\pi *r^2*h[/tex]

V=1130.973355 in^3

or simply

V=1130.97 in^3

or

V=360*π  in^3

Since, you know the radius of the hemisphere on top, you also know the radius since the height of the hemisphere is the same as it is wide.

Next, the formula for the volume of a sphere is

[tex]V=\frac{4}{3} \pi *r^3[/tex]

since you have two hemispheres, its the same thing as solving for one sphere because two halves make a whole. So, the volume of the sphere is

V= 904.7786842 in^3

or simply

V= 904.78 in^3

or

V=288 *π  in^3

Finally, you add both of the volumes together to get

V= 2035.75204 in^3

or simply

V= 2035.75 in^3

or

V= 648*π  in^3
